prostaglandin

Phenylbutazone (Butazolidine) is a butyl-diphenyl-pyrazolidinedione that has anti-inflammatory, antipyretic, and analgesic activities. It has been used in ankylosing spondylitis, rheumatoid arthritis, and reactive arthritis.

Prostaglandin E2 (PGE2) is a naturally occurring hormone involved in various physiological processes, such as smooth muscle contraction and relaxation, vasodilation and constriction, blood pressure regulation, and inflammatory regulation.

Prostaglandin G H synthase 1 inhibitor (CP 74006) is a selective D5D inhibitor with an IC(50) value of 20 nM.

Prostaglandin E1 (Alprostadil) is the naturally occurring prostaglandin E1 (PGE1) which displays a variety of pharmacologic actions. Prostaglandin E1 is a potent vasodilator agent that increases peripheral blood flow, inhibits platelet aggregation, and induces bronchodilation. Used in the treatment of erectile dysfunction, this agent produces corporal smooth muscle relaxation by binding to PGE receptors, resulting in the activation of adenylate cyclase and the subsequent accumulation of 3'5'-cAMP.

Prostaglandin F1α (PGF1α) is the putative metabolite of dihomo-γ-linolenic acid (DGLA) via the cyclooxygenase (COX) pathway. Both PGF1α and PGF2α have been shown to act as priming pheromones for male Atlantic salmon with a threshold concentration of 10-11 M. [1] PGF1α binds to the ovine corpus luteum FP receptor at only 8% of the relative potency of PGF2α. [2] It is only half as active as PGF2α in inducing human respiratory smooth muscle contractions in vitro. [3]

13,14-dihydro-15-keto Prostaglandin E1 inhibits ADP-induced platelet aggregation in human isolated platelet-rich plasma (IC50=14.8 μg mL) and is a PGE1 metabolite.

15-keto Prostaglandin F2α is a metabolite of Prostaglandin F2α that lowers intraocular pressure in rabbits.

17-phenyl trinor prostaglandin F2α (17-phenyl trinor PGF2α) derivatives have been approved for the treatment of glaucoma, with unsubstituted or meta-substituted aromatic derivatives being the most potent FP receptor agonists. 17-trifluoromethylphenyl trinor PGF2α, which contains an aromatic ring reminiscent of the trifluoromethyl-phenoxy ring in travoprost ((+)-fluprostenol isopropyl ester), is expected to act similarly to the free acid form of travoprost as an ocular hypotensive agent. Additionally, 17-phenyl trinor PGF2α is a potent luteolytic and abortifacient with a potency equal to or greater than that of fluprostenol and cloprostenol.

9-deoxy-9-methylene Prostaglandin E2 (9-deoxy-9-methylene PGE2) is a stable, isosteric analog of PGE2 that retains its biological profile with fewer side effects. In rats, it is equipotent to PGE2 in decreasing blood pressure and stimulates the gerbil colon and primate uterus with the same potency as PGE2.

11-deoxy PGF1α is a synthetic analog of PGF1α. In whole animal studies, a dose of 32 mg/kg inhibited gastric acid secretion by 35%. 11-deoxy PGF1α is also known to cause rat uterine contractions at a dose 0.3 times that of PGF1α. It also exhibits vasopressor and bronchoconstrictor activities at about half the potency of PGF2α in guinea pigs.

8-iso-13,14-dihydro-15-keto Prostaglandin F2α (8-iso-13,14-dihydro-15-keto PGF2α) is a metabolite of the isoprostane, 8-isoprostane (8-iso PGF2α), in rabbits, monkeys and humans. 8-iso PGF2α is a PG-like product of non-specific lipid peroxidation. In both humans and monkeys, exogenously infused 8-isoprostane is converted primarily to metabolites having 2 or 4 carbon atoms removed from the top side chain by β-oxidation. A similar pattern is observed when tritiated 8-isoprostane is infused into rabbits. Early in the infusion (within 10 minutes) 8-iso-13,14-dihydro-15-keto PGF2α was a significant component of the metabolite profile, which was comprised mostly of dinor 8-isoprostane metabolites. 8-iso-13,14-dihydro-15-keto PGF2α weakly inhibits the U-46619 or collagen-induced aggregation of human platelets, although a number of the E-series isoprostanes are much more potent in this assay.

9-deoxy-9-methylene-16,16-dimethyl Prostaglandin E2 (Meteneprost) is a potent analog of prostaglandin E2 with an extended half-life in vivo. In combination with various other prostaglandin derivatives, it results in the termination of first trimester pregnancy in monkeys. A single intramuscular injection containing 0.5 mg of meteneprost and 7.5 mg of 17-phenyl trinor PGF1α is very effective in terminating early pregnancy. This prostaglandin mixture is ineffective on monkeys in their third trimester of pregnancy. Meteneprost, when compared to PGE2 and PGF1α, in monkey and rat, does not result in unwanted side effects such as fever or gastrointestinal problems.

Bimatoprost is the Allergan trade name for 17-phenyl trinor prostaglandin F2α ethyl amide (17-phenyl trinor PGF2α ethyl amide), an F-series PG analog which has been approved for use as an ocular hypotensive drug. Oxidation of the C-15 hydroxyl group produces 15-keto-17-phenyl trinor PGF2α ethyl amide. 15-keto-17-phenyl trinor PGF2α ethyl amide is a potential metabolite of 17-phenyl trinor PGF2α ethyl amide when 17-phenyl trinor PGF2α ethyl amide is administered to intact animals. No pharmacological studies on 15-keto-17-phenyl trinor PGF2α ethyl amide have been reported.

PGI3 is synthesized from EPA by COX and PGI synthase. PGI3 has a short in vivo half-life and is hydrolyzed to δ17-6-keto PGF1α. The platelet and vascular activity of PGI3 is equivalent to that of PGI2.

16,16-Dimethyl prostaglandin E2 is an orally active vertebrate Hematopoietic stem cells homeostasis critical regulator. It can act through EP2 EP4 and has an interaction with the Wnt pathway.

17-phenyl trinor Prostaglandin F2α cyclopropyl amide (17-phenyl trinor PGF2α cyclopropyl amide) is a novel analog of 17-phenyl trinor PGF2α ethyl amide. There are no published reports on the biological activity of 17-phenyl trinor PGF2α cyclopropyl amide.

16-phenyl tetranor Prostaglandin E2 is an active molecule that can be used in life science related research. The CAS number of 16-phenyl tetranor Prostaglandin E2 is 38315-44-5.

Prostaglandin E1 ethanolamide, an analog of Prostaglandin E1 (PGE1), can potentially inhibit the GLI2-induced expression of target genes such as Gli1 and Ptch1, thereby reducing tumor growth [1].

11-Deoxy-16,16-dimethyl Prostaglandin E2 (11-deoxy-16,16-dimethyl PGE2) is a stable synthetic analog of Prostaglandin E2 (PGE2), acting as an agonist for both EP2 and EP3 receptors. It effectively inhibits gastric acid secretion and ulcer formation in rats, with ED50 values of 1 mg/kg and 0.021 mg/kg, respectively. This compound is also 900 times more potent than Prostaglandin F2α (PGF2α) in inducing contraction of human respiratory tract smooth muscle in vitro.

8-iso-15(R)-Prostaglandin F2α (8-iso-15(R) PGF2α) is a chemically distinct member within a broad group of prostaglandin-like eicosanoids, produced through the free radical peroxidation of arachidonic acid contained in membrane phospholipids. It represents the C-15 epimer of 8-isoPGF2α, distinguished as the sole isoprostane isomer extensively examined across numerous biological systems.

Prostaglandin D2 (PGD2) is a primary enzymatic prostaglandin derived from PGH2 and is abundantly produced in the cerebrospinal fluid (CSF) by the lipocalin-type PGD synthase, and peripherally by myeloid cells such as mast cells and basophils via a hematopoietic-type PGD synthase. PGD2 is chemically unstable and presents challenges for use and analysis due to its brief in vivo half-life. Δ12-PGD2, an initial decomposition product of PGD2, acts as an intermediate in the pathway to Δ12-PGJ2, a cyclopentenone prostaglandin known for its antimitotic and carcinogenic properties. The metabolism of Δ12-PGD2 involves the addition of thiol nucleophiles, a common pathway for many cyclopentenone prostaglandins.

16,16-dimethyl Prostaglandin A1 is a useful organic compound for research related to life sciences. The catalog number is T36040 and the CAS number is 41692-24-4.

Prostaglandin H2 (PGH2), initially isolated from the incubation of arachidonic acid with ovine seminal vesicle microsomes, acts as a potent vasoconstrictor. It serves as the precursor for all 2-series prostaglandins (PGs) and thromboxanes (TXs). Moreover, as a TP receptor agonist, PGH2 irreversibly aggregates human platelets at concentrations of 50-100 ng/ml.

11-deoxy Prostaglandin E1 is a prostaglandin E1 analogue that has bronchodilator activity and can inhibit histamine-induced bronchoconstriction and cause relaxation of tracheal strips in isolated guinea pigs.
