Abstract
The present invention is novel 9-substituted-8-hydroxy or -8-halo-9 deazaguanines and pharmaceutical compositions and methods of use therefor. The derivatives are inhibitors of purine nucleoside phosphorylase selectively cytotoxic to T-cells but not to B-cells in the presence of 2'-deoxyguanosine and, therefore, are for use in the treatment of autoimmune diseases, gout, psoriasis or rejection of transplantation.
