Research use only, not for human use.

Quisinostat (JNJ-26481585) 2HCl is a novel second-generation HDAC inhibitor with highest potency for HDAC1 with IC50 of 0.11 nM in a cell-free assay.

Quisinostat (JNJ-26481585) 2HCl is a novel second-generation HDAC inhibitor with highest potency for HDAC1 with IC50 of 0.11 nM in a cell-free assay, modest potent to HDACs 2, 4, 10, and 11; greater than 30-fold selectivity against HDACs 3, 5, 8, and 9 and lowest potency to HDACs 6 and 7. Phase 2.(In Vitro):JNJ-26481585 inhibits HDAC isozymes in vitro.JNJ-26481585 (30-1000 nM; 24 hours) is a potent pan-HDAC inhibitor in tumor cells.JNJ-26481585 has broad spectrum antiproliferative activity against solid and hematologic cancer cell lines and induces apoptosis.(In Vivo):JNJ-26481585 (40 mg/kg; p.o.; once daily, for 3 days) as a potent HDAC1 inhibitor p21waf1,cip1 ZsGreen tumors in vivo.JNJ-26481585 induces continuous H3 acetylation in tumor tissue in vivo.JNJ-26481585 (10 mg/kg; once daily; i.p.; for 14 days) strongly inhibits the growth of large pre-established HCT116 colon xenografts.
