ABSTRACT
We describe the synthesis of four novel metabolically stabilized analogues of Ins(1,4,5)P(3) based on the known cyclopentane pentaol tris(phosphate) 2 tris(phosphorothioate) 3, tris(methylenephosphate) 4, tris(sulfonamide) 5, and tris(sulfate) 6. Of these analogues, only the tris(phosphorothioate) 3 and parent tris(phosphate) 2 bound to the type I InsP(3)R construct. In addition, both the tris(phosphorothioate) 3 and parent tris(phosphate) 2 elicited calcium release in MDA MB-435 breast cancer cells. The Ins(1,4,5)P(3) agonist activities of these two compounds can be rationalized on the basis of computational docking of the ligands to the binding domain of the type I InsP(3)R.
