Abstract:
Disclosed are compounds which are conjugates of (a) a moiety capable of localizing in the cells of a tumor or atheroma and (b) a moiety capable of catalyzing the production of reactive oxygen species from a cellular metabolite. The disclosed compounds which are useful for treating atheroma, tumors and other neoplastic tissue.
Abstract:
Texaphyrin metal complex-oligonucleotide and -oligonucleotide analog conjugates are provided where the texaphyrin is bound to an internal linkage of the oligonucleotide or oligonucleotide analog, the conjugates having catalytic activity for the hydrolysis of ribonucleic acid. Further, conjugates demonstrating catalytic turnover are described, the conjugates being especially effective under conditions where the concentration of RNA target exceeds that of available conjugate.
Abstract:
Methods for cancer chemosensitization are provided. Texaphyrins are new chemosensitizers for enhancing the cytotoxicity of chemotherapeutic agents. The enhancement appears to be P-glycoprotein-independent since texaphyrins are effective in both a P-glycoprotein-expressing and a P-glycoprotein-nonexpressing cell line. Methods are provided for the treatment of cancers such as leukemia, lymphoma, carcinoma, and sarcoma using a texaphyrin as a chemosensitizer.
Abstract:
A particular class of metal complexes, specifically certain texaphyrin metal complexes, which both hydrolyze and photocleave ribonucleic acid, and which also both hydrolyze ribonucleic acid and photocleave deoxyribonucleic acid, is provided. The texaphyrin metal complex for each set of reactions has catalytic activity for phosphate ester hydrolysis and is photosensitive. A complex having the advantage of multiple activities can result in lower treatment dosages and lower treatment costs.
Abstract:
Methods of cleavage of a polymer of deoxyribonucleic acid using photosensitive texaphyrins are disclosed. A preferred method of use is the site-specific cleavage of a polymer of deoxyribonucleic acid, and a preferred texaphyrin is a derivatized texaphyrin having binding specificity, in particular, a texaphyrin covalently coupled to a site-directing molecule, preferably an oligonucleotide.
Abstract:
A method of phosphate ester hydrolysis including incubating a solution of an aqueous phosphate ester with a texaphyrin metal complex. The metal is a metal cation having catalytic activity for ester bond hydrolysis in aqueous solution, in particular, a lanthanide metal cation, preferably Eu(III) or Dy(III). A preferred substrate is RNA and a preferred texaphyrin is a derivatized texaphyrin having binding specificity, in particular, a texaphyrin covalently coupled to a site-directed molecule, preferably an oligonucleotide.
