Abstract: Mercaptoamide compounds, represented by Formulas (IA), (IB), (IIA), and (IIB): or a pharmaceutically acceptable salt thereof, inhibit histone deacetylase enzyme and are useful for the treatment and/or prevention of various infections, cancerous diseases, and conditions.

Abstract: The invention provides complexes of at least two polypeptides, and methods of using the same. Purified complexes of two polypeptides are provided, including chimeric complexes, and chimeric polypeptides and complexes thereof are also provided, as are nucleic acids encoding chimeric polypeptides and vectors and cells containing the same. Also provided are methods of identifying agents that disrupt polypeptide complexes, methods of identifying complex or polypeptide in a sample, and for removing the same, methods of determining altered expression of a polypeptide in a subject, and methods of treating/preventing disorders involving altered levels of complex or polypeptide.
