GSK3368715 is an orally active, reversible, and S-adenosyl-L-methionine (SAM) uncompetitive type I protein arginine methyltransferases (PRMTs) inhibitor (IC50s: 3.1 nM (PRMT1), 48 nM (PRMT3), 1148 nM (PRMT4), 5.7 nM (PRMT6), 1.7 nM (PRMT8)). It has strong anti-cancer activity.
GSK3368715, a potent inhibitor of type I protein arginine methyltransferases (PRMT), could inhibit PRMT1, 3, 4, 6 and 8 with Kiapp vaules ranging from 1.5 to 81 nM.
Spermine (Neuridine) 是人体内源性多胺类物质,作为一个直接的自由基清除剂,具有抗病毒作用,能够保护 DNA 免受自由基的攻击,同时也是细胞增殖、分化、凋亡的关键调控因子。Spermine 能够抑制某些细菌,尤其是金黄色葡萄球菌菌株。Spermine 剂量依赖性地引起纹状体神经毒性。Spermine 可逆地抑制小鼠脾细胞原代培养中的 DNA 合成反应、混合淋巴细胞反应和溶细胞淋巴细胞反应的诱导。
Furamidine is also a selective and cell-permeable protein arginine methyltransferase 1 (PRMT1) inhibitor with an IC50 of 9.4 μM. Furamidine is selective for PRMT1 over PRMT5, PRMT6, and PRMT4 (CARM1) (IC50s of 166 μM, 283 μM, and >400 μM, respectively). Furamidine (DB75) is abisbenzamidine derivative and an antiparasite agent. Furamidine is a potent, reversible and competitive tyrosyl-DNA phosphodiesterase 1 (TDP-1) inhibitor. Inhibition of TDP-1 by Furamidine is effective both with single- and double-stranded DNA substrates but is slightly stronger with the duplex DNA.
PRMT5-IN-19 (Compound 41) is a potent orally active PRMT5 inhibitor, exhibiting selectivity towards the SAM-binding pocket of PRMT5 with IC50 values of 23.9 nM (radioactive biochemical assay) and 47 nM (AlphaLISA assay). It effectively blocks methyltransferase activity and demonstrates high specificity against other PRMTs and PKMTs. PRMT5-IN-19 exerts anti-proliferative effects through the induction of apoptosis and holds potential in cancer-related research [1].
