Discovery and optimization of pyrazole amides as antagonists of CCR1
摘要:
A HTS screen for CCR1 antagonists afforded a novel sub-micromolar hit 5 containing a pyrazole core. In this report the design, optimization, and SAR of novel CCR1 antagonists based on a pyrazole core motif is presented. Optimization led to the advanced candidate compounds (S)-16q and (S)-16r with 250-fold improved CCR1 potency, excellent off-target selectivity and attractive drug-like properties.
A simple, efficient and three component one-pot synthesis of 1,4,5-trisubstitutedpyrazoles by condensation of β-dicarbonyls, N,N-dimethylformamide dimethyl acetal (DMFDMA) and hydrazine derivatives in 2,2,2-trifluoroethanol without using any catalyst and activation, is described.
