    • Simple lactose or lactosamine related compounds which behave as ligands for the ELAM-1 and related receptors are described. These compounds are useful in the treatment of conditions characterized by excess inflammation. These compounds are of the formula ##STR1## wherein each R.sup.1 is independently H or lower alkyl (1-4C); R.sup.2 is H, lower alkyl (1-4C), alkylaryl or one or more additional saccharide residues;R.sup.3 and R.sup.4 are each independently H, alkyl(1-6C), aryl or R.sup.3 and R.sup.4, taken together, form a five- or six-membered ring optionally containing a heteroatom selected from the group consisting of O, S, and NR.sup.1 ;wherein said five- or six-membered ring may further be substituted by one or more substituents selected from the group consisting of (CHOR.sup.1).sub.m H wherein m is 1-4, OR.sup.1, OOCR.sup.1, NR.sup.1.sub.2, NHCOR.sup.1, and SR.sup.1 ;Y is H, OR.sup.1, OOCR.sup.1, NR.sup.1.sub.2, NCOR.sup.1 or SR.sup.1 ; andX is --CHR.sup.5 (CHOR.sup.1).sub.2 CHR.sup.6 OR.sup.1 wherein R.sup.5 and R.sup.6 are each independently H, lower alkyl(1-4C) optionally substituted with one or more F, or result in a five- or six-membered ring optionally containing a heteroatom selected from the group consisting of O, S, and NR.sup.1 ;said five- or six-membered ring optionally substituted with one substituent selected from the group consisting of R.sup.1, CH.sub.2 OR.sup.1, OR.sup.1, OOCR.sup.1, NR.sup.1.sub.2, NHCOR.sup.1, SR.sup.1 and F;or X is benzoyl or naphthoyl having 1-3 hydroxyl substituents,with the proviso that if X represents a hexose substituent R.sup.3 and R.sup.4, taken together, cannot provide a hexose substituent.
    • 描述了作为ELAM-1和相关受体的配体的简单的乳糖或乳糖胺相关化合物。 这些化合物可用于治疗以过量炎症为特征的病症。 这些化合物具有式“IMAGE”,其中每个R 1独立地是H或低级烷基(1-4C); R2是H,低级烷基(1-4C),烷基芳基或一个或多个另外的糖残基; R 3和R 4各自独立地为H,烷基(1-6C),芳基或R 3和R 4一起形成任选含有选自O,S和NR 1的杂原子的五元或六元环; 其中所述五元或六元环可以进一步被一个或多个选自(CHOR1)mH的取代基取代,其中m是1-4,OR1,OOCR1,NR12,NHCOR1和SR1; Y是H,OR1,OOCR1,NR12,NCOR1或SR1; 并且X是-CHR 5(CHOR 1)2 CHR 6OR 1,其中R 5和R 6各自独立地为H,任选地被一个或多个F取代的低级烷基(1-4C),或者产生任选含有选自以下的杂原子的五元或六元环 由O,S和NR1组成的组; 所述五元或六元环任选被一个选自由R 1,CH 2 OR 1,OR 1,OOCR 1,NR 12,NHCOR 1,SR 1和F的取代基取代; 或X是具有1-3个羟基取代基的苯甲酰基或萘甲酰基,条件是如果X表示己糖取代基R 3和R 4一起不能提供己糖取代基。
