Antinociceptive Properties of Chloromaleinimides and Their Sulfonyl Derivatives.

Abstract

Antinociceptive Properties of Chloromaleinimides and Their Sulfonyl Derivatives. -A variety of new chloromaleimides [cf. (V), (IXa)] and corresponding sulfonyl derivatives [cf. (VIII), (IXb,c)] are synthesized and evaluated for their antinociceptive activities. Some of them, when intraperitoneally injected, prove to be potent and dose-related antinociceptives, being several times more active than many known reference drugs. -(WALTER, M.
