Abstract: The present invention relates to the use of a novel class of cancer stem cell pathway (CSCP) inhibitors; to methods of using such compounds to treat refractory, recurrent, or metastatic cancers; to methods of selective killing cancer cells by using such compounds with specific administration regimen; to methods of targeting cancer stem cells by inhibiting Stat3 pathway; to methods of using novel compounds in the treatment of conditions or disorders in a mammal related to aberrant Stat3 pathway activity; and to processes for preparing such compounds and intermediates thereof, and to the pharmaceutical composition of relevant compounds, and to the specific methods of administration of these compounds.

Abstract: The present invention relates to a novel naphtho class of compounds as Stat3 pathway inhibitors and as cancer stem cell inhibitors; to methods of using such compounds to treat cancer; to methods of using such compounds to treat disorders in a mammal related to aberrent Stat3 pathway activity; to pharmaceutical compositions containing such compounds.

Abstract: The present invention provides double-stranded RNA molecules that are asymmetrical in strand length. The RNA molecule of the invention, the asymmetric RNA duplex, has one or two overhangs at the end. In one aspect, these novel RNA duplex molecules serve as effective mimetics of miRNA. In another aspect, they are designed to function as effective inhibitors of miRNA. Accordingly, the RNA molecules of the present invention can be used to modulate miRNA pathway activities, with tremendous implications for research, drug discovery and development, and treatment of human diseases.
