Small molecule modulators of protein function

In chemogenomics and drug discovery, the most challenging task is to find small molecule modulators of protein function that specifically modulate the protein function of interest. Combinatorial chemistry has emerged as a powerful tool to address this problem by generation of large compound...

The Challenge to Make Small-Molecule Modulators of Protein Function... 

The ligand binding or catalytic sites are the most relevant parts of a protein domain for the development of small molecules as modulators of protein function. There is evidence that proteins with conserved folds often also have their functional sites on the same topological location. In some cases a remarkable conservatism in functional sites can be observed. This is true for the example described later in this review on similarity of Cdc25A phosphatase, acetylcholinesterase (AChE) and 1 Ifl-hydroxysteroid dehydrogenases (1 l HSD) (Fig. 9). Nevertheless, it should be stressed that the correlation patterns of amino acid sequence, protein fold and protein function remain a matter of debate. Moreover, a vast number of specific functions can be carried out by the limited number of protein domains due to the high amino acid diversity of proteins with similar folds. " ...
