Descripciòn

Bosentan hydrate is a competitive and dual antagonist of endothelin-1 (ET) for the ET_A and ET_B receptors with K_i of 4.7 nM and 95 nM in human SMC, respectively.

IC₅₀ & Target

Ki: 4.7 nM (ET_A receptor, in human SMC), 95 nM (ET_A receptor, in human SMC)^[1]

In Vitro

Bosentan (BOS) competitively and specifically antagonizes binding of ¹²⁵I-labelled ET-1 to ET_A receptors on human smooth muscle cells (SMC) and ET_B receptors on human placenta cells. The in vitro binding affinity of Bosentan to ET_A receptors on human SMC is 4.7 nM and to ET_B receptors on human SMC or placenta cells is 41 or 95 nM. Bosentan has 67-fold greater selectivity for ET_A than ET_B receptors (mean IC₅₀=7.1 vs 474.8 nM) in an in vitro ¹²⁵I-labeling assay^[1].

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

In Vivo

In hypertensive rats, Macitentan 30 mg/kg further decreases mean arterial blood pressure (MAP) by 19 mm Hg when given on top of Bosentan hydrate 100 mg/kg. Conversely, Bosentan hydrate given on top of Macitentan fails to induce an additional MAP decrease. In pulmonary hypertensive rats, Macitentan 30 mg/kg further decreases mean pulmonary artery pressure (MPAP) by 4 mm Hg on top of Bosentan hydrate, whereas a maximal effective dose of Bosentan hydrate given on top of Macitentan does not cause any additional MPAP decrease^[3].

Stock Solution Working Solution

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.
