n-formyl-met-leu-phe

N-Formyl-Met-Leu-Phe (N-Formyl-MLF) 是一种趋化肽和N-甲酰基肽受体的特异性配体，可抑制TNF-alpha 的分泌。

N-Formyl-Met-Leu-Phe-Lys (fMLFK) 是一种多肽，是选择性FPR1激动剂，作用于 FPR1(IC50:3.5 nM)，FPR2(IC50:6.7 nM) 和 FPR2-D2817.32G(IC50:0.88 nM) 。

Sydowinin B is a xanthone polyketide that has been found inA. sydowiiand has immunosuppressant activity.1It inhibits LPS- or concanavalin A-induced proliferation of isolated mouse splenic lymphocytes (IC50s = 19.2 and 20.8 μg ml, respectively).2Sydowinin B inhibits superoxide generation in, and elastase release from, isolated human neutrophils induced by cytochalasin B and N-Formyl-Met-Leu-Phe with IC50values of 21.2 and 12.62 μM, respectively.3

8-bromo NAD+ 作为循环ADP-核糖（cADPR）抑制剂8-bromo cADPR的前药形式，通过CD38转化为8-bromo-cADPR。在1 mM浓度下，8-bromo NAD+ 阻止由N-formyl-Met-Leu-Phe (fMLP) 在分离的小鼠骨髓衍生的中性粒细胞内引起的细胞内钙水平增加和趋化作用。同时，在100 µM浓度下使用，减少了小鼠原代小胶质细胞中LPS诱导的亚硝酸盐产生以及TNF-α和IL-2的分泌。

N-Formyl-Met-Ala-Ser is a peptide that binds to formyl peptide receptors on neutrophils. This N-Formylmethionine-containing peptide, known as fMet-Ala-Ser, is among the most potent and well-known peptides that interact with these receptors.
