摘要
2-Amino-4-azaindoles have been identified as a structurally novel class of BKCa channel openers. Their synthesis from 2-chloro-3-nitropyridine is described together with their in vitro properties assessed by Rb-86(+) efflux and whole-cell patch-clamp assays using HEK293 cells stably transfected with the BKCa alpha subunit. In vitro functional characterization of BKCa channel opening activity was also assessed by measurement of relaxation of smooth muscle tissue strips obtained from Landrace pig bladders. The preliminary SAR data indicate the importance of steric bulk around the 2-amino substituent. (C) 2003 Elsevier Science Ltd. All rights reserved.
