Benzylamide antagonists of protease activated receptor 2 with anti-inflammatory activity

Activation of protease activated receptor 2 (PAR2) has been implicated in inflammatory and metabolic disorders and its inhibition may yield novel therapeutics. Here, we report a series of PAR2 antagonists based on C-terminal capping of 5-isoxazolyl-l-cyclohexylalanine-l-isoleucine, with benzylamine analogues being effective new PAR2 antagonists. 5-Isoxazolyl-l-cyclohexylalanine-l-isoleucine-2-methoxybenzylamine (10) inhibited PAR2-, but not PAR1-, induced release of Ca2+(IC500.5 muM) in human colon cells, IL-6 and TNFalpha secretion (IC501-5 muM) from human kidney cells, and was anti-inflammatory in acute rat paw inflammation (ED505 mg/kg sc). These findings show that new benzylamide antagonists of PAR2 have anti-inflammatory activity.

Synthesis of isochalcogenazole rings by treating beta-(N,N- dimethylcarbamoylchalcogenenyl)alkenyl ketones with hydroxylamine-O-sulfonic acid

beta-(N,N-Dimethylcarbamoylselenenyl)- and beta-(N,N- dimethylcarbamoyltellurenyl)alkenyl ketones were converted into isoselenazoles and isotellurazole Te-oxides, respectively, simply by treating with hydroxylamine-O-sulfonic acid, and deoxygenation of the latter products was successfully carried out by treating with PPh3. Alternative treatment of ynone oxime tosylates with hydrochalcogenide ions or N,N- dimethylchalcogenocarbamate ions also gave the same isochalcogenazole rings. These reactions were assumed to proceed through intramolecular nucleophilic substitution on the nitrogen atom of oxime sulfonates by the attack of in situ generated chalcogen nucleophiles.

Prediction of Organic Reaction Outcomes Using Machine Learning

Computer assistance in synthesis design has existed for over 40 years, yet retrosynthesis planning software has struggled to achieve widespread adoption. One critical challenge in developing high-quality pathway suggestions is that proposed reaction steps often fail when attempted in the laboratory, despite initially seeming viable. The true measure of success for any synthesis program is whether the predicted outcome matches what is observed experimentally. We report a model framework for anticipating reaction outcomes that combines the traditional use of reaction templates with the flexibility in pattern recognition afforded by neural networks. Using 15?000 experimental reaction records from granted United States patents, a model is trained to select the major (recorded) product by ranking a self-generated list of candidates where one candidate is known to be the major product. Candidate reactions are represented using a unique edit-based representation that emphasizes the fundamental transformation from reactants to products, rather than the constituent molecules’ overall structures. In a 5-fold cross-validation, the trained model assigns the major product rank 1 in 71.8% of cases, rank ?3 in 86.7% of cases, and rank ?5 in 90.8% of cases.
