Inhibition of melanin production by anthracenone dimer glycosides isolated from Cassia auriculata seeds
TLDR
The methanol extract of Cassia auriculata seeds was found to inhibit melanogenesis in B16 melanoma 4A5 cells under conditions of theophylline stimulation, suggesting that the inhibition of these factors is part of the mechanism of action underlying melanogenesis inhibition.
Antimicrobial activity of carbazole alkaloids from Murraya koenigii (L) Spreng leave
TLDR
Cytotoxic activity in fresh sheep erythrocytes revealed that mohanimbine does not possess cellular toxicity and koenimbine could not produce either antibacterial or antifungal activities.
Chemical structures of constituents from the whole plant of Bacopa monniera
TLDR
In the present study, bacomosaponins A and B with acyl groups were obtained from the whole plant of B. monniera and significantly inhibited the aggregation of 42-mer amyloid β-protein.
Structures of Aromatic Glycosides from the Seeds of Cassia auriculata.
TLDR
Four new constituents of cassiaglycoside were isolated from the seeds of Cassia auriculata and the chemical structures were characterized on the basis of chemical and physicochemical evidence.
A Review of the Anti-Cancer Potential of Murraya koenigii (Curry Tree) and Its Active Constituents
TLDR
The ameliorating effects of MK and its phytoconstituents against various cancers warrant its multi-institutional clinical trials as soon as possible, and the prospects of relatively cheaper cancer drugs could be brighter, particularly for the socio-economically feebler cancer patients of the world.
Chemical Structures of Phenylbutanoids From Rhizomes of Zingiber cassumunar
Zingiber cassumunar is widely distributed in Asia, and its rhizomes are used for asthma treatment in traditional medicine and as a spice. Five new phenylbutanoids, cassumunols I–M (1-5), were
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.

TLDR
The methanolic extract and its 1-butanol-soluble fraction from the flower buds of Camellia japonica showed inhibitory effects on melanogenesis in theophylline-stimulated B16 melanoma 4A5 cells and structure-activity relationships of the saponins were investigated.
