Abstract

The invention relates to tricyclic compounds of the formula I where X1 is carboxyl or 5-tetrazolyl; X2 is carbonyl or methylene; X3 is hydroxyl or a group -X4 (CnH2n)X5, where X4 is oxygen or sulphur and X5 is hydrogen or a group -OX6, where X6 is hydrogen, an alkanoyl having 1-4 carbon atoms or a group -(CmH2m)X7, where X7 is hydrogen or a group -OX8, where X8 is hydrogen or acetyl and m and n are both independently an integer from 1 to 4, with the proviso that, when X5 is a group -OX6, n is then always greater than 1 and X4 and X5 are linked to different carbon atoms and that, when X7 is a group -OX8, m is then always greater than 1 and no carbon atoms in the chain -(CmH2m)- is linked to two oxygen atoms, and to the salts of these compounds. These compounds can be used for maintaining the ability of human erythrocytes in stored blood, for example in blood banks, to supply oxygen. <IMAGE>
