3 Results for "rat right atrium" in MCE Product Catalog:
Cat. No.: HY-135439
CAS No.: 135938-17-9
Target:
Research Areas:
SB-203186 is a highly selective 5-HT4 receptor antagonist. SB-203186 exhibits a potent competitive antagonistic effect, with its pKB value being 8.3 in the isolated right atrium model of piglets. SB-203186 can dose-dependently shift the 5-HT-induced tachycardia curve to the right, and does not inhibit the maximum response. SB-203186 is an efficient 5-HT₄ antagonist in pig and human atria, but has no significant inhibitory effect in rat atria. SB-203186 can be used for the study of diseases such as arrhythmias and abnormal myocardial contraction .
Cat. No.: HY-183859
CAS No.: 88017-05-4
Target:
Research Areas:
H142/08 is a β1-adrenergic receptor-selective agonist. H142/08 induces concentration-dependent relaxation of isolated rat uterus and acts as a chronotropic stimulant to increase atrial rate, and its effects are effectively antagonized by Pafenolol (HY-165495). H142/08 also antagonizes the chronotropic effect of isoproterenol on isolated rat right atrium, but requires a higher proportion of receptor occupancy to produce sufficient stimulatory effects .

The Nobel Prize winning "Click Chemistry" can be used like this!A suitable model is crucial in drug screening experiments. Organs can mimic the three-dimensional functional structure of internal organs, have similar spatial organization to corresponding organs, maintain some key characteristics, and reproduce some physiological functions. They are widely used for modeling and personalized drug screening physiological functions.2025-02-06
