Compounds represented by the formula [1]
R1 is H or a substituent; R2 and R3 are C1-C3 alkyl; R4 is siderophore group e.g. CH3—(CH2)n—C(O)—N(OH)—(CH2)m— with n=10-22, m=2-6; X is O, S, or NH; X1 is O or NH; Y is H or alkyl; Z is H or substituted amino, e.g., t-BocNH or CbzNH, and r is 2-4; are useful in the method provided for treating tuberculosis. [1] is prepared by coupling [7], wherein HX1 is HO— or H2N—,
with [4] obtained as the free acid after saponification of the methyl ester.
由公式表示的化合物:[1]中,R1为H或取代基;R2和R3为C1-C3烷基;R4为铁载体基团,例如CH3—(CH2)n—C(O)—N(OH)—(CH2)m—,其中n=10-22,m=2-6;X为O、S或NH;X1为O或NH;Y为H或烷基;Z为H或取代氨基,例如t-BocNH或CbzNH,r为2-4;在治疗结核病的方法中是有用的。[1]是通过偶联[7]制备的,其中HX1为HO—或H2N—,与作为甲酯皂化后得到的[4]结合而成的自由酸。
