Amino acid residues in the transmembrane domain of the type 1 sigma receptor critical for ligand binding. (1/262)

The type 1 sigma receptor expressed in Xenopus oocytes showed binding abilities for the sigma-1 ligands, [3H](+)pentazocine and [3H]NE-100, with similar kinetic properties as observed in native tissue membranes. Amino acid substitutions (Ser99Ala, Tyr103Phe and di-Leu105,106di-Ala) in the transmembrane domain did not alter the expression levels of the type 1 sigma receptor as determined by immunoblot analysis using an anti-type 1 sigma receptor antiserum. By contrast, ligand binding was significantly suppressed by the substitutions. These findings provide evidence that the transmembrane domain of the type 1 sigma receptor plays a critical role in ligand binding of this receptor.  (+info)

A-Current down-modulated by sigma receptor in frog pituitary melanotrope cells through a G protein-dependent pathway. (2/262)

Gramicidin perforated patch-clamp recordings were used to study the effects of two sigma 1 receptor ligands, (+)-N-cyclopropylmethyl-N-methyl-1, 4-diphenyl-1-ethyl-but-3-en-1-ylamine hydrochloride (JO 1784) and (+)-pentazocine, on the transient outward potassium current (IA) in cultured frog melanotrope cells. (+)-Pentazocine reversibly decreased the current amplitude in a dose-dependent manner. The effects of (+)-pentazocine were mimicked by JO 1784 and were markedly reduced by the sigma 1 receptor antagonist, N, N-dipropyl-2-[4-methoxy-3-2(2-phenylethoxy)phenyl]-ethylamine monohydrochloride (NE 100). Inactivation rate of IA was best fitted with a double exponential function, yielding time constants of 23.7 and 112.5 ms. (+)-Pentazocine (20 microM) accelerated the current decay, decreasing the time constants to 10.7 and 59 ms, respectively. Current-voltage experiments revealed that (+)-pentazocine (20 microM) did neither modify the open-state I/V curves nor the voltage dependence of IA. However, (+)-pentazocine (20 microM) shifted the steady-state inactivation curve toward more negative potentials and increased the time constant of the time-dependent removal of inactivation. In whole-cell experiments, internal dialysis of guanosine-5'-O-(3-thiophosphate) (100 microM) irreversibly prolonged the response to (+)-pentazocine. In addition, cholera toxin pretreatment (1 microgram. ml-1; 12 h) suppressed the inhibition of IA by (+)-pentazocine (20 microM). It is concluded that in frog melanotrope cells, a cholera toxin-sensitive, G protein-dependent inhibition of IA through a sigma 1 receptor activation, at least partially, underlies the excitatory effect of sigma ligands.  (+info)

Sigma1 recognition sites in rabbit iris-ciliary body: topical sigma1-site agonists lower intraocular pressure. (3/262)

In this study, we examined the presence of sigma1 and sigma2 sites in the rabbit iris-ciliary body by receptor binding and investigated their effects on intraocular pressure (IOP) in albino rabbits. The iris-ciliary body has binding sites for the sigma1-site agonist [3H](+)-pentazocine (Kd = 4.6 nM; Bmax = 212 fmol/mg protein) and sigma2 sites labeled with [3H]1,3-di-o-tolylguanidine (DTG) (Kd = 8. 2 nM; Bmax = 1120 fmol/mg protein). In competition binding studies, (+)-pentazocine and the sigma antagonist NE-100 displayed high affinity for sigma1 sites (Ki = 2.1 and 2.4 nM, respectively), whereas (+)-N-allylnormetazocine (NANM) was less potent (Ki = 178 nM). Unilateral topical (+)-pentazocine (0.01-0.1%) caused a significant dose-related reduction of IOP in ocular normotensive rabbits and in the alpha-chymotrypsin model of ocular hypertension. (+)-NANM was less potent than (+)-pentazocine. Neither compound altered the IOP of the contralateral eye, and their hypotensive activity was blocked by NE-100 that, by itself, had no effect on IOP. (-)-Pentazocine, (-)-NANM, and DTG had no effect on IOP. DTG prevented the hypotensive effect of (+)-pentazocine, suggesting that it acts as a sigma1-site antagonist. sigma-Site ligands did not affect pupil diameter or cause ocular inflammation. Topical [3H](+)-pentazocine reaches the intraocular tissues within 30 min, and its uptake in the iris-ciliary body and retina was significantly reduced by topical pretreatment with NE-100, as expected for a receptor-specific agent. Reverse-phase HPLC confirmed the presence of intact (+)-pentazocine in iris-ciliary body homogenates. sigma1-Site agonists may offer a novel class of agents potentially effective in the control of ocular hypertension.  (+info)

Mechanism-based inactivation of rat liver cytochrome P-450 2B1 by 2-methoxy-5-nitrobenzyl bromide. (4/262)

Mechanism-based inactivators serve as probes of enzyme mechanism, function, and structure. Koshland's Reagent II (2-methoxy-5-nitrobenzyl bromide, KR-II) is a potential mechanism-based inactivator of enzymes that perform O-dealkylations. The major phenobarbital-inducible form of cytochrome P-450 in male rat liver microsomes, CYP2B1, is capable of catalyzing O-dealkylations. The interactions of KR-II with purified CYP2B1 in the reconstituted system containing P-450, NADPH:P-450 oxidoreductase, and sonicated dilaurylphosphatidyl choline were studied. The benzphetamine N-demethylase activity of CYP2B1 was inactivated by KR-II in a time- and NADPH-dependent manner, and the loss of activity followed pseudo-first-order kinetics. The inactivation also required KR-II, and the rate of activity loss was dependent on the concentration of KR-II in a saturable fashion. The inactivator concentration required for the half-maximal rate of inactivation (KI) was approximately 0.1 mM. The inactivation was not prevented by the addition of the nucleophiles dithiothreitol and glutathione, nor was it reversed by gel filtration. The present results demonstrate that KR-II is a mechanism-based inactivator of rat CYP2B1.  (+info)

Odor response properties of rat olfactory receptor neurons. (5/262)

Molecular biology studies of olfaction have identified a multigene family of molecular receptors that are likely to be involved in odor transduction mechanisms. However, because previous functional data on peripheral coding were mainly collected from inferior vertebrates, it has been difficult to document the degree of specificity of odor interaction mechanisms. As a matter of fact, studies of the functional expression of olfactory receptors have not demonstrated the low or high specificity of olfactory receptors. In this study, the selectivity of olfactory receptor neurons was investigated in the rat at the cellular level under physiological conditions by unitary extracellular recordings. Individual olfactory receptor neurons were broadly responsive to qualitatively distinct odor compounds. We conclude that peripheral coding is based on activated arrays of olfactory receptor cells with overlapping tuning profiles.  (+info)

New studies on trans-anethole oxide and trans-asarone oxide. (6/262)

The widespread use of naturally occurring alkenylbenzenes as flavoring and fragrance agents has led to a long-standing interest in their toxicity and carcinogenicity. Among them several allyl- and propenylbenzenes have been found to be mutagenic and carcinogenic. It has been shown that the carcinogenicity of several allylbenzenes can be related to the formation of electrophilic sulfuric acid esters following 1'-hydroxylation. Unlike the allylbenzenes, the mechanisms of carcinogenesis of propenylbenzenes such as anethole and asarone are not clear. It has been reported that one of the main metabolic pathways of trans-anethole is the epoxidation of the side chain 1,2-double bond, which was responsible for cytotoxicity but not for genotoxicity. However, we report here that synthetic trans-anethole oxide prepared from trans-anethole and dimethyldioxirane is not only mutagenic for Salmonella tester strains but is also carcinogenic in the induction of hepatomas in B6C3F1 mice and skin papillomas in CD-1 mice. Synthetic trans-asarone oxide was also carcinogenic in the induction of hepatomas as well as mutagenic for Salmonella strains. Further studies are needed on these side chain oxides of trans-anethole and trans-asarone as possible metabolites in the toxicity, mutagenicity and carcinogenicity of these and other propenylbenzenes.  (+info)

Dose-response trend tests for tumorigenesis, adjusted for body weight. (7/262)

Several studies have demonstrated a relationship between rodent body weight and tumor incidence for some tissue/organ sites. It is not uncommon for a chemical tested for carcinogenicity to also affect body weight. In such cases, comparisons of tumor incidence may be biased by body-weight differences across dose groups. A simple procedure was investigated for reducing this bias. This procedure divides the animals into a few groups based on body weight. Body weight at 12 months was used, before the appearance of a tumor was likely to affect body weight. Statistics for dose-response trend tests are calculated within body weight strata and pooled to obtain an overall dose-response trend test. This procedure is analogous to that currently used, of stratifying animals, based on their age at the time of removal from a study. Age stratification is used to account for differences in animal age across dose groups, which can affect comparisons of tumor incidence. Several examples were investigated where the high-dose group had reduced body weights and associated reductions in tumor incidence. When the data were analyzed by body-weight strata, some positive dose-response trends for tumor incidence were demonstrated. In one case, the weight-adjusted analysis indicated that a negative dose-response trend in tumor incidence was a real effect, in addition to a body weight reduction. These examples indicate that it is important to consider the effects of body weight changes as low as 10%, and perhaps below, that were caused by chemicals in 2-year bioassays for carcinogenesis. The simple procedure of analyzing tumor incidence within body-weight strata can reduce the bias introduced by weight differences across dose groups.  (+info)

Induction of apoptosis in leukemic cells by the reversible microtubule-disrupting agent 2-methoxy-5-(2',3',4'-trimethoxyphenyl)-2,4,6-cycloheptatrien-1 -one: protection by Bcl-2 and Bcl-X(L) and cell cycle arrest. (8/262)

We have found that the bicyclic colchicine analogue 2-methoxy-5-(2',3',4'-trimethoxyphenyl)-2,4,6-cycloheptatrien-1-on e (MTC) induced a dose- and time-dependent apoptotic response in human leukemic cells. MTC and colchicine rapidly disrupted the microtubule integrity and arrested cells at the G2-M phase before the onset of apoptosis. These responses were mediated by microtubule inhibition because 2-methoxy-5-[[3-(3,4,5-trimethoxyphenyl)propionyl]amino]-2,4,6-cycloh eptatrien-1-one and lumicolchicine, inactive analogues of MTC and colchicine, respectively, were unable to promote microtubule disassembly, cell cycle arrest, and apoptosis. Although 1 microM MTC induced a complete microtubule disruption after 1 h of incubation in human leukemic HL-60 cells that led to an accumulation of cells at the G2-M phase, MTC-induced apoptosis occurred after 9 h of treatment. This indicates the existence of a rather long lag between microtubule disruption and the onset of apoptosis. Unlike colchicine, the removal of MTC during this lag resulted in rapid microtubule repolymerization, followed by restoration of normal cell cycle and cell growth. MTC, but not 2-methoxy-5-[[3-(3,4,5-trimethoxyphenyl)-propionyl]amino]-2,4,6-cyclo heptatrien-1-one, induced c-jun expression as well as c-Jun NH2-terminal kinase and caspase activation, indicating that these signaling pathways are triggered by the specific action of MTC on microtubules. Caspase inhibition prevented MTC-induced apoptosis. Overexpression of bcl-2 or bcl-xL by gene transfer in human erythroleukemic HEL cells abrogated MTC-induced apoptosis, but cells remained arrested in G2-M, suggesting that bcl-2 and bcl-xL block the signaling pathway between G2-M arrest and triggering of apoptosis. MTC-treated bcl-2 and bcl-xL-transfected HEL cells recovered their capacity to proliferate after MTC removal. These results indicate that microtubule inhibition induces G2-M arrest and apoptosis in leukemic cells, showing a lag phase between G2-M arrest and the onset of apoptosis, regulated by bcl-2 and bcl-xL, during which MTC displays a reversible action on microtubule depolymerization and G2-M cell cycle arrest. Thus, MTC is a potent apoptotic inducer on human leukemic cells and shows a remarkable reversible action on microtubule network and cell cycle before commitment for apoptosis is reached.  (+info)

Abstract : The objective of the present study was to evaluate the impact of biofield energy treatment on the thermal,spectroscopic, and chemical properties of anisole by various analytical methods such as gas chromatography-massspectrometry (GC-MS), high performance liquid chromatography (HPLC), differential scanning calorimetry (DSC),Fourier transform infrared (FT-IR) spectroscopy, and ultraviolet-visible (UV-Vis) spectroscopy. The anisole sample wasdivided into two parts, control and treated. The control part was remained same while the other part was treated withMr. Trivedis unique biofield energy treatment. Mass spectra showed the molecular ion peak with five fragmented peaksin control and all treated samples. The isotopic abundance ratio of 2H/1H, and 13C/12C [(PM+1)/PM] in treated samplewas increased by 154.47% (T1) as compared to the control [where, PM- primary molecule, (PM+1)-isotopic moleculeeither for 13C or 2H].

I dont think polarization is the issue. Adding $\ce{FeBr3}$ is just to reduce the $\ce{Br-Br}$ bond strength, speeding up the reaction (attack of the aromatic ring on the bromine is part of the rate determining step, which is slow in the bromination of benzene). It functions as a catalyst being recycled when the $\ce{Br-}$ grabs a $\ce{H+}$ to restore aromaticity in the ring. Im pretty sure - at least I see no reason to doubt - that the catalyst requirements for the bromination of anisole and the bromination of phenol do not differ much, if at all. That is, no catalyst is required for the bromination of anisole.. ...
First order-like plots, due to the large excess of methoxide, are obtained in each case, except with methyl benzoate (Plot 3) where metallic copper appeared after 1 hour (decomposition of catalyst). Slope ratio between the blank experiment (Plot 1) and the ethyl acetate one (Plot 6) is superior to 20, demonstrating the effectiveness of this co-catalyst (completion is reached within 45 min., with a quasi-quantitative yield).. Use of ethyl rather than methyl esters leads sometimes to traces of 2-ethoxy phenol (0.5 to 1%), due to releasing of ethoxide ion through transesterification of the co-catalyst by methoxide; methyl esters may therefore be preferred if highest purity of final product is required.. Anisole is also quasi-quantitatively obtained from bromobenzene in presence of ethyl acetate (10 mmole PhBr, 4 mmol EtOAc, 1,4 mmol CuBr in 6 ml 5M MeONa/MeOH, 98% conversion after 1h reflux, 100% after 2h, yield of isolated anisole >95% without detected phenetole)..

We have studied the pyrolysis of aromatic combustion intermediates using an array of detection techniques. The molecules investigated include cyclic aromatic molecules with hydrocarbon substituents (ethylbenzene, n-propylbenzene, isopropylbenzene, and styrene), oxygen-containing substituents (anisole and phenol), triply substituted systems (vanillin), resonance stabilized radicals (benzyl radical and tropyl radical) and phenyl radical. At the exit of a resistively heated micro-reactor (1 mm inner diameter, 3 cm long), the pyrolysis fragments are detected using photoionization mass spectrometry (PIMS), matrix isolation vibrational spectroscopy, microwave spectroscopy, tunable VUV synchrotron-based PIMS, and table-top VUV PIMS with photoelectron photoion coincidence spectroscopy (PEPICO). This array of detection methods allows for the identification of all possible fragments including metastables, radicals, and atoms. The findings allow for detailed mechanistic information regarding which pathways ...

The cell wall protein peptidoglycan complex (CW-PPC) ofMycobacterium tuberculosis H37Ra was isolated through sequential extraction of lipids, carbohydrates and soluble proteins. CW-PPC emulsified in FIA was found to induce significant protection in mice against challenge with LD50 dose ofM. tuberculosis H37Rv. To identify the immunoprotective components of CW-PPC, the proteins in avid association with peptidogican were dissociated by chemical treatment with trifluoromethanesulthonic acid (CF3CO3H): anisole (2:1). Immunoreactivity of total (CW-Pr) as well as its component proteins i.e., 71, 60 and 45 kDa proteins of cell wall was studied in animals immunized with CW-Pr-FIA. The 71 kDa protein was found to be most immunoreactive giving higher T-cell sensitization and humoral responses. Further, immunization of mice with 71 kDa-FIA demonstrated enhanced T- and B- cell responses. Mice immunized with 71 kDa-FIA gave significantly higher protection (P ≤ 0.05) against intravenous challenge with LD50 ...

A metabolite of beta-asarone is the reason Acurus calamus is known in some cultures as a psychedelic. However, not all Acorus calamus contains sufficient quantities of beta-asarone to be effective. Acorus calamus from Nepal typically contains a large amount of beta-asarone. Acorus calamus from India usually contains very little beta-asarone, and will cause extreme nausea before doses high enough to get some minor effects from beta-asarone are ingested.. Its important to note that beta-asarone itself is not active. One of its metabolites can produce psychedelic effects in man. Not everyones body metabolizes beta-asarone the same way, leading to different results for different individuals. Some people are not able to experience psychedelic effects from ingesting beta-asarone. This is because their bodies do not produce enough of the active metabolite to experience effects.. The active metabolite of beta-asarone is currently unidentified. There has been speculation of it being an amphetamine, ...

Outside of the human body, 1-Methoxy-4-(2-propenyl)benzene is found, on average, in the highest concentration within a few different foods, such as anises, fennels, and sweet basils and in a lower concentration in cumins, tarragons, and parsley. 1-Methoxy-4-(2-propenyl)benzene has also been detected, but not quantified in, several different foods, such as citrus, chinese cinnamons, caraway, fats and oils, and cloves. This could make 1-methoxy-4-(2-propenyl)benzene a potential biomarker for the consumption of these foods. 1-Methoxy-4-(2-propenyl)benzene, with regard to humans, has been linked to ...

Most of the ADCs currently in the market and in clinical development carry tubulin polymerization inhibitors such as T-DM1 and SGN-35 (Brentuximab vedotin; ref. 13). We synthesized a novel ADC with a topoisomerase I inhibitor, which has a different mechanism of action from tubulin polymerization inhibitors, and a novel self-immolative linker system using an aminomethylene (AM) moiety. Although other cleavable linker systems applied to SGN-35 (Brentuximab vedotin) and several ADCs release amino group-containing payloads, this AM self-immolative linker system is able to release DXd containing the hydroxyl group from DS-8201a. Moreover, this novel linker-payload system enables a reduction in the hydrophobicity of the ADC and helps increase its DAR. In the case of T-DM1, lysine conjugation and noncleavable systems are used, and it is quite a different system from DS-8201a. DS-8201a showed potent HER2-specific efficacy both in vitro and in vivo, and by drug conjugation maintained the functional ...
The authors of the AVRO study also assert that, while both treatments were found to be safe and well tolerated, vernakalant had "low proarrhythmic potential and provides a rapidly acting therapeutic alternative".. The research team, led by Professor John Camm from St. Georges University of London, conducted a randomized, double-blind, multicenter superiority trial in 254 adult patients with underlying cardiovascular disease, making certain antiarrhythmic drugs inappropriate for use. 116 patients in each group received at least one dose of the study drug. Approximately 30% of patients in both treatment arms had no AF episodes prior to the initial diagnosis, whereas one-third had at least three.. Those in the vernakalant study arm received a 10-minute infusion of 3 mg/kg followed by an additional 10-minute infusion of 2 mg/kg if needed after a 15-minute observation period. Amiodarone patients received a 60-minute infusion of 5 mg/kg followed by an additional 60-minute maintenance infusion of 50 ...
The first indication in determining the quality of wine is if there is presence of any faults. The more common ones include cork taint (TCA) and oxidation and can be detected when an aroma or flavor in the wine appears off or just wrong. Cork taint occurs when 2,4,6 - Tricloranisole or TCA, generated by naturally-occurring fungi that often exist in the crevices of wood or cork, comes into contact with chlorine compounds present in pesticides, cleaning agents, wood treatments, etc. When cork taint occurs, the wine will have a musty, moldy aroma. Controlling the source of TCA has proven extremely difficult and currently there are no solutions.. Another wine fault is the oxidation or reduction of the wine - which happens when wines are either exposed to too much or too little oxygen respectively. When oxidation occurs, this usually results in a breakdown of its attractive color. Whites go a dull brown/straw, rosés go brown/orange, reds become paler with an orange/brown rim. Chilling grapes and ...
The present study reports densities (ρ), viscosities (η) and ultrasonic speeds (U) of pure dioxane (DOX), anisole (ANS), toluene (TOL) and ethylbenzene (ETB) and their binary liquid mixtures over the entire composition range at 293, 298, 303, 308 and 313 K. From the experimental data excess molar volume (VmE), excess intermolecular free length (LfE), excess adiabatic compressibility (βE) and excess acoustic impedance (ZE) have been computed. The excess values were correlated using Redlitch-Kister polynomial equation to obtain their coefficients and standard deviations (σ). With increase in temperature, the binary mixture of DOX+ANS shows larger deviations in βE, LfE and smaller deviations in ZE, VmE. These results suggest that ANS has strong molecular interactions with DOX than ETB and TOL.

Many would argue that the sense of smell is our far most important sense when it comes to evaluating wine. This is because the olfactory sense plays a fundamental role both in the perception of aroma and also flavour. Without it all wines,3 rather than just a few, would appear to be uninteresting alcoholic solutions of acid and sugar. The sense of smell is by far the most powerful of our senses. It can discriminate between tens of thousands of different aromas, and is capable of detecting some compounds found in wine at levels around a single part per trillion. An example of this is the compound 2,4,6 Trichloroanisole, the primary compound responsible for cork taint. Some people can detect it at around 1 part per trillion which is analogous to a single second in thirty two years. Not bad I suppose, but when you think that an Alsatian or Beagle probably sees a three dimensional colliedescope like scent world, our olfactory efforts seem pretty pathetic in comparison. The olfactory system ...

The ability of headspace SPME, in combination with analysis on the SLB-5ms, to detect a low level of 2,4,6- trichloroanisole (TCA) in wine is shown in Figure 4. TCA is often the source of the musty smell in wine resulting from tainted corks. Red wine obtained in a bottle fitted with a metal screw cap was spiked with TCA and the headspace was extracted using SPME. Analysis was done by GC-MS/SIM on the SLB-5ms. The compound was detected in a spiked wine sample at 5 parts-per-trillion (ppt), which is well below the 40 ppt sensory threshold level in red wines (3).. ...

In just six weeks..... I have seen and released 24 clients from trauma using IEMT. The results have been astonishing and I am beyond delighted with the effects its had on them and their loved ones.. I qualified as a Life Coach in 2004 and for the last two years have been working as such, with both local and remote clientele. In March this year I myself was diagnosed with PTSD and a client recommended Matt Kendall and IEMT. I had just three sessions and my life changed.. By May I knew that I wanted to qualify as a practitioner and bring this therapy to my existing and future clients. I just knew that this horrible diagnosis had happened for a reason.. By September I was ready to turn the page on the new chapter to come and attended Matts workshop in London where I met several other pracitioners of all genres. The training was excellent and Matt was extremely thorough in delivery of both theory and practise. But theres nothing quite like getting your hands dirty on the coal face so I could wait ...

Butylated hydroxyanisole was tested for carcinogenicity in two experiments in rats and in two experiments in hamsters by administration in the diet, inducing benign and malignant tumours of the forestomach.. Butylated hydroxyanisole was studied in mice and rats for its ability to modify the carcinogenicity of selected chemical agents. When administered with known carcinogens, butylated hydroxyanisole either enhanced, inhibited or had no effect on carcinogenicity.. Butylated hydroxyanisole administered to rats at maternally toxic and occasionally lethal doses during, or before, during and after, gestation induced slight embryotoxicity but no definite indication of teratogenicity. No effect was seen in rabbits, pigs or rhesus monkeys.. In rats, feeding of butylated hydroxyanisole in the diet caused superficial necrosis, ulceration and hyperplasia of the squamous epithelium of the forestomach. Induction of forestomach hyperplasia also occurs in hamsters. Administration of butylated hydroxyanisole ...
A novel series of tubulin polymerization inhibitors, based on fluorinated derivatives of isocombretastatin A-4 was synthesized with the goal of evaluating the effect of these compounds on the proliferative activity. The introduction of fluorine atom was performed on the phenyl ring or at the linker between the two aromatic rings. The modification of isoCA-4 by introduction of difluoromethoxy group at the para-position (3i) and substitution of the two protons of the linker by two fluorine atoms (3m), produced the most active compounds in the series, with IC50 values of 0.15-2.2 nM (3i) and 0.1-2 nM (3m) respectively, against a panel of six cancer cell lines. Compounds 3i and 3m had greater antiproliferative activity in comparison with references CA-4 or isoCA-4, the presence of fluorine group leads to a significant enhancement of the antiproliferative activity. Molecular docking studies indicated that compounds 3i and 3m occupy the colchicine binding site of tubulin. Evaluation of cytotoxicity in ...

The general belief that chemical structure determines the biological effect of drugs has led to several techniques to establish structure-activity relationships (SAR) that is useful in the development of more active compounds. Predicting toxic effects based on SAR, one can obtain toxicological data with a low cost-benefit ratio. Chlorophenols that represent a class of toxic agents frequently used in industrial processes are not satisfactorily described in the literature in relation to their toxicity. The main objective of this work is to relate the microbial activities of phenol, anisole and their chlorinated derivatives on Chromobacterium violaceum respiration with their physicochemical properties. Anisole and its chlorinated derivatives were used to evaluate the influence of phenol acidity on biological activity. The calculations were carried out at the semi-empirical AM1 and ab initio DFT levels employing the basis sets CEP-31G, CEP-31+Ge CEP-31G** that were parameterized using the ...

Also known as aniseed, anise (Pimpinella anisum) is an annual herb perhaps best known for its signature licorice-like flavor and spicy-sweet scent. It can reach a height of 2 feet, is covered in soft hairs, and bears white flowers and oblong schizocarp fruits. Aniseed should not be confused with star anise (Illicium verum), which is an entirely different plant that merely shares a similar flavor and scent profile. Aniseed is cultivated in southern Europe, Turkey, central Asia, India, China, and Japan, as well as Central and South America.. Anise seeds naturally contain flavonoids and fatty oils, as well as its main component anethole. These seeds have been used in cuisines around the world for their licorice-like flavor, and are popularly distilled to extract their spicy-sweet smelling essential oil. Anise seeds have also been used in ancient Egypt to make tea, by ancient Roman naturalist Pliny the Elder, and in traditional European wellness practices for an array of applications, such as in ...

Butylated Hydroxyanisole/Butylated Hydroxytoluene is a chemical preservative that is added to oils that are used in dog foods and treats. BHA is a combination of isomers 3-tert-butyl-4-hydroxyanisole and 2-tert-butyl-4-hydroxyanisole and BHT is a mixture of 3,5-di-tert-butyl-4-hydroxytoluene; methyl-di-tert-butylphenol; and 2,6-di-tert-butyl-para-cresol.. The ingredient is derived from natural preservatives that are found in all dry dog food. Its added to commercial products to extend the shelf life of the product by up to a year, and is one of the more inexpensive preservatives available. The FDA states that it can be used safely to preserve the fats and oils that are added to the pet food and to prevent them from spoiling or becoming oxidized. Its also easy for dogs to digest, but is known as a possible carcinogen by the State of California. BHA/BHT is commonly used in cosmetics, petroleum, embalming fluids and pesticides. Although its deemed to be safe to use, studies have shown that the ...
The accelerating effect of mature males of the desert locust,Schistocerca gregaria, on the maturation of immature male and female conspecifics was confirmed. The onset of sexual activity was found to correlate with yellowing of the male insects. Using the colour as an indicator of maturation, the maturation-hastening effect of an hexane extract from mature males was also confirmed. Likewise, volatiles from mature males placed in the upper storey of a two-chamber bioassay system (no visual or tactile contact possible) and charcoal-trapped volatiles from the mature males also induced accelerated maturation in recipient males placed in the lower storey. GC and GC-MS analysis of volatiles collected from 4-week-old mature males showed the presence of anisole, benzaldehyde, veratrole, phenylacetonitrile and 4-vinylveratrole, roughly at the ratio 4.8:7.0:3.3:79.8:5.0. In addition, guaiacol, phenol, benzoylnitrile, benzyl alcohol and 2-benzoyloxyphenylacetonitrile were present in smaller amounts. These ...
Seed coat crude extracts of white-coloured ITA-256, white and brown-coloured TVS-716, deep brown-coloured IT-90K and light brown-coloured Ife brown cowpea varieties were analyzed for the presence and amount of total phenol, tannin and flavonoid content. Crude extracts of the cowpea varieties were analyzed for antioxidant activity using the Thiobarbituric Acid (TBA) assay. The seed coat extracts were added sepa-rately to 200 g of minced broiler meat sample at the rate of 0.05% of the weight of the meat and their effect compared to that of the synthetic antioxidant, butylated hydroxyl anisole (BHA) added to the meat at the rate of 0.05%. Each sample was divided into 16 parts of 12.5 g each. Eight of these were cooked while the other 8 parts were left raw. Antioxidant effect of the seed coat extracts was determined during refrigerated storage of raw and cooked minced broiler meat.

Butylated hydroxyanisole (BHA) is a commonly used food additive with demonstrated inhibitory action against chemical carcinogenesis in animals. In order to elucidate the mechanism of the anticarcinogenic action, the effects of BHA on benzo(a)pyrene (BP) metabolism were studied with lung microsomes from female mice. BHA treatment (0.5% in the diet for 7 days) inhibited BP metabolism and altered the ratios among different metabolites as analyzed by high-performance liquid chromatography. The treatment reduced the metabolic formation of 9,10-dihydroxy-9,10-dihydrobenzo(a)pyrene, but not the production of 3-hydroxybenzo(a)pyrene and trans-4,5-dihydroxy-4,5-dihydrobenzo(a)pyrene. Since the gross microsomal cytochrome P-450 content was not significantly affected by the treatment, the change of regioselectivity in BP metabolism was probably due to the alteration of cytochrome P-450 isozyme composition by dietary BHA. General and regioselective inhibition of BP metabolism was also observed when BHA was ...
FENNEL. The same oils found in anise are found in fennel, giving both the tell-tale odor and taste of licorice. One of these oils, anethole, is believed to have anti-fungal and anti-bacterial properties. Known primarily for its use in Italian dishes, the fennel bulb contains the B vitamin complex but boasts a high amount of folate in particular. Fennel also contains vitamin C, calcium, copper, iron, magnesium, manganese, potassium, selenium and zinc.. The fennel bulb, which resembles a fattened celery bunch base, can be sliced thin and eaten raw in salads. In its raw form, it has a fresh, cool, mild flavor. To impart more of an anise flavor, cook the fennel. Any cooking method that induces caramelization, such as braising, roasting or grilling, will add a sweet element close to candied licorice. The entire plant is edible. So dont toss the dill-like leaves which can be utilized like an herb in any dish.. ...
Chemicals causing musty smells are mostly produced by Actinomycetes, Streptomyces, Cyanobacteria and other bacteria, fungi and algae. Examples of compounds responsible for musty odor are Geosmin (muddy, resembling damp soil, produced by Streptomyces), trichloroanisole (TCA, smelling like damp cellar, usually produced from chlorinated phenolic compounds by Aspergillus, Penicillium, Actinomycetes, Botrytis cinerea, Rhizobium, or Streptomyces), tribromoanisole (TBA, produced from brominated phenolic compounds by the same bacteria), dimethylmethoxypyrazine (obnoxious musty odor that might be caused by Pseudomonas and Actinobacteria), 2-methylisobomeol (earthy, peat-like), 3-methylbut-2-ene-1-thiol, cis-3-octenal, nonanal, decanal. ...

Abstract : Study background: 1,2,3-Trimethoxybenzene is an important compound used for the synthesis of chemicals and pharmaceutical agents. The objective of this study was to investigate the influence of biofield energy treatment on the physical, thermal and spectral properties of 1,2,3-trimethoxybenzene. Methods: The study was performed by dividing the sample into two groups (control and treated). The control group remained as untreated, while the treated group received Mr Trivedis biofield energy treatment. The control and treated 1,2,3-trimethoxybenzene samples were then characterized by X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR) spectroscopy, and ultra violetvisible spectroscopy (UV-Vis) analysis. Results: XRD studies revealed the significant increase in crystallite size of treated sample by 45.96% as compared to the control sample. DSC analysis showed a decrease in melting temperature of the ...
Thrombosis is defined as a condition of formation of a blood clot inside a blood vessel, leading to the obstruction of blood flow of the circulatory system. Anrise can help to reduce the risk of thrombosis due to the essential oil anethole, according to the study of "Protective effect of Foeniculum vulgare essential oil and anethole in an experimental model of thrombosis" by Tognolini M, Ballabeni V, Bertoni S, Bruni R, Impicciatore M, Barocelli E., posted in PubMed (2), researchers found that both F. vulgare essential oil and anethole (100 mg kg(-1) oral administration) provided significant protection toward ethanol induced gastric lesions in rats. In conclusion, these results demonstrate for F. vulgare essential oil, and its main component anethole, a safe antithrombotic activity that seems due to their broad spectrum antiplatelet activity, clot destabilizing effect and vasorelaxant action ...
Fennel is a flowering plant of the celery family which is indigenous to the Mediterranean & has since spread throughout most of the world thanks to the popularity of its seed as a culinary spice, possessing the flavors of anise, citrus, & mild notes of camphor. Constituents anethole (50 to 80%), limonene, fenchone, methyl-chavicol, safrole, a-pinene, camphene, b-pinene, b-myrcene and p-cymene Fennel seeds are commonly seen in Indian cuisine & are also eaten after meals to improve digestion & freshen the breath. When brewed into tea fennel produces a sweet tasting drink that soothes the stomach & eliminates flatulence. Fennel seeds are one of the main ingredients in masala chai teas, having a combined sweet & aromatic profile while improving digestion & settling the stomach. The strongest note of fennel is that of anise, however there are strong secondary notes of orange peel zest & camphor which produce an almost wintergreen type of undertone that balances & sweetens the licorice like notes from the
Anise (Pimpinella anisum L.) is an annual spice and medicinal plant belonging to the family Apiaceae. Only a limited number of anise breeding studies are available. Therefore, genetic variation among anise landraces has not been extensively examined with molecular markers. In this study, the molecular diversity of 15 Turkish anise landraces collected from different regions of Turkey and four foreign landraces obtained from Cyprus, Syria and France were analyzed using randomly amplified polymorphic DNA (RAPD) and inter simple sequence repeat (ISSR) markers. The discriminatory power of these markers was assessed by calculating various marker parameters, namely percent polymorphism, polymorphism information content (PIC), resolving power (RP), and marker index (MI). The genomic DNA of 19 anise landraces was amplified with nine RAPD primers that generated 71 polymorphic bands and five ISSRs primers that produced 45 polymorphic bands. The percentage of polymorphic loci was 59.8% in RAPD profiling and ...
New research from the University of Minnesotas Institute on the Environment and Stanford University shows that freshwater stream ecosystems are highly vulnerable to oil palm plantation expansion.. The three-year study compared streams draining watersheds dominated by four land uses - intact forest, manually logged forest, community agroforest and oil palm plantation - in West Kalimantan, Indonesian Borneo, which is ground zero for palm oil production.. Kimberly Carlson, an IonE postdoctoral scholar and lead author on the study, says the research yielded some unexpected findings. "First, oil palm plantation land use seems to have a greater effect on streams than community agroforest or low-impact logging." Researchers were also surprised to discover that a stream in a mature, closed-canopy oil palm plantation was almost as hot as, and yielded even more sediment than, a stream draining a watershed recently cleared for oil palm.. The study, published in the Journal of Geophysical Research: ...
Bulb fennel is one of three varieties of fennel which all belong to the same species, Foeniculum vulgare. One variety is a leafy herb of which the leaves and herbs are used in baked goods, teas and flavoring in candy. There is also the Sicilian fennel which has tender stems that are eaten like celery. Lastly, there is bulb fennel, also known as Florence fennel, or finocchio. This is what we grow. This type of fennel is biennial (although I have seen it produce in seeds in its first year before). Fennel is in the Apiaceae family, along with carrots and dill. The ancient Greeks grew it for food, medicine and insect repellent. Fennel tea was served just before important battles to instill courage in warriors. It is also said that the ancient Greeks believed it had a slimming effect on overweight people, and that may be why it was called "marathon," from the word "maraino" meaning to grow thin. Today, fennel is used to relieve abdominal cramps and flatulence ...
