Suproclone is very similar in structure to the related drug suriclone, but little information has been published about it specifically. However it can be expected that the mechanism of action by which suproclone produces its sedative and anxiolytic effects is by modulating benzodiazepine receptors (resulting in an increased response to endogenous GABA), in a similar manner to other drugs of this class.[2][3]

Synthesis

edit
 
ChemDrug Synthesis:[4] Patent (Ex 1/15):[5]

The condensation between 2,3-Dihydro-1,4-dithiino[2,3-c]furan-5,7-dione [10489-75-5] (1) and 7-Chloro-1,8-naphthyridin-2-amine [15944-33-9] (2) gives PC23343647 (3). Halogenation with phosphoryl chloride leads to PC23343652 (4). Reductino with potassium borohydride afforded [53788-25-3] (5). Treatment with phenyl chloroformate [1885-14-9] (6) resulted in 2-(7-chloro-1,8-naphthyridin-2-yl)-3-phenoxycarbonyloxy-isoindolin-1-one, PC23343637 (7). Reaction with piperazine [110-85-0] (8) afforded (9). Acylation with propionyl chloride completed the synthesis of Suproclone (10).
