The present invention relates to methods of treating cancer using a combination of a compound which is a PSA conjugate and a compound which is a inhibitor of prenyl-protein transferase, which methods comprise administering to said mammal, either sequentially in any order or simultaneously, amounts of at least two therapeutic agents selected from a group consisting of a compound which is a PSA conjugate and a compound which is a inhibitor of prenyl-protein transferase. The invention also relates to methods of preparing such compositions.
The present invention comprises piperazine/piperazinone-containing compounds having multicyclic ring system substituents on one of the piperazine/piperazinone nitrogens, which inhibit prenyl-protein transferases, including farnesyl-protein transferase and geranylgeranyl-protein transferase type I. Such therapeutic compounds are useful in the treatment of cancer.
The present invention is directed toward a GGTase-I competitive binding assay which can be used to determine the relative GGTase-I inhibitory potency of test compounds. The present invention is also directed toward radiolabeled geranylgeranyl-protein transferase type-I inhibitor compounds which are useful to label GGTase-I in assays, whether cell-based, tissue-based or in whole animal.
The present invention is related to a drug delivery device, that is pH insensitive, for the sustained in situ production and release of a dispersion, in an environment of use, which comprises
a) a compressed core prepared from an admixture comprising
i) a therapeutically effective amount of a beneficial agent that has a solubility profile that is dependent on the pH level of the environment of use;
ii) a water swellable polymer which upon hydration forms gelatinous microscopic particles; and
iii) a pH modulator; and
b) a water insoluble, water impermeable polymeric coating comprising a polymer and a plasticizer, which surrounds and adheres to the compressed core, said water insoluble, water impermeable polymeric coating having at least one aperture.
