The lead compound was then tested in a series of animal models of ALI. Initial evaluation employed the lipopolysaccharide (LPS) induced lung injury model, followed by models involving TRPV4 overexpression in alveolar macrophages, as well as models featuring TRPV4 hyperactivation. These models were strategically chosen to replicate key pathological features of clinical ALI.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Our investigation revealed that administration of the lead derivative CS-85(\n                      <jats:bold>4j<\/jats:bold>\n                      ) demonstrated significant protective effects in a mouse model of ALI. CS-85 effectively prevented lung edema and maintained the integrity of pulmonary vascular barrier. Notably, it inhibited neutrophil influx into the lung, reduced proinflammatory cytokine production, and mitigated associated pathological changes. In additional relevant preclinical\n                      <jats:italic>in vivo<\/jats:italic>\n                      models, we further investigated how TRPV4 hyperactivation via pharmacological stimulation and overexpression in alveolar macrophages through liposome-mediated gene delivery exacerbated key features of ALI. CS-85 effectively reduced this exaggerated lung inflammation and alleviated the ALI features. In exploring the downstream mechanisms of CS-85, we found that its pharmacological efficacy is mediated through modulation of the NLRP3-caspase-1, NFAT, and NF-\u0138B signaling pathways, all of which are crucial inflammatory cascades.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>We identified CS-85 as a potent and promising TRPV4 inhibitor that demonstrates strong preclinical efficacy in mitigating ALI by preserving vascular integrity and modulating key inflammatory signaling pathways.
