YS-01
YS-01 is an inhibitor of pendrin (SLC26A4) with pulmonary protective activity. YS-01 inhibits pendrin-mediated anion exchange activity, reduces pendrin expression, and suppresses the activation of NF-κB and the production of proinflammatory cytokines. YS-01 alleviates lipopolysaccharide-induced and ventilator-induced lung injury. YS-01 attenuates ovalbumin-induced airway hyperresponsiveness, inflammatory infiltration, epithelial thickening and goblet cell hyperplasia, and reduces eosinophil and neutrophil counts. YS-01 decreases MUC5AC transcription levels induced by IL-4, reverses the reduction of airway surface liquid volume, and inhibits the increase of apical SCN− concentration in epithelial cells. YS-01 can be used in studies related to lung injury and allergic asthma.

Biological Activity
YS-01 potently inhibits pendrin-mediated Cl−/SCN− exchange activity in pendrin-transfected human alveolar epithelial cells, with an IC50 of 4.7 μM; it significantly inhibits LPS-induced increase in apical SCN− concentration in human nasal epithelial cells[1].
YS-01 (0-100 μM; 10 minutes at 37°C) potently and selectively inhibits human and mouse pendrin-mediated anion exchange across multiple anion pairs in CHO-K1 cells, and shows no activity against a variety of related ion channels and transporters at relevant concentrations[3].
YS-01 (0-100 μM) inhibits IL-4-induced pendrin-mediated Cl−/HCO3− exchange activity in primary human nasal epithelial cells in a dose-dependent manner, with significant inhibition observed at concentrations as low as 3 μM[3].
YS-01 (30 μM; 24-48 h) reduces the functional expression of IL-4-induced pendrin protein levels in primary human nasal epithelial cells (without affecting mRNA levels) and exerts no effect on related ion channels[3].
YS-01 (30 μM; 30 min) inhibits IL-4-induced transepithelial SCN− transport in primary human nasal epithelial cells cultured at an air-liquid interface[3].
YS-01 reduces IL-4-induced MUC5AC expression and IL-4/IL-13-induced goblet cell hyperplasia in primary human nasal epithelial cells; it rescues the reduction of airway surface liquid volume induced by IL-4 and IL-13 in primary human nasal epithelial cells expressing wild-type pendrin[3].
YS-01 inhibits IL-4-induced activation of NF-κB in primary human nasal epithelial cells[3].

Cell Line:primary human nasal epithelial cells
-
Concentration:30 μM
-
Incubation Time:24 h, 48 h
-
Result:Reduced IL-4-induced pendrin functional expression at the protein level (not mRNA) in primary human nasal epithelial cells after 24 or 48 hours of treatment, without affecting related ion channels.
YS-01 (10 mg/kg; i.p.; single dose) significantly attenuates lung inflammation and injury in supine HTV-ventilated pendrin wild-type 129SVEV mice, including reducing TNF-α and MIP-2 levels by 83% and 81% respectively[2].
YS-01 (10 mg/kg; i.p.) significantly reduces OVA-induced airway hyperresponsiveness, airway inflammation, and goblet cell hyperplasia in a murine allergic asthma model without affecting OVA-specific IgE levels[3].
YS-01 provides therapeutic benefits by reducing airway hyperresponsiveness and goblet cell hyperplasia in mice with established allergic asthma[3].

Animal Model:C57BL/6J (male, 8-10 weeks old, 20-24 g, intranasal LPS-induced acute lung injury)[1]
-
Dosage:10 mg/kg (pre-treatment; post-treatment)
-
Administration:i.p.; single dose (1 hour before LPS instillation for pre-treatment); two doses (6 and 12 hours after LPS instillation for post-treatment)
-
Result:Reduced LPS-evoked pulmonary damage by lowering BALF cell count, protein content and lung injury scores.
Inhibited NF-κB signaling, downregulated pendrin expression and decreased pulmonary pro-inflammatory cytokine production (IL-1β, MIP-2, IL-6, TNF-α) upon LPS stimulation.
Abolished such pulmonary protective effects following co-administration with intranasal NaSCN, with all injury indicators returning to the levels of the LPS-alone group.

Animal Model:129SVEV mice (pendrin wild-type, weight 20-25 g, age 6-8 weeks)[2]
-
Dosage:10 mg/kg
-
Administration:i.p.; single dose
-
Result:Decreased total cell numbers in BALF and alleviated lung injury.
Dropped lung TNF‑α and MIP‑2 contents to 1.03 pg/mL and 110.28 pg/mL respectively, corresponding to 83% and 81% reductions.
Downregulated pendrin expression within lung tissues.

-
Result:Inhibited pulmonary NF-κB activation in OVA-challenged mice.
Co-administration with NaSCN abolished this inhibitory action against NF-κB activation.
