摘要
Artemisinin-estrogen hybrids were for the first time both synthesized and investigated for their biological activity against malaria parasites ( 3D7), human cytomegalovirus (HCMV), and a panel of human malignant cells of gynecological origin containing breast (MCF7, MDA-MB-231, MDA-MB-361, T47D) and cervical tumor cell lines (HeLa, SiHa, C33A). In terms of antimalarial efficacy, hybrid (EC = 3.8 nM) was about two times more active than its parent compound artesunic acid () (EC = 8.9 nM) as well as the standard drug chloroquine (EC = 9.8 nM) and was, therefore, comparable to the clinically used dihydroartemisinin () (EC = 2.4 nM). Furthermore, hybrids - showed a strong antiviral effect with EC values in the submicromolar range (0.22-0.38 μM) and thus possess profoundly stronger anti-HCMV activity (approximately factor 25) than the parent compound artesunic acid () (EC = 5.41 μM). These compounds also exerted a higher anti-HCMV efficacy than ganciclovir used as the standard of current antiviral treatment. In addition, hybrids - elicited substantially more pronounced growth inhibiting action on all cancer cell lines than their parent compounds and the reference drug cisplatin. The most potent agent, hybrid , exhibited submicromolar EC values (0.15-0.93 μM) against breast cancer and C33A cell lines.
