DAPTA trifluoroacetate，1MG，SML3265-1MG，Sigma

Biochem/physiol Actions

DAPTA is a potent CCR5 antagonist, an amidated octapeptide corresponding to an HIV envelope glycoprotein gp120 (gp160)-derived sequence (aa 185-192; the SF-2 isolate) that competes against gp120-CD4 complex for interaction with CCR5 (IC50 = 0.42 nM against gp120CM235 binding to CCR5/CD4 cells, IC50 = 1.5/1.8 nM against gp120BaL/sCD4 or gp120CM235/sCD4 binding to CCR5+/CD4- cells). DAPTA blocks CCR5-dependent HIV host cell entry in cultures and in vivo.
