Synthesis and Pharmacological Evaluation of Novel Silodosin-Based Arylsulfonamide Derivatives as alpha(1A)/alpha(1D)-Adrenergic Receptor Antagonist with Potential Uroselective Profile

Benign prostatic hyperplasia (BPH) is the most common male clinical problem impacting the quality of life of older men. Clinical studies have indicated that the inhibition of alpha(1A)-/alpha(1D) adrenoceptors might offer effective therapy in lower urinary tract symptoms. Herein, a limited series of arylsulfonamide derivatives of (aryloxy)ethyl alicyclic amines was designed, synthesized, and biologically evaluated as potent alpha(1)-adrenoceptor antagonists with uroselective profile. Among them, compound 9 (3-chloro-2-fluoro-N-([1-(2-(2-(2,2,2-trifluoroethoxy)phenoxy]ethyl)piperidin-4-yl) methyl) benzenesulfonamide) behaved as an alpha(1A)-/alpha(1D)-adrenoceptor antagonist (K-i(alpha(1)) = 50 nM, EC50(alpha(1A)) = 0.8 nM, EC50(alpha(1D)) = 1.1 nM), displayed selectivity over alpha(2)-adrenoceptors (K-i(alpha(2)) = 858 nM), and a 5-fold functional preference over the alpha(1B) subtype. Compound 9 showed adequate metabolic stability in rat-liver microsome assay similar to the reference drug tamsulosin (Cl-int = 67 and 41 mu L/min/mg, respectively). Compound 9 did not decrease systolic and diastolic blood pressure in normotensive anesthetized rats in the dose of 2 mg/kg, i.v. These data support development of uroselective agents in the group of arylsulfonamides of alicyclic amines with potential efficacy in the treatment of lower urinary tract symptoms associated to benign prostatic hyperplasia.

Stereodivergent synthesis of piperidine iminosugars 1-deoxy-D-nojirimycin and 1-deoxy-D-altronojirimycin

A stereodivergent approach for producing piperidine iminosugars has been developed employing a common optically active precursor. The key steps of the synthetic pathway are the double diastereoselection in the asymmetric dihydroxylation of the suitable chiral vinyl epoxy ester and the regio- and stereospecific opening of the epoxide ring with azide. The synthesis of two piperidine iminosugars, 1-deoxy-D-altronojirimycin and 1-deoxy-D-nojirimycin, was achieved by two related routes. (C) 2020 Elsevier Ltd. All rights reserved.

Synthesis of N -substituted 3-(2-aryl-2-oxoethyl) 3-hydroxyindolin-2-ones and their conversion to N -substituted (E)-3-(2-aryl-2-oxoethylidene)indolin-2-ones: synthetic sequence, spectroscopic characterization and structures of four 3-hydroxy compounds and five oxoethylidene products

An operationally simple and time -efficient approach has been developed for the synthesis of racemic N-substituted 3-(2-aryl-2-oxoethyl)-3-hydroxyindolin-2ones by a piperidine-catalysed aldol reaction between aryl methyl ketones and N-alkylisatins. These aldol products were used successfully as strategic intermediates for the preparation of N-substituted (E)-3-(2-hetary1-2-oxoethylidene)indolin-2-ones by a stereoselective dehydration reaction under acidic conditions. The products have all been fully characterized by ‘H and 13C NMR spectroscopy, by mass spectrometry and, for a representative selection, by crystal structure analysis. In each of (RS)-1-benzy1-3-hydroxy 3 [2 (4 methoxypheny1)-2-oxoethyl]indolin-2-one, C24H21N04, (Ic), and (RS)-1-benzy1-3-{214(dimethylamino)pheny11-2-oxoethyll-3-hydroxyindolin-2-one, C25H24N203, (Id), inversion -related pairs of molecules are linked by 0 H 0 hydrogen bonds to form R22(10) rings, which are further linked into chains of rings by a combination of C H 0 and C H -7r(arene) hydrogen bonds in (Ic) and by C H rr(arene) hydrogen bonds in (Id). The molecules of (RS)-1-benzy1-3-hydroxy-3[2-oxo-2-(pyridin-4-yl)ethyl]indolin-2-one, C22Hi8N203, (Ie), are linked into a three-dimensional framework structure by a combination of 0 H -N, C H- 0 and C H -7r(arene) hydrogen bonds. (RS)-342-(Benzo[d][1,3]dioxo1-5y1)-2-oxoethy11-1-benzyl-3-hydroxyindolin-2-one, C24Hi9N05, (If), crystallizes with Z = 2 in the space group Pi and the molecules are linked into complex sheets by a combination of 0 H -0, C H 0 and C H -7r(arene) hydrogen bonds. In each of (E)-1-benzyl 3 [2 (4 fluoropheny1)-2-oxoethylidene]indolin-2one, C23H16FN02, (Ha), and (E)-1-benzy1-342-oxo-2-(thiophen-2-yl)ethylidene1indolin-2-one, C2iH15NO2S, (llg), the molecules are linked into simple chains by a single C H 0 hydrogen bond, while those of (E)-1-benzy1-342-oxo-2-(pyriclin4-yl)ethylidenelindolin-2-one, C22Hi6N202, (He), are linked by three C H 0 hydrogen bonds to form sheets which are further linked into a three-dimensional structure by C H -7r(arene) hydrogen bonds. There are no hydrogen bonds in the structures of either (E)-1-benzy1-342-(4-methoxypheny1)-2-oxoethylidene1indolin-2-one, C24Hi9NO3, (IIc), or (E)-1-benzy1-5-chloro 3 [2 (4 chloropheny1)-2oxoethylidene]indolin-2-one, C23H15C12NO2, (IIh), but the molecules of (IIh) are linked into chains of rr-stacked dimers by a combination of C Cl -7r(arene) and aromatic 7r rr stacking interactions.

Recent developments in the synthesis of prosophylline and its derivatives

Several synthetic efforts are reported towards the optically active (-)-prosophylline and (+)-prosophylline, and their derivatives. Interestingly and surprisingly, although only a few synthesis are reported for the parent molecules, there are more reports for the synthesis of their derivatives such as deoxoprosophyllines, deoxoprosopinines, deoxocassines etc. The three main strategies to procure these molecules in optically pure forms are by using (i) chiral synthons (ii) chiral auxiliaries and (iii) asymmetric catalysis. Among these, the chiral synthons are mainly utilized by a number of researchers. This review summarizes the recent developments in the synthesis of optically active prosophyllines and their derivatives, and covers the literature from the year 2000 onwards.

Comparative Genotoxicity of TEMPO and 3 of Its Derivatives in Mouse Lymphoma Cells

TEMPO (2, 2, 6, 6-tetramethylphiperidine-1-oxyl) and its derivatives are stable free radical nitroxides widely used in the field of chemistry, biology, and pharmacology. TEMPO was previously found to be mutagenic and to induce micronuclei in mammalian cells. In this study, we investigated and quantified the genotoxicity of 4 structurally similar nitroxides, TEMPO and 3 of its derivatives (4-hydroxy-TEMPO, 4-oxo-TEMPO, and 4-methoxy-TEMPO), using the mouse lymphoma assay (MLA) and Comet assay in L5178Y Tk(+/-) cells. The results showed that all tested nitroxides were cytotoxic and mutagenic in the MLA, both in the presence and absence of S9, with metabolic activation significantly enhancing the cytotoxicity and/or mutagenicity. In addition, the 4 nitroxides caused DNA-strand breakage. The mutagenicity and DNA damaging dose-responses of the test articles were compared using the PROAST benchmark dose software package. The potency ranking of the 4 nitroxides for mutagenicity was different from the ranking of the DNA damaging effects. The mode of action analysis by a multi-endpoint DNA damage pathway assay classified all 4 nitroxides as clastogens. In addition, the majority of the induced Tk mutants showed loss of heterozygosity at the Tk and D11Mit42 loci (ie, chromosome damage <31 Mbp). These results suggest that TEMPO and its 3 derivatives are cytotoxic and mutagenic in mouse lymphoma cells through a mechanism that involves strand breakage and large alterations to DNA. The potency rankings indicate that the different TEMPO derivatives vary in their mutagenic and DNA damaging potential. Interested yet?

Voltammetric behaviour of the anticancer drug irinotecan and its metabolites in acetonitrile. Implications for electrochemical therapeutic drug monitoring

In this paper the voltammetric behaviour of the anticancer drug irinotecan (CPT-11), its injectable form in the clinical treatment regimen, irinotecan hydrochloride (CPT-11HCl), and its main metabolites (namely SN-38, SN-38G, APC, and NPC), and the natural chemical analogous camptothecin (CPT) were investigated in acetonitrile using a glassy carbon electrode (GCE), in view of developing an analytical protocol for the therapeutic drug monitoring (TDM) of CPT-11 in patients under chemotherapy regimens. Our results showed that all compounds provided rather complex cyclic voltammetric (CV) patterns in both the negative and positive potential regions. The overall results indicated that the processes recorded in the negative potential region at both GCE and Pt electrodes could be hardly exploited for TDM applications, because of the overlapping of the peaks. Instead, in the positive potential region, the oxidation of the piperidine moiety of CPT-11, which was obtained in CPT-11HCl acetonitrile solutions basified with Na2B4O7 (synthetic solutions), proved to be useful for irinotecan quantification, as its process at the GCE took place over a potential region essentially free from interference. Preliminary differential pulse voltammetry (DPV) measurements performed in synthetic solutions of CPT-11HCl, over the concentration range 0.2-9 mu M, showed a linear dependence between peak current and concentration with a satisfactory correlation coefficient of 0.992. The reproducibility was within 5% from three replicates. (C) 2018 Elsevier Ltd. All rights reserved.

CONVENTIONAL AND MICROWAVE ASSISTED SYNTHESIS OF SOME NEW DERIVATIVES OF COUMARIN CONTAINING PYRAZOLINE AND INVESTIGATION OF THEIR ANTIBACTERIAL AND ANTIFUNGAL ACTIVITIES

Pyrazoline derivatives, being used as potential medicinal agents, 3-Acetyl-2H-chromen-2one (I) was prepared by Knoevenagel condensation of salicyladehyde with ethylacetoacetate in presence of piperidine. A series of 3-[(2E)-3-substituted-prop-2-enoyl]-2H-chro men-2-one derivatives (II a-h) were prepared by Claisen-Schmidt condensation of 3-acetyl coumarin with aromatic aldehydes. Treatment of 3-substituted cinnamoylcoumarin with hydrazine hydrate in the presence of ethanol gave [5-substitutedphenyl]-4, 5-dihydro-1Hpyrazol- 3-yl]-2H-chromen-2-one (III a-h). Title compound were synthesized by conventional as well as by microwave assisted method. The structures of the newly synthesized compounds were confirmed by IR and 1H-NMR spectroscopy. All the synthesized compounds were tested for their antibacterial and antifungal activities using cupplate- agar-diffusion method. The antibacterial activity screening revels that the compound III b has comparable activity and compound III c shows moderate activity as that of standard ampicillin against gram positive and gram negative bacteria. All synthesized compounds were found to be inactive as antifungal against Candida albicans.

Prepared poly(aryl piperidinium) anion exchange membranes for acid recovery to improve dialysis coefficients and selectivity

The diffusion dialysis (DD) process based on AEM is considered for the acid recovery from acid effluents. In this work, the novel self-organized nanostructured cross-linked AEMs based on poly (aryl piperidinium) are synthesized for acid recovery. The cross-linked AEMs are designed by introducing 2-bromoethanol and 1,6-dibromohexane into the hydrophobic poly (biphenyl piperidine)s backbone via Menshutkin reaction, and the self-assembled nanostructure is confirmed by TEM imagines. The acid flux is improved by constructing a microphase separation structure and hydrogen bond network. The H-bond networks and cross-linking structure improve the selectivity between the acid and salt system without sacrificing IEC values of AEM. The IEC values of PBP-OH-x AEMs are in the range of 2.18-2.21 mmol/g. The AEMs exhibit high H+ dialysis coefficients (U-H), ranging from 0.045 to 0.053 m/h, and have good separation factors (S) in the range of 32-56. The prepared PBP-OH-x AEMs have better DD performance, comparing with the commercial membrane DF-120 (U-H = 0.009 m/h, S = 18.5). The novel AEMs based on poly (aryl piperidinium) showed the potential to be used in acid recovery via DD.

Synthetic Pathways to 3,4,5-Trihydroxypiperidines from the Chiral Pool

3,4,5-Trihydroxypiperidines represent a family of biologically active natural products, found to modulate principally the glycosidase enzymes. This is ascribed to their structural and electronic resemblance to the pyranose monosaccharides, their natural counterparts. Expedient syntheses are crucial to access these valuable high Fsp(3) index drug leads. In this review we present the literature strategies to this class of iminosugars to spur further research into drug leads targeting the glycobiological machinery of living systems.

Low molecular weight hindered amine light stabilizers (HALS) intercalated MgAl-Layered double hydroxides: Preparation and anti aging performance in polypropylene nanocomposites

A low molecular weight hindered amine light stabilizer (HALS), contains 2, 2, 6, 6-tetramethyl piperidine functional group has been successfully prepared and intercalated into the interlayer region of Mg-Al layered double hydroxides (LDH) via a co-precipitation method to produce HALS-LDH. Furthermore, a series of HALS-LDH/PP nanocomposites were fabricated by dispersing HALS-LDH in poly(propylene) (PP) in a solvent casting route. Through the accelerated aging test method, the morphological properties, the thermal-oxidative degradation and photo-oxidative degradation behavior of HALS-LDH/PP composites were carefully investigated. The results show that the thermal stability of HALS in HALS-LDH was improved compared to that of HALS free of LDH dispersed into PP, and there is no negative effect on the crystallization behavior of PP after the addition of HALS-LDH. Besides, the HALS-LDH significantly enhances synergistically the thermal- and photo-stability of PP compared when LDH platelets CO3-LDH or HALS are used separately. Under the experimental conditions, a mass loading of HALS-LDH optimized as 4 wt % in respect to PP was found to exhibit an excellent anti-aging performance for potential applications.
