The rifamycins are a group of antibiotics that are synthesized either naturally by the bacterium Amycolatopsis rifamycinica or artificially. They are a subclass of the larger family of ansamycins. Rifamycins are particularly effective against mycobacteria, and are therefore used to treat tuberculosis, leprosy, and mycobacterium avium complex (MAC) infections. Webanalyzing the initiation of RNA synthesis at one of the known promoter sites of phage A, these authors found that rifampin leads to abortive initiation-i.e., to the formation of the dinucleo-tide pppApU-and inhibits the formation of the second phosphodiester bond. A model was pro-posed in which the binding of rifampin to RNA WebApr 12, 2024 · The synthesis of DESs is hassle-free. In most cases, a DES is created by combining a quaternary ammonium or phosphonium salt with a hydrogen-bond donor, resulting in a new liquid phase with a melting point lower than the melting point of either individual component (Naik et al., 2024, Hou et al., 2024). penny ishmael
