  Hydroxamic Acid Derivatives of Mycophenolic Acid Inhibit Histone Deacetylase at the Cellular Level

  摘要：

  麦克芬酸（MPA，1）是一种IMP脱氢酶（IMPDH）抑制剂和潜在的PPARγ激动剂，作为一种有效的免疫抑制剂用于临床移植，并且最近已在晚期多发性骨髓瘤患者中进入临床试验。另一方面，亚丁酸（SAHA）是一种非特异性组蛋白去乙酰化酶（HDAC）抑制剂，已被批准用于治疗皮肤T细胞淋巴瘤。MPA似乎具有一个帽结构、一个链接器和一个弱金属结合位点，作为HDAC的潜在抑制剂。因此，设计并合成了具有有效金属结合位点的麦克芬酸氢氧酸衍生物：麦克芬酸氢氧酸（MPHA，2）、7-O-乙酰麦克芬酸（7-O-Ac MPHA，3）和7-O-月桂酰麦克芬酸氢氧酸（7-O-L MPHA，4）。所有这些化合物均抑制组蛋白去乙酰化酶，其IC50值分别为1、0.9和0.5μM，细胞增殖抑制浓度为2、1.5和1μM。

  Mycophenolic acid (MPA), an inhibitor of IMP-dehydrogenase (IMPDH), is used worldwide in transplantation. Recently, numerous studies showed its importance in cancer treatment. Consequently, MPA entered clinical trials in advanced multiple myeloma patients. Suberoylanilide hydroxamic acid (SAHA), a potent differentiation agent acting through inhibition of histone deacetylases (HDACs), was recently approved for treatment of cutaneous T cell lymphoma. We report herein the synthesis of dual inhibitors of IMPDH and HDACs. We found that mycophenolic hydroxamic acid (9, MAHA) inhibits both IMPDH (K-i = 30 nM) and HDAC (IC50 = 5.0 mu M). A modification of SAHA with groups known to interact with IMPDH afforded a SAHA analogue 14, which inhibits IMPDH (K-i = 1.7 mu M) and HDAC (IC50 = 0.06 mu M). Both MAHA (IC50 = 4.8 mu M) and SAHA analogue 14 (IC50 = 7.7 mu M) were more potent than parent compounds as antiproliferation agents. They were also significantly more potent as differentiation inducers.
