    Impact of Artemisinin-based Combination Therapy on falciparum malaria in urban Kolkata: a clinic based report.[Pubmed: 25720645]
    In India, Artemisinin-based combination therapy (ACT; specifically artesunate + sulfadoxine-pyrimethamine) has been implemented for uncomplicated falciparum malaria since 2010. But for vivax malaria drug policy remained unchanged i.e., chloroqine and primaquine.
    METHODS AND RESULTS:
    We observed the impact of this intervention in urban Kolkata by analyzing data from the Malaria Clinic from 2001 to 2013. In Kolkata, we observed that Plasmodium vivax was perennial, whereas P. falciparum infection was seasonal. Before ACT implementation, the proportion of P. falciparum was as high as 50% and it steadily decreased during 4 successive years post intervention. No change was observed in the number of P. vivax cases.
    CONCLUSIONS:
    ACT may be an effective measure in reducing falciparum malaria cases. Artemisinin-derivative combination therapies should be explored in vivax malaria to reduce the overall burden of malaria.

    Antimicrobial activity of artemisinin and its precursors.[Reference: WebLink]
    Artemisinic acid and Arteannuin B are biogenetic precursors of Artemisinin, an important antimalarial produced by the herb Artemisia annua. These compounds have been screened for antimicrobial activity against a range of organisms.
    CONCLUSIONS:
    All the three compounds are active against different bacteria and certain fungal species.

    The antimalarial agent artesunate causes sperm DNA damage and hepatic antioxidant defense in mice.[Pubmed: 25726169]
    Artesunate is an Artemisinin derivative effective against multidrug resistant malaria.
    METHODS AND RESULTS:
    We analyzed the effects of artesunate 40 mg/kg b.w. as a single dose (ART1) or 13.3mg/kg b.w. for 3 days at 24h intervals (ART2) on mice spermatozoa at morphological and molecular level, and hepatic antioxidant status following 24h and 35 days following exposures in vivo. Artesunate significantly reduced epididymal sperm count and increased the frequency of sperms with abnormal head morphology following 24h of exposure. Comet assay analysis revealed significant increase in DNA strand breaks in spermatozoa evidenced by about 3-fold increase in comet tail DNA and up to 10-fold increase in Olive tail moment following 35 days of artesunate treatment. The damage index was significantly higher in the treated groups (40.27 ± 6.62 and 37.07 ± 5.35 for ART1 and ART2 respectively) as compared to the control group (16.13 ± 3.21) indicating the genotoxic effect of artesunate. The significant reduction in GSH, SOD and increase in lipid peroxidation indicate involvement of oxidative mechanisms in artesunate induced toxicity in mice.
    CONCLUSIONS:
    The present study suggests that artesunate has the potential to breach the testis-blood barrier and cause toxicity to male germ cells which may have implications in male reproductive toxicity.

Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

    Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

    After receiving: The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

    Artemisinin inhibits tumor necrosis factor-α-induced vascular smooth muscle cell proliferation in vitro and attenuates balloon injury-induced neointima formation in rats.[Pubmed: 25707499]
    The aim of this study was to evaluate the effect of Artemisinin (ART) on rat vascular smooth muscle cell (VSMC) proliferation induced by tumour necrosis factor (TNF)-α, cell cycle arrest, and apoptosis, and its effect on neointima formation after balloon injury of rat carotid artery.
    METHODS AND RESULTS:
    Primary rat VSMC were identified by immunofluorescence assay. The proliferation of VSMC induced by TNF-α was significantly inhibited by ART treatment in a dose-dependent manner. Treatment with 100-μM ART significantly reduced the expression of proliferating cell nuclear antigen. In contrast, the same treatment arrested the cell cycle in G0/G1 phase. Western blot analysis showed that the cell cycle-related proteins cyclin D1, cyclin E, cyclin-dependent kinase 2, and cyclin-dependent kinase 4 were downregulated by ART in TNF-α-stimulated VSMC. For apoptosis induced by ART, cleaved caspase-3/-9 was detected, and the pro-apoptotic protein Bcl-2-associated X protein was upregulated while the anti-apoptotic protein Bcl-2 was downregulated.
    CONCLUSIONS:
    The results suggest that ART can effectively inhibit the proliferation of VSMC induced by TNF-α through the apoptotic induction pathway and cell cycle arrest. Also, balloon injury indicated that ART significantly inhibited neointima formation in the rat carotid arteries.
