  3-Alkylamino-4H-1,2,4-benzothiadiazine 1,1-Dioxides as ATP-Sensitive Potassium Channel Openers:  Effect of 6,7-Disubstitution on Potency and Tissue Selectivity

  摘要：

  A series of 6,7-disubstituted 4H-1,2,4-benzothiadiazine 1,1-dioxides bearing a short alkylamino side chain in the 3-position were synthesized. These compounds were tested on rat pancreatic islets and on rat aorta rings. In vitro data indicated that in most cases substitution in the 6 and the 7 positions increased their activity as inhibitors of insulin secretion, while the myorelaxant potency of the drugs was maintained or enhanced according to the nature of the substituent in the 7-position. The presence of either chlorine or bromine atoms in the 6 and 7 positions did not improve the apparent selectivity of the drugs for the pancreatic tissue. By contrast, the introduction of one or two fluorine atoms, as well as the presence of a methoxy group in the 7-position, generated potent and selective inhibitors of insulin release. Radioisotopic and fluorimetric experiments performed with the most potent compound inhibiting insulin release (34, BPDZ 259, 6-chloro-7-fluoro-3-isopropylamino-4H-1,2,4-benzothiadiazine 1,1-dioxide) confirmed that the drug activated K-ATP channels. 34 was found to be one of the most potent and selective pancreatic potassium channel openers yet described.

  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.
