reported tyrosol sinapate (4) as a c-Met inhibitor hit. This study reports additional semisynthetic optimization and SAR of 4 to improve its selective activity against c-Met-dependent breast cancer by increasing its capacity to inhibit c-Met phosphorylation. Forty-three compounds (5-47) were synthesized, among which the novel analog homovanillyl sinapate (HVS-16) was distinguished for its remarkable activity
Synthesis of Amide and Ester Derivatives of Cinnamic Acid and Its Analogs: Evaluation of Their Free Radical Scavenging and Monoamine Oxidase and Cholinesterase Inhibitory Activities
and selective MAO-B inhibitory activity. Compound 20 was the most potent inhibitor of MAO-B. Compounds 18 and 21 showed moderate BChE inhibitory activity. In addition, compound 18 showed potent antioxidant activity and MAO-B inhibitory activity. In a comparison of the cinnamic acid amides and esters, the amides exhibited more potent DPPH free radicalscavengingactivity, while the esters showed stronger

p-coumaroyl tyrosol and CAPE, were also synthesized from glucose using engineered E. coli by introducing genes for the synthesis of substrates. Consequently, we synthesized approximately 393.4 mg/L p-coumaroyl tyrosol and 23.8 mg/L CAPE with this approach. Overall, these findings demonstrate that the rice PMT and 4CL proteins can be used for the synthesis of diverse hydroxycinnamoyl phenylethanoid esters owing
咖啡酸苯乙基酯(CAPE)是羟基肉桂酸(苯基丙烷)和苯基乙醛类化合物(2-苯基乙醇; 2-PE)的酯,长期以来一直在传统医学中使用。在这里,我们通过将64种羟基肉桂酸和苯基乙醇的组合物喂入带有水稻基因OsPMT和Os4CL的大肠杆菌中,从而合成了54种羟基肉桂酸-苯乙醛酸酯。将相同的方法应用于咖啡酸和八种不同的苯醇的酯合成。还使用工程化的大肠杆菌从葡萄糖合成了两种羟基肉桂酰基苯乙基酯,对香豆酰基酪醇和CAPE 。通过引入用于合成底物的基因。因此,通过这种方法,我们合成了约393.4 mg / L对-香豆酰基酪醇和23.8 mg / L CAPE。总体而言,这些发现表明,大米的PMT和4CL蛋白由于其混杂性而可用于合成各种羟基肉桂酰基苯基乙醛酸酯,因此有必要进一步探索这些化合物的生物学活性。
