Quantitative structure-activity relationships of benzoyliminothiadiazoline derivatives as angiotensin II receptor antagonists
摘要:
Syntheses and biological activities of benzoyliminothiadiazoline derivatives which have potential affinities for angiotensin II receptor are described. The contributions of substituent (R(1)) on the benzene ring in benzoyl moiety and 5-position substituent (R(2)) on the 1,3,4-thiadiazoline ring were quantitatively investigated.

Abstract Convenient and efficientone-pot syntheses of 5-substituted-1,3,4-thiadiazol-2-ylcarbamoyl aliphatic amide acid derivatives were described and developed using sulfamic acid catalyst. Thiosemicarbazide and substituted triethylorthoester and cyclic/alicyclic anhydride were efficiently condensed using sulfamic acid to furnish 5-disubstituted-1,3,4-thiadiazol-2-ylcarbamoyl aliphatic acid and amide
