Abstract: The present invention relates to a homology model for PLK, and the use thereof in assays for the identification of small molecule PLK modulators. The invention further relates to PLK modulators identified by said assays, and their use in the treatment of PLK-related disorders such as proliferative disorders.

Abstract: This invention relates to a method for analyzing a sample comprising: immobilising a polypeptide to a physical support; contacting the immobilised polypeptide with a test sample which may contain an agent capable of modifying the immobilised polypeptide; contacting the immobilised polypeptide with a binding partner polypeptide, wherein the binding of this partner polypeptide to the immobilised polypeptide is at least partly dependent on the modification state of the immobilised polypeptide; and measuring the association of the binding partner polypeptide to the immobilised polypeptide.

Abstract: The present invention relates to the use of a compound of formula I, or a pharmaceutically acceptable salt thereof, wherein R1, R2, R3, and R4 are each independently H, NO2, CF3, SCF3, CN, halo, OH, OR6, NH2, NHR6, NR6R7, N+R6R7R8, COOH, COOR6, CONH2, CONHR6, CONR6R7, COH, COR6, SR6, SOR6, SO2R6, SO2OH, SO2OR6, SO2NH2, SO2NHR6, SO2NR6R7, alkyl, cycloalkyl, cycloheteroalkyl, aryl, or heteroaryl, with the proviso that at least one of R1, R2, R3, and R4 is other than H; or R1 and R2, R2 and R3, or R3 and R4, may together form part of a fused or unfused saturated or unsaturated ring system, optionally containing up to two heteroatoms selected from N, O, and S; R5 is OH, OR9, CN, CONH2, CONHNH2, CONHOH, CONHR9, CONR9R10, NH2, NHR9, or NR9R10; each R6, R7 and R8 is independently hydrocarbyl, or two of R6, R7 and R8 together form part of a saturated or unsaturated ring system, optionally containing up to two heteroatoms selected from N, O, and S; each R9 and R10 is independently hydrocarbyl, or R9 and R10 to
