ix

The invention refers to a novel pharmaceutical composition having especially antimycotic activity and comprising the zinc complex of 5chloro-7-iodo-8-hydroxyquinoline of formula (I) See Patent for Chemical Structure (I) and one or more pharmaceutically acceptable carriers. The pharmaceutical composition of the invention can be used for the effective treatment of mycotic infections on the skin surface, mucous membranes or nails. The complex of formula (I) is prepared by reacting a solution of an alkali metal salt of 5-chloro-7-iodo-8hydroxyquinoline with a solution containing an excess of an inorganic or organic zinc salt or a zinc complex having a lower stability constant than that of the complex of formula (I) and separating the product precipitated.

Stereoisomeric tricyclic bis(dioxopiperazines) of the formula See Patent for Chemical Structure wherein R is H or See Patent for Chemical Structure and the processes for the synthesis thereof are provided. The compounds are effective as antitumor or antimetastatic drugs.

4871772 PROCESS FOR MAKING A STABLE PHARMACEUTICAL PREPARATION OF PROSTAGLADIN E COMPOUNDS, AND/OR 15R FORMS THEREOF Kohtar Miwa, Kazuo Igusa, Toshichika Ogasawara, Tokyo, Japan assigned to Chugai Seiyaku Kabushiki Kaisha A process for making a stable pharmaceutical preparation of prostaglandin E compounds and/or 15R forms thereof is diclosed. Prostagladin E compounds and 15R forms thereof are know to have useful pharmacological actions even if they are used in a vary small amounts. However, they are extremely unstable and, therefore, considerably difficult in application for routine clinical purposes. In order to remove this difficulty, prostagladin E compounds and
