cesium

Cesium chloride (CsCl) 是一种钾通道抑制剂，可以防止 Alloxan 引起的 Na+转运减少。Cesium chloride 可以诱发心律失常。

Cesiumiodide (Cesiumiodidewhitextl) 可作为生命科学研究中的生物材料或有机化合物使用。

Tetranactin is a macrotetrolide and a monovalent cation ionophore that has been found in S. aureus and has antibacterial, insecticidal, and mitogenic activities. It exhibits an equilibrium permeability ratio 1,000-fold greater for lithium than sodium or cesium ions accross bilayer membranes at low voltages. Tetranactin inhibits the growth of Gram-positive bacteria and C. miyabeanus and R. solani fungi when used at concentrations less than 0.9 μg/ml. Tetranactin (0.5-1.5 μg per insect) dose-dependently increases the mortality of adult C. chinensis weevils up to 100% and has mitogenic activity against T. telarius when sprayed onto plants with an LC50 value of 9.2 μg/ml. It reduces IL-1β- and cAMP-induced secretion of phospholipase A2 (PLA2) from rat mesangial cells (IC50s = 43 and 33 nM, respectively). Tetranactin (50 ng/ml) suppresses the proliferation of human T lymphocytes induced by allogeneic cells and IL-2 and supresses the generation of cytotoxic T lymphocytes in mixed lymphocyte cultures. In vivo, tetranactin (10 mg/animal per day) completely inhibits the formation of experimental autoimmune uveoretinitis (EAU) in rats.

Prussian blue soluble 作为一种有效的吸附剂，被广泛应用于铯或铊离子中毒的解毒治疗中。此外，Prussian blue soluble 还展现出抗癌和抗菌的特性。它也常用作光声及磁共振成像 (MRI) 的造影剂。
