Résumé
Aquilaria crassna, commonly known as agarwood, is a plant used in traditional Asian medicine and perfumes, demonstrating neuroprotective, antidiabetic, and antimicrobial properties in laboratory and animal studies [PMID:28505589, 39203863, 27534110, 23962360].
Contexte
Aquilaria crassna is a tropical tree that produces agarwood, a resinous heartwood used for medicines, incenses, and perfumes [PMID:28505589, 20056366].
Usages traditionnels
In traditional Asian medicine, it has been used to treat vomiting, rheumatism, asthma, cough [PMID:27450078], and infectious diseases such as diarrhea and skin diseases [PMID:23962360]. In Thailand, the leaves are used for various disorders [PMID:23326086] and are consumed as tea to promote physiological balance and cardiovascular function [PMID:31453117].
Composés actifs
Active compounds include sesquiterpenes (e.g., $\alpha$-guaiene, $\alpha$-humulene, $\delta$-guaiene, $\beta$-caryophyllene, agarospirol) [PMID:21472475, 26132906, 38419767], chromones (including 2-(2-phenylethyl)chromone dimers and derivatives) [PMID:35217119, 28984476, 28300702], polyphenols (mangiferin, epigallocatechin gallate, epicatechin gallate, iriflophenone 3-C-$\beta$-glucoside) [PMID:31453117, 25153858, 33113908], and cucurbitacin triterpenoids (e.g., cucurbitacin E, neocucurbitacin A) [PMID:38024711].
Mécanisme d'action
Leaf extracts may exert neuroprotective effects by normalizing cell cycle progression via the AhR/CYP1A1/cyclin D1 pathway [PMID:37764767] and increasing protein levels of GAP43 and neuroglobin [PMID:39203863]. Some compounds act as STAT3 inhibitors [PMID:38024711] or inhibit $\alpha$-glucosidase through uncompetitive inhibition [PMID:27534110].
Preuves cliniques
Preuve DNeurotoxicity (B[a]P-induced)
Ethanolic leaf extract (ACEE) exerted neuroprotective effects against Benzo[a]pyrene-induced toxicity in human SH-SY5Y cells [PMID:39203863].
Preuve DType-2 Diabetes
Water extract of leaves showed hypoglycemic and antioxidant activities in STZ-NA-induced diabetic mice [PMID:27534110].
Preuve DPain and Fever
Aqueous leaf extract (400-800 mg/kg) significantly reduced rectal temperature in rats and decreased heat sensitivity in mice [PMID:23326086].
Preuve DVascular Function
Aqueous leaf extract and mangiferin acted as vasodilators in rat mesenteric arteries and aortae [PMID:31453117].
Preuve DBacterial Infection
Leaf extract demonstrated antibacterial activity against Staphylococcus epidermidis by disrupting the cell wall [PMID:23962360].
Sécurité et effets indésirables
In acute toxicity studies in Swiss female mice, a single oral dose of 2000 mg/kg/day of essential oil extract was evaluated [PMID:27450078]. Aqueous leaf extract (0.1-1000 $\mu$g/ml) showed no cytotoxicity on rat vascular smooth muscle cells [PMID:31453117].
Synthèse des preuves
The current evidence is based primarily on in vitro cell lines, animal models (rodents, C. elegans), and phytochemical isolation. There are no human clinical trials provided.
