Chalconoid
Chalconoids Greek: χαλκός ''khalkós'', "copper", due to its color), also known as ''chalcones'', are natural phenols related to chalcone. They form the central core for a variety of important biological compounds. They show antibacterial, antifungal, antitumor and anti-inflammatory properties. Some chalconoids demonstrated the ability to block voltage-dependent potassium channels. Chalcones are also natural aromatase inhibitors. Chalcones are aromatic ketones with two phenyl rings that are also intermediates in the synthesis of many biological compounds. The closure of hydroxychalcones causes the formation of the flavonoid structure. Flavonoids are substances in the plant secondary metabolism with an array of biological activities. Chalconoids are also intermediates in the Auwers synthesis of flavones. Chemical properties Biosynthesis and metabolism Chalcone synthase is an enzyme responsible for the production of chalconoids in plants. Chalcone isomerase is responsi ...

Kava
Kava or kava kava (''Piper methysticum'': Latin 'pepper' and Latinized Greek 'intoxicating') is a crop of the Pacific Islands. The name ''kava'' is from Tongan and Marquesan, meaning 'bitter'; other names for kava include ''ʻawa'' (Hawaiʻi), ''ʻava'' (Samoa), ''yaqona'' or ''yagona'' (Fiji), ''sakau'' (Pohnpei), ''seka'' (Kosrae), and ''malok'' or ''malogu'' (parts of Vanuatu). Kava is consumed for its sedating effects throughout the Pacific Ocean cultures of Polynesia, including Hawaii and Vanuatu, Melanesia, some parts of Micronesia, such as Pohnpei and Kosrae, and the Philippines. The root of the plant is used to produce a drink with sedative, anesthetic, and euphoriant properties. Its active ingredients are called kavalactones. A systematic review done by the British nonprofit Cochrane concluded it was likely to be more effective than placebo at treating short-term anxiety. Moderate consumption of kava in its traditional form, i.e., as a water-based suspension of kav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flavokavain A
Flavokavain A is a flavokavain found in the kava plant. It induces apoptosis in bladder cancer cells via a Bax protein-dependent and mitochondria-dependent apoptotic pathway. Flavokavains A and B enhance hepatotoxicity of paracetamol, underscoring a potentially serious interaction between paracetamol and kava.

Kavalactone
Kavalactones are a class of lactone compounds found in kava roots and Alpinia zerumbet (Shell ginger). Kavalactones are under research for potential to have various psychotropic effects, including anxiolytic and sedative/ hypnotic activities. Enzyme inhibition Kava extract has been shown in vitro to potentially inhibit a wide range of hepatic enzymes, suggesting a possible potential for interactions with many pharmaceuticals and herbal medications. In human volunteers in vivo inhibition is currently limited to CYP1A2, and CYP2E1 through use of probe drugs to measure inhibition. Research Several preliminary studies are assessing potential effects of kava, including its anxiolytic actions and hepatotoxicity, but the role specifically of kavalactones among many other kava compounds for these effects remains under study. Kavalactone type compounds may help protect against high glucose induced cell damage. Toxicity Several kavalactones (e.g. methysticin and yangonin) affect a gr ...
