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.
