In the current study a series of novel furo[2,3-d]pyrimidine based-compounds were designed and synthesized as potential PI3K-α inhibitors. In accordance to the structure-activity relationship (SAR) studies of known PI3K-α inhibitors, different linkers including amide, urea and ether were attached to a piperazinyl furo[2,3-d]pyrimidine core. The synthesized compounds that revealed moderate PI3K-α inhibitory activity were tested for their anti-proliferative activities against pancreatic carcinoma on the PANC-1 cell line. Compounds 7b and 8a showed the highest anti-proliferative activity with IC50 values of 4.5 μM and 6 μM, respectively and relatively, the best in vitro PI3K inhibition ability within the newly synthesized compounds. Additionally, all the newly synthesized final compounds were tested on 60 human cancer cell lines. A docking study was carried out on the PI3K-α active site showing a comparable binding mode to that of FDA approved PI3K-α inhibitors. These newly discovered lipid kinase inhibitors could be considered as potential candidates for the development of new targeted anticancer agents.RSC advances32103-32112https://www.ebi.ac.uk/biostudies/studies/S-EPMC9056536biostudies-literatureElaborating piperazinyl-furopyrimidine based scaffolds as phosphoinositol-3-kinase enzyme alpha (PI3Kα) inhibitors to combat pancreatic cancer.PMC9056536Mansour MALasheen DSGaber HMAbouzid KAMfalseElaborating piperazinyl-furopyrimidine based scaffolds as phosphoinositol-3-kinase enzyme alpha (PI3Kα) inhibitors to combat pancreatic cancer.Phosphoinositol-3-kinase enzyme (PI3K) plays a crucial role in driving oncogenic growth in various mammalian cells, particularly pancreatic cells.
