Apexbio Technology LLC MI-77301 (SAR405838) 1303607-60-4 10mM (in 1mL DMSO)
MI-77301 (SAR405838 CAS 1303607-60-4) is a selective antagonist targeting the murine double minute 2 (MDM2) protein an E3 ubiquitin ligase responsible for negatively regulating tumor-suppressor p53 via ubiquitination and degradation By inhibiting the MDM2-p53 interaction (Ki 0 88 nM) MI-77301 stabilizes p53 elevates protein levels of p53 p21 and MDM2 and induces apoptosis Preclinical studies demonstrate selective growth inhibition in tumor cell lines harboring wild-type p53 (e g SJSA-1 RS4 11 LNCaP HCT-116) and potent tumor regressions in corresponding xenograft mouse models highlighting its utility for mechanistic studies and cancer therapeutic research
