Modification with succinic anhydride of Clostridium perfringens epsilon prototoxin or toxin resulted in a loss of activation by trypsin or lethal activity, respectively. The prototoxin was more sensitive to succinylation than the toxin. On the other hand, the succinylated prototoxin was activated and cleaved by chymotrypsin, but not by trypsin. The lethal activity of the toxin was also lost after treatment with 2,3-dimethylmaleic anhydride or 2,4,6-trinitrobenzenesulfonic acid. When the 2,3-dimethylmaleic anhydride treated toxin treated with succinic anhydride or 2,4,6-trinitrobenzenesulfonic acid was incubated under acidic condition, it regained lethal activity. Thus modification of amino groups (lysine residues) prevented activation of the prototoxin by trypsin, and abolished lethal activity of the toxin.
THE MALEIC ANHYDRIDES, A SERIES OF REVERSIBLE ACYLATING AGENTS, PRODUCED THE ASPIRIN-TYPE DEFECT IN PLATELET AGGREGATION. UNLIKE THE ANTIPLATELET EFFECT OF ASPIRIN WHICH WAS IRREVERSIBLE, THE ANTIPLATELET EFFECT OF 2,3-DIMETHYLMALEIC ANHYDRIDE DISAPPEARED IN APPROXIMATELY 80 MINUTES AT 25 DEG.

使用2,3-Dimethylmaleic anhydride can be usually used in the synthesis of maleimides and as an amino group protecting agent for superoxide dismutase. It is also used in the preparation of dimethylmaleic acid dimethyl ester. Further, it serves as a reactant in the dissociation of ribosomal proteins. In addition to this, The isolated molecule 2, 3-dimethylmaleic anhydride showed potent insecticidal activity in fumigation bioassay against several insect species, viz., adults of houseflies, cockroaches and stored-product insects.
純化方法Distil the anhydride from *benzene/ligroin and sublime in a vacuum. [Beilstein 17/11 V 69.]

2,3-DIMETHYLMALEIC ANHYDRIDE, A REAGENT REMOVING POSITIVE CELL SURFACE CHARGES, DECREASED THE AGGREGATION OF CHICK EMBRYO NEURAL RETINA CELLS IN CULTURE. TWENTY-FOUR HOURS AFTER 2,3-DIMETHYLMALEIC ANHYDRIDE WAS REMOVED FROM THE MEDIUM, THE MOBILITIES OF THE CELLS WERE SIMILAR TO THOSE OF THE CONTROLS.

THE REACTION OF DIMETHYLMALEIC ANHYDRIDE WITH AMINO GROUPS AT SURFACE OF THE EGGS OF SEA URCHIN DID NOT PREVENT FERTILIZATION.
定義ChEBI: 2,3-Dimethylmaleic anhydride is a butenolide. It is a 5-membered cyclic anhydride with a double bond between carbon atoms C2 and C3. The double bond locks the molecule in a planar conformation and stabilizes the acid anhydride against hydration. It was used as linker to a cell penetrating peptidebased nanoparticle.
