Dnp-P-Cha-G-Cys(Me)-HA-K(Nma)-NH2 is a fluorogenic substrate for matrix metalloproteinase-1 (MMP-1) and MMP-9. Upon cleavage by MMP-1 or MMP-9, N-methylanthranilic acid (Nma) is unquenched and its fluorescence can be used to quantify MMP activity. Nma displays excitation emission spectra of 340 440 nm, respectively.
N3-D-Orn(Boc)-OH (CHA) is a Boc-protected derivative of the pentanoic amino acid used in click chemistry and the synthesis of antibody-drug conjugates (ADC) [1].
Potent and selective human vasopressin V1B receptor agonist (Ki values are 1.2, 151, 240 and 750 nM for V1B, V1A, Oxytocin and V2 receptors respectively). Stimulates ACTH and corticosterone secretion and exhibits negligible vasopressor activity in vivo.
