Toronto Toronto Travel Information

Local Arrangements

Arrangements have been made with Air Canada, Canadian Airlines International, United Airlines, and U.S. Air for attendees to obtain discounted air fares to and from Toronto. These discounts are particularly advantageous for those not planning to be in Toronto over a Saturday night and who therefore do not qualify for published discounted fares. Because the number of seats available on any given flights is limited, it is very important that reservations be made as early as possible.

Congress Hospitality Centre. The Toronto Section, Chemical Institute of Canada (CIC), extends a cordial welcome to all members and guests attending the meeting. A Hospitality Centre will be operated in the Royal York, Confederation 4 Room, hosted by section members. Tickets for tours will be sold only in the Hospitality Centre. Information on other sightseeing opportunities in the area will be available as well. The hours of operation will be Sunday, noon to 7 PM; and Monday through Thursday, 8:30 AM to 5 PM. During the congress, tickets for tours will be sold only in the Hospitality Centre and only in Canadian dollars.

Air Canada: a 20% savings off the regular economy fare for delegates traveling within Canada (restrictions: maximum stay 15 days); 25 to 35% savings off the regular economy fare for delegates traveling from the U.S. (restrictions: minimum stay two nights; maximum stay 15 days; seven-day advance booking). Should delegates qualify for lower fares, their reservations will be confirmed at the lowest fare available. All reservations must be made through Air Canada's toll-free number 1-800-361-7585. Canadian Airlines International: includes Nordair Metro, Quebecair, Air Atlantic, Time Air, and Calm Air; a savings of 20% off the regular economy fare for travel within Canada. All reservations must be made through Canadian's toll-free number 1-800-268-4704.

All reservations must be made through United's toll-free number 800-521-4041 from continental U.S. and Canada (from Hawaii and Alaska, call 800-722-5243) and mention ACS account No. 8150D. These numbers are available seven days a week, from 8 AM to 11 PM Eastern time. Tickets may be purchased from United with credit cards or through your local travel agent, but to obtain the discount, reservations must be made through the 800 number. Because of government restrictions, no discounts are permitted from Mexico, the Bahamas, or the Orient. U.S. Air: a 30% savings off regular economy fare for round-trip travel, subject to "B" class availability; from June 1 through June 15. All reservations must be made through the toll-free number 1800-553-5653 [in District of Columbia, 861-7700] and mention Code No. BGSE28F.

Be sure to build some time into your schedule to attend the congress exposi­ tion at least once or twice during your stay in Toronto. There is no easier or more interesting way to keep abreast of the latest technology. See first-hand practical applications of the research you hear about in the symposia. Be sure to come by the Metro Toronto Conven­ tion Centre (Halls A & B) and take a look

at the largest spring exposition in ACS/ CIC history—about 400 booth spaces, occupied by more than 275 companies and organizations, will display every­ thing from instruments and books to computers (software and hardware) and laboratory furniture and safety equip­ ment, as well as the latest in chromato­ graphic and lab equipment. Each exhib­ iting organization will have expert per­ sonnel on hand to give demonstrations and/or discuss your needs and interests. Admission to the exposition is compli­ mentary. In addition to the comprehen­ sive display of products and services of interest to the scientific community, there will be free refreshments, give­ aways, and several drawings for prizes. All attendees also will receive a free congress souvenir. The exposition will be open Sunday, June 5, from 3 to 7 PM, and Monday, Tuesday, and Wednesday, June 6, 7, 8, from 9 AM to 5 PM. A full restaurant and lounge will be available on the ex­ hibit floor. Exposition Inquiry Card.

Chemical applications, from analytical to synthetic chemistry, that lend themselves to ChemBase databases will be discussed. Workshop shows how day-to-day project information can be better organized. ChemText, the chemical word processor, merges graphics and text to create reports, theses, specification sheets, slides/overheads, and anything else that requires printing images with text. Participants will learn how to do their own graphic design work, avoiding costly and time-consuming rework. As both of these programs are part of the Chemist's Personal Software Series, information can be shared between them. Transfer of ChemBase structures and tables into a ChemText report will be illustrated. No computer experience necessary.

14. Rapid, Molecular Screening of Chemicals for Drug Discovery Sponsor: Nova Pharmaceutical Corp. Instructors: Philip J. Monroe, Christopher H. Price 10 AM to noon Wellington Room Receptor/ligand and enzyme/substrate interactions are relevant targets for drugs that

block (antagonize) or stimulate (agonize) natural biochemical processes. The process of identifying molecules with drug potential has been revolutionized by receptor binding technology. Using this technology, rapid and lowcost screening of chemical libraries can be performed in vitro, quickly identifying compounds that have biological activity at specific receptors. Subsequently, these compounds can be examined for specific pharmacological activity in more advanced receptor binding assays, and data on structure-activity relationships can direct the synthesis of analogs in drug design programs. Thus, a screening program that involves multiple receptor binding assays can accelerate the discovery of lead compounds and shorten the time for their development as drugs. In addition, potential side-effects of promising compounds can be detected.

15. 3-D Graphics Issues for Molecular Modeling—Color Hardcopy Solutions Sponsor: Tektronix Inc. Instructor: To be announced 10 AM to noon; repeated at 2 to 4 PM Grenadier Room Developments and research in color hardcopy solutions and how they relate to molecular modeling applications will be presented in the morning session.
