Title:	Use of ribofuranose derivatives against inflammatory bowel diseases
Abstract:	A method for the prophylaxis or treatment of an inflammatory bowel disease is provided, comprising administering to a patient having or at risk of developing an inflammatory bowel disease a therapeutically or preventatively effective amount of one or more ribofuranose derivatives having the Formula (I): ##STR1## wherein R is a group selected from a carboxamide, an amidine, and pharmaceutically acceptable acid addition salts thereof, and the configuration at the C.sub.2 carbon of the ribofuranose moiety is D or L. The one or more ribofuranose derivatives (I) may be used in combination with further active agents such as antivirals or agents effective against inflammatory bowel disease.

Patent Claims:	1. A method of treatment [or prophylaxis] of an inflammatory bowel disease in a subject in need of said treatment [or prophylaxis], said method comprising: providing one or more ribofuranose derivatives having the Formula (I): ##STR4## wherein R is a group selected from the group consisting of a carboxamide, an amidine and pharmaceutically acceptable acid addition salts thereof and the configuration at the C.sub.2 carbon of the ribofuranose moiety is [D or] L; and administering said one or more ribofuranose derivatives to said subject in an amount effective to treat [or revent] said inflammatory bowel disease. 2. The method of claim 1, wherein the ribofuranose derivative having the Formula (I) comprises at least one derivative selected from the group consisting of [1-.beta.-D-ribofuranosyl-1H-1,2,4-triazole-3-carboxamide,] 1-.beta.-L-ribofuranosyl-1H-1,2,4-triazole-3-carboxamide, [1-.beta.-ribofuranosyl-1H-1,2,4-triazole-3-amidine,] 1-.beta.-L-ribofuranosyl-1H-1,2,4-triazole-3-amidine, pharmaceutically acceptable acid addition salts thereof. 3. The method of claim 2, wherein the ribofuranose derivative having Formula (I) is 1-.beta.-L-ribofuranosyl-1H-1,2,4-triazole-3-carboxamide. 4.
