2017 New Jersey Chemistry Olympics - Information Search: Home

This site provides a list of resources to help high school students participating in the Information Search

This Page is Only for the Information Search Competition

If you are looking for the web page for the entire 2017 New Jersey Chemistry Olympics please access http://njchemistryolympics.com/ .  May 18, 2017 is the date of the next event which is now in the planning stages.  More information will be posted later.  Please contact Natalie Macke at nmacke@pascack.k12.nj.us if you would like to participate in the 2017 event.

Molecular Modeling

In the first part of the event, you presented a representation of one of 4 analgesics.  In Part II you will be asked to find information about those drug substances that you will find by searching the internet using the list of databases below or by searching Google.  The substances are:

  • Ciramadol (RN=63269-31-8)
  • Ibuprofen (RN=15687-27-1)
  • Naproxol (RN=26159-36-4)
  • Lefetamine    (RN=7262-75-1) 

You must answer all the questions, not just the one that includes the molecule you presented in part I.

Suggested Databases for the Information Search

You may use the databases listed below or the ones offered by NJIT at http://library.njit.edu/databases/databases-alpha.php

Behavioral and brain temperature responses to salient environmental stimuli and intravenous cocaine in rats: Effects of diazepam

(2008) Psychopharmacology, 196 (3), pp. 343-356. Cited 5 times.

ABSTRACT: Rationale: While diazepam is an effective anxiolytic and somnolent drug in humans, its physiological and behavioral effects in animals are often variable. Differences in basal activity state (basal arousal) may be important in determining both this response variability and the pattern of drug influence on behavioral and physiological responses to natural arousing stimuli and other drugs. Objectives: To evaluate the changes in brain, muscle, and skin temperatures, and in locomotion induced in rats by several arousing stimuli and intravenous (i.v.) cocaine; and to assess how these responses are modulated by diazepam at a relatively low dose (1 mg/kg, i.p.). Materials and methods: Male rats were implanted with thermal probes in the nucleus accumbens (NAcc), temporal muscle, and subcutaneously, and equipped with a chronic i.v. catheter. They were exposed to 1-min tail-pinch, 1-min social interaction with another male and cocaine (1 mg/kg, i.v.) after administration of diazepam or saline. Results: While the injection of either diazepam or saline resulted in similar locomotor activation and temperature responses, diazepam decreased basal brain and muscle temperatures for about 3 h; the temperature-decreasing effect of diazepam was oppositely related to basal brain temperature (r=-0.51). After diazepam, rats also showed weaker temperature and locomotor responses to both arousing stimuli; the effect was stronger for tail-pinch and for absolute temperature increases than relative changes. Although diazepam significantly decreased cocaine-induced locomotor activation, it had virtually no effects on cocaine-induced temperature responses in all locations. Conclusions: In accordance with the "law of initial values", the temperature- increasing effects of all tested arousing stimuli and temperature-decreasing effect of diazepam depend upon basal brain temperature. The greatest temperature effects are seen with arousing stimuli at low basal arousal (increases) and with diazepam at high basal arousal (decreases). This is a likely explanation for the variability seen with the physiological and behavioral effects of diazepam in animals
