描述 The inhibition of HDACs increases the acetylation of histone proteins, which affects the tertiary chromatin structure and leads to altered expression of genes involved in cell proliferation, apoptosis and differentiation. Thus, it makes a key role for inhibition of HDACs in anti-proliferation of tumor cells. Quisinostat is an oral pan-HDAC inhibitor with highest potency for HDAC1 (IC50=0.11±0.03nM, measured by recombinant HDAC enzyme activity), modest potent to HDAC 2, 4, 10 and 11nM and a lower potency on the rest HDACs. Increased level of acetylated histone H3 (H3 Ac), H4 (H4 Ac), histone H4-acetyl K16 (H4-K16 Ac) and histone H4-trimethyl K20 (H4-K20Me3) (acetylation regulated by HDAC1-3), p21 and E-cadherin (expression regulated by HDAC1), as well as increased tubulin acetylation, induction of Hsp70, and loss of Hsp90 client c-Raf can be observed in a dose-dependent manner (30-1000nM) after 24-hour treatment with Quisinostat in human A2780 ovarian carcinoma cells, which shows activity against pan-HDAC inhibition. Also, Quisinostat can inhibit cell growth in all lung, breast, colon, prostate, brain, and ovarian tumor cell lines tested with IC50 values ranging from 3.1 to 246nM, which shows its antiproliferative effect in a broad panel of human tumor cell lines from both solid and hematologic origin. Compared with the first generation of HDAC inhibitors (SAHA or TSA), Quisinostat shows prolonged pharmacodynamic response in vivo. Quisinostat can induce continuous H3 acetylation in tumor tissue from A2780 ovarian tumor-bearing nude mice when treated with Quisinostat at 10mg/kg as well as increased level of HDAC1-regulated p21[1]. Up to now, a phase I study of Quisinostat in patients with advanced solid tumors has been done[2].
作用机制 Quisinostat is a pyrimidyl-hydroxamic acid analogue, which can chelate the Zn2+ ion of HDAC. [1]
