Nearly two centuries after scientists first isolated one of the most chemically complicated substances produced by plants, researchers are uncovering a new way to explore the medicinal possibilities hidden inside two famously poisonous flowers. Wolfsbane and larkspur may be capable of causing severe nerve damage and paralysis in extremely small doses, yet the same plants produce extraordinary molecules that could eventually inspire treatments for pain, malaria, cancer and other applications. A new study from scientists at Michigan State University and the Czech Academy of Sciences has identified six enzymes involved in producing a complex compound called atisinium, offering researchers a potential biological route for studying rare plant chemicals on a larger scale.
The discovery highlights a remarkable paradox in natural medicine: substances capable of harming the human body can also provide clues for developing useful therapies. Plants have spent millions of years evolving sophisticated chemical defenses against predators, disease and environmental threats. Humans have repeatedly learned how to study those molecules and, in some cases, turn their unusual biological properties into medicines or other valuable products. Caffeine, menthol, capsaicin and vanillin are familiar examples of plant-derived or plant-inspired chemistry, while numerous modern medicines have roots in compounds first discovered in nature, according to Science Daily.
