I want to use KX2-391 (tirbanibulin) to inhibit Src in cultured fibroblasts. Is it known whether treatment with this compound results in decreased or increased phosphorylation of Src? I would like to verify its inhibitory effect by western blotting but I haven't come across any phospho-Src western blot analysis of whole cells treated with KX2-391 in the literature. Any insight would be appreciated!
