Objective: To synthesize a series of phenanthrene-thiazolidinedione hybrids and explore their cytotoxic potential against human cancer cell lines of A-549 (lung cancer), HCT-116 and HT-29 (colon cancer), MDA MB-231 (triple-negative breast cancer), BT-474 (breast cancer) and (mouse melanoma) B16F10 cells. Methods: A new series of phenanthrene-thiazolidinedione hybrids was synthesized via Knoevenagel condensation of phenanthrene-9-carbaldehyde and N-alkylated thiazolidinediones. The cytotoxicity (IC50) of the synthesized compounds was determined by MTT assay. Apoptotic assays like (AO/EB) and DAPI staining, cell cycle analysis, JC-1 staining and Annexin V binding assay studies were performed for the most active compound (Z)- 3-(4-bromobenzyl)-5-((2,3,6,7-tetramethoxyphenanthren-9-yl)methylene)thiazolidine-2,4-dione (17b). Molecular docking, dynamics and evaluation of pharmacokinetic (ADME/T) properties were also carried out by using Schrodinger. Results and Discussion: From the series of tested compounds, 17b unveiled promising cytotoxic action with an IC50 value of 0.985 +/- 0.02 mu M on HCT-116 human colon cancer cells. The treatment of HCT-116 cells with 17b demonstrated distinctive apoptotic morphology like shrinkage of cells, horseshoe-shaped nuclei formation and chromatin condensation. The flow-cytometry analysis revealed the G(0)/G(1) phase cell cycle arrest in a dosedependent fashion. The AO/EB, DAPI, DCFDA, Annexin-V and JC-1 staining studies were performed in order to determine the effect of the compound on cell viability. Computational studies were performed by using Schrodinger to determine the stability of the ligand with the DNA. Conclusion: The current study provides an insight into developing a series of phenanthrene thiazolidinedione derivatives as potential DNA interactive agents which might aid in colon cancer therapy.

New acetamide (IV a-e) and 1,3-thiazolidinone derivatives (VII a-e) were designed, synthesized and assessed for their cytotoxic activity against MCF-7 and A549 cell lines along with their lead compounds (erlotinib and gefitinib). The newly designed compounds were prepared according to the adopted procedures in schemes 1 and 2 from their quinazolinone parents. 3D QSAR pharmacophore and docking molecular modeling protocols were conducted using Discovery Studio program, beside a full biological assay for these compounds. The cytotoxicity evaluation demonstrated that compounds IVb, IVc, VIIa, VIIb, VIId exhibited potent cytotoxic activities against both MCF-7 and A549 cell lines. Moreover, the molecular modeling studies corroborated to the affinity of the compounds towards EGFR. Consequently, these five compounds were then screened for their EGFR inhibition and evaluated as well for their toxicity to normal cells, which revealed that the acetamide derivative IVc and the thiazolidinone derivative VIIa were the most potent and least toxic. DNA flow cytometry analysis was conducted for compounds IVc and VIIa, which indicated that they both induced arrest at G2/M phase of the cell cycle.

Reactions in water as a safe and cheap solvent is a major goal of green chemistry. Actual synthesis of pyrido-dipyrimidine scaffold, named DNA-base hybrids, involves catalysis in hazardous solvents. Here we synthesised pyrido-dipyrimidines by one-pot heterocyclization of thiobarbituric acid, vanillic aldehydes and amines in water. Enamine and vanillidene are key intermediates of the Biginelli-like reaction mechanism. Our synthetic method displays several benefits such as the use of a green medium and various substrates, and yields up to 99%.

The oil and gas industry suffers from severe economic impact due to the corrosion of pipelines during the industrial oil-well acidizing process and because of the sweet corrosion of steel. One of the most common solutions to counter this issue is applying organic compounds as corrosion inhibitors. Conventionally used inhibitors are quite cumbersome to synthesize, are costly, and most are toxic. Therefore, there exists a need for research and development of novel, cost-effective, and eco-friendly corrosion inhibitors showing efficient inhibition performance. The present work describes the basics of corrosion, its economic impact, and the main strategies to counter this issue. Fundamentals of sweet corrosion, the mechanism involved, the influence of various governing factors, and the limitations of the existing inhibitor chemistries are explained. Some of the prominent classes of the environmentally benign sweet corrosion inhibitors such as the biopolymers, heterocyclic molecules, and pharmaceutical products are also outlined. The focus is on the recent research work in this area, and some of the prospective research aspects are envisaged. (C) 2020 Published by Elsevier B.V.

A new efficient approach to the synthesis of 6-alkenyl substituted pyridoxine derivatives has been developed. A series of 31 novel alkenyl pyridoxine derivatives, stilbene-based bioisosteric analogs of estradiol, were synthesized. In vitro cytotoxicity of the obtained compounds against MCF-7 (ER+) breast cancer tumor cells was studied using the MTT assay. The most active compounds with IC50, MCF-7 < 10 mu M were also tested for cytotoxicity in vitro against MDA-MB-231 (ER-) breast adenocarcinoma cells and conditionally normal human skin fibroblasts (HSF). The patterns of structure-antitumor activity relationships of the obtained compounds were analyzed. The most active compounds were found to contain a six-membered ketal ring, a methyl group in position 5, a 3,4-dimethoxystyryl fragment in positions 2 or 6 of the pyridoxine ring, and a trans-configuration of the double bond. Using the most active compound 5a as a representative cytotoxic agent, we have demonstrated that it has high specificity and antiproliferative activity against MCF-7 (ER+) tumor cells (IC50 < 5 mu M), and a higher therapeutic index compared to the reference compound raloxifene (48 versus 5.8). Compound 5a decreased the mitochondrial membrane potential and increased the level of reactive oxygen species in MCF-7 cells, but not MDA-MB-231 cells. Compound 5a did not affect the distribution of cell cycle phases and induced apoptosis in MCF-7 cells, but not MDA-MB-231. Unlike compound 5a, raloxifene decreased mitochondrial potential, increased the ROS level, and induced apoptosis in both MCF-7 and MDA-MB-231 cells, which indicated a lack of selectivity for cells with estrogen receptor expression. It was also shown that compound 5a reduced the level of ER alpha expression in cells to a lesser extent than raloxifene and, unlike the latter, did not activate the PI3K/Akt signaling pathway.

Two magnetic nano catalysts of nickel and copper, Fe3O4@SiO2@DOP-BenPyr-M(II), (M=Ni and Cu) have been synthesized. These catalysts were applied as recoverable, efficient and new heterogeneous catalysts for the high yielding and room temperature one-pot procedure of selective oxidation of sulfides to sulfoxides and oxidative coupling of thiols to disulfides. In addition, the catalytic activity of Fe3O4@SiO2@DOP-BenPyr-Ni(II) was investigated as heterogeneous nanocatalyst for synthesis of 2,3-dihydroquinazolin-4(1H)-ones, 5-substituted 1H-tetrazoles and polyhydroquinolines. The synthesized catalysts were characterized by FT-IR, TGA, XRD, VSM, EDX, ICP and SEM techniques. These catalysts were recovered by an external magnet and reused several times without significant loss of catalytic efficiency. [GRAPHICS] .

A decarboxylative protocol has been developed toward a range of carbocycles. The key success is based on the use of a batch of newly designed cyclic carbonates as substrates that can provide carbon-carbon zwitterion intermediate under palladium catalysis. The kinetics of the reactions are controllable toward either strained seven- or thermodynamically more favored five-membered carbocycles. The release of this chemistry will shed light on the synthesis of complex and valuable cyclic structures.

A unique enantioselective nickel-catalyzed vinylation of 2-azaallyl anions is advanced for the first time. This method affords diverse vinyl aryl methyl amines with high enantioselectivities, which are frequently occurring scaffolds in natural products and medications. This C-H functionalization method can also be extended to the synthesis of enantioenriched 1,3-diamine derivatives by employing suitably elaborated vinyl bromides. Key to the success of this process is the identification of a Ni/chiraphos catalyst system and a less reducing 2-azaallyl anion, all of which favor an anionic vinylation route over a background radical reaction. A telescoped gram scale synthesis and a product derivatization study confirmed the scalability and synthetic potential of this method.

The synthesis of nitrogen- and oxygen-containing heterocycles has found many applications in the preparation of biomedical intermediates, yet actual synthetic procedures display limitations such as high-loading catalysts, harsh reaction conditions and tedious preparation of heterogeneous catalysts. Alternatively, photocatalysis allows to access functional products with minimum synthetic procedures and waste generation. Here, we present an efficient, simple, green protocol for the synthesis of N- and O-containing six-membered-ring compounds under mild conditions under visible blue light. Various aldehydes and 1,3-diketones can be reacted to afford eight series of corresponding 1,4-dihydropyridines and 4H-benzo[b]pyrans. This protocol has some merits such as the use of abundant and sustainable aqueous ethanol as solvent, short reaction time (within 60 min), no need of catalyst and broad functional group tolerance to afford 81 different series of target molecules in 75-96% yield under mild conditions.
