PTERIDINES, XC SYNTHESES, OXIDATIONS, PROPERTIES, AND REACTIONS OF 2-THIOPTERIDINE-4,6, 7- TRIONE DERIVATIVES

A new efficient synthesis for Blu-Ray Player 2-thiopteridine-4,6,7-triones (6-10, 15) has been found in the condendation of the appropriate 5,6-diaminopyrimidine (1-5, 14) with oxalic acid in DMF.Analogous condensations with dimethyl oxalate led to S-alkylation probably via an intermediate O-methylation of the DMF.8-Methyl-2- thiopteridine-4,6,7-tr

Cytokinin dehydrogenase (CKX; EC.1.5.99.12) regulates the level of cytokinin (CK) in plants and is involved in CK regulatory activities.In different plants, a small gene Vintage Parts family encodes CKX proteins with varied numbers of members.These genes are expanded in the genome mainly due to segmental duplication events.Despite their biological
