Znâproline catalyzed aldolisation of glycoladehyde gave mainly tetroses whereas in the cross-aldolisation of glycoladehyde and rac-glyceraldehyde, pentoses accounted for 60% of the sugars formed with 20% of ribose.

prodrugs of L-cysteine (1a-h) were synthesized by the condensation of the sulfhydryl amino acid with naturally occurring aldose monosaccharides containing three, five, and six carbon atoms. The resulting 2-(polyhydroxyalkyl)thiazolidine-4(R)-carboxylicacids (TCAs) are capable of releasing L-cysteine and the sugars by nonenzymatic ring opening and hydrolysis. Thus, when added to rat hepatocyte preparations
iminosugars such as deoxynojirimycin (DNJ) or fagomine and other carbohydrates of low molecular weight by gaschromatography coupled to mass spectrometry (GC–MS) in Morus sp. Both oximation + trimethylsilylation and oximation + acetylation allowed the separation of target compounds, whereas trimethylsilyl (TMS) and acetylated derivatives showed several coelutions. Nevertheless, oximation + acetylation were
Adenosine analogues which act selectively at adenosine receptors and which act in general as adenosine antagonists are disclosed. From in vitro studies it is known that specific physiological effects can be distinguished as a result of this selectivity and that adenosine receptor activity in vitro correlates with adenosine receptor activity in vivo. Pharmaceutical preparations of the subject compounds can be prepared on the basis of the selective binding activity of the compounds disclosed herein which will enhance certain physiological effects while minimizing others, such as decreasing blood pressure without decreasing heart rate.
