Antihyperglycemic activity of novel substituted 3H-1,2,3,5-oxathiadiazole 2-oxides
摘要:
A series of substituted 3H-1,2,3,5-oxathiadiazole-2-oxides (6) was prepared and tested for antihyperglycemic activity in the db/db mouse, a model for type 2 (non-insulin dependent) diabetes mellitus. The oxathiadiazoles 6 were synthesized by a two-step sequence: treatment of a substituted acetonitrile (4) with hydroxylamine to give the corresponding amidoxime (5) and cyclization with thionyl chloride to yield 6. In terms of potency, the 2-naphthalenylmethyl group (as in compound 3) was found to be the optimal substituent in this series. Compound 3 was approximately 5 times more potent than ciglitazone (1).

Replacement of the isothiourea moiety of known histamine H-3 antagonists by certain 5-membered heteroaromatic systems can give compounds with an improved activity profile. One of these, 3-[(4-chlorophenyl)methyl]-5-[2-(1H-imidazol-4-yl)ethyl] 1,2,4-oxadiazole (GR175737) is a potent, selective, orally active and centally penetrating H-3 antagonist.

Abstract A protocol has been devised for the synthesis of 3-substituted 5-amino-1,2,4-thiadiazoles utilizing isothiocyanates, amidoximes and water as an eco-friendly solvent. The strategy involves consecutive C−N and S−N bonds formation in a one-pot reaction under catalyst-free conditions. Operational simplicity, low cost, broad substrate scope and readily available starting materials are the main
