SAR and evaluation of novel 5H-benzo[c][1,8]naphthyridin-6-one analogs as Aurora kinase inhibitors
摘要:
Several potent Aurora kinase inhibitors derived from 5H-benzo[c][1,8]naphthyridin-6-one scaffold were identified. A crystal structure of Aurora kinase A in complex with an initial hit revealed a binding mode of the inhibitor within the ATP binding site and provided insight for structure-guided compound optimization. Subsequent SAR campaign provided a potent and selective pan Aurora inhibitor, which demonstrated potent target modulation and antiproliferative effects in the pancreatic cell line, MIAPaCa-2. Furthermore, this compound inhibited phosphorylation of histone H3 (pHH3) in mouse bone morrow upon oral administration, which is consistent with inhibition of Aurora kinase B activity.

A simple, mild and highly efficient condition for amide synthesis from acylchlorides has been developed to minimize hydrolysis, racemization and other side reactions. This method should expand capabilities in the peptide coupling area.
