HY-A0195

Carboprost tromethamine	Prostaglandin Receptor	Endocrinology
Carboprost tromethamine is the synthetic 15-methyl analogue of prostaglandin F_2α. Carboprost tromethamine can effectively promote law contraction of the uterus and significantly reduce the amount of bleeding during and after delivery .

HY-B0962A

Piperidolate	mAChR	Cardiovascular Disease
Piperidolate is a cholinergic antagonist. Piperidolate prevents ventricular fibrillation during hypothermic cardiac manipulations to support cardiac procedures post-preoperative defibrillation. Piperidolate causes dose-dependent cardiac depression. Piperidolate can be used for the research of ventricular fibrillation .

HY-B0962

Piperidolate hydrochloride	mAChR	Cardiovascular Disease
Piperidolate hydrochloride is a cholinergic antagonist. Piperidolate hydrochloride prevents ventricular fibrillation during hypothermic cardiac manipulations to support cardiac procedures post-preoperative defibrillation. Piperidolate hydrochloride causes dose-dependent cardiac depression. Piperidolate hydrochloride can be used for the research of ventricular fibrillation .

HY-105652

Ambucetamide	Vasopressin Receptor	Neurological Disease
Ambucetamide is an antispasmodic agent. Ambucetamide alleviates menstrual pain .

L-368,899	Oxytocin Receptor	Endocrinology
L-368,899 is an orally active and selective OT (oxytocin ) receptor antagonist, with IC₅₀s of 8.9 and 26 nM for uterus of rat and human, respectively. L-368,899 can cross the blood-brain barrier (BBB). L-368,899 inhibits oxytocin-stimulated uterine contractions in rats and can be used in study of preterm labor .

HY-P1767

Prepro VIP (81-122), human	PACAP Receptor	Cardiovascular Disease
Prepro VIP (81-122), human is a prepro-vasoactive intestinal polypeptide (VIP) derived peptide, corresponding to residues 81-122. Peptide histidine valine 42 (PHV-42) has been designated to correspond exactly to Prepro VIP (81-122), which reduces both the force and frequency of spontaneous contractions of isolated rat uterus .

HY-129278

Lunarine	Parasite	Infection Cardiovascular Disease Neurological Disease
Lunarine is an alkaloid, which can be isolated from the seeds of kale (Lunaria annua). Lunarine lowers the blood pressure, stimulates small intestinal motility, inhibits spontaneous contractions of uterus and nervous system, and exhibits an acute toxicity with LD₅₀ of 62.3 mg/kg in dogs and rabbits. Lunarine exhibits antiparasitic activity through a competitive inhibition of protozoan oxidoreductase trypanothione reductase (TryR) with K_i of 304 μM .

HY-A0195R

Carboprost tromethamine (Standard)	Reference Standards Prostaglandin Receptor	Endocrinology
Carboprost (tromethamine) (Standard) is the analytical standard of Carboprost (tromethamine). This product is intended for research and analytical applications. Carboprost tromethamine is the synthetic 15-methyl analogue of prostaglandin F_2α. Carboprost tromethamine can effectively promote law contraction of the uterus and significantly reduce the amount of bleeding during and after delivery .

HY-129266

NPC 573	Drug Derivative	Endocrinology
NPC 573 is a Bradykinin (HY-P0206) analog. NPC 573 inhibits contraction of the uterus .

HY-A0252A

Bupranolol hydrochloride	Adrenergic Receptor	Cancer
Bupranolol hydrochloride is a non-selective β-adrenergic blocker with potent membrane stabilizing activity. Bupranolol hydrochloride is able to significantly modulate the contractile activity of the non-pregnant human uterus. Bupranolol hydrochloride showed significant effects on spontaneous uterine contractions in an in vitro study in patients with ovarian cancer. Bupranolol hydrochloride is similar in potency to propranolol, another β-adrenergic blocker. Bupranolol hydrochloride is rapidly and completely absorbed in vivo, and its major metabolite is carboxybupranolol .

HY-B0962AR

Piperidolate (Standard)	Reference Standards mAChR	Neurological Disease
Piperidolate (Standard) is the analytical standard of Piperidolate. This product is intended for research and analytical applications. Piperidolate is a cholinergic antagonist. Piperidolate prevents ventricular fibrillation during hypothermic cardiac manipulations to support cardiac procedures post-preoperative defibrillation. Piperidolate causes dose-dependent cardiac depression. Piperidolate can be used for the research of ventricular fibrillation .

HY-135446

BQ-610	Endothelin Receptor	Cardiovascular Disease Endocrinology
BQ-610 is a selective antagonist of the endothelin A receptor (ETA receptor). BQ-610 specifically blocks the ETA receptor, competitively inhibiting the binding of endothelin-1 (ET-1) (a vasoconstrictive peptide) to the receptor, thereby blocking the effects of ET-1 such as vascular smooth muscle contraction, cell mitosis, and inhibition of hormone secretion. BQ-610 significantly alleviates cerebral vasospasm in rabbits. BQ-610 blocks the bronchial epithelial and pulmonary vascular cell proliferation caused by cigarette smoke in rat models. BQ-610 can delay the natural luteal regression in the cow's uterus. BQ-610 can be used for research on vasospasm, abnormal cell proliferation, and reproductive endocrine disorders .
