Modulating Molecular Functions of p53 with Small Molecules

INTERACTION OF PROTEINS WITH SMALL MOLECULES

Modulating splicing with small molecular inhibitors of the spliceosome.

Small molecule inhibitors that target components of the spliceosome have great potential as tools to probe splicing mechanism and dissect splicing regulatory networks in cells. These compounds also hold promise as drug leads for diseases in which splicing regulation plays a critical role, including many cancers. Because the spliceosome is a complicated and dynamic macromolecular machine compris...

Mutant p53 exerts oncogenic functions by modulating cancer cell metabolism

The metabolic function of p53 is important for its oncosuppressive function. Mutant p53 (mutp53) with gain of oncogenic function can regulate cell metabolism. Our recent study revealed a novel transcription-independent mechanism for a gain-of-function mutp53 that directly inhibits activation of adenosine monophosphate-activated protein kinase (AMPK) to promote cancer cell metabolism.

Small P-gp modulating molecules: SAR studies on tetrahydroisoquinoline derivatives.

The development of small molecules as P-gp modulating agents and SAR studies on these ligands represented the aim of the present work. A series of 6,7-dimethoxytetrahydroisoquinoline derivatives was prepared and their ability to inhibit P-gp activity has been evaluated. The basic nucleus of these compounds, common to the best P-gp inhibitors such as Tariquidar and Elacridar, has been functional...
