  Antibacterial 5′-O-(N-dipeptidyl)-sulfamoyladenosines

  摘要：

  The aminoacyl-tRNA synthetase (aaRS) class of enzymes is a validated target for antimicrobial development. Aminoacyl analogues of 5'-O-(N-L-aminoacyl)-sulfamoyladenosines are known to be potent inhibitors of aaRS, but whole cell antibacterial activity of these compounds is very limited, and poor penetration into bacteria has been proposed as the main reason for this. Aiming to find derivatives that better penetrate bacteria, we developed a simple and short method to prepare dipeptidyl-derivatives of 5'-O-(N-L-aminoacyl)-sulfamoyladenosines, and used this method to prepare 18 5'-O-(N-dipeptidyl)-sulfamoyladenosines. The antibacterial activity of these derivatives and a number of reference compounds against S. aureus, E. faecalis and E. coli was determined. Several of the new derivatives showed improved antibacterial activity and an altered spectrum of antibacterial activity. (C) 2008 Elsevier Ltd. All rights reserved.

  The invention provides an improved method of macrocyclization of peptidomimetics, as measured by isolated yields and product distribution, which comprises substitution of one or more of the backbone amide C=O bonds with a turn-inducing motif. The method is general with enhancements seen across a range of ring sizes (e.g. tri-, tetra-, penta- and hexapeptides). Specifically, the invention provides a peptidomimetic macrocycle comprising a carbonyl bioisosteric turn-inducing element having the structure: (I) wherein X is a heteroatom; and wherein R1 to R6 are each independently selected from alkyl, aryl, heteroaryl and H.

  bacterial ribosome and inhibits peptide bond formation. As an approach for modifying and potentially improving properties of this inhibitor, we explored ribosome binding and inhibitory activity of a number of amino acid analogs of CHL. The L-histidyl analog binds to the ribosome with the affinity exceeding that of CHL by 10 fold. Several of the newly synthesized analogs were able to inhibit protein synthesis

  抗生素氯霉素（CHL）以中等亲和力结合在细菌核糖体的肽基转移酶中心，并抑制肽键的形成。作为修饰和潜在改善该抑制剂性质的方法，我们探索了核糖体结合和许多CHL氨基酸类似物的抑制活性。L-组氨酸类似物以超过CHL十倍的亲和力与核糖体结合。一些新合成的类似物能够抑制蛋白质合成，并表现出不同于CHL的作用方式。然而，半合成CHL类似物的抑制特性与其亲和力不相关，并且一般而言，与原始抗生素相比，CHL的氨基酸类似物是不太有效的翻译抑制剂。与三个半合成类似物复合的嗜热栖热菌70S核糖体显示，CHL衍生物在肽基转移酶中心结合，在那里被测化合物的氨酰基部分与rRNA建立了特异相互作用。尽管仍然是效率低下的翻译抑制剂，但合成的化合物仍代表着有前途的化学支架，其靶向核糖体的肽基转移酶中心，并可能适合进一步研究。
