YHV98-4 specifically inhibits Hv1 with a half-maximal inhibitory concentration of 1 μM, without inhibiting other ion channels[1].
YHV98-4 (0.1-10 μM) potently inhibits the Hv1 channel expressed in HEK-293T cells, with an IC50 of 0.7 μM[3].
YHV98-4 (20 μM) exhibits no inhibitory activity against hERG, KCNQ2, BK, Nav1.7, TRPV1, TRPA1 or VRAC channels, demonstrating high selectivity for Hv1[3].
YHV98-4 (20 μM) alleviates mitochondrial oxidative stress, restores energy metabolism, rescues defects in mitophagy and autophagy, reduces mtDNA leakage, and enhances the phagocytosis of BV2 microglia stimulated by PHF[2].

Animal Model:3×Tg (male and female, 7 months old at study initiation, genetic model with both Aβ and tau pathology)[2]
-
Dosage:10 mg/kg
-
Administration:i.p.; daily; 30 days
-
Result:Restored microglial morphological homeostasis, including increased segment branch number, segment terminal number, microglial area, and microglial volume compared to untreated 3×Tg mice.
Reduced hippocampal Hv1 intensity in Iba1-positive microglia.
Decreased hippocampal AT8 coverage and AT8 intensity (hyperphosphorylated tau marker), with no significant effect on 4G8-positive Aβ area.
Reduced hippocampal reactive oxygen species (ROS) levels measured by DHE fluorescence intensity.
Restored neuronal health with increased hippocampal NeuN intensity and MAP2 coverage.
Improved cognitive function as measured by reduced escape latency in MWM training trials, increased platform crossings and time spent in the target quadrant during MWM probe trials, higher discrimination index in the NOR test, and higher percentage of spontaneous alternation in the Y-maze test.

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: ≥ 5 mg/mL (15.02 mM); Suspended solution
This protocol yields a suspended solution of ≥ 5 mg/mL (saturation unknown). Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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.
