A compound of the formula ##STR20## wherein R is hydrogen, lower alkyl, lower alkoxy or chloro; or a derivative thereof selected from a lower alkyl ester, a (lower)alkylamino(lower)alkyl ester, a pharmaceutically acceptable (lower)alkylamino(lower)alkyl ester acid-addition salt and a pharmaceutically acceptable carboxylate salt.
Claim 2
Dependent Claim
42 words
A compound of the formula ##STR20## wherein R is hydrogen, lower alkyl, lower alkoxy or chloro; or a derivative thereof selected from a lower alkyl ester, a (lower)alkylamino(lower)alkyl ester, a pharmaceutically acceptable (lower)alkylamino(lower)alkyl ester acid-addition salt and a pharmaceutically acceptable carboxylate salt.
Claim 3
Dependent Claim

Claim 6
Independent Claim
71 words
A method for inhibiting bronchoconstriction due to an allergic reaction in a mammal comprising administering a compound to said mammal in an amount effective to inhibit said bronchoconstriction, said compound being of the formula: ##STR22## wherein R is hydrogen, lower alkyl, lower alkoxy or chloro; or a derivative thereof selected from a lower alkyl ester, a (lower)alkylamino(lower)alkyl ester, a pharmaceutically acceptable (lower)alkylamino(lower)alkyl ester acid-addition salt and a pharmaceutically acceptable carboxylate salt.
Claim 7
Independent Claim
71 words
A method for inhibiting bronchoconstriction due to an allergic reaction in a mammal comprising administering a compound to said mammal in an amount effective to inhibit said bronchoconstriction, said compound being of the formula: ##STR22## wherein R is hydrogen, lower alkyl, lower alkoxy or chloro; or a derivative thereof selected from a lower alkyl ester, a (lower)alkylamino(lower)alkyl ester, a pharmaceutically acceptable (lower)alkylamino(lower)alkyl ester acid-addition salt and a pharmaceutically acceptable carboxylate salt.
Claim 8
Dependent Claim
70 words
An antiallergic pharmaceutical composition comprising an antiallergic compound and a pharmaceutically acceptable carrier, said antiallergic compound being present in an amount sufficient for providing an antiallergic response and being of the following formula: ##STR23## wherein R is hydrogen, lower alkyl, lower alkoxy or chloro; or a derivative thereof selected from a lower alkyl ester, a (lower)alkylamino(lower)alkyl ester, a pharmaceutically acceptable (lower)alkylamino(lower)alkyl ester acid-addition salt and a pharmaceutically acceptable carboxylate salt.
Claim 9
Dependent Claim
70 words
An antiallergic pharmaceutical composition comprising an antiallergic compound and a pharmaceutically acceptable carrier, said antiallergic compound being present in an amount sufficient for providing an antiallergic response and being of the following formula: ##STR23## wherein R is hydrogen, lower alkyl, lower alkoxy or chloro; or a derivative thereof selected from a lower alkyl ester, a (lower)alkylamino(lower)alkyl ester, a pharmaceutically acceptable (lower)alkylamino(lower)alkyl ester acid-addition salt and a pharmaceutically acceptable carboxylate salt.
Claim 10
Independent Claim
67 words
A method for inhibiting leukotriene synthesis in a mammal comprising administering a compound to said mammal in an amount effective to inhibit said synthesis, said compound being of the formula: ##STR24## wherein R is hydrogen, lower alkyl, lower alkoxy or chloro; or a derivative thereof selected from a lower alkyl ester, a (lower)alkylamino(lower)alkyl ester, a pharmaceutically acceptable (lower)alkylamino(lower)alkyl ester acid-addition salt and a pharmaceutically acceptable carboxylate salt.
Claim 11
Independent Claim
67 words
A method for inhibiting leukotriene synthesis in a mammal comprising administering a compound to said mammal in an amount effective to inhibit said synthesis, said compound being of the formula: ##STR24## wherein R is hydrogen, lower alkyl, lower alkoxy or chloro; or a derivative thereof selected from a lower alkyl ester, a (lower)alkylamino(lower)alkyl ester, a pharmaceutically acceptable (lower)alkylamino(lower)alkyl ester acid-addition salt and a pharmaceutically acceptable carboxylate salt.
Claim 12
Independent Claim
