3544-47-6

A compound of formula (I): which inhibits the activity of one or more KATs of the MYST family, i.e., TIP60, KAT6B, MOZ, HBO1 and MOF.

The invention generally relates to methods and compounds for treating proliferative disorders, viral infections, or both. In some embodiments, the invention provides an anticancer or antiviral compound including a substituted nitro phenoxy phenyl, a sulfonylurea, and an alkyl group. In some embodiments, the invention provides a method of treating a proliferative disorder or a viral infection including administering an anticancer or antiviral compound that binds to a thromboxane receptor, has preferential binding for either TPalpha (TPα) or TPbeta (TPβ) receptor subtype.

The synthesis of diversely substituted 3-alkyl/aralkyl/arylamino-1,4,2- benzodithiazine 1,1-dioxides and 3-alkylaminopyrido[4,3-e]-1,4,2-dithiazine 1,1-dioxides is described. Their biological activities on pancreatic β-cells and on smooth muscle cells were compared to those of the reference ATP-sensitive potassium channel (KATP channel) openers diazoxide and 7-chloro-3-isopropylamino-4H-1,2,4-benzothiadiazine 1,1-dioxide. The aim was to assess the impact on biological activities of the replacement of the 1,2,4-thiadiazine ring by an isosteric 1,4,2-dithiazine ring. Most of the dithiazine analogues were found to be inactive on the pancreatic tissue, although some compounds bearing a 1-phenylethylamino side chain at the 3-position exerted a marked myorelaxant activity. Such an effect did not appear to be related to the opening of KATP channels but rather reflected a mechanism of action similar to that of calcium channel blockers. Tightly related 3-(1-phenylethyl)sulfanyl-4H-1,2,4-benzothiadiazine 1,1-dioxides were also found to exert a pronounced myorelaxant activity, resulting from both a K ATP channel activation and a calcium channel blocker mechanism. The present work highlights the critical importance of an intracyclic NH group at the 4-position, as well as an exocyclic NH group linked to the 3-position of the benzo- and pyridothiadiazine dioxides, for activity on KATP channels.

The present work explored 3-alkylamino-4H-1,2,4-benzothiadiazine 1,1-dioxides diversely substituted in the 7-position. Those compounds, structurally related to previously described potassium channel openers such as the benzothiadiazine dioxide BPDZ 73, we
