Described are compounds of the formula ##STR1## wherein R.sup.1 and R.sup.2 are hydrogen, alkyl, cycloalkyl, and aryl, R.sup.3 is hydrogen or halogen, and R.sup.4 is hydrogen or acyl, and pharmaceutically acceptable acid addition salts thereof. R.sup.3 can be located in the 4 or 5 position as can the amino imidazoline group. The compounds are useful as anti-inflammatory agents.
Described is a method of treating hypertensive by administering to mammalian patients compounds of the formula ##STR1## wherein R.sub.1 and R.sub.2 are hydrogen, loweralkyl, lowercycloalkyl, aralkyl, aryl, pyridyl, isoquinolyl, phthalazinyl, or aryl substituted by one or more hydrogen, halo, loweralkyl, lowercycloalkyl, haloloweralkyl, haloloweralkyl, aminosulfonyl, nitro, hydroxy, alkoxy, carboxy, alkoxycarbonyl, cycloalkoxy carbonyl, aminocarbonyl, diloweralkylaminocarbonyl or ##STR2## wherein n is 4 or 5. R.sub.3 is hydrogen, halogen, loweralkyl or aryl, and R.sub.4 is hydrogen, acyl, amino or loweralkyl, and the pharmaceutically acceptable acid addition salts thereof.
Novel aromatic heterocyclic compounds inhibit cytokines production involved in immunoregulation and inflammation such as interleukin-1 and tumor necrosis factor production. The compounds are therefore useful in pharmaceutic compositions for treating diseases or pathological conditions involving inflammation such as chronic inflammatory diseases.
Described is a method of increasing urinary excretion by administering effective amounts to a subject in need thereof of compounds of the formula ##STR1## wherein R.sub.1 and R.sub.2 are hydrogen, loweralkyl, lowercycloalkyl, aralkyl, aryl, pyridyl, isoquinolyl or phthalazinyl, or aryl substituted by one or more hydrogen, halo, loweralkyl, lowercycloalkyl, haloloweralkyl, aminosulfonyl, nitro, hydroxy, alkoxy, carboxy, alkoxycarbonyl, cycloalkoxy carbonyl, aminocarbonyl, diloweralkylaminocarbonyl or ##STR2## wherein n is 4 or 5. R.sub.3 is hydrogen, halogen, loweralkyl or aryl, and R.sub.4 is hydrogen, acyl, amino or loweralkyl, and the pharmaceutically acceptable acid addition salts thereof.
