    • Compounds of the formula ##STR1## wherein R.sub.1 is lower alkyl, lower alkoxycarbonyl-lower alkyl, phenyl, phenyl substituted by one or more lower alkyl or halogen, phenyl-lower alkyl optionally substituted in its side chain by lower alkyl or lower alkoxycarbonyl, thienylmethyl or thiazolyl, R.sub.2 is hydrogen or lower alkyl, or ##STR2## constitutes a 3-7-membered nitrogen-containing heterocyclic ring in which R.sub.1 and R.sub.2 are connected, R.sub.3 is hydrogen or hydroxyl, and X is oxygen or sulfur, or a non-toxic salt thereof. These compounds have stronger antibacterial activity as compared with known clinically used macrolide antibiotics such as erythromycin, oleandomycin, josamycin and leucomycin, and also have strong antibacterial activity against all macrolide antibiotic-resistant strains such as macrolide-resistant A group strains (clinical isolates or erythromycin, oleandomycin and 16-membered macrolide antibiotic resistant strains). These compounds are also stable in vivo and hence may be used for treatment of infectious diseases and also are useful for feed additives and growth stimulants.
    • 其中R 1是低级烷基,低级烷氧基羰基 - 低级烷基,苯基,被一个或多个低级烷基或卤素取代的苯基,在其侧链中被低级烷基或低级烷氧基羰基任意取代的苯基 - 低级烷基,噻吩基甲基 或噻唑基,R2是氢或低级烷基,或者“IMAGE”构成其中R1和R2连接的3-7元含氮杂环,R3是氢或羟基,X是氧或硫, 其盐酸盐。 这些化合物与已知的临床使用的大环内酯类抗生素如红霉素,木兰霉素,喜马霉素和精氨酸霉素相比具有更强的抗菌活性,并且对所有大环内酯抗生素抗性菌株如大环内酯抗性A组菌株(临床分离株或红霉素)具有强抗菌活性 ,木兰霉素和16-元大环内酯抗生素抗性菌株)。 这些化合物在体内也稳定,因此可用于治疗感染性疾病,并且还可用于饲料添加剂和生长兴奋剂。

    • Compounds of the formula ##STR1## wherein R.sub.1 is optionally substituted phenyl, thienyl, 2-amino-4-thiazolyl or 2-chloroacetamido-4-thiazolyl; A is lower alkylene, lower alkenylene, or lower alkylene substituted by lower alkyl, amino, lower alkoxyimino or phenyl-Z-group wherein Z is a single bond or --S-- or --SO.sub.2 --, but when R.sub.1 is 2-amino-4-thiazolyl or 2-chloroacetamido-4-thiazolyl then A is lower alkylene substituted by lower alkoxyimino; R.sub.2 is hydrogen or hydroxyl; X is oxygen or sulfur and n=0 or 1, or a non-toxic salt thereof. These compounds have a stronger antibacterial activity against Gram positive bacteria as compared with known macrolide antibiotics such as erythromycin and tylosin, and also have an equivalent level of antibacterial activity against Gram negative bacteria as compared with that of erythromycin, and hence may be useful for clinical use. These compounds are also useful for feed additives and growth stimulants.
