Herin we report the design, synthesis, full characterization and biological investigation of new 15-LOX/COX dual inhibitors based on 1,3-thiazolidin-4-one (15-lipoxygenase pharmacophore) and 1,3,4-thiadiazole (COX pharmacophore) scaffolds. This series of molecular modifications is an extension of a previously reported series to further explore the structural activity relationship. Compounds 3a, 4e, 4n, 4q, 7 and 8 capable of inhibiting 15-LOX at (2.74, 4.2, 3.41, 10.21, 3.71 and 3.36 mu M, respectively) and COX-2 at (0.32, 0.28, 0.28, 0.1, 0.28 and 0.27 mu M, respectively). The results revealed that binding to 15-LOX and COX is sensitive to the bulkiness of the substituents at the 5 positions. 15-LOX bind better with small substituents, while COXs bind better with bulky substituents. Compounds 3a, 4r and 4q showed comparable in vivo anti-inflammatory activity to the reference drug (celecoxib). The ulcer liability test showed no sign of ulceration which ensures the safe gastric profile. Docking study was performed to explore the possible mode of interaction of the new compounds with the active site of human 15-LOX and COX-2. This study discloses some structural features for binding to 15-LOX and COX, thus pave the way to design anti-inflammatory agents with balanced dual inhibition of these enzymes.

Infectious diseases caused by fungi and mycobacteria pose an important problem for humankind. Similarly, cancer is one of the leading causes of death globally. Therefore, there is an urgent need for the development of novel agents to combat the deadly problems of cancer, tuberculosis, and also fungal infections. Hence, in the present study, we designed, synthesized, and characterized 30 compounds including 15 chalcones (2-16) and 15 dihydropyrazoles (17-31) containing dichlorophenyl moiety and also screened these compounds for their antifungal, antitubercular, and antiproliferative activities. Among these compounds, the dihydropyrazoles showed excellent antifungal and antitubercular activities whereas the chalcones exhibited promising antiproliferative activity. Among the dihydropyrazoles, compound31containing 2-thienyl moiety showed promising antifungal activity (MIC 5.35 mu M), whereas compounds22and24containing 2,4-difluorophenyl and 4-trifluoromethyl scaffolds revealed significant antitubercular activity with the MICs of 3.96 and 3.67 mu M, respectively. Compound16containing 2-thienyl moiety in the chalcone series showed the highest anti-proliferative activity with an IC(50)value of 17 +/- 1 mu M. The most active compounds identified through this study could be considered as starting points in the development of drugs with potential antifungal, antitubercular, and antiproliferative activities.

Self-assembly of diverse Cd(II) metal salts, four organic dicarboxylic acids, and two flexible bis(pyridyl) ligands leads to the formation of thirteen complexes, namely, [Cd(L1)(C4H4O4)] n (1), [Cd(L2)(C4H4O4)(0.5)](n) center dot nOH center dot 8nH(2)O (2), [Cd(L1)(C4H2O4)](n) (3), [Cd(L1)(C4H2O4)](n) (4), [Cd-2(L-2)(C4H2O4)(2)(H2O)(2)](n) center dot nH(2)O (5), [Cd-2(L1)(m-BDC)(2)(H2O)(2)] n (6), [Cd-2(L-2)(m-BDC)(2)(H2O)(2)] n (7), [Cd-3(L1)(2)(p-BDC) 3(H2O) 4] n center dot 2nH(2)O (8), [Cd(L2)(p-BDC)(0.5)Cl] n (9), [Cd(L2)(p-BDC) 0.5(H2O)] n center dot n(ClO4) center dot nH(2)O (10), [Cd-3(L2)(2)(p-BDC)(SO4)(2)(H2O)(6)]n center dot 4nH2O (11), [Cd(L2)(p-BDC)](n) center dot nH(2)O (12) and [Cd(L2)(p-BDC)](n) center dot nMeOH (13) (L1 = N, N’-bis(pyridin4- ylmethyl) propane-1,2-diamine, L2 = N, N’-bis(pyridin-3-ylmethyl) propane-1,2-diamine, m-BDC2-= m-benzene dicarboxylate dianion, p-BDC2-= p-benzene dicarboxylate dianion), which have been characterized by elemental analysis, IR, TG, PL, and powder and single-crystal X-ray diffraction. The influence of different Cd(II) salts on the structure variations and properties has also been investigated. Complexes 1 and 3 present a (4,4) layer motif accomplished by the interconnection of adjacent Cd(II) cations through L1 molecules and trans-conformational succinates or fumarates. In contrast, the cis-conformational succinates in complex 2 only afford the formation of a chain structure. The L1 and L2 molecules in complexes 4 and 5 adopt the same coordination and join adjacent Cd(II) cations together with fumarates, giving rise to different 3D networks with vma and irl topologies. The same coordination mode of L1 and L2 in complexes 6-8 joins adjacent Cd(II) cations together with aromatic dicarboxylates, leading to different (63)(65 center dot 8), 2-periodic (6 center dot 3) and (4 center dot 4) layer motifs. The L2 molecules in complexes 9-13 present different coordination modes and join adjacent Cd(II) cations together with p-BDC2-dianions to form diverse (6 center dot 3) layer motifs, and different 3D networks with cds and eca topologies. Therefore, the diverse coordination modes of the bis(pyridyl) ligand and the feature of different organic dicarboxylate anions can effectively influence the topological structures of these complexes. Luminescence investigation reveals that the emission maximum of these complexes varies from 403 to 433 nm in the solid state at room temperature.

Tyrosyl-DNA phosphodiesterase 1 (Tdp1) is a promising therapeutic target in cancer therapy. Combination chemotherapy using Tdp1 inhibitors as a component can potentially improve therapeutic response to many chemotherapeutic regimes. A new set of usnic acid derivatives with hydrazonothiazole pharmacophore moieties were synthesized and evaluated as Tdp1 inhibitors. Most of these compounds were found to be potent inhibitors with IC50 values in the low nanomolar range. The activity of the compounds was verified by binding experiments and supported by molecular modeling. The ability of the most effective inhibitors, used at non-toxic concentrations, to sensitize tumors to the anticancer drug topotecan was also demonstrated. The order of administration of the inhibitor and topotecan on their synergistic effect was studied, suggesting that prior or simultaneous introduction of the inhibitor with topotecan is the most effective.

The synthesis of alpha,beta-unsaturated ketones from aerobic oxidation of allylic alcohols and biobased olefins serves as an important topic in green and sustainable chemistry. In this work, we report the utilization of a sacrificial template ZIF-8 for preparation of mesoporous Co-0.05/N-C material with an ultralow cobalt loading of 0.05 wt %, in which the excellent catalytic performance in aerobic oxidation of alpha-pinene and cinnamyl alcohol was achieved with an 85% yield of verbenone and a yield of cinnamaldehyde, respectively. The results of control experiments and several characterization investigations further illustrate that the sacrificial template ZIF-8 plays a key role to disperse well metallic cobalt in the Co-0.05/N-C-800 catalyst and an appropriate cobalt content of 0.05 wt % is beneficial for benign and efficient aerobic oxidation of various allylic alcohols and biobased olefins. In addition, the Co0.05/N-C-800 catalyst also exhibited good stability and reusability for recovering and reusing at least six times without obvious decrease in catalytic activity. The presented efficient nanocatalyst thus triggers facile synthesis of a series of alpha,beta-unsaturated aldehydes/ketones in high yields.

New sulfonamide-hydrazone derivatives (3a-3n) were synthesized to evaluate their inhibitory effects on purified human carbonic anhydrase (hCA) I and II. The inhibition profiles of the synthesized compounds on hCA I-II isoenzyme were investigated by comparing their IC50 and K-i values. Acetazolamide (5-acetamido-1,3,4-thia-diazole-2-sulfonamide, AZA) has also been used as a standard inhibitor. The compound 3e demonstrated the best hCA I inhibitory effect with a K-i value of 0.1676 +/- 0.017 mu M. Besides, the compound 3m showed the best hCA II inhibitory effect with a K-i value of 0.2880 +/- 0.080 mu M. Cytotoxicity of the compounds 3e and 3m toward NIH/3T3 mouse embryonic fibroblast cell line was observed and the compounds were found to be non-cytotoxic. Molecular docking studies were performed to investigate the interaction types between active compounds and hCA enzymes. Pharmacokinetic profiles of compounds were assessed by theoretical ADME predictions. As a result of this study a novel and potent class of CA inhibitors were identified with a good activity potential.

Novel task dicationic ionic liquids (Ts-DilLs) 6-29 were designed and synthesized, under both conventional and microwave conditions; through molecular hybridization of the appropriate bispyridines having a hydrazone linkage as spacer with some alkyl functionalized esters forming the counter cations. Beside the synthesized halogenated DilLs 6-11, fluorinated metal anions were introduced via metathesis reaction in order to create new dipyridinium ionic liquid-hydrazone hybrids 12-29. All newly synthesized DilLs were fully characterized using different spectroscopic tools such as H-1, C-13, F-19, P-31, B-11 NMR and Mass experiment. The DNA binding, anticancer and docking studies of the synthesized ionic liquids were also carried out. The DNA binding constants ranged from 4.5 x 10(4) to 7.2 x 10(4) M-1, indicating good DNA binding tendencies. The most active ionic liquids were 28 and 29 with 99.99 and 99.86% anticancer activities, respectively. The docking studies indicated DNA binding in the outer grooves of DNA. The reported ionic liquids may be used as future anticancer drugs. (C) 2020 Elsevier B.V. All rights reserved.

Here we present a comprehensive study on the [3+2]-cycloaddition of thiocarbonyl ylides with a wide variety of alkenes and alkynes. The obtained dihydro- and tetrahydrothiophene products serve as exceptionally versatile intermediates providing access to thiophenes, dienes, dendralenes, and vic-quarternary carbon centers. The use of high-pressure conditions enables thermally unstable, sterically encumbered or moderately reactive substrates to undergo the cycloaddition under mild conditions, thereby increasing the yield by up to 58%. In addition, we showcase its utility by the formal syntheses of the pharmaceuticals NGB 4420 and tenilapine.
