The present invention is related to the use of oxindole hydrazide derivatives of formula (I) for the treatment and/or prevention of metabolic disorders mediated by insulin resistance or hyperglycemia, comprising diabetes type I and/or II, inadequate glucose tolerance, insulin resistance, hyperlipidemia, hypertriglyceridemia, hypercholesterolemia, obesity, polycystic ovary syndrome (PCOS). In particular, the present invention is related to the use of oxindole hydrazide derivatives of formula (I) to modulate, notably to inhibit the activity of PTPs, in particular of PTP1B, TC-PTP, SHP and GLEPP-1. The present invention is furthermore related to novel oxindole hydrazide derivatives and method of preparation thereof.(I).

Indium(III) Chloride Catalyzed Synthesis of 5-Substituted 1H-Tetrazoles from Oximes and Sodium Azide
A simple and efficient protocol has been developed for the synthesis of 5-substituted 1H-tetrazole derivatives in good to excellent yields from various oximes and sodium azide by using indium(III) chloride as a Lewis acid catalyst. The present method has significant advantages, such as an inexpensive catalyst, low catalyst loading, mild reaction conditions, and simple experimental procedures.
