J22352 is a PROTAC (proteolysis-targeting chimeras)-like and highly selective HDAC6 inhibitor with an IC 50 value of 4.7 nM. J22352 promotes HDAC6 degradation and induces anticancer effects by inhibiting autophagy and eliciting the antitumor immune response in glioblastoma cancers, and leading to the restoration of host antitumor activity by reducing the immunosuppressive activity of PD-L1 In Vitro J22352 (0.1-20 μM; 72 hours) decreases U87MG cell viability in a dose-dependent manner. J22352 (10 μM; 24 hours) shows a dose-dependent decrease in HDAC6 protein abundance. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Cell Viability AssayCell Line: U87MG cells Concentration: 0.1 μM; 0.5 μM; 1μM; 2.5 μM; 5 μM; 10 μM; 20 μM Incubation Time: 72 hours Result: A dose-dependent decrease on U87MG cell proliferation. Western Blot AnalysisCell Line: U87MG cells Concentration: 10 μM Incubation Time: 24 hours Result: A dose-dependent decrease in aberrant overexpression of HDAC6 in glioblastoma. In Vivo J22352 (10 mg/kg; given i.p. per day for 14 days in male nude mice) results in a >80% tumor growth inhibition (TGI) rate. J22352 is well tolerated in mice . MCE has not independently confirmed the accuracy of these methods. They are for reference only. Animal Model: Male nude mice (BALB/cAnN.Cg-Foxnlnu/CrlNarl, 4-6 weeks old) Dosage: 10 mg/kg Administration: Given i.p.; per day for 14 days Result: Marked anti-tumor effects and well tolerated in mice.
