Abstract: There are described compounds of the formula ##STR1## where n is 0 or 1;X is hydrogen, loweralkyl, loweralkoxy, halogen, formyl, loweralkylcarbonyl, loweralkyoxycarbonyl, loweralkoxycarbonylloweralkyl or hydroxymethyl;Y is hydrogen or halogen;andR is hydrogen, loweralkyl arylloweralkyl or loweralkylcarbonyl,which compounds are useful as topical antiinflammatory agents for the treatment of various dermatoses.

Abstract: This invention relates to aminoalkylphenoxyalkyl substituted heterocycles. These compounds antagonize the action of histamine on histamine H.sub.2 -receptors in the brain. A compound of the invention is 2-[3-[3-(piperidinomethyl)phenoxy]propylamino]benzthiazole.

Abstract: Novel carbamates of 2-ureado-6-hydroxy-pyridines have the structural formula ##STR1## wherein n is 0 to 20; R.sub.1 is hydrogen, alkyl which may be substituted, aryl which may be substituted; R.sub.2 is hydrogen, halogen, carboxylic, SO.sub.3 H, NO.sub.2, alkyl or aryl; R.sub.3 and R.sub.4 have the same meaning as R.sub.2 ; Z is N.dbd.C.dbd.O, N.dbd.C.dbd.S, carboxylic, primary or secondary amine and when n.dbd.O, Z may be ##STR2## wherein Q is hydroxyl, amino, carboxylic, sulfhydryl, isocyanato or isothiocyanato. The carbamates of 2-ureado-6-hydroxypyridines react with compounds of interest to form derivatives which will chelate metal ions such as radionuclides or lanthanides, resulting in the radioisotopic or fluorescent labeling of the compounds.

Abstract: Substituted N-cyanomethyl-2-pyridinones were prepared by the reaction of alkali metal substituted-2-pyridinates with monohaloacetonitriles and found to possess insecticidal properties. The alkali metal substituted-2-pyridinates can be preformed or prepared from the corresponding 2-halopyridines or 2-pyridinols in the reaction medium. N-cyanomethyl-3-fluoro-5-(trifluoromethyl)-2-pyridinone, for example, was prepared from 2,3-difluoro-5-(trifluoromethyl)pyridine and found to control aster leafhoppers both on contact and systemically.
