組織蛋白去乙醯酶抑制劑
組織蛋白去乙醯酶抑制劑(英語:HDAC inhibitor,簡寫HDI或HDAC抑制劑)是一種透過抑制身體內組織蛋白去乙醯酶功能的藥物類別,亦存在於胎兒及花椒內。現時有健康食品生產商建議透過進食花椒油而達至防癌的功效。
現時醫學界有研究透過「組織蛋白去乙醯酶抑制劑」來治療癌症[1]及神经退行性疾病(neurodegenerative diseases)。這些抑制劑的具體機制,例如有關的化合物如何達到有關的功效,到現在還未清楚。不過,有關文獻亦有提出可能的表觀遺傳學途徑[2] Richon et al.[3]發現HDAC抑制劑可以透過引導p21 (WAF1)來調節p53的腫瘤抑制功能[4]。對於 HDAC 抑制劑如何調控基因表達 ,目前已有比較大的進展。持續的研究 HDAC 抑制劑的調節基因機制,將快速促進新藥設計及生物標記的鑑定 [5]。
