一般建议为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。

资料参考

Gallein is a small inhibitor of G protein βγ (Gβγ) subunit signalling [1].

Gβγ subunits are central participants in G protein-coupled receptor (GPCR) signaling pathways. Gβγ subunits interact with receptors, G protein α subunits and downstream targets to coordinate multiple, different GPCR functions [2].

In spheroids made by LNCaP cells and grown in collagen gels, gallein at 10 μM was able to significantly counteract β-ionone-induced LNCaP cell invasiveness [1]. In human monocyte-derived macrophages, gallein effectively inhibited M1 polarization and promoted M2 polarization [3].

In castrated male NSG mice carrying subcutaneous injected LNCaP cells, intraperitoneal injection of gallein (5 mg/kg/day) inhibited β-ionone-mediated metastasis spread [1]. In a rat model of autoimmune myocarditis, gallein (10 mg/kg/day, p.o., for 21 days) effectively improved survival and cardiac function, suppressed cardiac remodeling, and further attenuated myocardial protein expression of G protein-coupled receptor kinase 2 (GRK2) as well as high mobility group box 1 (HMGB1) and its cascade signaling proteins [3].
