Abstract
Abstract A therapeutic preparation having excellent effect for peptic ulcers with low toxicity which comprises aliphatic ketone derivative of the general formula: ##STR1## wherein represents a saturated or unsaturated bond, R 1 is hydrogen or a lower alkyl group, R 2 is hydrogen atom, a lower alkyl group or a lower alkylcarbonyl group, R 3 is an aliphatic hydrocarbon group of the general formula: ##STR2## WHEREIN L, M AND N ARE 0 OR 1, PROVIDED THAT L+M+N≧2; AND A, B, C, D, E AND F ARE HYDROGEN ATOM, OR THEY MAY FORM A BOND OF A--B, C--D OR E--F, PROVIDED THAT IF THE BOND IS A SATURATED BOND, THE A, B, C, D, E AND F REPRESENT ALL HYDROGEN ATOM.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
124 words
A method of treating a peptic ulcer which comprises administering to a patient an effective ulcer treating amount of an aliphatic ketone derivative of the general formula: ##STR9## wherein represents a saturated or unsaturated bond, R 1 is hydrogen or a lower alkyl group, R 2 is a hydrogen atom, a lower alkyl group, or a lower alkylcarbonyl group, R 3 is an aliphatic hydrocarbon group of the formula: ##STR10## wherein l, m and n are 0 or 1, provided that l+m+n√2; and a, b, c, d, e and f are hydrogen atoms, or they may form a bond of a-b, c-d, e-f, provided that if the bond is a saturated bond, the a, b, c, d, e and f all represent hydrogen atoms.
Claim 2
Independent Claim
124 words
A method of treating a peptic ulcer which comprises administering to a patient an effective ulcer treating amount of an aliphatic ketone derivative of the general formula: ##STR9## wherein represents a saturated or unsaturated bond, R 1 is hydrogen or a lower alkyl group, R 2 is a hydrogen atom, a lower alkyl group, or a lower alkylcarbonyl group, R 3 is an aliphatic hydrocarbon group of the formula: ##STR10## wherein l, m and n are 0 or 1, provided that l+m+n√2; and a, b, c, d, e and f are hydrogen atoms, or they may form a bond of a-b, c-d, e-f, provided that if the bond is a saturated bond, the a, b, c, d, e and f all represent hydrogen atoms.
Claim 3
Dependent Claim
