Latanoprost Chemische Eigenschaften,Einsatz,Produktion Methoden

• Beschreibung

  Xalatan was launched in Sweden, Switzerland and the US for the treatment of glaucoma. It can be synthesized, from the Corey lactone, using standard prostaglandin chemistry. Latanoprost is a PGF_2α, analog that is more lipophilic thus is better able to penetrate the cornea. The (15R)-diastereomer has only 10% of the activity compared to the (15S)-diastereomer. It is a selective FP receptor agonist with little or no effect on the other prostanoid receptors. The antiglaucoma effects are the result of reduced intraocular pressure arising by increasing uveoscleral outflow with little or no effect on trabeculo-canalicular aqueous outflow and no effect on retinal vasculation or permeability of the blood-aqueous barrier. The topical application is sufficient for a single daily dosage and is well tolerated with no detectible conjunctival hyperaemia.

• Verwenden

  Latanoprost is the isopropyl ester of 17-phenyl-13,14-dihydro prostaglandin F2α (17-phenyl-13,14-dihydro PGF2α). It is a prodrug form of the free acid, which is a potent agonist of the FP receptor in the eye. Latanoprost reduces intraocular pressure in glaucoma patients with few side effects. The EC50 value of latanoprost (tested as the free acid) for FP receptors is 3.6 nM.

• Verwenden

  Prostaglandin analog, used to treat glaucoma and other degenerative diseases of the eye.

• Definition

  ChEBI: A prostaglandin Falpha that is the isopropyl ester prodrug of latanoprost free acid. Used in the treatment of open-angle glaucoma and ocular hypertension.

• Manufacturing Process

  Manufacturing process for Latanoprost includes these steps as follows: Synthesis of [3aR-[3aα,4α(E),5β,6aα]]-5-(benzoyloxy) hexahydro-4-(3-oxo-5-phenyl-1-pentenyl)-2H-cyclopenta[b]furan-2-one, synthesis of [3aR-[3aα,4a(1E,3S),5β,6aα]]-5-(benzoyloxy)hexahydro- 4-(3 -hydroxy-5-phenyl-1-pentenyl)-2H-cyclopenta[b]furan-2-one, synthesis of [3aR-[3aα,4a(1E,3S),5β,6aα]]- 5-(benzoyloxy)hexahydro-4-(3-hydroxy-5-phenyl-1-pentyl)-2Hcyclopenta[b]furan-2-one, synthesis of 2-[(1R,2R,3R,5S)-3,5-dihydroxy-2-[(3R)-3-hydroxy-5- phenylpentyl]cyclopentyl]acetic acid, synthesis of [3aR-[3aα,4α(R),5β,6aα]]-hexahydro-5-hydroxy-4-(3-hydroxy-5- phenylpentyl)-2H-cyclopenta[b]furan-2-one, synthesis of [3aR-[3aα,4α(R),5β,6aα]]- hexahydro-5-hydroxy-4-(3-hydroxy-5-phenylpentyl)-2H-cyclopenta[b]furan-2-one;synthesis of (3aR,4R,5R,6aS)-5- (1-ethoxyethoxy)-4-[(3R)-3-(1-ethoxyethoxy)-5-phenylpentyl]hexahydro-2Hcyclopenta[b]furan-2-ol;synthesis of 7-[(1R,2R,3R,5S)-3-(1-ethoxyethoxy)-5- hydroxy-2-[(3R)-3-(1-ethoxyethoxy)-5- phenylpentyl]cyclopentyl-5-heptenoic acid; synthesis of (5Z)-7-[(1R,2R,3R,5S)-3,5-dihydroxy-2-[(3R)-3-hydroxy-5- phenylpentyl]cyclopentyl]-5-heptenoic acid (Latanoprost Acid); At last, Latanoprost acid is dissolved in DMF (10 mL) and added to a slurry of cesium carbonate (1.6 g) in DMF (10 mL). 2-Iodopropane (0.49 mL) is added and the slurry is heated to 45°C for about 6 hours. When the reaction is complete, MTBE (40 mL) and water (50 mL) are added and the mixture is stirred for 15 min. The phases are separated and the aqueous phase is washed with MTBE (20 mL). The organic phases are combined and concentrated. The concentrate is chromatographed (silica gel) eluting with MTBE. The appropriate fractions are pooled and concentrated to give (5Z)-(9CI)-7-[(1R,2R,3R,5S)-3,5- Dihydroxy-2-[(3R)-3-hydroxy-5-phenylpentyl ]cyclopentyl]-5-heptenoic acid 1- methylethyl ester (Latanoprost).

• Therapeutic Function

  Antiglaucoma

• Allgemeine Beschreibung

  Latanoprost (Xalatan) is available as a 0.005% sterileophthalmic solution in a 2.5-mL dispenser bottle.Latanoprost is also marketed as a combination ophthalmicproduct with the β-adrenergic blocking agent, timolol,which apparently enhances IOP-lowering by decreasing theproduction of aqueous humor. Cautions and side effects aresimilar to those for other ophthalmic prostanoids.

• Biochem/physiol Actions

  Latanoprost is a potent, selective prostaglandin F2α?analog receptor agonist. It is hydrolyzed by esterases into its biologically active form latanoprost acid in the cornea. Latanoprostplays a role in reducing the intraocular pressure (IOP) due to which it has therapeutic effects in treating glaucoma.

• Sicherheitsprofil

  A poison by ingestion and intravenous route. Human systemic effects. When heated to decomposition it emits acrid smoke and irritating vapors.
