- Discovery of Novel pERK1/2- or β-Arrestin-Preferring 5-HT1AReceptor-Biased Agonists: Diversified Therapeutic-like versus Side Effect Profile
-
Novel 1-(1-benzoylpiperidin-4-yl)methanamine derivatives with high affinity and selectivity for serotonin 5-HT1A receptors were obtained and tested in four functional assays: ERK1/2 phosphorylation, adenylyl cyclase inhibition, calcium mobilization, and β-arrestin recruitment. Compounds 44 and 56 (2-methylaminophenoxyethyl and 2-(1H-indol-4-yloxy)ethyl derivatives, respectively) were selected as biased agonists with highly differential "signaling fingerprints"that translated into distinct in vivo profiles. In vitro, 44 showed biased agonism for ERK1/2 phosphorylation and, in vivo, it preferentially exerted an antidepressant-like effect in the Porsolt forced swimming test in rats. In contrast, compound 56 exhibited a first-in-class profile: it preferentially and potently activated β-arrestin recruitment in vitro and potently elicited lower lip retraction in vivo, a component of "serotonergic syndrome". Both compounds showed promising developability properties. The presented 5-HT1A receptor-biased agonists, preferentially targeting various signaling pathways, have the potential to become drug candidates for distinct central nervous system pathologies and possessing accentuated therapeutic activity and reduced side effects.

- Synthesis and Investigation of S-Substituted 2-Mercaptobenzoimidazoles as Inhibitors of Hedgehog Signaling
-
Due to the arising resistance of common drugs targeting the Hedgehog signaling pathway, the identification of new compound classes with inhibitory effect is urgently needed. We were able to identify S-alkylated 2-mercaptobenzoimidazoles as a new compound

- DOPAMINE D2 RECEPTOR LIGANDS
-
The present invention relates to novel dopamine D2 receptor ligands. The invention further relates to functionally-biased dopamine D2 receptor ligands and the use of these compounds for treating or preventing central nervous system and systemic disorders associated with dysregulation of dopaminergic activity. The present invention relates to novel compounds that modulate dopamine D2 receptors. In particular, compounds of the present invention show functional selectivity at the dopamine D2 receptors and exhibit selectivity downstream of the D2 receptors, on the 0- arrestin pathway and/or on the cAMP pathway.

- Synthesis of new (arylcarbonyloxy)aminopropanol derivatives and the determination of their physico-chemical properties
-
Eight hydrochlorides of 3-{2-[(2/4-fluorophenoxy)-ethylamino]}-2- hydroxypropyl-4-alkoxybenzoates and four hydrochlorides of 3-tert-butylamino-2- hydroxypropyl-4-butoxybenzoates were prepared as potential antagonists of the β1-adrenergic receptor (beta-blockers). A multistep synthesis of these compounds is described as well as their detailed analytical characterization. The pharmacokinetic properties of these weak base compounds are significantly influenced by their acid-base dissociation constant, pK a. The knowledge of this value is crucial for new drug development. This paper is aimed at developing a methodology that utilizes pH-dependent 1H NMR spectroscopy for its routine analysis. The selected predicted physico-chemical parameters of the new (arylcarbonyloxy)aminopropanols (i.e., aryloxyaminopropanol derivatives) were compared with the model drugs esmolol and flestolol.

- Two-fragment α-adrenolytics 4. Synthesis of phosphorylated derivatives of 2-aryloxyethylamines and N-phenylpiperazine
-
The reactions of 3-chloropropylphosphonates, 3-chloropropylthiophosphonates, or 3-chloropropylphosphinates with 2-aryloxyethylamines or N-phenylpiperazine afford the corresponding 3-(2-aryloxyethylamino)propylphosphonates and -phosphinates or 3-(4-phenylpiperazin-1-yl)propylphosphonates and -phosphinates. The compounds obtained exhibit α-adrenolytic and hypotensive activities, the latter being found to depend on the substituents at the P atom.

- A simple modification of the known preparation procedure of 2-Phenoxyethyl bromides providing high yields
-
A modification of preparation method was developed for synthesis of a number of 1-bromo-2-phenoxyethanes from 1,2-dibromoethanes and sodium phenolates in two-phase water-organic system with or without addition of triethylbenzylammonium chloride as phase-transfer catalyst. Addition of NaOH in two portions for transforming phenols into phenolates ensured high yields (60-80%) of phenoxylation products.
