A facile and atom-economical boric acid catalyzed direct amidation without any coupling
agents for the preparation of Suberoylanilide Hydroxamic Acid (SAHA) and SAHA-based inhibitors
targeting anti-proliferation of cancer cells is described. It is applicable to the preparation of SAHAbased
inhibitors having an unprotected hydroxyl group in the phenyl ring without the need of the protection.
The in-vitro assays data indicate that the nature and the position of the substituents (activating
and/or deactivating) in the capping group (phenyl ring) of SAHA-based inhibitors synthesized in this
study have a vital impact on the potency of anti-proliferative activity against cancer cells. With low toxicity toward the
normal cells, a number of synthesized SAHA-based inhibitors with two substituents in the phenyl ring possess higher antiproliferative
activity than SAHA and Cisplatin toward six studied cancer cell lines: A375 human skin cancer cells, A549
human lung cancer cells, MGC80-3 human gastric cancer cells, H460 human lung cancer cells, H1299 human lung cancer
cells, and HepG2 human liver cancer cells. Cisplatin is a common chemotherapeutic drug with high cytotoxicity for a variety
of cancer treatments. The inhibitors provided in this study might signify future therapeutic drugs for cancer
treatment.
本文描述了一种简便且原子经济性的硼酸催化直接酰胺化反应,无需任何偶联剂,用于制备辛二酰胺酸羟肟酸(SAHA)及其靶向抗肿瘤细胞增殖的抑制剂。该方法适用于制备具有苯环上未保护羟基的SAHA基抑制剂,无需保护步骤。体外试验数据显示,在本研究中合成的SAHA基抑制剂的封端基团(苯环)上取代基(活化或去活化)的性质和位置对抑制癌细胞增殖活性的强弱有重要影响。这些合成出的SAHA基抑制剂对正常细胞的毒性较低,其中一些具有苯环上两个取代基的抑制剂在抑制六种研究癌症细胞系(A375人皮肤癌细胞、A549人肺癌细胞、MGC80-3人胃癌细胞、H460人肺癌细胞、H1299人肺癌细胞和HepG2人肝癌细胞)的增殖活性上,优于SAHA和顺铂。顺铂是一种常见的化疗药物,对多种癌症治疗具有高细胞毒性。本研究提供的抑制剂可能预示着未来用于癌症治疗的新型药物。
