2. Description of the Related Art Tachykinin (substance P, neurokinin A, neurokinin B) is a general term for neuropeptides and their respective receptors (neurokinin 1 (NK ₁ ), neurokinin 2 (NK) ₂ ) It is known that various physiological activities are expressed by binding to neurokinin 3 (NK ₃ )). Among them, substance P acts as a transmitter of central and peripheral primary sensory neurons, and has physiological functions such as a diuretic enhancing action, a nerve cell excitatory action, a vascular permeability enhancing action, a vasodilatory action, a smooth muscle contracting action, and an immune action. It has activity and is considered to be deeply involved in various disease states (frequent urination, urinary incontinence, vomiting, inflammation, allergy, airway disease, pain, central nervous system disease, etc.).
