  • Publication number: 20180015066
    Abstract: Compositions which comprise a hydro-phobic taxane such as paclitaxel are produced by non-covalent complexing between the taxane and alpha-fetoprotein c at a ratio of about 4 moles of taxane per mole of AFP. The complexes are water soluble and suitable for injection. Uses of the compositions for treating a subject presenting with an AFP receptor positive and taxane responsive ease cell are also disclosed.

  • Patent number: 6949521
    Abstract: Pharmaceutical prodrug compositions are provided comprising azide derivatives of drugs which are capable of being converted to the drug in vivo. Azide derivatives of drugs having amine, ketone and hydroxy substituents are converted in vivo to the corresponding drugs, increasing the half-life of the drugs. In addition azide prodrugs are often better able to penetrate the blood-brain barrier than the corresponding drugs. Especially useful are azide derivatives of cordycepin, 2?-F-ara-ddI, AraA, acyclovir, penciclovir and related drugs. Useful azide prodrugs are azide derivatives of therapeutic alicyclic amines, ketones, and hydroxy-substituted compounds, including aralkyl, heterocyclic aralkyl, and cyclic aliphatic compounds, where the amine or oxygen moiety is on the ring, or where the amine or oxygen moiety is on an aliphatic side chain, as well as therapeutic purines and pyrimidines, nucleoside analogs and phosphorylated nucleoside analogs.
