The Red Sea sponge Hemimycale arabica afforded the known (Z)-5-(4-hydroxybenzylidene)-hydantoin (1), (R)-5-(4-hydroxybenzyl)hydantoin (2), and (Z)-5-((6-bromo-1H-indol-3-yl)methylene)-hydantoin (3). The natural phenylmethylene hydantoin (PMH) 1 and the synthetic (Z)-5-(4-(ethylthio)benzylidene)-hydantoin (4) showed potent in vitro anti-growth and anti-invasive properties against PC-3M prostate ...
Two new azide bound cobalt(III) complexes, [Co(L(1))(N3)3] (fac-1) and [Co(L(2))(N3)3] (mer-2), where L(1) is bis(2-pyridylmethyl)amine and L(2) is (2-pyridylmethyl)(2-pyridylethyl)amine, derived from tridentate reduced Schiff-base ligands have been reported. Interestingly, a methylene bridge regulated preferential coordination mode of ligands is noticed in their crystal structures: it is found...
Abstract Background & Aims: Hexamethylene diisocyanate is an aliphatic isocyanate and car painters are exposed to it. One of the most important disorders is occupational asthma. The aim of this study was to survey the effect of 1, 6 hexamethylene diisocyanate on the peak expiratory flow test to car painters in Isfahan. Materials & Methods: In this descriptive and a cross-sectional study the f...
Similar reactions of MnCl2·4H2O and CaCl2 with 2,6-bis(hydroxymethyl)-4-methylphenol gave heterometallic coordination clusters very different nuclearities, depending on the Mn:Ca ratio used. With a 1:1 ratio, hexanuclear cluster [MnIII3CaII3(μ3-Cl(HLMe)6(H2O)6]Cl2·6.74H2O (2) “triangle-in-triangle” topology was obtained. However, 2:1 resulted in [MnIII12MnIICaII6(μ4-O)8(μ3-Cl)3.7(μ3-η1-N3)4.3(H...
