A recent study conducted by chemists from the University of New Brunswick has the potential to transform the production process of certain drugs. Collaborating with researchers from Zhejiang and Westlake universities in China, the UNB team has uncovered the mechanism by which certain plants synthesize cancer-fighting drugs.
The lead researcher, Yang Qu, an associate professor of chemistry at UNB, stated that understanding the natural production process of these drugs could facilitate their laboratory synthesis at a significantly accelerated rate. Qu highlighted that their findings have resulted in a remarkable increase in production efficiency, with the ability to generate the drug nearly 1,000 times more effectively than previous methods.
Published in the academic journal Science, the study delves into the challenges associated with manufacturing vinblastine, a crucial drug utilized in treating various types of cancer such as bladder, brain, and testicular cancer. Vinblastine is exclusively sourced from the Madagascar periwinkle plant, which, despite its medicinal properties, yields the drug in minimal quantities.
Qu emphasized the inefficiency of the plant, noting that it requires 100 kilograms of dried plant material to produce just one gram of vinblastine, making the process economically and logistically burdensome. The complexity of vinblastine further complicates its chemical synthesis, contributing to its costly production.
Through their research, the team uncovered that the Madagascar periwinkle employs a unique approach to drug synthesis by utilizing scaffold proteins. These proteins serve as organizers, enhancing the assembly of drug components in a manner akin to scaffolds on a construction site, optimizing efficiency and speed of production.
By introducing the scaffold protein into the plant’s microbial system, researchers anticipate a significant enhancement in the drug production process. While the medical breakthrough has not yet translated into immediate commercial benefits, Qu expressed optimism about the potential impact on industrial production, bringing the realization of widespread drug availability closer to fruition. He anticipates tangible applications emerging from this research in the foreseeable future.
