An HDAC inhibitor
Vorinostat (suberoylanilide hydroxamic acid, SAHA) is a histone deacetylase inhibitor (HDACi), that plays key roles in epigenetic or non-epigenetic regulation, inducing growth arrest, differentiation and apoptosis of tumor cells.[1] Vorinostat is a small molecular with the formular of C14H20N2O3 and molecular weight of 264.3. The major mechanism of HDACi-induced apoptosis is the activation of the intrinsic apoptotic pathway. HDACi can activate the intrinsic apoptotic pathway by releasing of cytochrome c from mitochondria and regulating of Bcl-2 family expression.[2]
Vorinostat（又称亚硝基苯酰氢氧酰胺）是一种组蛋白去乙酰化酶抑制剂（HDACi），在表观遗传或非表观遗传调控中发挥重要作用，可诱导肿瘤细胞生长停滞、分化和凋亡[1]。 Vorinostat是一种小分子，化学式为C14H20N2O3，分子量为264.3。 HDACi诱导凋亡的主要机制是激活内在凋亡通路。 HDACi可以通过释放线粒体中的细胞色素c和调节Bcl-2家族表达来激活内在凋亡通路[2]。

Animal models |
C57BL/6 mice bearing Eμ-myc lymphomas |
|
Dosage form |
C57BL/6 mice bearing Eμ-myc lymphomas were injected with vorinostat (200 mg/kg i.p.) and lymphoma cells were harvested after the indicated time points. The percentage of tumor cells in the lymph node of C57BL/6mice bearing Eμ-myc lymphomas treated with vorinostat was determined by FACS analysis. |
|
Applications |
Vorinostat induced a marked accumulation of Eμ-myc lymphomas displaying DNA fragmentation in vivo. |
|
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
