Antazoline phosphate is an H1 receptor antagonist that affects the activity of the central nervous system, has a potent antiarrhythmic effect. Antazoline phosphate is a histamine H1 receptor antagonist with anticholinergic and antiviral properties. Antazoline phosphate can prevent histamine from acting on target cells through a reversible competition effect on histamine receptor sites of these cells. Antazoline phosphate can exert an antiallegic effect and prevent the occurrence of physiological reactions from the effect of blocking as well as inhibiting H1 receptor. Antazoline phosphate can effectively reduce HBV DNA in the extracellular supernatant in a dose-dependent manner, with EC₅₀ of 2.910 μmol/L in HepAD38 cells. Antazoline phosphate also has a significant inhibitory effect on HBV DNA in the extracellular supernatant of Huh7 cells (EC₅₀ = 2.349 μmol/L). Antazoline phosphate has anti-arrhythmic effect in acute myocardial infarctions. Antazoline phosphate can be studied in research for cardiovascular diseases, and HBV.

Menotropin (Menotrophin) is a hormone that can be extracted from the urine of postmenopausal women and has both follicle stimulating hormone (FSH) and luteinizing hormone (LH) activity.

Bimatoprost-d₄ is the deuterium labeled Bimatoprost. Bimatoprost is a prostaglandin analog used topically (as eye drops) to control the progression of glaucoma and in the management of ocular hypertension.

Maropitant-¹³C,d₃ is the ¹³C- and deuterium labeled Maropitant. Maropitant is a selective and orally active neurokinin (NK1) receptor antagonist. Maropitant acts by blocking the binding of substance P within the emetic center and the chemoreceptor trigger zone (CRTZ). Maropitant is highly effective in preventing vomiting.

Stephaniae tetrandrae radix extract is an extract of Stephaniae Tetrandrae Radix used in research on rheumatism.

Kentsin (Thr-Pro-Arg-Lys), a contraceptive tetrapeptide, is originally extracted from hamster embryos. Kentsin prevents the maturation of Graafian follicles and consequently inhibits ovulation, without binding to opioid receptors. Kentsin has opiate properties on gastrointestinal motility.

Gastric Inhibitory Polypeptide (1-30), porcine lacks the C-terminal 12 amino acid residues of natural gastric inhibitory polypeptide (GIP), exhibits biologic activity by potentiating the release of insulin and somatostatin.

17-Phenyl trinor prostaglandin F2α glycinamide methyl ester is a derivative of Bimatoprost (HY-B0191) and a prostaglandin analog. 17-Phenyl trinor prostaglandin F2α glycinamide methyl ester is a human prostaglandin FP receptor agonist. 17-Phenyl trinor prostaglandin F2α glycinamide methyl ester has an ocular hypotensive effect and can be used in the study of ocular hypertension and glaucoma.

ML085 is an inhibitor of placental alkaline phosphatase (PLAP). ML085 can be used in the research of testicular tumors, endocrine and metabolic diseases, and genitourinary system diseases.

Locustatachykinin I TFA is a insect tachykinin-related peptide isolated from Locusta migratoria. Locustatachykinin I TFA exhibits sequence homologies with the vertebrate tachykinins. In Lacanobia, Locustatachykinin I TFA is also a substrate for a deamidase.

(±)-Befunolol is a β-adrenoceptor blocking agent.

TGI-15 is a highly selective prostaglandin F receptor antagonist. TGI-15 inhibits downstream signaling pathways by blocking the binding of PGF2 α to FP receptors. TGI-15 can be used for research on fibrotic and inflammatory conditions.

pTH-Related Protein (1-40) (human, mouse, rat) stimulates calcium uptake in rat intestinal cells through PTHR1 receptor and PKCα/β signaling pathways. pTH-Related Protein (1-40) up-regulates parathyroid hormone 1 receptor (PTHR1) protein, four transcellular calcium transporters, potential vanillin member 6 (TRPV6), calcium-binding protein-D9K (CaBP-D9k), sodium-calcium Exchanger 1 (NCX1) and plasma membrane calcium ATPase 1 (PMCA1).

Prostaglandin D2 serinol amide is a weak inhibitor of the hydrolysis of [3H]2-oleoylglycerol.

Dienestrol-d₈ is the deuterated-labeled Dienestrol (HY-B1403). Dienestrol is an orally active nonsteroidal estrogen. Dienestrol prevents the formation of implantation swellings in the uterus by inhibiting ovum discharge.

Thalictoside is found in A. squamosa L. Thalictoside is a sEH inhibitor (IC₅₀: 20.2 µM). Thalictoside exerts anti-osteoporotic effects through an estrogen-like mechanism. Thalictoside can be used in the research of cardiovascular and urinary diseases.

Latanoprost ethyl amide-d₄ (Lat-NEt-d₄) is deuterium labeled Latanoprost ethyl amide. Latanoprost ethyl amide (Lat-NEt) is a latanoprost analog in which the C-1 carboxyl group has been modified to an N-ethyl amide. Prostaglandin esters have been shown to have ocular hypotensive activity.1 Prostaglandin N-ethyl amides were recently introduced as alternative prostaglandin ocular hypotensive prodrugs. Although it has been claimed that prostaglandin ethyl amides are not converted to the free acids in vivo, studies in our laboratories have shown that bovine and human corneal tissue converts the N-ethyl amides of various prostaglandins to the free acids with a conversion rate of about 2.5 μg/g corneal tissue/hr. Lat-NEt would be expected to show the typical intraocular effects of Latanoprost free acid, but with the much slower hydrolysis pharmacokinetics of the prostaglandin N-amides.

YM116 is an orally active and competitive CYP17A1 (17,20-lyase) inhibitor (K_i: 0.38 nM). YM116 reduces the synthesis of adrenal androgens by preferentially inhibiting C17-20 lyase activity. YM116 decreases the serum testosterone concentration, reduces dehydroepiandrosterone sulfate levels and decreases prostatic weights.

PGF2α analogue-1 is an analog of Dinoprost (HY-12956) containing an acetylenic fluorobenzene substituent in the lower side chain.

HMR-3339 is a new selective estrogen receptor modulator. HMR-3339 reduces total cholesterol, low-density lipoprotein cholesterol, and homocysteine. HMR-3339 corrects bone alterations induced by ovariectomy.
