In vitro and in vivo evaluation of tubulin inhibitors with non-small cell lung cancer pre-clinical models

Indolo[2,3- d ]benzazepines (indololatonduines) are rarely discussed in the literature. In this project, we prepared a series of novel indololatonduine derivatives and their Ru II and Os II complexes and investigated their microtubule-targeting properties in comparison with paclitaxel and colchicine. Compounds were fully characterized by spectroscopic techniques ( 1 H NMR and UV–vis), ESI mass-spectrometry, and X-ray crystallography, and their purity was confirmed by elemental analysis. The stabilities of the compounds in DMSO and water were confirmed by 1 H and 13 C NMR and UV–vis spectroscopy. Novel indololatonduines demonstrated anticancer activity in vitro in a low micromolar concentration range, while their coordination to metal centers resulted in a decrease of cytotoxicity. The preliminary in vivo activity of the Ru II complex was investigated. Fluorescence staining and in vitro tubulin polymerization assays revealed the prepared compounds to have excellent microtubule-destabilizing activities, even more potent than the well-known microtubule-destabilizing agent colchicine.
