Nature's Way To Make the Lantibiotics Heather A. Relyea and Wilfred A. van der Donk
This article focuses on one class of antimicrobial compounds, the lantibiotics, and discusses their biosynthetic pathways as well as their molecular mode of action. In the course of the review, the meaning of the terms regio-, chemo-, and stereoselectivity are discussed.

A Green Polymerization of Aspartic Acid for the Undergraduate Organic Laboratory George D. Bennett
Based on a technology that won a Presidential Green Chemistry Challenge Award, this experiment involves the thermal polymerization of aspartic acid and subsequent hydrolysis to give sodium poly(aspartate). The procedure is suitable for introducing students to the important topic of polymers and for illustrating several of the principles of green chemistry.

A Supramolecular Approach to Medicinal Chemistry: Medicine Beyond the Molecule David K. Smith
This article emphasizes a conceptual view of medicinal chemistry, which has important implications for the future, as the supramolecular approach to medicinal-chemistry products outlined here is rapidly allowing nanotechnology to converge with medicine. In particular, this article discusses recent developments including the rational design of drugs such as Relenza and Tamiflu, the mode of action of vancomycin, and the mechanism by which bacteria develop resistance, drug delivery using cyclodextrins, and the importance of supramolecular chemistry in understanding protein aggregation diseases such as Alzheimer's and CreutzfieldJacob.

Immunoassay, DNA Analysis, and Other Ligand Binding Assay Techniques: From Electropherograms to Multiplexed, Ultrasensitive Microarrays on a Chip Roger P. Ekins
"Ligand" or "binding" assays have made a major impact on biomedical research and clinical diagnosis since their development in the late 1950s. Immunoassay techniques (relying on specific antibodies to bind the target analyte) represent the best-known example, but analogous DNA and RNA analysis methods (using oligonucleotides to recognize defined polynucleotide sequences) are rapidly gaining in importance and are likely to exert profound effects on human society.
