  The synthesis of diversely substituted 3-isopropoxy-, 3-isopropylsulfanyl-, 3-isopropylsulfinyl-, and 3-isobutyl-4H-1,2,4-benzothiadiazine 1,1-dioxides is described. Their activity on pancreatic β-cells (inhibitory effect on the insulin releasing process) and on vascular and uterine smooth muscle tissues (myorelaxant effects) was compared to that of previously reported KATP channel openers belonging

  Diversely substituted 3-isopropylamino-4H-1,2,4-benzothiadiazine 1,1-dioxides are known to be potent K-ATP channel openers, with several drugs being selective for the SUR1/Kir6.2 channel subtype. This work examined the biological activity, tissue selectivity, and in vitro metabolic stability of hydroxylated analogues of 3-isopropylaminobenzothiadiazine dioxides. Because of the presence of a chiral center, the R and S isomers were prepared separately and characterized. R isomers were systematically found to be more potent and more selective than S isomers on pancreatic tissue (compared to vascular smooth muscle tissue), leading to compounds with an improved sulfonylurea receptor 1 (SUR1) selectivity. An in vitro metabolic study revealed that 7-chloro-3-isopropylamino-4H-1,2,4-benzothiadiazine 1,1-dioxide (1a) was rapidly biotransformed and led in part to a mixture of the corresponding (R)- and (S)-3-(1-hydroxy-2-propyl)amino-substituted derivatives. Radioisotopic experiments characterized one of the most potent and SUR1-selective enantiomers, (R)-7-chloro-3-(1-hydroxy-2-propyl)amino-4H-1,2,4-benzothiadiazine 1,1-dioxide 13a, as being a K-ATP channel opener. Moreover, 13a exhibited an enhanced metabolic stability. Such a compound can be considered as a new lead candidate displaying improved physicochemical (hydrosolubility) and pharmacological (tissue selectivity) properties as well as improved metabolic stability compared to its nonhydroxylated counterpart, 1a.

• Aminomethyl-1,2,4-benzothiadiazines as potential analogs of .gamma.-aminobutyric acid. Unexpected discovery of a taurine antagonist

  A series of 6- and 8-(aminomethyl)-4H-1,2,4-benzothiadiazine 1,1-dioxides has been synthesized and tested for interaction with various GABA systems. None of the compounds showed significant GABA-mimetic properties, but unexpectedly, compound 7 [6-(aminomethyl)-3-methyl-4H-1,2,4-benzothiadiazine 1,1-dioxide] possessed the properties of a selective antagonist of taurine, as measured by the antagonism of taurine-induced inhibition of rat cerebellar Purkinje firing.
