Adenosine triphosphate (ATP) and norepinephrine (NE) interact in the control of blood flow in the kidney. A combined effect of NE and ATP has not been previously investigated at the level of the afferent arteriole (Af). We studied the effects of ATP on the contractile response of the Af to NE. Vascular reactivity to ATP, NE, and their combination was investigated in isolated perfused Af from mi...

The Tb atom of the title compound, TbHP(2)O(7)·4H(2)O, is coordinated by the O atoms of three symmetrically independent water mol-ecules and by five O atoms belonging to HP(2)O(7) (-) groups. The TbO(8) polyhedra are inter-connected by the diphospate anions, forming a three-dimensional network which is additionally stabilized by O-H⋯O hydrogen bonding between water mol-ecules and O atoms of the...

The title compound, C(7)H(9)N(3)S(2), crystallizes with two unique mol-ecules in the unit cell, both present as thio-semicarbazide tautomers. The mol-ecules differ principally in the dihedral angles between the thio-phene ring planes and the planes through the non-H atoms of the hydrazinecarbothio-amide units, viz. 9.80 (8)° for one mol-ecule and 19.37 (7)° for the other. The hydrazinecarbothio...

AIM:To investigate the relationship between alanyl-glutamine (ALA-GLN) and glutathione (GSH) biosynthesis in hepatic protection.METHODS:Twenty male Wistar rats were randomly divided into two groups:one receiving standard parenteral nutrition (STD) and the other supplemented with or without ALA-GLN for 7 days. The blood and liver tissue samples were examined after 5-fluorouracil (5-FU) was injec...

The title Schiff base compound, C(15)H(14)N(2)O(2), consists of two crystallographically independent mol-ecules, A and B. Mol-ecule A is almost planar, whereas mol-ecule B is slightly twisted, the dihedral angles between the benzimidazole group and the benzene rings being 2.65 (12) and 13.17 (15)°, respectively. The methyl group of mol-ecule B is disordered over two positions, with a refined si...

In the asymmetric unit of the title nicotinonitrile derivative, C(23)H(21)BrN(2)O(4), there are two non-planar independent mol-ecules. The central pyridine ring makes dihedral angles of 9.05 (7) and 77.06 (7)°, respectively, with the 4-bromo-phenyl and 2,4,6-trimethoxy-phenyl rings in one mol-ecule, whereas the corresponding values are 5.96 (7) and 82.37 (7)° in the other. All the three meth-ox...

The title solvated ester, C(22)H(29)NO(3)S·0.5C(6)H(14), crystallizes with two independent mol-ecules along with a hexane mol-ecule in the asymmetric unit. The two aromatic rings are separated by an -CH(2)-S- linkage; the rings are aligned at 83.27 (4)° in one mol-ecule and 47.66 (7)° in the other. The hy-droxy group of one mol-ecule forms an O-H⋯O hydrogen bond to the other mol-ecule.

1. BDF 9148 is a newly synthesized congener of DPI 201-106 in which the piperazidinyl moiety has been replaced by an azetidine-3-oxy-moiety. The inotropic effect of both drugs was studied as well as their influence on the action potential, by use of standard microelectrode techniques. 2. BDF 9148 increased the contractile force of guinea-pig atria and papillary muscles. The EC50 was 1.32 X 10(-...
