MK-761 TFA
Based on 1 Customer Validation
MK-761 TFA is an orally effective β2-adrenergic receptor antagonist. MK-761 TFA attenuates positive inotropic effects, reduces arterial pressure, enhances the contractility of papillary muscles in cat hearts, and exerts effects mediated by catecholamine release. MK-761 TFA can be used in the research of hypertension.

Biological Activity
MK-761 (0.125-2.0 μg/mL; 30 min) TFA enhances the contractility of isolated cat papillary muscles in a dose-dependent manner, and this positive inotropic effect is significantly inhibited by pretreatment with Timolol (HY-17494)[1].
MK-761 (0.03-1.0 μg/mL; 30 min) TFA blocks the positive inotropic effect of isoprenaline (HY-B0468) on isolated cat papillary muscles[1].

-
Animal Model:Wistar-Okamoto spontaneously hypertensive (SH) (male, 30-40 weeks, 290-350 g)[1]
-
Dosage:1.25 mg/kg (no pretreatment); 0.312 mg/kg (Timolol pretreatment)
-
Administration:p.o.; single dose
-
Result:Lowered mean arterial pressure in SH rats, with maximal effect reached at 1 hour after administration of 1.25 mg/kg p.o.
Showed no significant difference in heart rate changes compared to vehicle control.
Exhibited an antihypertensive effect at 0.312 mg/kg p.o. that was not antagonized by pretreatment with 8 mg/kg p.o. timolol.
Had a relative antihypertensive potency of 3.4 (relative to hydralazine, potency = 1) with 95% confidence limits of 1.8 and 7.3.

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 (6.88 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (6.88 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 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.
