Diclofenac (DCF) is the frequently detected non-steroidal pharmaceuticals in the aquatic environment. In this study, the degradation of DCF was evaluated by UV-254nm activated persulfate (UV/PS). The degradation of DCF followed the pseudo first-order kinetics pattern. The degradation rate constant (kobs) was accelerated by UV/PS compared to UV alone and PS alone. Increasing the initial PS dosage or solution pH significantly enhanced the degradation efficiency. Presence of various natural water constituents had different effects on DCF degradation, with an enhancement or inhibition in the presence of inorganic anions (HCO3(-) or Cl(-)) and a significant inhibition in the presence of NOM...

Samuel S Pendergraft, Hooman Sadri-Ardekani, Anthony Atala, Colin E Bishop
Existing methods for evaluating the potential gonadotoxicity of environmental agents and pharmaceutical compounds rely heavily on animal studies. The current gold standard in vivo functional assays in animals are limited in their human predictive capacity. In addition, existing human two-dimensional in vitro models of testicular toxicity do not accurately reflect the in vivo situation. A more reliable testicular in vitro model system is needed to better assess the gonadotoxic potential of drugs prior to progression into clinical trials...

Extemporaneous drug formulation is essential to provide optimal pharmaceutical care to veterinary patients. The need for this is exacerbated by the fact that commercially produced veterinary-specific products, without a human indication, require specialty veterinary manufacturing facilities and a new animal drug application process to gain marketing approval. This study examined the prescription patterns of extemporaneously compounded veterinary preparations in the compounding department at a large independent community pharmacy...

Mark G Klang, LaVonn A Williams
To properly determine the accuracy of a pharmaceutical product or compounded preparation, tests must be designed specifically for that evaluation. The procedures selected must be verified through a process referred to as method validation, an integral part of any good analytical practice. The results from a method validation procedure can be used to judge the quality, reliability, and consistency of analytical results. The purpose of this article is to deliver the message of the importance of validation of a pharmaceutical product or compounded preparation and to briefly discuss the results of a lack of such validation...

Historically, compounding has been always an integral part of pharmacy. Medications were prepared by pharmacists for individual patients and compounding was the only source of drugs before mass production by pharmaceutical companies. This trend started diminishing around the middle of the 20th century due to more drugs being produced by mass manufacturers. Shortly after, clinical pharmacy was introduced and many schools of pharmacy reorganized their curricula to address that change. As a result, many compounding courses have been removed and emphasis was shifted towards clinical classes...

Induced pluripotent stem cells (iPSCs) have an extensive application in regenerative medicine, pharmaceutical discovery, and basic research. With the recent derivation of rat iPSCs, it is now feasible to apply genetic manipulation in this species. But such tools do not yet exist for many rat strains, especially for disease model rat. The Sprague Dawley (SD) rat is an inbred disease model for hypertension, nephropathy, pulmonary hypertension, depression, and alcohol consumption. In this study, the SD rat iPSCs were generated using lentiviral method...

Halogenated natural products constitute diverse and promising feedstock for molecular pharmaceuticals. However, their solution-structure elucidation by NMR presents several challenges, including the lack of fast methods to compute (13)C chemical shifts for carbons bearing heavy atoms. We show that parametric corrections to DFT-computed chemical shifts in conjunction with rff-computed spin-spin coupling constants allow for fast and reliable screening of a large number of reported halogenated natural products, resulting in expedient structure validation or revision...

Vanja Polic, Karine Auclair
Human cytochrome P450 3A4 (CYP3A4) is responsible for the metabolism of the majority of drugs. As such, it is implicated in many adverse drug-drug and food-drug interactions, and is of significant interest to the pharmaceutical industry. This enzyme is known to simultaneously bind multiple ligands and display atypical enzyme kinetics, suggestive of allostery and cooperativity. As well, evidence of a postulated peripheral allosteric binding site has provoked debate around its significance and location. We report the use of bioconjugation to study the significance of substrate binding at the proposed allosteric site and its effect on CYP3A4 activity...

Filamentous fungi of the Ascomycota phylum are known to contain a family of conserved conidiation regulating proteins with distinctive velvet domains. In Aspergilli, this velvet family includes four proteins, VeA, VelB, VelC and VosA, and is involved in conidiation and secondary metabolism along with a global regulator LaeA. In A. terreus, the overexpression of LaeA has been observed to increase the biogenesis of the pharmaceutically-important secondary metabolite, lovastatin, while the role of the velvet family has not been studied...

"Amelogenesis imperfecta" (AI) describes a group of inherited diseases of dental enamel that have major clinical impact. Here, we identify the aetiology driving AI in mice carrying a p.S55I mutation in enamelin; one of the most commonly mutated proteins underlying AI in humans. Our data indicate that the mutation inhibits the ameloblast secretory pathway leading to ER stress and an activated unfolded protein response (UPR). Initially, with the support of the UPR acting in pro-survival mode, Enamp.S55I heterozygous mice secreted structurally normal enamel...
