    摘要: Novel 3,2'-spiro(1',3'-thiazolidine) compounds which are transient prodrug forms of known 6- and/or 9-haloglucocorticosteroids are described. The subject prodrugs provide improved delivery of the prior art steroids for therapeutic purposes, particularly in alleviating inflammation, and can be prepared by known methods, for example, by reacting the corresponding 3-keto steroids with a thiazolidine forming reagent such as an L-cysteine alkyl ester.

Upon administration to warm-blooded animals, these compounds pass through the gastrointestinal tract and "cleave" in the bloodstream, thus releasing phenylbutazone or oxyphenbutazone in an anti-inflammatory effective amount at their therapeutic site or sites of activity.
