Watanabe M, Kobayashi T, Ito Y, Fukuda H, Yamada S, Arisawa M, Shuto S. Design and synthesis of histamine H 3/H 4 receptor ligands with a cyclopropane scaffold. Bioorg Med Chem Lett 2018; 28:3630-3633. [PMID: 30385161 DOI: 10.1016/j.bmcl.2018.10.041] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2018] [Revised: 10/19/2018] [Accepted: 10/24/2018] [Indexed: 12/27/2022]
Abstract
We previously designed and synthesized a series of histamine analogues with an imidazolylcyclopropane scaffold and identified potent non-selective antagonists for histamine H3 and H4 receptor subtypes. In this study, to develop H4 selective ligands, we newly designed and synthesized cyclopropane-based derivatives having an indole, benzimidazole, or piperazine structure, which are components of representative H4 selective antagonists such as JNJ7777120 and JNJ10191584. Among the synthesized derivatives, imidazolylcyclopropanes 12 and 13 conjugated with a benzimidazole showed binding affinity to the H3 and H4 receptors comparable to that of a well-known non-selective H3/H4 antagonist, thioperamide. These results suggest that the binding modes of the cyclopropane-based H3/H4 ligands in the H4 receptor can be different from those of the indole/benzimidazole-piperazine derivatives.

Abstract
Synthesis and biological evaluation of a new class of histamine H4 receptor ligands, distinct from the previously reported chemotypes, are described. A virtual screening of our corporate compound collection identified a hit with an undesired dual H3R/H4R activity. Chemical exploration led to the discovery of a more potent and selective 2-benzothiazolylphenylmethyl ether lead compound.

Abstract
Histamine is a chemical transmitter found practically in whole organism and exerts its effects through the interaction with H1 to H4 histaminergic receptors. Specifically, H4 receptors are found mainly in immune cells and blood-forming tissues, thus are involved in inflammatory and immune processes, as well as some actions in central nervous system. Therefore, H4 receptor ligands can have applications in the treatment of chronic inflammatory and immune diseases and may be novel therapeutic option in these conditions. Several H4 receptor ligands have been described from early 2000's until nowadays, being imidazole, indolecarboxamide, 2-aminopyrimidine, quinazoline, and quinoxaline scaffolds the most explored and discussed in this review. Moreover, several studies of molecular modeling using homology models of H4 receptor and QSAR data of the ligands are summarized. The increasing and promising therapeutic applications are leading these compounds to clinical trials, which probably will be part of the next generation of blockbuster drugs.
