title: Synthesis and analgesic activity of some quinazoline analogs of anpirtoline.
abstract: New condensed derivatives of anpirtoline, in which the pyridine ring is replaced with quinoline, quinazoline, 7-chloroquinoline, and 7-chloroquinazoline nuclei, have been synthesized. Their receptor binding profiles (5-HT1A, 5-HT1B) and analgesic activity (hot plate, acetic acid induced writhing) have been studied. The analgesic activity of compounds 4e-4g, and 4l are at least comparable to that of clinically used drugs flupirtine and tramadol under the same conditions.
