Identification, characterization, and structure activity relationship of the ASIC3 selective peptide WRPRFa Communications Chemistry Not too big. Not too small. Because of their intermediate size, macrocyclic peptides combine the potency and precise targeting of an antibody or biologic therapy with the stability and ease of administration of a Identification, characterization, and structure activity relationship of the ASIC3 selective peptide WRPRFa Communications Chemistry Organic Nitrate Therapy, Nitrate Tolerance, and Nitrate Induced Endothelial Dysfunction: Emphasis on Redox Biology and Oxidative Stress Andreas Daiber, Thomas Mnzel, 2015
