PROBLEM TO BE SOLVED: To provide an acid-fast bacterium growth inhibitor.SOLUTION: The acid-fast bacterium growth inhibitor includes one or more compounds, which are selected from the group consisting of: compounds represented by general formulae (I) and (II) enantiomers of the compounds and pharmaceutically acceptable salts of the compounds, as active ingredients. In the formula (I): X1 is a radical selected from the group consisting of -CH2-P(=O)(OY)2, -Z-S(=O)2-OY, and -Z-P(=S)(OY)2. In the formula(II): X2 is a group selected from the group consisting of -Z-P(=O)(OY)2, -Z-S (=O)2-OY, and -Z-P(=S)(OY)2 Y is H or a 1-5C alkyl group and Z is O, S or CH2.COPYRIGHT: (C)2013,JPO&INPIT【課題】抗酸菌生育阻害剤を提供する。【解決手段】なお、X1は、-CH2-P(=O)(OY)2、-Z-S(=O)2-OY、-Z-P(=S)(OY)2、X2は、-Z-P(=O)(OY)2、-Z-S(=O)2-OY、-Z-P(=S)(OY)2、Yは、Hまたは炭素数1~5のアルキル基り、Zは、O、S、またはCH2である。【選択図】図1
