Compounds of the general formula ##STR1## wherein R represents a group selected from: ##STR2## AND ##STR3## where: N = 0,1; X = OH, OCH.sub.3, OC.sub.2 H.sub.5 ; y = h, ch.sub.3 ; r.sub.1, r.sub.2, that may be the same or different = H, CH.sub.3, C.sub.2 .sub.5, C.sub.3 H.sub.7 ; and their water soluble pharmaceutically acceptable salts. The compounds are prepared by introducing the acidic moiety upon the heterocyclic nuclei which can be prepared according to known procedure. The present invention relates to novel antiinflammatory agents and specifically to certain novel heterocyclo alkanoic acids. More particularly it relates to heterocyclo-acetic and to 2-(heterocyclo)propionic acids in which the heterocyclo moiety of the molecule is an oxygen containing nucleus.
通式为##STR1##其中R代表以下选定的基团之一:##STR2##和##STR3##其中:N = 0,1; X = OH,OCH.sub.3,OC.sub.2 H.sub.5;y = h,ch.sub.3;r.sub.1、r.sub.2,可能相同也可能不同= H,CH.sub.3,C.sub.2 .sub.5,C.sub.3 H.sub.7;以及其水溶性药用可接受盐。该化合物是通过在杂环核上引入酸性基团制备的,可以根据已知的程序制备。本发明涉及新型抗炎药物,特别是某些新型杂环烷基酸。更具体地,它涉及杂环乙酸和2-(杂环基)丙酸,其中分子的杂环部分是含氧核。
