らなる議論は、Phillipsらによる文献The Lancet,767〜
768(1984年4月7日)に記載されている。Anti-inflammatory steroids (eg, hydrocortisone, prednisolone, dexamethasone, and fluorometholone) are very useful in controlling a wide range of ocular inflammatory conditions. Because of the steroid-induced side effects associated with chronic use of these compounds, this utility may be somewhat negated. These side effects include increased intraocular pressure (IOP) in patients with steroid hypersensitivity (steroid responders), increased IOP in patients with glaucoma sensitivity, or frank prmary open angle glaucoma May be manifested by worsening IOP in patients who have had it. Further discussion of this side effect can be found in the article by Phillips et al., The Lancet , 767.

が必要である。本発明は、この要求を満足するためのも
のである。The onset of the symptoms generally can be tolerated in most patients at relatively short therapeutic institutions (ie, 4-6 weeks or less). However, the increase in IOP caused by these compounds is generally unacceptable over extended periods of treatment (i.e., 1 to 12 months or more), especially in individuals with chronic eye inflammation. . The increase in intraocular pressure associated with prolonged use of these compounds may also be unacceptable for certain patients, such as those with increased intraocular pressure (eg, glaucoma patients). Therefore, there is a need for an effective means of treating inflamed ocular tissue without the danger of increasing IOP. The present invention satisfies this need.

に効果の分立が達成される。It is possible that the apparently small structural changes in the steroid molecule, possibly by altering the action of the drug on target cells, can significantly enhance or adversely affect the pharmacological properties of the compound being studied.
It has been recognized by studies of structure-activity relationships in steroid chemistry. These changes can confer agonist or antagonist properties on the steroid molecule. Agonist drugs are broadly defined as compounds that elicit or activate a biochemical response in situations where the mechanism that elicits the response is uncertain. On the other hand, antagonist drugs are broadly defined as inhibitors of the above-mentioned selective response. For example, it has been observed that certain side chain modifications inhibit or inhibit systems that synthesize proteins that regulate the undesirable side effect of IOP, thereby impairing IOP regulation. Thus, just a segregation of effects is achieved if a given steroid is designed to have the property of providing an agonistic property in terms of retaining anti-inflammatory properties and an antagonistic property in terms of completely suppressing the increase in IOP.

ンに抗炎症特性が付与されるが眼圧は増加しない化合物
が得られる。このことは、慢性的な使用(例えば、1ケ
月またはそれを超える)においてさえも当てはまる。The present invention is based on the discovery of some novel derivatives of known anti-inflammatory steroids (eg, dexamethasone and fluocinolone), which derivatives are desirably effective and fractionated. For example, substituting the proton of the C21 hydroxyl group of dexamethasone with a methyl group to produce a C21 methyl ether imparts anti-inflammatory properties to dexamethasone, but contrary to what is commonly observed for dexamethasone and other steroids. A compound is obtained in which the pressure does not increase. This is true even for chronic use (eg, one month or more).

よりさらに説明する。The dexamethasone ether derivative of the present invention is a liquid-
It can be synthesized using a liquid or liquid-solid phase transfer catalyst. As the name implies, phase transfer catalysts are used in two-phase systems; one phase is an aqueous phase and the other is an organic phase. Alternatively, a single anhydrous organic phase is a solid base (eg,
KOH and either a quaternary amine or polyamine catalyst (eg, tetramethylene diamine), wherein the catalytic activity is on the surface of the base crystal. The catalyst used in the present invention is an alkylated quaternary amine (eg, tetrabutylammonium sulfate,
C8-C10 methyltrialkylammonium chloride, cetyltriethylammonium bromide, benzyltriphenylphosphonium chloride, hexadecyltrimethylammonium bromide, tetrapentylammonium bromide, and tetrahexylammonium chloride)
It is. The reaction components are listed below: C1-C5 alkyl halides; branched alkyl halides (eg, isopropyl bromide); aryl halides (eg, benzyl bromide): and acetylenic halides (eg, propargyl bromide). The general mechanism of the synthesis using a phase transfer catalyst is shown below. Initially, the steroid anion complexes with the quaternary cation to form a lipophilic complex. This lipophilic complex then migrates to the organic phase and reacts with the alkyl halide to form the dexamethasone ether derivative. The catalyst then regenerates and returns to the aqueous phase to react with the anions. The above synthesis method is further described by the following examples.

Was added. The mixture was stirred and warmed to 35 ° C., at which point 2 g of dexamethasone (5.1 × 10 −3 mol) was slowly added, followed by another 5 ml of toluene. The mixture is stirred for 5 minutes and then 3 ml of 50% sodium hydroxide solution (2.5 ×
10 -3 mol). This mixture is allowed to equilibrate for 1-2 minutes,
Then 1.65 ml of iodomethane (2.62 × 10 −2 mol, 5.1 equivalents) were added dropwise and the temperature was raised to 37 ° C. Within 3-5 minutes after the addition of iodomethane, a yellow ether precipitated from solution. The reaction was continued for another 20 minutes. At this point, the contents of the flask were emptied with 200 m of 5% sodium chloride solution in a separatory funnel.
Pour and shake slightly to separate the layers. The strongly alkaline lower phase was removed and the organic phase was mixed well

The washed organic phase was allowed to stand in a separatory funnel for 1 hour and separated into two phases, a clear tan (Adogen 464 catalyst) upper layer and a turbid yellow lower layer. The lower layer was poured into ice-cooled 250 ml of ethyl ether and a white product precipitated. Cooling at 4 ° C. overnight completed the product precipitation. The residual Adogen catalyst was removed from the filtered product of the precipitate with ether / toluene (200 ml) followed by ethyl ether (200 ml) and dried at 60 ° C.
