The method may comprise modelling a three dimensional structure of a plurality of molecules in a computer, comparing with the three dimensional structure of the compounds with that of a reference structure such as at least part of a protein kinase catalytic domain of PDK1, and selecting the compound based on a predicted interacting ability of the molecules to the protein kinase catalytic domain. Also a method for selecting a compound for modulating the activity of hydrophobic pocket containing protein kinase is provided. In this method, the reference structures may be one or more of a phosphate binding pocket of PDK1, a hydrophobic pocket of PDK1, and αC helix or region interacting therewith of PDK1.

    摘要: A method for identifying a compound for use in modulating, for example promoting, the activation or phosphorylation of AMPK (AMP-activated protein kinase) or AMPK subfamily member in a cell, the method comprising the steps of (1) determining whether a test compound modulates, for example promotes, the protein kinase activity of LKB1 and (2) selecting a compound which modulates, for example promotes, the protein kinase activity of LKB1. The protein kinase activity may be tested using AMPK or an AMPK subfamily member, or a peptide encompassing the T-loop region of AMPK or an AMPK subfamily member. The LKB1 may be in a preparation or complex with STRAD and/or M025, which has much greater kinase activity than LKB1 in the absence of these accessory proteins. The LKB1, STRAD or M025 may be recombinant. The AMPK subfamily member may be AMPKα1, AMPKα2, NUAK1, NUAK2, BRSK1, BRSK2, SIK, QIK, QSK, MARK1, MARK2, MARK3, MARK4 or MELK.
