An aerobic photoepoxidation of α,β-unsaturated ketones driven by visible light in the presence of tetramethylguanidine (3b), tetraphenylporphine (H2TPP), and molecular oxygen under mild conditions was revealed. The corresponding α,β-epoxy ketones were obtained in yields of up to 94% in 96 h. The reaction time was shortened to 4.6 h by flow synthesis. The mechanism related to singlet oxygen was supported by experiments and density functional theory (DFT) calculations.

The discovery and optimization of a series of tetrahydropyridopyrimidine based extracellular signal-regulated kinase (Erks) inhibitors discovered via HTS and structure based drug design is reported. The compounds demonstrate potent and selective inhibition of Erk2 and knockdown of phospho-RSK levels in HepG2 cells and tumor xenografts.

A series of novel Ligustrazinyl acylguanidines was designed, synthesized and evaluated for their protective effect on injured vascular endothelial cell (ECV-304). The preliminary results demonstrated that some compounds possessed more potent activities than that of Ligustrazine in stimulating replication of the injured endothelial cell. Among the active compounds, compounds 8b, 8f and 8l displayed remarkable antioxidative activity with low EC50 values of 0.097, 0.059 and 0.094 mM, respectively. Structure-activity relationships were briefly discussed.
