A series of N-(2-cyano-substituted-phenyl)oxamates was prepared by acylation of the appropriate anthranilonitrile with ethyloxalyl chloride.Hydrolysis with sodium hydroxide gave the corresponding oxamic acid sodium salts.These compounds were extremely potent when tested in the rat passive cutaneous anaphylaxis (PCA assay either by the ip or the po route of administration).One of the sodium salts, oxoacetic acid sodium salt (11a, Wy-41 195), has ED50 value of 0.07 mg/kg po and has been selected for further evaluation.

Anti-allergic agents of aromatic oxamic acid derivation present the following formula: STR1 in which A is a member selected from the group consisting of α-naphthyl, β-napthtyl, phenyl, 2,6-di-chlorophenyl, and substituted phenyl moieties containing from one to three substituents in any of the 2,3,4 and 5 positions of the phenyl ring, independently selected from the group consisting of lower alkyl, lower alkylthio, lower alkylsulfinyl, lower alkoxy, hydroxy (lower)alkoxy, 2-(oxalyloxy) ethoxy, benzyloxy, N-mono- and di-lower alkylamino(lower)alkoxy, halo, sulfamyl, polyhalo(lower)alkyl, carbamyl, N-lower alkylcarbamyl, nitro, mono and di lower alkylamino, carboxy, lower alkylcarbonyl, carb(lower)alkoxy, phenoxy(lower)alkoxy, and oxalamidophenoxy radicals; and pharmaceutically acceptable salts thereof.
