Et-3,4-dephostatin, a protein-tyrosine phosphatase (PTPase) inhibitor, potentiates insulin-dependent signal transduction and shows an antidiabetic effect in mice. However, it contains a nitrosamine moiety that is often mutagenic and carcinogenic. Therefore, we previously designed and synthesized methoxime-3,4-dephostatin as a nitrosamine-free analogue

We have isolated signal transduction inhibitors of low molecular weight from microorganisms and plants. Since inducers of differentiation and apoptosis may be developed as new anticancer agents, we have studied induction of differentiation and apoptosis in neoplastic cells by our

Protein tyrosine phosphatase 1B (PTP1B) has been implicated as one of the key negative regulators of insulin and leptin signal transduction pathways. PTP1B deficient mice are more sensitive to insulin, and have improved glycemic control and resistance to diet-induced obesity

The cyclin-dependent kinase inhibitor p21(Cip1) is up-regulated in response to mitogenic stimulation in various cells. PPARgamma ligands troglitazone (TRO, 10 microm) and rosiglitazone (RSG, 10 microm) attenuated the induction of p21(Cip1) protein by platelet-derived growth factor (PDGF) and insulin without

Dephostatin, a novel tyrosine phosphatase inhibitor, was isolated from the culture broth of Streptomyces sp. MJ742-NF5. The structure was elucidated to be 2-(N-methyl-N-nitroso)hydroquinone by spectral and chemical analyses of dephostatin and its derivatives.
