Patent ID: 7826982

Claim:
A method for selecting chemical entities with an increased probability of associating with: a) a molecule or molecular complex comprising a binding pocket defined by the structure coordinates of all atoms of Rac-1 GTPase amino acids Trp-56, Lys-5, Val-7, Ser-71, Val-36, Tyr-64, Arg-68, and Pro-73, as provided in Table 1 or Table 2; or b) a homolog of said molecule or molecular complex, wherein said homolog comprises a binding pocket that has all atoms of Rac-1 GTPase amino acids Trp-56, Lys-5, Val-7, Ser-71, Val-36, Tyr-64, Arg-68, and Pro-73, where the backbone atom positions in said homolog have a root mean square deviation from the backbone atom positions of said amino acids in Table 1 or Table 2 of not more than about 1.5 Angstrom, the method comprising: (i) generating, on a computer, a three dimensional structure of the binding pocket of the molecule or molecular complex or the binding pocket of said homolog thereof; (ii) performing a fitting operation between a three dimensional structure of a chemical entity and the three dimensional structure of the binding pocket of the molecule or molecular complex or the binding pocket of said homolog thereof; (iii) analyzing the results of said fitting operation to quantify the association between the chemical entity and the binding pocket of the molecule or molecular complex or the binding pocket of said homolog thereof, wherein said analyzed results are indicative of the potential of the chemical entity to associate with the molecule or molecular complex or said homolog thereof; and (iv) selecting for those chemical entities with an increased probability of associating with said molecule or molecular complex or said homolog thereof.
