REVERSIBLE BORONATE COMPLEXES OF 1,2-$i(CIS)-DIOL CYCLIC-PEPTIDES

摘要

Reversible borate or boronate complexes of 1,2-cis-diol cyclic-peptides and their use as a means for purification, isolation, stabilization and/or water solubilization of their respective parent 1,2-cis-diol cyclic-peptide is described. A method for forming the boronate adducts is also described. The method is particularly useful for forming boronate adducts of hydrophobic Echinocandin compounds to increase their water solubility. Pharmaceutical formulations and treatments based on the reversible borate or boronate complexes of active 1,2-cis-diol cyclic-peptides (e.g., Echinocandin antifungal compounds) are also described.
