Method of treating coccidiosis with acyl guanidines

A class of bicyclic nitrogen heterocyclic ether and thioether compounds exhibiting pharmacological activity including anti-secretory and anti-ulcerogenic activity, pharmaceutical compositions comprising these compounds, and methods for the treatment of gastrointestinal hyperacidity and ulcerogenic disorders in mammals using said compositions are disclosed.

Novel s-triazine compounds are prepared as derivatives of the corresponding amidinourea and amidinothiourea compounds by reacting with an activated form of an acid amide to give substituted s-triazinones and thiones respectively, of the formula ##STR1## The s-triazinones and thiones are useful derivatives in analyzing for the corresponding amidinourea or amidino thiourea precursors and also have useful pharmacological properties which make them suitable for a variety of medicinal purposes including use as antidiarrheal agents.

Triazinones

This invention relates to a novel class of amidinourea and amidinothiourea compounds wherein the urea nitrogen atom is substituted by a heterocyclic alkylene group, and their use in pharmaceutical preparations which are useful for producing anti-ulcerogenic, antisecretory, antispasmodic, antihypertensive, anesthetic, anti-arrhythmic, antidiarrheal and antiparasitic action.

Pyridyl alkylene amidinoureas

A new class of chemical compounds and their process of preparation is described. These compounds have valuable properties as anti-secretory, anti-spasmodic, anti-ulcerogenic and anti-diarrheal agents.

Amidinoureas

This invention describes a new class of 1-amidino-3-phenylthiourea and N'-phenylamidinothiourea compounds wherein the phenyl group is ortho substituted, and processes for their preparation. The phenylamidinothiourea compounds may be incorporated into pharmaceutical preparations which are useful for producing anti-ulcerogenic, antisecretory, antispasmodic, antihypertensive, anti-arrhythmic, anesthetic, antidiarrheal and antiparasitic action.

Amidinothioureas

Heterocyclic alkyl s-triazine compounds are prepared from the corresponding amidinourea and amidinothiourea compounds by reacting with an activated form of an acid amide to give respectively substituted s-triazinones and thiones of the formula ##STR1## which have pharmacological properties that render them suitable for use for a variety of medicinal purposes, including use as antidiarrheal agents, and which are also useful derivatives in analyzing for the corresponding amidinourea or amidinothiourea precursors.
