General Pharmacology of Aspalatone

Aspalatone의 일반약리작용

Aspalatone [3-(2-methyl-4proponyl)]-2-acetyloxybenzoate, CAS 147249-33-0) is a compound having an antithrombotic action. General pharmacological properties of aspalatone were studied. Aspalatone had no effect on central nervous system and no anticonvulsant effect up to 1200 mg/kg p.o. However, the compound has hypothermic and analgesic effect. When administered intravenously in rabbits, aspalatone did not affect blood pressure, heat rate and respiration rate and depth, and it did not inhibit transient hypotensive effect of acetylcholine. The compound did not affect isolated guinea-pig ileum and tracheal strip at a concentration of 1${\times}$$10^{-4}$, and did not inhibit histamine-induced contraction of guinea-pig ileum. It also did not affect isolated rat stomach fundus and estrogenated rat uterus at 1${\times}$$10^{-4}$, and did not inhibit contraction produced by acetylcholine or oxytocin. The pupil size and intestinal propulsion were not influenced at a large dose of was shown. The compound showed a slight increase in urine volume and led to decreased excretion of potassium in urine of rats. The results suggest that aspalatone may have no considerable adverse effects in general pharmacological aspect.
