- Label the two stereogenic centers in each compound and draw all possible stereoisomers.arrow_forwardCitalopram is an antidepressant pharmaceutical that is sold as a racemic mixture. However, it is known that the (S) enantiomer is 30x more biologically active than the (R) enantiomer. Draw the (S) configuration.arrow_forwardWhich compounds (B–F) are identical to A? (b) Which compounds (B–F) represent an isomer of A?arrow_forward
- Part B. Mark each chirality center in each molecule with an asterisk (*). Illustrate onto the image Cannot be hand-drawnarrow_forwardPart B. Mark each chirality center in each molecule with an asterisk (*).arrow_forwardDraw both enantiomers of clopidogrel (trade name Plavix), a drug given to prevent the formation of blood clots in persons who have a history of stroke or coronary artery disease. Plavix is sold as a single enantiomer with the S conguration. Which enantiomer is Plavix?arrow_forward
- Saquinavir (trade name Invirase) is a protease inhibitor, used to treat HIV (human immunodeficiency virus). a.Locate all stereogenic centers in saquinavir, and label each stereogenic center as R or S. b.Draw the enantiomer of saquinavir. c.Draw a diastereomer of saquinavir. d.Draw a constitutional isomer that contains at least one different functional group.arrow_forwardPlease circle and assign absolute configuration of the chirality centers. Then draw the enantiomer compound. Thank you so much!arrow_forwardLabel compounds B–D as stereoisomers, conformations, or constitutional isomers of Aarrow_forward
- For the following molecules: a. How many stereogenic centers are present? b. How many stereoisomers are possible for these molecules?arrow_forwardAssign R and S, is this an enantiomer, diastereomer, constitutional isomer, or identical?arrow_forwardDraw both enantiomers of clopidogrel (trade name Plavix), a drug given to prevent the formation of blood clots in persons who have a history of stroke or coronary artery disease. Plavix is sold as a single enantiomer with the S configuration. Which enantiomer is Plavix?arrow_forward
