Over many years, the pharmaceutical industry has developed a highly successful model for making new medicines. Currently, there are an estimated 13,000 prescription drugs on the market. However, the model that has served the sector so well for so long is now breaking down. Lack of productivity in the laboratory, the imminent expiry of patents for numerous best selling products, intense competition and a more demanding marketplace, are all signs of a need for a new approach to drug discovery. Consequently, some pharmaceutical executives may feel that they are managing a previously prestigous team, which now find themselves in the relegation zone, and cannot continue under the same model. This article suggests that radical transformation of the business at every level is the only key to long-term success.

Enzymatic asymmetric synthesis of l-phenylglycine by amino acid dehydrogenases has potential for industrial applications; however, this is hindered by their low catalytic efficiency toward high-concentration substrates. We identified and characterized a novel leucine dehydrogenase (LeuDH) with a high catalytic efficiency for benzoylformic acid via directed metagenomic approaches. Further, we obtained a triple-point mutant LeuDH-EER (D332E/G333E/L334R) with improved stability and catalytic efficiency through the rational design of distal loop 13.

The use of olefins in the construction of cyclic compounds represents a powerful strategy for advancing the pharmaceutical industry. Photocycloaddition has attracted significant interest from chemists due to its ability to exploit simple and readily available olefins along with their reaction patterns under mild conditions. Moreover, the sustainable and versatile pathways for generating highly reactive intermediates can greatly enrich both substrate diversity and reaction patterns.

Unlabelled: Pile fermentation plays a crucial role in the formation of the unique flavor of Liupao tea, which can effectively reduce the bitterness of the tea and promote the formation of red tea soup. In this study, the non-volatiles changes of Liupao tea during pile fermentation processing were fully analyzed by UPLC-QTOF-MS/MS. A total of 271 metabolites with significant differences were identified in Liupao tea during pile fermentation( < 0.

Residual antimicrobial agents in wastewater and solid waste from antimicrobial manufacturing facilities can potentially contaminate environments. The World Health Organization has established technical guidelines for managing antimicrobial resistance (AMR) in pharmaceutical wastewater and solid waste. However, the scarcity of publicly available data on antimicrobial manufacturing processes impedes the development of effective mitigation strategies.

Unlabelled: Potato peels are one of the most under-utilized wastes which can be highly beneficial to mankind. The red potato peel powder was prepared by using tray drying and vacuum-oven drying method. The proximate analysis of red potato peel powder was conducted followed by its characterization which includes FT-IR, XRD, TGA, DSC, and SEM.
