Abstract: N,N'-substituted polymethylene diamines of the formula: ##STR1## in which: A is a hydrocarbon radical from C.sub.3 to C.sub.5 in a straight or branched chain optionally containing one and two double bonds and possibly substituted by one or more hydroxy radicals;X is CH or nitrogen;n is an integer from 2 to 6;R.sub.1 is hydrogen, or alkyl from C.sub.1 to C.sub.5 ;R.sub.2 is hydrogen, alkyl from C.sub.1 to C.sub.5, cycloalkyl from C.sub.5 to C.sub.7, or phenyl optionally substituted by one or more fluorine or chlorine, andB is:phenyl, naphthyl, benzofuranyl, benzothionyl, benzodioxolyl, benzodioxanyl, benzodioxinyl, .DELTA.3-chromenyl, thiochromenyl or chromanyl, each of them optionally substituted by fluorine, chlorine, alkyl or alkoxy from C.sub.1 to C.sub.5, or methylene-dioxy, ora radical of the formula: ##STR2## in which R.sub.3, R.sub.4 and R.sub.5 which may be the same or different, each represent hydrogen or phenyl optionally substituted by fluorine or chlorine.

Abstract: Piperidylbenzimidazolinone derivatives of the formula: ##STR1## in which: R.sub.1 is lower alkyl, phenyl, halophenyl, lower alkylphenyl, lower alkoxyphenyl, methylenedioxyphenyl, ethylenedioxyphenyl, thienyl, furyl or pyridyl.R.sub.2 is R'.sub.1 COO-- or R'.sub.1 --COO--CH.sub.2 -- in which R'.sub.1 has the same meanings as R.sub.1, R.sub.1 and R'.sub.1 being the same or different, or R.sub.3 NH-- in which R.sub.3 is formyl, acetyl mesyl, carbamoyl, sulfamoyl or ethoxalyl.Z is hydrogen, lower-alkyl or lower alkenyl, andT is hydrogen, lower alkyl or lower alkoxy.These compounds and physiologically tolerable acid addition salts thereof may be used as medicines especially in the treatment of autoimmune, allergic and antiinflammatory diseases and in the treatment of dyspnea especially asthmatic and bronchial dyspnea.

Abstract: Piperidylbenzimidazolinone compounds of the formula: ##STR1## in which: R is hydrogen, hydroxy, hydroxymethyl, methoxycarbonyl, formamido, acetamido, mesylamino, oxalamino, ethoxalylamino, carbamoyl ##STR2## ureido ##STR3## or sulfamoylamino ##STR4## in which R' and R" are hydrogen or lower alkyl, T is hydrogen, halogen, lower alkyl or lower alkoxy, andZ is hydrogen, lower alkyl or lower alkenyl each in straight or branched chain.These compounds and physiologically tolerable acid addition salts thereof may be used as medicines especially in the treatment of autoimmune, allergic and inflammatory diseases and in the treatment of respiratory insufficiency of asthma.
