Synthesis, pharmacological evaluation and docking studies of pyrrole structure-based CB 2 receptor antagonists
摘要:
During the last years, there has been a continuous interest in the development of cannabinoid receptor ligands that may serve as therapeutic agents and/or as experimental tools. This prompted us to design and synthesize analogues of the CB2 receptor antagonist N-fenchyl-5-(4-chloro-3-methyl-phenyl)-1-(4-methyl-benzyl)-1H-pyrazole-3-carboxamide (SR144528). The structural modifications involved the bioisosteric replacement of the pyrazole ring by a pyrrole ring and variations on the amine carbamoyl substituents. Two of these compounds, the fenchyl pyrrole analogue 6 and the myrtanyl derivative 10, showed high affinity (K-i in the low nM range) and selectivity for the CB2 receptor and both resulted to be antagonists/inverse agonists in [S-35]-GTP gamma S binding analysis and in an in vitro CB2 receptor bioassay. Cannabinoid receptor binding data of the series allowed identifying steric constraints within the CB2 binding pocket using a study of Van der Waals' volume maps. Glide docking studies revealed that all docked compounds bind in the same region of the CB2 receptor inactive state model. (C) 2015 Elsevier Masson SAS. All rights reserved.

The present invention relates generally to amide group containing pharmaceutical agents, and in particular, to amide containing heterobicyclic metalloprotease inhibitor compounds. More particularly, the present invention provides a new class of heterobicyclic MMP-13 inhibiting and MMP-3 inhibiting compounds, that exhibit an increased potency in relation to currently known MMP-13 and MMP-3 inhibitors.
