  Linear and proximal benzo-separated alkylated xanthines as adenosine-receptor antagonists

  摘要：

  The linear and proximal benzo-separated derivatives of 8-phenyltheophylline, 1,3-diethyl-8-phenylxanthine, 1,3-dipropylxanthine, 1,3-dibutylxanthine, 3-isobutyl-1-methylxanthine, theophylline, caffeine, and isocaffeine have been synthesized and evaluated for affinity at the A1 and A2 adenosine receptors. Although structure-activity relationships in the benzo-separated series differed from the relationships in the simple xanthines, the most potent of the benzo-separated xanthines were about equal in affinity to the most potent of the corresponding xanthines. On the basis of the present results and the diverse structures reported in the literature as non-xanthine adenosine antagonists, it appears that the primary requirement for adenosine-receptor affinity in nonnucleosides is a flat, neutral, fused-ring heterocycle and that once this requirement is met there are numerous potential binding modes.

  (QTOs) was synthesized and evaluated for antagonism of NMDA receptor glycine site. Glycine site affinity was determined using a [3H]DCKA binding assay in rat brain membranes and electrophysiologically in Xenopus oocytes expressing 1a/2C subunits of cloned rat NMDA receptors. Selected compounds were also assayed for antagonism of AMPA receptors in Xenopus oocytes expressing rat brain poly-(A)+RNA. QTOs

  The ester derivatives of salicylic acid and some kinds of anthranilic acid were reduced to corresponding alcohols with sodium borohydride. The reduction behavior of 4-oxo-1, 3-benzodioxanes (IXa-b), 1, 2-dihydro-4-oxo-3, 1-benzoxazines (XIIa-c, e, k) and 4-oxo-3, 1-benzoxazines (XVd-j) were also investigated. These results may be explained in terms of the contribution of the electronic structure of carbonyl group or the neighbouring participation of hydroxyl or amino group.

• Inhibition of cyclic nucleotide phosphodiesterases from pig coronary artery by benzo-separated analogs of 3-isobutyl-1-methylxanthine

  The linear and proximal benzo-separated analogues of 7-benzyl-3-isobutyl-1-methylxanthine, 3-isobutyl-1,8-dimethylxanthine, 3-isobutyl-8-tert-butyl-1-methylxanthine, 3-isobutyl-8-(methoxymethyl)-1-methylxanthine , and 1-isoamyl-3-isobutylxanthine have been prepared and assayed as inhibitors of the peak I and peak II forms of cyclic nucleotide phosphodiesterase from pig coronary artery. Most of the benzo analogues were less effective inhibitors of these phosphodiesterases when compared to 3-isobutyl-1-methylxanthine (IBMX) even though the active sites of both enzyme forms tolerated the stretched-out xanthines. Indeed, the linear benzo-separated analogue of 7-benzyl-IBMX was a more potent inhibitor of peak I activity than was IBMX.
