Preparation of pyrazolo 1 5 a pyridine and 1 2 4 triazolo 1 5 a pyridine derivatives from 1 6 diaminopyridine 2 thiones


, : Preparation of pyrazolo 1 5 a pyridine and 1 2 4 triazolo 1 5 a pyridine derivatives from 1 6 diaminopyridine 2 thiones. Heterocycles (Tokyo) 27(3): 733-744

The 1,6-diaminopyridine-2-thiones (1a and 1b) react with .alpha.-halocarbonyl compounds to given the phyrido [2,1-b] [1,3,4]thiadiazinium-salts (2) which undergo base-catalyzed ring-contraction to give the pyrazolo[1,5-a]pyridines (3) or (4). The reactions of the N-amino-heterocycles (1a and 1b) with nitriles lead direcetly to [1,2,4]triazolo-[1,5-a]pyridines (5).

L., 1997: Transport of protein kinase C isoforms to the nucleus of PC12 cells by nerve growth factor: Association of atypical zeta-PKC with the nuclear matrix. In an effort to understand the role of protein kinase C (PKC) in nerve growth factor-induced differentiation, we studied the expression of PKC using isoform-specific antibodies. Western blot analysis on whole cell lysates showed that alpha,beta- d...

To investigate the possibility that BBdp rats were more susceptible to diet-induced changes in islet homeostasis, BBdp rats were fed an NIH-07 (NIH) or hydrolysed-casein (HC) diet from 23 to 45 days of age. Compared with the standard diet, feeding...
