Synthesis and HPLC-ECD Study of Cytostatic Condensed O,N-Heterocycles Obtained from 3-Aminoflavanones

Racemic chiral O,N-heterocycles containing 2-arylchroman or 2-aryl-2H-chromene subunit condensed with morpholine, thiazole, or pyrrole moieties at the C-3-C-4 bond were synthesized with various substitution patterns of the aryl group by the cyclization of cis- or trans-3-aminoflavanone analogues. The 3-aminoflavanone precursors were obtained in a Neber rearrangement of oxime tosylates of flavanones, which provided the trans diastereomer as the major product and enabled the isolation of both the cis- and trans-diastereomers. The cis- and trans-aminoflavanones were utilized to prepare three diastereomers of 5-aryl-chromeno[4,3-b][1,4]oxazines. Antiproliferative activity of the condensed heterocycles and precursors was evaluated against A2780 and WM35 cancer cell lines. For a 3-(N-chloroacetylamino)-flavan-4-ol derivative, showing structural analogy with acyclic acid ceramidase inhibitors, 0.15 mu M, 3.50 mu M, and 6.06 mu M IC50 values were measured against A2780, WM35, and HaCat cell lines, and apoptotic mechanism was confirmed. Low micromolar IC50 values down to 2.14 mu M were identified for the thiazole- and pyrrole-condensed 2H-chromene derivatives. Enantiomers of the condensed heterocycles were separated by HPLC using chiral stationary phase, HPLC-ECD spectra were recorded and TDDFT-ECD calculations were performed to determine the absolute configuration and solution conformation. Characteristic ECD transitions of the separated enantiomers were correlated with the absolute configuration and effect of substitution pattern on the HPLC elution order was determined.

Novel synthesis of2-Aminothiazolesvia Fe(III)-Iodine-catalyzed Hantzsch-type condensation

A novel iron-iodine catalyzed one pot synthesis of 2-aminothiazoles from methyl aryl ketones and thiourea is demonstrated. This protocol can be considered as a catalyzed version of the classical Hantzsch aminothiazole synthesis as it enables the in situ generation of alpha-iodoketones in the reaction medium using catalytic amount of iodine leading to Hantzsch condensation with thiourea. The supply of iodine for multiple catalytic cycles is ensured by using catalytic amounts of iron as it enables iodide to iodine oxidation. The generality of this protocol is also well established in this manuscript by synthesizing a variety of 2-aminothiazoles from different ketones and thiourea.

Aryl Hydrocarbon Receptor Activity in Hepatocytes Sensitizes to Hyperacute Acetaminophen-Induced Hepatotoxicity in Mice

BACKGROUND & AIMS: Acetaminophen (APAP)-induced liver injury is one of the most common causes of acute liver failure, however, a dear definition of sensitizing risk factors is lacking. Here, we investigated the role of the ligand-activated transcription factor aryl hydrocarbon receptor (Ahr) in APAP-induced liver injury. We hypothesized that Ahr, which integrates environmental, dietary, microbial and metabolic signals into complex cellular transcriptional programs, might act as a rheostat for APAP-toxicity. METHODS: Wildtype or conditional Ahr knockout mice lacking Ahr in hepatocytes (Alb(Delta/Delta Ahr)) or myeloid cells (LysM(Delta/Delta Ahr)) were treated with the specific Ahr ligand 2-(1’H-indole-3′-carbonyl)-thiazole-4-carboxylic acid methyl ester (ITE) together with APAP. RESULTS: Ahr activation by ITE, which by itself was non-toxic, exacerbated APAP-induced hepatotoxicity compared to vehicle-treated controls, causing 80% vs. 0% mortality after administration of a normally sublethal APAP overdose. Of note, Ahr activation induced hepatocyte death even at APAP doses within the therapeutic range. Aggravated liver injury was associated with significant neutrophil infiltration; however, lack of Ahr in myeloid cells did not protect LysM(Delta/Delta Ahr) mice from exacerbated APAP hepatotoxicity. In contrast, Alb(Delta/Delta Ahr) mice were largely protected from ITE-induced aggravated liver damage, indicating that Ahr activation in hepatocytes, but not in myeloid cells, was instrumental for disease exacerbation. Mechanistically, Ahr activation fueled hepatic accumulation of toxic APAP metabolites by up-regulating expression of the APAP-metabolizing enzyme Cyp1a2, a direct Ahr downstream target. CONCLUSIONS: Ahr activation in hepatocytes potentiates APAP-induced hepatotoxicity. Thus, individual exposition to environmental Ahr ligands might explain individual sensitivity to hyperacute liver failure.

Synthesis and In Vitro Antitumor Evaluation of Some Carbazole-Based Thiazole, Thiophene, and 1,3,4-Thiadiazole Derivatives

In continuation to our efforts to discover new powerful antitumor agents, a series of new carbazole-based thiazole, thiophene, and 1,3,4-thiadiazole derivatives were conveniently synthesized, spectrally characterized, and mechanistically discussed. The synthetic strategy involves the cyclization reactions of two easily attainable commencing materials,N-(9-ethylcarbazol-3-yl)-2-cyanoacetamide (1) and 2-((9-ethylcarbazol-3-yl)hydrazono)-3-oxo-N-phenylbutanethioamide (20), with alpha-chlorocarbonyl reagents, alpha-chloronitrile, and hydrazonoyl chlorides in a basic medium. They were also assessed against three human tumor cell lines (HCT-116, HepG-2, and MCF-7) and one non-tumor human cell line (REP1) for their in vitro antitumor activity. The results demonstrated that seven carbazoles4,15 a,15 b,15 d,20,22 b, and29 ahad high antitumor activity, having IC(50)values in the range 5.24-9.70 mu M. The most potent carbazoles15 b,20and22 binhibited the growth of all tested tumor cell lines and did not display human toxicity.

Synthesis and Characterization of New Dihydronaphthalene Candidates as Potent Cytotoxic Agents against MCF-7 Human Cancer Cells

In the present work, a new series of dihydronaphthalene derivatives were synthesized starting with 6-methoxy-1-tetralone 1, and the corresponding hydrazine derivative 2. Reaction of compound 2 with aryl isothiocyanates produced thiosemicarbazides 3a-d, which were reacted with ethyl chloroacetate to give thiazolidinone derivatives 4a-d. Pyrano thiazolecarbonitrile derivatives 5a-f were prepared by heating a mixture of compounds 4a or 4c, aryl aldehydes, and malononitrile utilizing distilled water in the presence of catalytic amount of potassium hydrogen phthalate. Also, treatment of 4a with DMF-DMA under solvent-free conditions gave enaminone derivative 6, which condensed with ethyl acetoacetate or acetylacetone or malononitrile or cyanothioacetamide to give compounds 7-10, respectively. Finally, reaction of the enaminone 6 with 2-aminoimidazol or 2-aminothiazol in the presence of glacial acetic acid produced derivatives 11 and 12, respectively. Cytotoxic evaluation of eleven compounds, against MCF-7 (human breast adenocarcinoma) cell lines, was estimated. Results revealed that five of the examined compounds 5a, 5d, 5e, 10, and 3d showed potent cytotoxic activities recording, IC50 values; 0.93 +/- 0.02, 1.76 +/- 0.04, 2.36 +/- 0.06, 2.83 +/- 0.07, and 3.73 +/- 0.09 mu M, respectively, which were more potent than the reference used (Saturosporin, IC(50)6.08 +/- 0.15 mu M). The new products were also examined towards normal epithelial breast cells (MCF10A). All of them showed very good safety profile with different degrees and were safer than the reference drug used. Compound 5a was the most effective against MCF-7 cells and was less toxic than Saturosporin by about 18.45-folds towards MCF01A normal cells. All the new compounds were fully characterized by the different spectral and analytical tools. Herein, detailed syntheses, spectroscopic, and biological data are reported.

A potential naphthyl-thiazole-based organic dye and a ditopic chromogenic probe for CN- and Fe3+ with molecular logic functions

Dye sensitizers are entities designed primarily to serve the function of harvesting light photons in the functional wavelength, which is centered on charge transfer mechanisms. A metal-free dye sensitizer (J) based on the naphthyl-thiazole groups was synthesized via a one-step reaction mechanism and characterized using UV-vis, H-1 NMR and fluorescence spectroscopic methods. The applications of J were investigated based on its charge transfer mechanisms of photoinduced electron transfer (PET) and excited-state intermolecular proton transfer (ESIPT) mechanisms. Subsequently, J displayed several charge transfer-based properties complementary to dye sensitizers, chemosensing and molecular logic functions. The properties were investigated and studied primarily in acetonitrile (CH3CN), as a polar solvent of choice. The optical properties of J were investigated through solvatochromism, aided by theoretical recreation, while chemosensing properties were investigated, thereby in the process establishing that J is a ditopic probe which could selectively discriminate CN-, F- and AcO- as well as Fe3+ in CH3CN, among other ions. In addition, the reversibility and reproducibility studies substantiated that J exhibits molecular logic operation properties, based on complementary IMP/INH logic functions. Thus, J can be utilized as a colorimetric molecular switch modulated by CN-/Hg2+.

A simple, rapid, expedient and sustainable green strategy for the synthesis of benz-/naphthimidazoles

A versatile green chemical procedure for the highly selective construction of 2-aryl substituted benz-/naphthimidazoles starting from the reaction of aromatic 1,2-diamines with a series of substituted arylthioprolines with three to five drops of water under simple grinding at ambient temperature in good yields is described. The short reaction time, simplified experimental procedure, the absence of extraction and chromatographic purification steps in addition to the environment affability makes this green strategy highly attractive in view of green chemistry. The expected reaction to furnish the thiazole grafted benz-/naphthimidazole did not occur. Perhaps the arylthioprolines could be in zwitterionic form, which could react with 1,2-diamine giving dihyrobenzimidazole, which undergoes air oxidation to furnish the 2-aryl benzimidazole rather than the expected thiazole grafted imidazoles.
