    • It is intended to provide a novel thiopeptide compound represented by the formula (I) obtained by subjecting a known thiopeptide compound QN3323-A substance to oximation and acylation at the 2- and 26-positions and a salt thereof. The compound has a good antimicrobial activity, particularly has an excellent antimicrobial activity against multidrug resistant bacteria such as MRSA and VRE, and is useful as a pharmaceutical, particularly an antimicrobial agent, more particularly a preventive and/or therapeutic agent for multidrug resistant bacterial infection. (I) In the formula, the symbols have the following meaning. R 1 represents lower alkyl which may have a substituent or the like; R 2 represents -ALK-COORa, -ALK- (heteroaryl which may have a substituent), -ALK- (aryl which may have a substituent), or -ALK-NRbRc; ALK represents a lower alkylene group; Ra represents H or lower alkyl; Rb and Rc are the same or different, and represent H or lower alkyl or are combined with the adjacent nitrogen atom to form a 5- to 8-membered nitrogen-containing saturated cyclic group which may have a substituent.
    • 旨在提供一种通过使已知的硫肽化合物QN3323-A物质在2-和26位进行肟化和酰化而得到的由式(I)表示的新型硫肽化合物及其盐。 该化合物具有良好的抗微生物活性,特别是抗多种药物抗性细菌如MRSA和VRE具有优异的抗微生物活性,并且可用作药物,特别是抗微生物剂,特别是用于多药耐药细菌感染的预防和/或治疗剂 。 (I)在公式中,符号具有以下含义。 R 1表示可以具有取代基的低级烷基等; R 2表示-ALK-COORa,-ALK-(可具有取代基的杂芳基),-ALK-(可具有取代基的芳基)或-ALK-NRbRc; ALK表示低级亚烷基; Ra表示H或低级烷基; Rb和Rc相同或不同,代表H或低级烷基或与相邻的氮原子结合形成可具有取代基的5至8元含氮饱和环状基团。
