Substituted pyrrolo(2,3-D)pyrimidines for selectively targeting tumor cells with fr-alpha and fr-beta type receptors

摘要

Pyrrolo[2,3-d]pyrimidine derivatives, and pharmaceutical acceptable salts thereof, useful in therapeutically treating patients with cancer are disclosed. These compounds selectively target folate receptors (FR) of cancerous tumor cells and inhibit purine synthesis and hence, DNA synthesis.
