The Role of a Glucal-Based Molecule in the Reduction of Pancreatic Adenocarcinoma—An In Vitro and In Silico Approach

Background/Objectives: Pancreatic cancer is the seventh most lethal type of cancer in the world, and its treatment, which is largely inefficient, is based on surgery and/or non-specific chemotherapy. Its malignant features are characterized by complex cell signaling pathways, which can be used as targets for new drugs. Methods: In this study, glucal-based compounds were synthetized, with substitution based on fluorine, nitrogen and aromatic ring addition. The compounds were tested in the pancreatic cell culture Mia-PaCa-2 and cell viability was assessed, with further IC50 calculation, stability and selectivity. Molecular docking was performed to evaluate the probable molecular target for 5b and in silico physicochemical properties were determined. Results: One molecule, named 5b, with two fluorine atoms inserted in the aromatic ring, exerted potent inhibitory activity on cell growth (IC50 = 1.39 µM), which was selective for pancreatic cells. Through molecular docking studies, the compound was found to be positioned in the active site of JAK3, indicating inhibition of such protein, which has a role in tumoral cell growth. Moreover, 5b was stable for 24 months and had physicochemical properties to permeate cell membranes, good oral absorption, and low potential to cause toxicity. Conclusions: These data suggest that 5b can be druggable and can be considered as a prototype for a new course of treatment in pancreatic cancer.
