CaGe» 9, zu denen LiGe audi hinsichtlich einer hetero­ polaren Formulierung nach K lem m und B u sm an n 10 zählt. Die Lithiumatome liegen in den Lücken dieser Ge­ rüststruktur. Mit ihnen gewinnt jedes Germaniumatom zusätzlich acht Lithiumnachbarn in einem Abstand von 2,64 Ä bis 3,24 Ä. Die Koordination um die Lithium­ atome ist der der Germaniumatome sehr ähnlich. Man beobachtet drei nächste g...

The dinuclear title compound, [Cd(2)(C(7)H(5)O(3))(4)(C(12)H(8)N(2))(2)], is located on a crystallographic rotation twofold axis. The two Cd(II) ions are connected by two tridentate bridging 2-hydroxy-benzoate anions. Each Cd(II) ion is seven-coordinated by five O atoms from three 2-hydroxy-benzoate ligands and two N atoms from 1,10-phenanthroline. The 2-hydroxy-benzoate mol-ecules adopt two ki...

Aims: The active form of vitamin D affects mineral homeostasis and bone metabolism. Stimulation effect of vitamin D in early pregnancy is effective for fetal-placental growth and development. The aim of this study is to investigate the relationship between 25-hydroxy vitamin D and initiation of labor. Materials & Methods: This study was conducted in Taleghani Hospital in Arak in 2008. 152 norma...

The selective synthesis of sulfonate surfactants with side chains containing ether- and hydroxy groups was carried out using cyclic sulfates as epoxide analogues. The main chain was elaborated from 1,2-dodecane sulfate by the addition of various hydroxy/alkoxysulfonates. Ethyleneoxy- and 1,2-propyleneoxy- groups were introduced using ethylene sulfate and 1,2-propylene sulfate, respectively.

An optically active helical poly(phenylacetylene) was synthesized by the copolymerization of phenylacetylenes bearing optically active hydroxy or ester groups obtained by the kinetic resolution of a racemic phenylacetylene with lipase; the helix-sense was inverted from one helix to another by the further chemical modification of the hydroxy groups with achiral bulky isocyanates or an acid chlor...

Yeehaw! The rotation of a visible-light-driven molecular motor based on barbituric acid is tamed by hydrogen bonding “lasso” mechanism between its serendipitously-formed tertiary hydroxy stereocentre and lower half carbonyl groups.

Orf virus, a member of the Parapoxvirus genus, causes a contagious pustular dermatitis in sheep, goats, and humans. Previous studies have demonstrated the activity of (S)-1-[3-hydroxy-2-(phosphonomethoxy)propyl]cytosine (HPMPC; cidofovir; Vistide) against orf virus in cell culture and humans. We have evaluated a broad range of acyclic nucleoside phosphonates (ANPs) against several orf virus str...
