  • Publication number: 20080091008
    Abstract: A process for preparing a crystalline rapamycin analog includes: combining the rapamycin analog with an organic medium to form a mixture; incubating the mixture until the rapamycin analog crystallizes; and recovering the crystalline rapamycin analog. The organic medium can be a solvent, and the process can include causing the rapamycin analog to dissolve into the solvent, and incubating the solvent until the rapamycin analog crystallizes. The following can also be performed: forming a slurry of crystalline rapamycin analog; stirring the rapamycin analog mixture until the rapamycin analog crystallizes; saturating the rapamycin analog solution; forming a supersaturated rapamycin analog solution; combining an antisolvent with the rapamycin analog and the solvent to form a biphasic mixture, and incubating the biphasic mixture to cause a liquid-liquid phase split.

  • Publication number: 20070104780
    Abstract: A pharmaceutical composition comprises a drug-carrier system having a small-molecule drug of low water solubility, e.g. N-[4-(3-amino-1H-indazol-4-yl)phenyl]-N?-(2-fluoro-5-methylphenyl)urea (ABT-869), and (+)-1-(5-tert-butyl-1-yl)-3-(1H-indazol-4-yl)-urea (ABT-102), in solution in a substantially non-aqueous carrier that comprises at least one phospholipid and a pharmaceutically acceptable solubilizing agent. The drug-carrier system, when mixed with an aqueous phase, typically forms a non-gelling, substantially non-transparent liquid dispersion. The composition is suitable for administration by a suitable route, e.g. orally, to a subject in need thereof.
