    • The present invention provides methods of selectively inducing terminal differentiation, cell growth arrest and/or apoptosis of neoplastic cells, and/or inhibiting histone deacetylase (HDAC) by administration of pharmaceutical compositions comprising potent HDAC inhibitors. The oral bioavailability of the active compounds in the pharmaceutical compositions of the present invention is surprisingly high. Moreover, the pharmaceutical compositions unexpectedly give rise to high, therapeutically effective blood levels of the active compounds over an extended period of time. The present invention further provides a safe, daily dosing regimen of these pharmaceutical compositions, which is easy to follow, and which results in a therapeutically effective amount of the HDAC inhibitors in vivo. The present invention also provides a novel Form I polymorph of SAHA, characterized by a unique X-ray diffraction pattern and Differential Scanning Calorimetry profile, as well a unique crystalline structure.
    • 本发明提供了通过施用包含有效的HDAC抑制剂的药物组合物选择性诱导肿瘤细胞的终末分化,细胞生长停滞和/或细胞凋亡和/或抑制组蛋白脱乙酰酶(HDAC)的方法。 本发明的药物组合物中活性化合物的口服生物利用度令人惊奇的高。 此外,药物组合物在长时间内意外地引起活性化合物的高,治疗有效的血液水平。 本发明进一步提供这些药物组合物的安全的每日给药方案,其易于遵循,并且其在体内导致治疗有效量的HDAC抑制剂。 本发明还提供了SAHA的新型I型多晶型物,其特征在于独特的X射线衍射图和差示扫描量热法谱,以及独特的晶体结构。
