Dihydroartemisinin (DHA), an antimalarial drug, has previously unrecognized anticancer activity, and is in clinical trials as a new anticancer agent for skin, lung, colon and breast cancer treatment. However, the anticancer mechanism is not well understood. Here, we show that DHA inhibited
Dihydroartemisinin (DHA), one of the main metabolites of artemisinin and its derivatives, presents anti-cancer potential in vitro and in vivo. To explore the mechanisms of resistance toward DHA, a DHA-resistant cell line, HeLa/DHA, was established with a resistance factor of 7.26 in vitro. Upon DHA
BACKGROUND
Dihydroartemisinin (DHA), a semi-synthetic derivative of artemisinin isolated from the traditional Chinese herb Artemisia annua, is an effective novel antimalarial drug. Recent studies suggest that it also has anticancer effect.
OBJECTIVE
The present study was designed to investigate the
The clinical application of dihydroartemisinin (DHA) has been hampered due to its poor water-solubility. To overcome this hurdle, we devised a novel polymer-drug conjugate, multiarm polyethylene glycol-dihydroartemisinin (PEG-DHA), made by linking DHA with multiarm polyethylene glycol. Herein, we
BACKGROUND
Dihydroartemisinin (DHA) exhibits potent anti-malarial and anti-cancer activities. This study aimed to investigate the anti-proliferative effects of a combination of DHA and doxorubicin (DOX) on human breast cancer cells.
METHODS
MTT assay and the combination index (CI) were used to show
Dihydroartemisinin (DHA) has recently shown antitumor activity in various cancer cells. The small GTPase Rac1 regulates many cellular processes, including cytoskeletal reorganization, cell migration, proliferation, and survival. In addition, Rac1 plays a major role in activating NFκB-mediated
OBJECTIVE
Prostate cancer (PCa) is one of the most common cancers in men in the world. Advanced PCa, especially castration-resistant PCa (CRPC), is difficult to cure. There is an urgent need to develop novel agents for CPRC. Dihydroartemisinin (DHA) is a semisynthetic derivative of artemisinin and
The natural extract artemisinin and its derivatives have good anticancer activity. The present study aimed to investigate the in vitro inhibitory effects of combined dihydroartemisinin (DHA) and doxorubicin (DOX) treatment on a variety of tumor cell lines (HeLa, OVCAR-3, MCF-7, PC-3 and A549), as
OBJECTIVE
To investigate the anti-tumor activity of combined gemcitabine with dihydroartemisinin, and the mechanism of the anti-tumor effect of gemcitabine enhanced by dihydroartemisinin on pancreatic cancer.
METHODS
For cultured cells, cell growth was determined by the MTT assay and apoptosis was
Rapid cell death, as evidenced by a decrease in cell counts, was observed when molt-4-lymphoblastoid cells, a human leukemia cell line, were exposed to holotransferrin (12 microM) and dihydroartemisinin (1-200 microM). Incubation with either compound alone was significantly less effective.
Dihydroartemisinin (DHA) is a promising anti-cancer compound capable of inhibiting proliferation and inducing apoptosis of various cancer cells, including colorectal cancer. However, the molecular mechanisms have not been well understood. This study aimed to explore the underlying mechanism of
In traditional Chinese medicine, dihydroartemisinin (DHA) is the focus of extensive attention because of its unique activity with Fe2+ to produce reactive oxygen species (ROS) and promote apoptosis. In this work, we designed a newfangled ink@hydrogel containing FeCl3,
Artemisinin is an anti-malarial drug with poor water solubility and oral absorption; so a variety of derivatives based on the parent nucleus have been developed. Compared with artemisinin, dihydroartemisinin (DHA) has a stronger anti-malaria activity, and has the advantages of high metabolic rate
Dihydroartemisinin (DHA), a semi-synthetic derivative of the herb artemisinin, has shown commendable bioactivity. In this paper, a novel dihydroartemisinin-organogermanium (DHA-Ge) compound was synthesized, characterized and its potential anti-tumor activity was evaluated by various methods. MTT
Artemisinin and its derivatives (ARTs) are effective antimalarial drugs and also possess profound anticancer activity. However, the mechanism accounted for its distinctive activity in tumor cells remains unelucidated. We computed Pair wise Pearson correlation coefficients to identify genes that show
