First Assignment
My Expectations of YouIntroduction to Chemistry 32B - Spring 2009
1. Read the chapter before lecture
2. DO ALL THE ASSIGNED HOMEWORK PROBLEMS - Understand
3. Do not wait until last minute to Study(Unlike BIO, O-Chem cannot be crammed the night before)
4. Plan to set aside, min 3-4 hrs/ day reading the chapter, answering Homework Qs
5. O-Chem not terribly difficult . . .really . . . It just takes a lot of time to master, unlike most science classes
6. GET SERIOUS, Just study (3-4hrs/day) and you should be fine
Most test Qs -- from H-work directly or very similar and Lecture Problems

Pharmakokinetic Analysis of Fijianolide B
Pharmacokinetic analysis of 2 in HCT-116 tumor-bearing SCID mice. The observed concentration of 2 in the plasma (●) and HCT-116 tumor (■) over a 24h period (1440 minutes). At 24h concentration of 2: plasma = 0.2 ug/mL, tumor = 2.8 ug/mg.

In vivo Evaluation of Fijianolide B
In vivo assessment of 2 using HCT-116 tumor-bearing SCID mice. The average tumor weight measured per day after daily inoculation of 2 for 5 days: 25 mg/kg/day (■), 12.5 mg/kg/day (▲), and control (♦).
