Influence of aspirin, molsidomine, trapidil, and some trapidil derivatives on arachidonic acid induced reversible thrombocyte aggregation in the rabbit. 1984

U Zehl, and H J Mest, and W Förster

For testing antiaggregatory activity of substances in vivo we used transient decrease of circulating platelet number in rabbit blood after rapid i. v. injection of arachidonic acid (AA) as sign of increased thrombocyte aggregates within the tissues. We tested aspirin, molsidomine, trapidil, and 6 trapidil derivatives. Antiaggregatory effects of aspirin, molsidomine, and trapidil confirm former reports and reliability of the used model. 4 trapidil derivatives were effective in doses lower than trapidil itself.

D010069	Oxadiazoles	Compounds containing five-membered heteroaromatic rings containing two carbons, two nitrogens, and one oxygen atom which exist in various regioisomeric forms.	Oxadiazole
D010974	Platelet Aggregation	The attachment of PLATELETS to one another. This clumping together can be induced by a number of agents (e.g., THROMBIN; COLLAGEN) and is part of the mechanism leading to the formation of a THROMBUS.	Aggregation, Platelet
D011743	Pyrimidines	A family of 6-membered heterocyclic compounds occurring in nature in a wide variety of forms. They include several nucleic acid constituents (CYTOSINE; THYMINE; and URACIL) and form the basic structure of the barbiturates.
D011817	Rabbits	A burrowing plant-eating mammal with hind limbs that are longer than its fore limbs. It belongs to the family Leporidae of the order Lagomorpha, and in contrast to hares, possesses 22 instead of 24 pairs of chromosomes.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D001241	Aspirin	The prototypical analgesic used in the treatment of mild to moderate pain. It has anti-inflammatory and antipyretic properties and acts as an inhibitor of cyclooxygenase which results in the inhibition of the biosynthesis of prostaglandins. Aspirin also inhibits platelet aggregation and is used in the prevention of arterial and venous thrombosis.

D013329	Structure-Activity Relationship	The relationship between the chemical structure of a compound and its biological or pharmacological activity. Compounds are often classed together because they have structural characteristics in common including shape, size, stereochemical arrangement, and distribution of functional groups.
