Heparan sulfate proteoglycans (HSPGs) have long been implicated in a wide range of cell-cell signaling and cell-matrix interactions, both in vitro and in vivo in invertebratemodels. Althoughmanyof the genes that encode HSPG core proteins and the biosynthetic enzymes that generate and modify HSPG sugar chains have not yet been analyzed by genetics in vertebrates, recent studies have shown that H...
متن کامل1H-Benzimidazol-2-ylmethyl phenyl ether
There are two mol-ecules in the asymmetric unit of the title compound, C(14)H(10)N(2)O: the dihedral angles between their aromatic ring planes are 47.4 (4) and 46.8 (3)°. In the crystal structure, mol-ecules are linked by N-H⋯N hydrogen bonds from the secondary nitro-gen N-H donor to the tertiary N-atom acceptor of a symmetry-related neighbour, resulting in hydrogen-bonded chains. The two indep...
متن کاملN-(2-aminobenzyl)-N,N-bis(quinolin-2-ylmethyl)amine.
The title new diquinaldine derivative, C27H24N4, forms molecular assemblies organized by intermolecular quinoline pi-pi stacking [3.356 (3) and 3.440 (3) A] and both inter- and intramolecular N-H...N hydrogen bonds [3.039 (3)-3.104 (3) A and 129 (2)-172 (2) degrees]. The combination of such interactions provides readily definable contacts that propagate along each crystallographic axis.
متن کامل[(E)-1-(Naphthalen-2-yl)ethylidene](naphthalen-1-ylmethyl)amine
The title compound, C(23)H(19)N, was obtained unexpectedly from the reaction of [Eu(nta)(3)(PzPy)] {Hnta = 1-(2-naphtho-yl)-3,3,3-trifluoro-acetone and PzPy = 2-[3(5)-pyrazol-yl]pyridine} with 1-naphthyl-methyl-amine. The 1- and 2-naphthyl groups are essentially planar [r.m.s. deviations of 0.007 and 0.011 Å, respectively] and subtend angles of 38.69 (11) and 16.50 (11)°, respectively, with the...

The title compound, C(20)H(31)NO(5), was synthesized from 9α-hy-droxy-parthenolide (9α-hy-droxy-4,8-dimethyl-12-methylen-3,14-dioxa-tricyclo-[9.3.0.0(2),(4)]tetra-dec-7-en-13-one), which was isolated from the chloro-form extract of the aerial parts of Anvillea radiata. The mol-ecule is built up from fused five-and ten-membered rings with the pipyridin-1-yl-methyl group as a substituent. The ten...
