Synthesis and SAR Studies of Dual AKT/NF-κB Inhibitors Against Melanoma
摘要:
The protein Kinase B alpha (AKT) and nuclear factor kappa‐light‐chain‐enhancer of activated B cells (NF‐κB) pathways are central regulators of cellular signaling events at the basis of tumor development and progression. Both pathways are often up‐regulated in different tumor types including melanoma. We recently reported the identification of compound 1 (BI‐69A11) as inhibitor of the AKT and the NF‐κB pathways. Here, we describe SAR studies that led to novel fluorinated derivatives with increased cellular potency, reflected in efficient inhibition of AKT and IKKs. Selected compounds demonstrated effective toxicity on melanoma, breast, and prostate cell lines. Finally, a representative derivative showed promising efficacy in an in vivo melanoma xenograft model.

The present invention describes an improved method for screening compounds for activity in inhibiting the enzymatic activity of Akt1 protein kinase, also known as Protein Kinase B, an enzyme that is believed to play a key role in the inhibition of apoptosis and thus in the etiology of cancer and other conditions, including neurodegenerative diseases. In general, the method comprises: (1) providing a plurality of compounds suspected of having Akt1 kinase inhibitory activity; (2) modeling the docking of each of the plurality of the compounds with a target binding site derived from the crystal structure of a ternary complex involving Akt1, a nonhydrolyzable ATP analogue, and a peptide substrate derived from a physiological AKT substrate such that the protein active site is defined including those residues within a defined distance from the nonhydrolyzable ATP analogue; (3) ranking the docked compounds by goodness of fit; (4) further selecting compounds from compounds high ranked by goodness of fit in docking by using one or more screening criteria; (5) optionally, visually analyzing structures of compounds selected in step (4) to remove any compounds with improbable docking geometry; and (6) experimentally testing the selected compounds from step (4) or step (5), if step (5) is performed, to determine their inhibitory activity against Akt1 in order to select compounds with Akt1 inhibitory activity. The invention also encompasses pharmaceutical compositions including compounds whose inhibitory activity against Akt1 is discovered by the screening method, as well as methods of use of the pharmaceutical compositions to treat cancer and other conditions.
