  Synthesis and pharmacological evaluation of a series of dibenzo[a,d]cycloalkenimines as N-methyl-D-aspartate antagonists

  摘要：

  A series of 73 dibenzo[a,d]cycloalkenimines were synthesized and evaluated for their ability to displace (+)-10,11-dihydro-5-methyl-5H-dibenzo[a,d]cyclohepten-5,10-imine ([3H]-(+)-10) from its specific binding site on rat cortical membranes. A number of the more active compounds (Ki ranging from 0.006 to 0.21 microM) were evaluated for N-methyl-D-aspartate (NMDA) antagonist activity in the rat cortical slice (Kb ranging from 0.08 to 0.9 microM) and anticonvulsant activity in the mouse against NMDA induced convulsions. The ED50 values ranged from 0.22 to 7.76 mg/kg and correlated reasonably well with the Kb determination. In the dibenzo[a,d]cyclohepten-5,10-imine series, the (+)-5S,10R enantiomer displayed consistently higher levels of biological activity. While substitution at the 3-position of (+)-10 with electronegative atoms generally increased in vitro activity, a loss of potency relative to (+)-10 (MK-801) was observed in vivo for all of the compounds tested.

  Scalable Synthesis of Strained Cyclooctyne Derivatives

  摘要：

  Modifications to the Popik synthesis of aza-dibenzocyclooctyne (DIBAC) derivatives are described, which avoids tedious purifications and dramatically improves the yield. A new and analogous route to biarylazacyclooctynone (BARAC) through an amide disconnection was also attempted. The BARAC derivatives prepared were found to be unstable under the conditions employed, undergoing a known rearrangement. Finally, the synthesis of a difluoro-DIBAC derivative with a second-order rate constant intermediate between DIBAC and BARAC derivatives (0.50 M-1) is described. While more difficult to synthesize, this molecule was found to be considerably more stable than any BARAC derivatives that were prepared.
