This invention relates to compounds of the formula:
and the pharmaceutically acceptable salts thereof:
wherein R¹ represents straight or branched chain alkyl having 2-4 carbon atoms;
wherein R² represents hydrogen or straight or branched chain alkyl having 1-6 carbon atoms;
wherein R³ represents hydrogen or straight or branched chain alkyl having 1-3 carbon atoms;
wherein R⁴ and R¹⁰ are different and represent H or n-propyl;
wherein X represents an interger from 2 to 5;
wherein R⁵ is hydrogen, or acts with R⁷ to produce an additional carbon-carbon bond between C₁ and C₂;
wherein R⁶ represents hydrogen or -Z-COOR⁹, wherein Z is either absent or represents straight or branched chain alkyl or alkenyl having 1-5 carbon atoms; and R⁹ represents hydrogen, pharmaceutically acceptable cations, or straight or branched chain alkyl having 1-6 carbon atoms;
wherein R⁷ is hydrogen, or acts together with R⁵ to form an additional carbon-carbon bond between C₁ and C₂, or acts together with R⁸ to form
when R⁸ is oxygen;
wherein R⁸ is hydrogen, -O-R¹¹, or oxygen, such that when R⁸ is oxygen, R⁸ acts together with R⁷ to form
and
wherein R¹¹ is straight or branched chain alkyl having 1-4 carbon atoms. The di- and tetrahydronaphthyl compounds of this invention are pharmacologically active as leukotriene D₄ (LTD₄) antagonists and are useful as anti-inflammatory and anti-allergy agents.
