Evocarpine 是从Evodiae fructus分离得到的一种喹诺酮类生物碱，有抗细菌活性。它可通过电压依赖性钙通道抑制 Ca2+内流。

Evocarpine shows antimycobacterial, and vasorelaxant effects, it can inhibit Ca2+ influx through voltage-dependent calcium channels.

The antimycobacterial and modulating activity of evodiamine (1), rutaecarpine (2) and Evocarpine (3) was tested on mycobacteria including three multidrug-resistant (MDR) clinical isolates of Mycobacterium tuberculosis. Antagonistic effects were concluded from fractional inhibitory concentration (FICI) values. Interaction energies of the compounds were calculated using GLUE docking module implemented in GRID. 1 and 2 exhibited weak inhibition of rapidly growing mycobacteria, however, 1 was active against Myco. tuberculosis H37Rv (MIC = 10 mg l(-1) ) while 2 was inactive. Both 1 and 2 showed a marked antagonistic effect on the susceptibility of different mycobacterial strains to 3 giving FICI values between 5 and 9. The interaction energies between compounds 1 and 2 with compound 3 suggested the possibility of complex formation in solution[1]
