Design and synthesis of silicon-containing tubulin polymerization inhibitors: Replacement of the ethylene moiety of combretastatin A-4 with a silicon linker

Silicon-containing combretastatin analogs were designed, synthesized and evaluated for stability and biological activities. Among them, compound 31 exhibited strong tubulin polymerization-inhibitory activity and very potent tumor cell growth-inhibitory activity (IC50 = 0.007 muM) in MCF-7 cell proliferation assay. This compound also potently inhibited [ 3H]colchicine binding (90.7% inhibition at 3 muM). These activities were comparable to those of combretastatin A-4 (CA-4) (1). In addition, compound 31 was physico-chemically more stable than 1. These results suggest that a silicon linker can act as a bioisoster of a cis carbon-carbon double bond.

Ligand-enabled methylene C(sp3)-H bond activation with a Pd(II) catalyst

Pd(II) insertion into beta-methylene C(sp3)-H bonds was enabled by a mutually repulsive and electron-rich quinoline ligand. Ligand tuning led to the development of a method that allows for installation of an aryl group on a range of acyclic and cyclic amides containing beta-methylene C(sp3)-H bonds.

Synthesis and structural characterization of a linkage isomer to a mononuclear Nickel(II) complex: Experimental and computational depiction of phosphoesterase efficiency

Synthesis and structural characterization of a linkage isomer, bis(2,2?-dipyridylamine)dithiocyanato(k-S)nickel(II), [Ni(dpa)2(k-SCN)2] (1) of a previously reported Ni(II) complex, [Ni(dpa)2(k-NCS)2] (dpa = 2,2?-dipyridylamine; SCN = thiocyanate) has been reported herein. X-ray structural analysis of 1 reveals that Ni(II) complex crystallizes in monoclinic system with P21/c space group and exists in trans configuration. The coordination geometry for 1 adopts a tetragonal structure. Supramolecular aspects of the Ni(II) complex indicate that N atom of SCN behaves as a donor and H atom of dpa ligand acts as a receptor in growing 1D crystalline structure along b axis in solid state. The aromatic rings in 1 prefer to exist in face-centred stacking with interplanar distance of 3.426 A and supports strongly to form self-assembled 3D crystalline architecture. Hirshfeld surface analysis further recommends this crystalline assembly in solid state. 1 exhibits promising phosphatase activity towards disodium(4-nitrophenyl)phosphate (PNPP) in aqueous-methanolic medium. The hydrolytic phosphatase efficiency for 1 is determined in terms of turnover number (kcat) as 3.38 ¡Á 104 h?1. Moreover, density functional theoretical computations closely replicate the structural parameters and spectroscopic behaviour of 1.

Carbohydrate specificity of a galectin from chicken liver (CG-16)

Owing to the expression of more than one type of galectin in animal tissues, the delineation of the functions of individual members of this lectin family requires the precise definition of their carbohydrate specificities. Thus, the binding properties of chicken liver galectin (CG-16) to glycoproteins (gps) and Streptococcus pneumoniae type 14 polysaccharide were studied by the biotin/avidin-mediated microtitre-plate lectin-binding assay and by the inhibition of lectin-glycan interactions with sugar ligands. Among 33 glycans tested for lectin binding, CG-16 reacted best with human blood group ABO (H) precursor gps and their equivalent gps, which contain a high density of D- galactopyranose(beta1-4)2-acetamido-2-deoxy-D-glucopyranose [Gal(beta1-4)GlcNAc] and Gal(beta1-3)GlcNAc residues at the non-reducing end, but this lectin reacted weakly or not at all with A-, H-type and sialylated gps. Among the oligosaccharides tested by the inhibition assay, the tri-antennary Gal(beta1-4)GlcNAc (Tri-II) was the best. It was 2.1 ¡Á 103 nM and 3.0 times more potent than Gal and Gal(beta1-4)GlcNAc (II)/Gal(beta1-3) GlcNAc(beta1-3)Gal(beta1-4)Glc (lacto-N-tetraose) respectively. CG-16 has a preference for the beta-anomer of Gal at the non-reducing end of oligosaccharides with a Gal(beta1-4) linkage > Gal(beta1-3) ? Gal(beta1-6). From the results, it can be concluded that the combining site of this agglutinin should be a cavity type, and that a hydrophobic interaction in the vicinity of the binding site for sugar accommodation increases the affinity. The binding site of CG-16 is as large as a tetrasaccharide of the beta-anomer of Gal, and is most complementary to lacto-N-tetraose and Gal(beta1-4)GlcNAc related sequences.

Preparation of analogues of Territrem B, a potent AChE inhibitor

The synthesis of analogues of the potent acetylcholinesterase inhibitor, Territrem B, was carried out starting from the naturally occurring jujubogenin glycosides. Dihydrojujubogenin-2-en-1-one (1), a dammarane derivative that possesses a skeleton and pharmacophore partially similar to those of Territrem B, was synthesized via three different paths. The derivative 21, which contains two potential pharmacophores, was also synthesized. The anti-AChE activity of the analogues was measured. The aromatic ring moiety seemed to be less important when compared with the 2-en-1-one pharmacophore. (C) 2000 Elsevier Science Ltd.
