Scientists have completed large-scale tests on a new type of five-minute urine test that measures the health of a person’s diet, and produces an individual’s unique urine ‘fingerprint’. Scientists at Imperial College London in collaboration with colleagues at Northwestern University, University of Illinois, and Murdoch University, analysed levels of 46 different so-called metabolites in the…

In this articale, we have described a new practical cyclocondensation synthesis for a series of [1,2,4]triazolo[4,3-c]pyrido[3,2-e] pyrimidine and pyrido[2′,3′:4,5] pyrimido[6,1-c][1,2,4] triazine from 2-amino-3-cyano-4.6-diarylpyridines. Also polyheterocyclic compounds containing [1,2,4]triazolo and [1,2,3,4]tetrazolo moieties were also synthesized through the reactions of 3-hydrazino-8,10-diaryl [1,2,4]triazolo[4,3-c]pyrido[3,2-e]pyrimidine with both formic acid and the formation of diazonuim salt respectively . Newly synthesized heterocycles…
