Hormones

Phenylephrine-2,4,6-d₃ (hydrochloride) is the deuterium labeled Phenylephrine hydrochloride. (R)-(-)-Phenylephrine hydrochloride is a selective α1-adrenoceptor agonist with pKis of 5.86, 4.87 and 4.70 for α1D, α1B and α1A receptors respectively.

(rac)-Metanephrine-d₃ (hydrochloride) is the deuterium labeled (rac)-Metanephrine hydrochloride.

Medroxyprogesterone-d₃ is the deuterium labeled Medroxyprogesterone. Medroxyprogesterone is a progestin, a synthetic variant of the human hormone progesterone and a potent progesterone receptor agonist.

13,14-Dihydro-15-keto-PGE2-d₉ is the deuterium labeled 13,14-Dihydro-15-keto-PGE2.

Bimatoprost acid-d₄ (17-Phenyl trinor PGF2α-d₄) is the deuterium labeled Bimatoprost acid.

Ciclesonide-d₇ is the deuterium labeled Ciclesonide. Ciclesonide (RPR251526) is a glucocorticoid with an potent anti-inflammatory activity. Ciclesonide can be used for asthma research.

Estrone-¹³C₃ is the ¹³C-labeled Estrone. Estrone (E1) is a natural estrogenic hormone. Estrone is the main representative of the endogenous estrogens and is produced by several tissues, especially adipose tissue. Estrone is the result of the process of aromatization of androstenedione that occurs in fat cells.

Prostaglandin D2-d₉ is the deuterium labeled Prostaglandin D2. Prostaglandin D2 (PGD2) is one of the major PGs actively produced in the brain of various mammals. Prostaglandin D2 is one of the most potent endogenous sleep promoting substances. PGD2 plays a protective role by suppressing inflammation.

Estetrol-d₄ is the deuterium labeled Estetrol. Estetrol, a natural estrogen synthesized exclusively during pregnancy by the human fetal liver, is a selective nuclear estrogen receptor modulator. Estetrol exerts estrogenic actions on the endometrium or the central nervous system but presents antagonistic effects on the breast.

11-Dehydro-thromboxane B2-d₄ is the d₄-labeled 11-Dehydro-thromboxane B2 (HY-113420). 11-Dehydro-thromboxane B2 is a stable terminal metabolite of thromboxane A2 and an agonist of the CRTH2 receptor. 11-Dehydro-TXB2 activates human eosinophils, basophils, and CRTH2-transfected BaF/3 cells through a pertussis toxin-insensitive G protein-PLC pathway, inducing intracellular calcium mobilization, morphological changes, and chemotaxis, but does not affect platelet aggregation. 11-Dehydro-thromboxane B2 is involved in thrombosis and promotes eosinophil recruitment to the lungs in allergic inflammation, and its urinary levels are used to assess the inhibitory effect of Aspirin (HY-14654) on thromboxane production. 11-Dehydro-TXB2 serves as a biomarker for research related to asthma, atopic rhinitis, nephropathy, and coronary artery disease.

Drospirenone-d₄ is the deuterium labeled Drospirenone. Drospirenone (Dihydrospirorenone) is a synthetic progestin that is an analog to spironolactone.

Fludrocortisone-d₅ (9α-Fludrocortisone-d₅) is the deuterium labeled Fludrocortisone (HY-B1203). Fludrocortisone is an orally active mineralocorticoid and glucocorticoid receptor agonist. Fludrocortisone suppresses pro-inflammatory cytokine expression, reduces CCL2, IL-6, IL-8 levels, upregulates mineralocorticoid receptor (MR) expression, induces PI3K/Akt, GSK-3β, CREB, ERK1/2, mTOR phosphorylation, blocks Tau hyperphosphorylation, prevents apoptosis, promotes survival and proliferation, enhances renal sodium and water transport, increases plasma volume and blood pressure, reduces plasma potassium and renin activity, stimulates erythropoietin expression, modulates uterine receptivity genes, and reverses PP242-induced MUC1 upregulation. Fludrocortisone can be used for the research of congenital adrenal hyperplasia, postural hypotension, and adrenal insufficiency.

Estriol-¹³C₃ is the ¹³C-labeled Estriol. Estriol is an antagonist of the G-protein coupled estrogen receptor in estrogen receptor-negative breast cancer cells.

Equilin-d₄ is the deuterium labeled Equilin. Equilin (7-Dehydroestrone) is an important member of the large group of oestrogenic substances and is chemically related to menformon (oestrone). Equilin increases the growth of cortical neurons via an NMDA receptor-dependent mechanism.

(Rac)-Hexestrol-d₄ is the deuterium labeled (Rac)-Hexestrol.

(Rac)-Hexestrol-d₆ is the deuterium labeled (Rac)-Hexestrol.

Estradiol valerate-d₉ (β-Estradiol 17-valerate-d₉) is the deuterated-labeled Estradiol valerate (HY-B0672). Estradiol valerate (β-Estradiol 17-valerate) is a synthetic estrogen widely used in combination with other steroid hormones in hormone replacement therapy agents.

1,3,7-Trimethyluric acid-d₉ is the deuterium labeled 1,3,7-Trimethyluric acid.

Alpha-Estradiol-d₃ is the deuterium labeled Alpha-Estradiol. Alpha-Estradiol is a weak estrogen and a 5α-reductase inhibitor which is used as a topical medication in the treatment of androgenic alopecia.

Megestrol acetate-d₃ is the deuterium labeled Megestrol acetate. Megestrol acetate is a synthetic and orally active progesteronal agent. Megestrol acetate is effective as an appetite stimulant for wasting syndromes such as cachexia. Megestrol acetate decreases nuclear and cytosol androgen receptors human BPH tissue. Megestrol acetate has the potential for HIV study and downregulates autophagic catabolic pathway.
