XW-17
XW-17 is a PARP14 inhibitor with an IC50 of 3.03 nM and selectivity over other PARP family members.XW-17 suppresses PARP14-mediated mono-ADP-ribosylation, engages and stabilizes endogenous PARP14 protein.XW-17 attenuates skin lesions and decreases expression of IL-4, IL-13, IgE, and IL-17A in an atopic dermatitis-like mouse model.XW-17 can be used for the research of atopic dermatitis.

PARP14 |
XW-17 (1 h) potently and selectively inhibits purified PARP14 enzyme activity with an IC50 of 3.03 nM, showing a selectivity index exceeding 9900 over PARP1[1].
XW-17 shows excellent metabolic stability across rat plasma, mouse liver microsomes, rat liver microsomes, and human liver microsomes, with T1/2 values greater than 240 min in all tested systems[1].
XW-17 (5 μM; 2 h) exhibits satisfactory membrane permeability and low efflux in MDCK and Caco-2 cell models, with Papp A→B values of 16.32 × 10-6 cm/s and 20.49 × 10-6 cm/s, respectively[1].
XW-17 (0.001-3 μM; unspecified duration) engages and stabilizes endogenous PARP14 in IFN-γ-stimulated CFPAC-1 cells with an EC50 of 59.5 nM[1].
XW-17 (0.01-1 μM; 6 h pretreatment, 24 h IFN-γ stimulation) potently inhibits PARP14-mediated MARylation in a concentration-dependent manner in IFN-γ-stimulated CFPAC-1 and RAW264.7 cells[1].
XW-17 (up to at least 30 μM; 72 h) shows no significant cytotoxicity toward MCF-10A and AML-12 cells, with IC50 values greater than 30 μM[1].
XW-17 (5-30 μM) has low hERG potassium channel inhibitory activity, with 3.15% inhibition at 5 μM and 5.56% inhibition at 30 μM, indicating low cardiotoxicity risk[1].

Animal Model:BALB/c (male, 18−22 g, DNCB-induced atopic dermatitis)[1]
-
Dosage:25 mg/kg; 50 mg/kg; 100 mg/kg
-
Administration:i.p.; twice daily; 11 days
-
Result:Significantly reduced dermatitis score compared to model group at 25 mg/kg (P < 0.05), 50 mg/kg (P < 0.01), and 100 mg/kg (P < 0.001).
Achieved lower dermatitis score than positive controls RBN-3143 and Upadacitinib at 100 mg/kg.
Dose-dependently reduced histopathological abnormalities in dorsal skin, with 100 mg/kg dose achieving lowest histological score and outperforming Upadacitinib.
Significantly reduced protein levels of IL-4, IL-13, IL-17A in skin homogenates and serum IgE at 50 mg/kg and 100 mg/kg, with most pronounced inhibition at 100 mg/kg.
Dose-dependently suppressed mRNA levels of IL-31, TSLP, and GATA3 in dorsal skin.
Showed no significant effect on Th1 pathway-related cytokines (TNF-α, IL-6, IL-1β) at any dose.
Caused no significant body weight loss or histological abnormalities in major organs (heart, liver, spleen, lung, kidney).
