Application

Methyl-3,4-dephostatin has been used as:
  • an inhibitor for methyltransferases
  • a kinase-related inhibitor for human transglutaminase
  • a cysteine binding compound for screening its effect on C-terminal domain (CTD) of human immunodeficiency virus (HIV-1) capsid protein

Biochem/physiol Actions

Methyl-3,4-dephostatin is a tyrphostin-related compound isolated from Streptomyces MJ742-NF5 strain. It favors nerve growth factor-based neurite formation in pheochromocytoma PC12 cells. Being a stable analog of the nitrosoaniline dephostatin, it can mimic phosphotyrosine substrate for Tyrosyl-DNA phosphodiesterase I (TdpI).
Stable analog of dephostatin; selective protein tyrosine phosphatase 1B and SHPTP-1 inhibitor; does not inhibit CD45-associated phosphatases.

Human tissue transglutaminase (TGM2) is a calcium-dependent crosslinking enzyme involved in the posttranslational modification of intra- and extracellular proteins and implicated in several neurodegenerative diseases. To find specific inhibitors to TGM2, two structurally diverse chemical libraries (LOPAC and Prestwick) were

We have synthesized derivatives of dephostatin, a protein tyrosine phosphatase (PTPase) inhibitor, to study the structure-activity relationships of this inhibitor. Inactive analogs revealed some insight into structural requirements or PTPase inhibitory activity of dephostatin. Both a nitroso group and phenolic
