Titanium tetrafluoride 是一种有效但不稳定的防龋剂。

Rhoifolin (Apigenin 7-O-neohesperidoside) 是从琯溪蜜柚叶子分离的一种黄酮糖苷。它通过 RANKL 诱导的NF-κB 和MAPK 途径改善钛颗粒刺激的骨溶解并减少破骨细胞生成。它通过增强脂联素分泌，胰岛素受体-β的酪氨酸磷酸化和GLUT4易位有助于治疗糖尿病并发症。

H-Arg-Gly-Asp-Cys-OH is a tetrapeptide that contains the arginine-glycine-aspartate (RGD) motif, a sequence that acts as a recognition site for various adhesion proteins.1It inhibits the binding of fibrinogen to endothelial cells and ADP-stimulated platelets with IC50values of 320 and 35 μM, respectively.2Implantation of titanium rods coated with H-Arg-Gly-Asp-Cys-OH increases bone formation in rat femurs.3H-Arg-Gly-Asp-Cys-OH has been conjugated to polyethylenimine to improve gene transfection efficiency.4 1.Park, H.S., Kim, C., and Kang, Y.K.Preferred conformations of RGDX tetrapeptides to inhibit the binding of fibrinogen to plateletsBiopolymers63(5)298-313(2002) 2.Tranqui, L., Andrieux, A., Hudry-Clergeon, G., et al.Differential structural requirements for fibrinogen binding to platelets and to endothelial cellsJ.

Chlorophosphonazo III 是一种同时对钙和镁敏感的试剂。在 pH值为2.2 时，可专门测定钙；在 pH值为7.0 时，可分别测定钙和镁。此外，Chlorophosphonazo III 还适用于分光光度法测定钛、锆、钍、钪、五价锕系元素和镤。
