Synthesis and structure–analgesic activity relationships of a novel series of monospirocyclopiperazinium salts (MSPZ)
摘要:
A series of monospirocyclopiperazinium salts were designed and synthesized to search for a peripherally-acting analgesic drug with low side effects. Extensive SAR studies revealed that a suitable (NRR3)-R-2 was critical for the analgesic activity, which might be beneficial to expose the cationic nitrogen to bind to the receptor, and possibly interact with the receptor via pi-pi interaction. Introduction of substituting group on the N-4-phenyl ring could improve the activity, and the best position was the 4-position. Compound 14n showed more potent analgesic activity (63%, 20 mu M/kg, sc) and holds promise for development as a mechanically new analgesic drug. (C) 2010 Elsevier Ltd. All rights reserved.
