3,4-Dihydroxy-N-methyl-N-nitrosoaniline

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

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).
