|Title:||Non-acidic cyclopentane heptanoic acid, 2-cycloalkyl or arylalkyl derivatives as therapeutic agents|
|Abstract:||The present invention provides cyclopentane heptanoic acid, 2-cycloalkyl or arylalkyl derivatives, substituted in the 1-position with halo, methyl, hydroxyl, nitro, amino, amido, azido, oxime, cyano, thiol, either or thioether groups, e.g., a 1-OH cyclopentane heptanoic acid, 2-(cycloalkyl or arylalkyl) derivatives. The cyclopentane heptanoic acid, 2-(cycloalkyl or arylalkyl) derivatives of the present invention are potent ocular hypotensives, and are particularly suitable for the management of glaucoma. Moreover, the cyclopentane heptanoic, 2-(cycloalkyl or arylalkyl) derivatives of this invention are smooth muscle relaxants with broad application in systemic hypertensive and pulmonary diseases; smooth muscle relaxants with application in gastrointestinal disease, reproduction, fertility, incontinence, shock, etc.|

|Claims:||1. A method of treating ocular hypertension which comprises applying to the eye an amount sufficient to treat ocular hypertension of a compound of formula I ##STR11## wherein the dashed bonds represent a single or double bond which can be in the cis or trans configuration, A is an alkylene or alkenylene radical having from two to six carbon atoms, which radical may substituted with one or more hydroxy, oxo, alkyloxy or akylcarboxy groups, B is a cycloalkyl radical having from three to seven carbon atoms, or an aryl radical, selected from the group consisting of phenyl, thienyl, furanyl and pyridyl; |
X is a radical selected from the group consisting of amino, radicals; one of R.sub.1 and R.sub.2 is .dbd.O,--OH or a --O(CO)R.sub.6 group, and the other one is --OH or --O(CO)R.sub.6, or R.sub.1 is .dbd.O and R.sub.2 is H, wherein R.sub.6 is a saturated or unsaturated acyclic hydrocarbon group having from 1 to about 20 carbon atoms, or --(CH.sub.2)m R.sub.7 wherein m is 0-10, and R.sub.7 is cycloalkyl radical, having from three to seven carbon atoms, or an aryl radical, as defined above, or a pharmaceutically-acceptable salt thereof.
2.
