The lateral line is a mechanosensory system used by fish to sense the movement of water. It is evolutionarily related to the inner-ear in humans. For both organisms, the binding of the CXCL12 (SDF-1 ligand) to the CXCR4 receptor induces conformational changes needed to activate signal transduction. This signaling results in numerous cellular responses such as cell fate, chemotaxis, and gene transcription. Interestingly, researchers have found that another signaling molecule, CXCL14, can also bind to the CXCR4 receptor with high affinity (Tanegashima et al., 2013). As a result, we hypothesize that CXCL14 modulates CXCL12-mediated chemotaxis, presumably acting as an allosteric …

Structure-activity relationships (SAR) in the aurone pharmacophore identified heterocyclic variants of the (Z)-2-benzylidene-6-hydroxybenzofuran-3(2H)-one scaffold that possessed low nanomolar in vitro potency in cell proliferation assays using various cancer cell lines, in vivo potency in prostate cancer PC-3 xenograft and zebrafish models, selectivity for the colchicine-binding site on tubulin, and absence of appreciable toxicity. Among the leading, biologically active analogs were (Z)-2-((2-((1-ethyl-5-methoxy-1H-indol-3-yl)methylene)-3-oxo-2,3-dihydrobenzofuran-6-yl)oxy)acetonitrile (5a) and (Z)-6-((2,6-dichlorobenzyl)oxy)-2-(pyridin-4-ylmethylene)benzofuran-3(2H)-one (5b) that inhibited in vitro PC-3 prostate cancer cell proliferation with IC50 values below 100 nM. A xenograft study in nude mice using …
