The activation of pregnane X receptor (PXR), a member of the nuclear receptor superfamily, can mediate potential drug-drug interactions by regulating the expression of several drug- mediated enzymes and transporters, resulting in reduced therapeutic efficacy or increased toxicity by producing reactive metabolites. Therefore, in the early stage of drug development, it is important to predict these risks using an in silico approach. We constructed a human PXR (hPXR) pharmacophore model based on known structural information of compounds that activate PXR...

Purpose. Potato fruit juice, a residue of starch industry, contains up to 2.5% [w/w] of proteins that are potentially valuable raw-materials of food, cosmetic, and pharma industries. The recovery of protein from the potato fruit juice is limited by the lack of industrially feasible concentration and separation technologies. The present research thus aimed at development of such process for the separation of active protease inhibitors from potato fruit juice. Methods. Low temperature mechanical vapor recompression evaporation was applied for concentration of potato fruit juice followed by ethanol precipitation for recovery of active proteins...

The biotech and pharma (biotech/pharma) industry is in dire need of finding ways to increase efficacy, efficiency, and affordability of its products. The information and technology industry ("tech") industry, which is an industry similarly founded on inventions and innovation, may provide some food for thought. This perspective will demonstrate the shift that biotech/pharma is already making and will propose that the industry has an opportunity to compel change by adopting some aspects of the tech industry with regards to models for technology/product development and leadership attributes...

Lornoxicam is an anti-inflammatory drug used to relieve rheumatoid arthritis pain, but the low water solubility and bitter taste of the drug present challenges for formulation as fast disintegrating tablets (FDTs). Complexation of the drug with β-cyclodextrin was initially carried out to increase the drug solubility and to mask its bitter taste. Tablets were prepared by direct compression of drug complex (DC), F-Melt, mannitol, crospovidone, and sodium starch glycolate (SSG). FDTs were characterized in terms of disintegration time (DT) and dissolution...

A doubly enteric-coated multiple-unit tablet (DET) of bisacodyl (BD) was formulated to selectively deliver the stimulant laxative to the large intestine. Solubilized BD in surfactants was adsorbed into the porous carrier and primarily coated with different combinations of pH-sensitive polymers (Eudragit S and Eudragit L) and time-dependent release polymer (Eudragit RS). BD-loaded granules were compressed into tablets and coated again with pH-sensitive polymers (Eudragit S:Eudragit L=1:1). The multiple-unit tablet was optimized with respect to the granular coating compositions (Eudragit S:Eudragit L:Eudragit RS=5:1:4) and coating level (12...

Therapeutic monoclonal antibodies (mAbs) are an important class of drugs used to treat diseases ranging from autoimmune disorders to B cell lymphomas to other rare conditions thought to be untreatable in the past. Many advances have been made in the characterization of immunoglobulins as a result of pharmaceutical companies investing in technologies that allow them to better understand mAbs during the development phase. Mass spectrometry is one of the new advancements utilized extensively by pharma to analyze mAbs, and is now beginning to be applied in the clinical laboratory setting...

Journalist David France's How to Survive A Plague is a searing firsthand account of the early years of the HIV/AIDS epidemic in New York City. AIDS activists, most of them gay men, were fighting for their lives. Researchers, politicians, public health officials, and pharma were slow to respond-or resisted outright.

BACKGROUND: Advanced stage Hodgkin's lymphoma represents a heterogeneous group of patients with different risk profiles. Data suggests that interim PET assessment during chemotherapy is superior to baseline international prognostic scoring in terms of predicting long-term treatment outcome in patients with Hodgkin's lymphoma. We therefore hypothesised that early interim PET-imaging after two courses of bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP) might be suitable for guiding treatment in patients with advanced stage Hodgkin's lymphoma...

In the context of increased pharmaceutical innovation deficits and Big Pharma blockbusters' patent expirations, this paper examines the moderating role of firms' absorptive capacity in external innovation activities of Big Pharma firms. The study indicates a rising interest of Big Pharma in acquisitions of and alliances with biotechnology companies. Unfortunately, this increased interest is not reflected in the number of new drugs generated by Big Pharma. We find that acquisitions of biotech companies have negatively affected Big Pharma firms' innovation performance on average but these acquisitions might have a positive effect at higher levels of acquiring firms' absorptive capacity...
