AB  - Glioblastoma (GBM), as the most aggressive brain tumor, displays a high expression of Src tyrosine kinase, which is involved in the survival, migration, and invasiveness of tumor cells. Thus, Src emerged as a potential target for GBM therapy. The effects of Src inhibitors pyrazolo[3,4-d]pyrimidines, Si306 and its prodrug pro-Si306 were investigated in human GBM cell lines (U87 and U87-TxR) and three primary GBM cell cultures. Primary GBM cells were more resistant to Si306 and pro-Si306 according to the 3-(4,5-Dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay. However, the ability of all GBM cells to degrade the extracellular matrix was considerably compromised after Si306 and pro-Si306 applications. Besides reducing the phosphorylation of Src and its downstream signaling pathway components, both compounds decreased the phosphorylated form of focal adhesion kinase (FAK) and epidermal growth factor receptor (EGFR) expression, showing the potential to suppress the aggressiveness of GBM. In vivo, Si306 and pro-Si306 displayed an anti-invasive effect against U87 xenografts in the zebrafish embryo model. Considering that Si306 and pro-Si306 are able to cross the blood-brain barrier and suppress the spread of GBM cells, we anticipate their clinical testing in the near future. Moreover, the prodrug showed similar efficacy to the drug, implying the rationality of its use in clinical settings.

AB  - Overexpression of P-glycoprotein (P-gp) and other ATP-binding cassette (ABC) transporters
in multidrug resistant (MDR) cancer cells is responsible for the reduction of intracellular drug
accumulation, thus decreasing the efficacy of chemotherapeutics. P-gp is also found at endothelial
cells’ membrane of the blood-brain barrier, where it limits drug delivery to central nervous system
(CNS) tumors. We have previously developed a set of pyrazolo[3,4-d]pyrimidines and their prodrugs
as novel Src tyrosine kinase inhibitors (TKIs), showing a significant activity against CNS tumors in
in vivo. Here we investigated the interaction of the most promising pair of drug/prodrug with P-gp
at the cellular level. The tested compounds were found to increase the intracellular accumulation
of Rho 123, and to enhance the efficacy of paclitaxel in P-gp overexpressing cells. Encouraging
pharmacokinetics properties and tolerability in vivo were also observed. Our findings revealed a
novel role of pyrazolo[3,4-d]pyrimidines which may be useful for developing a new effective therapy
in MDR cancer treatment, particularly against glioblastoma.
