What is the optimal dissolution protocol for Mdivi-1 (HY-15886, MCE)? Below is my dissolution process:

  • First, weigh out 12.5 mg of Mdivi-1 powder and add 500 µL of DMSO. Wait until fully dissolved to obtain a clear DMSO stock solution.
  • Next, prepare a 20% SBE-β-CD in saline solution: Weigh 20 mg of SBE-β-CD powder. Add 10 mL of saline and stir until completely dissolved and clear.
  • Then, take 500 µL of the DMSO stock solution and slowly add it to 4500 µL of the 20% SBE-β-CD in saline solution.
  • During the addition of the 4500 µL 20% SBE-β-CD solution, precipitation of the drug was observed.
  • I tried heating at 37°C and sonication, but the solution did not become clear.
