Novel succinimides and maleimides are inhibitors of tumor necrosis factor .alpha. and phosphodiesterase and can be used to combat cachexia, endotoxic shock, retrovirus replication, asthma, and inflammatory conditions. A typical embodiment is methyl 3-(3',4',5',6'-tetrahydrophthalimido)-3-(3",4"-dimethoxyphenyl)propionate.

Succinimide and maleimide cytokine inhibitors

Certain amino-acid derivatives are disclosed as effective inhibitors of human leukocyte elastase and therefore useful in preventing the imbalance of this proteolytic enzyme in vivo. The compounds specifically are derivatives L-valine, L-norvaline, L-norleucine, and L-methionine methyl ester azolides succinimides or pyridones and sulfonate salts, and related compounds such as L-leucine and L-phenylalanine methyl ester derivatives. The compounds were found to be excellent inhibitors in that they embody both inhibitory and anti-oxidant or anti-inflammatory activity.

Latent isocynate derivatives useful for deactivating enzymes

The present invention includes N-substituted maleimides (1(H)-Pyrrole-2,5-dione (Maleimide) analogs and succinimides which act as potent nonsteroidal anti-inflammatory drugs and are capable of dual inactivation or selective inactivation of the cyclooxygenase and the peroxidase activities of prostaglandin endoperoxide synthase (PGHS).
