腺苷衍生物
西奈芬净(9,sinefungin)是一种腺苷衍生物,属于泛甲基转移酶抑制剂,最初作为一种潜在的抗真菌药物从灰质链霉菌中分离出来。Hercik 等报道了西奈芬净与ZIKV甲基转移酶所形成配合物的晶体结构。SAM 为MTase 的天然底物,西奈芬净是其竞争性抑制剂。 西奈芬净与GTP 和GDP 类似物相结合,可能增强这些类似物对酶的亲和力,从而得到更好的选择性和对ZIKV 复制更强的抑制作用。然而,西奈芬净作为抗寄生虫剂在犬和山羊上进行实验时,被发现具有毒性,阻碍了其临床应用。
生物活性
Sinefungin是病毒粒子mRNA (鸟嘌呤-7-)-甲基转移酶、 mRNA (核苷-2-)-甲基转移酶和病毒增殖的有效抑制剂。Sinefungin 是一种 SET7/9 抑制剂,通过抑制H3K4甲基化来改善肾纤维化。
体外研究
Sinefungin (0.5 or 1.0 μg/mL, 60 minutes) ameliorates the TGF-β1-induced increase of α-SMA and inhibits the upregulation of histone H3K4 monomethylation in renal epithelial cells and renal fibroblast cells.
Western Blot Analysis
Cell Line: Renal epithelial cells.
Concentration: 0.5 or 1.0 μg/mL.
Incubation Time: Pretreatment 60 minutes before TGF-β1 (10 ng/mL).
Result: Significantly reduced TGF-β1-inducedα-SMA protein expression and inhibited H3K4me1 in a dose-dependent manner in both NRK-52E and NRK-49F cells.
