A series of novel Ligustrazinyl amides was designed, synthesized and evaluated for their protective effect on the injured vascular endothelial cells. The preliminary results demonstrated that some compounds possessed more potent activities than that of Ligustrazine in stimulating replication of the injured human umbilical vascular endothelial cells (HUVECs) that is damaged by hydrogen peroxide.

Bivalent and polyvalent inhibitors can be used as antitumor agents. In this experiment, eight ligustrazine dimers and seven ligustrazine tetramers linked by alkane diamine with different lengths of carbon chain lengths were synthesized. After screening their antiproliferation activities against five cancer cell lines, most ligustrazine derivatives showed better cytotoxicity than the ligustrazine monomer

formation of a co-crystal driven by either C–I···N or C–I···O halogen bonds. The bromo-compound analogues displayed a 60% success rate whereas the chloro-analogues did not yield any co-crystals, emphasizing the importance of the magnitude of the electrostatic aspects of halogenbonding for practical supramolecular synthesis. Ten newcrystalstructures are presented and the outcome (in terms of stoichiometry
tumor cell apoptosis in various cancercelllines, had previously been reported. Moreover, reports have revealed that the introduction of amino acid to betulinic acid could improve selectivecytotoxicity as well as water solubility. Thus, a series of novel TBA amino acid and dipeptide derivatives were designed, synthesized and screened for selectivecytotoxic activity against five cancercell lines
