The 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 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 hetroatom 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).sup.m H wherein m is 1-4, OR.sup.1, OOCR.sub.1, NR.sup.1, NCOR.sup.1 and SR.sup.1 ; Y is H, OR.sup.1, OOCR.sup.1, NR.sup.1.sub.2, NCOR.sub.1 or SR.sub.1 ; and X is --CHR.sup.5 (CHOR.sup.1).sub.2 CHR.sup.6 OR.sup.1 wherein R.sup.5 and R.sup.6 are independently H, lower alkyl (1-4C) optionally substituted with one or more R, 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, CHOR.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. These compounds are useful in the treatment of conditions characterized by excess inflammation.
这些化合物的化学式为##STR1## 其中每个R.sup.1独立地为H或较低的烷基(1-4C);R.sup.2为H,较低的烷基(1-4C),烷基芳基或一个或多个额外的糖残基;R.sup.3和R.sup.4独立地为H,烷基(1-6C),芳基或R.sup.3和R.sup.4在一起形成一个五元或六元环,可选地包含从O、S和NR.sup.1组成的杂原子;其中所述的五元或六元环可以进一步被来自羟甲氧基(CHOR.sup.1).sup.m H的一个或多个取代基取代,其中m为1-4,OR.sup.1,OOCR.sub.1,NR.sup.1,NCOR.sup.1和SR.sup.1;Y为H,OR.sup.1,OOCR.sup.1,NR.sup.1.sub.2,NCOR.sub.1或SR.sub.1;X为--CHR.sup.5(CHOR.sup.1).sub.2 CHR.sup.6 OR.sup.1,其中R.sup.5和R.sup.6独立地为H,较低的烷基(1-4C),可选地用一个或多个R取代,或形成一个五元或六元环,可选地包含从O、S和NR.sup.1组成的杂原子;所述的五元或六元环可用来自R.sup.1、CHOR.sup.1、OR.sup.1、OOCR.sup.1、NR.sup.1.sub.2、NHCOR.sup.1、SR.sup.1和F的一个取代基进行取代;或者X为有1-3个羟基取代的苯甲酰基或萘甲酰基,但前提是如果X代表一个己糖取代基,则R.sup.3和R.sup.4在一起不能提供一个己糖取代基。这些化合物在治疗过度炎症的情况下是有用的。
