A New Type of Cytotoxic Immunosuppressive Agent: 3-Acetyl-5-(4-fluorobenzylidene)4-hydroxy-2-oxo-2:5-dihydrothiophen

Abstract

DURING the past 3 years we have been investigating the biological properties of a series of thiophens of tho following general formula (I): in which R is an alkyl or alkoxy group and the substituent X is an electron-withdrawing group such as halogen or nitro. These investigations resulted from the observation that the compound I.C.I. 45,514 (I, R = ethoxy, X = H) prevented the development of secondary inflamed lesions in rats injected into the foot-pad with a fine suspension of dead tubercle bacilli in liquid paraffin. The use of this syndrome for evaluating chemotherapeutic agents has already been described1,2.
