The present invention relates to 7-[carboxyalkyl or alkenyl]-6-[alkyl or alkenyl]-3-oxo-2,4-dioxobicyclo[3.2.1]octanes and derivatives thereof. In particular, hydroxyl, nitro, amino, amido, azido, oxime, thiol, ether and thiol ether derivatives of said carboxy group are contemplated. In particular, 7-[6-carboxy-2-hexenyl]-6-[3-hydroxy-1-octenyl] of 3-oxo-2,4-dioxobicyclo-[3.2.1 ]octane and derivatives thereof are disclosed. These compounds are useful as ocular hypotensives and as (a) thromboxane mimetics for the prevention of hemorrhaging as follows:, during surgery; tooth extraction; hemorrhaging associated with gastro-intestinal diseases and conditions such as hemorrhoids, inflammatory bowel diseases and gastric and peptic ulcers; as a result of stroke; as a complication in retinal diseases resulting in impaired vision and associated with-menstruation, childbirth and uterine dysfunction and (b) selective vasoconstrictors for treating systemic hypotension, e.g. in restoring normal blood pressure in hemorrhagic, anaphylactic, or septic shock victims; to provide local anti-inflammatory effects in the eye, skin and nose; to limit plasma exudation in burns, etc. and optimizing blood born delivery of drugs and diagnostics in encapsulating vehicles.
The method of treating ocular hypertension which comprises applying a sufficient amount of the compound of formula III ##STR5## wherein hatched lines indicate .alpha. configuration, solid triangles are used to indicate .beta. configuration, R.sub.3 is .dbd.O, --OH or --O(CO)--R.sub.6 wherein R.sub.6 is a saturated or unsaturated acyclic hydrocarbon group having from 1 to about 20 carbon atoms, X is --CH.sub.2 SR.sub.4, wherein R.sub.4 is hydrogen, C.sub.1 to C.sub.10 alkyl, phenyl or benzyl;
A pharmaceutical composition for treating ocular hypertension which comprises a therapeutically effective amount of a compound of formula III ##STR6## wherein hatched lines indicate .alpha. configuration, solid triangles are used to indicate .beta. configuration R.sub.3 is .dbd.O, --OH or --O(CO)--R.sub.6 wherein R.sub.6 is a saturated unsaturated acyclic hydrocarbon group having from 1 to about 20 carbon atoms, X is --CH.sub.2 SR.sub.4, wherein R.sub.4 is hydrogen, C.sub.1 to C.sub.10 alkyl, phenyl or benzyl;
A compound of formula III ##STR7## wherein hatched lines indicate .alpha. configuration, solid triangles are used to indicate .beta. configuration R.sub.3 is .dbd.O, --OH or --O(CO)--R.sub.6 wherein R.sub.6 is a saturated or unsaturated acyclic hydrocarbon group having from 1 to about 20 carbon atoms, X is --CH.sub.2 SR.sub.4, wherein R.sub.4 is hydrogen, C.sub.1 to C.sub.10 alkyl, phenyl or benzyl;
