The leaves of the Erythroxylum coca Lam., commonly referred to as the coca tree or coca plant, have a tea-like scent and contain between 0.25% and 1.3% of a stimulating substance known as cocaine. While the production of cocaine has evolved to become a means of pest control, the exhilarating effects of the substance caught the attention of ancient Andean dwellers. For thousands of years, indigenous people have chewed coca leaves or brewed them to help ward off fatigue, hunger, and particularly altitude sickness, known as "soroche." Planting coca in the mountainous regions of South America has become a lucrative profession, with as many as four harvests per year. In Peru or Bolivia, coca leaf extract is added to beverages, candies, cookies, and toothpaste. On the other hand, pure cocaine extracted from the leaves has potent medical uses.
The synthesis of cocaine is a highly complex process that scientists have been studying for decades. This knowledge is not only valuable to the pharmaceutical industry, which can create structurally similar compounds, but also to biologists interested in understanding the evolution of natural insecticides in the plant world.
Until now, scientists at the Kunming Institute of Botany in China have only recently managed to understand the final crucial stage of cocaine biosynthesis, even reconstructing this process in a modified plant - tobacco (which synthesizes nicotine and also has insecticidal properties).
According to experts, although the cultivation of this tobacco is not more profitable than ordinary coca, similar modifications can be made to yeast or bacteria for pharmaceutical purposes.
Cocaine belongs to a group of organic molecules known as tropane alkaloids. Other alkaloids in this group include atropine and hyoscyamine, which are produced by the plant Atropa belladonna and have long been used in medicine for dilating pupils, paralyzing salivary glands during surgery, and relieving irregular heart rhythms.
In chemistry, cocaine and methamphetamine share many similarities and have recently been found to originate from the same precursor molecule called 4-(1-methyl-2-pyrrolidinyl)-3-oxobutyric acid (MPOA).
The structure differences between two molecules are small but significant. It has long been a mystery how coca plants convert MPOA into cocaine. Now, a pair of enzymes called EnCYP81AN15 and EnMT4 have been identified. While the synthesis process is not yet fully understood, scientists say that the known enzymes are capable of synthesizing it.
Chinese scientists have demonstrated the ability of tobacco plants, specifically Nicotiana benthamiana, to produce cocaine by introducing six genes involved in the production of the drug. These hybrid plants were able to utilize their own enzymes to fill the gaps in the synthesis process, resulting in the production of cocaine within the modified tobacco plants.
According to the author of the study, gaining an understanding of the synthetic process can lead to the creation of novel biologically active compounds, potentially allowing scientists to improve formulations and discover more effective compounds.
