Abstract: A dipeptide derivative as formyl peptide receptor 1 (FPR1) antagonist is provided. The dipeptide derivative is represented by formula (I), wherein: the chiral centers in formula (I) are S and R configurations respectively; each of RK and RT is selected from a group consisting of a hydrogen, a hydroxyl group, a C1-C4 alkyl-substituted hydroxyl group, a C1-C4 alkoxyl group, a carboxylic acid group, a C1-C4 alkyl nitrile-substituted, C1-C4 alkyl-substituted or C1-C4 alkoxyl-substituted amido group, a C1-C4 alkyl-substituted ester group and a benzoyl group having a C1-C4 alkyl-substituted benzene ring; and each of RM and RS is selected from a group consisting of a hydrogen, a hydroxyl group, a phenyl group, a pyridinyl group, a carboxylic acid group, a C1-C4 alkoxyl substituted ester group, and a benzoyl group having a hydroxyl-substituted, a halogen-substituted, a C1-C4 alkoxyl-substituted or a C1-C4 alkyl-substituted benzene ring.

Abstract: Disclosed are 5-nitrobenzoate derivatives of Formula I, and the preparation method therefor, wherein R is referred to hydrogen (H), unsubstituted, mono-substituted, di-substituted or tri-substituted benzoyl moiety. 5-Nitrobenzoare derivatives of Formula I do not affect the platelet aggregation, possesses the inhibitory activity related to the tumor cell-induced platelet aggregation (TCIPA), and further specifically inhibits podoplanin-induced platelet aggregation. Therefore, 5-nitrobenzoates of the invention are applicable in its therapeutic use as the novel therapeutic agent in preventing tumor metastasis.
