ISOXAZOLIDINE DERIVED INHIBITORS OF RECEPTOR INTERACTING PROTEIN KINASE 1 (RIPK 1)

A combined computational and experimental investigation of the oxidative ring-opening of cyclic ethers by oxoammonium cations

The propensity of oxoammonium cations to facilitate the oxidative ring-opening of cyclic ethers to their corresponding distal hydroxy ketones is investigated. The reaction has been evaluated using experimental and computational methods to gain deeper insight into trends in reactivity.

Synthesis and in silico evaluation of novel compounds for PET-based investigations of the norepinephrine transporter

Since the norepinephrine transporter (NET) is involved in a variety of diseases, the investigation of underlying dysregulation-mechanisms of the norepinephrine (NE) system is of major interest. Based on the previously described highly potent and selective NET ligand 1-(3-(methylamino)-1-phenylpropyl)-3-phenyl-1,3-dihydro-2H-benzimidaz- ol-2-one (Me@APPI), this paper aims at the development of several fluorinated methylaminebased analogs of this compound. The newly synthesized compounds were computationally evaluated for their interactions with the monoamine transporters and represent reference compounds for PET-based investigation of the NET.

Lipase-catalyzed synthesis of both enantiomers of 3-chloro-1-arylpropan-1- ols

The lipase-catalyzed synthesis of both enantiomers of 3-chloro-1-(4- fluorophenyl)propan-1-ol, 3-chloro-1-(4-iodophenyl)propan-1-ol, and 3-chloro-1-phenylpropan-1-ol is described. The procedure is based on the enantiomer-selective acylation of the racemic alcohols in presence of lipase from Pseudomonas fluorescens (LAK) followed by the lipase from Candida rugosa (CRL) mediated hydrolysis of previously obtained enantiomerically enriched 1-aryl-3-chloropropyl esters. For the production of enantiopure (S)-1-aryl-3-chloropropan-1-ols (99% ee, 34-42% yield) the reactions were stopped at higher conversions than the theoretical optimum of 50%, while for enantiopure (R)-1-aryl-3-chloropropyl acetates (99% ee) the reactions were stopped at lower conversions. The latter compounds were enzymatically hydrolyzed into the corresponding (R)-1-aryl-3-chloropropan-1-ols (97-99% ee, 18-24% yield). The absolute configuration of the resolution products was determined by VCD measurements combined with quantum chemical calculations. Georg Thieme Verlag Stuttgart - New York.

1-[(3-Aryloxy-3-aryl)propyl]-1H-imidazoles, new imidazoles with potent activity against Candida albicans and dermatophytes. Synthesis, structure-activity relationship, and molecular modeling studies

New 1-[(3-aryloxy-3-aryl)propyl]-1H-imidazoles were synthesized and evaluated against Candida albicans and dermatophytes in order to develop structure-activity relationships (SARs). Against C. albicans the new imidazoles showed minimal inhibitory concentrations (MICs) comparable to those of ketoconazole, miconazole, and econazole, and were more potent than fluconazole. Several derivatives (10, 12, 14, 18-20, 24, 28, 29, 30, and 34) turned out to be potent inhibitors of C. albicans strains resistant to fluconazole, with MIC values less than 10 μg/mL. Against dermatophytes strains, compounds 20, 25, and 33 (MIC ≤ 5 μg/mL) were equipotent to ketoconazole, econazole, and miconazole. SARs of imidazoles 10-44 were rationalized with reasonable accuracy by a previously developed quantitative pharmacophore for antifungal agents.

Imidazole analogues of fluoxetine, a novel class of anti-Candida agents

Imidazole analogues of fluoxetine have been obtained by replacing the methylamino terminus of aminopropane chain with the imidazole ring. The newly designed imidazoles showed potent anti-Candida activity, superior to those of miconazole and other antifungal agents of clinical interest. 1-(4-Chlorophenyl)-l-(2,4-dichlorophenoxy)-3-(1H-imidazol-1-yl)propane (16), the most active among test imidazoles, Was about 2-fold more active and as much less cytotoxic than miconazole. High increase of activity was observed with methyl, nitro, fluorine, and chlorine (Cl > F > CH3 > NO2 > CF3).

Syntheses and Binding Studies of New [(Aryl)(aryloxy)methyl]piperidine Derivatives and Related Compounds as Potential Antidepressant Drugs with High Affinity for Serotonin (5-HT) and Norepinephrine (NE) Transporters

In a wide search program toward new, efficient, and fast-acting antidepressant drugs, we have prepared series of new compounds having an (aryl)(aryloxy)methyl moiety linked directly or through a methylene chain to different substituted and unsubstituted cycles (isoquinoline, piperazine, piperidine, tetrahydropyran, or cyclopentane). These compounds have been evaluated for their affinities for serotonin (5-HT) transporter (SERT) and 5-HT1A and 5-HT2A receptors. Racemic mixtures of 4-[(aryl)(aryloxy)methyl]piperidine derivatives showed much higher affinity values for SERT than fluoxetine and resulted in lack of affinity for 5-HT 1A and 5-HT2A receptors. Some of these racemic mixtures were resolved to their enantiomers and tested for binding to norepinephrine (NE) transporter (NET), dopamine (DA) transporter (DAT), and α2 receptor. Several of these enantiomers [(-)-15b, (-)-15j, (-)-15t, (+)-15u] displayed a dual binding profile with affinities for SERT and NET with K i i = 1.9 and 13.5 nM, respectively), and further pharmacological characterization is in progress for its evaluation as a antidepressant.

Asymmetric Synthesis of 2-Aryl Substituted Oxetanes by Enantioselective Reduction of β-Halogenoketones using Lithium Borohydride modified with N,N'-Dibenzoylcystine

Optically active 2-aryl substituted oxetanes are synthesised in high enantiomeric excesses (up to 89percent e.e.) via enantioselective reduction of β-halogenoketones with lithium borohydride using (R,R')-N,N'-dibenzoylcystine and t-butyl alcohols as ligands.
