The present invention provides a 2,3-dihydro-6-nitroimidazo[2,1-b]oxazole compound represented by the following general formula:
wherein R1 represents a hydrogen atom or C1-C6 alkyl group, n represents an integer of 0 to 6, R2 represents a group —OR3 or the like, and R3 represents a hydrogen atom, C1-C6 alkyl group or the like, or R1 and —(CH2)nR2 may bind to each other together with carbon atoms adjacent thereto through nitrogen atoms so as to form a spiro ring represented by the general formula (H):
wherein R41 is hydrogen, C1-C6 alkyl group or the like. The present compound has an excellent bactericidal action against Mycobacterium tuberculosis, multi-drug-resistant Mycobacterium tuberculosis, and atypical acid-fast bacteria.
本发明提供一种由以下通式表示的2,3-二氢-6-硝基咪唑并[2,1-b]噁唑化合物:其中R1代表氢原子或C1-C6烷基,n代表0到6的整数,R2代表-OR3基团或类似基团,R3代表氢原子、C1-C6烷基或类似基团,或R1和-(CH2)nR2可以与相邻的碳原子通过氮原子结合在一起,形成由通式(H)表示的螺环:其中R41是氢、C1-C6烷基或类似基团。该化合物对结核分枝杆菌、多药耐药结核分枝杆菌和非典型酸性快速菌具有优异的杀菌作用。
