Identification, biological activity, and mechanism of the anti-ischemic quinolone analog

Abstract The quinolone analog SQ-4004 has been identified as a potentially excellent anti-ischemic agent, which exhibited highly potent efficacy in reducing infarct volume size in vivo rat MCAO model (32.1% at 0.01 mg/kg) and potent cardioprotective effect at myocardial infarction in vivo model (26.6% at 0.01 mg/kg) while it exhibited highly reduced anti-bacterial activity. The mechanistic study revealed that the anti-ischemic activity might exert via an anti-apoptotic pathway, which implies its therapeutic uses against the ischemic cell injuries including ischemic stroke and ischemic heart disease.
