General description
硫酸镁七水合物是硫酸镁的水合盐。它在无水状态下具有吸湿性。它可以用作亲水性添加剂和有机合成中的催化剂。
Application
七水合硫酸镁可用于：
- 作为室温下邻苯二胺和1,2-二羰基化合物缩合反应的有效催化剂。
- 作为催化剂，广泛用于芳香族醛、苯、脂肪族和芳香族伯胺及乙酸铵合成三/四取代咪唑。
- 通过与十水硼酸钠相互作用制备不同组成的无定形硼酸镁。
七水合硫酸镁可用作催化剂，用于使邻苯二胺与1,2-二羰基化合物缩合形成吩嗪和喹喔啉衍生物。它也可与三氟甲磺酸铟 (Ⅲ) 一起用作催化剂，用于合成三/四取代咪唑。

The pro-longevity enzyme SIRT6 regulates various metabolic pathways. Gene expression analyses in SIRT6 heterozygotic mice identify significant decreases in PPARα signaling, known to regulate multiple metabolic pathways. SIRT6 binds PPARα and its response element within promoter regions and activates gene transcription.
