A novel 1:1 complex of potassium mikanin-3-O-sulfate with methanol.

Mikanin-3-O-sulfate (1), in the form of its potassium salt, together with mikanin (2) and alpinetin (3) were isolated from Mikania micrantha. The crystal structures of K(1) x CH3OH, 2 and 3 x H2O were established by X-ray crystallography. The potassium ions in K(1) x CHO3H are bridged by O5, O7 and O8 to form a chain of face-sharing KO8 coordination polyhedra, from which the aglycon units are o...

A Novel Role for 3-O-Sulfated Heparan Sulfate in Herpes Simplex Virus 1 Entry

Herpes simplex virus type 1 (HSV-1) binds to cells through interactions of viral glycoproteins gB and gC with heparan sulfate chains on cell surface proteoglycans. This binding is not sufficient for viral entry, which requires fusion between the viral envelope and cell membrane. Here, we show that heparan sulfate modified by a subset of the multiple D-glucosaminyl 3-O-sulfotransferase isoforms ...

catena-Poly[[(μ-3-hy­droxy­benzoato-κ3 O 1,O 1′:O 3)(μ-3-hy­droxy­benzoato-κ3 O 1,O 1′:O 1)(isonicotinamide-κN 1)­lead(II)] monohydrate]

In the crystal of the title polymeric compound, {[Pb(C(7)H(5)O(3))(2)(C(6)H(6)N(2)O)]·H(2)O}(n), the Pb(II) ion is chelated by two carboxyl-ate groups of 3-hy-droxy-benzoate (HB) anions, and coordinated by one isonicotinamide mol-ecule; a carboxyl-ate O atom and a hy-droxy O atom from adjacent HB anions bridge the Pb(II) ion to form polymeric chains along [100], in which the Pb(II) ion is in an...

A Novel Approach for Preparation of Acetylacetonate Complex Anchored to High Order Nanoporous Silica (LUS-1)

Tris(3-bromo-acetylacetonato) chromium(III) as an inert and very stable complex with a good leaving group was synthesized using as-prepared Cr(acetylacetonate)3. Highly ordered nanoporous silica (LUS-1), with some great features, was functionalized with 3-aminopropyltriethoxysilane. Then the as-prepared product was modified with tris(3-bromo-acetylacetonato) chromium(III) under mild reaction co...

(2-Methyl-4-oxo-4H-pyran-3-olato-κ2 O 3,O 4)bis­(triphenyl­phosphane-κP)copper(I)–triphenyl­phosphane–methanol (1/1/1)

In the title compound, [Cu(C(6)H(5)O(3))(C(18)H(15)P)(2)]·C(18)H(15)P·CH(3)OH, the pyran-4-one ring is appromimately planar (r.m.s deviation = 0.0138 Å), with the Cu(I) atom 0.451 (5) Å out of the plane. The Cu(I) atom has a distorted tetra-hedral coordination. The O-Cu-O angle is 80.07 (8)° and the P-Cu-P angle is 123.49 (3)°. The crystal packing is stablized by intra-molecular C-H⋯O inter-act...
