产品详情

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 IC 50 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.

体外研究(In Vitro)

Trovafloxacin (20 μM; 24 hours; HepG2 cells) and tumor necrosis factor (TNF; 4 ng/mL) incubation induces apoptosis and increases leakage of lactate dehydrogenase (LDH) in HepG2 cells.
Trovafloxacin (20 μM; 24 hours; HepG2 cells) and TNF (4 ng/mL) incubation increases expression of early NF-κB-related factors A20 and IκBα.
Trovafloxacin prolongs TNF-induced activation of MAPKs and IKKα/β activation in HepG2.
Trovafloxacin is a potent inhibitor of TO-PRO-3 uptake by apoptotic cells. Trovafloxacin also inhibits ATP release from apoptotic cells. Trovafloxacin does not inhibit caspase 3/7 activation, or caspase-mediated PANX1 cleavage during apoptosis.
Trovafloxacin is equally active against both penicillin-susceptible and -resistant pneumococci, with MICs of 0.06-0.25 mg/mL reported for more than 700 isolates. The MICs of Trovafloxacin at which 90% of isolates are

体内研究(In Vivo)

Trovafloxacin (150 mg/kg; oral administration; male C57BL/6 J mice) treatment disrupts TNF-induced p65 nuclear translocation. Trovafloxacin treatment increases expression of early NF-κB-related factors A20 and IκBα.
Trovafloxacin, when administered in combination with lipopolysaccharide (LPS) or TNF to mice induces severe liver toxicity associated with vast apoptotic areas in the liver, increased serum levels of alanine amino transferases (ALT) and pro-inflammatory cytokines. has not independently confirmed the accuracy of these methods. They are for reference only.

产品使用指南

Data Sheet

1：一般建议：溶解度为Medlife测试数据，可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解，请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异，仅做参考，具体以实验方案为准。

2：储存条件：粉末-20°C一般情况可以保存3年，溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异，请细致阅读产品信息，并辅助参考相关文献描述。
