Abstract
組織蛋白去乙醯酶抑制劑(Histone deacetylase inhibitor, HDACi)目前廣泛的用於治療癌症,其中已有多種藥物上市,例如默克藥廠的小分子化合物ZolinzaR(vorinostat, SAHA, FDA approved for treatment of refractory cutaneous T-call lymphoma in 2006)和Gloucester藥廠的RomidepsinR(FK-228, FDA approved for treatment of refractory cutaneous T-call lymphoma in 2009),以上都證明此類藥物為治療癌症之有效策略。
本實驗室觀察相關HDACi後發現,N-hydroxyacrylamide和benzamide等官能基在抑制活性上扮演重要角色;含氮之[6,5] 雜環,例如indole,在許多抗癌小分子化合物中為重要骨架,因此本實驗室決定探討含氮之[6,5] 雜環在其N位以苯磺胺類或是苯烷基連結,導入N-hydroxyacrylamide和benzamide官能基,合成二系列化合物,進一步了解HDAC抑制活性與結構之間關係。
實驗室合成出的二系列化合物對口腔上皮細胞癌KB cell line做生物活性試驗,目前已知的資料中12d、17d、24c、28b有相似的活性,其中以24c IC50 = 604.6 nM最好。目前其他化合物活性實驗仍在進行中,此後將會作HDAC抑制活性試驗與結構修飾。
