Mitigation of cardiovascular toxicity in a series of CSF-1R inhibitors, and the identification of AZD7507
摘要:
The potent and selective 3-amido-4-anilinoquinoline CSF-1R inhibitor AZ683 suffered from cardiovascular liabilities, which were linked to the off-target activities of the compound and ion channel activity in particular. Less basic and less lipophilic examples from both the quinoline and cinnoline series demonstrated cleaner secondary pharmacology profiles. Cinnoline 31 retained the required potency and oral PK profile, and was progressed through the safety screening cascade to be nominated into development as AZD7507. (C) 2013 Elsevier Ltd.

Provided herein are systems and methods for selecting compounds that have reduced risk of cardiotoxicity or which are not likely to be cardiotoxic. As an example, a system and method can include a computational dynamic model combined with a high throughput screening in silico that mimics an important ion channels associated with cardiotoxicity, namely the human cardiac sodium ion (hNa
v
1.5) channel). In certain embodiments, steered molecular dynamics simulations are used to identify key residues of the channel's permeation pathways that are then used in the high throughput screening. Also provided herein are systems and methods for redesigning compounds that are predicted to be cardiotoxic based on the model and the high throughput screening.
