I-35: Induction of Ovulation in Clomiphen Resistant
Polycystic ovary syndrome (PCOS) is a heterogeneous disorder in which chronic anovulation is a common feature despite the presence of multiple micro- structures in the ovaries. A growing body of evidence has suggested that serum hyperinsulinemia and as the result hyperandrogenemia contributes to the excess ovarian androgen secretion observed in women with PCOS. The standard therapy for anovulat...
متن کاملCrystal structure of tetraaquabis(1,3-dimethyl-2,6-dioxo-7H-purin-7-ido-κN 7)cobalt(II)
The title complex, [Co(C7H7N4O2)2(H2O)4], comprises mononuclear mol-ecules consisting of a CoII ion, two deprotonated theophylline ligands (systematic name: 1,3-dimethyl-7H-purine-2,6-dione) and four coordinating water mol-ecules. The CoII atom lies on an inversion centre and has a slightly distorted octa-hedral coordination environment, with two N atoms of two trans-oriented theophylline ligan...
متن کاملCrystal structure of (1S,2R)-6,6-dimethyl-4,8-dioxo-2-phenylspiro[2.5]octane-1-carbaldehyde
In the title compound, C17H18O3, the two non-spiro C atoms of the cyclo-propane ring bear a formyl and a phenyl substituent which are trans-oriented. In the crystal, mol-ecules are linked by weak C-H⋯O and C-H⋯π contacts resulting in a three-dimensional supra-molecular structure.
متن کاملCrystal structure of trimethylammonium 5-(2,4-dinitrophenyl)-1,3-dimethyl-2,6-dioxo-1,2,3,6-tetrahydropyrimidin-4-olate
The asymmetric unit of the title mol-ecular salt, C3H10N(+)·C12H9N4O7 (-) [alternative name: tri-methyl-ammonium 5-(2,4-di-nitro-phen-yl)-1,3-dimethyl barbiturate], contains one anion and two half-occupancy cations. The cations are disordered about inversion centres. The tetra-hydro-pyrimidine ring is essentially planar [maximum deviation = 0.007 (2) Å] and forms a dihedral angle of 41.12 (6)° ...
متن کاملCrystal structure of tetraaquabis(1,3-dimethyl-2,6-dioxo-3,7-dihydro-1H-purin-9-ido)magnesium
The title complex, [Mg(C7H7N4O2)2(H2O)4], lies across an inversion centre and the Mg(II) atom is coordinated in a slightly distorted octa-hedral environment by four aqua ligands in the equatorial sites and two 1,3-dimethyl-2,6-dioxo-3,7-di-hydro-1H-purin-9-ide ligands, through imidazole ring N atoms, in the axial sites. An intra-molecular O-H⋯O hydrogen bond forms an S(7) graph-set motif. In th...
