Molecular Models of Real and Mock Illicit Drugs from a Forensic Chemistry Activity  William F. Coleman
The Featured Molecules for this month have been drawn from a forensic chemistry exercise in which model compounds are used to simulate the behavior of various drugs in a series of chemical tests. The compounds considered include chlorpromazine (Thorazine) and phenothiazine, both involved in the manufacture of antipsychotic drugs.

Using Laboratory Chemicals To Imitate Illicit Drugs in a Forensic Chemistry Activity  Shawn Hasan, Deborah Bromfield-Lee, Maria T. Oliver-Hoyo, and Jose A. Cintron-Maldonado
This forensic chemistry activity utilizes forensic procedures (chemical spot tests and thin-layer chromatography) on laboratory chemicals that mimic actual street drugs to produce screening results similar to those for controlled substances.

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 CreutzfieldJacob.

Molecular Models of Real and Mock Illicit Drugs from a Forensic Chemistry Activity  William F. Coleman
The Featured Molecules for this month come from the paper by Shawn Hasan, Deborah Bromfield-Lee, Maria T. Oliver-Hoyo, and Jose A. Cintron-Maldonado (1). The authors describe a forensic chemistry exercise in which model compounds are used to simulate the behavior of various drugs in a series of chemical tests. Structures of a number of the chemicals used in the experiment, and several of the drugs they are serving as proxy for, have been added to the molecule collection. Other substances used in the experiment are already part of the collection, including caffeine and aspirin. One structure that may be both intriguing and confusing to students is that of chlorpromazine (Thorazine, Figure 1). A majority of students might well expect the ring portion of the molecule to show a planar structure. This is not what is found from calculations at the HF/6311++G(d,p) level in both the gas phase and in water. Instead, the three rings are in a V-like formation with a deformation of approximately 50 degrees from planarity. Tracking down the source of this non-planarity would be a useful computational exercise. Does it arise from the presence of the alkyl chain (steric effect), from the chloro group (electronic effect), or from electronic effects involving the elements of the heterocyclic ring? As a starting point to addressing these questions, students could be introduced to the use of model compounds in computation. One such compound would be the parent ring system phenothiazine (Figure 2). That molecule contains neither a chloro substituent nor an extended alkyl group. Is it also found to be non-planar? Is the deformation angle the same, larger, or smaller than in chlorpromazine? Does the addition of chloro group to phenothiazene change the angle significantly? What about the addition of an alkyl group? If the model compound is forced to be planar are all of the vibrational frequencies real (positive)? If not, what type of deformation is suggested by the imaginary (negative) vibration?
