Description
MR 409, a selective growth hormone-releasing hormone (GHRH) agonist, exhibits notable neuroprotective properties by augmenting endogenous neurogenesis in cerebral ischemic mice and demonstrates the ability to inhibit in vivo lung cancer growth [1] [2] [3] [4].
In vitro
One week after myocardial infarction (MI), MR 409 (MR-409) significantly diminishes plasma concentrations of IL-2, IL-6, IL-10, and TNF-α compared to placebo [1]. At a concentration of 1 μM, MR-409 attenuates p53 expression in bovine pulmonary arterial endothelial cells (BPAECs) and activates JAK2, STAT3, and ERK1/2 signaling pathways [2]. Furthermore, MR-409 (1 and 5 μM) reduces lipopolysaccharide (LPS)-induced PGE2 and 8-iso-PGF2α production in a dose-responsive manner, whereas it decreases LPS-induced lactate dehydrogenase (LDH) activity and nitrite levels independently of dose variation [3]. Similarly, gene expression of COX-2, NF-κB, and iNOS in colon specimens induced by LPS is mitigated by MR-409 at concentrations of 1 and 5 μM, again without showing dose-dependency [3]. Additionally, MR-409 stimulates endogenous neurogenesis and counteracts tMCAO-induced neuroplasticity deficits, along with promoting proliferation and reducing apoptosis in neural stem cells subjected to oxygen and glucose deprivation-reperfusion [4].
In vivo
MR 409 (MR-409) suppresses lung cancer growth in vivo when xenografted into nude mice [3]. Additionally, when administered subcutaneously at a dose of 5 μg daily for four weeks, MR 409 diminishes the nociceptive response in mice [3].

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:
TargetMol | Animal experiments For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, TargetMol | Animal experiments and a total of 10 animals are to be administered, using a formulation of TargetMol | reagent 10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.
Stock Solution Preparation:

Dissolve 2 mg of the compound in 100 μL DMSOTargetMol | reagent to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.

Preparation of the In Vivo Formulation:

1) Add 100 μL of the DMSOTargetMol | reagent stock solution to 400 μL PEG300TargetMol | reagent and mix thoroughly until the solution becomes clear.

2) Add 50 μL Tween 80 and mix well until fully clarified.

3) Add 450 μL Saline,PBS or ddH2OTargetMol | reagent and mix thoroughly until a homogeneous solution is obtained.

This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.
All co-solvents required for this protocol, includingDMSO, PEG300/PEG400, Tween 80, SBE-β-CD, and Corn oil, are available for purchase on the TargetMol website.
