Effects of 4-alkylaminopteridines on tobacco callus growth

Highly regioselective 6-exo-dig iodo/bromo cyclizations of functionalized 5-amino propargyl pyrimidinones: an efficient synthesis of functionalized pteridines

“…[3][4][5][6][7][8][9][10][11][12][13][14] Functionalized pteridines have also been explored for the treatment of broproliferative disorders, hepatitis C, 15,16 and vascular disorders, etc. 12,[17][18][19][20][21] A group of heterocyclic compounds known as pteridine, pyrazino [2,3-d] pyrimidines are composed up of condensed pyrimidine/pyrimidinone and pyrazine rings. 22 Most naturally produced pteridines referred to as pterins (II) or generally named as 2-amino-4(3H)pteridone belong to a family of nitrogen heterocyclic compounds.…”
