Jézéquel G, Cardoso LNDF, Olivon F, Dennemont I, Apel C, Litaudon M, Roussi F, Pomel S, Desrat S. Synthesis and Anti-Leishmanial Properties of Quinolones Derived from Zanthosimuline. Molecules 2022; 27:7892. [PMID: 36431992 PMCID: PMC9693141 DOI: 10.3390/molecules27227892] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Revised: 10/27/2022] [Accepted: 11/04/2022] [Indexed: 11/18/2022] Open
Abstract
Quinoline derivatives and especially quinolones are considered as privileged structures in medicinal chemistry and are often associated with various biological properties. We recently isolated a series of original monoterpenyl quinolones from the bark of Codiaeum peltatum. As this extract was found to have a significant inhibitory activity against a Leishmania species, we decided to study the anti-leishmanial potential of this type of compound. Leishmaniasis is a serious health problem affecting more than 12 million people in the world. Available drugs cause harmful side effects and resistance for some of them. With the aim of finding anti-leishmanial compounds, we developed a synthetic strategy to access natural quinolones and analogues derived from zanthosimuline. We showed the versatility of this natural compound toward cyclization conditions, leading to various polycyclic quinolone-derived structures. The natural and synthetic compounds were evaluated against amastigote forms of Leishmania infantum. The results obtained confirmed the interest of this family of natural compounds but also revealed promising activities for some intermediates deriving from zanthosimuline. Following the same synthetic strategy, we then prepared 14 new analogues. In this work, we identified two promising molecules with good activities against intramacrophage L. infantum amastigotes without any cytotoxicity. We also showed that slight changes in amide functional groups affect drastically their anti-parasitic activity.

Abstract
Specific S477N, N501Y, K417N, K417T, E484K mutations in the receptor binding domain (RBD) of the spike protein in the wild type SARS-COV-2 virus have resulted, among others, in the following variants: B.1.160 (20A or EU2, first reported in continental Europe), B1.1.7 (α or 20I501Y.V1, first reported in the United Kingdom), B.1.351 (β or 20H/501Y.V2, first reported in South Africa), B.1.1.28.1 (γ or P.1 or 20J/501Y.V3, first reported in Brazil), and B.1.1.28.2 (ζ, or P.2 or 20B/S484K, also first reported in Brazil). From the analysis of a set of bonding descriptors firmly rooted in the formalism of quantum mechanics, including Natural Bond Orbitals (NBO), Quantum Theory of Atoms In Molecules (QTAIM) and highly correlated energies within the Domain Based Local Pair Natural Orbital Coupled Cluster Method (DLPNO-CCSD(T)), and from a set of computed electronic spectral patterns with environmental effects, we show that the new variants improve their ability to recognize available sites to either hydrogen bond or to form salt bridges with residues in the ACE2 receptor of the host cells. This results in significantly improved initial virus⋅⋅⋅cell molecular recognition and attachment at the microscopic level, which trigger the infectious cycle.

Abstract
There is a need for new, cost-effective drugs to treat leishmaniasis. A strategy based on traditional medicine practiced in Bolivia led to the discovery of the 2-substituted quinoline series as a source of molecules with antileishmanial activity and low toxicity. This review documents the development of the series from the first isolated natural compounds through several hundred synthetized molecules to an optimized compound exhibiting an in vitro IC50 value of 0.2 µM against Leishmania donovani, and a selectivity index value of 187, together with in vivo activity on the L. donovani/hamster model. Attempts to establish structure–activity relationships are described, as well as studies that have attempted to determine the mechanism of action. For the latter, it appears that molecules of this series act on multiple targets, possibly including the immune system, which could explain the observed lack of drug resistance after in vitro drug pressure. We also show how nanotechnology strategies could valorize these drugs through adapted formulations and how a mechanistic targeting approach could generate new compounds with increased activity.

Analysis of Conformational Preferences in Caffeine. Molecules 2022; 27:molecules27061937.

Abstract
High level DLPNO−CCSD(T) electronic structure calculations with extended basis sets over B3LYP−D3 optimized geometries indicate that the three methyl groups in caffeine overcome steric hindrance to adopt uncommon conformations, each one placing a C−H bond on the same plane of the aromatic system, leading to the C−H bonds eclipsing one carbonyl group, one heavily delocalized C−N bond constituent of the fused double ring aromatic system, and one C−H bond from the imidazole ring. Deletion of indiscriminate and selective non-Lewis orbitals unequivocally show that hyperconjugation in the form of a bidirectional −CH3 ⇆ aromatic system charge transfer is responsible for these puzzling conformations. The structural preferences in caffeine are exclusively determined by orbital interactions, ruling out electrostatics, induction, bond critical points, and density redistribution because the steric effect, the allylic effect, the Quantum Theory of Atoms in Molecules (QTAIM), and the non-covalent interactions (NCI), all predict wrong energetic orderings. Tiny rotational barriers, not exceeding 1.3 kcal/mol suggest that at room conditions, each methyl group either acts as a free rotor or adopts fluxional behavior, thus preventing accurate determination of their conformations. In this context, our results supersede current experimental ambiguity in the assignation of methyl conformation in caffeine and, more generally, in methylated xanthines and their derivatives.

Abstract
Purpose:
Hydrazones are a class of azomethines with a wide spectrum of pharmacological properties which are influenced by pH
of the media. The purpose of this study was investigation of acid-base properties of five 4-nitrobenzaldehyde-4-substitutedphenyl1-carbonylhydrazones in sodium hydroxide media (14>pH>7).
Method:
The dissociation process was followed by UV-Vis spectroscopy, in the ethanol-water (V/V, 1:1) solutions, at room
temperature. Semiempirical methods AM1 and PM3 were applied for determination of the deprotonation enthalpies.
Results:
The changes in the UV-Vis spectra, as well as the deprotonation enthalpies, suggested that the
dissociation process for four investigated hydrazones with an amide group took place in one step. The
exception with two dissociation steps was hydrazone with amide and hydroxyl group. The pH region of
dissociation was from pH 10.8 to pH 11.6 for the first step and between pH 11.7 and pH 12.1 for the
second step of dissociation. The influence of the ethanol on the UV-Vis spectra was eliminated by the
method of Characteristic Vector Analyses (CVA). The stoichiometric dissociation constants were determined
numerically (pKHA = n·pH + logI) and graphically (intercept of the dependence of logI on
pH) from the absorbance data using experimental and reconstructed UV-Vis spectra, at three different
ionic strengths. Thermodynamic dissociation constants were estimated graphically as an intercept of
dependence of dissociation constant on the square root of the ionic strength.
Conclusion:
The obtained results demonstrated that the influence of the substituents on pKHA values
was not significant, except for hydrazone with amide and hydroxyl group. Namely, the dissociation of
the amide group of this hydrazone was retarded due to the influence of the phenolic group.

Abstract
Background:
QSAR study of p-substituted aromatic hydrazones was performed to
estimate the quantitative effects of selected topological descriptors on their antimicrobial activity.
None of the hydrazones inhibited the growth of the Aspergillus spp., while the data obtained with
regard to the antifungal activity of the compounds against Candida utilis were insufficient to develop
reliable statistical QSAR models. Therefore, the investigation was focused on developing QSAR
models for predicting the antibacterial activity of the compounds against Bacillus subtilis.
Methods:
A set of substituted hydrazones were tested for their in vitro growth inhibitory activity
against Candida utilis, Bacillus subtilis and Aspergillus niger and the diameter of the inhibition zone
(mm) was measured. The inhibitory activity data, determined in μg/mL, were transformed to the
negative logarithms of molar MICs (log1/CMIC). Using Marvinsketch software package, 28
topological descriptors were calculated. Statistical parameters, such as R2, Sd, F-test, R2
adj, Q, SPRESS,
PSE and Q2, were used to test the quality of the developed two-, three-, four-parametric and higher
QSAR models.
Results and Conclusion:
Statistical evaluation of the data used to test the quality of the obtained
QSAR models indicated that the two-parametric model involving the descriptors Atom Count (AC)
and Maximal Projection Area (MAPA) was statistically significant when all the statistical parameters
were summarized. The two parameters, AC and MAPA, had opposite input in modeling the
antimicrobial activity of the selected hydrazones against Bacillus subtilis.

Abstract
An exploration of the antioxidant power of curcumin, demethoxycurcumin, and bisdemethoxycurcumin, three natural antioxidants found in Curcuma longa, is reported in this work. We exhaust all structural possibilities leading to intramolecular hydrogen bonding and evaluate 15 isomers in total. Calculations were carried out in the gas phase and in the presence of solvents (water, to mimic biological media, and ethanol, to reproduce experimental assays) following the hydrogen atom transfer (HAT) and single electron transfer (SET) mechanisms. CH3OH-O hydrogen bonds are directly related to the antioxidant power via both mechanisms. We provide evidence to explain the experimental observations and to understand the fundamental factors driving antioxidant activity from a molecular perspective. Noticeably, the solvent enhances the antioxidant power in every case. All structures considered here are predicted to have better antioxidant abilities than phenol, and come very close to or surpass vitamin E.
