Synthesis and characterization of 2-(4-((1-alkyl or aryl-1H-1,2,3-triazol-4-yl)methoxy)phenyl)naphtho[1,2-d]oxazoles for protein tyrosine phosphatase 1B inhibitory activity
摘要:
2-(4-((1-Alkyl/aryl-1H-1,2,3-triazol-4-yl)methoxy)phenyl)naphtho[1,2-d] were prepared and evaluated as protein tyrosine phosphatase 1B (PTP1B) inhibitors. In this study, two new compounds with potent PTP1B inhibitory activity were identified.

Metal, oxidant and other additive-free novel methods for direct C–H aryloxylation of aliphatic amines are developed. In the presence of excess amine, the course of the reaction was diverted, producing various arylmethylamines via hydride-free formal reductive amination. Involvement of a quinonemethideintermediate was revealed from mechanistic studies.

A series of 2-aryl-naphtho[1,2-d]oxazole derivatives have been synthesized and evaluated for PTP-1B inhibitory activity. The compounds have been screened in vivo for antidiabetic activity under sucrose loaded model (SLM), sucrose-challenged streptozotocin-induced diabetic rat model (STZ-S) and db/db mice model. Compounds 8 and 12 have shown promising PTP-1B inhibitory activity, significant antidiabetic activity, moderate lipid and triglyceride lowering activity. (C) 2008 Elsevier Masson SAS.
