Characterization of Underivatized Pterins by Laser Desorption Fourier Transfonn Mass Spectrometry
Pteridines, 1993 Laser desorption FfMS provides a powerful method for examining the structures of underivatized pteridines. (M + Na)+ and (M + K)+ ions are generated by laser desorption and can be used to determine molecular weights. The negative ion spectra provide more

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 ...

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