1 Investigation of cooperativity in the binding of ligands to the D 2 dopamine receptor. Abstract The D 2 dopamine receptor exists as dimers or as higher order oligomers, based on data from physical experiments. In this study we have sought evidence that this oligomerisation leads to cooperativity by examining the binding of three radioligands ([ 3 H]nemonapride, [ 3 H]raclopride, [ 3 H]spipero...

acrjourna understanding of the anatomy and development of fetal and adult hair follicles and the molecular of the major embryonic pathways that regulate the hair follicle have led to exciting discoveries rning the development of basal cell carcinoma (BCC). These studies have shed light on the major f Sonic hedgehog (Shh) signaling and its interactions with the insulin-like growth factor (IGF) a...

There are two symmetry-independent mol-ecules, A and B, in the asymmetric unit of the title compound, C(17)H(14)FIO(3)S. The dihedral angle formed by the 4-fluoro-phenyl ring and the mean plane [r.m.s. deviation = 0.013 (2) Å in mol-ecule A and 0.016 (2) Å in mol-ecule B] of the benzofuran fragment is 57.71 (7)° in mol-ecule A and 44.95 (7)° in mol-ecule B. In the crystal, mol-ecules are linked...

The title compound, C10H12Cl3NTe, crystallizes with two crystallographically independent mol-ecules (A and B) in the asymmetric unit. In each case, the coordination around the Te atom is distorted square-pyramidal, with the equatorial plane composed of the three Cl atoms and the C atom of the pyridinium ring. The Te atom is displaced from the mean-square plane by 0.1926 (7) and 0.1981 (8) Å, in...

Background & Aim: Ocimum basilicum L. is belong to the Lamiaceae family which is cultivated as a culinary, industrial and medicinal plants in some countries from thousands years ago. The seed of this plant is rich in poly un-saturated fatty acids (PUFA) and produced a large amount of mucilage. Experimental: The oil of seed was extracted separately and converted to fatty acids...

abstract the utility of carbon paste electrode for the determination of flavoxate hcl modified with flavoxate-tetraphenylborate (flx-tpb) and flavoxate-phosphotungestic acid (flx-pta) ion-pairs in batch mode is demonstrated. the electrodes revealed a nernstian response over a wide concentration ranges 1.39×10-5-1x10-2 mol l-1 and1×10-5-1x10-2 mol l-1 using flx-tpb and flx-pta, respectively. the...

The asymmetric unit of the title compound, C(20)H(24)N(2)OS, consists of two crystallographically independent mol-ecules. In each mol-ecule, an intra-molecular N-H⋯O hydrogen bond forms an S(6) ring motif. The dihedral angles between the terminal benzene rings in the two mol-ecules are 75.52 (7) and 42.80 (7)°. In the crystal, inter-molecular N-H⋯S inter-actions link the mol-ecules into a chain...

Abstract The utility of carbon paste electrode for the determination of flavoxate HCl modified with flavoxate-tetraphenylborate (FLX-TPB) and flavoxate-phosphotungestic acid (FLX-PTA) ion-pairs in batch mode is demonstrated. The electrodes revealed a Nernstian response over a wide concentration ranges 1.39×10-5-1x10-2 mol L-1 and1×10-5-1x10-2 mol L-1 using FLX-TPB and FLX-PTA, respectively. The...
