Synthesis and Enzymic Hydrolysis of Acylated Adenosine Derivatives
Various derivatives of adenosine were prepared by acylation of adenosine (6-amino-9-(bD-ribofuranosyl)purine (1) with different molar equivalents of acetic anhydride and/or pivaloyl chloride in pyridine. Compounds 6-acetylamino-9-[(2,3,5-tri-O-acetyl)-b-Dribofuranosyl]purine (3), 6-amino-9-[(2,3,5-tri-O-acetyl)-b-D-ribofuranosyl]purine (4), and 6-pivaloylamino-9-[(2,3,5-tri-O-pivaloyl)-b-D-ribo...
متن کاملAcylated Steryl Glycoside Synthesis in Seedlings of Nicotiana tabacum L.
In tobacco seedlings (Nicotiana tabacum L.), glucose from supplied uridine diphosphate-[U-(14)C]glucose was first incorporated into steryl glycosides and later into acylated steryl glycosides. However, when [(14)C]cholesterol was used as substrate, the acylated steryl glycosides became labeled earlier than the steryl glycosides. With [(14)C]cholesteryl glucoside as substrate, most of the radioa...
متن کاملExceedingly Efficient Synthesis of (±)-Grandifloracin and Acylated Analogues.
A highly efficient regio- and stereoselective total synthesis of (±)-grandifloracin via a tandem dearomative epoxidation/spontaneous Diels-Alder cyclodimerization from salicylic acid in only four steps is reported. The synthetic route allows for late-stage diversification of the core structure to give ready access to analogues of this promising agent against pancreatic cancer.
متن کاملThe influence of resistance and aerobic exercise on hunger, circulating levels of acylated ghrelin and peptide YY in healthy males
Resistance (muscle strengthening) exercise is a key component of exercise recommendations for weight control yet very little is known about the effects of resistance exercise on appetite. We investigated the effects of resistance and aerobic exercise on hunger and circulating levels of the gut hormones acylated ghrelin and peptide YY (PYY). Eleven healthy male students: age 21.1 ± 0.3 y, body m...
متن کاملAcylated and Desacylated Ghrelin, Preptin, Leptin, and Nesfatin-1 Peptide Changes Related to the Body Mass Index
This study examines the levels of acylated and desacylated ghrelin, preptin, leptin, and nesfatin-1 peptide changes related to the body mass index (BMI). The subjects were allocated to 5 groups depending on their BMIs as follows: Group I (BMI <18.5 kg/m(2)); Group II (BMI 18.5-24.9 kg/m(2)); Group III (BMI 25-29.9 kg/m(2)); Group IV (BMI 30-39.9 kg/m(2)); Group V (BMI >40 kg/m(2)). Serum acylat...
