Enoxacin

CAS No. : 74011-58-8

MCE 站：Enoxacin

产品活性：Enoxacin (AT 2266) 是一种氟喹诺酮，可以干扰 DNA 复制，抑制细菌 DNA 促旋酶 (IC₅₀=126 ?g/ml) 和拓扑异构酶 IV (IC₅₀=26.5 ?g/ml)。Enoxacin 是一种 miRNA 加工激活剂，可增强 siRNA 介导的 mRNA 降解并促进内源性 miRNA 的生物发生，也可增强 TAR RNA 结合蛋白 2 (TRBP) 介导的 microRNA 加工。Enoxacin 有效抑制革兰氏阳性和阴性细菌， 是一种特异性的癌症生长抑制剂。

研究领域：Anti-infection  |  Cell Cycle/DNA Damage  |  Epigenetics

作用靶点：Bacterial  |  DNA/RNA Synthesis  |  MicroRNA  |  Antibiotic

In Vitro: Enoxacin (AT 2266) increases siGFP-mediated gene knockdown mediated by siRNA against EGFP in HEK293 cells-based reporter system in a dose-dependent manner, with a median effective concentration (EC50) of ~30 ?M, whereas it has no effect on the cells expressing GFP only. Enoxacin (50 ?M) promotes the processing of miRNAs and the loading of siRNA duplexes onto RISCs in HEK293 cells.
Enoxacin has no effect on the processing of pre-let-7 or pre-miR-30a by Dicer alone. However, the addition of Enoxacin can enhance the processing of let-7 or pre-miR-30a by Dicer and TRBP together.
Enoxacin inhibits 90% Escherichia coli, Klebsiella sp., Aeromonas sp., Enterobacter spp., Serratia spp., Proteus mirabilis, and Morganella morganii at less than or equal to 0.8 micrograms/ml.

In Vivo: Enoxacin (AT 2266; 100 ?M; 2 ?l; injected into ear once a day for 3 consecutive days (days 12, 13 and 14)) enhances the the GFP mRNA knockdown efficiency by Lv-siGFP (from 80% to 60%; 40% GFP mRNA level remained), whereas alone has no effect on GFP expression in GFP transgenic line C57BL/6-Tg(ACTB-EGFP)1Osb/J (10 d old) with lentivirus expressing shGFP (Lv-siGFP; injected into ear for 10 days).
