(2007)Two polymorphic forms of a mixed zinc/copper biquinoline dihydrogenphosphate are presented, showing almost identical monomeric units, viz. (2,2 '-biquinoline-kappa N-2,N ')bis(dihydrogenphosphato-kappa O)copper(II)/zinc(II), ...
-
(TAYLOR & FRANCIS INC, 2007)A series of C-3,4,5-substituted 2,6-dimethyl-1,4-dihydropyridines ( 1,4-DHPs) with pharmacological properties were prepared by a variation from the classical Hantzsch synthesis. The procedure involves treatment of the ...
-
(ELSEVIER SCI LTD, 2007)Two deteriorative pathways (autolysis and microbiological activity) were studied in farmed Coho salmon (Oncorhynchus kisutch) for 24 days during chilled storage. These changes were assessed by nucleotide degradation ...
-
(Sociedad Chilena de Cardiología y Cirugía Cardiovascular, 2007)Las estatinas son fármacos de elección para el tratamiento de hipercolesterolemia. Sin embargo, dado que existe una considerable variabilidad interindividual en la reducción del colesterol, la evaluación farmacogenética ...
-
(TAYLOR & FRANCIS INC, 2007)New benzothiophene arylpiperazine derivatives 8 (a-f) were synthesized as potential serotoninergic agents with 5-HT1A receptor affinity. Preparation of the derivatives was performed by treating N-[2-(chloromethyl)phenyl] ...
