The compounds are C.sub.2 -C.sub.8 straight chain alkanes terminally substituted, symmetrically or unsymmetrically, by N-(N'-substituted guanidino), N-(N',N"-disubstituted guanidino), N-(N'-substituted thioureido), N-(nitromethylene amidino) or S-(N-substituted isothioureido)groups. Two compounds of the invention are 1,3-bis-[N'-(2-(3-methoxy-2-pyridylmethylthio)ethyl)guanidino]propane and 1-[N-(2-(3-methoxy-pyridylmethylthio)ethyl)guanidino]-3-[N'-2-(5-methyl-4- imidazolylmethylthio)ethyl)guanidino]propane. The compounds of this invention are inhibitors of H-2 histamine receptors.
