Abstract
indirubin藥理作用具有抑制cyclin-dependent kinase(CDKs)、glycogen synthesis kinase(GSK-3)也是aryl hydrocarbon receptor (AhR)致效劑。因indirubin抑制CDK便會造成細胞週期停止在G1 and G2/M phase,進而抑制細胞增生或是細胞毒殺。Indirubin曾在慢性骨髓白血病(CML)臨床試驗發現副作用很少,不會影響造血功能、肝及腎功能。為改善indirubin溶解度不佳,並增加活性,經化學構造修飾並探討indirubin之化學構造與藥效關係。本論文擬合成indirubin衍生物並探討結構與藥效的關係,提供藥物設計者的重要參考。 合成indirubins最簡便的方法就是在無氧的情況下結合indoxyl acetate和isatins(63~73)便得到化合物3、30~39 (產率:70~90%)。利用3,4位不同取代的aniline加入chloral hydrate和NH2OH HCl反應得到isonitrosoacetanilides (57~62),以濃硫酸或是BF3當催化劑加熱會產生isatins (63~68)。Indirubins(3、30~39)用pyridine溶解再加入NH2OH HCl即能得到indirubins -3’-oximes(20、40~49),產率為70~80%。 藉由MTT assay可發現對於MCF-7抗乳癌活性最好的是化合物49和48,IC50為9.67、16.9μM;對於U937抗白血病活性最好的是化合物44和42 ,IC50為3.95、4.67μM,化合物40、41、43、48、49仍比化合物20有效,化合物45、46、47對兩種細胞均無抑制作用。
