Novel 1-N-acylated or 1-N-alkylated derivatives of a 4-O-substituted-2-deoxystreptamine aminoglycoside selected from the group consisting of;
apramycin,
a or β-(C1 to C6 alkyl)aprosaminide,
a or β-(C2 to C6 hydroxyalkyl)aprosaminide,
a or β-(C2 to C6 aminoalkyl)aprosaminide,
a or β-(C2 to C6 protected aminoalkyl) aprosaminide, a or
β-(C3 to C6 aminohydroxyalkyl)-aprosaminide, a or β-(C3 to C6 (protected amino)hydroxyalkyl)aprosaminide, and
pharmaceutically-acceptable acid addition salts thereof are disclosed. They are useful for
treating warm blooded animals suffering from bacterial diseases. They and 1-N-acylated and 1-N-alkylated derivatives of lividamine, paromamine and the 6'-N-protected derivatives of nebramine, neamine, gentamine C1, gentamine C1a, gentamine C2, gentamine C2a, and gentamine C2b, and pharmaceutically-acceptable acid addition salts thereof can be prepared by reacting the corresponding aminoglycoside substrate with a zinc salt Zn (X2), X being C, to C10 carboxylate, in water, diluting with a polar organic solvent, treating with an alkalating agent or acylating agent, optionally, deprotecting the amino or N-protected substituents, optionally, reducing carbonyl portions of an acyl group, and recovering as a free base or as a pharmaceutically-acceptable acid addition salt.
