Anti-Plasmodium activity of imidazole–dioxolane compounds
摘要:
A series of imidazole-dioxolane compounds, which we hypothesize should bind to heme and thus interfere with heme catabolism in the parasite, were assayed for inhibitory activity in Plasmodium falciparum cultures and the results were compared to those obtained with Chinese hamster ovary (CHO) cells. The majority of the compounds displayed a similar ratio of inhibitory activity in the two culture systems; however, a number of the compounds tested showed promising anti-Plasmodium activity. The mechanism of action of these compounds remains unclear, however their inability to act synergistically with chloroquine suggests that, if they are inhibiting heme detoxification, they do so in a manner that does not complement the action of chloroquine.

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.

[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.
