In Vitro

Pinacidil (0-2 mM, 48 h) monohydrate induces DNA fragmentation in a dose-dependent manner and is prominent at 1 mM in HepG2 cells[2].
Pinacidil (1-2 mM, 36 h) monohydrate induces loss of phospholipid asymmetry, resulting in appearance of phosphatidylserine on the outer layer of the plasma membrane detected by annexin-V binding in HepG2 cells[2].
Pinacidil (1 mM, 0-48 h) monohydrate induces apoptosis in a time-related manner without involvement of KATP channels in HepG2 cells[2].
Pinacidil (1 mM) monohydrate induces a rapid and sustained increase in [K+] and [Ca2+] in HepG2 cells[2].
Pinacidil (1 mM, 0-60 min) monohydrate induces Ca2+ influx through activation of the reverse mode of Na+/Ca2+ exchanger which is achieved by increased [Na+]i attributed to activation of NKCC[2].
Pinacidil (1-100 μM and 0.3-30 μM, 30 min) monohydrate produces a concentration-dependent inhibition of responses to noradrenaline in rat aorta and portal vein[3].
Pinacidil (1-100 μM) monohydrate produces a concentration-dependent inhibition of responses to KCl (10-80 mmol/L) in rat aorta[3].
Pinacidil (0.3-30 μM) monohydrate produces an inhibition of responses to KCl (5-80 mmol/L) and the –log IC50 against KCl (20 mmol/L) contraction was 6.2[3].
Pinacidil (0.1-100 μM) monohydrate is capable of producing almost total relaxation of tissue, and remains unaffected in the presence of Apamin (HY-P0256) (0.1 μM) in guinea-pig trachea[3].
Pinacidil (0.3-10 μM, 4.5-7 min) monohydrate abolishes spontaneous multispike complexes and mechanical activity, and results in a concentration-dependent hyperpolarization in rat portal vein[3].
Pinacidil (0.3-30 μM, 10-35 min) monohydrate produces a greater and longer lasting increase in 86Rb exchange in the aorta than in the portal vein[3].

In Vivo

Pinacidil (3-30 μg, i.c.v., one single dose) monohydrate increases tail-flick latency dose-dependently in non- diabetic (ED50 = 16.1) and diabetic mice (ED50 = 22.3)[4].
Pinacidil (10-100 μg, i.t., one single dose) monohydrate produces dose-dependent and significant antinociception in diabetic mice and a dose of 100 μg results no significant antinociception in non-diabetic mice (ED50 = 18.5), whereas ED50 for diabetic mice is 95.6[4].
Pinacidil (30 μg, i.c.v., one single dose) monohydrate is not affected by the pretreatment of β-Funaltrexamine (HY-101318) (20 and 40 mg/kg, s.c.) on the antinociception in diabetic mice[4].
Pinacidil (30 μg, i.t., one single dose) monohydrate has a dose-dependently reduction of antinociceptive effect with β-Funaltrexamine (20 and 40 mg/kg, s.c.), and is antagonized by the pretreatment with 7-Benzylidenenaltrexon (HY-169867) (0.3 mg/kg), Naltriben (0.3 mg/kg) (HY-133717), or nor-Binaltorphimine (20 mg/kg, s.c.) (HY-117040) in diabetic mice[4].

In Vivo:

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.

  • Protocol 1

    Add each solvent one by one:  10% EtOH    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (9.49 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 EtOH 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.
  • Protocol 2

    Add each solvent one by one:  10% EtOH    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (9.49 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 EtOH stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
