uncaria rhynchophylla/항진균제

Isorhynchophylline (IRN) and rhynchophylline (RN), a pair of stereoisomers, are tetracyclic oxindole alkaloids isolated from Uncaria rhynchophylla, a commonly used Chinese medicinal herb. These two compounds have drawn extensive attention due to their potent neuroprotective effects with

To investigate the effects of Listeriolysin O (LLO) on morphology, nitric oxide (NO) and endothelin-1 (ET-1) release by rat intestinal microvascular endothelial cells (RIMECs). We aimed to elucidate a preliminary therapeutic mechanism of action of rhynchophylline and isorhynchophylline (active

Traditional Chinese medicine (TCM) has a long history in stroke therapy and its therapeutic efficacy has been confirmed by clinical studies. The molecular basis of the neuroprotective effects is unknown. We wondered whether or not the neuroprotective effect of TCMs might be due to their

Spiro-oxindole scaffolds have been studied due to their promising therapeutic potential. In the Amazon rainforest there are two important Uncaria species known as "cat's claw", which biosynthesize spirocyclic oxindole alkaloids; Uncaria tomentosa (Willd. ex Schult.) DC. and Uncaria

We identified a neuroprotective single fraction among 62 ones of hexane extract from Uncaria sinensis (JGH43IA) and investigated its effects and mechanisms in primary cortical neurons. Pretreatment with JGH43IA showed a significantly increase cell viability in a dose-dependent manner with a decrease

We identified a novel neuroprotective compound, 1-methoxyoctadecan-1-ol, from Uncaria sinensis (Oliv.) Havil and investigated its effects and mechanisms in primary cortical neurons and in a photothrombotic ischemic model. In primary rat cortical neurons against glutamate-induced neurotoxicity,

BACKGROUND This study was designed to determine if a natural mineral supplement, sierrasil, alone and in combination with a cat's claw extract (Uncaria guianensis), vincaria, has therapeutic potential in mild to moderate osteoarthritis of the knee. METHODS Patients (n = 107) with mild to moderate

Uncaria gambir (local name: gambir) is a plant native to Sumatera, Malaya and Borneo. This plant is potential as local wisdom for therapeutics. In Sumatera, gambir was used as a traditional treatment for fever, diarrhoea, diabetics and wound

Chronic microglial activation endangers neuronal survival through the release of various pro-inflammatory and neurotoxic factors. As such, negative regulators of microglial activation have been considered as potential therapeutic candidates to reduce the risk of neurodegeneration associated with

BACKGROUND Osteoarthritis (OA) is a chronic debilitating degenerative joint disease characterized by cartilage degradation and synovial inflammation exhibited by clinical symptoms such as joint swelling, synovitis, and inflammatory pain. Present day pain relief therapeutics heavily relies on the use

Uncaria sinensis (US) has long been used as a traditional Korean medicine to treat cardiovascular and central nervous system diseases, including hypertension and cerebral ischemia. Several recent studies have indicated that US has neuroprotective and cerebrovascular protective effects in ischemic

Accumulating evidence suggests that natural medicines have notable curative effects on neurological conditions, such as migraine, that are mediated by regulating the gut microbial flora. A natural medicine pair used in traditional Chinese medicine, Gastrodia elata Blume and Uncaria
