Synthesis, structure and photophysical properties of novel thiazolo[2,3-b]pteridines

Acta Chimica Slovenica
A one-pot synthesis of a series of thiazolo[2,3-b]pteridines, along with an alternative step-by-step procedure, has been developed. The regioselectivity of the heterocyclization was determined using a combination of physicochemical methods, including X ...

6-Acetonylisoxanthopterin: A Potent Inhibitor of Sepiapterin Reductase

Pteridines, 1991
The inhibitory effect of 6-/7-substituted (2'-oxo) pteridines and ichthyopterin was examined for sepiapterin reductase. 6-Acetonylisoxanthopterin and 6-acetonyl-2,4-diamino-7-hydroxypteridine showed pronounced competitive inhibitory effects to ...
