Description

ONO-RS-082 is an inhibitor of phospholipase A (PLA)[1]. ONO-RS-082 inhibits PLA2 with the IC50 of 1.0 μM, but does not inhibit PLC even at 100 μM[2].

In Vitro

ONO-RS-082 (10 μM) prevents P. aeruginosa strain PAO1-induced polymorphonumclear cells (PMNs) transepithelial migration, demonstrating that PLA2 activity is crucial to this process[3].

Cell Viability Assay[3]

Cell Line: A549 lung epithelial cell lines
Concentration: 10 μM
Incubation Time: 2-h pretreatment
Result: Completely blocked HXA3-mediated PAO1-induced PMN transepithelial migration. Largely prevented PAO1-induced PGE2 release.
In Vivo

In vivo long-term activation of KCNK3 by ONO-RS-082 (50 mg/kg/day; preventive treatment, day 0 to day 21) reduces the development of PH in the MCT-PH model[4].
In contrast, in vivo short-term KCNK3 activation by ONO-RS-082 (curative treatment) fails to reduce PH symptoms, which is attributed to the complete loss of KCNK3 expression in MCT-PH rats at days 14 to 21[4].

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

Animal Model: MCT- pulmonary hypertension (PH) rat model[4]
Dosage: 50 mg/kg/day
Administration:
Result: Reduced the development of PH in the MCT-PH model for long-term.

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    90% (20% SBE-β-CD in Saline)

    Solubility: 2.5 mg/mL (6.72 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    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.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: 2.5 mg/mL (6.72 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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:  0.5% CMC-Na/0.1% Tween-80 in Saline water

    Solubility: 10 mg/mL (26.89 mM); Suspended solution; Need ultrasonic

  • Protocol 2

    Add each solvent one by one:  Cremophor EL

    Solubility: 25 mg/mL (67.23 mM); Clear solution; Need ultrasonic

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.
