  Chlamydocin analogs bearing carbonyl group as possible ligand toward zinc atom in histone deacetylases

  摘要：

  A series of chlamydocin analogs with various carbonyl functionalities were designed and synthesized as histone deacetylase (HDAC) inhibitors. Chlamyclocin is a cyclic tetrapeptide containing an epoxyketone surrogate in the side chain which makes it irreversible inhibitor of HDACs, whereas apicidins are a class of cyclic tetrapeptides that contain an ethylketone moiety as zinc ligand. We replaced the epoxyketone moiety of chlamydocin with several ketones and aldehyde to synthesize potent reversible and selective HDAC inhibitors. The inhibitory activity of the cyclic tetrapeptides against histone deacetylase enzymes were evaluated and the result showed most of them are potent inhibitors. Some of them have remarkable selectivity among the HDACs. (c) 2006 Published by Elsevier Ltd.

  RETRACTED: Design and synthesis of CHAP31, trapoxin B and HC-toxin based bicyclic tetrapeptides disulfide as potent histone deacetylase inhibitors

  摘要：

  The naturally occurring cyclic depsipeptide, FK228 inhibits histone deacetylase (HDAC) enzymes after reductive cleavage of intra-molecular disulfide bond. One of the sulfhydryl groups produced in the reduction interacts with zinc atom that involved in the catalytic mechanism of type 1 and 2 HDACs such as HDAC1, HDAC4, and HDAC6. In the present study, we describe the development of CHAP31, trapoxin B and HC-toxin based cyclic tetrapeptides with intra-molecular disulfide bond as HDAC inhibitors. The bicyclic tetrapeptides disulfide showed potent HDAC1 and HDAC4 inhibition and p21 promoting activity.

  Chlamydocin-hydroxamic acid analogues were designed and synthesized as histone deacetylase (HDAC) inhibitors based on the structure and HDAC inhibitory activity of chlamydocin and trichostatin A. Chlamydocin is a cyclic tetrapeptide containing an epoxyketone moiety in the side chain that makes it an irreversible inhibitor of HDAC. We replaced the epoxyketone moiety of chlamydocin with hydroxamic acid to

  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。
