##STR1## in which: B represents a hydrogen atom or a lower acyl group,

Macrolide compounds

Compounds of general formula: ##STR1## where A, B, G, R.sub.2, R.sub.3, R.sub.4 and  are defined in the description. Medicinal products comprising a compound of the invention and useful in the treatment of bacterial infections are also disclosed.

Tylosin derivatives

Novel aminoglycoside-aminocyclitol derivatives corresponding to the general formula: ##STR1## wherein R.sub.1 and R.sub.2, which are different, represent hydrogen or CH.sub.2 NH.sub.2 and R is selected from the group consisting of: ##STR2## wherein R.sub.3 represents NH.sub.2 or OH and R.sub.4 represents ##STR3## wherein R.sub.5 represents hydrogen or methyl and the pharmaceutically acceptable acid addition salts thereof. They are useful as antibiotics.

Aminoglycoside-aminocyclitol derivatives and method of use

Cyclohexanediol derivatives of the general formula: ##STR1## wherein R.sub.1 and R.sub.2, which are identical, each represent a N.sub.3 or NH.sub.2 group, and the acid addition salts of the derivative containing two NH.sub.2 groups. These compounds are useful as intermediate products for the preparation, for example, of synthetic antibiotics.

Alicyclic compounds

Cyclohexanediol derivatives of the general formula: ##SPC1## Wherein R.sub.1 and R.sub.2, which are identical, each represent a N.sub.3 or NH.sub.2 group, and the acid addition salts of the derivative containing two NH.sub.2 groups. These compounds are useful as intermediate products for the preparation, for example, of synthetic antibiotics.
