While (S)-ibuprofen is the active ingredient, commercial ibuprofen is sold as a racemic drug because (R)-ibuprofen is non-toxic. Nonetheless research is ongoing to achieve enantiopurity as (S)-ibuprofen is 3 times as effective as the mixture and with less side-effects. Currently, a research lab published a method to produce (S)-ibuprofen that is 94% e.e. Which of the following statements is TRUE based on the information provided? The research lab's product contains 6% of (R)-ibuprofen. O Commercial ibuprofen has 50% enantiomeric excess. O The research lab's product sample will have a negative value for its observed rotation. O Commercial ibuprofen sample is optically inactive.

In early 1960s, the National Cancer Institute was able to isolate a complex organic compound from the bark of the Pacific Yew, Taxus brevifolia. The structure of the cancer-fighting component of yew bark was determined in 1962, and the compound was names paclitaxel (Taxol). Taxol is an anticancer agent active against ovarian, breast, and some lung tumors. Given the structure of Taxol, identify and place an asterisk at the stereogenic or chirality centers present within its complex structures. (Hint: There are only 11 chirality centers).

Paroxetine (Paxil) is an antidepressant that is a member of a family of drugs known as Selective Serotonin Reuptake Inhibitors (SSRIS). This family of drugs also includes fluoxetine (Prozac) and sertraline (Zoloft). SSRIS work by inhibiting the reuptake of the neurotransmitter serotonin in the synapses of the central nervous system follow- ing release of serotonin during excitation of individual nerve cells. Between firings, the serotonin is taken back up by a nerve cell in preparation for firing again. Inhibition of reuptake has the effect of increasing the time serotonin molecules remain in the syn- apses following excitation, leading to a therapeutic effect.
