產(chǎn)品簡(jiǎn)介：
喜樹(shù)堿是拓?fù)洚悩?gòu)酶I的選擇性抑制劑，IC50值為679 nM [1]。
喜樹(shù)堿可以誘導(dǎo)SMMC-7721、MCF-7和HCT-116腫瘤細(xì)胞的死亡。據(jù)報(bào)道，喜樹(shù)堿通過(guò)AMPK-TSC2-mTOR途徑誘導(dǎo)自噬，同時(shí)通過(guò)ATM-Chk2-p53-p21途徑誘導(dǎo)早衰[2]。 研究表明喜樹(shù)堿在非小細(xì)胞肺癌異種移植物中具有抗腫瘤活性。已經(jīng)發(fā)現(xiàn)喜樹(shù)堿誘導(dǎo)的DNA損傷導(dǎo)致H2AX (γH2AX)的磷酸化。以前的研究也證明了在用喜樹(shù)堿治療的癌細(xì)胞中減少Top1的表達(dá)[3]。
