Abstract

The invention discloses a phenyl acrylic acid farnesyl thiosalicylic acid (FTA) derivative as well as a preparation method and an application. The phenyl acrylic acid farnesyl thiosalicylic acid derivative is a compound of a formula (I) in the specification, wherein X1 represents O or NH; X2 represents O or NH; n is equal to 1- 3; R represents H or OCH3. By coupling ferulic acid and p-hydroxy cinnamic acid fragments with carboxyl of FTA, the capability of a target molecule in scavenging free radicals is improved, the anti-tumor effect of the molecule is improved, and then a compound with anti-tumor activity or anti-inflammatory activity higher than those of FTA is obtained.

Description

technical field [0001] The invention relates to the field of biomedicine, in particular to novel farnesylthiosalicylic acid derivatives of phenylacrylic acid and pharmaceutically acceptable salts thereof, their preparation methods, pharmaceutical compositions containing these derivatives and their Medical use, especially in the preparation of anti-tumor drugs and anti-inflammatory response drugs. Background technique [0002] All-trans farnesyl thiosalicylic acid (abbreviation: FTA, trade name: Salirasib) is the first farnesyl-based Ras protein inhibitor, which can competitively replace F-Ras and F-Ras muteins with half Lectin binds and inhibits Ras-induced downstream signaling pathways (including Raf and P13K signaling pathways) and mTOR (a stimulator of tumorigenesis, which can rely on or independently open P13K signaling pathways), thereby promoting tumor cell apoptosis and inhibiting tumors cell growth. Studies have shown that FTA has inhibitory effects on breast cance...
