A set of 2-[4-(dialkylaminoalkoxy)phenyl]benzotriazoles and corresponding N-oxides was prepared. In a preliminary pharmacological investigation concerning some of these compounds, several in vitro and in vivo activities were shown. At concentrations in the range of 3-10 microM all tested compounds strongly inhibited (50-100%) the guinea pig ileum contractions induced either electrically or by means of several agonists; of particular interest was the antagonism to leukotriene D4. Compound 5b inhibited platelet aggregation induced by thromboxane A2, PAF and ADF (but not by arachidonic acid) and increased the bleeding time in mice. Compounds 5b and 6b protected mice from potassium cyanide hypoxia and exerted anti-hypercholesterolemic action; the first compound produced a ratio between HPL and total serum cholesterol concentrations below 0.92, thus indicating a potential anti-atherogenic activity.

D017998 Leukotriene D4 One of the biologically active principles of SRS-A. It is generated from LEUKOTRIENE C4 after partial hydrolysis of the peptide chain, i.e., cleavage of the gamma-glutamyl portion. Its biological actions include stimulation of vascular and nonvascular smooth muscle, and increases in vascular permeability.
