Novel method enables quick identification of small active substance molecules

Secondary natural substances that occur in numerous plants, bacteria and fungi can be anti-inflammatory, can ward off pathogens or even prevent the growth of cancer cells. However, making use of the riches provided by nature's medicine cabinet and identifying new natural substances is time-consuming, costly and labour-intensive. A team of bioinformaticians at Friedrich Schiller University Jena has now developed a method that enables much faster and easier identification of small active substance molecules.
