Novel Developments on Artemisinin and Its Derivatives for Cancer Therapy

2009

The lack of effective long-term anticancer therapy highlights the necessity to identify new potent anticancer compounds. Many biocompounds of naturally occurring medicinal plants have pharmacological activities and, thus, represent a source of molecules that may have anti-proliferative effects on a variety of cancers. During the past 10 years, we have systematically analyzed medicinal plants used in traditional Chinese medicine and focused our interest on Artemisia annua (sweet wormwood herb). The active principle of sweet wormwood herb is Artemisinin, a sesquiterpene, which exerts not only anti-malarial activity but also profound cytotoxicity against tumour cells. The anti-tumour mechanism…

Synthesis and biological evaluation of antimalarial and antileukemic activity of new C-10 modified artemisinin derivatives

2021

Abstract Several non-acetal artemisinin derivatives were synthesized and their antimalarial activity against chloroquine-resistant parasites as well as their antileukemic activity were investigated. The azide 10 was proved to have slightly better activity than the current antimalarial drugs such as artesunate and chloroquine. In addition, the azide 10 and the aldehyde 7 were found to be effective in decreasing cell proliferation in leukemia cells.

Cytotoxicity of natural products and derivatives toward MCF-7 cell monolayers and cancer stem-like mammospheres

2015

Abstract Although cancer stem-like cells (CSCs) are rare, they can enter a non-proliferative or dormant state and resist therapy. Furthermore, quiescent CSCs are responsible for metastases that can appear after curative surgical treatment of a primary tumor. Because of drug resistance of CSCs, the development of novel therapies is urgently required that specifically target CSCs. Purpose The aim of the present study was to investigate the potential of a panel of natural products and derivatives to inhibit CSC-enriched mammospheres of MCF-7 breast cancer cells. Methods CD44high/CD24low cells were identified by flow cytometry and maintained as mammospheres. As a control, we used two clinically…
