Bendazol is an orally effective antihypertensive agent. Bendazol acts directly on vascular smooth muscle to dilate blood vessels and reduce peripheral resistance, thereby improving blood circulation. Bendazol significantly inhibits the development of myopia in rabbit models. Bendazol can regulate kidney function by increasing the activity of NO synthase in the rat model of nephrogenic hypertension. In addition, Bendazol has an effect on sexual behavior and spermatogenesis in male rats.

In Vivo

Bendazol (1%; Eye drops; Four times daily for 6 weeks) significantly inhibits the development of myopia and down-regulates the expression of HIF-1α in experimental myopia rabbit models^[1].
Bendazol (0.1 mg/kg; Intraperitoneal injection; 2 weeks) regulates kidney function by increasing the activity of NO synthase in the rat model of nephrogenic hypertension^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:	New Zealand white rabbits aged 3 weeks old with experimental myopia^[1]
Dosage:	1%
Administration:	Eye drops; Four times daily for 6 weeks
Result:	Inhibited the progression of form-deprivation myopia. Suppressed the upregulation of HIF-1α.

Animal Model:	Paraformaldehyde (HY-Y0333) treated mature random-bred male rats (250-280 g)^[2]
Dosage:	0.1 mg/kg
Administration:	Intraperitoneal injection (i.p.); 2 weeks
Result:	Remained NADPH diaphorase activity in PT epitheliocytes near the control level throughout the experiment; Gradually increased NADPH diaphorase activity in DT epitheliocytes to the control level throughout the experiment. Enhanced NADPH diaphorase activity and maintained it elevated in renal glomeruli throughout the experiment; Increased NADPH diaphorase in the collecting tubules, but thereupon it declined to the control level at the end of experimental. Insignificant enhanced of NOS activity in PT epitheliocytes observed on postinjection week 1 can somewhat contribute to upregulation of natriuresis and diuresis.

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% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (12.00 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.

Working solution concentration: mg/mL

Method for preparing stock solution: mg drug dissolved in μL DMSO (Stock solution concentration: mg/mL).

The concentration of the stock solution you require exceeds the measured solubility. The following solution is for reference only. If necessary, please contact MedChemExpress (MCE).

Method for preparing in vivo working solution for animal experiments: Take μL DMSO stock solution, add μL . μL , mix evenly, next add μL Tween 80, mix evenly, then add μL Saline.

If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.

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.
