Biological Activity

DAPTA (D-ala-peptide T-amide, Adaptavir) is an HIV gp120-derived CCR5 entry inhibitor, inhibits CCR5-mediated monocyte migration and attenuates neuroinflammation, shows potent anti-HIV activities.
DAPTA potently inhibits specific CD4-dependent binding of gp120 Bal (IC50 = 0.06 nM) and CM235 (IC50 = 0.32 nM) to CCR5.
DAPTA (1 nM) blocks formation of the gp120/sCD4 complex with CCR5. DAPTA inhibits the binding of gp120BaL/sCD4 to CCR5 (Cf2Th/synR5) cells with IC50 of 55 pM.
DAPTA administration significantly decreased marble burying and repetitive behavior in BTBR mice.
DAPTA treatment inhibited CCR5+, CD4+CCR5+, CCR5+IL-6+, CCR5+IL-9+, CCR5+IL-17A+, CCR5+RORγT+, and upregulated CCR5+IL-10+, and CCR5+Foxp3+ production.
DAPTA downregulated IL-6, IL-9, IL-17A, and RORγT, and increased IL-10 and Foxp3 protein and mRNA expression.
