Abstract:
The structure-activity relationships of new Aurora A/B kinase inhibitors derived from the previously identified kinase inhibitor 12 are described. Introduction of acetic acid amides onto the pyrazole of compound 12 was postulated to influence Aurora A/B selectivity and improve the profile against off-target kinases. The SAR of the acetic acid amides was explored and the effect of substitution on enzyme inhibition as well as mechanism-based cell activity was studied. Additionally, several of the more potent inhibitors were screened for their off-target kinase selectivity.

Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
