生物活性

AMI-1 是一种有效的，细胞渗透性的，可逆的蛋白精氨酸 N-甲基转移酶 (PRMTs) 抑制剂，对人 PRMT1 和酵母 Hmt1p 作用的 IC50 值分别为 8.8 μM 和 3.0 μM。AMI-1 通过阻断肽-底物结合对 PRMTs 发挥抑制作用。

靶点

IC50: 8.8 μM (PRMT1), 3.0 μM (yeast-Hmt1p)

体外研究

AMI-1 can inhibit the in vitro methylation reactions performed by all five recombinantly active PRMTs (PRMT1, -3, -4, and -6 and Hmt1p). AMI-1 not only inhibits type I PRMTs (PRMT1, 3, 4 and 6) but also type II PRMT5. AMI-1 specifically inhibits arginine, but not lysine, methyltransferase activity in vitro and does not compete for the AdoMet binding site. AMI-1 inhibits methylation of GFP-Npl3 and cellular proteins. AMI-1 (0.6-2.4 mM; 48-96 hours) inhibits the cell viability of sarcoma in S180 and U2OS cells in a time-dependent and dose-dependent manner in vitro. AMI-1 (1.2-2.4 mM; 48-72 hours) reduces S180 cell viability through the induction of cell apoptosis. Cell Viability Assay Cell Line: S180 cells, U2OS cells Concentration: 0.6 mM, 1.2 mM, 2.4 mM Incubation Time: 48 hours, 72 hours, 96 hours Result: Inhibited the cell viability. Apoptosis Analysis Cell Line: S180 cells Concentration: 1.2 mM, 2.4 mM Incubation Time: 48 hours, 72 hours Result: Increased the percentages of cells undergoing apoptosis.

AMI-1 (0.5 mg; intratumorally; daily; for 7 days) inhibits S180 viability in vivo. AMI-1 (0.5 mg; intratumorally; daily; for 7 days) downregulates PRMT5 but does not regulate the expression of PRMT7 in a tumor xenograft model. AMI-1 (0.5 mg; intratumorally; daily; for 7 days) decreases the levels of H4R3me2s and H3R8me2s in a tumor xenograft model. Animal Model: 6-7 weeks old male Kunming mice (18-22 g), with S180 cells xenograft Dosage: 0.5 mg Administration: Intratumorally, daily, for 7 days Result: Decreased tumor weight.
