SAR-Based Optimization of a 4-Quinoline Carboxylic Acid Analogue with Potent Antiviral Activity
摘要:
It is established that drugs targeting viral proteins are at risk of generating resistant strains. However, drugs targeting host factors can potentially avoid this problem. Herein, we report structure-ctivity relationship studies leading to the discovery of a very potent lead compound 6-fluoro-2-(5-isopropyl-2-methyl-4-phenoxyphenyl) quinoline -4-carboxylic acid (C44) that inhibits human dihydroorotate dehydrogenase (DHODH) with an IC50 of 1 nM and viral replication of VSV and WSN-Influenza with an EC50 of 2 nM and 41 nM. We also solved the X-ray structure of human DHODH bound to C44, providing structural insight into the potent inhibition of biaryl ether analogues of brequinar.
tyrosine kinase) inhibitors are the most promising drugs for the treatment of hematologicaltumors. A high selectivity of BTK inhibitors ensures reduced side effects from off-targeting. Accordingly, here, based on Zanubrutinib, we designed and synthesized a new range of imidazopyrazole-3-carboxamide derivatives as novel BTK inhibitors that retained the amide group for improved selectivity. These compounds

A method for preparing substituted phenoxyphenols which are useful in the preparation of herbicidal (phenoxyphenoxy)propionates is disclosed. The process involves the oxidation of substituted phenoxyphenones to the corresponding phenoxyphenyl esters and their conversion to the desired phenoxyphenol. Novel intermediates for the process are similarly disclosed.

Pyrazole-5-carboxamides, novel inhibitors of receptor for advanced glycation end products (RAGE)
In an effort to develop novel inhibitors of receptor for advanced glycation end products (RAGE) for the treatment of Alzheimer's disease, a series of pyrazole-5-carboxamides were designed, synthesized and biologically evaluated. Analyses of the extensive structure activity relationship (SAR) led us to identify a 4-fluorophenoxy analog (40) that exhibited improved in vitro RAGE inhibitory activity and more favorable aqueous solubility than the parent 2-aminopyrimidine, 1. Surface plasmon resonance (SPR) and molecular docking study strongly supported the RAGE inhibitory activity of pyrazole-5-carboxamides. The brain A beta-lowering effect of 40 is also described.
