Human Mutation, 1996
Pyruvate kinase (PK) deficiency due to mutations of the PKLR gene is a common cause of hereditary nonspherocytic hemolytic anemia. Thus far, 55 different mutations have been described in patients with PK-deficient hemolytic anemia. Polymorphisms within the PKLR gene and in the tightly linked glucocerebrosidase (GBA) gene suggest that PK deficiency may ...

The reaction of pyruvates (3) with but-2-enyl-9-borabicyclo[3.3.1]nonane(2a) or its α-silyl and α-stannyl substituted derivatives (10) produced the threo-isomer [(4) or (11), respectively] stereoselectively; the latter reaction was applied to the ...

Assays of Pyruvate Dehydrogenase Complex and Pyruvate Carboxylase Activity
2011Pyruvate dehydrogenase complex (PDC) and pyruvate carboxylase (PC) are mitochondrial enzymes that provide the initial steps of the two main alternatives for pyruvate metabolism: oxidative decarboxylation vs. anaplerotic carboxylation, gluconeogenesis, and glycerogenesis.

A bimetallic cooperative catalysis model has been reported for the asymmetric Friedel-Crafts (F-C) alkylation of indoles with trifluoromethyl pyruvates using Trost's intramolecular dinuclear zinc complex as the catalyst.

The mechanism of photoinduced fragmentation of alkyl pyruvates
, 1982The finding that t-butyl pyruvate is photostable and has a much longer triplet lifetime than methyl, ethyl, isopropyl, 2-deuterioisopropyl, and benzyl pyruvates, together with triplet quenching studies, shows that alkyl pyruvates fragment from the ...

The role of electron transfer processes in the photoinduced decarboxylation of alkyl pyruvates
, 1984Irradiation of degassed solutions of alkyl pyruvates leads to the production of carbon dioxide, the yield of which is enhanced by the presence of electron acceptors, and in the case of methylviologen, the formation of reduced methylviologen is observed ...

Clinical Biochemistry, 1990
Pyruvate kinase (PK) deficiency was initially described by Valentine et al. in 1961. Since then, more than 300 cases have been described, including 65 in Japan. PK deficiency is the most common hereditary nonspherocytic hemolytic anemia among several red cell enzyme defects of the Embden-Meyerhof glycolytic pathway.

A simple and highly effective C-O(carboxylic) coupling reaction catalyzed by copper(I) salts has been developed to synthesize benzopyranones. The reaction of various 2-halobiarylcarboxylic acids was examined using microwave irradiation.
