TLQP-21, a VGF-derived peptide endowed of endocrine and extraendocrine properties, is a potent G-protein-coupled receptor complement-3a receptor 1 (C3aR1) agonist (EC₅₀: mouse TLQP-21=10.3 μM; human TLQP-21=68.8 μM). TLQP-21 activates C3aR1 to induce an increase of intracellular Ca²⁺. TLQP-21 is used for the research in regulation of nociception and other relevant physiologic functions.

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

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.

Heparan Sulfate 6-O-Sulfotransferase 3 is a sulfotransferase. Heparan Sulfate 6-O-Sulfotransferase 3 is important in heparan sulfate biosynthesis.

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.

Desloratadine (Standard) is the analytical standard of Desloratadine. This product is intended for research and analytical applications. Desloratadine (Sch34117) is the orally active major metabolite of the nonsedating H1-antihistamine Loratadine. Desloratadine is a selective H1-receptor antagonist that has anti-allergic and anti-inflammatory activities.

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.

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.

Danazol standard inhibits the proliferation of cancer cell MDA-MB-231 and MCF-7 with IC₅₀ of 65 µg/mL and 31 µg/mL. Danazol arrests the cell cycle at G1 phase, induces apoptosis in MDA-MB-231 through PKCα signaling pathway.

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

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.

Human Growth Hormone (1-43) is an N-terminal fragment of human growth hormone with specific and pronounced insulin-like activity. Human Growth Hormone (1-43) can be used to study the function and metabolic pathways of growth hormone, a potential obesity-related factor.

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).

LY310762 free base is a selective 5-HT_1D receptor antagonist with a K_i value of 249 nM for the guinea pig receptor. LY310762 free base blocks presynaptic 5-HT_1D autoreceptors and enhances potassium-stimulated [³H]5-HT outflow from guinea pig cortical slices. LY310762 free base abolishes the inhibitory effect of 5-CT (HY-135555)/L-694,247 (HY-101208) on sympathetic nerve-induced renal vasoconstriction mediated by prejunctional 5-HT_1D receptors. LY310762 free base potentiates the increase in extracellular 5-HT concentration induced by Fluoxetine (HY-B0102). LY310762 free base is used in research related to depression and diabetic nephropathy.

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.

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.

Capromorelin (CP 424391) is a pyrazolinone-piperidine dipeptide. Capromorelin is an orally active and potent growth hormone secretagogue (GHS) (hGHS-R1a K_i=7 nM, rat pituicyte EC₅₀=3 nM).

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