Central and peripheral clocks are coupled by a neuropeptide pathway in Drosophila
Animal circadian clocks consist of central and peripheral pacemakers, which are coordinated to produce daily rhythms in physiology and behaviour. Despite its importance for optimal performance andExpand
Cancer chemopreventive agents, 4-phenylcoumarins from Calophyllum inophyllum.
In a search for anti-tumor-promoting agents, we carried out a primary screening of ten 4-phenylcoumarins isolated from Calophyllum inophyllum L. (Guttiferae), by examining their possible inhibitoryExpand
Peripheral circadian clock for the cuticle deposition rhythm in Drosophila melanogaster
Insect endocuticle thickens after adult emergence by daily alternating deposition of two chitin layers with different orientation. Although the cuticle deposition rhythm is known to be controlled byExpand
Chemical constituents of Calophyllum brasiliensis: structure elucidation of seven new xanthones and their cancer chemopreventive activity.
The first study of chemical constituents of the stem bark of Calophyllum brasilienses collected in Brazil has led to the isolation and identification of seven new xanthones named brasixanthones AExpand
Isolation of the Antioxidant Pyranonigrin-A from Rice Mold Starters Used in the Manufacturing Process of Fermented Foods
Rice mold starters prepared from Aspergillus species are commonly used for the manufacture of koji in the production of oriental fermented foods. Methanol extracts of rice mold starters fermented byExpand
Chemical constituents of Glycosmis arborea: three new carbazole alkaloids and their biological activity.
As part of the phytochemical studies of the plant genus Glycosmis, the constituents of the plant Glycosmis arborea were investigated. Three new carbazole alkaloids named glybomines A (1), B (2), andExpand
Induction of apoptosis by carbazole alkaloids isolated from Murraya koenigii.
In the current study, we isolated 10 carbazole alkaloids from the plant species Murraya koenigii (Rutaceae), and examined their effects on the growth of the human leukemia cell line HL-60. ThreeExpand
Chemical constituents of Garcinia fusca: structure elucidation of eight new xanthones and their cancer chemopreventive activity.
We describe the isolation and spectrometric structure elucidation of eight new xanthones, fuscaxanthone A (1), B (2), C (3), D (4), E (5), F (6), G (7), and H (8), together with eight known xanthonesExpand
Chemical constituents of Clausena excavata: isolation and structure elucidation of novel furanone-coumarins with inhibitory effects for tumor-promotion.
A study of the chemical constituents of the leaves of Clausena excavata cultivated in a greenhouse led to the isolation and identification of 10 new furanone-coumarins named clauslactones A (1), BExpand
