• EXPOSITION •

Admission to the exposition is complimentary for all na­tional meeting registrants. While planning your sched­ule in Denver, reserve some time to visit the ACS National Exposition. In addition to functioning as a showcase for the most up-to-date scientific products and services, the ex­position also serves as a valu­able source of continuing ed­ucation for national meeting attendees.

Located in the Colorado Convention Center (Halls A & B), the exposition will be open Monday and Tuesday, March 29 and 30, from 9 AM to 5 PM, and Wednesday, March 31, from 9 AM to 4 PM. The exposition will con­sist of about 350 booths, rep­resenting almost 210 compa­nies and organizations dis­p lay ing eve ry th ing from instruments and books to computer hard­ware and software. Also displayed will be chromatographic and lab equipment, fur­niture, and safety equipment.

Each exhibiting organization will have expert personnel on hand to give dem­onstrations, answer questions, and dis­cuss your needs and interests. In addi­tion to the comprehensive display of products and services of interest to the scientific community, there will be give­aways, several drawings for prizes, and a free ACS souvenir for all visitors to the exposition.

Science on Wheels Display. When you visit the exposition, stop by the scientif­ic van display located in the back of the hall by the restaurant. Four vans, which serve as mobile educational labs, will be available for inspection. The vans func­tion as traveling outreach programs, taking chemistry to the public, particu­larly students.

Admission Requirements. Although admission to the exposition is compli­mentary for all national meeting regis­trants, a badge is required to enter the exhibit hall. Badges will be mailed to all preregistrants; on-site national meeting registrants may obtain a badge at the main registration area in the Colorado Convention Center.

Those not registering for the meeting, but interested in visiting the exhibits, can obtain an exhibits-only badge for $20. Students with school identification will be charged $5.00. There will be no

preregistration for exhibits-only attend­ees; exhibits-only badges can be pur­chased at the main registration area in the Colorado Convention Center.

Exposition Workshops. A series of expo­sition workshops will be conducted in Denver and will cover a variety of topics. Attendance will be limited and restricted to workshop registrants (see preregistra­tion form on page 111).

4. Structural Access to Metabolic Trans­formations.

Sponsor: Molecular Design Ltd. Instructor: Louise Henriksen. Noon to 1 PM. Room 212.

Information on metabolic transformations of chemicals is dispersed in the literature and in

secondary sources, and structural access is very difficult. This workshop presents a new structure-based database of metabolic trans­formation of drugs and illustrates use of the database in drug design and metabolism studies.

5. Prediction & Visualization of Molecular Properties & Reactivity.

Sponsor: CAChe Scientific. Instructor: David Gallagher. 1 to 3 PM. Room 208.

The prediction of properties such as UV-Vis spectra (color), IR spectra, solubility, stability, acidity, and nucleophilicity are often important in the design of a wide variety of chemicals, including photographic dyes, polymers, in­secticides, drugs, herbicides, pharmaceuti­cals, and catalysts. New generation of tools for the experimental chemist will be de­scribed. The tools not only predict many properties, but also correlate them directly to the molecular structure, providing insight that is not available by other experimental tech­niques.

6. New Advances in the Estimation of LogP and Solvation-Free Energies.

Sponsor: Molecular Simulations. Instruc­tor: Mario Blanco. 1 to 3 PM. Room 210.

A quantitative understanding of molecular so­lution properties is critically important to bio­chemistry, medicine, materials, the environ­mental sciences, and drug design. In the past, predictive models have been either too expensive to be of practical use or not accu­rate enough. POLARIS, a new method that includes all key energetic contributions of molecules in solution, will be presented.

It will also explore what further progress can be expected in the future.

Part A

Chemical Property Estimation for Risk Assessment Zoltan Bencz, Ph.D. Certain physico-chemical properties are quantitatively related to both chemical substructure and to factors of importance in the risk assessment process. Examples of such QSAR are logP, a measure of lipophilicity which is a determinant of bioaccummulation and Pka, a dissociation constant which is intimately related to uptake, distribu­tion, and excretion of chemicals. In the many instances which it is not practical or possible to measure the values, the artificial intelligence-based programs such as PROLOGP and pKalc can fill the gap. The theoretical basis of these programs and their use and integration with other programs will be discussed in this session.

+ 9:00 - 9:45 and 1:00 - 1:45

Predictive Toxicity for Risk Assessment Harold H. Borgstedt, M.D. Risk assessment often has to be achieved based on few, if any, biological test data on toxicity to mammals, birds, fish, or environmental organisms. Toxicity modeling attempts to fill this gap by supplying credible estimates of toxicity using computer-based calculations. The major models available for producing toxicity estimates will be reviewed. The HazardExpert program, which utilizes modern artificial intelligence techniques, will be dis­cussed in detail. • 9:45 -10:30 and 1:45 - 2:30

9:00 AM and 1:00 PM

PartB

Assessing Biotransformation and Degradation D. Ferenc Darvas, Ph.D. The overall toxicity of organic chemicals is determined in large measure by the toxicity of their metabolites. Because of the great time and monetary requirements of experimental metabolic studies, computer-based predic­tive metabolism programs (CAMP) have been developed to provide semiquantitative predictions of putative metabolites rapidly and inexpensively. The MetabolExpert program utilizes modern artificial intelli­gence techniques to provide such predictions in an efficient, user-friendly environment. Its theoretical basis and general functionality will be discussed, as well as its integration with other programs.

• 11:00 -11:45 and 3:00 - 3:45

Tools for Chemical Fate and Transport Modeling James O. Pilotte, M.A., M.S. This presentation will provide an introduction to fate and transport modeling of organic chemicals in surface water, soil, and groundwater media. The discussion will consider data requirements, modeling approaches, and applications of modeling results to risk assessment. Models covered include EXAMS-II, SESOIL, AT124D, and the RISKPRO exposure assessment package. • 11:45 -12:30 and 3:45 - 4:30
