A range of substituted biphenyls have been evaluated as antagonists of the GPCR neurokinin-1 (NK1) , a target for the treatment of cancer chemotherapy endured nausea and vomiting. With reference to table 1, discuss the structure activity relationships related to the nature of the substituent R1 and linker group L. In your answer, aim not just to identify trends, but to give possible explanations to them. Include as much detail as possible.

Polylysine adopts a random structure in solution at physiological pH (i.e. 7.4). Given that the e-amino group of lysine has a pKa of 10.5, under what circumstances do you think polylysine will form an a-helix? Give an explanation for your decision.   Given the pKa of the side-chain COOH group, under what circumstances would you anticipate polyglutamate to form an a-helix?
