Pogostone, a pyranone, is a major constituent of the essential oil preparation called Pogostemonis Herba [1]. Pogostone can alleviate experimental colitis by inhibiting the activity of myeloperoxidase and suppressing the secretion of various inflammatory cytokines, including IFN-γ, IL-12p70, IL-17A and IL-10[2]. Pogostone has been widely used to kill pests and inhibit the development of larvae[3].
In vitro, Pogostone significantly inhibited the viability of HCT116 cells, SW620 cells and MV4-11 cells after 72 hours of treatment, with IC50 values of 18.7µg/ml, 21.39µg/ml and 22.62µg/ml, respectively[4]. Treatment with 90μg/ml Pogostone for 24 hours significantly induced apoptosis in OVCAR-3 cells and promoted the increase in the expression of CASP3 protein[5]. Treatment with 40μM Pogostone for 24 hours significantly reduced the levels of TNF-α-induced inflammatory cytokines in A549 cells, and decreased oxidative stress and cell death[6].
In vivo, Pogostone treatment at a single intravenous dose of 20mg/kg for 6 hours can protect mice from lipopolysaccharide (LPS)-mediated death and alleviate the organ damage induced by LPS in mice[7]. Intraperitoneal injection of Pogostone (25mg/kg/day) for 4 weeks can inhibit bone loss in MDA-MB-231 breast cancer mice and alleviate the damage of bone trabecular structure[8].

Pogostone是一种吡喃酮，是Pogostemonis Herba的精油制剂的主要成分[1]。Pogostone可通过抑制髓过氧化物酶活性并抑制多种炎症细胞因子的分泌，包括IFN-γ、IL-12p70、IL-17A和IL-10，从而减轻实验性结肠炎[2]。Pogostone已被广泛用于杀灭害虫和抑制幼虫发育[3]。
在体外，Pogostone处理72小时显著抑制了HCT116 细胞、SW620细胞和MV4-11细胞的活力，IC50值分别为18.7μg/ml、21.39μg/ml和 22.62μg/ml[4]。使用90μg/ml的Pogostone处理OVCAR-3细胞24小时，显著诱导了细胞凋亡，并促进了CASP3蛋白表达的增加[5]。使用40μM的Pogostone处理A549细胞24小时，显著降低了TNF-α诱导的炎症细胞因子水平，并减少了氧化应激和细胞死亡[6]。
在体内，单次静脉注射20mg/kg剂量的Pogostone，作用6小时，可以保护小鼠免受脂多糖（LPS）介导的死亡，并减轻LPS诱导的小鼠器官损伤[7]。腹腔注射Pogostone（25mg/kg/day）4周，可以抑制MDA-MB-231乳腺癌小鼠的骨丢失，并减轻骨小梁结构的损伤[7]。
