Structures of acylated sucroses and an acylated flavonol glycoside and inhibitory effects of constituents on aldose reductase from the flower buds of Prunus mume
TLDR
Several flavonol glycosides including mumeflavonoside A were shown to inhibit aldose reductase, and the chemical structures of the new compounds were elucidated on the basis of chemical and physicochemical evidence.
Structures and Antimutagenic Effects of Onoceranoid-Type Triterpenoids from the Leaves of Lansium domesticum.
A methanol extract of the dried leaves of Lansium domesticum showed antimutagenic effects against 3-amino-1,4-dimethyl-5 H-pyrido[4,3- b]indole (Trp-P-1) and 2-amino-1-methyl-6-phenylimidazo[4,5-
Lignan dicarboxylates and terpenoids from the flower buds of Cananga odorata and their inhibitory effects on melanogenesis.
TLDR
These isolated terpenoid derivatives may be promising therapeutic agents for the treatment of several skin disorders after showing an inhibitory effect on melanogenesis in theophylline-stimulated murine B16 melanoma 4A5 cells.
Association of airborne particles, protein, and endotoxin with emergency department visits for asthma in Kyoto, Japan
TLDR
High concentrations of coarse particles and endotoxin in both particles were significant factors on emergency department visits for asthma in Kyoto City, Japan, suggesting an increased risk of asthma exacerbation.
Melanogenesis inhibitory and fibroblast proliferation accelerating effects of noroleanane- and oleanane-type triterpene oligoglycosides from the flower buds of Camellia japonica.
TLDR
First scientific investigation of a triterpene that displays an inhibitory effect on melanogenesis, but that also has an enhancing effect on fibroblast proliferation is reported, which could make camellioside B useful for treating skin disorders.
