A dipeptide conjugate of jasmonic acid, [N-( )-jasmonoyl]-Lalanyl -L-leucine, was prepared and its biological activities were investigated. The conjugate was active in the emission of linalool from rice leaves, while [N-( )-jasmonoyl]-D-alanyl-L-leucine was not. Neither conjugate was active in the production of sakuranetin. This is the first report of a biologically active dipeptide conjugate o...

Thiourea derivatives demonstrate potent cytotoxic activity against various leukemias and many tumor cell lines. In our previous study, the combination of thiourea and phosphonate has been proven as an effective strategy for developing antitumor agents. Herein, we synthesized and evaluated a series of novel chiral dipeptide thioureas containing an α-aminophosphonate moiety as antitumor agents. F...

This study describes methods for predicting and classifying voltage-gated ion channels. Firstly, a standard support vector machine (SVM) method was developed for predicting ion channels by using amino acid composition and dipeptide composition, with an accuracy of 82.89% and 85.56%, respectively. The accuracy of this SVM method was improved from 85.56% to 89.11% when combined with PSI-BLAST sim...

Hydrophobic dipeptide molecules can be used to create interfacial films covering bubbles and droplets made from a range of oils. At high pH, the dipeptide molecules form micelles which transform into a hydrogel of fibres in response to the addition of salt. We characterize the properties of the hydrogel for two different salt (MgSO4) concentrations and then we use these gels to stabilize interf...

Intestinal ischemia-reperfusion (IIR) injury affects other organs, like the liver. Glutamine may offer liver protection, following IIR injury. Four groups of rats were studied. In Group A, the animals were subjected to 90 minutes of IIR. In Group B Alanyl-Glutamine dipeptide was administered prior to IIR. Group C, was the sham, and in Group D, the animals were given Alanyl-Glutamine dipeptide, ...

Kumar, V., Ghai, 0. P., and Chase, H. P. (1971). Archives of Disease in Childhood, 46, 801. Intestinal dipeptide hydrolase activities in undernourished children. Intestinal dipeptide hydrolase enzymes cleave dipeptides into amino acids. In 8 undernourished children with diarrhoea, mean intestinal mucosal glyclyl-proline hydrolase activity was reduced 40%, valyl-proline hydrolase activity 38%, a...

Muramyl dipeptide, N-acetylmuramyl-L-alanine-D-isoglutamine (MDP), is the minimal biologically active subunit of bacterial peptidoglycan and elicits an acute inflammation in vivo. We now report that MDP is degraded by normal rat serum into its constituents, N-acetylmuramic acid and L-alanine-D- isoglutamine. The dipeptide is further degraded into its components L-alanine and D-isoglutamine. The...
