The Pot, Atom, and Step Economy (PASE) approach is based on the Pot economy principle and unites it with the Atom and Step Economy strategies; it ensures high efficiency, simplicity and low waste formation. The PASE approach is widely used in multicomponent chemistry. This approach was adopted for the synthesis of previously unknown hydroxyquinolinone substituted chromeno[2,3-b]pyridines via reaction of salicylaldehydes, malononitrile dimer and hydroxyquinolinone. It was shown that an ethanol-pyridine combination is more beneficial than other inorganic or organic catalysts. Quantum chemical studies showed that chromeno[2,3-b]pyridines has potential for corrosion inhibition. Real time H-1 NMR monitoring was used for the investigation of reaction mechanism and 2-((2H-chromen-3-yl)methylene)malononitrile was defined as a key intermediate in the reaction.

The given report introduces a simple and user-friendly in situ method for the production of catalytically active cobalt particles. The approach circumvents the use of air- and moisture-sensitive reductants as well as the application of anhydrous Co-precursor salts. Accordingly, the described catalytic system is readily assembled under open-flask conditions by simply combining the components in the reaction vessel. Therefore, the arduous charging procedure of the reaction autoclave in a glovebox under an inert gas atmosphere is no longer necessary. In fact, the catalytically active material is obtained upon treatment of readily available Co(OAc)(2)center dot 4 H2O with benign commercial Zn powder. The catalytic performance of the resultant material was tested in the heterogeneous hydrogenation of nitriles to the corresponding primary amines. Both activity and selectivity of the cobalt catalyst are significantly enhanced if a triflate-based Lewis acid and ammonia is added to the reaction mixture.

A series of novel camphor-based pyrimidine derivatives (3a-3x) have been synthesized; their structures were determined by using conventional methods and compound 3f was further confirmed through single crystal XRD analysis. The cytotoxic activity of the target compounds against a panel of human normal (GES-1) and cancer cell lines (MDA-MB-231, RPMI-8226, A549) was evaluated by MTS assay. Here we found that compound 3f exhibited the strongest anti-tumor activity, comparable to that of etoposide, and had much lower cytotoxicity to normal GES-1 cells (IC50 > 50 mu M) than the reference drug (IC50 = 8.89 mu M). Subsequent mechanism studies in MDA-MB-231 cells revealed that compound 3f caused G0/G1 phase arrest and apoptosis in a dose dependent manner. Moreover, the loss of mitochondrial membrane potential and enhancement of cellular ROS levels were also observed upon 3f treatment, which indicated that 3f exerted cytotoxic activity by a ROS-mediated mitochondrial apoptosis pathway. This result was confirmed by a significant increase in the expression of pro-apoptotic proteins Bax, cytochrome C and caspase-3, and downregulation of anti-apoptosis protein Bcl-2. Overall, 3f can be adopted for further investigation in the development of antitumor agents based on natural products.

A modest, competent and green synthetic procedure for novel coumarinyl-1,3,4-oxadiazolyl-2mercaptobenzoxazoles 8i-t has been reported. Analysis of the docked (PDB ID: 5IKR; A-Chain) poses of the compounds illustrated that they adopt identical conformations to the extremely selective COX-2 inhibitor. The biological outcomes as well as computational study suggested that the compounds originated to have elevated resemblance towards COX-2 enzyme than COX-1. The compounds 8i, 8l, 8q, 8r, 8s and 8t emerged as most potent and selective COX-2 inhibitors in contrast with Mefenamic acid. The selectivity index of 8l, 8n and 8r was respectively found to be 33.95, 20.25 and 24.98 which manifested their high selectivity against COX-2. Interestingly, the compounds which were active as COX-2 inhibitors were also active as antioxidant agents.

The aromatic C-H bond etherification with alcohols is one of the most atom-efficient ways to construct aryl ethers. However, it often requires a large excess of alcohols as etherification reagents, which limits the substrate scope (especially for the valuable alcohols). Herein, an alternative mechanochemical C-H bond etherification of oximes with diverse primary and secondary alcohols was developed for the first time. Given the solvent-less condition of ball milling technique, the amount of alcohols used in this chemistry has been significantly reduced (1.5-3.0 equiv to the substrates), thus enabling the incorporation of a wide range of alcohols in the C-H bond etherification for the first time. The present mechanochemical protocol enhances the application prospect of the cross dehydrogenative C-H etherification strategy in the late-stage synthesis of complex aromatic ethers.

A surfactant based oxodiperoxo molybdenum complex, which could activate molecular oxygen, has been employed as a catalyst for controlled oxidation of benzylic alcohols to corresponding carbonyls. The oxidation reactions were carried out under aqueous environment, however, in the absence of any extraneous base or co-catalyst. Sensitive/oxidizable functional groups like cyano, sulfide, hydroxyl, aryl-hydroxyl, alkene (internal/terminal), alkyne (internal/terminal), and acetal were tolerated during the transformations. Such selectivity is attributed to the mild nature of the catalyst. The methodology could also be scaled-up for multi-gram synthesis and the protocol is likely to find practical use since it requires an inexpensive recyclable-catalyst and easily available oxidant (under green conditions). A plausible mechanism is proposed with the help of preliminary computational study. (C) 2019 Elsevier Inc. All rights reserved.

In recent days, synthesis of anticancer molecules having both low adverse effects and specific protein targeting are seldom. Synthesis of anticancer molecules having both low adverse effects and specific protein targeting is challenging. The main objective of our study was to develop molecules that can target activated protein kinase P38 alpha and activin receptor (ALK2) kinase for treating carcinoma. P38 alpha is involved in cell differentiation, apoptosis, and autophagy.Activin receptor (ALK2) kinase is responsible for mutations of cancerous cells. The synthesis of N-Methyl – 2, 3 -Disubstituted Quinazolin-4-Ones was carried out by refluxing of 1-methyl-2-(pyridinyl)-1,2-dihydro-4H-3,1-benzoxazin-4-one with 4-substituted phenyl-1,3-thiazol-2-amines. The molecular docking of 1-methyl-3-(4-substituted phenyl-1,3-thiazol-2-yl)2-(pyridin-3-yl)-2,3-dihydroquinazolin-4(1H)-one (5Da1-5Dk11) and 1-methyl-3-(4-substituted phenyl- 1,3-thiazol-2-yl)-2-(pyridin-4-yl)-2,3dihydroquinazolin-4(1H)-one (5Ea1-5Ek11) derivatives were carried out using Schrodinger Glide (version 2020_1) software. Twenty-two quinazoline-4-one derivatives were docked into selective P38 alpha and ACVR1 (ALK2) kinase with PDB code 3GC7, 6GI6. Based on the docking score, comparison between quinazolin-4-one derivatives, co-crystallized Ligands interaction was evaluated using 5-Fluorouracil as standard. Best activity was found in compounds 5Df6, 5Dd4, 5Ed4 and 5Ef6 with ACVR1 (ALK2) kinase with score of -8.223, -7.936, -8.123, 7.907 and 5Df6, 5Dh8, 5Eb2 and 5Ee5 with P38alpha with score of -7.19, -7.027, -6.698, -6.789 Kcal/mol against enzymes responsible for treatment for cancer compare with reference drug score -5.765 and -6.195. This study will help in the design and development of a drug that gives room for the synthesis of a new selective ACVR1 (ALK2) kinase and P38alpha enzyme inhibitor with predetermined affinity and activity of the compound.

A new recyclable nanocatalyst consisting of heteropoly acid grafted on ionic liquid modified LaMnO3 nanoparticles was synthesized and accomplished as an efficient catalyst in condensation reaction for the preparation of tetrahydrobenzo[b]pyrans under solvent-free conditions. In addition, it was clarified that supported heteropoly acid (HPA) is the active site for the catalytic reaction, whereas the LaMnO3, ionic liquid functionalized lanthanum manganite nanoparticles are inactive. Different physicochemical methods such as Fourier transform infrared (FT-IR), X-ray powder diffraction (XRD), and field emission scanning electron microscopy (FESEM) were used to characterize the hybrid nanomaterial. The nanocatalyst reusability was affirmed by the use of five consecutive runs. Compared with the various previously reported catalyst, the new synthesized catalyst was found to be the most efficient with regard to reaction time, yield and ease of catalyst separation.

We have developed a supramolecular (close form) [2]pseudorotaxane polymer containing the green-emissive (lambda(em) = 523 nm) BODIPY-based pillar[5]arene host and the non-emissive spiropyran (SP)-based cyano guest (close form), which can be converted to a red-emissive (lambda(em) = 630 nm) merocyanine (MC)-based guest (open form) upon UV exposure as well as turned into a bi-fluorophoric host-guest polymer with ratiometric PL emission of Forster resonance energy transfer (FRET) behavior in THF/water solution (60% H2O, v/v). The equal host-guest molar ratio and the formation of the [2]pseudorotaxane polymer can be further verified using H-1 NMR titration, Job’s plot analysis, DOSY and ITC experiments. Hence, the bi-fluorophoric host-guest (with the MC open form) polymer possessed the highest red-emission of the MC acceptor, which was also confirmed using TRPL measurements to possess the shortest lifetime of 0.37 ns and the best FRET efficiency of 83.5%. Since the MC unit could react with CN- to induce a non-emissive quenching process, the mono-fluorophoric guest would show turn-off PL behavior and detect cyanide ions with a corresponding limit of detection (LOD) value of 0.94 mu M. In comparison, the optimal LOD value of 0.48 mu M toward CN- anion could be achieved by our bi-fluorophoric host-guest polymer via the FRET-OFF process. Therefore, cyanide detection and cell viability tests using the open form of the [2]pseudorotaxane polymer suggest useful bio-imaging applications in living cells.
