产品描述

ICA-105665 (PF-04895162) is a potent and orally active neuronal Kv7.2/7.3 and Kv7.3/7.5 potassium channels opener. ICA-105665 inhibits liver mitochondrial function and bile salt export protein (BSEP) transport (IC50 of 311 μM). ICA-105665 can penetrate the blood-brain barrier and has antiseizure effects[1][2][3][4].

ICA-105665 (PF-04895162) does not display potent cytotoxic properties in THLE and HepG2 cell lines (IC50 ~192 μM and 130 μM after 72 hours, respectively) or in human hepatocytes (AC50 for cell loss at 48 hours was >125 μM based on results in three assessments in two different human hepatocyte lots (LBN and HU4165)[1].Mitochondrial respiratory reserve is compromised in human hepatocytes treated with ICA-105665 (PF-04895162) at concentrations >11 μM for 25 minutes[1].

For ICA-105665 (PF-04895162), in a 7-day rat toxicity study, dose-dependent alanine aminotransferase (ALT) elevations, potentially indicative of liver toxicity, were observed. However, no histological evidence of liver injury was identified, and ALT elevations were not confirmed in a repeat 7-day study. Further, 28 day and 6 month toxicity studies in rats were negative for transaminase elevations and liver toxicity, and toxicity studies up to 9 months duration in cynomolgus monkeys were also negative[2]. ICA-105665 (PF-04895162) has demonstrated broad spectrum antiseizure activity in multiple animal models including maximal electroshock, 6 Hz seizures, pentylenetetrazole, and electrical kindling at doses from<1 to 5 mg/kg[3].
