摘要:
Substantially pure amorphous 9-deoxo-9a-aza-9a-methyl-9a-homoerythromycin A. In addition, this disclosure is directed to a process for the preparation thereof from crude 9-deoxo-9a-aza-9a-methyl-9a-homoerythromycin A via orthorhombic isostructural pseudopolymorphs of 9-deoxo-9a-aza-9a-methyl-9a-homoerythromycin A, of the general formula I: wherein S represents a water-miscible or water-immiscible organic solvent, characterized by the orthorhombic space group P212121, with average unit cell parameters a=8.2 to 9.7 Å, b=11.5 to 13.5 Å, c=44.5 to 47.0 Å, α=β=γ=90°, wherein a, b and c represent the crystal axes lengths and α, β and γ represent the angles between the crystal axes. In addition, pharmaceutical compositions containing the substantially pure amorphous 9-deoxo-9a-aza-9a-methyl-9a-homoerythromycin A are disclosed, as well as a method for the treatment of bacterial and protozoal infections, and inflammation related diseases in humans and animals by administration of a pharmaceutical composition containing same.
摘要:
Substantially pure isostructural pseudopolymorphs of 9-deoxo-9a-aza-9a-methyl-9a-homoerythromycin A having the Formula I: wherein S is an organic solvent which is at least partially miscible with water, x is 1, 1.25, 1.5 or 2, y is 0, 0.5, or 1, the pseudopolymorph being characterized by the monoclinic space group P21 and average unit cell parameters comprising: crystal axis lengths of a=15.5-17.0 Å, b=15.5-17.0 Å, and c=17.5-19.5 Å, and angles between the crystal axes of α=γ=90° and β=106°-112°. In addition, this disclosure is directed to processes for the preparation of the substantially pure isostructural pseudopolymorphs of Formula I; to pharmaceutical compositions containing substantially pure isostructural pseudopolymorphs of Formula I; and to a method for the treatment of bacterial and protozoan infections, and inflammation-related diseases by administration of a pharmaceutical composition containing the substantially pure isostructural pseudopolymorphs of Formula I.
