This invention relates to a compound of the formula: ##STR1## or a pharmaceutically acceptable salt thereof wherein X is oxygen, sulfur, or --CH.dbd.CH--; wherein Z is OR.sup.1 or --NR.sup.4 R.sup.5 ; wherein R.sup.1 is hydrogen, lower alkyl, or a pharmaceutically acceptable cation; wherein R.sup.2 is H, --CH.sub.3 or --C.sub.2 H.sub.5 ; wherein R.sup.3 is OH, H or .dbd.O; wherein R.sup.4 and R.sup.5 may independently be hydrogen, or lower alkyl having 1-6 carbon atoms, or R.sup.4 and R.sup.5 may act together with N to form a cyclic amide of the formula: ##STR2## wherein n is an integer from 4-5; and m is an integer from 0-4. More particularly, this invention relates to compounds of the above formula which have utility as LTB.sub.4 antagonists.
这项发明涉及以下化合物的一种,其化学式为:##STR1##或其药学上可接受的盐,其中X为氧、硫或--CH.dbd.CH--;其中Z为OR^1或--NR^4R^5;其中R^1为氢、较低的烷基或药学上可接受的阳离子;其中R^2为H、--CH_3或--C_2H_5;其中R^3为OH、H或.dbd.O;其中R^4和R^5可以独立地是氢,或者具有1-6个碳原子的较低烷基,或者R^4和R^5可以与N一起形成上述式的环酰胺,其中n是4-5的整数;m是0-4的整数。更具体地,这项发明涉及具有作为LTB_4拮抗剂的功用的上述化合物的化合物。
