摘要:
Substituted N-phenyl and N-benzyl abietamide derivatives, including the dehydro-, dihydro-, and tetrahydroabietamide derivatives, are cholesterol lowering agents. The abietamide derivatives, of which N-(2,6-dimethylphenyl)-.DELTA..sup.8 -dihydroabietamide is a typical example, are produced by the reaction of abietic acid, dehydroabietic acid, dihydroabietic acid, tetrahydroabietic acid and/or active derivatives thereof with a substituted aniline or benzylamine.
摘要:
A process for the preparation of amide derivatives of abietic acid, dehydroabietic acid, dihydroabietic acid or tetrahydroabietic acid which comprises reacting abietic acid, dehydroabietic acid, dihydroabietic acid or tetrahydroabietic acid or a reactive derivative thereof with an amine of the following formula:HNRR'wherein R and R' are each hydrogen, a straight chain or branched alkyl group having 3 to 15 carbon atoms, a lower alkenyl group, a cycloalkyl group, a phenyl group, a phenylalkyl group and a phenylalkyl group having a lower alkyl group at the .alpha.-position, with the proviso that such amines where both R and R' are hydrogen or where one of R and R' is hydrogen and the other is phenyl are excluded.The invention further comprises the resulting abietamide derivative reaction products, compositions containing effective blood serum cholesterol-reducing amounts of said abietamide derivatives and their use as anti-arteriosclerotic agents.
摘要:
Process for the preparation of abietanilides which comprises reacting abietic acid, dihydroabietic acid, tetrahydroabietic acid or a reactive derivative thereof with aniline and the products thereby produced, compositions containing the same for reducing blood serum cholesterol and method of use of such compositions.
摘要:
The mono-, bis- and trisnicotinoyl derivatives of melamine and the corresponding mono- and bisnicotinoyl derivatives of benzoguanamine demonstrate anti-ulcer and diuretic activity. A representative embodiment is 2-nicotinamido-4,6-diamino-s-triazine.
