Described are compounds for targeting proteases, e.g. serine proteases and their use in the diagnostic methods and methods for treatment of respiratory diseases such as cystic fibrosis. The compounds have the structure [H]-[B]-[A]; wherein [H] is a hydrophilic group, [B] is a subsite recognition group and [A] is a binding group; wherein A has the formula: -C(0)-CH2-NR1-COOR2 and wherein [B] has the structure :(i)-[CO-CH2- NR3]m-, or (ii)-[AA1-AA2]- or (iii) -(AA1-C0-CH2NR3)- or (iv) -(CO-CH2-NR3- AA1)- or (v) -(C0-CH2-NR4-AA1-AA3)-.
