CAS No. : 2650074-56-7
MCE 国际站:Seconeolitsine
产品活性:Seconeolitsine,一种抗生素,是一种靶向拓扑异构酶 I (TopA)的抑制剂。Seconeolitsine 也是一种新的抗菌剂,可以抑制 S. pneumoniae 的生长。Seconeolitsine 具有抑制 TopA 的活性,其 b>IC50 值为 17 μM。Seconeolitsine 可用于对其他抗生素耐药的肺炎链球菌感染的研究。
研究领域:Anti-infection | Cell Cycle/DNA Damage
作用靶点:Antibiotic | Bacterial | Topoisomerase
In Vitro: Seconeolitsine (compounds 17) inhibits TopA relaxation activity in a concentration-dependent manner, with an IC50 value of 17 μM and the inhibition of TopA is enhanced by preincubation of the enzyme with the alkaloid.
Seconeolitsine shows great inhibition of S.pneumoniae growth with MIC50 values of 16 μM for R6, ATCC6303, CipS8, CipS9, CipR20, CipR16, CipR8, CipR45 and CipR5. And shows great inhibition of S. pneumoniae growth with MIC50 values of 8 μM for CipR42, CipR68 and CipR15.
Seconeolitsine has activation at low concentrations and partial inhibition at 50 μM, a concentration at which the pneumococcal TopA showed full inhibition, but not inhibits Human TOPO1.
Seconeolitsine (0.25×-1×MIC) affects cell growth and division in a concentration-dependent manner.
Seconeolitsine (30 and 100 μM), is not affected neutrophil apoptosis and human cell viability.
In Vivo: Seconeolitsine (compounds 17) increases supercoiling and TopA is target in vivo.
