CX-Se13
CX-Se13 is an orally active pulmonary fibrosis inhibitor with anti-inflammatory and antioxidant activities. CX-Se13 regulates the Keap1/Nrf2/HO-1/NQO1, YAP/TAZ-TEAD, NF-κB p65 and TGF-β/Smads signaling pathways. CX-Se13 activates the cellular antioxidant defense system, restores redox balance, alleviates inflammatory responses, reduces collagen deposition, decreases pro-inflammatory cytokine levels and inhibits pathological progression. CX-Se13 can be used in studies related to pulmonary fibrosis.

CX-Se13 (compound E13) exhibits anti-inflammatory, antioxidant and antifibrotic activities, with an NO IC50 of 3.4 μM, an ROS inhibition rate of 93.4%, an α-SMA inhibition rate of 85.4%, and a cytotoxicity IC50 >100 μM[1].
CX-Se13 (1.25-20.0 μM) inhibits LPS-induced production of proinflammatory cytokines in RAW264.7 macrophages in vitro in a concentration-dependent manner[1].
CX-Se13 (10.0 μM) ameliorates TGF-β1-induced oxidative stress in MRC-5 fibroblasts by reducing ROS and MDA levels and increasing SOD levels[1].
CX-Se13 (0.625-40 μM; 24-72 h) inhibits TGF-β1-induced proliferation of MRC-5 fibroblasts in a time-dependent manner, with its IC50 value decreasing from 3.4 μM at 24 h to 0.9 μM at 72 h[1].
CX-Se13 (2.5-10.0 μM; 24 h) inhibits TGF-β1-induced migration of MRC-5 fibroblasts [1].
CX-Se13 (2.5-10.0 μM) reduces the expression of fibrosis markers in TGF-β1-induced MRC-5 fibroblasts in a concentration-dependent manner in vitro, and its antifibrotic activity is superior to that of PFD at equivalent doses; it activates the TGF-β1-induced Keap1/Nrf2/HO-1 pathway in MRC-5 fibroblasts and restores cellular redox balance[1].
CX-Se13 exhibits moderate permeability in Caco-2 cells, with a Papp value of 1.8 × 10-6 cm/s[1].
CX-Se13 directly binds to intracellular ROCK2 in living cells[1].
CX-Se13 (2.5-10.0 μM) dose-dependently inhibits the TGF-β1-induced NF-κB p65/IκBα pathway in MRC-5 fibroblasts in vitro. It also inhibits the TGF-β1/Smad pathway and reduces the expression of proteins related to collagen deposition, as well as suppresses the YAP/TAZ-TEAD pathway, thereby inhibiting fibroblast activation and extracellular matrix deposition[1].

CX-Se13 (10-40 mg/kg; intragastric administration once daily for 14 consecutive days starting from day 7 of modeling) dose-dependently ameliorates systemic and respiratory abnormalities in mice with bleomycin (HY-108345)-induced pulmonary fibrosis, alleviates pulmonary hemorrhage, alveolar injury, collagen deposition and inflammatory infiltration, and downregulates fibrosis markers and inflammatory cytokines; it also activates the Nrf2 antioxidant pathway and inhibits the pro-inflammatory and pro-fibrotic NF-κB, TGF-β/Smad, and YAP/TAZ pathways[1].
