Oxybenzone (Benzophenone 3) 是晒黑和皮肤保护剂中常用的紫外线过滤剂。Oxybenzone用作破坏内分泌的化学物质 (EDCs),并可以穿过胎盘和血脑屏障。 Oxybenzone 损害自噬 (autophagy),改变表观遗传状态并破坏凋亡神经元细胞中的类维生素 X 受体 (retinoid X receptor) 信号传导。
生物活性 | Oxybenzone (Benzophenone 3) is a commonly used UV filter in sun tans and skin protectants. Oxybenzone act as endocrine disrupting chemicals (EDCs) and can pass through the placental and blood-brain barriers. Benzophenone-3 impairsautophagy, alters epigenetic status, and disruptsretinoid X receptorsignaling in apoptotic neuronal cells[1][2][3]. |
体外研究 (In Vitro) | Oxybenzone (Benzophenone 3) (25 μM; 24 hours) decreases the relative RXRβ and RXRγ protein levels by 61 and 56%, respectively and increases the relative RXRα protein level by 49%[3]. Oxybenzone (25-100 μM; 24 hours) induces an increase in caspase-3 levels in primary cultures of mouse neocortical cells at 7 DIV. Oxybenzone-induced apoptosis involves the activation of RXRα signaling and the impairment of RXRβ/RXRγ signaling. Oxybenzone (25 μM; 24 hours) inhibits global DNA methylation as well as reduced HDAC and HAT activities in mouse embryonic neuronal cells[3].
Western Blot Analysis[3] Cell Line: | Mouse neocortical cells at 7 DIV | Concentration: | 25 μM | Incubation Time: | 24 hours | Result: | Exposure to Oxybenzone (25 μM) for 24 h decreased the relative RXRβ and RXRγ protein levels by 61 and 56%, respectively. Treatment with Oxybenzone (25 μM) increased the relative RXRα protein level by 49%. |
