Abstract: Design and synthesis of prodrugs of promising drug candidates represents a valid strategy to overcome the lack of favorable ADME properties, in particular aqueous solubility and bioavailability. We report herein the successful application of this strategy with two representative pyrazolo[3,4-d]pyrimidine derivatives (1 and 2), which led to the development of the corresponding and highly water-soluble antitumor prodrugs (7 and 8). In vitro studies confirmed a significant improvement of aqueous solubility and, for compound 8, good plasma stability, suggesting superior in vivo bioavailability. As expected, the uncleaved water-soluble prodrugs 7 and 8 showed no activity toward the enzymatic targets (c-Src and c-Abl) but revealed promising antiproliferative activity in myeloid cell lines, as a consequence of the in vitro hydrolysis of the selected solubilizing moiety, followed by the release of the active compounds (1 and 2).
