In vitro anti-trypanosomal activity of synthetic nitrofurantoin-triazole hybrids against Trypanosoma species causing human African trypanosomosis. Fundam Clin Pharmacol 2024; 38:72-83.

Abstract
Human African trypanosomosis (HAT) which is also known as sleeping sickness is caused by Trypanosoma brucei gambiense that is endemic in western and central Africa and T. b. rhodesiense that is endemic in eastern and southern Africa. Drugs used for treatment against HAT first stage have limited effectiveness, and the second stage drugs have been reported to be toxic, expensive, and have time-consuming administration, and parasitic resistance has developed against these drugs. The aim of this study was to evaluate the anti-trypanosomal activity of nitrofurantoin-triazole hybrids against T. b. gambiense and T. b. rhodesiense parasites in vitro. This study screened 19 synthesized nitrofurantoin-triazole (NFT) hybrids on two strains of human trypanosomes, and cytotoxicity was evaluated on Madin-Darby bovine kidney (MDBK) cells. The findings in this study showed that an increase in the chain length and the number of carbon atoms in some n-alkyl hybrids influenced the increase in anti-trypanosomal activity against T. b. gambiense and T. b. rhodesiense. The short-chain n-alkyl hybrids showed decreased activity compared to the long-chain n-alkyl hybrids, with increased activity against both T. b. gambiense and T. b. rhodesiense. Incorporation of additional electron-donating substituents in some NFT hybrids showed increased anti-trypanosomal activity than to electron-withdrawing substituents in NFT hybrids. All 19 NFT hybrids tested displayed better anti-trypanosomal activity against T. b. gambiense than T. b. rhodesiense. The NFT hybrid no. 16 was among the best performing hybrids against both T. b. gambiense (0.08 ± 0.04 μM) and T. b.rhodesiense (0.11 ± 0.06 μM), and its activity might be influenced by the introduction of fluorine in the para-position on the benzyl ring. Remarkably, the NFT hybrids in this study displayed weak to moderate cytotoxicity on MDBK cells. All of the NFT hybrids in this study had selectivity index values ranging from 18 to greater than 915, meaning that they were up to 10-100 times fold selective in their anti-trypanosomal activity. The synthesized NFT hybrids showed strong selectivity >10 to T. b. gambiense and T. b. rhodesiense, which indicates that they qualify from the initial selection criteria for potential hit drugs.

Abstract
A large number of drugs are introduced each year to treat different diseases. Most of the time, patients suffer from more than one health problem which makes it necessary to take multiple drugs. When drugs are combined, the problem of drug-drug interaction becomes relevant. In this work, we studied the drug-drug interaction between escitalopram and ibuprofen or paracetamol using density functional theory and quantum theory of atoms in molecules. The results suggest that following the interactions, the activity of drugs changes according to site of interaction. Most reactive and most stable interactions would be preferable for the purpose of use. The in silico drug-likeness studies show that escitalopram and paracetamol couple is more bioavailable than escitalopram and ibuprofen couple. Moreover, in order to gain additional insights into the mentioned drugs' interactions, the drugs were docked separately and jointly against the potential targets for antidepressants and NSAIDs, namely 6HIS and 2PXX. The molecular docking results showed a potential improvement of the effectiveness of the drugs after combining by forming hydrogen bonds, hydrophobic contacts and π…π stacking.Communicated by Ramaswamy H.

Abstract
Natural products and their derivatives have been sources of search and research for new drugs for the treatment of neglected diseases. Naphthoquinones, a special group of quinones, are products of natural metabolites with a wide spectrum of biological activities and represent a group of interesting molecules for new therapeutic propositions. Among these compounds, lapachol stands out as a molecule from the heartwood of Tabebuia sp. whose structural changes resulted in compounds considered promising, such as epoxy-α-lapachone (ELAP). The biological activity of ELAP has been demonstrated, so far, for parasitic protozoa such as Leishmania spp., Trypanosoma cruzi and Plasmodium spp., species causing diseases needing new drug development and adequate health policy. This work gathers in vitro and in vivo studies on these parasites, as well as the toxicity profile, and the probable mechanisms of action elucidated until then. The potential of ELAP-based technology alternatives for a further drug is discussed here.

Abstract
Quinones are attractive pharmacological scaffolds for developing new agents for the treatment of different transmissible and non-transmissible human diseases due to their capacity to alter the cell redox homeostasis. The bioactivity and potential mode of action of 19 p-quinone derivatives fused to different aromatic rings (carbo or heterocycles) and harboring distinct substituents were investigated in infective Trypanosoma brucei brucei. All the compounds, except for a furanequinone (EC50=38 μM), proved to be similarly or even more potent (EC50 = 0.5-5.5 μM) than the clinical drug nifurtimox (EC50 = 5.3 μM). Three furanequinones and one thiazolequinone displayed a higher selectivity than nifurtimox. Two of these selective hits resulted potent inhibitors of T. cruzi proliferation (EC50=0.8-1.1 μM) but proved inactive against Leishmania infantum amastigotes. Most of the p-quinones induced a rapid and marked intracellular oxidation in T. b. brucei. DFT calculations on the oxidized quinone (Q), semiquinone (Q•-) and hydroquinone (QH2) suggest that all quinones have negative ΔG for the formation of Q•-. Qualitative and quantitative structure-activity relationship analyses in two or three dimensions of different electronic and biophysical descriptors of quinones and their corresponding bioactivities (killing potency and oxidative capacity) were performed. Charge distribution over the quinone ring carbons of Q and Q.- and the frontier orbitals energies of SUMO (Q.-) and LUMO (Q) correlate with their oxidative and trypanocidal activity. QSAR analysis also highlighted that both bromine substitution in the p-quinone ring and a bulky phenyl group attached to the furane and thiazole rings (which generates a negative charge due to the π electron system polarized by the nearby heteroatoms) are favorable for activity. By combining experimental and in silico procedures, this study disclosed important information about p-quinones that may help to rationally tune their electronic properties and biological activities.

Abstract
The proverb "Old is gold" is applicable in drug discovery and the proverb "All that Glitters is not Gold" is also appropriate. In the COVID-19 era, there has been a race for drugs to be effective against SARS-CoV-2. There are reports about the uses of Remdesivir and Favipiravir as existing antivirals against virus but none have been conclusive so far. In the attempts for innovations, the combination of drugs is also under trials. Therefore, we used the density functional theory method and quantum theory of atoms in molecules to investigate drug-drug interactions involving Remdesivir and Favipiravir. The computed parameters were related to the antiviral actions of both drugs together. The results indicate enhanced antiviral activity and it will be worthy to consider additional investigations with the combination of these two drugs.

Abstract
p300/CBP Associated Factor (PCAF), a GNAT family member protein, represent a valid target for therapeutic interventions since its dysfunction has implicated in variety of diseases like cancer, diabetes, inflammatory diseases, etc. Despite its potential for therapeutics, only a small number of PCAF inhibitors were reported. Hence, in this study, the catalytic domain of PCAF was explored to screen novel, potent and cell permeable inhibitor from three small molecule databases like Life Chemical, Maybridge and Chembridge by using Structure Based Virtual Screening (SBVS) method. Further, Induced Fit Docking, Binding Free Energy calculation, Single Point Energy calculation and Molecular Dynamics Simulation were performed on selected hits. In silico results revealed that F2209-0381 has higher binding energy of -109.722 and have greater cell permeability (QPPCaco = 1456.764; QPPMDCK = 742.941) than rest of hits. Cytotoxicity effect and protein expression analysis of F2209-0381 on A549 cells reveals that it exhibited strong inhibition with IC50 value of 58.31 μg/ml and significantly reduced the expression of PCAF after 72 h time point. Thus, this study warrants that F2209-0381 could become a novel, potent and cell permeable drug of PCAF thereby it could combat its mediated diseases.

Abstract
Histone acetyltransferases (HATs) is one among the conspicuous posttranslational modification in eukaryotic cells. p300/CBP Associated Factor (PCAF) and CREB-binding protein (CBP) are the two highly homologous HAT family which are vastly implicated in several diseases like cancer, diabetes, etc. Pentadecylidenemalonate, a simplified analog of anacardic acid, was reported as first mixed inhibitor/activator of HATs which inhibits p300/CBP and activates PCAF. It was appointed earlier as a valuable biological tool to understand the mechanism of lysine acetyltransferases due to its powerful apoptotic effect. In this study, pentadecylidenemalonate was taken for deciphering the binding mode, key interacting residues as well as mechanistic insights on PCAF and CBP as activator and inhibitor, respectively. This study is highly believed to help in rational design on antineoplastic drugs against PCAF. Communicated by Ramaswamy H. Sarma.

Abstract
The structural dynamics and stability of inclusion complexes of mansonone E (ME) and H (MH) including their stereoisomers with various βCDs (methylated- and hydroxypropylated-βCDs) were investigated by classical molecular dynamics (MD) simulations and binding free energy calculations. The simulation results revealed that mansonones are able to form inclusion complexes with βCDs. The guest molecules are not completely inserted into the host cavity, their preferably positions are nearby the secondary rim with the oxane ring dipping into the hydrophobic inner cavity. The encapsulation process leads to a higher rigidity of the βCDs enhancing the intramolecular hydrogen bond formation ability and decreasing the chance of glucopyranose rotation. According to the MM-PBSA binding free energy calculation, all considered inclusion complexes are stable and the binding energies are mainly caused by van der Waals interactions. Moreover, the free energy calculations showed significant differences in the complexation energies for the stereoisomers, which could enable the separation of the isomers by analytical techniques for further pharmaceutical applications.

Abstract
A set of aryloxy-quinones, previously synthesized and evaluated against Trypanosoma cruzi epimastigotes cultures, were found more potent and selective than nifurtimox. One of the possible mechanisms of the trypanocidal activity of these quinones could be inhibition of trypanothione reductase (TR). Considering that glutathione reductase (GR) is the equivalent of TR in humans, biochemical, kinetic, and molecular docking studies in TR and GR were envisaged and compared with the trypanocidal and cytotoxic data of a set of aryloxy-quinones. Biochemical assays indicated that three naphthoquinones (Nq-h, Nq-g, and Nq-d) selectively inhibit TR and the TR kinetic analyses indicated that Nq-h inhibit TR in a noncompetitive mechanism. Molecular dockings were performed in TR and GR in the following three putative binding sites: the catalytic site, the dimer interface, and the nicotinamide adenine dinucleotide phosphate-binding site. In TR and GR, the aryloxy-quinones were found to exhibit high affinity for a site near it cognate-binding site in a place in which the noncompetitive kinetics could be justified. Taking as examples the three compounds with TR specificity (TRS) (Nq-h, Nq-g, and Nq-d), the presence of a network of contacts with the quinonic ring sustained by the triad of Lys62, Met400', Ser464' residues, seems to contribute hardly to the TRS. Compound Nq-b, a naphthoquinone with nitrophenoxy substituent, proved to be the best scaffold for the design of trypanocidal compounds with low toxicity. However, the compound displayed only a poor and non-selective effect toward TR indicating that TR inhibition is not the main reason for the antiparasitic activity of the aryloxy-quinones.

Abstract
Biflorin 1 is a biologically active quinone, isolated from Capraria biflora. Five new biflorin-based nitrogen derivatives were synthesized, of which two were mixtures of (E)- and (Z)- isomers: (Z)-2a, (Z)-2b, (Z)-3a, (Z)- and (E)-3b, (Z)- and (E)-3c. The antibacterial activity was investigated using the microdilution method for determining the minimum inhibitory concentration (MIC) against six bacterial strains. Tests have shown that these derivatives have potential against all bacterial strains. The cytotoxic activity was also evaluated against three strains of cancer cells, but none of the derivatives showed activity.

Abstract
Naphthoquinones are considered privileged structures for anticancer drug molecules. The Heck reaction of 2-hydroxy-1,4-naphthoquinone (lawsone) with 1-bromo-3-methyl-2-butene offered easy access to lapachol. Several naturally occurring linear and angular heterocyclic quinoids (α-lapachone, β-lapachone, dunnione, and related analogues) were prepared from lapachol. Furthermore, we demonstrated that the synthetic naphthoquinones inhibit cell proliferation in human leukemia HL-60 cells. In particular, angular-type derivatives were found to possess moderate cytotoxicity and to elevate the levels of intracellular glutathione disulfide (GSSG). Our work highlights the significant potential of naturally occurring angular-series naphthoquinones as antileukemic agents.

Abstract
In our continued search for novel trypanocidal compounds, twenty-six derivatives of para- and ortho-naphthoquinones coupled to 1,2,3-triazoles were synthesized. These compounds were evaluated against the infective bloodstream form of Trypanosoma cruzi, the etiological agent of Chagas disease. Compounds 17-24, 28-30 and 36-38 are described herein for the first time. Three of these novel compounds (28-30) were found to be more potent than the standard drug benznidazole, with IC50/24h values between 6.8 and 80.8μM. Analysis of the toxicity to heart muscle cells led to LC50/24h of <125, 63.1 and 281.6μM for 28, 29 and 30, respectively. Displaying a selectivity index of 34.3, compound 30 will be further evaluated in vivo. The electrochemical properties of selected compounds were evaluated in an attempt to find correlations with trypanocidal activity, and it was observed that more electrophilic quinones were generally more potent.

Abstract
The available chemotherapy for Chagas disease, caused by Trypanosoma cruzi, is unsatisfactory; therefore, there is an intense effort to find new drugs for the treatment of this disease. In our laboratory, we have analyzed the effect on bloodstream trypomastigotes of 16 new naphthoquinone analogues of β-lapachone modified in the pyran ring, aiming to find a new prototype with high trypanocidal activity. The new compounds presented a broad spectrum of activity, and five of them presented IC(50)/24 h in the range of 22-63 μM, whereas β-lapachone had a higher value of 391.5 ± 16.5 μM.
