The limited availability of bioactive natural products for pharmaceutical studies and drug development is a problem that can be solved, in principle, by total synthesis. The potent antitumor marine natural products ecteinascidin 597 (I; R = Me) and ecteina ...
The availability of mycobacterial genome sequences has paved the way to identifying potential tuberculosis vaccine candidates in order to replace the currently used bacillus Calmette-Guérin (BCG) vaccines that show variable protective efficacy in adults. G ...
More effective therapies are urgently needed against hepatitis C virus (HCV), a major cause of viral hepatitis. We used in vitro protein expression and microfluidic affinity analysis to study RNA binding by the HCV transmembrane protein NS4B, which plays a ...
The major pathways of human pharmaceuticals into the environment are from their use by individuals either at home or under medical supervision in hospitals, and to a lesser extent by the disposal of unwanted or out of date drugs. The administered pharmaceu ...
Synthetic bioactive hydrogels have been widely recognized as key elements of emerging strategies to engineer tissues. However, the current shortage of highly specific and biocompatible methods to form and functionalize these materials hampers their wide ph ...
When 3-fluoro- and 3-chloro-1,2-didehydrobenzenes are generated in the presence of 2-(trimethylsilyl)furan, two regioisomeric cycloadducts are formed in a 1:2 ratio. However, regioselectivity can be installed by fitting one bulky trimethylsilyl group into ...
NOVELTY - Determining a receptor-ligand interaction involves repeatedly contacting a cell comprising a receptor, with a ligand, of the receptor in which the ligand has a fluorescence labeling group and binds reversibly to the receptor under conditions in w ...
The kinetics of Ultraviolet C (UV-C)-induced direct phototransformation of four representative pharmaceuticals, i.e., 17 alpha-ethinylestradiol (EE2), diclofenac, sulfa methoxazole, and iopromide, was investigated in dilute solutions of pure water buffered ...
Recombinant protein-based biologics are increasingly relevant in the pharmaceutical industry. Currently, mammalian cell-based bioprocesses are a routine manufacturing procedure for complex proteins such as recombinant antibodies, and the number of new biol ...
In the pharmaceutical industry, batch crystallization processes at production scale are not always well understood. Several factors have a significant impact on the process of crystallization, such as the physicochemical properties (solubility curve and su ...
