Methods of using the compositions to treat cancer and other diseases are also provided.

Abstract: Disclosed are methods of enhancing the chemotherapeutic treatment of tumor cells, reducing resistance of a cancer cell to a chemotherapeutic agent, a method of inhibiting ABCG2 or MRP1 in a mammal afflicted with cancer, and a method of increasing the bioavailability of an ABCG2 substrate drug in a mammal. The methods comprise administering peliomycin and other compounds described herein.

Abstract: Disclosed are methods of enhancing the chemotherapeutic treatment of tumor cells, reducing resistance of a cancer cell to a chemotherapeutic agent, a method of inhibiting ABCG2, Pgp, or MRP1 in a mammal afflicted with cancer, and a method of increasing the bioavailability of an ABCG2 substrate drug in a mammal. The methods comprise administering effective amounts of certain compounds to the mammal, for example, a compound of the formula (I): wherein R1, R2, R3, X1, X2, X3, a, and b are as described herein. Uses of these compounds in the preparation of a medicament are also disclosed. Also disclosed are compounds of formula (II), pharmaceutical compositions comprising such compounds and uses thereof.

Abstract: The present invention relates to deacetylase inhibitor (e.g., histone deacetylase inhibitor) therapies and demonstrates that individuals with low electrolyte levels may have increased susceptibility to certain unwanted side effects such as cardiac side effects. In some embodiments, the invention provides methods of administering DAC or DAC inhibitor therapy that includes electrolyte supplementation.
