NEWER N-SUBSTITUTED THIADIAZOLYL/AZETIDINONYL ANTHRANILIC ACID DERIVATIVES AS POTENT ANTI- INFLAMMATORY AGENTS Authors: Nancy , SAKSHI CHAUDHARY AND ARCHANA
ABSTRACT
In the present study various 5-halo-N-amino acetylamino-(2’-substitutedarylidenyl-4’-thiazolidinonyl)-
benzoic acids (16-24) and 5-halo-N-amino acetylamino-(3’-chloro-4’-substitutedarylidenyl-
2’azetidinonyl)- benzoic acids (25-33) have been synthesized by cyclization of compounds 5-halo-N-
amino acetyl substituted arylidenyl hydrazino benzoic acids (7-15) via route-1 and route-2 respectively as
depicted in figure. The purity of the compounds was checked by TLC. Metling points were determined in
open capillaries and are uncorrected. The structure of all the synthesized compounds was characterized by
C, H, N (elemental analysis) and spectral analysis (IR, NMR). Further, the above said compounds were
also evaluated for anti-inflammatory and ulcerogenic activities along with acute toxicity. These
compounds were found to possess varying degrees of these activities. Compound 21, 5-bromo-N-amino
acetylamino-[2’-(N,N-dimethylarylidenyl)-4’-thiazolidinonyl]- benzoic acid was found to be the most
potent compound of the series, more potent than standard drug phenyl butazone, showing a protection of
55.98%, against paw edema induced by carrageenan. Most of the compounds exhibit less ulcerogenic
activity and ALD50 >1000 mg/kg p.o. except compounds 21 and 30, which possess ALD50 >2000 mg/kg
p.o.
