Bumbăcilă B, Putz MV. Neurotoxicity of Pesticides: The Roadmap for the Cubic Mode of Action. Curr Med Chem 2020; 27:54-77. [DOI: 10.2174/0929867326666190704142354] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2018] [Revised: 05/08/2019] [Accepted: 06/20/2019] [Indexed: 01/15/2023]
Abstract
Pesticides are used today on a planetary-wide scale. The rising need for substances with this
biological activity due to an increasing consumption of agricultural and animal products and to the
development of urban areas makes the chemical industry to constantly investigate new molecules or to
improve the physicochemical characteristics, increase the biological activities and improve the toxicity
profiles of the already known ones. Molecular databases are increasingly accessible for in vitro and in
vivo bioavailability studies. In this context, structure-activity studies, by their in silico - in cerebro
methods, are used to precede in vitro and in vivo studies in plants and experimental animals because
they can indicate trends by statistical methods or biological activity models expressed as mathematical
equations or graphical correlations, so a direction of study can be developed or another can be abandoned,
saving financial resources, time and laboratory animals. Following this line of research the present paper
reviews the Structure-Activity Relationship (SAR) studies and proposes a correlation between a topological
connectivity index and the biological activity or toxicity made as a result of a study performed on 11 molecules
of organophosphate compounds, randomly chosen, with a basic structure including a Phosphorus atom
double bounded to an Oxygen atom or to a Sulfur one and having three other simple covalent bonds with two
alkoxy (-methoxy or -ethoxy) groups and to another functional group different from the alkoxy groups. The
molecules were packed on a cubic structure consisting of three adjacent cubes, respecting a principle of topological
efficiency, that of occupying a minimal space in that cubic structure, a method that was called the Clef
Method. The central topological index selected for correlation was the Wiener index, since it was possible
this way to discuss different adjacencies between the nodes in the graphs corresponding to the organophosphate
compounds molecules packed on the cubic structure; accordingly, "three dimensional" variants of these
connectivity indices could be considered and further used for studying the qualitative-quantitative relationships
for the specific molecule-enzyme interaction complexes, including correlation between the Wiener
weights (nodal specific contributions to the total Wiener index of the molecular graph) and the biochemical
reactivity of some of the atoms. Finally, when passing from SAR to Q(uantitative)-SAR studies, especially by
the present advanced method of the cubic molecule (Clef Method) and its good assessment of the
(neuro)toxicity of the studied molecules and of their inhibitory effect on the target enzyme - acetylcholinesterase,
it can be seen that a predictability of the toxicity and activity of different analogue compounds can
be ensured, facilitating the in vivo experiments or improving the usage of pesticides.

Synthesis of a New Series of Nitrogen/Sulfur Heterocycles by Linking Four Rings: Indole; 1,2,4-Triazole; Pyridazine; and Quinoxaline. Molecules 2020; 25:molecules25030450. [PMID: 31973234 PMCID: PMC7037119 DOI: 10.3390/molecules25030450] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2019] [Revised: 01/14/2020] [Accepted: 01/17/2020] [Indexed: 02/07/2023] Open
Abstract
A new series of nitrogen and sulfur heterocyclic systems were efficiently synthesized by linking the following four rings: indole; 1,2,4-triazole; pyridazine; and quinoxaline hybrids. The strength of the acid that catalyzes the condensation of 4-amino-5-(1H-indol-2-yl)-2,4-dihydro-3H-1,2,4-triazole-3-thione 1 with aromatic aldehydes controlled the final product. Reflux in glacial acetic acid yielded Schiff bases 2–6, whereas concentrated HCl in ethanol resulted in a cyclization product at C-3 of the indole ring to create indolo-triazolo-pyridazinethiones 7–16. This fascinating cyclization approach was applicable with a wide range of aromatic aldehydes to create the target cyclized compounds in excellent yield. Additionally, the coupling of the new indolo-triazolo-pyridazinethiones 7–13 with 2,3-bis(bromomethyl)quinoxaline, as a linker in acetone and K2CO3, yielded 2,3-bis((5,6-dihydro-14H-indolo[2,3-d]-6-aryl-[1,2,4-triazolo][4,3-b]pyridazin-3 ylsulfanyl)methyl)quinoxalines 19–25 in a high yield. The formation of this new class of heterocyclic compounds in high yields warrants their use for further research. The new compounds were characterized using nuclear magnetic resonance (NMR) and mass spectral analysis. Compound 6 was further confirmed by the single crystal X-ray diffraction technique.

Studies on the constituents of Helleborus purpurascens: use of derivatives from calix[6]arene, homooxacalix[3]arene and homoazacalix[3]arene as extractant agents for amino acids from the aqueous extract. Amino Acids 2019; 52:55-72. [PMID: 31853707 DOI: 10.1007/s00726-019-02809-z] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2019] [Accepted: 11/27/2019] [Indexed: 10/25/2022]
Abstract
The task of this work was to investigate the extraction capacity of various calixarenes for free and esterified amino acids from aqueous acid phases. Furthermore, this method was applied to aqueous extracts of Helleborus purpurascens. Generally, it is known that calixarenes can be used as extractants for ammonium compounds due to π-cation and lone pair cation interactions. As first, tert-Butyl-calix[6]arene and derivatives thereof were used. They had already proven their worth in previous investigations. In addition, tert-Butyl-hexahomooxa-calix[3]arene was used also, which can also enter into lone pair cation interactions. In addition to these well-known calixarenes, new calixarenes were produced and tested. Based on the tert-Butyl-hexahomooxa-calix[3]arene, a phosphor(III)bridged derivative was prepared, combining the three aromatic hydroxyl groups to a phosphite. As a seldom-described class of calixarenes, tert-Butyl-hexahomoaza-calix[3]arene derivatives were used. The nitrogen analogues of tert-Butyl-hexahomooxa-calix[3]arene could be produced as N-benzyl derivatives. The structure of the esterified carboxymethylated derivative of N,N',N″-Tribenzyl-tert-Butyl-hexahomoaza-calix[3]arene could be verified by X-ray structure analysis. It crystallized as a partial cone. The extraction capacity of the described calixarenes was investigated for amino acids from aqueous acidic solutions into an organic phase. For the testing were chosen asparagine, aspartic acid, tyrosine, tryptophane, phenylalanine and pipecolinic acid and their methyl esters. The amino acids and their methyl esters were dissolved in water at different pH values. The calixarenes were dissolved in dichloromethane (DCM) or chloroform. After this preparation, the aqueous acidic amino acid solutions were mixed with the solutions and shaken intensively. In addition, blank values were determined by extracting the aqueous stock solutions of the amino acids and their methyl esters with pure solvents. To determine the extraction rate, the phases were separated and each analysed using GC-FID, partially GC-MS(EI). The evaluation is performed in two ways. On the one hand the depletion in the aqueous phase and on the other hand the content in the organic phase was determined.

Abstract
Cisplatin and other platinum-based drugs are well-known valid anticancer drugs. However, during chemotherapy, the presence of numerous side effects and the onset of frequent phenomena of resistance has pushed many research groups to devise new metal-based compounds holding improved anticancer properties and fewer undesired effects. Amongst the variety of synthesized compounds, significant antiproliferative effects have been obtained by employing organometallic compounds, particularly those based on silver and gold. With this in mind, we synthesized four compounds, two silver complexes and two gold complexes, with good inhibitory effects on the in vitro proliferation of breast and ovarian cancer-cell models. The antitumor activity of the most active compound, that is, AuL4, was found to be ninefold higher than that of cisplatin, and this compound induced dramatic morphological changes in HeLa cells. AuL4 induced PARP-1 cleavage, caspases 3/7 and 9 activation, mitochondria disruption, cytochrome c release in cancer-cell cytoplasm, and the intracellular production of reactive oxygen species. Thus, AuL4 treatment caused cancer-cell death by the intrinsic apoptotic pathway, whereas no cytotoxic effects were recorded upon treating non-tumor cell lines. The reported outcomes may be an important contribution to the expanding knowledge of medicinal bio-organometallic chemistry and enlarge the available anticancer toolbox, offering improved features, such as higher activity and/or selectivity, and opening the way to new discoveries and applications.
