Anti-cancer activity of carvedilol and its isomers
InactiveUS6632832B1Inhibits COX activityPrevent and inhibit tumor growthBiocideArtificial cell constructsMelanomaProstate cancer
The present invention provides for pharmaceutical compositions comprising carvedilol for treatment of cancer. More particularly the invention relates to the use of carvedilol for treatment of cancers of the colon, ovary, breast, prostate, pancreas, lung, melanoma, glioblastoma, oral cancer and leukemias. Although not bound to any theory, the anticancer activity of carvedilol appears to be attributed to the inhibition of Epidermal Growth Factor and Platelet derived growth factor dependent proliferation of cancer cells. Further, carvedilol exerts anticancer effect by inhibition of the Protein kinase C (PKC) activity and that of the cyclooxygenase 2 enzyme. The invention also relates to the anticancer activity of the optically pure isomers S(-) and R(+) of carvedilol and the use of carvedilol and its isomers in pharmaceutical compositions for the treatment of cancer.< / PTEXT>
