  衣原霉素-异羟肟酸类似物作为组蛋白脱乙酰基酶抑制剂。

  摘要：

  根据衣原霉素和曲古抑菌素A的结构和HDAC抑制活性，设计并合成了衣原霉素-异羟肟酸类似物作为组蛋白脱乙酰基酶（HDAC）抑制剂。衣原霉素是环状四肽，在侧链中含有环氧酮部分，使其成为不可逆抑制剂。 HDAC。我们用异羟肟酸代替了衣原体的环氧酮部分，以设计有效且可逆的HDAC抑制剂。另外，对于一系列衣藻多菌素类似物系列，引入了许多氨基-环烷羧酸（Acc）而不是简单的氨基-异丁酸（Aib）。测试了所合成的化合物的HDAC抑制活性，结果表明其中许多是HDAC的有效抑制剂。用芳香族氨基酸代替衣原体的Aib残基增强了体内和体外的抑制活性。我们已经对衣原霉素-异羟肟酸类似物进行了圆二色性和分子模拟研究，并将其与衣原霉素的溶液结构进行了比较。

  Flexible Synthesis and Evaluation of Diverse Anti-Apicomplexa Cyclic Peptides

  摘要：

  A modular approach to synthesize anti-Apicomplexa parasite inhibitors was developed that takes advantage of a pluripotent cyclic tetrapeptide scaffold capable of adjusting appendage and skeletal diversities in only a few steps (one to three steps). The diversification processes make use of selective radical coupling reactions and involve a new example of a reductive carbon nitrogen cleavage reaction with SmI2. The resulting bioactive cyclic peptides have revealed new insights into structural factors that govern selectivity between Apicomplexa parasites such as Toxoplasma and Plasmodium and human cells.

  The naturally occurring cyclic tetrapeptide, chlamydocin, originally isolated from fungus , consists of alpha-aminoisobutyric acid, -phenylalanine, -proline and an unusual amino acid ()-2-amino-8-(()-oxiran-2-yl)-8-oxooctanoic acid (Aoe) and inhibits the histone deacetylases (HDACs), a class of regulatory enzymes. The epoxyketone moiety of Aoe is the key functional group for inhibition. The cyclic tetrapeptide scaffold is supposed to play important role for effective binding to the surface of enzymes. In place of the epoxyketone group, hydroxamic acid and sulfhydryl group have been applied to design inhibitor ligands to zinc atom in catalytic site of HDACs. In the research for more potent HDAC inhibitors, we replaced the epoxyketone moiety of Aoe with different functional groups and synthesized a series of chlamydocin analogs as HDAC inhibitors. Among the functional groups, methoxymethylketone moiety showed as potent inhibition as the hydroxamic acid. On the contrary, we confirmed that borate, trifruoromethylketone, and 2-aminoanilide are almost inactive in HDAC inhibition.
