Unoprostone (INN) is a prostaglandin analogue. Its isopropyl esterunoprostone isopropyl, was marketed under the trade name Rescula for the management of open-angle glaucoma and ocular hypertension, but is now discontinued in the US.[1]

Unoprostone isopropyl is a prostaglandin analogue. Ophthalmic Solution 0.15% is a synthetic docosanoid. Unoprostone isopropyl has the chemical name isopropyl (+)-(Z)-7-[(1R,2R,3R,5S)-3,5 dihydroxy-2-(3-oxodecyl)cyclopentyl]-5-heptenoate. The main indication of Unoprostane is treatment of glucoma.

This compound can be prepared by two different ways: 1) The reaction of 1-benzyl-4-(hydroxymethyl)pyrrolidin-2-one (I) with SOCl2 in refluxing dichloromethane gives 1-benzyl-4-(chloromethyl)pyrrolidin-2-one (II), which is condensed with potassium phthalimide (III) in DMF yielding 1-benzyl-4-(phthalimidomethyl)pyrrolidin-2-one (IV). Finally, this compound is treated with hydrazine in ethanol and neutralized with fumaric acid. 2) The dehydration of 1-benzyl-2-oxo-pyrrolidine-4-carboxamide (V) with POCl3 in hot DMF gives 1-benzyl-4-cyanopyrrolidine-2-one (VI), which is reduced with H2 and RaNi in methanol – NH3 and neutralized with fumaric acid. EP 0289349; JP 1989151552; US 5001153; US 5106869

The condensation of dimethyl methylphosphonate (I) with ethyl octanoate (II) by means of butyllithium in THF gives dimethyl 2-oxononylphosphonate (III), which is condensed with the protected aldehyde (IV) by means of NaH in THF, yielding the unsaturated ketone (V). The hydrogenation of (V) with H2 over Pd/C in ethyl acetate affords the corresponding saturated ketone (VI), which is treated with ethylene glycol and p-toluenesulfonic acid to give the cyclic ketal (VII). The mild hydrolysis of (VII) with K2CO3 and acetic acid gives the alcohol derivative (VIII); the reduction of the lactone group of (VIII) with dibutylaluminum hydride in toluene affords the lactol (IX), which is condensed with (4-carboxybutyl)triphenylphosphonium bromide (X) by means of NaH in DMSO yielding the protected prostaglandin (XI). Esterification of (XI) with isopropyl iodide and DBU in acetonitrile gives the precursor (XII), which is finally deprotected with acetic acid in THF – water.

Dipivefrine hydrochloride

CAS 64019-93-8 

Dipivefrine hydrochloride

  • Formula:C19H29NO5 • HCl
  • MW:387.90 g/mol

Dipivefrine (INN) or dipivefrin (USAN), trade name Propine among others, is a prodrug of epinephrine, and is used to treat open-angle glaucoma.[1][2] It is available as a 0.1% ophthalmic solution. It is no longer available in the United States.[3]

Dipivefrin is a prodrug with little or no pharmacologically activity until it is hydrolyzed into epinephrine inside the human eye. The liberated epinephrine, an adrenergic agonist, appears to exert its action by stimulating α -and/or β2-adrenergic receptors, leading to a decrease in aqueous production and an enhancement of outflow facility. The dipivefrin prodrug delivery system is a more efficient way of delivering the therapeutic effects of epinephrine, with fewer side effects than are associated with conventional epinephrine therapy. Dipivefrin is used as initial therapy for the control of intraocular pressure in chronic open-angle glaucoma.

Contraindications

Use in narrow-angle glaucoma may be dangerous because it could make the eye susceptible to an attack of angle closure,[2] causing an increase in pressure and pain, and possibly loss of vision.

Side effects

The most common side effects of dipivefrine are burning, stinging and other irritations of the eye. Possible, but uncommon, side effects are those of epinephrine: tachycardia (fast heartbeat), hypertension (high blood pressure) and arrhythmias (irregular heartbeat).[2]

Pharmacology

Dipivefrine penetrates the cornea and is then hydrolysed to epinephrine by esterase enzymes. It increases outflow of the aqueous humour and also reduces its formation (mediated by its action on α1 and α2 receptors), thus reducing pressure inside the eye. It also increases the conductivity of trabecular filtering cells (a β2 receptor mediated action). It is preferred to epinephrine because it is longer acting, more consistent in its action and better tolerated.[1]
