PTD-DBM
Based on 1 Customer Validation
PTD-DBM is a CXXC5-Dvl protein-protein interaction inhibitor and also a Wnt/β-catenin pathway activator. PTD-DBM interferes with the Dvl-binding function of CXXC5, disrupts the negative feedback regulation of the Wnt/β-catenin pathway, induces β-catenin expression and nuclear translocation, and increases the production of type I collagen, α-smooth muscle actin and endothelin-1. PTD-DBM is applicable to studies related to androgenetic alopecia and skin wound healing.

Biological Activity
PTD-DBM (10 μM; 72 h) restores Wnt/β-catenin signaling and proliferation marker expression in PGD2-treated HaCaT cells[1].
PTD-DBM (2-10 μM; 24 h-2 d) activates Wnt/β-catenin signaling and promotes myofibroblast differentiation, collagen production, collagen gel contraction, and cell migration in human dermal fibroblasts in vitro in a concentration-dependent manner, with effects abolished by β-catenin knockdown or bosentan, and synergistically enhanced by co-treatment with Wnt3a[3].
PTD-DBM (2 μM; 2 d) synergistically enhances Wnt/β-catenin activation with Wnt3a in HaCaT keratinocytes, increasing β-catenin expression[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
PTD-DBM (10 mM; topical; daily; 7 to 21 or 25 days post-wounding) restores PGD2-impaired wound-induced hair follicle neogenesis in C57BL/6N mice by reactivating Wnt/β-catenin signaling and regenerative markers, recovering neogenic follicle counts to control levels[1].
PTD-DBM (100 μM; topical; daily; 11 days) alone accelerates cutaneous wound healing and increases collagen production in mice, while PTD-DBM (100 μM + 500 mM VPA; topical; daily; 11 days) co-treatment with VPA synergistically enhances these effects, with no induction of oncogenic markers c-Myc or cyclin D1[3].

Animal Model:C57BL/6N wild-type (7-week-old male; dorsal skin depilation-induced hair cycle synchronization, topical PGD2 exposure-induced hair growth suppression)[1]
-
Dosage:10 mM
-
Administration:topical; every other day; 8 to 12 or 20 days post-depilation
-
Result:Restored PGD2-suppressed hair shaft length to levels comparable to untreated control mice.
Restored nuclear β-catenin fluorescence intensity and PCNA protein expression in skin tissues, which were reduced by PGD2 exposure.
-
Animal Model:C57BL/6N wild-type (3-week-old; full-thickness dorsal skin wound, topical PGD2 exposure-induced hair follicle regeneration suppression)[1]
-
Dosage:10 mM
-
Administration:topical; daily; 7 to 21 or 25 days post-wounding
-
Result:Restored PGD2-suppressed neogenic hair follicle counts (measured via ALP staining) to levels comparable to untreated control mice.
Induced expression of WIHN markers (fgf9, keratin 17), as well as β-catenin and PCNA protein expression in wounded skin tissues, which were reduced by PGD2 exposure.
-
Animal Model:C3H mice (7-week-old male)[3]
-
Dosage:100 μM (single-agent); 100 μM + 500 mM VPA (combination)
-
Administration:topical; daily; 11 days
-
Result:Accelerated cutaneous wound healing to a degree comparable to EGF treatment, reaching ~90% wound closure by day 12.
Increased β-catenin levels in wound tissue, and induced increases in keratin 14, collagen I, PCNA, and endothelin-1 expression in wound keratinocytes and fibroblasts.
Induced significantly greater increases in β-catenin, keratin 14, collagen I, PCNA, endothelin-1, and phosphorylated ERK in wound tissue compared to single-agent treatments or EGF.
