Research Areas:
MK-8825 is an orally active, selective CGRP receptor antagonist with a Ki value of 47 pM for human CGRP receptors and 17 nM for rat CGRP receptors. MK-8825 blocks CGRP-stimulated cAMP responses and exhibits competitive-like antagonism. MK-8825 can be used in the research of migraine and temporomandibular joint disorders .

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 .
Target:
Research Areas:
Benzcyclane (Bencyclane; Benzcyclan) is a vasodilator with serotonin receptor antagonism. Benzcyclane exerts atypical serotonin antagonistic effects in rabbit superior mesenteric arteries. Benzcyclane relaxes high K +-induced contractions in rabbit basilar arteries and superior mesenteric arteries, and selectively inhibits sympathetic nerve stimulation-induced contractions in rabbit pulmonary arteries. Benzcyclane exerts non-competitive norepinephrine antagonistic effects in rabbit superior mesenteric arteries, and slightly reduces the maximum contractile response induced by histamine. Benzcyclane relaxes smooth muscles, induces transient hypotension, inhibits thrombosis, and accelerates blood fibrinolytic activity. Benzcyclane increases cerebral glucose content/uptake, enhances hypoxia tolerance in mice, and increases cerebral blood supply in dogs. Benzcyclane is applicable to studies related to cerebral vascular circulation .
Cat. No.: HY-19012
CAS No.: 93750-14-2
Target:
Research Areas:
N-1518 is an α and β adrenergic receptor blocker that has competitive antagonism against β1 and α1 receptors, but does not show selectivity for β1 receptors, but shows about 20-fold selectivity for α1 receptors. N-1518 has vasodilatory effects and can be used in the research field of hypertension treatment .
Cat. No.: HY-W424730
CAS No.: 42585-88-6
HA-966 hydrochloride is a glycine site antagonist of the NMDA receptor, exhibiting non-competitive antagonism on NMDA responses. HA-966 hydrochloride effectively blocks the enhancement of NMDA responses by glycine in a competitive manner. HA-966 hydrochloride plays a significant role in mediating the antagonist action at the glycine modulatory site of the NMDA receptor.
Cat. No.: HY-19633A
CAS No.: 216776-73-7
Target:
Research Areas:
CS-003 is a triple neurokinin receptor antagonist with activity in inhibiting neurokinin-related respiratory diseases. CS-003 exhibits high affinity for human neurokinin 1, 2 and 3 receptors, withKi values of 2.3 nM, 0.54 nM and 0.74 nM respectively. The Ki values of CS-003 on the guinea pig neurokinin receptor are 5.2 nM, 0.47 nM and 0.71 nM respectively, showing superior inhibitory effect. CS-003 significantly inhibits the formation of inositol phosphate involving substance P, neurokinin A and neurokinin B through competitive antagonism. CS-003 significantly inhibits citric acid-induced cough, and its effect is better than other selective neurokinin receptor antagonists .
Cat. No.: HY-182427
CAS No.: 78441-46-0
Target:
Research Areas:
ORF 17583 is a Ranitidine (HY-B0693) analogue and H2 receptor antagonist. ORF 17583 exhibits typical reversible competitive antagonism in the guinea pig right atria model, causing a dose-dependent rightward shift of the histamine concentration-response curve without reducing the maximum effect, and its action is fully reversible upon washing. ORF 17583 can be used for research on peptic ulcers and hyperacidity .
Cat. No.: HY-182635
CAS No.: 83812-65-1
Research Areas:
ICI 147798 is an orally effective β-adrenoceptor antagonist with a pKB of 9.1 (in guinea pig right atrium) and 8.8 (in guinea pig trachea). ICI 147798 acts as a diuretic and intraocular pressure-lowering agent. ICI 147798 blocks β-adrenoceptors, inhibits isoproterenol-induced tachycardia and vasodepressor responses, exhibits slowly dissociating, insurmountable antagonism against β1-adrenoceptors, and shows surmountable competitive antagonism against β2-adrenoceptors. ICI 147798 induces natriuresis and kaliuresis, inhibits sodium transport, and reduces intraocular pressure .
Cat. No.: HY-U00134A

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
