Analgesic and Psychotropic Effects of a New Bradykinin Antagonist.

A bradykinin B receptors antagonist PAV-0056, an 1,4-benzodiazepin-2-one derivative, intragastrically administrated to mice at doses of 0.1 and 1 mg/kg causes analgesia in the "formalin test" not inferior to that of diclofenac sodium (10 mg/kg) and tramadol (20 mg/kg). PAV-0056 at doses of 0.

Pharmacological Effects of a New Soluble Guanylate Cyclase Stimulator in Experimental Ischemic Stroke.

We studied the action of a new indolinone derivative GRS, acetylsalicylic acid (ASA), and their combination on platelet aggregation, vasodilatory endothelial function, neurological status, and cerebral infarction area in experimental focal cerebral ischemia/reperfusion in rats. GRS compound (10 mg/kg), ASA (10 mg/kg), and their combination in the same doses were administered orally once a day as a suspension in 1% starch solution over 5 days after pathology modeling. Sham-operated and control animals were administered 1% starch solution.

Pharmacological Effects of a New Indolinone Derivative in Experimental Pneumonitis in Rats.

We studied the effect of a new indolinone derivative GRS on animal survival and on functioning and histological structure of the lungs in rats with experimental pneumonitis. The rats of experimental groups were intratracheally administered 0.5% aqueous solution of carrageenan under intramuscular anesthesia.

Anti-Atherosclerotic Action of a New Stimulator of Soluble Guanylate Cyclase in an Experiment.

We studied the effect of an indolinone derivative GRS on the development of experimental atherosclerosis in C57BL/6 mice. Atherosclerosis was modeled by intraperitoneal administration of endothelial lipoprotein lipase inhibitor Kolliphor P 407 micro Geismar over 5 months. GRS was administered orally in a dose of 10 mg/kg once a day throughout the experiment.

Effects of a New Antithrombotic Drug GRS, a Soluble Guanylate Cyclase Stimulator, on Endothelial Dysfunction in Rats with Myocardial Infarction.

New antithrombotic drug GRS, a soluble guanylate cyclase stimulator, after repeated administration in a dose of 10 mg/kg alleviates the symptoms of endothelial dysfunction in rats with myocardial infarction; it restores antiplatelet activity of the blood vessel wall and vasodilatory function of the endothelium without producing significant effect on endothelium-independent vasodilation. GRS also has direct antiaggregant and antihypertensive effects in therapeutic doses. The obtained data suggest that GRS can be therapeutically useful in patients with cardiovascular diseases accompanied by endothelial dysfunction.
