Medicinal chemistry and chemical biology are stimulating fields that connect many scientific disciplines and allow for collaboration with other scientists in a wide variety of opportunities. The objective is to contribute to the understanding of the relationships between molecular structure and biological activity, embracing the interfaces between chemistry and biology. Some specifics areas include: design, synthesis, and biological evaluation of novel compounds; structural investigation of small-molecule ligands and biological targets; development of structure-activity relationships (SAR); new methodologies and applications in chemical informatics, molecular modeling, chemical databases and computer-aided drug design; the understanding and manipulation of biological systems with molecular precision; in vitro and in vivo investigations, cell biological methods, and organismic studies; mechanistic studies on proteins, nucleic acids, sugars and lipids; studies of cellular function from both chemical and biological perspectives; and others. The MD symposia aim to cover all the latest outstanding developments in medicinal chemistry and chemical biology, presenting original research opportunities and discoveries in these fields. This will be an important international forum to facilitate the communication that blend chemistry, biology and allied disciplines in new ways.
