Selection, natural product drug development

The development of novel materials and the search for new bioactive compounds, such as natural products and analogues, drugs, diagnostics and agrochemicals, in academic and industrial chemistry is closely connected to the efficient preparation of such compounds. Thus, the view of synthesis has altered in recent years the development of new, highly selective methods will still be an important task, but the main focus of today s chemists is on efficiency [1], Multi-step syntheses with more than 20 steps have to be avoided since they are neither economically nor ecologically justifiable. Thus, modern syntheses must deal carefully with our resources and our time, must reduce the amount of waste formed, should use catalytic transformations and finally must avoid all toxic reagents and solvents. 

The selection and quality of a screening library with drug-like and lead-like structures is a critical endeavour. The features of drug-like and lead-like structures continue to be better defined, at the same time as the diversity of drug-like and lead-like molecular space continues to be explored and categorised. Other areas of development focus on the discovery of small molecules suitable for modulating protein-protein interactions, with a greater focus on natural product-like compounds.
