Abstract

NEW MATERIAL:Carboxylic acids of formula I(A is alkenylene, alkadienylene substituted with carboxyls; R2 is carboxyl, alkyl arbitrarily substituted with carboxyl; n is 0W3; R is carboxyl, alkyl, alkenyl) and their salts.
EXAMPLE: Trans-1-(3-Carboxyphenyl)-4-phenyl-1, 3-butadiene-1-carboxylic acid.
USE: Agent for accelerating or normalizing immune state, antitumor agent or liver function improver.
PREPARATION: The reaction of a compound of formula II(R1 is bond, alkylene, alkenylene) with another compound of formula III(m is 1W3), its salt or anhydride gives the compound of formula I or its salt. The reaction is conducted in the presence of a base, when necessary, in a solvent of acetic acid or the like.
