Potholing of the hydrophobic heme oxygenase-1 western region for the search of potent and selective imidazole-based inhibitors
摘要:
Here we report the design, synthesis, and molecular modeling of new potent and selective imidazolebased HO-1 inhibitors in which the imidazole nucleus and the hydrophobic groups are linked by a phenylethanolic spacer. Most of the tested compounds showed a good inhibitor activity with IC50 values in the low micromolar range, with two of them (lb and 1j) exhibiting also high selectivity toward HO-2. These results were obtained by the idea of potholing the entire volume of the principal hydrophobic western region with an appropriate ligand volume. Molecular modeling studies showed that these molecules bind to the HO-1 in the consolidated fashion where the imidazolyl moiety coordinates the heme iron while the aromatic groups are stabilized by hydrophobic interaction in the western region of the binding pocket. Finally, the synthesized compounds were analyzed for in silico ADME-Tox properties to establish oral drug-like behavior and showed satisfactory results. (C) 2018 Elsevier Masson SAS.

D (I),
compositions comprising an effective amount of said compounds either alone or in combination with other chemotherapeutic agents, and methods useful for treating or preventing cancer and for inhibiting tumour tissue growth. These compounds attenuate the oxidative damage associated with increased heme-oxygenase activity and can reduce cell proliferation in transformed cells. In addition, the described compounds and compositions are useful as neuroprotectants and for treating or preventing neurodegenerative disorders and other diseases of the central nervous system.

[EN] Disclosed are compounds of the general formula (1): compositions comprising an effective amount of said compounds either alone or in combination with other chemotherapeutic agents, and methods useful for treating or preventing cancer and for inhibiting tumour tissue growth. These compounds attenuate the oxidative damage associated with increased heme-oxygenase activity and can reduce cell proliferation in transformed cells.

[FR] L'invention porte sur des composés représentés par la formule générale (1), sur des compositions comprenant une quantité efficace desdits composés soit individuellement soit en combinaison avec d'autres agents chimiothérapeutiques, et sur des procédés utiles pour traiter ou prévenir le cancer et pour inhiber une croissance de tissu tumoral. Ces composés atténuent le dommage oxydant associé à une activité accrue de l'hème-oxygénase et permettent de réduire une prolifération cellulaire dans les cellules transformées. De plus, les composés et compositions décrits sont utiles en tant que neuroprotecteurs ainsi que pour traiter ou prévenir des troubles neurodégénératifs et autres maladies du système nerveux central.
