UK‑78282 hydrochloride blocks Kv1.3 channel function in various cell models. Under acute administration conditions, this compound blocks native Kv1.3 channels in human peripheral blood T lymphoblasts (IC50 = 202 nM), recombinant Kv1.3 channels in L929 cells (IC50 = 280 nM), and Kv1.3 channels in RBL cells (IC50 = 333 nM); it inhibits Kv1.3-mediated 86Rb efflux in human T cells (IC50 = 0.4 μM); and it inhibits the binding of 125I‑ChTX to Kv1.3 expressed in HeLa cells (IC50 = 0.7 μM)[1].
UK‑78282 hydrochloride produces use-dependent block of Kv1.3 channels in human peripheral blood T lymphoblasts; the longer the duration of depolarizing pulses, the faster the establishment of steady-state block. Maintaining the holding potential at -50 mV to increase the proportion of C-type inactivated channels enhances the blocking efficacy of this compound[1].
UK-78282 hydrochloride binds to an internal site of the Kv1.3 channel in human peripheral blood T lymphoblasts. This site overlaps with the binding site of verapamil, but does not overlap with the binding sites of extracellular ChTX or intracellular TEA[1].
UK-78282 hydrochloride exhibits selectivity for Kv1.3 and Kv1.4 channels over other Kv family channels, with negligible activity on T cell KCa channels at concentrations up to 30 μM[1].
UK‑78282 (100 nM; ≥2 min) hydrochloride selectively inhibits action potential firing only in striatal projection neurons of the nucleus accumbens shell in low-motivation (lowS) rats, and slows the inactivation of their A-type potassium currents; this compound reduces the amplitude of A-type potassium currents in such neurons across three groups of rats, namely low-motivation (lowS), high-motivation (highS), and moderate-motivation (midS) rats[1].
UK‑78282 hydrochloride inhibits PHA-induced proliferation of purified human peripheral blood T cells (IC50 = 2.0 μM) by acting on the late G1/early S phase of the cell cycle; it also suppresses PHA-stimulated IL‑2 production (IC50 = 2.9 μM)[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (5.36 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
