Abstract
Toll-like receptor (TLR) 2 is a transmembrane receptor that participates in the innate immune response by forming a heterodimer with TLR1 or TLR6. TLR2 agonists play an important role in tumor therapy. Herein, we synthesized a series of 3-(2H-chromen-3-yl)-5-aryl-1,2,4-oxadiazole derivatives and identified WYJ-2 as a potent small and selective molecule agonist of TLR2/1, with an EC50 of 18.57 ± 0.98 nM in human TLR2 and TLR1 transient-cotransfected HEK 293T cells. WYJ-2 promoted the formation of TLR2/1 heterodimers and activated the nuclear factor kappa B (NF-κB) signaling pathway. Moreover, our study indicated that WYJ-2 could induce pyroptosis in cancer cells, mediated by activating the NOD-like receptor pyrin domain containing 3 (NLRP3) inflammasome. WYJ-2 exhibited effective anti-non-small cell lung cancer (NSCLC) activity in vitro and in vivo. The discovery that activating TLR2/1 induces pyroptosis in cancer cells may highlight the prospects of TLR2/1 agonists in cancer treatment in the future.

Abstract
We unveiled superior base mediators for the annulative condensation of salicylaldehydes and acrylonitrile to give 3-cyano-2H-chromenes, which has been mediated only by 1,4-diazabicyclo[2.2.2]octane (DABCO) over the past two decades. The reactions were most efficiently mediated by 4-dimethylaminopyridine (DMAP), which yielded 3-cyano-2H-chromenes in higher yields than DABCO in most cases. We also confirmed that the reaction remained high yielding in a decagram-scale experiment with a catalytic amount of DMAP. The utility of this reaction was also exemplified by derivatization of an obtained 3-cyano-2H-chromene into a known 2H-chromene-3-carboxylic acid, which was previously synthesized with a non-readily available reagent.

Abstract
A series of new benzofuran/oxadiazole hybrids (8a-n) was synthesized from 2H-chromene-3-carbonitriles (3a-c) through the multistep synthetic methodology, and these hybrids are known to exhibit anticancer activities. All the compounds were evaluated for their in vitro cytotoxicity against the HCT116 and MIA PaCa2 cell lines. Compounds 6a (IC50 : 9.71 ± 1.9 μM), 6b (IC50 : 7.48 ± 0.6 μM), and 6c (IC50 : 3.27 ± 1.1 μM) displayed a significant cytotoxic activity, whereas compounds 8d and 8e exhibited good activity against both cell lines. The depletion of glycogen synthase kinase-3β (GSK3β) induces apoptosis through the inhibition of basal NF-κB activity in HCT116 colon cancer cells and MIA PaCa2 pancreatic cancer cells. Molecular docking of compounds 6a, 6b, 6c, 8d, and 8e with GSK3β demonstrated the best binding affinity, correlating with the biological activity assay. Furthermore, the structure-activity relationship of these novel compounds reveals promising features for their use in anticancer therapy.
