ABSTRACT:
A method of treating ocular hypotension, hypertension, hemorrhage, myocardial ischemia, angina pectoris, coronary contraction, cerebrovascular contraction after subarachnoidal hemorrhage, cerebral hemorrhage and asthma which comprises administering to a mammal suffering therefrom a therapeutically effective amount of a thromboxane ligand which is a compound formula I,wherein Y is (CH2)x; Z is selected from the group consisting ofand (CR2)x, x is an integer of 1 or 2; n is 0 or 1; R2is hydrogen or an alkyl radical of from 1 to 4 carbons; A is an alkylene or alkenylene radical having from two to seven carbon atoms, which radical may be substituted with one or more hydroxy, oxo, alkyloxy or alkylcarboxy groups or said alkylene or alkenylene may have one or more enchained oxa or imino radicals; B is a methyl radical or a cycloalkyl radical having from three to seven carbon atoms, or an aryl radical, selected from the group consisting of hydrocarbyl aryl and heteroaryl radicals wherein the heteroatom is selected from the group consisting of nitrogen, oxygen and sulfur atoms, or substituted derivatives of said methyl, cycloalkyl or aryl radicals wherein said substituent is selected from the group consisting of halo, nitro, amino, thiol, hydroxy, alkyloxy and alkylcarboxy; and X is selected from the group consisting of nitro, cyano, —COOR, —CH2OR1, —C(O)N(R1)2, —CH2N(R1)2—CH═N—OH and —CH2SR1radicals wherein R is a C1to C10alkyl, phenyl or benzyl and R1is R or hydrogen; or a pharmaceutically acceptable salt thereof.
