Stereochemistry Considerations What would you think if I gave you a drug and said this is going to help you but I want you to know ahead of time that 50% of the dose is not affected, in fact the drug is 50% not pure. The idea of that would make you feel you want another drug. The reality of that is that a large # of drugs we give are 50% impure and the reason is b/c …showed first 75 words of 4591 total…

…showed last 75 words of 4591 total…the RR, SS, RS, SR isomers. What you will notice is that if you look at the alpha 1 activity the SR isomer is the most potent. If you look at the beta 1 activity you can see that the RR isomer is the most potent and if we look at beta 2 activity the RR isomer is also the most potent there. So here we have multiple activities of the drug with different potencies with different isomers.
