Abstract:
N-[imino(ethyl ethylidine hydrazine)methyl]-N-aryl-2- amino-carbothioamidine hydrochlorides with ethylmethylketothiosemicarbazone in acetone medium at 0-5 degrees C. The carbothioamides were oxidized by H2O2 to 1,2,4-thiodiazolidine derivatives. The 4-Cl derivative in both the series was the most active hypoglycaemic agent. The compounds lowered mean blood sugar levels (MBSL) by 38.81% (compound 2, Table II) and 15.19% (compound 2, Table III) respectively after 24 hours of drug treatment. The compounds also showed antidiabetic activity in alloxan diabetic rats.
