  摘要：

  已经制备了辅酶A（CoA）和CoA硫酯的类似物，其中最接近硫醇基的酰胺键已被修饰。其中的酰胺键被酯键取代的乙酰基-CoA的类似物是肉碱乙酰基转移酶，氯霉素乙酰基转移酶和柠檬酸合酶的良好底物，其K（m）值比后者高2至8倍。乙酰基CoA和V（max）值是天然底物的14％至> 80％。在酰胺键和硫醇基团之间插入了额外亚甲基的类似物，与三种酶的结合力降低了不到4倍，但相对于带有肉碱乙酰基转移酶的乙酰辅酶A而言，活性却低于1％，而对乙酰辅酶A则没有可测量的活性。其他两种酶。几种CoA硫酯的类似物（其中酰胺键被半硫缩醛键取代）没有显示出用适当的酶可测量的活性。结果表明，酰胺键的某些方面以及该酰胺与硫醇/硫酯部分之间的适当距离对于利用CoA酯的酶的活性至关重要。

  Synthesis of Novel Analogs of Acetyl Coenzyme A: Mimics of Enzyme Reaction Intermediates

  摘要：

  An improved method for the synthesis of analogs of coenzyme A (CoA) and its thioesters, which are modified in the thiol or thioester moiety, has been developed using a combination of chemical and enzymatic reactions, The enzymes catalyzing the last two steps of CoA biosynthesis were used to prepare a CoA analog (1c) in which an amide bond is replaced by a thioester bond and the thiol group is replaced by a methyl group. Reaction of 1c with a primary amine in aqueous solution results in aminolysis of the thioester linkage to form the desired CoA analog. Reaction with different amines permits the introduction of a variety of functional groups in place of the nor mal thiol or thioester group. This methodology has been used in the synthesis of five new analogs of acetyl-CoA in which the thioester sulfur is replaced by a methylene group and the acetyl group is replaced by carboxylate (14a), nitro (14b), carboxamide (14c), methyl sulfoxide (14d), and methyl sulfone (14e) groups. 14a-c were designed to mimic the possible enolate or enol intermediate in the reaction of citrate synthase and related enzymes. 14a and 14c are potent inhibitors of citrate synthase, with K-i values 1000- and 570-fold lower than the K-m for acetyl-CoA, respectively. CD titrations indicate that 14a and 14c have low affinity for citrate synthase in the absence of oxaloacetate, consistent with their recognition as enol or enolate analogs. 14b is a poor inhibitor of citrate synthase, with affinity slightly lower than that for acetyl-CoA. These results are consistent with generation of the enol form of acetyl-CoA as the nucleophilic intermediate in the reaction of citrate synthase. 14d and 14e were designed to mimic the tetrahedral intermediate or transition state in the reaction of chloramphenicol acetyltransferase and related acetyl-CoA-dependent acetyltransferases. Both compounds are poor inhibitors of chloramphenicol acetyltransferase, with affinities slightly lower than that of acetyl-CoA, indicating that these compounds are not good mimics of the enzyme-bound tetrahedral intermediate or transition state.

• A Reversed Thioester Analogue of Acetyl-Coenzyme A:  An Inhibitor of Thiolase and a Synthon for Other Acyl-CoA Analogues
  作者：Kurt W. Vogel、Dale G. Drueckhammer

  We have previously reported a general synthetic approach to analogues of coenzyme A (CoA) and CoA esters using a combination of enzymatic and nonenzymatic reactions (Martin et al. J. Am. Chem. Sec. 1994, 116, 4660). We report here the extension of this method to a CoA ester analogue 1c in which the orientation of the thioester is reversed. A key to this synthesis is the use of a trithioortho ester as a protected thioester. The reversed thioester analogue Ic is a time-dependent inhibitor of thiolase, apparently forming an acyl enzyme in which the CoA moiety rather than an acetyl moiety is covalently attached to an active site nucleophile. This analogue also serves as a general synthon for analogues having other functionality at the site of the thioester group. This has been applied to the synthesis of a reversed thioester analogue of succinyl-CoA 6 and hydroxamate 7 and hydrazide 8 analogues of acetyl-CoA, analogues which are not available by the previously described methodology. The hydroxamate and hydrazide analogues are potent inhibitors of the enzyme citrate synthase. The reversed thioester analogue of acetyl-CoA may have useful applications in enzymology and permits the ready access to a range of additional CoA analogues modified in the thioester moiety.
