Anthelmintic acylhydrazones, method of use and compositions

This invention concerns a process for killing internal parasites, especially nematodes and cestodes affecting warm blooded animals such as sheep, cattle, swine, goats, dogs, cats, horses and humans as well as poultry by administering an effective amount of a compound of the Formula I: ##STR1## Certain of the compounds of Formula I are novel and in further embodiments of the invention provide novel compounds and compositions for use in the process of the invention. The compounds are readily prepared by conventional chemical reactions. Various pyridinyl acylhydrazones of Formula I demonstrate broad-spectrum anthelmintic activity in sheep upon oral and/or parenteral administration.

Anthelmintic quinolinyl acylhydrazones, method of use and compositions

A method of improving the endogenous production of prostaglandins by a mammal is disclosed which comprises administering to the mammal an effective amount of certain 1-pyridylalkyl-3-phenylthioureas. Disclosed also are novel substituted 1-pyridylalkyl-3-phenylthioureas and therapeutic compositions thereof which are useful in carrying out the method of the invention. Disclosed also are methods of treating mammals for clinical conditions responsive to prostaglandins, such as for example, male infertility, epidermal injuries, atonic uterine bleeding, thromboembolic disease and like clinical conditions.
