Biflavonoid Methylchamaejasmin and Khaya grandifoliola Extract Inhibit NLRP3 Inflammasome in THP-1 Cell Model of Neuroinflammation

Molecular Neurobiology
Neuroinflammation is a common hallmark of Alzheimer's disease (AD), with NLRP3 inflammasome proven to be activated in microglia of AD patients' brains. In this study, a newly isolated biflavonoid (7,7'-di-O-methylchamaejasmin/M8) and a crude extract of the plant Khaya grandifoliola (KG) were investigated for their inhibitory effect on inflammasome ...

Chemical constituents from the seeds of Khaya grandifoliola C.DC; their chemophenetic significance and antibacterial activities

Biochemical Systematics and Ecology
Chemical exploration of the CH2Cl2/MeOH extract of the seeds of Khaya grandifoliola C.DC led to the isolation of one previously unreported limonoid (7), together with 19 known compounds. The structures of all the isolated compounds were established by interpretation of their spectroscopic and spectrometric data, including 1D and 2D NMR and HRESIMS ...

Unveiling an important interaction in forestry: Ectomyelois muriscis and Khaya grandifoliola cankers and tree growth

Journal of Forestry Research, 2020
African mahogany, Khaya grandifoliola C. DC., is the most planted mahogany species in Brazil, and became the choice species when plantations of Brazilian mahogany, Swietenia macrophyla King became unsustainable due to their susceptibility to the shoot borer Hypsipyla grandella Zeller. This study evaluated plantation growth and the occurrence of cankers

Limonoids from the stem bark of Khaya grandifoliola

Phytochemistry, 2008
Three limonoids, deacetylkhayanolide E (1), 6S-hydroxykhayalactone (2), and grandifolide A (3), along with three known ones, were isolated from stem bark of the Nigerian medicinal plant Khaya grandifoliola. Their structures were characterized on the basis of the application of spectroscopic methods.

Properties of Khaya grandifoliola gum

Journal of the Science of Food and Agriculture, 1978
AbstractThe gum exudate of Khaya grandifoliola has only limited solubility in water. Analysis of the gum showed that approximately 50% was in the free acid form and the remainder was largely the calcium salt. The gum dissolves in sodium carbonate solution with removal of calcium ions.

Khayalactone, a novel limonoid from Khaya grandifoliola

Tetrahedron Letters, 1998
Abstract The isolation and structure elucidation by spectroscopic methods of khayalactone (1) from extracts of Khaya grandifoliola is described. Khayalactone is a novel hexacyclic A,B,D-seco limonoid with a highly oxidised carbon framework.
