AH-D peptide
Based on 1 Customer Validation
AH-D peptide is a brain-penetrant antiviral agent disrupting highly curved lipid membranes. AH-D peptide exhibits broad-spectrum antiviral activity against ZIKV, Dengue virus, Chikungunya virus, yellow fever virus and Japanese encephalitis virus, with
IC50 values of 11.9, 12.5, 35.7, 206 and 136 nM, respectively. AH-D peptide reduces the viral load in the brain, suppresses inflammation, protects neurons, and does not damage the blood brain barrier. AH-D peptide restores antitumor immunity by decreasing circulating PD-L1+ exosomes, reducing intratumoral immunosuppressive cells (regulatory T cells, myeloid-derived suppressor cells), and enhancing T cell function. AH-D peptide inhibits membrane-enveloped viruses and cancer cell metastasis in vivo. AH-D peptide exhibits no immunogenicity and has negligible effects on normal tissues. AH-D peptide can be used for research in Zika virus and other mosquito-borne viruses, cancer immunotherapy and metastasis.

AH-D peptide restores antitumor immunity by decreasing circulating PD-L1+ exosomes, reducing intratumoral immunosuppressive cells (regulatory T cells, myeloid-derived suppressor cells), and enhancing T cell function. AH-D peptide inhibits membrane-enveloped viruses and cancer cell metastasis in vivo. AH-D peptide exhibits no immunogenicity and has negligible effects on normal tissues. AH-D peptide can be used for research in Zika virus and other mosquito-borne viruses, cancer immunotherapy and metastasis[1][2].
AH-D peptide (50-1000 nM) induces liposome rupture at 50 nM, with the rupture time shortening as the concentration increases (50-1000 nM)[1].
AH-D peptide (100 nM) preferentially targets small liposomes (≤ 300 nm)[1].
AH-D peptide (10-500 nM, 48 h) effectively protects primary neuronal cell cultures against cell death induced by the ZIKV MR766 strain[1].
AH-D peptide (10-500 nM, 48 h) inhibits viral replication, protects against ZIKV-induced neuronal cell death, and suppresses replication of the contemporary ZIKV strain HS-2015-BA-01[1].
AH-D peptide shows antiviral activity against ZIKV, Dengue virus, Chikungunya virus, yellow fever virus and Japanese encephalitis virus, with IC50 values of 11.9, 12.5, 35.7, 206 and 136 nM, respectively[1].
AH-D peptide can disrupt T-EXOs and exhibits pH-enhanced membrane disruption (at acidic pH (6.5/6.8) than at neutral pH (7.4)) under acidic conditions relevant to the TME[2].
AH-D peptide (3 μM, 10 min) results in loss of PD-L1EXO-binding capacity to T cells and prevents T-EXO-mediated T cell exhaustion in T-EXOs[2].
AH-D peptide (1-6 h) significantly decreases T cell uptake of T-EXOs[2].
AH-D peptide results significantly greater proliferative potential in T cells, prevents T-EXOs from inhibiting the cytotoxic functions of activated T cells[2].
AH-D peptide has an appreciably higher fraction of gran zyme B (Grz-B)-expressing CD8+ T cells and greater production of pro-inflammatory cytokines, namely interferon-γ (IFN-γ) and tumor necrosis factor-α (TNF-α) [2].
AH-D peptide is mainly related to T-EXO depletion rather than tumouricidal activity, indicating by a negligible effect on the membrane permeability and viability of B16F10 melanoma cells in cytotoxicity test[2].
AH-D peptide effectively reshaped the local TME towards an ICB-sensitive phenotype and inhibited both fibrosis and angiogenesis[2].

AH-D peptide (25 mg/kg ) reduces the viral load in the brain by more than 1 log₁₀ and does not alter the integrity or permeability of the blood-brain barrier in A129-/- mice (before intracranially inoculated p.f.u of the ZIKV HS-2015-BA-01 strain 2×105)[1].
AH-D peptide (7.5 mg/kg, s.c., 6 times) markedly reduced binding capacity of the T-EXOs in PD-L1-bearing T-EXOs isolated from the plasma of B16F10 tumour-bearing mice[2].
AH-D peptide (0-7.5 mg/kg, i.t., 16 days) monotherapy decreases circulating PD-L1EXO levels with a reduction of up to 76% in B16F10 tumour-bearing C57BL/6 mice[2].
AH-D peptide (7.5 mg/kg, i.t., 21 days) significantly diminishes the intratumoural populations of immunosuppressive cells (including CD4
AH-D peptide (7.5 mg/kg, s.c., 4-10 days) exerts no peptide-induced immunogenicity or immunological memory in Wild-type (WT) C57BL/6 mice[2].
AH-D peptide (7.5 mg/kg, i.t.,) demonstrates the superior anti-tumour efficacy when combination with aPD-1 (5 mg/kg, i.p.) in B16F10 tumour-bearing C57BL/6 mice, showing an appreciably larger reductions in tumour volume and weight (80%) but negligible change in tumour growth without aPD-1[2].
AH-D peptide exerts potent anti-metastatic effects by targeting and disrupting T-EXOs, thereby blocking T-EXOs-mediated lung/liver metastasis and premetastatic niche formation in B16F10 tumor-bearing mice[2].

Reduced viral load in the brain, which was associated with a significant decrease in myeloperoxidase (MPO) activity in the brain, indicating diminished leukocyte recruitment.
