I3MT-3 是一种有效的、具有细胞膜渗透性的、选择性的 3-巯基丙酮酸硫转移酶 (3MST)的抑制剂，IC50值为2.7 μM，对其他硫化氢/磺胺制硫酶没有活性。它靶向位于 3MST 活性位点的过硫半胱氨酸残基。

I3MT-3 (HMPSNE) is a potent, selective and cell membrane permeability inhibitor of 3-mercaptopyruvate sulfur transferase (3MST), which targets the persulfated cysteine residues located at the active site of 3MST.

I3MT-3 shows a dose-dependent inhibition of 3-MST activity from CT26 homogenates, which contain the murine form of the enzyme. The IC50 of HMPSNE for murine 3-MST is calculated as 2.3 μM with a cozncentration-dependent decrease of AzMC fluorescence[1].I3MT-3 (0-300 μM; 48 hours) inhibits CT26 cells proliferate with increasing concentrations of I3MT-3. Confluence of cells treated with HMPSNE is recorded each hour for 48 h by the IncuCyte method[2].
