pittosporum eugenioides/悪性腫瘍

Pittosporum senacia (PS) Putt. (Pittosporaceae), indigenous to the Mascarene Islands, is a common ingredient in traditional medicines. However, there is currently a dearth of studies to validate some of these traditional claims. Given the broad traditional uses of PS against several diseases, we

The L-type amino acid transporter (LAT) family consists of four members (LAT1-4) that mediate uptake of neutral amino acids including leucine. Leucine is not only important as a building block for proteins, but plays a critical role in mTORC1 signaling leading to protein translation. As such, LAT

Three new acylated R1-barrigenol triterpene glycosides, 1-3, were isolated from the seeds of Pittosporum angustifolium Lodd. together with four known glycosides, 4-7, containing R1- and A1-barrigenol backbones. On the basis of spectroscopic, spectrometric, and chemical analyses the novel compounds

(1)H NMR fingerprints were used as the guiding principle for the isolation of minor compounds related to the l-type amino acid transporter inhibitors venulosides A (1) and B (2). Two new monoterpene glycosides, namely, venulosides C (3) and D (4), were isolated from a Queensland collection of the

The phytochemical investigation of the root barks of Pittosporum verticillatum Bojer subsp. verticillatum led to the isolation of three new triterpene saponins,

OBJECTIVE The purpose of this study was to evaluate the anticancer activity of 10 selected traditional Chinese medicinal plants on 4 cancer cell lines, namely MCF-7 (breast carcinoma), BALL-1 (acute lymphoblastic leukemia), Huh-7 (hepatocellular carcinoma), HeLa (cervical carcinoma) and their

Bioassay guided purification of the ethanolic extract of the bark of New Caledonian Pittosporum pancheri Brongn. and Gris (Pittosporaceae) led to the isolation and characterization of two new farnesyl monoglycosides, pancherins A and B. The structure of these compounds were determined on the basis

A novel triterpenoid saponin, pittoviridoside (1), which possesses an unusual 2,3,4-trisubstituted glycosidic linkage, has been isolated from Pittosporum viridiflorum using the engineered yeast strains 1138, 1140, 1353, and Sc-7 for bioactivity-guided fractionation. The structure of this compound

BACKGROUND Pittosporum viridiflorum Sims, a Pittosporaceae species, is used extensively in African traditional medicine (ATM) by various tribes. This review is an appraisal of the information concerning the description, distribution, conservation status, traditional uses, phytochemistry,
