Strictosamide and mitraphylline inhibit cancer cell motility by suppressing epithelial-mesenchymal transition via integrin α4-mediated signaling.

Epithelial-mesenchymal transition (EMT) is a critical process in cancer cell motility and metastasis. Monoterpene indole alkaloids (MIAs) have been widely investigated for biological activities, but rarely been explored for cell motility inhibition. This study aimed to discover natural products, especially focusing on MIAs, that inhibit EMT in cancer cells, based on our screening using multiple plant extracts.

Essential Oils from Vietnamese Asteraceae for Environmentally Friendly Control of Mosquitoes.

Mosquitoes, in addition to being a biting nuisance, are vectors of several pathogenic viruses and parasites. As a continuation of our work identifying abundant and/or invasive plant species in Vietnam for use as ecologically friendly pesticidal agents, we obtained the essential oils of , , , , and ; analyzed the essential oils using gas chromatographic techniques; and screened the essential oils for mosquito larvicidal activity against and . The most active larvicidal essential oils were , which was rich in thymohydroquinone dimethyl ether (29.
