Synthesis of Albendazole Metabolite: Characterization and HPLC Determination Graciela Mahler, Danilo Davyt, Sandra Gordon, Marcelo Incerti, Ivana Núñez, Horacio Pezaroglo, Laura Scarone, Gloria Serra, Mauricio Silvera, and Eduardo Manta
In this laboratory activity, students are introduced to the synthesis of an albendazole metabolite obtained by a sulfide oxidation reaction. Albendazole as well as its metabolite, albendazole sulfoxide, are used as anthelmintic drugs. The oxidation reagent is H2O2 in acetic acid. The reaction is environmental friendly, fast, and proceeds with high yield. The crude reaction is analyzed by HPLC chromatography to determine purity. The simplicity of the experiment allows students to study chiral concepts, physicochemical and spectroscopic properties of the compounds, and HPLC determinations.

From the Research Bench to the Teaching Laboratory: Gold Nanoparticle Layering Maria Oliver-Hoyo and Ralph W. Gerber
The procedures presented here involve the synthesis of gold colloidal suspensions, attachment of a functional group to glass with subsequent creation of self-assembled monolayers through deposition of gold nanoparticles, and measurements of wavelengths, absorbance, and conductivity.

The Discovery and Development of Cisplatin Rebecca A. Alderden, Matthew D. Hall, and Trevor W. Hambley
Cisplatin is currently one of the most widely used anticancer drugs in the world. The unlikely events surrounding the discovery of its anticancer activity, subsequent introduction into the clinic, and the continuing research into platinum compounds is the subject of this review.

Volatile Organic Sulfur Compounds of Environmental Interest: Dimethyl Sulfide and Methanethiol. An Introductory Overview Thomas G. Chasteen and Ronald Bentley
Volatile organic sulfur compounds and their degradation products play important environmental roles in global warming, acid precipitation, and cloud formation. Two important members of this group, dimethyl sulfide, DMS, and methanethiol, MT, are formed by living organisms as well as by abiotic processes. The chemical reactions responsible for the biosynthesis of DMS and MT are emphasized here, as well as means for their degradation. Since sulfur compounds are often ignored in normal course work, this article provides a basic foundation for an understanding of these interesting and environmentally significant compounds.

Kinetics of Papain: An Introductory Biochemistry Laboratory Experiment Kathleen Cornely, Eric Crespo, Michael Earley, Rachel Kloter, Aime Levesque, and Mary Pickering
In this experiment, we investigate the kinetics of the thiol protease papain. A specific substrate, Na-benzoyl-arginine-p-nitroanilide (BAPNA), is used, which takes advantage of the fact that papain interacts with a phenylalanine residue two amino acids away from the peptide bond cleaved. Upon hydrolysis by papain, a bright yellow product is released, p-nitroaniline. This allows the reaction to be monitored spectrophotometrically by measuring the rate of formation of the p-nitroaniline product as a function of the increase in absorbance of the solution at the lmax of p-nitroaniline (400 nm) over time at various substrate concentrations. These data are used to plot a Lineweaver-Burk plot from which the vmax and KM are obtained.
