A series of N-[[(dialkylamino)alkoxyl]phenyl]benzamidines was synthesized and evaluated for hypoglycemic activity in the glucose-primed rat. Structure-activity relationship indicated that N'-phenyl-N-[4-[2(diisopropylamino)-ethoxy]phenyl]benzamidine dihydrobromide (7), N'-(4-chlorophenyl)-N-[4-[2-(diisopropylamino)ethoxy]phenyl]-benzamidine dihydrochloride (31), and N'-phenyl-N-[4-[(diisopropylamino)propoxy]phenyl]benzamidine dihydrobromide (11) are some of the more interesting compounds. A comparison of these hypoglycemic agents with classical standards (tolazamide, phenformin, and buformin) in several experimental models showed that the benzamidines seem to combine in one molecule some of the biological activities of the beta-cytotrophic sulfonylureas and some of the activities of the biguanides.

Quantitative Structure–Activity Analyses of Novel Hydroxyphenylurea Derivatives as Antioxidants
importance in governing the inhibitory potency. An increase in the electron donating property of substituents toward the phenolic hydroxyl group enhanced the antioxidative activity by the stabilization of an electron-deficient radical-type transition state. The steric shielding by ortho-substituents stabilized the phenoxyradicals formed following the transition state. Derivatives having the carboxyl group
