Compounds of the formula: ##STR1## wherein R is H, Cl, F, Br, I or R.sub.1 S--, in which R.sub.1 is C.sub.1 -C.sub.10 linear or branched chain alkyl or halogenated linear or branched chain alkyl, and wherein R.sub.2, R.sub.3 and R.sub.4 are the same or different and each is H-- or --OH, with the proviso that at least one of R.sub.2, R.sub.3 and R.sub.4 is hydroxy and the further proviso that when R.sub.2, R.sub.3 and R.sub.4 are all OH, R.sub.1 is other than methyl, are useful in inhibiting the growth of MTR kinase-dependent microorganisms and parasitic protazoans. The compounds wherein R is R.sub.1 S are novel, except those wherein R.sub.1 is methyl or isobutyl when R.sub.2, R.sub.3 and R.sub.4 are all OH.
化合物的公式为:##STR1## 其中R为H、Cl、F、Br、I或R.sub.1 S--,其中R.sub.1为C.sub.1-C.sub.10线性或支链烷基或卤代线性或支链烷基,且R.sub.2、R.sub.3和R.sub.4相同或不同,每个都是H--或--OH,但至少其中一个为羟基,且进一步规定当R.sub.2、R.sub.3和R.sub.4都是OH时,R.sub.1不是甲基时,这些化合物对抑制
MTR激酶依赖的微
生物和寄生原虫的生长有用。其中R为R.sub.1 S的化合物是新颖的,除了当R.sub.2、R.sub.3和R.sub.4都是OH时,R.sub.1为甲基或异丁基的化合物。
