Title: Solution Stability - Plasma, Gastrointestinal, Bioassay. VOLUME: 9 ISSUE: 9. Author(s):Li Di and Edward H. Kerns. Affiliation:Wyeth Research, Princeton, NJ 08543-8000, USA.. Keywords:Plasma stability, solution stability, simulated gastro-intestinal fluids, stability-ph profile, high throughput, drug discovery, HPLC, LC-MS. Abstract: Solution stability of drug candidates in plasma, gastrointestinal fluids and bioassays is important in order to achieve low clearance, good oral bioavailability and have robust SAR. Screening of solution stability early in drug discovery can avoid pursuing hits with high risk of instability, prioritize chemical series, guide structural modification, and enhance the chance of project success. The conditions of solution stability methods are critical in generating relevant data and include: test compound concentration, enzyme source and preparation, limits of solubility, cosolvent, plasma protein binding effect, detection techniques (LC-UV vs. LC-MS), and what ...

TY - JOUR. T1 - Criteria for Judging the Quality of a Publication on Physicochemical Stability of Ready to Use Injectable Drugs. AU - Hecq, Jean-Daniel. AU - Bihin, Benoit. AU - Jamart, Jacques. AU - Galanti, Laurence. PY - 2017/8/8. Y1 - 2017/8/8. N2 - In hospitals, a major part of the drugs is administered via the intravenous route. When one wants to evaluate or know the stability of a drug in solution, it is necessary to know several physico-chemical parameters. Several reference works are available to help the hospital pharmacist with this research. However, reading these different sources can make you discover conflicting data. It is therefore necessary at this time to obtain the publications with contradictory results and to read them again. Seven criteria have been identified for judging the quality of a publication on physicochemical stability: full description of equipment, methods and analytical conditions of molecules studied; complete description of the procedures used to validate ...
TY - JOUR. T1 - Stabilization of eptifibatide by cosolvents. AU - Zhao, Luwei. AU - Yalkowsky, Samuel H. PY - 2001/5/7. Y1 - 2001/5/7. N2 - Eptifibatide is a potent and highly specific inhibitor of platelet receptor glycoprotein IIb/IIIa and is indicated in the treatment of acute coronary syndrome. The commercial product Integrilin® (eptifibatide) Injection requires a cold/refrigerator storage condition. In an effort to improve the drug stability for room temperature storage and transportation, this study proposed a semi-aqueous formulation that contains 2 mg/ml eptifibatide, 10% ethanol, 40% propylene glycol and 50% 0.025 M citrate buffer. The stability study was conducted in the pH range 4.25-6.25 under accelerated temperatures: 48, 60, 72.5°C. The results indicate that the proposed semi-aqueous vehicles substantially increased the drug stability in comparison with aqueous vehicles. The predicted drug shelf-life T90 at 25°C shows that an almost twofold increase can be achieved by ...

Author: Trissel Lawrence A, Zhang Yanping, Year: 2004, Abstract: A three-drug injection mixture of alprostadil 12.5 µg/mL, papaverine hydrochloride 4.5 mg/mL and phentolamine mesylate 0.125 mg/mL in bacteriostatic 0.9% sodium chloride injection was evaluated for stability at 23°C, 4°C, -20°C and -70°C. The injection remained clear and colorless in all samples throughout the study. Chemical stability testing was performed using stability-indicating high-performance liquid chromatographic analysis. Alprostadil was the least stable of the drug components
Electron transfer plays a vital role in drug metabolism and underlying toxicity mechanisms. Currently, pharmaceutical research relies on pharmacokinetics (PK) and absorption, distribution, metabolism, elimination and toxicity (ADMET) measurements to understand and predict drug reactions in the body. Metabolic stability (and toxicity) prediction in the early phases of the drug discovery and development process is key in identifying a suitable lead compound for optimisation. Voltammetric methods have the potential to overcome the significant barrier of new drug failure rates, by giving insight into phase I metabolism events which can have a direct bearing on the stability and toxicity of the parent drug being dosed. Herein, we report for the first time a data-mining investigation into the voltammetric behaviour of reported drug molecules and their correlation with metabolic stability (indirectly measured via t½), as a potential predictor of drug stability/toxicity in vivo. We observed an inverse

Prior to joining the Department of Pharmaceutical Chemistry at The University of Kansas as a Distinguished Professor in 2017, I spent 30+ years working in the Pharmaceutical Industry. I have extensive experience in physicochemical characterization and preclinical assessment of new chemical entities (NCE), including proteins, peptides, oligonucleotides, protein drug conjugates, prodrugs, and other small molecule based therapeutics. I have been directly involved in the Discovery process with chemical lead selection, chemical lead optimization, and drug candidate selection for transition into clinical development. Those preclinical experiences include drug delivery research for both parenteral and oral dosage form design, with particular emphasis on designing specialized formulation strategies to overcome poor drug stability and poor aqueous solubility, with the ultimate goal of enhancing developability and commercialization. I have extensive experience, and resulting patents, on the generation of ...
Temperature is one of the primary factors affecting drug stability. The rate constant/ temperature relationship has traditionally been described by the Arrhenius equation,. where Ea is the activation energy and A is the frequency factor. This equation is a variant of the equation describing the effect of temperature on equilibrium processes that was developed by vant Hoff in 1887. Arrhenius applied his equation to various reaction processes.298 Comparison of the empirical Arrhenius equation to the Eyring equation, Eq. (2.7), shows some similarities and some differences. The frequency factor A in the Arrhenius equation corresponds to the product of the universal collision and entropy terms in Eq. (2.7) while the Ea term in Eq. (2.70) is related to the enthalpy term in Eq. (2.7).299 Because aplot of the logarithm of k against the reciprocal of absolute temperature generally yields a linear relationship (Arrhenius plots), the frequency factor and activation energy are regarded as independent of ...
Novel biodegradable, non-toxic nanoparticles that act as stabilizing excipients with a wide variety of suspension drug candidates including polar & non-polar drug particles, bio-macromolecules (proteins/peptides), gene therapies (DNA/siRNA) as well as amorphous and crystalline therapeutics have been developed which provide a platform for improving insoluble drug delivery. A large variety of approaches have been developed at WSU aimed at increasing the effectiveness of pressurized meter-dose inhalers (pMDIs) through improved aerosol characteristics, drug stability and reduced biotoxicity. Dr. Sandro da Rocha has been researching novel oral inhalation formulations and methods relevant in numerous pulmonary drug delivery markets including asthma, COPD, and lung cancer. Novel nanoparticle-based drug compositions have been shown to greatly improve and expand therapeutic drug delivery to the lungs through pressurized meter-dose inhalers (pMDIs). Some of these technologies can also be applied to dry ...

There is an increasing demand for biomarkers in clinical treatment trials to demonstrate target engagement and to support disease modification claims. To be able to detect treatment related effects, a prerequisite is that the levels of the biomarker are stable over time or that the change over time is known. In the present study, the stability of alpha- and beta-cleaved soluble amyloid-beta protein precursor (sA beta PP alpha and sA beta PP beta), A beta(1-40) together with the phosphorylated form of neurofilament heavy/medium (pNfH/M) in cerebrospinal fluid (CSF) was analyzed in a cohort of 51 patients with Alzheimers disease. In addition, the stability of A beta(1-40), beta(1-42), and sA beta PP beta in plasma was explored. Plasma and CSF was sampled at baseline and after 6-months follow up, and all patients were on stable treatment with acetylcholinesterase inhibitors. During this 6-month longitudinal follow-up, we saw a small, but consistent and statistically significant increase in CSF ...

Since over 40 enzymes will be investigated for their mRNA abundance, processing, and degradation kinetics, the less tedious and more accurate Next Generation Sequencing of the entire mRNA repertoire of the cell is employed. To optimise the proportion of useful sequence, while including RNA fragments that are products of of degradation, rRNA is depleted using the eukaryotic Ribominus kit (Ambion). Two biological replicates are treated with Sinefungin and Actinomycin D to inhibit RNA processing and transcription, for different time periods. RNA is collected before treatment, 5 min after the addition of Sinefungin, 5 min after addition of ActD (+Sin), then 10 min after, 20, 30, 60 and 120 min. The samples are sequenced using the Illumina standard protocol, and the sequenced reads are aligned to the reference genome TREU927, and the number of reads aligned to each ORF are determined. ...

As prepared for delivery Governor Liebscher, distinguished guests, ladies and gentlemen, good morning to you all. It is a great pleasure for me to be here with you today, at the 33rd Economics Conference hosted by the Austrian National Bank-and, I must add, it is a delight to visit again this beautiful and historic city. I have been asked by the conference organizers to speak to the issue of financial sector stability and the IMFs work in this area-and I will seek to stay close to this topic in my remarks.. Financial sector stability has been described as the issue that central bankers worry about when they are not worrying about price stability. Experience regularly reminds us that there is a solid basis for this worry. The East Asian crisis during the late 1990s provided a striking example of how financial sector weaknesses can trigger economic turmoil and amplify the effects of adverse shocks on the economy, with severe economic and social consequences. Several industrial countries, ...

CCMB maintains and stocks about 6500 biochemicals for the ongoing research activities of the laboratory. The facility has a cold room (+4°C), two +4°C refrigerators, eight deep freezers (-20°C) and two ultra deep freezers (-70°C) for storage of chemicals as per the recommended storage conditions. However, the chemicals stable at room temperature are kept in a room (98 sq.mtrs plinth area) where temperature is maintained at 28°C. The stocks of fine biochemicals include amino acids, proteins, enzymes, purification kits and buffer reagents. In addition, stocks of restriction enzymes, immunology research kits for purification and detection of recombinant proteins, reagents for protein electrophoresis, PCR, RTPCR, DNA sequencing and synthesis and buffers, tissue culture ware, medium and medium supplements, gel electrophoresis and column chromatography materials, chemicals related to proteomics, and microarray analysis are also kept in the centralized facility. The requirement for these chemicals ...
Fluorescent labelling of monoclonal antibodies (mAbs) is classically performed by chemical bioconjugation methods. The most frequent labelling technique to generate antibody-fluorophore conjugates (AFCs) involves the bioconjugation onto the mAb lysines of a dye bearing an N-hydroxysuccinimide ester or an isothiocyanate group. However, discrepancies between labelling experiments or kits can be observed, related to reproducibility issues, alteration of antigen binding, or mAb properties. The lack of information on labelling kits and the incomplete characterization of the obtained labelled mAbs largely contribute to these issues. In this work, we generated eight AFCs through either lysine or interchain cysteine cross-linking bioconjugation of green-emitting fluorophores (fluorescein or BODIPY) onto either trastuzumab or rituximab. This strategy allowed us to study the influence of fluorophore solubility, bioconjugation technology, and antibody nature on two known labelling procedures. The structures of

Most of our products are stable at room temperature for many days, so in all likelihood the product will still work just fine. To be on the safe side, we recommend performing a small scale positive control experiment to confirm that the product still works for your application before processing a large number of samples or precious samples.. One exception that we are aware of is GelGreen™, which is more sensitive to light exposure than most of our other fluorescent dyes. If GelGreen™ is exposed to ambient light for a prolonged period of time (days to weeks), its color will change from dark orange to brick red. If this occurs, the GelGreen will no longer work for gel staining.. ...
What Chirumbolo et al. are proposing is that a histamine molecule in water can cause the water molecules to arrange themselves around it in a kind of quasi-crystalline cluster -- a cluster having the same chemical and biological properties as the histamine itself. Further, the clusters are self-replicating: they can catalyse the formation of copies of themselves across multiple stages of dilution and succussion. This is a whole new polymorph of H2O, more stable at room temperature than liquid water ...
Storage: Lyophilized peptides although stable at room temperature for 3 months, should be stored desiccated below -18°C. Upon reconstitution of the peptide it should be stored at 4°C between 2-21 days and for future use below -18°C.. HGH Frag 176-191 is a fragment of the HGH peptide. Scientists found that if they truncated the peptide at the C terminal region they could isolate the fat loss attributes associated with HGH. Taking this fragment from HGH, including the peptide bonds from 176-191, they found they had developed a peptide that regulated fat loss 12.5 times better than regular HGH.. Introduction:. There is no question as to why bodybuilders of the modern era utilize human growth hormone. Its ability to regulate fat loss, pack on size and increase IGF-1 levels is just a few of the many attributes that many seek. HGH Frag 171-191 was developed so that bodybuilders and athletes not looking for the growth properties from HGH could still reap all the results of its amazing fat loss ...

The reaction is believed to proceed by the indicated conversion of a lithium carboxylate to the dilithium salt18 which is stable at room temperature in the absence of proton-donating solvents or reactants. However, the rapidity with which this dilithium salt is decomposed to a ketone in the presence of proton donors, accompanied by the rapidity of the subsequent reaction of the ketone with more methyllithium, can lead to a common side reaction in which an alkyldimethyl carbinol is formed. Both of the aforementioned reactions appear to be fast compared with 0.01 second usually required to disperse components with the conventional mixing techniques. This side reaction can be almost entirely avoided by taking precautions to minimize the possibility that high local concentrations of the geminal dialkoxide and the lithium reagent are present when a proton donor is added during either the reaction or the subsequent quenching. It is frequently possible to obtain only relatively small amounts of the ...

About 10% of the study population showed excessive levels of perceived fall risk and were classified as anxious. Despite their low physiological fall risk, almost 40% of the anxious group experienced multiple or injurious falls during the one year follow-up. In keeping with previous studies, we anticipated that self imposed restriction on levels of physical activity would contribute to overall risk in this group.5 13 However, there was no indication of lower levels of activity, so other reasons need to be explored as to why anxious participants fell more than vigorous participants during follow-up.. It is possible that the anxious group had a residual physiological fall risk not encompassed by the physiological profile assessment. Thus, although the groups low physiological profile assessment score indicated that the integrity of individual sensorimotor components was adequate, their relatively poor performance on the coordinated stability test suggests that the integration of each of these ...

Previous studies have shown that equine SAA is more stable at room temperature than refrigerated. A small study at Cornell University confirmed this finding. Two equine samples with high values of 481 and 177 ug/ml showed a 2-3% decrease in concentration at 4ºC with storage for 24 hours versus a 3-5% decrease at room temperature. With storage for 72 hours, the drop at 4ºC was greater than at room temperature (7% versus 3-6% at 48 hours and 8-9% versus 2-4% at 72 hours). Very high values (,60 ug/dL) were still abnormal after 10 days of storage at either temperature (Hillstrom et al 2010). SAA concentrations are stable frozen (-20ºC), thus it is recommended that for storage ,24 hours, the samples should be frozen and shipped ensuring that they remain frozen. If freezing is not an option, then the samples should be maintained at room temperature. This also suggests that mildly increased concentrations may drop to within reference intervals (,20 ug/mL in horses) with storage. Stability is unknown ...

OPAT is used for treating a wide range of infections, including skin and soft tissue infections, osteoarticular infections, bacteraemia, endocarditis and complex intra-abdominal and urinary tract infections, even in presence of multiresistant microorganisms. Correct choice of antimicrobial agent and adequate patient selection are crucial for reaching therapeutic success and avoiding readmissions, treatment prolongation or treatment-related toxicity. The optimal antimicrobial for OPAT must be highly effective, have a long half-life and an adequate spectrum of action. Ceftriaxone and teicoplanin are currently the most prescribed antibiotics for OPAT, though daptomycin and ertapenem are also on the rise, due to their high efficiency, safety and wide spectrum of action. Antibiotics that are stable at room temperature can be administered through a continuous perfusion, though self-administration is preferable although it requires training of the patient or the caregiver. Factors that are most ...

If outfitted with molecular handles at the ends, it can also be twisted to alter its band gap. With a 90-degree end-to-end rotation, it becomes a magnetic semiconductor.. * Carbyne chains can take on side molecules that may make the chains suitable for energy storage.. * The material is stable at room temperature, largely resisting crosslinks with nearby chains.. Thats a remarkable set of qualities for a simple string of carbon atoms, Yakobson said.. You could look at it as an ultimately thin graphene ribbon, reduced to just one atom, or an ultimately thin nanotube, he said. It could be useful for nanomechanical systems, in spintronic devices, as sensors, as strong and light materials for mechanical applications or for energy storage.. Regardless of the applications, he said, academically, its very exciting to know the strongest possible assembly of atoms.. Based on the calculations, he said carbyne might be the highest energy state for stable carbon. People usually look for what is ...
Prediction of shelf life is facilitated if the data include frequent intermediate stations (in line with the CPMP/ICH recommendations), are derived from several batches, consider a range of conditions, are of high precision, include analysis for breakdown products, and consider the physical properties of the formulation.. The Note for guidance on Evaluation of Stability Data (CPMP/ICH/420/02) provides detailed guidance on evaluation of the data from formal stability studies. The guideline presumes that the required amount of minimum data are available, as outlined under Section 9.4 Minimum data requirements.. For products intended for storage in a freezer no extrapolation beyond the period covered by the long term data is permitted (and testing of a single batch at an appropriate elevated temperature should also be conducted to address the effect of short term excursions outside the proposed label storage condition, such as during shipping or handling).. For other products, the assessment ...

Louis Roux from LifeAssay Diagnostics (Pty) Ltd. in South Africa, in collaboration with PATH, will develop an easy-to-use, low-cost, strip test for pregnant women in developing countries to detect the onset of proteinuria, which indicates a highly increased risk of preeclampsia/eclampsia. Preeclampsia/eclampsia is a major cause of maternal death, particularly in developing countries. Onset is rapid, and so early diagnosis is crucial, particularly in remote communities where health care is not immediately available. The test measures the ratio of protein to creatinine, which is more accurate than the current protein-only version, and they will produce a low-cost version that can be locally manufactured. They will evaluate the tests performance in comparison to three similar tools on a minimum of 1100 urine samples collected from the CAP trial in South Africa. The study also includes usability and stability evaluations to inform further prototype improvements and product insert development for ...

It is known that membrane technologies may have a major role to play in the development of environmental-friendly processes, either in gas or liquid separations. In liquid separations, one of the challenging issues is to get membranes with suitable separation properties able also to survive to the exposure of liquid solvents at various temperatures. Aromatic polyimides are known to exhibit a very good stability to a great number of solvents, but their permeability are low because of their rigid carbon skeleton and of their low available free volume; so their uses are mainly limited to gas separations or to filtration processes (MF, UF). To broaden the application area of polyimides in liquid separations, we have prepared and studied the properties of a block ether aromatic copolyimide series where the ether soft block acts both as a selective and a permeable block; we describe attempts to get asymmetric polyetherimide (PEI) membranes having molecular separation properties using various experimental

The durability of swings or climbing frames also depends on the materials used and their weather resistance. Play equipment with frames of highly durable woods such as oak or redwood is more expensive and less common at DIY markets. Discounters mostly offer standard equipment made of metal or so-called pressure-treated pine, which requires more maintenance.. Before purchasing their selection, parents should feel free to thoroughly inspect the equipment and consider carefully whether the equipment suits their purposes. Solid material and good stability should rate more highly than nice bright colours. Other important factors are:. · The equipment should be free from sharp edges or sharp ...

Our son Tobias is 7 years old and has Angelmans Syndrome and is a very active boy.. We love the Pixi stroller, because it is strong and offers good stability. Tobias can climb in himself with stepping up on the footplate.. The stroller is strong and safe enough so that Tobias cannot tip it over, although he is a very lively boy!. When we go to the mall and have lunch we dont need a special chair for Tobias. The stroller is the right size to sit at the table, and Tobias cannot run away.. The Pixi stroller is excellent in the forest and on the beach, because the stroller has air tires and makes it easy to handle and push. We like also the adjustable ergonomic handlebar which is great when we have a Nanny who is not so tall.. I am happy about the durable seat cover, because Tobias can be messy. The seat cover is easy to remove and wash.. Folding is easy. We have a small car and it goes into the car easily on its side.. Our conclusion is: anytime again with the Pixi stroller!. Tobiass ...
