Claims
- 1. A carboxamide compound of the formula ##STR44## or a pharmaceutically-acceptable salt thereof; wherein R.sup.1 is selected from the group consisting of hydrogen, alkyl having 1 to 4 carbons and --CH.sub.2 --CH.sub.2 --NR.sup.3 R.sup.4, wherein R.sup.3 and R.sup.4 are each alkyl having 1 to 3 carbons;
- and R.sup.2 is selected from the group consisting of alkyl having 8 to 15 carbons and cycloalkyl having from 6 to 12 carbons;
- with the proviso that the two groups attached to the ##STR45## have a trans relationship to each other.
- 2. A compound according to claim 1, wherein R.sup.1 is hydrogen.
- 3. A compound according to claim 2, wherein R.sup.2 is said alkyl.
- 4. A compound according to claim 3, wherein the two substituents on the phenyl ring have a para relationship to each other.
- 5. A compound according to claim 4, wherein R.sup.2 is octyl.
- 6. A compound according to claim 4, wherein R.sup.2 is decyl.
- 7. A compound according to claim 4, wherein R.sup.2 is 1-methyldecyl.
- 8. A method for antagonizing the effect of the slow-reacting substance of anaphylaxis in a human subject, which comprises administering to said human subject a slow-reacting substance of anaphylaxis antagonizing amount of a carboxamide compound of the formula ##STR46## or a pharmaceutically-acceptable salt thereof; wherein R.sup.1 is selected from the group consisting of hydrogen, alkyl having 1 to 4 carbons and --CH.sub.2 --CH.sub.2 --NR.sup.3 R.sup.4, wherein R.sup.3 and R.sup.4 are each alkyl having 1 to 3 carbons;
- and R.sup.2 is selected from the group consisting of alkyl having 8 to 15 carbons and cycloalkyl having from 6 to 12 carbons;
- with the proviso that the two groups attached to the ##STR47## have a trans relationship to each other.
- 9. The method according to claim 8, wherein R.sup.1 is hydrogen.
- 10. The method according to claim 9, wherein R.sup.2 is said alkyl.
- 11. The method according to claim 10, wherein the two substituents on the phenyl ring have a para relationship to each other.
- 12. The method according to claim 11, wherein R.sup.2 is octyl.
- 13. The method according to claim 11, wherein R.sup.2 is decyl.
- 14. The method according to claim 11, wherein R.sup.2 is 1-methyldecyl.
- 15. A pharmaceutical composition useful for antiagonizing the spasmogenic activity of the slow-reacting substance of anaphylaxis which comprises a pharmaceutically-acceptable carrier and an effective amount of a carboxamide compound of the formula ##STR48## or a pharmaceutically-acceptable salt thereof; wherein R.sup.1 is selected from the group consisting of hydrogen, alkyl having 1 to 4 carbons and --CH.sub.2 --CH.sub.2 --NR.sup.3 R.sup.4, wherein R.sup.3 and R.sup.4 are each alkyl having 1 to 3 carbons;
- and R.sup.2 is selected from the group consisting of alkyl having 8 to 15 carbons and cycloalkyl having from 6 to 12 carbons;
- with the proviso that the two groups attached to the ##STR49## have a trans relationship to each other; and wherein the ratio of the pharmaceutically-acceptable carrier to the carboxamide compounds is in the range from 1:6 to 6:1 by weight.
