Promising potential chemotherapeutics for the treatment of cancer can be developed from farnesyltransferaseinhibitors. A novel class of modular bisubstratefarnesyltransferaseinhibitors is presented that can be synthesized in a straightforward manner. An example of such an inhibitor is compound 1, which has an IC50 value of 3.7 μM.

The arylomycins are a class of natural product antibiotics that inhibitbacterial type Isignalpeptidase and are under development as therapeutics. Four classes of arylomycins are known, arylomycins A–D. Previously, we reported the synthesis and analysis of representatives of the A, B, and C classes and showed that their spectrum of activity has the potential to be much broader than originally assumed
芳霉素是一类天然产物抗生素,可抑制细菌 I 型信号肽酶,正在开发作为治疗剂。已知四类芳霉素,芳霉素 A-D。之前,我们报告了 A、B 和 C 类代表的综合和分析,并表明它们的活动范围可能比最初假设的要广泛得多。连同获得性和先天性耐药机制的比较,这使我们认为 arylomycins 是潜在的抗生素,曾经具有广谱活性的抗生素,但在今天的检查中,由于先前的选择而只有窄谱活性在与其他首先推动它们进化的微生物竞争的过程中产生抗药性。有趣的是,放线菌素,据报道,芳霉素 D 类中唯一确定的成员具有抗 MRSA 的活性。为了证实和理解这种活性,合成了几种放线菌素衍生物。我们证明先前报告的放线菌素结构不正确,确定可能是正确的支架,确认支架具有抗 MRSA 的活性,并确定此活动的起源。
