16*32 Many tumors of the breast are correlated with estrogen levels in the body. Drugs that interfere with estrogen binding have antitumor activity and may even help prevent tumor occurrence. A widely used antiestrogen drug is tamoxifen. kJ1 Name the functional groups in tamoxifen. Classify the amino group in tamoxifen as primary, secondary, or tertiary. How many stereoisomers are possible for tamoxifen? (d, Would you expect tamoxifen to be soluble or insoluble in water? In blood?
A chemically modified guanidino group is present in cimetidine (Tagamet), a widely prescribed drug for the control of gastric acidity and peptic ulcers. Cimetidine reduces gastric acid secretion by inhibiting the interaction of histamine with gastric H2 receptors. In the development of this drug, a cyano group was added to the substituted guanidino group to alter its basicity. Do you expect this modified guanidino group to be more basic or less basic than the guanidino group of arginine? Explain.

Here's what R, looks like: -CH- -- CH2 OH O yes Could R, form a hydrogen bond with R₂ at physiological pH, if R₂ were the right kind of residue? O no If you said R, could form a hydrogen bond with R2, what would R₂ have to be? If there's only one possibility, write its 3-letter code.
