Background:

J22352 is a PROTAC (proteolysis-targeting chimeras)-like and highly selective HDAC6 inhibitor with an IC50 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[1]. HDAC6|4.7 nM (IC50)

J22352 (0.1-20 μM; 72 hours) decreases U87MG cell viability in a dose-dependent manner[1]. J22352 (10 μM; 24 hours) shows a dose-dependent decrease in HDAC6 protein abundance[1]. Cell Viability Assay[1] Cell Line: U87MG cells

J22352 (10mg/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[1]. Animal Model: Male nude mice (BALB/cAnN.Cg-Foxnlnu/CrlNarl, 4-6 weeks old)[1]
