Description
Summary:A new alkaloid (orychophragvioline A) and nine known compounds were yielded from the seeds of <i>Orychophragmus violaceus</i>. Their structures were determined by various spectroscopic techniques and single-crystal X-ray diffraction. Orychophragvioline A is a rare alkaloid with an unusual 1-methyl-4-phenyl-2,3-diketopiperazine skeleton connected with a guanidine group via an amide bond. The results of antitumor tests in vitro showed that it exhibited prominent cytotoxicity against Hela cells with an IC<sub>50</sub> value of 11.95 ± 1.52 μM. Further investigations suggested that it significantly inhibited cellular proliferation, migration, and invasion in a dose-dependent manner, thus inducing the apoptosis of Hela cells. These findings indicate that orychophragvioline A can be regarded as a potential natural leading compound against cervical cancer.
