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.
