The section on Development and Modification of Bioactivity is primarily focused on the supply of natural products, their use as lead sources for drug development, and their modification by biological means in the pursuit of improved activity.
The Chemical Ecology section contains articles covering all aspects of semiochemicals, be they pheromones or allelochemicals.
The section entitled Amino Acids and Their Derivatives, Peptides and Proteins covers a wide variety of subjects centered on the structural variety of amino acid and peptide-based natural products, on the their biosynthesis, and on their posttranslational modifications.
The nucleic acids section surveys ribo and 2-deoxyribonucleosides and nucleotides, including structure, modification, association with natural products, and function. The section also surveys the chemical synthesis of oligonucleotides.
