New findings from chemists at the University of New Brunswick may bring about a significant transformation in drug manufacturing processes. Collaborating with researchers from Zhejiang and Westlake universities in China, the UNB team has unraveled the mechanism by which certain plants produce cancer-fighting drugs.
According to Yang Qu, an associate professor of chemistry at UNB who spearheaded the research, understanding how plants synthesize these drugs could pave the way for accelerated lab production. The team’s breakthrough has demonstrated a remarkable increase in efficiency, with the potential to achieve drug production levels nearly 1,000 times higher than previously recorded values.
The study, featured in the latest issue of the academic journal Science, delves into the challenges associated with manufacturing vinblastine, a vital drug used in treating various cancers such as bladder, brain, and testicular cancer. Despite its efficacy, vinblastine’s production is hindered by its exclusive sourcing from the Madagascar periwinkle plant, resulting in limited output.
Qu highlighted the plant’s inefficiency in drug production, revealing that a substantial amount of plant material is required to yield a minute quantity of vinblastine. The complexity of the drug further complicates its chemical synthesis, rendering the process both arduous and costly.
The researchers shed light on the Madagascar periwinkle’s unique approach to drug synthesis. Unlike typical plant enzymes that catalyze reactions, this plant employs a specialized “scaffold protein” to facilitate the drug’s assembly. Qu likened the scaffold protein to a construction site scaffold, optimizing the arrangement of components and expediting the synthesis process significantly.
By integrating this scaffold protein into the plant’s microbial system, researchers anticipate a boost in production efficiency, although tangible outcomes in drug manufacturing are yet to materialize. Nevertheless, Qu expressed optimism regarding the industrial viability of the research, bringing the prospect of enhanced drug production closer to realization.
The potential implications of this medical advancement are substantial, with Qu foreseeing practical applications emerging in the foreseeable future.
