The 1,3,4-oxadiazinane ring in the title compound, C(18)H(18)N(2)O(4), is in a twisted boat conformation. The two carbonyl groups are orientated towards the same side of the mol-ecule. The dihedral angle between the planes of the benzene rings is 76.6 (3)°. Mol-ecules are sustained in the three-dimensional structure by a combination of C-H⋯O, C-H⋯π and π-π [shortest centroid-centroid distance =...

The title compound crystallized as an ethanol solvate, C(18)H(18)N(3)OP·C(2)H(6)O. It is the reduction product of tris-(3-nitro-phen-yl)phosphine oxide. In the crystal, there are inter-molecular N-H⋯O hydrogen bonds between neighbouring tris-(3-amino-phen-yl)phosphine oxide mol-ecules and O-H⋯O hydrogen bonds involving the ethanol solvent mol-ecule.

The title compound, [Cd(C44H28N4)(H2O)]·(C12H24O6), was made by the reaction of the [Cd(TPP)] with an excess of 18-crown-6 in chloro-benzene (where TPP is tetra-phenyl-porphyrinate). The Cd(II) cation is chelated by a TPP anion and coordinated by a water mol-ecule in a distorted N4O square-pyramidal geometry, the Cd(II) cation being displaced by 0.7533 (9) Å from the mean plane of four N atoms ...

The concept of selective receptor modulators has been established for the nuclear steroid hormone receptors. Such selective modulators have been utilized therapeutically with great success in the treatment of cancer. However, this concept has not been examined with regard to the aryl hydrocarbon receptor (AHR) because of the latent toxicity commonly associated with AHR activation. AHR-mediated ...

The title compound (systematic name: cis-anti-cis-2,5,8,15,18,21-hexa-oxatri-cyclo-[20.4.0.0(9,14)]hexa-cosane aceto-nitrile disolvate), C20H36O6·2CH3CN, crystallizes from an aceto-nitrile solution of di-cyclo-hexane-18-crown-6 on evaporation. The mol-ecule is arranged around a center of symmetry with half the crown ether mol-ecule and one mol-ecule of aceto-nitrile symmetry independent. All O-...

In the title compound, [Zn(C44H28N4)]·C12H24O6, the Zn(II) ion lies on an inversion center and the asymmetric unit contains one half of a Zn(TPP) complex (TPP = 5,10,15,20-tetra-phenyl-porphyrin dianion) and one half of a centrosymmetric 18-crown-6 mol-ecule. The Zn(TPP) complex exhibits a nearly planar conformation of the porphyrin core [maximum deviation = 0.106 (2) Å] with an average Zn-N di...

The title compound, C21H18N2O4, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. In both mol-ecules the oxazine ring has an envelope conformation with the hydroxyl-substituted C atom as the flap. The nitro-benzyl ring and the phenyl ring are almost normal to the mean plane of the benzooxazine ring system with dihdral angles of 85.72 (15) and 82.69 (15)°, respective...

Adipose-derived stem cells (ASCs) are considered a great alternative source of mesenchymal stem cells (MSCs). Unlike bone marrow stem cells (BMSCs), ASCs can be retrieved in high numbers from lipoaspirate, a by-product of liposuction procedures. Given that ASCs represent an easily accessible and abundant source of multipotent cells, ASCs have garnered attention and curiosity from both scientifi...
