Previously compound I showed great anti‐glioblastoma activity without toxicity in a mouse xenograft study. In this study, a sensitive and rapid high‐performance liquid chromatography–tandem mass spectrometry (HPLC–MS/MS) method was developed and validated to investigate the pharmacokinetics and brain distribution of compound I in mice. The protein precipitation method was applied to extract the compound from mouse plasma and brain homogenates, and it was then separated using a Kinetex C 18 column with a mobile phase consisting of acetonitrile–0.1% formic acid water (50:50, v/v). The analytes were detected with multiple reaction monitoring for the quantitative response of the compounds. The inter‐ and intra‐day precisions were <8.29 and 3.85%, respectively, and the accuracy range was within ±7.33%. The method was successfully applied to evaluate the pharmacokinetics of compound I in mouse plasma and brain tissue. The peak concentration in plasma was achieved within 1 h. The apparent elimination half‐life was 4.06 h. The peak concentration of compound I in brain tissue was 0.88 μg/g. The results indicated that compound I was rapidly distributed and could cross the blood–brain barrier. The pharmacokinetic profile summarized provides valuable information for the further investigation of compound I as a potential anti‐glioblastoma agent.
