Propanoic acid derivatives of the formula: ##STR1## where R.sup.1 is a C.sub.1-8 alkyl group optionally substituted by hydroxyl or --COOH and R.sup.2 is hydrogen or a protecting group, are useful as anti-thrombotic agents.

Cyclopentone propanoic acid compounds

The invention provides 3-(2-formyl-3-hydroxy-5-oxocyclopent-1-enyl)-p ropanoic acid and derivatives thereof having anti-thrombotic activity coupled with low toxicity. Also provided is a method for preparing such compounds by subjecting a 3-[3-hydroxy-5-oxo-2-(.beta.-styryl)cyclopent-1-enyl]-propanoic acid or derivative thereof to oxidative cleavage.

3-Substituted propanoic acid derivatives

Propanoic acid derivatives of formula: ##STR1## where X represents a ketonic or hydroxylic function, R.sup.1 is a C.sub.1.sub.-8 alkyl group optionally substituted by hydroxy or --COOH and R.sup.2 is hydrogen or a protecting group, having spasmolytic activity.

Organic derivatives

The invention provides 3-(2-formyl-3-hydroxy-5-oxocyclopent-1-enyl)-propanoic acid and derivatives thereof having anti-thrombotic activity coupled with low toxicity. Also provided is a method for preparing such compounds by subjecting a 3-[3-hydroxy-5-oxo-2-(.beta.-styryl)cyclopent-1-enyl]-propanoic acid or derivative thereof to oxidative cleavage.
