The redetermined structure of the title compound, [AuCl(C(15)H(11)N(3))]Cl(2)·3H(2)O, at 173 (2) K is reported. The structure displays O-H⋯Cl and O-H⋯O hydrogen bonding. The distance of one of the chloride ions from the gold(I) atom [5.047 (1) Å] differs from that determined previously.

Pyrrolo[2,1-f][1,2,4]triazin-4(3H)-ones 12 have been easily prepared via nucleophile-induced rearrangement of pyrrolooxadiazines 11 and regioselective intramolecular cyclization of 1,2-biscarbamoyl-substituted 1H-pyrroles 10. In this work, we demonstrated that the described synthetic approaches can be considered to be more facile and practical than previously reported procedures.

The title compound, C(10)H(11)NO(4), was formed from 4,1-benzoxazepine-2,5(1H,3H)-dione and ammonia gas. Intra-molecular hydrogen bonding is present between the amide N-H group and the carbonyl O atom of the ester group. The crystal structure features inter-molecular O-H⋯O hydrogen bonds.

Mouse peritoneal macrophages, loaded with cholesteryl ester by incubating with acetylated human low density lipoprotein containing [3H]cholesteryl oleate, were exposed to purified human apolipoproteins (apo) A-I, A-II, C-III, or E in aqueous solutions. Unesterified cholesterol was released into the medium in the presence of apoA-I, -A-II, or -E, accompanied by the decrease in intracellular chol...

In the present study we examined whether local transfer of intranasally administrated tritiated progesterone (3H-P4) would increase its concentration in blood supplying the brain and hypophysis in comparison with other organs. Additionally, the effect of estrous cycle on the P4 transfer was evaluated on isolated gilts' heads. In the first experiment 3H-P4 was instilled into the nasal cavities o...

Escherichia coli KG980, a vitamin B6 auxotroph derived from E. coli K12, utilized the three unphosphorylated forms of vitamin B6, more or less effectively, for growth, but did not utilize the three phosphate forms at concentrations ranging from 10(-7) to 10(-5) M in the minimum medium of Davis and Mingioli. The bacterium, however, utilized the phosphate forms, although less effectively than the...

Organophosphorus insecticides elicit toxicity by inhibiting acetylcholinesterase. Young animals are generally more sensitive than adults to these toxicants. A number of studies reported that some organophosphorus agents also bind directly to muscarinic receptors, in particular the m(2) subtype, in tissues from adult rats. As both the density and agonist affinity states of cardiac muscarinic rec...

a new mixed  halo chromate  nanoparticle compound was synthesised and characterized. triphenylphosphonium trifluoroiodochromate (iii)[p(c6h5)3h]+[crf3i]- nanoparticle was synthesized by using triphenylphosphonium  iodide reaction with crf3, in the presence of  3-mercaptopropionic acid. this method is a simple and direct method. the product was characterized by spectroscopic and analytical metho...
