The quinoline-3-carboxamide, Tasquinimod (TasQ), is orally active as a maintenance therapy with an on-target mechanism-of-action via allosteric binding to HDAC4. This prevents formation of the HDAC4/NCoR1/HDAC3 complex, disrupting HIF-1α transcriptional activation and repressing MEF-2 target genes needed for adaptive survival signaling in the compromised tumor micro environment. In phase 3 clinical testing against metastatic castration-resistant prostate cancer(mCRPC), TasQ (1 mg/day) increased time-to-progression, but not overall survival.

HDAC4、HIF-1α 和 MEF-2 信号传导的第三代喹啉-3-羧酰胺转录破坏基因,用于转移性去势抵抗性前列腺癌



喹啉-3-甲酰胺 Tasquinimod (TasQ) 作为一种维持疗法具有口服活性,通过与 HDAC4 变构结合具有靶向作用机制。这可以防止 HDAC4/NCoR1/HDAC3 复合体的形成,破坏 HIF-1α 转录激活,并抑制受损肿瘤微环境中适应性存活信号转导所需的 MEF-2 靶基因。在针对转移性去势抵抗性前列腺癌 (mCRPC) 的 3 期临床测试中,TasQ (1 mg/天) 增加了进展时间,但没有增加总生存期。
