S. Niwas et al., STRUCTURE-BASED DESIGN OF INHIBITORS OF PURINE NUCLEOSIDE PHOSPHORYLASE .5. 9-DEAZAHYPOXANTHINES, Journal of medicinal chemistry, 37(15), 1994, pp. 2477-2480
The synthesis and evaluation as inhibitors of purine nucleoside phosph
orylase of six 9-deazahypoxanthines (2a-f) are reported. In contrast t
o reports in the literature of other hypoxanthine-guanine analog pairs
, these inhibitors (2a-f) are equipotent with the corresponding 9-deaz
aguanines.
