By imitating the scaffold of lithocholic acid (LCA), a natural steroidal compound displaying Protein Tyrosine Phosphatase 1B (PTP1B) inhibitory activity, a series of stilbene derivatives containing phenyl-substituted isoxazoles were designed and synthesized. The structures of the title compounds were confirmed by 1H-NMR, 13C-NMR and HRMS. Activities of the title compounds were evaluated on PTP1B and the homologous enzyme TCPTP by using a colorimetric assay. Most of the target compounds had good activities against PTP1B. Among them, compound 29 (IC50 = 0.91 ± 0.33 μM), characterized by a 5-(2,3-dichlorophenyl) isoxazole moiety, exhibited an activity about 14-fold higher than the lead compound LCA and a 4.2-fold selectivity over TCPTP. Compound 29 was identified as a competitive inhibitor of PTP1B with a Ki value of 0.78 μM in enzyme kinetic studies.

3-Carboxybenzylphosphonic acid (H3L) (1), three complexes [Ca(H2L)2(H2O)3]n (2), [Ca(H2L)2(H2O)2]n (3) and [Ca(H2L)2(H2O)4] bipy (4) and two polymorphs of the salt (bipyH2)(H2L)2 (5, 6), were prepared and their structures were determined by single crystal X-ray diffraction analysis. Compounds 2 and 3 are polymeric species whereas 4 is a mononuclear complex. The calcium ion in 2, 3 and 4 is coordinated by monodeprotonated phosphonic groups (-PO3H-) and water molecules, the carboxylic group remains in the protonated form. The polymer chains or monomeric units are linked together by hydrogen bonds and ionic forces in the case of salts to afford three-dimensional layered supramolecular structures. Also the π...π stacking interactions in compounds 4, 5 and 6 contribute to the stabilization of the structures.
