Quinazoline clubbed thiazole and 1,3,4-oxadiazole heterocycles: synthesis, characterization, antibacterial evaluation, and molecular docking studies

In search of potent antibacterial agents, a series of novel quinazolines, bearing thiazole and 1,3,4-oxadiazole heterocycles 6a-j (3-(4-methyl-5-(4-((arylamino)methyl)-5-thioxo-4,5-dihydro-1,3,4-oxadiazol-2-yl)thiazol-2-yl)-2-phenylquinazolin-4(3H)-ones) were synthesized and the structures of the compounds were elucidated by standard spectroscopic techniques. In order to evaluate their antibacterial potential, the antibacterial assay of synthesized compounds 6a-j was performed against MTCC strains, wherein compounds 6d (3-(4-methyl-5-(4-(((4-nitrophenyl)amino)methyl)-5-thioxo-4,5-dihydro-1,3,4-oxadiazol-2-yl)thiazol-2-yl)-2-phenylquinazolin-4(3H)-one) (Escherichia coli, MIC = 100 mu g mL(-1)) and 6e (3-(5-(4-(((2-chlorophenyl)amino)methyl)-5-thioxo-4,5-dihydro-1,3,4-oxadiazol-2-yl)-4-methylthiazol-2-yl)-2-phenylquinazolin-4(3H)-one) (E. coli, MIC = 62.5 mu g mL(-1)) were most active against Gram-negative bacteria while compound 6f (3-(5-(4-(((4-chlorophenyl)amino)methyl)-5-thioxo-4,5-dihydro-1,3,4-oxadiazol-2-yl)-4-methylthiazol-2-yl)-2-phenylquinazolin-4(3H)-one) (Staphylococcus aureus, MIC = 50 mu g mL(-1)) was most active against Gram-positive bacteria. Furthermore, molecular docking simulation was performed to determine the probable binding mode and affinity of the synthesized compounds toward bacterial DNA gyrase.

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.

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.

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.

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.

An Efficient Precatalyst Approach for the Synthesis of Thiazole-Containing Conjugated Polymers via Cu-Catalyzed Direct Arylation Polymerization (Cu-DArP)

Over the past decade, direct arylation polymerization (DArP) has emerged as a facile and sustainable methodology for the synthesis of conjugated polymers. Recently, we developed Cu-catalyzed DArP (Cu-DArP) as a low-cost, Pd-free synthetic pathway, which enables conjugated polymers to be synthesized with high molecular weights and minimization of defects. However, the lack of study on the use of Cu-precatalysts in small-molecule direct arylation poses significant limitations for Cu-DArP to potentially overtake conventional Pd-catalyzed methodology, such as the low solubility and stability of the previously employed Cul. Therefore, in this report, we decide to explore the utility of a well-defined, easy-to-prepare, highly soluble, and stable precatalyst, Cu(phen)(PPh3)Br, as an alternative to the Cul, 1,10-phenanthroline catalytic system previously used for Cu-DArP. Herein, we report a drastic improvement of Cu-DArP methodology for the synthesis of 5,5′-bithiazole (5-BTz)-based conjugated polymers enabled by an efficient precatalyst approach, affording polymers with good M-n (up to 163 kDa) and excellent yields (up to 79%). H-1 NMR studies reveal the exclusion of homocoupling defects, which further verifies the excellent stability of Cu(phen)(PPh3)Br compared to CuI. Furthermore, we were able to decrease the catalyst loading from 15 mol % to only 5 mol % (M-n of 11.8 kDa, 64% yield), which is unprecedented when aryl bromides are employed for Cu-DArP. Significantly, 5-BTz was shown to be inactive under various of Pd-DArP conditions, which demonstrates the high compatibility of Cu-DArP as the only pathway for the C-H activation of the 5-BTz unit and a clear case demonstrating an advantage of Cu-DArP relative to Pd-DArP.

Design, synthesis and biological assessment of new selective COX-2 inhibitors including methyl sulfonyl moiety

Nonsteroidal anti-inflammatory drugs (NSAIDs) cause peptic lesions in the gastrointestinal mucosa by inhibiting the cyclooxygenase-1 (COX-1) enzyme. Selective COX-2 inhibition causes decreased side effects over current NSAIDs. Therefore, the studies about selective inhibition of COX-2 enzyme are very important for new drug development. The design, synthesis and biological activity evaluation of novel derivatives bearing thiazolylhydrazine-methyl sulfonyl moiety as selective COX-2 inhibitors were aimed in this paper. The structures of synthesized compounds were assigned using different spectroscopic techniques such as H-1 NMR, C-13 NMR and HRMS. In addition, the estimation of ADME parameters for all compounds was carried out using in silico process. The evaluation of in vitro COX-1/COX-2 enzyme inhibition was applied according to the fluorometric method. According to the enzyme inhibition results, synthesized compounds showed the selectivity against COX-2 enzyme inhibition as expected. Compounds 3a, 3e, 3f, 3g, 3i and 3j demonstrated significant COX-2 inhibition potencies. Among them, compound 3a was found to be the most effective derivative with an IC50 value of 0.140 +/- 0.006 mM. Moreover, it was seen that compound 3a displayed a more potent inhibition profile at least 12-fold than nimesulide (IC50 = 1.684 +/- 0.079 mu M), while it showed inhibitory activity at a similar rate of celecoxib (IC50 = 0.132 +/- 0.005 mu M). Molecular modelling studies aided in the understanding of the interaction modes between this compound and COX-2 enzyme. It was found that compound 3a had a significant binding property. In addition, the selectivity of obtained derivatives on COX-2 enzyme could be explained and discussed by molecular docking studies. (C) 2020 Elsevier Masson SAS. All rights reserved.
