Abstract:

Objective: A series of novel 2,4-diaminosubstituted pyrrolo[3,2-d]pyrimidines was synthesized together with their corresponding 7-phenyl or 7-isopropyl counterparts.

Results: Among the target derivatives, the 7-substituted analogues exhibited interesting cytotoxic activity against a panel of PI3Kα related human breast cancer cell lines, namely MCF7, T47D, MDA-MB-231 and HCC1954. Selected compounds were tested for potential PI3Kα inhibitory activity as well as for their cytotoxic effect in prostate cancer cell lines (DU145 and PC3).

Conclusion: Derivatives bearing a specific substitution pattern consisting of 7-phenyl as well as a 2-(4- aminocyclohexylamino) moiety (16c, 16f) display kinase inhibitory activity, elucidated on the basis of molecular simulation studies, which revealed their interaction with the DFG motif of the kinase.

Keywords: 9-deazapurine, pyrrolo[3, 2-d]pyrimidine, cytotoxicity, breast cancer, PI3K inhibition, docking scoring, molecular dynamics.
