H87/07

H87/07 is a cardioselective β1-adrenoceptor antagonist with intrinsic sympathomimetic activity. H87/07 has a pK_i of 7.00 for the human β1-adrenoceptor. In isolated cat and guinea pig atrial/papillary muscle models, H87/07 exerts β-blocking effects at low concentrations and exhibits cardiac stimulatory effects only at higher concentrations. H87/07 can be used for research on angina pectoris.

For research use only. We do not sell to patients.

Cardiovascular Regulation

H87/07 (compound 7) binds to the human β₁-adrenoceptor expressed in CHO cell membranes with a pKi of 7.00; it antagonizes the β1-AR chronotropic response mediated by (-)-isoproterenol in isolated rat atria with a pA₂ of 7.37^[1].

Cardiovascular Regulation

Regulation of Cardiac Pump Function

H87/07 (compound 3) acts as a partial chronotropic agonist in isolated cat and guinea pig right atria, with higher intrinsic activity in kitten atria; it blocks the chronotropic response to isoproterenol, with mean -log K_B values of 6.9 and 6.7 in kitten and guinea pig right atria, respectively^[2].
H87/07 (2 × 10^-6 M) yields -log K_B values of 6.62 and 6.45/6.47 in kitten right atrium and left atrium, indicating similar apparent affinities for chronotropic and inotropic responses^[2].
H87/07 has a -log K_S of 7.0 in both kitten and guinea pig atria, a -log EC₅₀ of 7.3 in kitten atria, and 6.9 in guinea pig atria^[2].

In Vivo

Cardiovascular RegulationRegulation of Cardiac Pump Function

Cardiovascular Regulation

Compared with Metoprolol (HY-17503), H87/07 produces a smaller reduction in resting heart rate and a longer recovery time of ST-segment depression after exercise^[3].

Cardiovascular Regulation

Regulation of Cardiac Pump Function

H87/07 is a cardioselective β-blocker with intrinsic sympathomimetic activity, and its potency in blocking isoproterenol-induced tachycardia in vivo is 0.4 times that of propranolol^[3].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
