momordica/tyrosine

Momordica charantia (MC) is a common oriental vegetable with known antidiabetic, laxative and antimicrobial properties. This study investigates the effects of aqueous fruit extract of MC on the transport of d-glucose, l-tyrosine and fluid across rat-everted intestine in vitro. Everted intestinal

Four new cucurbitane-type triterpene sapogenins, compounds 1-4, together with other eight known compounds were isolated from the acid-hydrolyzed fruits extract of Momordica charantia L. Their chemical structures were established by NMR, mass spectrometry and X-ray crystallography. Compounds 1-7 and

The increasing risk of variety of fatal diseases including diabetes mellitus is imposing serious challenge to chemist, biologists and clinicians. Due to the side effects of the chemotherapy, worldwide it is thinking that phyto-medicine are more effective to cope continuously increasing risk of fatal

The aim of this present study was to investigate the effect of bitter gourd extract on insulin sensitivity and proximal insulin signalling pathways in high-fat-fed rats. High-fat feeding of male Wistar rats for 10 weeks decreased the glucose tolerance and insulin sensitivity compared to chow-fed

The inhibitory effects of Momordica charantia extracts were studied on the uptake of glucose and tyrosine across rat everted gut sacs in vitro. The aqueous extract of the plant was found to inhibit primarily the uptake of glucose in a dose-dependent manner. Uptake of tyrosine was affected at high

A lectin has been isolated from Momordica charantia seeds and purified to homogeneity by affinity adsorption on a cross-linked arabinogalactan column and subsequent elution with 0.1 M lactose. In sedimentation velocity experiments an S20,W(O) degrees value of 6.5 S was obtained for the native lectin

Effects of chemical modifications on the protein-synthesis inhibitory (PSI) activities of momordin-a and luffin-a were investigated. Treatment with a 50-fold excess of diethylpyrocarbonate at pH 6.5 modified one histidine residue in momordin-a and luffin-a and reduced their PSI activities to 10% and

Insulin resistance is a causative factor for type 2 diabetes, whereas the development of insulin resistance is closely related to chronic inflammation induced by factors such as tumor necrosis factor-α (TNF-α). Momordica charantia, also known as bitter melon, has been used as an herbal medicine and
