Hyaluronan-IN-1
Based on 1 Customer Validation
Hyaluronan-IN-1 (Pep-1) is a Hyaluronan inhibitor with a Kd value of 1.65 μM. Hyaluronan-IN-1 blocks CD44-dependent cell adhesion. Hyaluronan-IN-1 inhibits cell adhesion to hyaluronan substrates. Hyaluronan-IN-1 suppresses the development of contact hypersensitivity in mice by blocking the homing process of inflammatory cells to the skin. Hyaluronan-IN-1 also inhibits responses during the sensitization phase. Hyaluronan-IN-1 reduces lung metastasis of melanoma and prolongs the survival of mice. Hyaluronan-IN-1 can be used in research related to contact hypersensitivity, chronic skin inflammation, and melanoma.

Biological Activity
Hyaluronan-IN-1 (125 μg/mL; 72 h) does not directly affect the proliferation or the expression of proliferation marker genes in small intestinal organoids derived from wild-type (WT) C57BL/6 mice[1].
Hyaluronan-IN-1 (125I-labeled peptide; 50 μg/mL; 1 h) specifically binds to immobilized HA in a dose-dependent manner via HA-coated paramagnetic bead binding assay, with an apparent affinity constant Kd of 1.65 μM[2].
Hyaluronan-IN-1 (0-500 μg/mL; 2 h) inhibits the binding of soluble HA to BW5147 thymoma cells in a dose-dependent manner, with an inhibition rate of approximately 75% observed at the concentration of 500 μg/mL[2].
Hyaluronan-IN-1 (500 μg/mL; 1 h) potently inhibits CD44-dependent adhesion of B16-F10 melanoma cells to HA-coated substrates[3].
Hyaluronan-IN-1 (500 μg/mL; 1 h) potently inhibits the adhesion of RPMI 7591 melanoma cells to HA-coated substrates[3].
Hyaluronan-IN-1 (500 μg/mL; 1 h) potently inhibits the adhesion of B16-BL6 melanoma cells to HA-coated substrates[3].
Hyaluronan-IN-1 (0-250 μg/mL; 24 h) does not alter the proliferation of B16-F10 melanoma cells in vitro[3].

Hyaluronan-IN-1 (40 mg/kg; i.p.; every other day; 7 days) reduces crypt fission, impairs Lgr5+ stem cell proliferation, suppresses crypt base epithelial proliferation, increases apoptosis, and reduces Paneth cell numbers in wild-type and CD44-/- postnatal mice, but not in TLR4-/- mice, indicating dependence on TLR4 signaling for these postnatal intestinal development effects[1].
Hyaluronan-IN-1 (13.3-40 µg/ear; s.c.; single or two injections; 1-3 days pre-DNFB exposure) inhibits hapten-triggered Langerhans cell migration from the murine epidermis in a dose- and time-dependent manner, with complete inhibition achieved via two 40 µg/ear injections 24 h and 1 h before DNFB exposure[2].
Hyaluronan-IN-1 (40 µg/ear/injection; s.c.; two injections; 24 h and 1 h before sensitization) locally and temporally suppresses the sensitization phase of murine contact hypersensitivity responses, with no induction of long-term unresponsiveness[2].
Hyaluronan-IN-1 (40 µg/ear-1 mg/animal; s.c., i.v., topical; single or two injections; 1-24 h before challenge) inhibits the elicitation phase of acute murine contact hypersensitivity responses, reducing ear swelling, edema, and leukocyte infiltration[2].
Hyaluronan-IN-1 (40 µg/ear/injection; s.c.; injections on days 0, 1, 3, and 5) significantly inhibits murine chronic dermatitis induced by repeated hapten applications[2].
Hyaluronan-IN-1 (500 μg/mouse; i.v.; single co-injection) significantly reduces B16-F10 melanoma lung metastasis incidence and prolongs survival in female C57BL/6 mice, with a 35.1% survival rate at 48 days post-tumor inoculation[3].
