4-Chloro-3-nitro-, 4-hydrazino-3-nitro-, o- and m-nitro-, p-bromo-, 2,4-, 2,5-, and 3,4-dichloro-, also 2,3,4- 2,4,5-, and 2,4,6-trichloro-benzenesulphonhydrazides have been prepared and converted into a number of derivatives (e.g., hydrazones, azides) required as potential pest-control agents. The relative stability of the various sulphonyl hydrazides is briefly discussed.

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).
