A novel matrix metalloproteinase-2 inhibitor triazolylmethyl aziridine reduces melanoma cell invasion, angiogenesis and targets ERK1/2 phosphorylation.

A novel matrix metalloproteinase-2 (MMP-2) inhibitor JaZ-30, which belongs to the class of C(2)-monosubstituted aziridine - aryl-1,2,3-triazole conjugates, was developed. MTT and crystal violet assays were used to determine cytotoxicity- IC(50) values of compound JaZ-30 on melanoma cell line B16 4A5. Our study proves the anti-cancer properties of JaZ-30 with a wide spectrum of activities. JaZ-30 was revealed as selective inhibitor of matrix metalloproteinase-2. JaZ-30-mediated decrease of Vascular Endothelial Growth Factor (VEGF) secretion results in inhibition of angiogenesis, performed with the human umbilical vein endothelial cell line (HUVEC-2) on Matrigel. A novel inhibitor decreases invasive properties of melanoma cells measured in Matrigel chambers assay. JaZ-30 downregulates phosphorylation of the extracellular signal-regulated kinases 1 and 2 (ERK1/2) in melanoma cells stimulated by phorbol-12-myristate-13-acetate (PMA). Our findings propose a novel MMP-2 inhibitor JaZ-30 as an attractive potential agent for melanoma treatment.
