Discovery of a Pyrimidothiazolodiazepinone as a Potent and Selective Focal Adhesion Kinase (FAK) Inhibitor

Focal adhesion kinase (FAK) is a tyrosine kinase with prominent roles in protein scaffolding, migration, angio-genesis, and anchorage-independent cell survival and is an attractive target for the development of cancer therapeutics. However, current FAK inhibitors display dual kinase inhibition and/or significant activity on several kinases. Although multi-targeted activity is at times therapeutically advantageous, such behavior can also lead to toxicity and confound chemical-biology studies. We report a novel series of small molecules based on a tricyclic pyrimidothiazolodiazepinone core that displays both high potency and selectivity for FAK. Structure-activity relationship (S AR) studies explored modifications to the thiazole, diazepinone, and aniline tail, which identified lead compound BJG-03-025. BJG-03-025 displays potent biochemical FAK inhibition (IC50 = 20 nM), excellent kinome selectivity, activity in 3D-culture breast and gastric cancer models, and favorable pharmacokinetic properties in mice. BJG-03-025 is a valuable chemical probe for evaluation of FAK-dependent biology.

Thiazolyl-pyrazoline derivatives: In vitro and in silico evaluation as potential acetylcholinesterase and carbonic anhydrase inhibitors

Alzheimer’s disease (AD) is a complex, predominant, and progressive form of dementia. The treatment of AD alters depending on the cognitive and behavioral symptoms. The utility of cholinergic replacement by acetylcholinesterase (AChE) inhibitors in AD treatment has been well-documented so far. Recent studies have also demonstrated that human carbonic anhydrases (hCAs) serve as important targets for AD treatment. In an attempt to identify potent AChE and hCA inhibitors, new thiazolyl-pyrazolines (3a-k) were designed based on the molecular hybridization of thiazole and pyrazoline scaffolds. A facile and versatile synthetic route consisting of three steps, namely Claisen-Schmidt reaction, the formation of the 2-pyrazoline ring system, and Hantzsch thiazole synthesis was used to prepare compounds 3a-k. The synthesized derivatives were experimentally validated for efficacy by in vitro and direct enzymatic assays. Furthermore, the compounds were subjected to in silico screening using Schrodinger Suite software to identify the binding affinities of potential compounds based on Glide XP scoring, MM-GBSA calculating, and validation. The results of in vitro and in silico studies revealed that compounds 3a, 3f, and 3d were the most promising derivatives in this series due to their significant effects on AChE, hCA I, and hCA II, respectively.

Incorporation of Poly(Itaconic Acid) with Quaternized Thiazole Groups on Gelatin-Based Films for Antimicrobial-Active Food Packaging

Poly(itaconic acid) (PIA) was synthesized via conventional radical polymerization. Then, functionalization of PIA was carried out by an esterification reaction with the heterocyclic groups of 1,3-thiazole and posterior quaternization by N-alkylation reaction with iodomethane. The modifications were confirmed by Fourier transform infrared (FTIR) and proton nuclear magnetic resonance (H-1-NMR), as well as zeta-potential measurements. Their antimicrobial activity was tested against different Gram-negative and Gram-positive bacteria. After characterization, the resulting polymers were incorporated into gelatin with oxidized starch and glycerol as film adjuvants, and dopamine as crosslinking agent, to develop antimicrobial-active films. The addition of quaternized polymers not only improved the mechanical properties of gelatin formulations, but also decreased the solution absorption capacity during the swelling process. However, the incorporation of synthesized polymers increased the deformation at break values and the water vapor permeability of films. The antioxidant capacity of films was confirmed by radical scavenging ability and, additionally, those films exhibited antimicrobial activity. Therefore, these films can be considered as good candidates for active packaging, ensuring a constant concentration of the active compound on the surface of the food, increasing products’ shelf-life and reducing the environmental impact generated by plastics of petrochemical origin.

The novel sensitive and selective chemosensors for determination of multiple analytes

Novel chemosensors that are azo dyes bearing coumarin with indole and thiophene recognition moieties were synthesized. Sensor properties of the dyes were investigated within multiple basic environments that include various pH ranges, anions, and organic amines. Recognition of the basic media by the chemosensors that have acidic NH and NH2 groups, occurs via the deprotonation process which was supported with reversibility study and H-1 NMR experiments. The Density Functional Theory calculations have employed to support the experimental results. Chemosensors 6a and 6b showed remarkable detection ability in a pH range of 7-11 and they have been also successfully utilized in the determination of CN- in semi-aqueous media.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

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.
