We apply the atom-atom potentials to molecular crystals of iron(II) complexes with bulky organic ligands. The crystals under study are formed by low-spin or high-spin molecules of Fe(phen)(2)(NCS)(2) (phen = 1,10-phenanthroline), Fe(btz)(2)(NCS)(2) (btz = 5,5',6,6'-tetrahydro-4H,4'H-2,2'-bi-1,3-thiazine), and Fe(bpz)(2)(bipy) (bpz = dihydrobis(1-pyrazolil)borate, and bipy = 2,2'-bipyridine). Al...

The crystals under study are formed by low-spin or high-spin molecules of Fe(phen)2(NCS)2 (phen = 1,10-phenanthroline), Fe(btz)2(NCS)2 (btz = 5,5 0,6,60-tetrahydro4H,40H-2,20-bi-1,3-thiazine), and Fe(bpz)2(bipy) (bpz = dihydrobis(1-pyrazolil)borate, and bipy = 2,20-bipyridine). All molecula...
OBJECTIVE(S) Recently we reported that the soybean 15-lipoxygenase (SLO) inhibitory activity of pyrimido[4,5-b][l,4]benzothiazines largely depends on the orientation of sulfur atom of thiazine core towards Fe(III)-OH in the active site pocket of the enzyme with subsequent oxidation of sulfur to sulfoxide. In this paper the results of a comparative study on the SLO inhibitory activities of the m...
The 4-aminoquinoline naphthoquine (NQ) and the thiazine dye methylene blue (MB) have potent in vitro efficacies against Plasmodium falciparum, but susceptibility data for P. vivax are limited. The species- and stage-specific ex vivo activities of NQ and MB were assessed using a modified schizont maturation assay on clinical field isolates from Papua, Indonesia, where multidrug-resistant P. falc...
A morphological and quantitative study was performed on the respiratory epithelium of human distal airways in 20 lungs removed at operation for the treatment of carcinoma. Using 1 micron araldite sections stained with Toluidine Blue for light microscopy, with further electron microscopic study where required, we have described mast cells in the epithelium of bronchioles, terminal bronchioles, a...
Exposure of mice to the anesthetic gas N2O evokes a prominent antinociceptive effect that is sensitive to antagonism by nonselective nitric-oxide synthase (NOS) inhibitors. The present study was conducted to identify whether a specific NOS isoform is implicated in N2O antinociception in mice. In the abdominal constriction test, exposure of mice to 25, 50, and 70% N2O resulted in a concentration...
