Interactions of antitumor triazoloacridinones with DNA. (1/13)

Triazoloacridinones (TA) are a new group of potent antitumor compounds, from which the most active derivative, C-1305, has been selected for extended preclinical trials. This study investigated the mechanism of TA binding to DNA. Initially, for selected six TA derivatives differing in chemical structures as well as cytotoxicity and antitumor activity, the capability of noncovalent DNA binding was analyzed. We showed that all triazoloacridinones studied stabilized the DNA duplex at a low-concentration buffer but not at a salt concentration corresponding to that in cells. DNA viscometric studies suggested that intercalation to DNA did not play a major role in the mechanism of the cytotoxic action of TA. Studies involving cultured cells revealed that triazoloacridinone C-1305 after previous metabolic activation induced the formation of interstrand crosslinks in DNA of some tumor and fibroblast cells in a dose dependent manner. However, the detection of crosslink formation was possible only when the activity of topoisomerase II in cells was lowered. Furthermore, it was impossible to validate the relevance of the ability to crosslink DNA to biological activity of TA derivatives.  (+info)

Design, synthesis, and evaluation of 10-N-substituted acridones as novel chemosensitizers in Plasmodium falciparum. (2/13)

A series of novel 10-N-substituted acridones, bearing alkyl side chains with tertiary amine groups at the terminal position, were designed, synthesized, and evaluated for the ability to enhance the potency of quinoline drugs against multidrug-resistant (MDR) Plasmodium falciparum malaria parasites. A number of acridone derivatives, with side chains bridged three or more carbon atoms apart between the ring nitrogen and terminal nitrogen, demonstrated chloroquine (CQ)-chemosensitizing activity against the MDR strain of P. falciparum (Dd2). Isobologram analysis revealed that selected candidates demonstrated significant synergy with CQ in the CQ-resistant (CQR) parasite Dd2 but only additive (or indifferent) interaction in the CQ-sensitive (CQS) D6. These acridone derivatives also enhanced the sensitivity of other quinoline antimalarials, such as desethylchloroquine (DCQ) and quinine (QN), in Dd2. The patterns of chemosensitizing effects of selected acridones on CQ and QN were similar to those of verapamil against various parasite lines with mutations encoding amino acid 76 of the P. falciparum CQ resistance transporter (PfCRT). Unlike other known chemosensitizers with recognized psychotropic effects (e.g., desipramine, imipramine, and chlorpheniramine), these novel acridone derivatives exhibited no demonstrable effect on the uptake or binding of important biogenic amine neurotransmitters. The combined results indicate that 10-N-substituted acridones present novel pharmacophores for the development of chemosensitizers against P. falciparum.  (+info)

Antitumour properties of acridone alkaloids on a murine lymphoma cell line. (3/13)

The aim of the present study was to investigate the anticancer properties of a set of furanoacridone alkaloids, arborinine and evoxanthine, including the inhibitory effect of P-glycoprotein (Pgp) and the apoptosis-inducing capacity. The tested alkaloids were evaluated for multidrug resistance (MDR)-reversing activity on human Pgp-transfected L5178 mouse lymphoma cells, using the rhodamine-123 (Rh-123) assay. The antiproliferative effects of natural compounds and their interactions with doxorubicin were determined in MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assays. Apoptosis-inducing activity was additionally measured by means of dual annexin V and propidium iodide staining. RT-PCR was used to test the expression of Pgp mRNA after acridone treatment. All of the acridones investigated increased the accumulation of Rh-123. Gravacridonetriol and gravacridonediol monomethyl ether increased the antiproliferative effect of doxorubicin on resistant L5178 cells. Treatment with these agents resulted in a decrease in Pgp mRNA levels. Naturally occurring acridone alkaloids exhibit a beneficial combination of anticancer effects and, accordingly, the acridone skeleton can be considered useful in the design of novel antiproliferative agents.  (+info)

Isolation of acridone alkaloids and N-[(4-monoterpenyloxy)phenylethyl]-substituted sulfur-containing propanamide derivatives from Glycosmis parva and their anti-herpes simplex virus activity. (6/13)

Six acridone alkaloids including a new glycosparvarine (1), three limonoids, and four N-[(4-monoterpenyloxy)phenylethyl]-substituted sulfur-containing propanamide derivatives including two new species, (+)-S-deoxydihydroglyparvin (10) and (+)-S-deoxytetrahydroglyparvin (11), were isolated from the branches and the leaves of Glycosmis parva CRAIB collected in the east of Thailand. Antiviral activity evaluation of isolates against herpes simplex virus (HSV) type 1 and 2 disclosed that two acridone alkaloids, glycosparvarine (1) and glycofolinine (4), showed moderate inhibitory activities with 50% effective concentration (EC50) of 348 microM and 151 microM, respectively; as well, (+)-S-deoxydihydroglyparvin (10) exhibited anti-HSV activity at the lower concentration.  (+info)

Natural and synthetic acridines/acridones as antitumor agents: their biological activities and methods of synthesis. (7/13)

Acridine derivatives constitute a class of compounds that are being intensively studied as potential anticancer drugs. Acridines are well-known for their high cytotoxic activity; however, their clinical application is limited or even excluded because of side effects. Numerous synthetic methods are focused on the preparation of target acridine skeletons or modifications of naturally occurring compounds, such as acridone alkaloids, that exhibit promising anticancer activities. They have been examined in vitro and in vivo to test their importance for cancer treatment and to establish the mechanism of action at both the molecular and cellular level, which is necessary for the optimization of their properties so that they are suitable in chemotherapy. In this article, we review natural and synthetic acridine/acridone analogs, their application as anticancer drugs and methods for their preparation.  (+info)

What might the reaction energy diagram of electrophilic aromatic substitution look like?. First, the overall appearance is determined by the number of transition states in the process.. Recall that transition states always have partial bonds and are at the peaks of a reaction energy diagram, and intermediates such as carbocations are in the valleys between peaks. Intermediates can be observed and isolated (at least in theory); in contrast, transition states have a lifetime of femtoseconds, and although they may fleetingly be observed in certain cases, they can never be isolated.. Electrophilic aromatic substitution has two steps (attack of electrophile, and deprotonation) which each have their own transition state. There is also a carbocation intermediate. This means that we should have a double-humped reaction energy diagram.. Second, the relative heights of the peaks should reflect the rate-limiting step.. Whats the slow step? In other words, which of the two steps has the highest ...
L-DOPA and manganese both induce oxidative stress-mediated apoptosis in catecholaminergic PC12 cells. In this study, exposure of PC12 cells to 0.2 mM MnCl2 or 10-20 μM L-DOPA neither affected cell viability, determined by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, nor induced apoptosis, tested by flow cytometry, fluorescence microscopy, and the TUNEL technique. L-DOPA (50 μM) induced decreases in both cell viability and apoptosis. When 0.2 mM MnCl2 was associated with 10, 20, or 50 μM L-DOPA, a concentration-dependent decrease in cell viability was observed. Apoptotic cell death also occurred. In addition, manganese inhibited L-DOPA effects on dopamine (DA) metabolism (i.e., increases in DA and its acidic metabolite levels in both cell lysate and incubation medium). The antioxidant N-acetyl-L-cysteine significantly inhibited decreases in cell viability, apoptosis, and changes in DA metabolism induced by the manganese association with L-DOPA. An increase in ...
The breadth of clinically relevant β-lactamase enzymes in a wide range of Enterobacteriaceae species continues to contribute to a growing global clinical challenge, where even drugs of last resort such as the carbapenems are no longer predictably reliable. S-649266 is a novel siderophore cephalosporin antibiotic with a catechol moiety on the 3-position side chain. The addition of the catechol moiety enables the active transport of S-649266 into bacterial cells via iron transport systems. This molecular technique of harnessing the cells own essential survival mechanisms to increase the penetration of the antimicrobial agent has been described as a Trojan horse approach (14). Since the iron transporters are strongly regulated by the surrounding iron concentrations (24), the culture medium for the MIC determination of S-649266 was supplemented with an iron chelator (human apo-transferrin) to mimic the limited free iron condition present in human biological fluids (21).. In the first ...
Hospitality to visitors is usually a virtue,1 but in this fallen world it is important to understand exactly who is being invited before welcoming him with open arms-as the ancient Trojans learned, to their destruction. Although Troy was brought down in physical battle, Christians today face ideological Trojan horses that wait to enter and destroy faith.. Worldview-corrupting Trojan horses have repeatedly visited the Christian community, as is illustrated by Drs. John Whitcomb and Henry Morris in their pivotal work The Genesis Flood.. The Original Trojan Horse. The original Trojan horse was a military trick used by Greeks to defeat Troy, according to Virgils legendary epic The Aeneid.2 The Greeks had besieged Troy for years, without success. So they plotted a new strategy, one dealing in distraction and deceit. The Greek army secretly constructed a colossal wooden statue shaped as a horse, Troys lucky animal, with a hollow space inside. Inside the hollow were Greek soldiers, lying in ...
The title complex, (I), was obtained in an extension of the work on the synthesis of polycyclic heteroaromatic systems in the double nucleophilic aromatic substitution reaction using o-dichlorobenzene FeCp and related complexes (Sutherland et al., 1982, 1988), followed by modification of the heterocycle structure by oxidation (see Lee et al., 1986, and earlier work by the same authors). This study continues our observations of changes that result in the structure of tricyclic heterocycles containing O and/or S atoms in the central ring of the system upon FeCp complexation and the introduction of substituents into a heterocycle structure. The free heterocycle, phenoxathiin 10,10-dioxide, (II), was obtained in an oxidation of phenoxathiin with hydrogen peroxide in glacial acetic acid solution, as described by Gilman & Esmay (1952).. The unit cell of (I) contains four cationic molecules of the (phenoxathiin 10,10-dioxide) FeCp complex along with four hexafluoridophosphate counteranions. The FeCp ...

Trojan horse refers to the artifact horse-shaped and made of wood, used as a ruse by the Greeks to enter the fortified city of Troy.. Its expression takes precedence in the years 1300 BC, in an episode of the Trojan War, described by Homer in the Iliad and by Virgil in Aeneid.. The end of the war between Greeks and Trojans occurred from one of the best known incursions into the enemy territory, led by Ulysses who sent the Epeo artist to build an immense wooden horse to be offered to Athens and Poseidon, and this was accepted by Troy as a symbol of peace, convinced by Sinon, cousin of Odysseus.. To the great surprise of the Trojans, the horse contained within its structure Greek soldiers. Late at night, Sinon opened the horse and the Greeks took the city, unscrupulously killed guards, women, men, elders, and raped women. Thus, the city fell to Hellenic troops, ending ten years of conflict.. In consideration of the above, the expression Trojan horse has become popular, seen as a paremia that ...

Angew. Chem. Int. Ed. 2018, 57, 3825-3829.. In this contribution, we show that the transformation of a neutral bismuth amide into a cationic species results in a dramatic change in reactivity: the cationic bismuth amide undergoes a stepwise double CH-activation of the (NPh2)- ligand. The product of the first and the second CH activation was isolated and fully characterized. The mechanism of the CH activations was investigated by DFT calculations (backed up by experimental observations). Thus, the second step of the reaction proceeds via an electrophilic aromatic substitution, which is unprecedented in this context. The CH-activated positions can be functionalized selectively in simple one-pot-protocols, generating new routes to mono- and di-substituted aryl amines.. ...

A team of researchers have recently brought a Trojan horse antibody strategy to life that preliminary results have shown potential for combating a whole scope of filoviruses. The idea in this therapeutic method is to ultimately attack the cleaved glycoprotein in the lysosome and/or the NPC1 receptor in the lysosomal membrane to block the entry of viral genetic material into the cell, by bypassing the obvious obstacle that the lysosome is a closed off compartment within the cell. The Trojan horse title to this therapy describes how the researchers are utilizing the virus itself to deliver the aforementioned antibodies to the lysosome. This is done by coupling the cleaved GP or NPC1 targeting antibody to an antibody targeting a binding site (epitope) broadly conserved across filoviruses in the uncleaved version of the glycoprotein. Using a well-known dual variable domain strategy, DVD-Ig, this coupling of antibodies can be achieved (A.Z. Wec et al., 2016). In a simple sense, this Trojan ...

The synthesis of indaphyrins, novel meso-tetraarylsecochlorin-derived chromophores incorporating o-phenyl-to-beta-linkages, is described. Oxidative diol cleavage of meso-tetraaryl-2,3-dihydroxy-2,3-chlorins results in the formation of a secochlorin bisaldehyde. Depending on the reaction conditions during the ring cleavage reaction, one or two of the aldehyde groups react with the adjacent o-phenyl positions, leading to an intramolecular electrophilic aromatic substitution of the o-phenyl proton, and the establishment of a direct o-phenyl-to-beta-linkage. The initially formed carbinol is spontaneously oxidized to the corresponding ketone. This modification forces the aryl groups into co-planarity with the macrocycle, allowing for interactions between the pi-electrons of the aryl groups, the ketone linkage, and those of the chromophore, resulting in a significant electronic modulation of the porphyrinic pi-system. The UV-vis spectroscopic properties of the free base, CuII, NiII, and ZnII indaphyrins are
Researchers have been engineering nanoparticles to ferry toxic medicines into tumor cells before they release their cargo. After many years of studies with cell cultures and animals, nearly a dozen nanoparticle-based drugs are in clinical trials, most of which aim at treating or diagnosing cancer. Many other compounds are progressing through preclinical studies and are nearing human trials. Although it will require several more years of testing to determine whether the compounds are safe and effective, researchers are optimistic that the results will be positive. That would be welcome news in the fight against cancer. ...

My friend Melody was along for the whole ride, and many of her suggestions are what made this thing so awesome. While I was baking the pieces, she pulled out a toy horse cookie cutter and said that we had to make a Trojan horse. Anyone who knows me knows that I am a HUGE nerd about the Trojan war, so how could I not make one after she pointed it out? I put a little platform between the two horse cookies and loaded it up with little men. Theres even a ladder on the back for them to climb ...

Oxford University researchers have found that human cells use viruses as Trojan horses, transporting a messenger that encourages the immune system to fight the very virus that carries it. The discovery could have implications for the design of new vaccines.
