Abstract
Adenosine A1/A2A receptors (A1R/A2AR) represent targets in nondopaminergic treatment of motor disorders such as Parkinson's disease (PD). As an innovative strategy, multitargeting ligands (MTLs) were developed to achieve comprehensive PD therapies simultaneously addressing comorbid symptoms such as sleep disruption. Recognizing the wake-promoting capacity of histamine H3 receptor (H3R) antagonists in combination with the "caffeine-like effects" of A1R/A2AR antagonists, we designed A1R/A2AR/H3R MTLs, where a piperidino-/pyrrolidino(propyloxy)phenyl H3R pharmacophore was introduced with overlap into an adenosine antagonist arylindenopyrimidine core. These MTLs showed distinct receptor binding profiles with overall nanomolar H3R affinities (Ki < 55 nM). Compound 4 (ST-2001, Ki (A1R) = 11.5 nM, Ki (A2AR) = 7.25 nM) and 12 (ST-1992, Ki (A1R) = 11.2 nM, Ki (A2AR) = 4.01 nM) were evaluated in vivo. l-DOPA-induced dyskinesia was improved after administration of compound 4 (1 mg kg-1, i.p. rats). Compound 12 (2 mg kg-1, p.o. mice) increased wakefulness representing novel pharmacological tools for PD therapy.

Novel indanone derivatives as MAO B/H 3R dual-targeting ligands for treatment of Parkinson's disease. Eur J Med Chem 2018; 148:487-497. [PMID: 29477889 DOI: 10.1016/j.ejmech.2018.02.015] [Citation(s) in RCA: 32] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2017] [Revised: 02/05/2018] [Accepted: 02/06/2018] [Indexed: 11/24/2022]
Abstract
The design of multi-targeting ligands was developed in the last decades as an innovative therapeutic concept for Parkinson's disease (PD) and other neurodegenerative disorders. As the monoamine oxidase B (MAO B) and the histamine H3 receptor (H3R) are promising targets for dopaminergic regulation, we synthetized dual-targeting ligands (DTLs) as non-dopaminergic receptor approach for the treatment of PD. Three series of compounds were developed by attaching the H3R pharmacophore to indanone-related MAO B motifs, leading to development of MAO B/H3R DTLs. Among synthesized indanone DTLs, compounds bearing the 2-benzylidene-1-indanone core structure showed MAO B preferring inhibition capabilities along with nanomolar hH3R affinity. Substitution of C5 and C6 position of the 2-benzylidene-1-indanones with lipophilic substituents revealed three promising candidates exhibiting inhibitory potencies for MAO B with IC50 values ranging from 1931 nM to 276 nM and high affinities at hH3R (Ki < 50 nM). Compound 3f ((E)-5-((4-bromobenzyl)oxy)-2-(4-(3-(piperidin-1-yl)propoxy)benzylidene)-2,3-dihydro-1H-inden-1-one, MAO B IC50 = 276 nM, hH3R Ki = 6.5 nM) showed highest preference for MAO B over MAO A (SI > 36). Interestingly, IC50 determinations after preincubation of enzyme and DTLs revealed also nanomolar MAO B potency for 3e (MAO B IC50 = 232 nM), a structural isomer of 3f, and 3d (MAO B IC50 = 541 nM), suggesting time-dependent inhibition modes. Reversibility of inhibition for all three compounds were confirmed by dilution studies in excess of substrate. Thus, indanone-substituted derivatives are promising lead structures for the design of MAO B/hH3R DTLs as novel therapeutic approach of PD therapy.

Abstract
A series of tetrahydroisoquinolines acting as dual serotonin transporter inhibitor/histamine H(3) antagonists is described. The introduction of polar aromatic spacers as part of the histamine H(3) pharmacophore was explored. A convergent synthesis of the final products allowing late stage introduction of the aromatic side chain was developed. In vitro and in vivo data are discussed.

Abstract
BACKGROUND AND PURPOSE Studies suggest that measurement of thermodynamic parameters can allow discrimination of agonists and antagonists. Here we investigate whether agonists and antagonists can be thermodynamically discriminated at histamine H(3) receptors. EXPERIMENTAL APPROACH The pK(L) of the antagonist radioligand, [(3)H]-clobenpropit, in guinea-pig cortex membranes was estimated at 4, 12, 21 and 30 degrees C in 20 mM HEPES-NaOH buffer (buffer A), or buffer A containing 300 mM CaCl(2), (buffer A(Ca)). pK(I)' values for ligands with varying intrinsic activity were determined in buffer A and A(Ca) at 4, 12, 21 and 30 degrees C. KEY RESULTS In buffer A, the pK(L) of [(3)H]-clobenpropit increased with decreasing temperature while it did not change in buffer A(Ca). The Bmax was not affected by temperature or buffer and n (H) values were not different from unity. In buffer A, pK(I)' values for agonists remained unchanged or decreased with decreasing temperature, while antagonist pK(I) values increased with decreasing temperature; agonist binding was entropy-driven while antagonist binding was enthalpy and entropy-driven. In buffer A(Ca), temperature had no effect on antagonist and agonist pK(I) values; both agonist and antagonist binding were enthalpy and entropy-driven. CONCLUSIONS AND IMPLICATIONS The binding of H(3)-receptor agonists and antagonists can be thermodynamically discriminated under conditions where agonist pK(I)' values are over-estimated (pK(I)' not = pK(app)). However, under conditions when agonist pK(I) approximately pK(app), the thermodynamics underlying the binding of agonists are not different to those of antagonists.

Abstract
4-[6-(2-Tertiaryaminoethyl)naphthalen-2-yl]benzonitriles are conformationally constrained histamine H3 receptor antagonists with high potency and selectivity. The analogs were designed around a naphthalene core, with the goal of enhancing lipophilicity and CNS penetration, as compared to a previously reported benzofuran series. The SAR of the tertiary amine moiety is similar to that reported for the benzofuran series, with analogs bearing a 2-methylpyrrolidine substituent possessing the greatest rat and human H3 receptor binding affinities.

Abstract
Antagonists of the histamine H(1) and H(2) receptors have been successful as blockbuster drugs for treating allergic conditions and gastric ulcers, respectively. As such, histamine receptors have made a significant contribution to establishing G-Protein-coupled receptors as the favored drug targets of the industry. In this light, it can easily be understood that the discovery of a third histamine receptor subtype (H(3)R) in 1983 was greeted with considerable excitement. However, characterization of the H(3)R turned out to be far from trivial. In the past five years, molecular biology approaches have given fresh impetus to the H(3)R research field. As a result, H(3)R ligands are where they were anticipated to be 20 years ago: at the center of attention and on the verge of an anticipated breakthrough as the next generation of histaminergic blockbuster drugs. Here, we assess the status of the H(3)R medicinal chemistry programs of the various players in the field, as far as can be deduced from patent applications and scientific literature.
