Key Molecular Targets & Pathway Nodes

WAY-316606's node is SFRP1, an endogenous Wnt antagonist; by blocking SFRP1 it releases Wnt ligands to engage the frizzled/LRP receptor complex and turn on canonical Wnt signaling.

How WAY-316606 Works: Freeing Wnt by Blocking its Inhibitor SFRP1

WAY-316606 binds SFRP1 and out-competes Wnt, releasing Wnt to activate frizzled/LRP and canonical β-catenin signaling

1

SFRP1 Blockade Releases Wnt

SFRP1 is a secreted Wnt antagonist that mops up Wnt ligands. WAY-316606 specifically binds SFRP1 and out-competes Wnt for SFRP1, freeing Wnt proteins to engage the frizzled/LRP receptor complex.

2

Canonical Wnt/β-Catenin Activation

With Wnt free to signal, the destruction complex is inhibited, β-catenin stabilizes and translocates to the nucleus to drive LEF/TCF target-gene transcription. In the human hair bulb this boosts β-catenin activity in pre-cortex keratinocytes and dermal-papilla fibroblasts (EC50 ~0.65 µM).

3

Hair-Shaft Production & Anagen Support

Ex vivo, WAY-316606 enhances hair-shaft production and hair-shaft keratin expression while inhibiting spontaneous follicle regression (catagen). The same Wnt activation also promotes anabolic bone formation, linking it to osteoporosis research.

Frequently Asked Questions (FAQ)

What is WAY-316606 and what does it do?
WAY-316606 (CAS 915759-45-4) is a specific antagonist of SFRP1 (secreted frizzled-related protein 1), an endogenous Wnt inhibitor. By binding SFRP1 it releases Wnt ligands to activate canonical Wnt/β-catenin signaling — boosting hair-shaft production and bone formation. Formula C18H19F3N2O4S2, MW 448.48; Wnt3-reporter EC50 ~0.65 µM.
How is WAY-316606 different from adding Wnt ligand?
Adding Wnt3a supplies ligand directly; WAY-316606 instead blocks the body's own Wnt inhibitor (SFRP1), freeing endogenous Wnt to signal. This acts upstream of the receptor and is tissue-tunable by local SFRP1 levels — distinct from porcupine inhibitors that block Wnt secretion.
What is the mechanism in hair growth?
In the human hair bulb, SFRP1 normally dampens Wnt. WAY-316606 binds SFRP1, allowing Wnt to engage frizzled/LRP, stabilize β-catenin and drive LEF/TCF transcription. Ex vivo this increases hair-shaft keratin expression and production while inhibiting spontaneous follicle regression (catagen) — the basis of its hair-regrowth research.
What are the key experimental readouts?
Readouts include LEF/TCF luciferase reporter activity (EC50 ~0.65 µM), nuclear β-catenin, hair-shaft keratin expression, and ex vivo human scalp explant hair counts / catagen scoring.
How soluble is WAY-316606 and how prepared?
WAY-316606 is highly soluble in DMSO (~90 mg/mL) and ethanol, but water-insoluble. For cell assays dilute DMSO stock into medium (final DMSO <=0.1% v/v); for in vivo use CMC-Na suspensions or validated vehicles. Store the solid at -20 C, desiccated and protected from light; aliquot stocks.
Is QC documentation provided?
Every batch ships with a Certificate of Analysis (COA) including HPLC purity, NMR structural confirmation and MS data. MSDS/SDS and Certificates of Origin are available on request. Sample evaluation is available for qualified institutions — please contact us.
