Investigation of the (A) role of the proline ring and the (B) substituent attached to the amino group of proline in 1 for the inhibition of the Keap1–Nrf2 PPI. Dissociation constants were obtained by SPR using an ISA for 1 and 23–37 and also by ITC for compound 1. Mean values ± standard deviation derived from a minimum of three experiments are reported.
