Despite extensive functional screening of the bacterial RNA polymerase (RNAP) over the past years, very few novel inhibitors have been reported. We have, therefore, decided to screen with a radically different, non-enzymic, protein-protein interaction assay. Our target is the highly conserved RNAP-sigma interaction that is essential for transcription.
Small molecule inhibitors of the RNAP-sigma interaction were tested for their activity on transcription and on bacteria.
These compounds have antibacterial activity against Gram-positive bacteria including multiresistant clinical isolates.
This is, to our knowledge, the first example of a small molecule inhibitor of this interaction.
尽管在过去几年中对细菌RNA聚合酶(RNAP)进行了广泛的功能筛选,但报道的新型抑制剂却非常少。因此,我们决定采用一种截然不同的非酶促蛋白质-蛋白质相互作用检测方法进行筛选。我们的目标是高度保守的RNAP-σ相互作用,它对转录至关重要。
测试了RNAP-σ相互作用的小分子抑制剂对转录和细菌的活性。
这些化合物对革兰氏阳性菌具有抗菌活性,包括多重耐药临床分离株。
据我们所知,这是这种相互作用的小分子抑制剂的首个实例。
