PENTACYCLINE DERIVATIVES FOR THE TREATMENT OF INFECTIONS
The tetracycline class of antibiotics has played a major role in the treatment of infectious diseases for the past 50 years. However, the increased use of the tetracyclines in human and veterinary medicine has led to resistance among many organisms previously susceptible to tetracycline antibiotics. The modular synthesis of tetracyclines and tetracycline analogs described provides an efficient and enantioselective route to a variety of tetracycline analogs and polycyclines previously inaccessible via earlier tetra-cycline syntheses and semi-synthetic methods. These analogs may be used as anti-microbial agents or anti-pro liferative agents in the treatment of diseases of humans or other animals.

Tetracycline compositions
Aqueous solutions of tetracycline or salts thereof, a pharmaceutically acceptable soluble magnesium compound and 2-pyrrolidone as a co-solvent, said solution having a pH of 7.5 to 9.5 and being useful as an injectable composition combining low viscosity, high potency, good clarity and good stability.
