Herein, nickel-catalyzed sustainable strategy for the synthesis of N-substituted pyrroles using butene-1,4-diols and butyne-1,4-diols with a series of aryl-, alkyl-, and heteroarylamines is reported. The catalytic protocol is tolerant of free alcohol, halide, alkyl, alkoxy, oxygen heterocycles, activated benzyl, and the pyridine moiety and resulted in up to 90% yield. Initial mechanistic studies involving defined nickel catalyst, determination of rate, and order of reaction including deuterium-labeling experiments were performed for pyrrole synthesis.

The one-pot sulfonylation/aminoalkylation of styrene derivatives furnishing substituted I³-sulfonylamines was accomplished through a photoredox-catalyzed four-component reaction. Besides one molecule of water and the sodium counterion of the sulfinate, all atoms of the starting materials are transferred to the final product, rendering this process highly atom-efficient. The operationally simple protocol allows for the simultaneous formation of three new single bonds (C-S, C-N, and C-C) and therefore grants rapid access to structurally diverse products.

Toxoplasma gondii (T. gondii) is an apicomplexan parasite that can cause eye disease, brain disease, and death, especially in congenitally infected and immune-compromised people. Novel medicines effective against both active and latent forms of the parasite are greatly needed. The current study focused on the discovery of such medicines by exploring a family of potential inhibitors whose antiapicomplexan activity has not been previously reported. Initial screening efforts revealed that niclosamide, a drug approved for anthelmintic use, possessed promising activity in vitro against T. gondii. This observation inspired the evaluation of the activity of a series of salicylanilides and derivatives. Several inhibitors with activities in the nanomolar range with no appreciable in vitro toxicity to human cells were identified. An initial structure-activity relationship was explored. Four compounds were selected for evaluation in an in vivo model of infection, and two derivatives with potentially enhanced pharmacological parameters demonstrated the best activity profiles.

Development of new treatment strategies and chemotherapeutic agents is urgently needed to combat the growing multidrug resistant species of Candida. In this direction, a new series of Cu (II), Co (II), Ni (II) and Zn (II) heteroleptic complexes were synthesized, characterized and evaluated for antifungal activity. Based on spectral characterization and physical measurements, an octahedral geometry was assigned to [Co(L1)(L2)ClH2O] (C2), [Ni(L1)(L2)ClH2O] (C3), [Zn(L1)(L2)ClH2O] (C4) complexes, while a distorted octahedral geometry was assigned to [Cu(L1)(L2)ClH2O] (C1) complex. All the synthesized compounds were tested for antifungal activity against 11 Candida albicans isolates, including fluconazole (FLC)-resistant isolates, by determining minimum inhibitory concentrations (MIC) and minimum fungicidal concentrations (MFC), following CLSI guidelines. The mechanism of their antifungal activity was assessed by studying their effect on the plasma membrane using flow cytometry and quantifying the ergosterol contents. All the test compounds showed varying levels of antifungal activity. Both the ligands showed moderate antifungal activity with a median MIC value of 100 mug/mL with no fungicidal activity. Compound C3 was the most potent compound with median MIC and MFC values of 0.10 and 1.60 mug/mL, respectively. Flow cytometry analysis revealed that these compounds at MFC values disrupt the cell membrane, resulting in propidium iodide entering the cells. These compounds also reduced a considerable amount of ergosterol content after treating the cells with MIC and sub-MIC values. This study indicates that these compounds have high antifungal activity against C. albicans, and have the potential to be developed as novel antifungal drugs.

The cationic ruthenium hydride complex [(PCy3) 2(CO)(CH3CN)2RuH]+BF 4- was found to be a highly effective catalyst for the C-H bond activation reaction of arylamines and terminal alkynes. The regioselective catalytic synthesis of substituted quinoline and quinoxaline derivatives was achieved from the ortho-C-H bond activation reaction of arylamines and terminal alkynes by using the catalyst Ru3-(CO)12/HBF 4·OEt2. The normal isotope effect (k CH/kCD = 2.5) was observed for the reaction of C 6H5NH2 and C6D5NH 2 with propyne. A highly negative Hammett value (rho = -4.4) was obtained from the correlation of the relative rates from a series of meta-substituted anilines, m-XC6H4NH2, with sigmap in the presence of Ru3(CO)12/ HBF4·OEt2 (3 mol % Ru, 1:3 molar ratio). The deuterium labeling studies from the reactions of both indoline and acyclic arylamines with DC?CPh showed that the alkyne C-H bond activation step is reversible. The crossover experiment from the reaction of 1-(2-amino-1-phenyl)pyrrole with DC?CPh and HC?CC6H4-p-OMe led to preferential deuterium incorporation to the phenyl-substituted quinoline product. A mechanism involving rate-determining ortho-C-H bond activation and intramolecular C-N bond formation steps via an unsaturated cationic ruthenium acetylide complex has been proposed.

The crystal structure and FTIR spectrum of 3-formylchromone (0) have been analysed. A new organic ligands, 3-(anilinomethylene)-2-methoxychroman-4-one (1) and 3-(1?,4?-benzodioxan-6?-aminomethylene)-2-methoxychroman- 4-one (2) were synthesized. The products of reactions between 3-formylchromone and aniline and 6-amino-1,4,-benzodioxane were studied by elemental analysis, FTIR spectroscopy, thermal analysis and X-ray crystallography. It has been found that these reactions allow to obtain derivatives of 4-chromanones from 3-formylchromone by the mechanism of nucleophilic addition, accompanied by the opening of the pyrone ring. The experimental results indicate that compounds (1) and (2) are thermal stable up to 90 and 100 C, respectively. The FTIR spectra and X-ray analysis showed the present of methoxy-group in these compounds.

Abstract: A novel scaffold of N-substituted (3-(1-aminoethylidene)-2-oxochroman-4-yl)phosphonic acid diethyl ester derivatives was designed, synthesized and evaluated as acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) inhibitors against Alzheimer?s disease. Compounds 2a, 2b, 2d and 2q proved to be more potent than the standard drug galantamine and rivastigmine for AChE inhibitory activity with IC50 value between 0.50 and 3.94 muM. All the synthesized compounds proved to be only weak BuChE inhibitors. The compounds showed cytotoxicity in the same range as that of standard drugs against HEK-293 cells. Molecular docking studies suggested that compound 2q is acting as a dual binding site inhibitor by occupying the enzymatic catalytic active site, mid-gorge and peripheral anionic site. The coumarin moiety showed a pi?pi stacking interaction with Trp84 and hydrogen bonds with the P=O and C=O was found with Ser122 and Tyr121 at the catalytic active site. At the peripheral anionic site, the phenyl ring and quinoline ring were stacked against the Tyr 334 and Trp279 through pi?pi stacking interaction, respectively. The predicted ADME showed a good pharmacokinetic profile. DNA cleavage studies suggested that compounds 2a, 2b, 2d and 2q can be considered as non-toxic. Thus, compound 2q could be a promising lead structure for further development as anti-Alzheimer agents. Graphic abstract: [Figure not available: see fulltext.].
