Description
The preseht invention relates to a benzofuranone derivatives in particular the compound of formula I, which is 5-ch1oro-6-cyclohexyl-2,3-dihydrobenzo-furan-2-one.
Further, in accordance with the invention, the compound of formula I may be obtained by a process comprising lactonizing a compound of formula II, - 2 4370» The lactonization of the compound of formula II in accordance with the process of the invention is effected in accordance with conventional methods, as described in the Example.
The compound of formula II may be obtained in accordance with known methods.
The compound of formula I exhibits pharmacological activity. In particular, the compound exhibits oedema and inflammation inhibiting activity, as indicated in standard tests, for example in the carrageen oedema test, in the Adjuvans arthritis test and the granuloma cyst test in the rat and in the UV erythma test in the guinea-pig.
In standard tests, the compound of formula I exhibits further effects, such as an anti-pyretic effect, an analgesic effect, or an inhibition of PG synthetase or of collagen-induced blood platelet aggregation.
The compound is therefore indicated for use as an inhibitor of oedemas and inflammations. An indicated daily does is from 60 to 300 mg, conveniently administered in divided doses 2 to 4 times a day in unit dosage form containing from 15 to 150 mg of the compound, or in sustained release form.
The present invention also provides a pharmaceutical composition comprising a compound of formula I, in association with a pharmaceutical carrier or diluent. Such compositions may be in the form of, for example, a solution or a tablet.
The compound may be prepared as in the following Example in which all temperatures are indicated in degrees Celcius.
The compound of formula II is described and claimed in our British Patent Specification No. 1,546,703.
EXAMPLE.
-Chloro-6-cyclohexyl-2,3-dihydrobenzofuran-2-one g of 3'-chloro-4'-cyclohexyl-6'-hydroxyphenylacetic acid are dissolved in toluene with heating, 50 mg of p-tol uenesul phonic acid are added, and the mixture is boiled in a water separator for 3 hours. The oil obtained - 3 4370S after evaporation is purified on a 100-fold quantity of silica gel Merck (Registered Trade Mark). The desired product is eluted with chloroform and recrystallized from methylene.chloride/petroleum ether. The crystals have an M.P. of 100-102°.
Claims (5)
1. A process for the production of a compound of formula I,
2. A process for the production of the compound of formula I, as stated in Claim 1, substantially as hereinbefore described with reference to the Example.
3. The compound of formula I, as stated in Claim 1, whenever produced by a process according to Claim 1 or 2.
4. The compound of Claim 1, as stated in Claim 1.
5. A pharmaceutical composition comprising the compound according to Claim 3 or 4, in association with a pharmaceutically acceptable diluent or carrier.
