WKYMVM-NH2 TFA 是有效的 N-甲酰肽受体 FPR1 和 FPRL1/2 的激动剂，同时可以激活一些白细胞效应功能，如趋化性、激活补体受体-3 及 NADPH 氧化酶。
WKYMVM-NH2 TFA is a potent N-formyl peptide receptor (FPR1) and FPRL1/2 agonist, also activates several leukocyte effector functions such as chemotaxis, mobilization of complement receptor-3, and activation of the NADPH oxidase[1][2][3].
WKYMVM-NH2 TFA (10-1000 nM; 24 hours) induces Caco-2 cells proliferation[3].
WKYMVM-NH2 TFA (8 mg/kg; six times; for 5 days) ameliorates DSS-induced ulcerative colitis[3].WKYMVM-NH2 TFA affects cytokine (IL-17, IFN-γ, IL-6, IL-1β and TNF-α) profiles in the DSS colitis model[3].
