especially good activity. Conformational restriction of either the polar region or lipid tail produced compounds devoid of activity. A number of selected analogues were also evaluated in vivo as antagonists of LTD4-induced bronchoconstriction in the guinea pig. The data established these compounds as a novelclass of leukotriene antagonists with potential utility for the treatment of asthma and other immediate

Cadmium(II) and zinc(II) complexes with the chelating agents meso-2,3-dimercapto succinic acid, meso-monomethyl dimercapto succinate, meso-dimethyl dimercapto succinate and the related methylmercapto acetate and mercapto succinic acid were studied potentiometrically in 0.1 M KCl at 25 degreesC. Models and hypotheses of coordination for the solution complexes are proposed. IR characterisation and stoichiometry of the solid state compounds evaluated by elemental analysis are presented. The obtained formation constants, together with the previously measured ionisation constants of the ligands, were used to compute pCd and pZn values and then to evaluate the effectiveness of the studied chelating agents in binding Cd(II) and Zn(II) in intoxication treatments.
