Treatment compositions for neutralizing acidic species and reducing hydrochloride and amine salts in a fluid hydrocarbon stream are disclosed. The treatment compositions may comprise at least one amine with a salt precipitation potential index of equal to or less than about 1.0. Methods for neutralizing acidic species and reducing deposits of hydrochloride and amine salts in a hydrocarbon refining process are also disclosed. The methods may comprise providing a fluid hydrocarbon stream and adding a treatment composition to the fluid hydrocarbon stream. The treatment compositions used may have a salt precipitation potential index of equal to or less than about 1.0 and comprise either water-soluble or oil-soluble amines.

To provide a novel class-A GPCR antagonist, a production method therefor, or a novel compound that interacts with a Na.sup.+-water cluster binding site of a class-A GPCR.

Used is a compound or a salt thereof comprising a structure comprising a class-A GPCR-binding compound linked to a functional group that can bind to a Na.sup.+-water cluster binding site of the class-A GPCR. Also used is a method for producing a class-A GPCR antagonist, comprising the step of linking one compound with another compound that can bind to a Na.sup.+-water cluster binding site of the class-A GPCR.
