Adamantanyl benzamide 1 was identified as a potent P2X7R antagonist but failed to progress further due to poor metabolic stability. We describe the synthesis and SAR of a series of bioisosteres of benzamide 1 to explore improvements in the pharmacological properties of this lead. Initial efforts investigated a series of heteroaromatic bioisosteres, which demonstrated improved physicochemical properties but reduced P2X7R antagonism. Installation of bioisosteric fluorine on the adamantane bridgeheads was well tolerated and led to a series of bioisosteres with improved physicochemical properties and metabolic stability. Trifluorinated benzamide 34 demonstrated optimal physicochemical parameters, superior metabolic stability (ten times longer than lead benzamide 1), and an improved physicokinetic profile and proved effective in the presence of several known P2X7R polymorphisms.

A compound shown by the following formula: ???wherein each of R1a, R2a, R3aand R4arepresents a substituent selected from a non-reactive atom, a non-reactive group, a hydroxyl group and an amino group, and at least two members selected from R1a, R2a, R3aand R4aare a hydroxyl group, a carboxyl group or an amino group; is subjected to an esterification reaction or an amidation reaction with a polymerizable unsaturated compound (e.g., an alcohol, a carboxylic acid, an amine) in the presence of a catalyst comprising an element selected from the Group 3 elements, such as a samarium compound, to obtain a polymerizable adamantane derivative having at least one polymerizable unsaturated group in high yield.
