Appl Microbiol Biotechnol 2024; 108:382. [PMID: 38896329 PMCID: PMC11186875 DOI: 10.1007/s00253-024-13187-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2024] [Revised: 05/14/2024] [Accepted: 05/15/2024] [Indexed: 06/21/2024]
Abstract
Camptothecin (CPT), an indole alkaloid popular for its anticancer property, is considered the third most promising drug after taxol and famous alkaloids from Vinca for the treatment of cancer in humans. Camptothecin was first identified in Camptotheca acuminata followed by several other plant species and endophytic fungi. Increased harvesting driven by rising global demand is depleting the availability of elite plant genotypes, such as Camptotheca acuminata and Nothapodytes nimmoniana, crucial for producing alkaloids used in treating diseases like cancer. Conservation of these genotypes for the future is imperative. Therefore, research on different plant tissue culture techniques such as cell suspension culture, hairy roots, adventitious root culture, elicitation strategies, and endophytic fungi has been adopted for the production of CPT to meet the increasing demand without affecting the source plant's existence. Currently, another strategy to increase camptothecin yield by genetic manipulation is underway. The present review discusses the plants and endophytes that are employed for camptothecin production and throws light on the plant tissue culture techniques for the regeneration of plants, callus culture, and selection of cell lines for the highest camptothecin production. The review further explains the simple, accurate, and cost-effective extraction and quantification methods. There is enormous potential for the sustainable production of CPT which could be met by culturing of suitable endophytes or plant cell or organ culture in a bioreactor scale production. Also, different gene editing tools provide opportunities for engineering the biosynthetic pathway of CPT, and the overall CPT production can be improved . KEY POINTS: • Camptothecin is a naturally occurring alkaloid with potent anticancer properties, primarily known for its ability to inhibit DNA topoisomerase I. • Plants and endophytes offer a potential approach for camptothecin production. • Biotechnology approaches like plant tissue culture techniques enhanced camptothecin production.

Shinde AN, Malpathak N, Fulzele DP. Studied enhancement strategies for phytoestrogens production in shake flasks by suspension culture of Psoralea corylifolia. BIORESOURCE TECHNOLOGY 2009; 100:1833-9. [PMID: 19013062 DOI: 10.1016/j.biortech.2008.09.028] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/03/2008] [Revised: 09/12/2008] [Accepted: 09/17/2008] [Indexed: 05/07/2023]
Abstract
This study proposed secondary metabolites incremental yield due to manipulation of nutrient components into the culture medium. To validate this, the effects of nutrients such as carbon, phosphate and nitrogen on growth and production of phytoestrogens daidzein and genistein by suspension cultures of Psoralea corylifolia was investigated for the first time. The maximum production of daidzein and genistein was achieved when sucrose and maltose used as a sole source of carbon. Suspension cell cultures enriched with sucrose (3%) stimulated accumulation of isoflavones daidzein (1.76% dry wt) and genistein (0.25% dry wt) compared to glucose, fructose and maltose. Sucrose feeding strategy significantly stimulated biomass growth and isoflavones (2.79% dry wt of daidzein and 0.32% dry wt of genistein) production rate. Reduced concentrations of phosphate (0.625 mM) promoted daidzein (1.89% dry wt) and genistein (0.26% dry wt) production by suspension cell cultures, whereas high amount (5mM) in medium was inhibited isoflavones production. It was observed that medium fortified with NH(4)(+) and NO(3)(-) alone inhibited production of isoflavones. The maximum production obtained of daidzein (2.20% dry wt) and genistein (0.29% dry wt) when medium comprised with NH(4)(+)/NO(3)(-) at ratio 20:40 mM as a nitrogen source. Similar nutrient components ratio when altered NH(4)(+)/NO(3)(-); 40:20mM) resulted in approximately 3-fold decrease in production. HPLC analysis revealed that suspension cells cultures leached out trace amount of daidzein and genistein into the culture medium.
