Abstract
Abstract Method of treating virus disorders by administering 1,2-diphenyl-α,β-diketone into the blood. Entry of this compound into the sick cells results in, because of the pH and redox-potential conditions in those cells, oxidation phenomena and deposition of an antiseptic substance in the sick cells, thereby causing cellular aging and necrosis.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
39 words
A method for selective cell necrosis, which comprises administering through the circulatory system to the altered cells of a patient having such altered cells a pharmaceutically effective amount of a composition containing 1,2-diphenyl-α,β-diketone and a pharmaceutically suitable carrier therefor.
Claim 2
Independent Claim
39 words
A method for selective cell necrosis, which comprises administering through the circulatory system to the altered cells of a patient having such altered cells a pharmaceutically effective amount of a composition containing 1,2-diphenyl-α,β-diketone and a pharmaceutically suitable carrier therefor.
Claim 3
Dependent Claim
64 words
The method according to claim 1, wherein the administration is perorally and the composition is prepared by mixing an oil or ethyl oleate, with a low degree of acidity, and 1,2-diphenyl-α ,β-diketone under stirring at a temperature between ambient temperature and 80° C., to dissolve the mixture, the proportion of 1,2-diphenyl-α,β-diketone being between 1 and 4% w/v, and allowing the resultant mixture to cool.
Claim 4
Independent Claim
41 words
A method for selective cell necrosis, which comprises administering into the blood of a patient affected with altered cells, a pharmaceutically effective amount of 1,2-diphenyl-α,β-diketone in the form of a solution in a pharmaceutically acceptable liposoluble medium suitable for internal administration.
Claim 5
Independent Claim
41 words
A method for selective cell necrosis, which comprises administering into the blood of a patient affected with altered cells, a pharmaceutically effective amount of 1,2-diphenyl-α,β-diketone in the form of a solution in a pharmaceutically acceptable liposoluble medium suitable for internal administration.
Claim 6
Dependent Claim
21 words
A composition for achieving selective cell necrosis, comprising 1,2-diphenyl-α,β-diketone and a pharmaceutically acceptable liposoluble medium, as carrier, suitable for internal administration.
Claim 7
Dependent Claim
21 words
A composition for achieving selective cell necrosis, comprising 1,2-diphenyl-α,β-diketone and a pharmaceutically acceptable liposoluble medium, as carrier, suitable for internal administration.
