THPTA(tris-hydroxypropyltriazolylmethylamine) is a water-soluble, veryeffective accelerating ligand for copper-catalyzed Alkyne-Azideclick chemistry reactions (CuAAC). In addition to greatly enhancingthe rate of CuAAC, THPTA minimizes perturbations to thephysiological state of the cells or organisms probed and allows forthe effective bioconjugation with suppressed cell cytotoxicity byfurther lowering Cu loading in the catalyst formulation. Thewater-soluble THPTA ligand further simplifies click chemistry byallowing the entire reaction to be run in water.
THPTA（三羟丙基三唑基甲胺）是一种水溶性、非常有效的加速配体，用于铜催化的炔-叠氮点击化学反应(CuAAC)。 除了大大提高 CuAAC 的速率外，THPTA 还可以大限度地减少了对所探测细胞或生物体生理状态的干扰，并通过降低催化剂配方中的Cu 负载量来实现有效的生物偶联，抑制细胞的细胞毒性。 水溶性 THPTA配体通过允许整个反应在水中进行，简化了点击化学。
