目录号: HY-A0170 纯度: 99.08%
COA 产品使用指南 技术支持

Trovafloxacin 是一种广谱喹诺酮类抗生素,对革兰氏阳性,革兰氏阴性和厌氧菌具有有效的活性。Trovafloxacin 可阻断 DNA 促旋酶 (DNA gyrase) 和拓扑异构酶 IV (topoisomerase IV) 的活性。Trovafloxacin 也是一种有效的,选择性的,口服活性的 Pannexin 1 通道 (PANX1) 抑制剂,对 PANX1 内向电流的 IC50 为 4 μM。Trovafloxacin 不抑制 connexin 43 gap junction 或 PANX2。Trovafloxacin 通过抑制 PANX1 导致凋亡细胞碎片失调。

生物活性

Trovafloxacin is a broad-spectrum quinolone antibiotic with potent activity against Gram-positive, Gram-negative and anaerobic organisms. Trovafloxacin blocks the DNA gyrase and topoisomerase IV activity. Trovafloxacin is also a potent, selective and orally active pannexin 1 channel (PANX1) inhibitor with an IC50 of 4 μM for PANX1 inward current. Trovafloxacin does not inhibit connexin 43 gap junction or PANX2. Trovafloxacin leads to dysregulated fragmentation of apoptotic cells by inhibiting PANX1[1][2][3].

(In Vitro)

Trovafloxacin (20 μM;24 小时;HepG2 细胞) 和肿瘤坏死因子 (TNF;4 ng/mL) 孵育可诱导细胞凋亡并增加 HepG2 细胞中乳酸脱氢酶 (LDH) 的泄漏[1]
Trovafloxacin (20 μM;24 小时;HepG2 细胞)和 TNF (4 ng/mL) 孵育可增加早期 NF-κB 相关因子 A20 和 IκBα 的表达[1]
Trovafloxacin 延长 HepG2 中 TNF 诱导的 MAPK 活化和 IKKα/β 活化[1]
Trovafloxacin 是凋亡细胞摄取 TO-PRO-3 的强效抑制剂。Trovafloxacin 还能抑制凋亡细胞的 ATP 释放。Trovafloxacin 不抑制凋亡过程中胱天蛋白酶 3/7 的活化,也不抑制胱天蛋白酶介导的PANX1的裂解[2]
Trovafloxacin 对青霉素敏感和耐药肺炎球菌均具有同等的活性,据报道,对超过 700 种分离株的 MIC 为 0.06-0.25 mg/mL。Trovafloxacin 对 55 种肺炎球菌分离株抑制 90% 分离株的 MIC 为 0.125 μg/mL[3]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
