Maryanoff BE, Costanzo MJ, Nortey SO, Greco MN, Shank RP, Schupsky JJ, Ortegon MP, Vaught JL: Structure-activity studies on anticonvulsant sugar sulfamates related to topiramate. J Med Chem. 1998 Apr 9;41(8):1315-43.
Cyclic sulfate 2, like topiramate and phenytoin, did not interfere with seizures induced by pentylenetetrazole, bicucculine, picrotoxin, and strychnine; also, 2 was not active in diverse in vitro receptor binding and uptake assays.
In this context, we have probed the pharmacological importance of several molecular features: (1) the sulfamate group (6-8, 22-25, 27, 84), (2) the linker between the sulfamate group and the pyran ring (9, 10, 21a,b), (3) the substituents on the 2,3- (58-60, 85, 86) and 4, 5-fused (30-38, 43, 45-47, 52, 53) 1,3-dioxolane rings, (4) the constitution of the 4,5-fused 1,3-dioxolane ring (2, 54, 55, 63-68, 76, 77, 80, 83a-r, 84-87, 90a, 91a, 93a), (5) the ring oxygen atoms (95, 96, 100-102, 104, 105), and (6) the absolute stereochemistry (106 and 107). |
