Effects of beta-cyclodextrin and methyl jasmonate on the production of vindoline, catharanthine, and ajmalicine in Catharanthus roseus cambial meristematic cell cultures.[Pubmed:25981997]

Appl Microbiol Biotechnol. 2015 Sep;99(17):7035-45.

Long-term stable cell growth and production of vindoline, catharanthine, and Ajmalicine of cambial meristematic cells (CMCs) from Catharanthus roseus were observed after 2 years of culture. C. roseus CMCs were treated with beta-cyclodextrin (beta-CD) and methyl jasmonate (MeJA) individually or in combination and were cultured both in conventional Erlenmeyer flasks (100, 250, and 500 mL) and in a 5-L stirred hybrid airlift bioreactor. CMCs of C. roseus cultured in the bioreactor showed higher yields of vindoline, catharanthine, and Ajmalicine than those cultured in flasks. CMCs of C. roseus cultured in the bioreactor and treated with 10 mM beta-CD and 150 muM MeJA gave the highest yields of vindoline (7.45 mg/L), catharanthine (1.76 mg/L), and Ajmalicine (58.98 mg/L), concentrations that were 799, 654, and 426 % higher, respectively, than yields of CMCs cultured in 100-mL flasks without elicitors. Quantitative reverse transcription (RT)-PCR showed that beta-CD and MeJA upregulated transcription levels of genes related to the biosynthesis of terpenoid indole alkaloids (TIAs). This is the first study to report that beta-CD induced the generation of NO, which plays an important role in mediating the production of TIAs in C. roseus CMCs. These results suggest that beta-CD and MeJA can enhance the production of TIAs in CMCs of C. roseus, and thus, CMCs of C. roseus have significant potential to be an industrial platform for production of bioactive alkaloids.

Description

Ajmalicine (Raubasine) is found in herbs of Catharanthus roseus, is an antihypertensive drug used in the treatment of high blood pressure, decreases peripheral resistance and blood pressure. Ajmalicine (Raubasine) is an adrenolytic drug which preferentially blocks alpha 1-adrenoceptor than alpha 2-adrenoceptor. Ajmalicine (Raubasine) is an reversible non-competitive nicotine receptor antagonist with an IC50 of 72.3 μM. Ajmalicine (Raubasine) acts preferentially at postsynaptic sites, competitively antagonizes the effect of noradrenaline on postsynaptic alpha-adrenoceptor with a pA2 value of 6.57, blocks the inhibitory effect of clonidine with an pA2 value of 6.2.
