SB-219383 is a naturally occurring antibiotic, which acts by inhibition of tyrosyl tRNA synthetase. Semi-synthetic derivatives of SB-219383 were prepared with the objective of elucidating the key features required for inhibition of tyrosyl tRNA synthetase in order to improve the antibacterial activity. Some ester and amide derivatives as well as monocyclic analogues exhibited sub-nanomolar inhibitory activity against tyrosyl tRNA synthetase.
SB-219383 是一种天然抗生素,通过抑制酪氨酸 tRNA 合成酶发挥作用。我们制备了 SB-219383 的半合成衍生物,目的是阐明抑制酪氨酸 tRNA 合成酶所需的关键特征,以提高其抗菌活性。一些酯类和酰胺类衍生物以及单环类似物对酪氨酸 tRNA 合成酶具有亚纳摩尔抑制活性。
