spantide II Usage And Synthesis
Uses
Spantide II, an undecapeptide substance P (SP) analog, is a potent neurokinin-1 receptor (NK-1R) antagonist. Spantide II binds with NK-1R and blocks proinflammatory activities associated with SP. Spantide II can be used in the research of inflammatory skin disorders, such as psoriasis and contact dermatitis[1][2][3].
