Novobiocin Sodium (Synonyms:Albamycin; Cathomycin)
目录号 : KM11815 CAS No. : 1476-53-5 纯度 : 95%

Novobiocin Sodium (Albamycin; Cathomycin) 是一种口服抗生素 (antibiotic) 化合物,源于链霉菌,也是一个强效的 DNA gyrase 抑制剂通过结合 ATP 结合位点在 ATP 酶亚基。Novobiocin Sodium 对革兰氏阳性菌有较强的抗菌活性,但由于外膜中含有脂多糖,对革兰氏阴性菌的抗菌活性有限。Novobiocin Sodium 与 Hsp90 的 c 端结合,轻微诱导 Hsp90 依赖的 client 蛋白的降解 (IC50=700 μM)。

生物活性

Novobiocin Sodium (Albamycin; Cathomycin) is an orally active antibiotic compound derived from Streptomyces niveus and a potent DNA gyrase inhibitor by binding the ATP-binding site in the ATPase subunit. Novobiocin Sodium manifests strong anti-bacterial activities effectively against gram-positive pathogens and shows limited activity against gram-negative organisms due to LPS-containing outer membrane.Novobiocin Sodium binds to the C-terminus of Hsp90 and slightly induces degradation of Hsp90-dependent client proteins (IC50=700 µM).

体外研究

Novobiocin Sodium (0.3 mM; 48 hours) induces a caspase-3/7 enzyme–dependent apoptosis assays with an induction of approximately three- to fivefold of apoptotic cells in K562, HL60, Mutz-2.
Novobiocin (0-500 μM; 15-hours) is against wild type, lptB1lptB1(R144H), and efflux pump-deficient ∆tolC strains with IC50 values of 62.5-125 μM; 0.5 μM; 62.5-125 μM; and 2 μM, respectively.
