Manumycin A 是一种抗生素。Manumycin A 作为一种选择性、竞争性的 farnesyltransferase (FTase) 抑制剂，与 farnesylpyrophosphate (Ki =1.2 μM) 有关，并且作为 Ras 蛋白质的非竞争性抑制剂。Manumycin A 诱导细胞凋亡并发挥抗肿瘤活性。Manumycin A 通过靶向抑制 Ras/Raf/ERK1/2 信号转导，抑制外泌体生物发生 (exosome biogenesis) 及分泌。Manumycin A 也是 nSMase 抑制剂 (EC50=0.25 μM)。
| 生物活性 |
Manumycin A is an antibiotic. Manumycin A acts as a selective, competitive inhibitor of protein farnesyltransferase (FTase) with respect to farnesylpyrophosphate (Ki =1.2 μM), and as a noncompetitive inhibitor with respect to the Ras protein. Manumycin A induces apoptosis and exerts antitumor activity . Manumycin A suppresses exosome biogenesis and secretion via targeted inhibition of Ras/Raf/ERK1/2 signaling. Manumycin A is a nSMase inhibitor (EC50=0.25 μM). |
