摘要

New 2-(1-Piperazinyl)-and 2-(hexahydro-1H-1, 4-diazepin-1-yl) benzothiazoles were prepared and tested as H1-and H3-receptor antagonists. A number of compounds showed weak H1-antagonistic activity, with pA2 values ranging from 5.5 to 6.1. The simple alkyl substituted, 2-[1-(4-methyl and 4-ethyl) piperazinyl] analogues show increasing, moderate H3-antagonistic activity (pA2= 6.0, and pA2= 7.0). The compounds with 4-phenylalkyl ...
