Transplantation, 58(12), 1303-1308 (1994-12-27)
Compound BW B70C, a selective 5-lipoxygenase inhibitor was tested for its ability to reduce inflammatory damage in an in vivo rabbit model of renal storage and transplantation. Kidneys were stored at 0-2 degrees C for 48 hr prior to autografting.

European journal of pharmacology, 324(1), 89-98 (1997-04-11)
The interference of the 5-lipoxygenase inhibitor, BW B70C ((E)-N-(3-[3-(4-fluorophenoxy)phenyl]-1(R,S)-methyl prop-2-enyl)-N-hydroxyurea), with Escherichia coli lipopolysaccharide (endotoxin)-induced lung leucocyte sequestration and microvascular albumin exchanges was evaluated in the anaesthetised guinea-pig using radioactive tracers, in parallel to the effects on cell counts in

Toxicology and applied pharmacology, 146(2), 299-308 (1997-11-05)
In a study of structure-activity relationship with drug-induced nephropathy two lipoxygenase inhibitors, the N-hydroxyurea derivative 70C ((E)-N-{3-[3-(4-fluorophenoxy) phenyl]-1-(R, S)-methylprop-2-enyl}-N-hydroxyurea) and the N-hydroxamic acid analogue 360C ((E)-N-{3-[3-(4-fluorophenoxy) phenyl]-1-(R, S)-methylprop-2-enyl}-N-hydroxamic acid), were administered to rats. 70C and 360C were dosed to female

The effect of Lyprinol was evaluated on LTB4-induced human monocytes (normal and allergic donors) activation. Peripheral blood normal monocyte-derived monocytes when stimulated by Interleukin-4 (IL-4) produced high amounts of leukotriene B4 (LTB4) through the activation of the 5-lipoxygenase pathway. Maximal

A method has been established for measurement of tracheal secretions in anaesthetized, ventilated guinea-pigs. The upper trachea was cannulated and perfused with saline. The perfusate was analysed for protein using the Lowry assay and for glycoconjugates ('mucus') by a procedure
