  Tricyclic Pyrazoles. Part 1: Synthesis and Biological Evaluation of Novel 1,4-Dihydroindeno[1,2-c]pyrazol-based Ligands for CB1and CB2 Cannabinoid Receptors

  摘要：

  Cannabinoids receptors, cellular elements of the endocannabinoid system, have been the focus of extensive studies because of their potential functional role in several important physiological and pathological processes. To further evaluate the properties of CB receptors, especially CB1 and CB2 subtypes, we have designed, using SR141716A as a benchmark, a new series of rigid 1-aryl-1,4-dihydroindeno[1,2-c]pyrazole-3-carboxamides. Compounds I were synthesized from substituted 1-aryl-1,4-dihydroindeno[1,2-c]pyrazole-3-carboxylic acids and requisite amines. The various analogues were assayed for binding both to the brain and peripheral cannabinoid receptors (CB1 and CB2). Seven of the new compounds displayed very high in vitro CB2 binding affinities, especially 1a, 1b, 1c, 1e, 1g, 1h and 1j which showed K-i values of 0.34, 0.225, 0.27, 0.23, 0.385, 0.037 and 0.9 nM, respectively. Compounds 1a, 1b, 1c and 1h showed the highest selectivity for CB2 receptor with K-i(CB1) to K-i(CB2) ratios of 6029, 5635, 5814 and 9810, respectively. Noticeably, 1h exhibited the highest affinity and selectivity for CB2 receptors. (C) 2002 Elsevier Science Ltd. All rights reserved.

  Chromophore-modified bis-benzo[g]indole carboxamides: synthesis and antiproliferative activity of bis-benzo[g]indazole-3-carboxamides and related dimers

  摘要：

  Tricyclic pyrazole dimers that comprise two kinds of CONH-(CH(2))(n)-N(CH(3))-(CH(2))(n)-NHCO bridges to which are linked potential DNA-intercalating groups such as 1H-benzo[g]indazole, 2H-benzo[g]indazole and 1,4-dihydroindeno[1,2-c]pyrazole were designed, synthesized and some of them evaluated in vitro by NCI (Bethesda, USA) against nine types of cancer cells. Compounds 2a, 2f-i and 2o-r demonstrated significant antiproliferative activity, all with GI(50) values in the low micromolar range. Preliminary analysis of the structure-activity relationship for dimers 2 indicated that: (i) in the ground terms (2a and 2k) antitumor activities were strongly related to the type of chromophore, (ii) in contrast, either 1H-benzo[g]indazole- or 1,4-dihydroindeno[1,2-c]pyrazole-dimers when bore a N(1)-aryl group (2g, 2h, 2i, 2o, 2p, 2q and 2r) generally showed a good level of antitumor potency and (iii) for the most representative compounds (pairs of compounds: 2g,2h; 2o,2p and 2q,2r) the length of the bridges did not significantly contribute to the variations in cytotoxicity. Two members of this series, 2f and 2q, were selected and tested in the hollow fiber cell assay to evaluate in a preliminary fashion their in vivo antitumor activity. Finally, viscosity measurement of 2f with poly(dA-dT)(2), confirmed that these promising compounds behaved as typical DNA-intercalating agents.
