摘要:
Disclosed herein are materials and methods for sensitizing multidrug resistant cancer cells that express ABCG2 and related proteins members of a family of ATP-binding transporter superfamily that mediate drug efflux found in some types of multidrug resistant caner cells. A series of compounds, including (N-(4-chlorophenyl)-2-[(6-{[4,6-di(4-morpholinyl)-1,3,5-tri-azin-2-yl]amino}-1,3-benzothiazol-2-yl)sulfanyl]acetamide), specifically inhibits ABCG2 and can be used to boost the bio-avail-ability of one or more effective cancer killing drugs, making it possible to use certain widely used chemotherapeutic reagent to treat multidrug resistance cancers. Using these compounds in combination with chemotherapeutic drugs that are substrates for ABCG2 and related proteins may also find utility in treating cancer cells that are not currently identified as multi-drug resistant Additionally, these compounds appear to accelerate the intercellular degradation of ABCG2 and related proteins. They are not toxic to animals at levels at which they effect the activity of ABCG2 expressed in multi-drug resistant cancer lines.
摘要:
The present invention provides STAT3 inhibitors which preferentially suppress proliferation of cancer over non-cancer cells and inhibit migration and invasion of malignant cells. The inhibitors of the present invention selectively inhibit STAT3 binding to DNA without affecting the activation and dimerization of STAT3. Furthermore, the inhibitors of the present invention inhibit expression of STAT3 downstream target genes and STAT3 binding to chromatin in situ.
摘要:
Methods for treating various cancers by administering one or more compounds that target the dimeric protein survivin are disclosed. Pharmaceutical compositions containing such compounds are also disclosed, along with general methods of identifying anti-cancer compounds that target oncogenic dimeric proteins. Exemplary compounds that can be used in the disclosed methods of treatment and pharmaceutical compositions have the chemical structure.
