The application of natural product inspired synthesis has identified novel antibacterial tetramic acids which exhibit wide ranging antibacterial activity, and which provide potential lead structures for antibacterial drug discovery. Their phenotypic activity appears to correlate with action at two enzymes, UPPS and RNAP, which operate in independent metabolic pathways. SAR maps and identification of their relevant binding sites by molecular modelling has been achieved, and characterisation of the most active compounds suggests that these systems offer potential for topical antibiotics but that for oral and injectable use further optimisation is required.
天然产物启发合成的应用已经发现了新的抗菌四氨基酸,这些化合物表现出广泛的抗菌活性,并为抗菌药物的研发提供了潜在的领先结构。它们的表型活性似乎与两个酶的作用有关,分别是UPPS和RNAP,这两个酶在独立的代谢通路中运作。通过分子建模已实现SAR图谱及其相关结合位点的鉴定,且对最活性化合物的特征分析表明,这些系统在局部抗生素方面具有潜力,但对于口服和注射使用则需要进一步优化。
