A structurally-diverse series of carboxylate derivatives based on the 1,2,5-thiadiazolidin-one 1,1 dioxide scaffold were synthesized and used to probe the S′ subsites of human neutrophil elastase (HNE) and neutrophil proteinase 3 (Pr 3).
Benzo[b]thiophenesulfonamide 1,1-dioxide derivatives (BTS) were described as candidate antineoplastic drugs.
The electrochemical behaviours of 2,2′-bipyridine-1-oxide, 2,2′-bipyridine-1,1′-dioxide, 4,4′- dihydroxy-2,2′-bipyridine-1,1′-dioxide and orellanine (3,3′,4,4′-tetrahydroxy 3,3′,4,4′-tetrahydroxydioxide) are described.
Here, we prepared 1,2-benzothiazine 1,1-dioxide acetic acid derivatives and investigated their inhibition activity.
Thus, the structure activity relationships of benzo[1.3.2]dithiazolium ylide 1,1-dioxide skeleton were carried out.
Peptide inhibitors that incorporated 3-oxotetrahydrofuran and 3-oxotetrahydrothiophene 1,1-dioxide groups had the highest activities.
Therefore, development of more powerful ARIs based on benzothiazine 1,1-dioxide by stereo-controlled synthesis could be expected.
HTZ is chemically named 6-chloro-3, 4-dihydro-7-sulfamoyl-2H-1, 2, 4-bezothiadiazine 1,1-dioxide, 6-chloro-3, 4-dihydro-2H-1, 2, 4-benzothiadiazine-7-sulfonamide 1,1-dioxide,6-chloro-7-sulfamyl-3, 4-dihydro-1, 2, 4 - benzothiadiazine 1,1-dioxide,2H-1 1,1-dioxide,2H-1 1,1-dioxide,2H-1ide, 6-chloro-3, 4-dihydro-1, 1-dioxide (Figure 1b).
Saccharin (1, 2-benzisothiazol-3(2H -one-1, 1-dioxide), (Figure 4) is a non-glucose, low-calorie sugar substitute.
As a result, benzo[1.3.2]dithiazolium ylide 1,1-dioxide represented a novel scaffold for the exploitation in developing dual COX-2/5-LOX inhibitors.
