Growth hormone (GH) modulates normal growth and metabolism, and its effects are counteracted by somatostatin (SST). Pasireotide (PAS), an FDA-approved synthetic derivative of somatostatin, acts via binding to multiple somatostatin receptors, and it is commonly used in conditions unresponsive to first-generation somatostatin analogs. Herein we explore the potential of PAS to protect against endothelial dysfunction induced by lipopolysaccharides (LPS). This is a bacterial toxin which causes inflammation and compromises endothelial barrier integrity. Endothelial cells were treated with PAS before LPS exposure to evaluate the corresponding effects on cell viability, inflammation, and barrier function. Since PAS suppressed LPS-triggered endothelial injury, it is suggested that this compound could be repurposed for endothelium-dependent disorder treatment.
生长激素(GH)调节正常生长和代谢,其作用会被生长抑素(SST)抵消。帕西瑞肽(PAS)是一种经美国食品药品监督管理局(FDA)批准的生长抑素合成衍生物,通过与多种生长抑素受体结合发挥作用,常用于对第一代生长抑素类似物无反应的病症。在此,我们探讨帕西瑞肽预防脂多糖(LPS)诱导的内皮功能障碍的潜力。脂多糖是一种细菌毒素,可引发炎症并损害内皮屏障完整性。在内皮细胞暴露于脂多糖之前用帕西瑞肽进行处理,以评估其对细胞活力、炎症和屏障功能的相应影响。由于帕西瑞肽可抑制脂多糖引发的内皮损伤,因此提示该化合物可重新用于治疗内皮依赖性疾病。
