Biacetyl monoxime
Based on 1 Customer Validation
Biacetyl monoxime (Diacetyl monoxime), a myosin ATPase inhibitor, is a skeletal and cardiac muscle contraction inhibitor. Biacetyl monoxime is also a well-characterized non-competitive inhibitor of chemical and motile activity of skeletal muscle myosin-II. Biacetyl monoxime induces sarcoplasmic reticulum Ca2+ release.

Biological Activity
Biacetyl monoxime (Diacetyl monoxime) (50 mM, 6 and 48 h) decreases cellulase secretion in C. cinerea[1].
Biacetyl monoxime (50 mM, 2 and 4 h) disrupts the localization of the Golgi apparatus, but not that of the endoplasmic reticulum[1].
Biacetyl monoxime (0-30 mM) induces SR Ca2+ release (no efflux inhibitors) in a concentration-dependent manner, with a maximal reduction of 72% of SR Ca2+ at pCa 6.0[2].
Biacetyl monoxime acts as a chemical phosphatase, which has led to speculation that dephosphorylation of key Ca2+ channel proteins may be involved in its inhibition of contraction[2].
Biacetyl monoxime does not inhibit the ATPase activity of two different myosin-I isoforms, myosin-V, or myosin-VI[3].
Biacetyl monoxime (0-50 mM) suppresses L-type Ca2+ current of single cardiac myocytes isolated from SHR and WKY rats[4].
Biacetyl monoxime significantly reduces the duration of both spontaneous and electrically stimulated action potentials of cultured neonatal rat cardiomyocytes[4].

Biacetyl monoxime (0-205 mg/kg; i.p.; once) shows anticonvulsant effect against Picrotoxin (HY-101391)-induced convulsions[5].

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: ≥ 2.08 mg/mL (20.57 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (20.57 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.
