Diamide insecticides with high efficacy against pests and good environmental safety are broadly applied in crop protection. They act at a poorly-defined site in the very complex ryanodine (Ry) receptor (RyR) potentially accessible to a fluorescent probe. Two N-propynyl analogs of the major anthranilic diamide insecticides chlorantraniliprole (Chlo) and cyantraniliprole (Cyan) were accordingly s...

in this paper, the structure of a new 16-membered macrocyclic schiff base compound n,n′-(3,3′-dimethoxy-2,2′-(propane-1,3-diyldioxy)dibenzylidene)propane-1,3-diamine, c22h26n2o4 (1), derived from 1,3-propanediamine and 3,3′-dimethoxy-2,2′-(propane-1,3-diyldioxy)dibenzaldehyde has been studied by single crystal x-ray diffraction, dft calculations at b3lyp/6-31g** and ft-ir spectroscopy. the titl...

Macrocyclic heterobinuclear Zn(II)–Cu(II) complexes with phenol based dicompartmental ligands possessing contiguous hexa- and penta-coordination sites were prepared by a stepwise procedure. The ligands include similar N4O2 and dissimilar N(imine)3O2 and N(amine)3O2 coordination sites sharing two phenolic oxygen atoms. The six-coordination site comprises two pyridyl pendant arms on the amine nit...

A resting culture of Rhizopus arrhizus (ATCC 11145) transformed verrucarin A into 16-hydroxyverrucarin A, whereas R. arrhizus transformed verrucarin B into a mixture of 16-hydroxyverrucarin B and 3'-hydroxyverrucarin A. Relative to verrucarins A and B, the 16-hydroxy derivatives showed marked increases in activity, as tested in vivo against P388 mouse leukemia.

A polycatenated HOF has been constructed from supramolecular embraced pairs of macrocyclic modules, featuring fluorescent detection nitrobenzene in water.

A modular synthetic approach was developed in which variation of the triplets of building blocks used enabled systematic variation of the macrocyclic scaffolds prepared. The approach was demonstrated in the synthesis of 17 diverse natural product-like macrocyclic scaffolds of varied (12-20-membered) ring size. The biological relevance of the chemical space explored was demonstrated through the ...

A new macrocyclic ligand (H2L) was synthesized by reaction of Acenaphthoquinone and oaminophenol. Then, its Co (II), Ni (II), Cu (II), Zn (II) and Cd (II) complexes were synthesized by the condensation method. Macrocyclic ligand (H2L) and Co(NO3)2.6H2O, Ni(NO3)2.6H2O, Cu(NO3)2.6H2O, ZnCl2.2H2O and CdCl2.2H2O respectively. The ligand and its complexes have been characterized by IR, H, UV–Vis spe...

Azacalix[5]pyridine, a heteroatom bridged calixaromatic with an odd number of arene units, and azacalix[10]pyridine, a giant molecular belt, were selectively synthesized based on a 2 + 3 macrocyclic coupling strategy; both novel macrocyclic hosts formed strong 1 : 1 complexes with fullerenes C60 and C70 in a size-selective manner with association constants up to 1.3 x 10(5) +/- 0.03 x 10(5) M(-1).
