A series of new N-phenylbenzamido acidderivatives was synthesized and evaluated for their ability to inhibit the IgE-mediated passive cutaneous anaphylaxis in the rat (PCA), as well as for their capacity to inhibit gastric mucosal damage induced by the oral administration of absolute alcohol in the rat. Some of these new derivatives exhibit potent antiallergic and cytoprotective activity, 20-80 times

Solvothermal reaction of zinc(II) and cadmium(II) salts with 5-propionamidoisophthalic acid (H2L1) and 5-benzamidoisophthalic acid (H2L2) in the presence or absence of an auxiliary ligand gives rise to a series of 1D, 2D and 3D Zn(II) or Cd(II) self-assembled metal–organic frameworks as revealed by X-ray diffraction structural analyses: [Zn(μ-L1-μ-1κOO′:2κO′′)(formamide)2]n (1), [Zn2(μ-L1-1κO:2κO′)2(4
