HPi1

CAS No. : 13080-21-2

MCE 站：HPi1

产品活性：HPi1 是一种针对幽门螺杆菌 (Helicobacter pylori) 的有效，选择性和具有口服活性的抗菌剂，IC₅₀ 为 0.24 μM，MIC 为 0.08-0.16 μg/mL。HPi1 对其他细菌无活性，包括肠道菌干酪乳杆菌，罗伊氏乳杆菌和长双歧杆菌。

研究领域：Anti-infection

作用靶点：Bacterial

In Vitro: The MIC against H. pylori isolates ranged from 0.002-0.032 μg/mL (0.01-0.17 μM) in the agar dilution assay. HPi1 is effective against the clarithromycin-resistant strains ARHp172 (MIC of 0.004–0.016 μg/mL) and ARHp246 (MIC of 0.008–0.032 μg/mL).
HPi1 has some activity against the Bacteroides species, but at concentrations at least 18-fold higher than the H. pylori MIC. More potent activity is detected for Campylobacter jejuni with an MIC of 0.3 μg/mL.
HPi1 has good physicochemical and pharmacological properties, including determining the aqueous solubility (19 μg/mL), human plasma protein binding (93% bound), stability with human liver microsomes (T_1/2 of 1.3 hours) and the ability to passively permeate membranes.

In Vivo: HPi1 (6.25-50 mg/kg; Oral gavage; once a day; for 3 days; female C57BL/6 mice) treatment decreases colony counts below the limit of detection at doses of 25 or 50 mg/kg/day.
