The invention provides specific small molecule compounds that allosterically regulate the activity or modulate protein-protein interactions of AGC protein kinases and the Aurora family of protein kinases, methods for their production, pharmaceutical compositions comprising same, and their use for preparing medicaments for the treatment and prevention of diseases related to abnormal activities of AGC protein kinases or of protein kinases of the Aurora family.

We report herein an unprecedented conjugate addition of enolizable ketones and unprotected mercaptoacetic acid to electron-poor alkenes using graphene oxide as a phase transfer catalyst. The envisaged protocol is versatile and applicable to structurally different Michael acceptors such as α,β-unsaturatedaldehyde/ketone/acid/ester/amide/nitrile, and β-nitroalkene to afford their corresponding adducts

The protein kinase C-related kinase 2 (PRK2)interacting fragment (PIF) pocket of phosphoinositide-dependent kinase-1 (PDK1) was proposed as a novel target site for allosteric modulators. In the present work, We describe the design, synthesis, and structure-activity relationship of a series of 2-(3-oxo-1,3- diphenylprapyl)malonic acids as potent allosteric activators binding, to the PIF pocket: Some congeners displayed AC(50) values for PDK1 activation in the submicromolar range. The potency of the best compounds to stabilize PDK1 in a thermal stability shift assay was in the same order Of magnitude as that of the PIF pocket binding peptide PIFtide, suggesting comparable binding affinities to the pm pocket, The crystal structure of PDK1 in complex with compound 4h revealed that additional ionic interactions are mainly responsible for the increased potency compared to the monocarboxylate analogues. Notably, several compounds displayed high selectivity for PDK1 Employing a prodrug strategy, we were able to corrroborate the novel mechanism of action in cells.
