Tyr-α-CGRP (human) Usage And Synthesis

Description

Tyr-α-CGRP is an N-terminal extended tyrosinated analogue of α-calcitonin gene-related peptide (α-CGRP; ).¹ It binds to amylin receptors AMY₁ and AMY₃ in COS-7 cells expressing the human receptors (IC₅₀s = 141 and 1.86 nM, respectively).² Tyr-α-CGRP also binds to and stimulates cAMP accumulation in rat L6 myocytes (IC₅₀ = 4 nM; EC₅₀ = 12 nM).¹ It also binds to rat brain and spleen membrane preparations (IC₅₀s = 0.2 and 0.5 nM, respectively), induces positive chronotropic and inotropic effects in isolated right and left guinea pig atria (EC₅₀s = 282 and 74 nM, respectively), and inhibits the twitch response in rat vas deferens (EC₅₀ = 1.9 nM).³
