Abstract: A method of reducing the in vivo viability of cancer cells selected from the group consisting of breast cancer cells, lung cancer cells, prostate cancer cells and melanoma cancer cells has steps of: a) identifying a prospective patient having cancer cells selected from the group consisting of breast cancer cells, lung cancer cells, prostate cancer cells and melanoma cancer cells; and b) administering a cisplatin derivative to the prospective patient so that the cisplatin derivative will contact the cancer cells; wherein the cisplatin derivative is a 4,4?-bis[RO]-2,2?-bipyridine)PtCl2 where, R is selected from the group consisting of —(CH2)nCH3 where n=2, 3, 4 or 5, and —(CH2)n[O(CH2)m]yO(CH2)zCH3 where n=2, m=2, y=2, z=1. A novel synthetic process for the manufacture of these compounds (and their analogs) is also provided.

Abstract: A method and a resulting communication cable is disclosed which provides multiple degrees of control of fluid wicking propensity within the interior of the cable by impregnating the cable with a sealing composition and curing the sealing composition therein. The cable includes a central strata, a penultimate strata and an ultimate strata concentrically disposed. The central strata includes a central signal transmission medium circumscribed by a dielectric having an etched exterior surface. The penultimate strata includes a braided conductor circumscribing the dielectric and an inner jacket surrounding the braided conductor and including an etched exterior surface. The penultimate strata further includes at least one non-continuous zone of sealing composition impregnated into the braided conductor and bonding with the etched exterior surface of the dielectric. The ultimate strata includes a braided sheath circumscribing the inner jacket and an outer jacket surrounding the braided sheath.

Abstract: The specification describes a methylation resin comprising methyl(dialkyl)anilinium salts or methyl(diaryl)anilinium salts covalently bonded to the resin. The methylation resin is used in the solid-phase synthesis of codeine from morphine. Accordingly, the specification describes a process for methylating morphine to form codeine by loading morphine onto a methylation resin comprising methyl(dialkyl)anilinium salts or methyl(diaryl)anilinium salts covalently bonded to the resin; contacting the loaded resin with sufficient hydrocarbon or ether solvent to cover the loaded resin; and heating the loaded resin in the hydrocarbon or ether solvent under sufficient conditions to form codeine. The methylating resin may be used to methylate phenolic moieties on other compounds and to esterify compounds containing carboxylic acid moieties.

Abstract: A process for extracting morphine from opium is described. In the process, opium is extracted with a basic alcoholic solution. The basic alcoholic solution is filtered and the alcohol removed from the filtrate to leave a residue. The residue is then extracted with a basic aqueous solution having a pH of at least 11. The basic aqueous solution may be filtered to remove any solid matter remaining after the aqueous extraction step, and then be stirred with a sufficient amount of a salt to avoid emulsion formation. The basic aqueous solution or filtrate is then extracted with benzene or toluene. Next, adjusting the pH of the basic aqueous filtrate to pH 8.5 to 9.5 allows the morphine to precipitate and be recovered.
