The relationship between stereochemical and both, pharmacological and ADME-Tox, properties of the potent hydantoin 5-HT 7R antagonist MF-8. Bioorg Chem 2020; 106:104466. [PMID: 33246603 DOI: 10.1016/j.bioorg.2020.104466] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2019] [Revised: 09/30/2020] [Accepted: 11/06/2020] [Indexed: 11/18/2022]
Abstract
This study concerns synthesis and evaluation of pharmacodynamic and pharmacokinetic profile for all four stereoisomers of MF-8 (5-(4-fluorophenyl)-3-(2-hydroxy-3-(4-(2-methoxyphenyl)piperazin-1-yl)propyl)-5-methylimidazolidine-2,4-dione), the previously described, highly potent 5-HT7R ligand with antidepressant activity on mice. The combination of DFT calculations of 1H NMR chemical shifts with docking and dynamic simulations, in comparison to experimental screening results, provided prediction of the configuration for one of two present stereogenic centers. The experimental data for stereoisomers (MF-8A-MF-8D) confirmed the significant impact of stereochemistry on both, 5-HT7R affinity and antagonistic action, with Ki and Kb values in the range of 3-366 nM and 0.024-99 μM, respectively. We also indicated the stereochemistry-dependent influence of the tested compounds on P-glycoprotein efflux, absorption in Caco-2 model, metabolic pathway as well as CYP3A4 and CYP2C9 activities.

Radiosynthesis and preclinical evaluation of [ 11 C]Cimbi-701 - Towards the imaging of cerebral 5-HT 7 receptors. J Labelled Comp Radiopharm 2020; 63:46-55. [PMID: 31674045 DOI: 10.1002/jlcr.3808] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2019] [Revised: 09/05/2019] [Accepted: 10/01/2019] [Indexed: 12/16/2022]
Abstract
The serotonin 7 (5-HT7 ) receptor is suggested to be involved in a broad variety of CNS disorders, but very few in vivo tools exist to study this important target. Molecular imaging with positron emission tomography (PET) would enable an in vivo characterization of the 5-HT7 receptor. However, no clinical PET radiotracer exists for this receptor, and thus we aimed to develop such a tracer. In this study, we present the preclinical evaluation of [11 C]Cimbi-701. Cimbi-701 was synthesized in a one-step procedure starting from SB-269970. Its selectivity profile was determined using an academic screening platform (NIMH Psychoactive Drug Screening Program). Successful radiolabeling of [11 C]Cimbi-701 and subsequent in vivo evaluation was conducted in rats, pigs and baboon. In vivo specificity was investigated by 5-HT7 and σ receptor blocking studies. P-gp efflux transporter dependency was investigated using elacridar. [11 C]Cimbi-701 could successfully be synthesized. Selectivity profiling revealed high affinity for the 5-HT7 (Ki = 18 nM), σ-1 (Ki = 9.2 nM) and σ-2 (Ki = 1.6 nM) receptors. In rats, [11 C]Cimbi-701 acted as a strong P-gp substrate. After P-gp inhibition, rat brain uptake could specifically be blocked by 5-HT7 and σ receptor ligands. In pig, high brain uptake and specific 5-HT7 and σ-receptor binding was found for [11 C]Cimbi-701 without P-gp inhibition. Finally, low brain uptake was found in baboons. Both the specific σ-receptor binding and the low brain uptake of [11 C]Cimbi-701 displayed in baboon discouraged further translation to humans. Instead, we suggest exploration of this structural class as results indicate that selective 5-HT7 receptor imaging might be possible when more selective non-P-gp substrates are identified.
