Colloidal compositions, loaded with non-covalently bonded antibiotics, can be efficiently used for the treatment of severe bacterial pneumonia and other serious lung infections such as tuberculosis. Such formulations, comprised of biodegradable nanoparticles or nanocapsules with incorporated antibiotics, show a significant increase in antibacterial activity, extended and sustained drug release and a decrease in frequency of the drug administration. Antibiotics of various types, such as aminoglycosides, glycopeptides and others can be successfully incorporated into a nanoparticulate colloidal delivery system.

The present invention is directed to analogs of aminoglycoside compounds as well as their preparation and use as prophylactic or therapeutics against microbial infection.

A method of synthesizing 4-R-substituted anthracyclines and their corresponding salts from 4-demethyldaunorubicin includes the steps of treating 4-demethyldaunorubicin with a sulfonylating agent to form 4-demethyl-4-sulfonyl-R3-daunorubicin. 4-Demethyl-4-R3-sulfonyl-daunorubicin is then subject to a reducing agent in the presence of a transition metal catalyst in a temperature range of about 30° C. to about 100° C. in a polar aprotic solvent in an inert atmosphere. Protected 4-demethoxy-4-R-daunomycin then undergoes hydrolysis in a basic solution to form the 4-R-substituted anthracyclines. The novel method lacks the step of forming a stereospecific glycoside bond between aglycone and aminoglycoside. The method also increases the yield of the final product up to 30 to 40%.
