Antitussive effect of RU-20201--central and peripheral actions.

The antitussive effect of the new compound 1, 2, 3, 4a, 9b-hexahydro-8, 9b-dimethyl-4-[3-(4-methyl-piperazine-1-yl) propionamide] dibenzofuran-3-one dihydrochloride (RU-20201) was investigated in dogs and guinea pigs, including its sites of action. The antitussive effect of RU-20201 was about 1/10 as potent as that of codeine phosphate in dogs with the puncture electrode-induced cough (PEC) met...

Definition. A binary operation * on a non-empty set S is a rule that assigns to each ordered pair of elements of elements of S a uniquely determined element of S. The element assigned to the ordered pair (a, b) with a, b ∈ S is denoted by a * b. Remark. In other words, a binary operarion of a set S is a function * : S×S → S from the Cartesian product S × S to the set S. The only difference is t...
