Marmin
Based on 1 Customer Validation
Marmin is a histamine receptor inhibitor and tracheal smooth muscle relaxant. Marmin antagonizes histamine- and methacholine-induced contraction of tracheal smooth muscle. Marmin inhibits histamine release from mast cells, and also blocks extracellular calcium influx via voltage-dependent calcium channels as well as calcium release from intracellular calcium stores, thereby effectively inhibiting calcium-mediated smooth muscle contraction. Marmin slightly enhances the relaxant effect of isoprenaline, and induces epithelial-dependent tracheal smooth muscle relaxation independent of nitric oxide, cGMP or β2-adrenergic pathways through the release of prostaglandin E2.

Marmin (10-100 μM; 10 min) competitively inhibits histamine-induced contraction of guinea pig-isolated tracheal smooth muscle, reducing histamine potency with pD2 values of 5.83 at 10 μM and 4.95 at 100 μM[1].
Marmin (10-100 μM; 10 min) inhibits metacholine-induced contraction of guinea pig-isolated tracheal smooth muscle, reducing metacholine potency with pD2 values of 5.71 at 10 μM and 5.59 at 100 μM[1].
Marmin (100 μM; 10 min) abrogates Compound 48/80-induced contraction of guinea pig-isolated tracheal smooth muscle[1].
Marmin (100 μM; 10 min) mildly potentiates isoprenaline-induced relaxation of guinea pig-isolated tracheal smooth muscle, increasing isoprenaline potency with a pD2 value of 6.38, while marmin (10 μM; 10 min) has no significant effect, with an isoprenaline pD2 value of 6.16[1].
Marmin (100 μM; 10 min) inhibits CaCl2-induced contraction of guinea pig-isolated tracheal smooth muscle in Ca2+-free Krebs solution[1].
Marmin (100 μM; 10 min) obviously inhibits intracellular Ca2+ release-induced contraction and mildly inhibits voltage-dependent Ca2+ channel-mediated Ca2+ influx-induced contraction in guinea pig-isolated tracheal smooth muscle in Ca2+-free Krebs solution[1].

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 (7.52 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.
