In this study, we evaluated the anticancer effects of these cyclocoumarol derivatives for the first time. We tested their antiproliferative effects on several human cancer cell lines, including MDAMB231, A549, MCF7, SF268, HCT116, HeLa, and Jurkat. The MTT assay revealed that the methylated cyclocoumarol derivative, 2-methoxy-2-methyl-(1-(p-tolyl))-3,4-dihydropyrano [3,2-c] chromen-5(2H)-one, <strong>5b</strong> exhibited the most potent antiproliferative activity, particularly against MDAMB231 cells. Further investigations demonstrated that <strong>5b</strong> induced apoptosis in MDAMB231 cells via the mitochondrial pathway, as indicated by increased Bax and decreased Bcl2 levels, along with caspase-3 activation and PARP cleavage. Additionally, compound <strong>5b</strong> significantly inhibited the clonogenic potential of MCF7 cells and reduced the migration capacity of MDAMB231, SF268, and A549 cells.

IRAP is a member of the M1 family of zinc aminopeptidases and is abundantly expressed in areas of the brain associated with cognition, such as the amygdala, hippocampus and cerebral cortex. IRAP inhibitors were previously shown to enhance memory and learning in animal models. A comprehensive high throughput screening of 400,000 small molecules from the European Lead Factory library provided a series of 50 promising compounds in a qualified hit list (QHL). More than 30 IRAP inhibitors with an IC<sub>50</sub> below 3.5 μM were identified. Herein, selected compounds from this QHL were assayed for solubility and permeability. Most of the selected compounds displayed good solubility, but further permeability studies on the best compounds revealed low blood brain barrier (BBB) permeability and high efflux in cells overexpressing P-gp pumps, rendering them less promising as starting points in drug discovery processes. Two compounds from the QHL were prioritized for further structural optimization; the pyridyl-substituted isoxazole <strong>1a</strong> (<strong>QHL27</strong>) and the benzylhydroxamic acid derivative <strong>1b</strong> (<strong>QHL1</strong>), both demonstrating fair BBB permeability and no indication of efflux.
