The enantioselective construction of the 3-ethylindolo[2,3-a]quinolizidine moiety present in numerous indole alkaloids is reported, the key steps being a stereoselective cyclocondensation of (S)-tryptophanol with an appropriate racemic delta-oxoester and a regio- and stereoselective cyclization of the resulting oxazolopiperidones on the
Lambda-carrageenan, a linear high molecular weight sulfated polysaccharide, has been employed as a chiral selector in capillary electrophoresis for the separation of enantiomers of weakly basic pharmaceutical compounds. The racemic compounds that were enantioresolved included propranolol, pindolol, tryptophanol, laudanosine and
Bovine kidney cell lines resistant to tryptamine and tryptophanol (tryptophan analogs) were selected. The content of tryptophanyl-tRNA synthetase (WRS, EC 6.1.1.2) was assayed by measuring the binding of monospecific polyclonal antibodies to the 35S-labeled enzyme in detergent-soluble and -insoluble forms
Along with infections, ultrafiltration failure due to the toxicity of glucose-containing peritoneal dialysis (PD) solutions is the Achilles' heel of PD method. Triggered by the protective effect of general control nonderepressible-2 (GCN-2) kinase activation against high-glucose conditions in other cell

In Alzheimer's disease (AD) and other neurodegenerative disorders, proteins accumulate into ordered aggregates, called amyloids. Recent evidence suggests that these structures include both large, insoluble fibrils and smaller, prefibrillar structures, such as dimers, oligomers, and protofibrils. Recently, focus has shifted
