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.

Described herein are heteroaryl compounds with estrogen receptor modulation activity or function having the Formula (I), (II), and (III) structures: and stereoisomers, tautomers, or pharmaceutically acceptable salts thereof, and with the substituents and structural features described herein. Also described are pharmaceutical compositions and medicaments that include the Formula I, II, and III compounds, as well as methods of using such estrogen receptor modulators, alone and in combination with other therapeutic agents, for treating diseases or conditions that are mediated or dependent upon estrogen receptors.
The subject invention provides an expedited synthesis of 5, 6, and 7-iodoindenes from the corresponding aminoindan-1-ones in more than 70% yield, employing readily available precursors and reagents. A three-step sequence involves diazotization-iodination of aminoindan-1-one followed by reduction and dehydration. The method has a general character and can be extended for the preparation of various 4-, 5-, 6- or 7-haloindenes using different halogen sources for diazotization-halogenation reaction.

described a new approach for the design of high–affinityCCR2antagonists, by taking their residence time (RT) on the receptor into account. Here, we report our findings on both structure–affinity relationship (SAR) and structure–kinetic relationship (SKR) studies for a series of 3-((inden-1-yl)amino)-1-isopropyl-cyclopentane-1-carboxamides as CCR2antagonists. SAR studies showed that this class of compounds

Medium‐ring natural products exhibit diverse biological activities but such scaffolds are underrepresented in probe and drug discovery efforts due to the limitations of classical macrocyclization reactions. We report herein a tandem oxidative dearomatization‐ring‐expanding rearomatization (ODRE) reaction that generates benzannulated medium‐ring lactams directly from simple bicyclic substrates. The
