Abstract:
Disclosed is the unexpected discovery that flavopiridol binds tightly to the transcription elongation factor, P-TEFb and dramatically inhibits its activity. As P-TEFb is required for HIV propagation and replication, this invention provides new methods, compositions and kits for the effective treatment of HIV infections and AIDS using flavopiridol, both alone and in combination with other therapies.
Abstract:
Smooth muscle cells (SMC) proliferation is a critical component of neointimal formation in many animal models of vascular injury, and in many human lesions as well. Cell cycle inhibition by gene transfer techniques can block SMC proliferation and lesion formation in many animal models, although these methods are not yet applicable to the treatment of human disease. Flavopiridol is a recently identified, potent, orally available cyclin-dependent kinase inhibitor. Given the role of smooth muscle cell (SMC) proliferation in vascular disease, we tested the effects of flavopiridol, a recently identified cyclin-dependent kinase inhibitor, on SMC growth in vitro and in vivo. Flavopiridol (75 nmol/L) potently blocked SMC proliferation, an effect that was associated with downregulation of cyclin-dependent kinase activity and cell cycle-related gene expression. We examined the effects of flavopiridol on SMC proliferation in vivo in the rat carotid injury model. Flavopiridol (5 mg/kg) decreased neointimal size by 35% and 39% at 7 and 14 days, respectively, after balloon injury. Flavopiridol may be a potential therapeutic tool in the treatement of SMC-rich vascular lesions. 4-H-1-benzopyran-4-one derivatives inhibit smooth muscle cell proliferation at low dosage levels.

Abstract:
A method is provided for treating hematologic tumors and solid tumors, including certain types of leukemias and metastatic tumors, having high LDL requirements employing a delipidating agent such as an MTP inhibitor to substantially reduce LDL blood levels. In addition, a method is provided for treating tumors of the above types having high LDL requirements, especially hematologic tumors such as certain leukemias, employing a delipidating compound to substantially remove native LDL, and then administering a cytotoxic agent carried in reconstituted LDL.

Abstract:
Compositions and methods for the treatment of malignancy are disclosed. Specifically, the disclosure provides a method for treating cancer comprises assessing tyrosine 88 (Y88) phosphorylation (pY88) levels in p27 in a biological sample comprising cancer cells from a subject, and stratifying pY88 phosphorylation levels as 0, 1, 2 or 3 as compared to pY88 phosphorylation levels observed in control tissues; where a level of 0 indicates no detectable sensitivity to cyclin-dependent kinase 4 (cd4k) inhibition; a level of 1, low or no detectable sensitivity; and a level of 2 or 3, indicates detectable sensitivity to cdk4 inhibition. Further provided is a kit for practicing the method.
