BMC Chem 2024; 18:52. [PMID: 38486282 PMCID: PMC10941513 DOI: 10.1186/s13065-024-01136-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2023] [Accepted: 02/05/2024] [Indexed: 03/17/2024] Open
Abstract
Various sets of thiazole, thiophene, and 2-pyridone ring structures containing a dimethylaniline component were synthesized. Substituted thiazoles 2-3 and thiophenes 5-7 were produced by reacting thiocarbamoyl compound 4 with α-halogenated reagents in different basic conditions. Also, a series of 2-pyridone derivatives 9a-f substituted with dimethylaniline was synthesized through Michael addition of malononitrile to α,β-unsaturated nitrile derivatives 8a-f. The synthesized products were structurally proven by spectroscopic methods such as IR, 1H NMR, 13C NMR, and MS data. Furthermore, the anti-cancer efficacy of the compounds was assessed using the MTT assay on two cell lines: hepatocellular carcinoma (HepG-2) and breast cancer (MDA-MB-231). The results showed the highest growth inhibition for derivatives 2, 6, 7, and 9c, which were further examined for their IC50 values. The IC50 for compound 2 showed equipotent activity (IC50 = 1.2 µM) against the HepG-2 cell line compared to Doxorubicin (IC50 = 1.1 µM). Compounds 2, 6, 7 and 9c showed very good ADME assessments for further drug administration. Moreover, the PASS theoretical prediction for the compounds showed high antimitotic and antineoplastic activities for compounds 2, 6, 7, and 9c, as well as potent inhibition activity for the insulysin enzyme (IDE). Molecular docking stimulations were performed on CDK1/CyclinB1/CKS2 (PDB ID: 4y72) and BPTI (PDB ID: 2ra3). When docked into (PDB ID: 4y72), all of the tested compounds showed considerable inhibition, and the 2-pyridone derivative 9d had the maximum binding affinity (- 8.1223 kcal/mol). While thiophene derivative 6 offered the maximum binding affinity (- 7.5094 kcal/mol) when docked into (PDB ID: 2ra3).

Abstract
Isoquinoline derivatives having some nucleosidic structural features are considered as candidate choices for effective remediation of the different severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections and their following disease, the coronavirus disease 2019 (COVID-19). SLL-0197800 is a recently discovered isoquinoline compound with potential strong universal anticoronaviral activities against SARS-CoV-2 and its previous strains. SLL-0197800 nonspecifically hits the main protease (Mpro) enzyme of the different coronaviruses. Herein in the present study, we tested the probability of the previous findings of this experimental agent to be extended to comprise any coronavirus through concurrently disrupting the mutable-less replication enzymes like the RNA-dependent RNA polymerase (RdRp) protein as well as the 3'-to-5' exoribonuclease (ExoN) protein. The in vitro anti-RdRp/ExoN assay revealed the potent inhibitory activities of SLL-0197800 on the coronaviral replication with minute values of anti-RdRp and anti-RdRp/ExoN EC50 (about 0.16 and 0.27 μM, respectively). The preliminary in silico outcomes significantly supported these biochemical findings. To put it simply, the present important results of these extension efforts greatly reinforce and extend the SLL-0197800's preceding findings, showing that the restraining/blocking actions (i.e., inhibitory activities) of this novel investigational anti-SARS-CoV-2 agent against the Mpro protein could be significantly extended against other copying and multiplication enzymes such as RdRp and ExoN, highlighting the potential use of SLL-0197800 against the coming versions of the homicidal coronavirus (if any), i.e., revealing the probable nonspecific anticoronaviral features and qualities of this golden experimental drug against nearly any coronaviral strain, for instance, SARS-CoV-3.

Abstract
Protein-protein interactions (PPI) represent attractive targets for drug design. Thus, aiming at a deeper insight into the HSV-1 envelope glycoprotein D (gD), protein-protein docking and dynamic simulations of gD-HVEM and gD-Nectin-1 complexes were performed. The most stable complexes and the pivotal key residues useful for gD to anchor human receptors were identified and used as starting points for a structure-based virtual screening on a library of both synthetic and designed 1,2,3-triazole-based compounds. Their binding properties versus gD interface with HVEM and Nectin-1 along with their structure-activity relationships (SARs) were evaluated. Four [1,2,3]triazolo[4,5-b]pyridines were identified as potential HSV-1 gD inhibitors, for their good theoretical affinity towards all conformations of HSV-1 gD. Overall, this study suggests promising basis for the design of new antiviral agents targeting gD as a valuable strategy to prevent viral attachment and penetration into the host cell.

Phenylpyrazolone-1,2,3-triazole Hybrids as Potent Antiviral Agents with Promising SARS-CoV-2 Main Protease Inhibition Potential. Pharmaceuticals (Basel) 2023; 16:ph16030463.

Abstract
COVID-19 infection is now considered one of the leading causes of human death. As an attempt towards the discovery of novel medications for the COVID-19 pandemic, nineteen novel compounds containing 1,2,3-triazole side chains linked to phenylpyrazolone scaffold and terminal lipophilic aryl parts with prominent substituent functionalities were designed and synthesized via a click reaction based on our previous work. The novel compounds were assessed using an in vitro effect on the growth of SARS-CoV-2 virus-infested Vero cells with different compound concentrations: 1 and 10 μM. The data revealed that most of these derivatives showed potent cellular anti-COVID-19 activity and inhibited viral replication by more than 50% with no or weak cytotoxic effect on harboring cells. In addition, in vitro assay employing the SARS-CoV-2-Main protease inhibition assay was done to test the inhibitors' ability to block the common primary protease of the SARS-CoV-2 virus as a mode of action. The obtained results show that the one non-linker analog 6h and two amide-based linkers 6i and 6q were the most active compounds with IC50 values of 5.08, 3.16, and 7.55 μM, respectively, against the viral protease in comparison to data of the selective antiviral agent GC-376. Molecular modeling studies were done for compound placement within the binding pocket of protease which reveal conserved residues hydrogen bonding and non-hydrogen interactions of 6i analog fragments: triazole scaffold, aryl part, and linker. Moreover, the stability of compounds and their interactions with the target pocket were also studied and analyzed by molecular dynamic simulations. The physicochemical and toxicity profiles were predicted, and the results show that compounds behave as an antiviral activity with low or no cellular or organ toxicity. All research results point to the potential usage of new chemotype potent derivatives as promising leads to be explored in vivo that might open the door to rational drug development of SARS-CoV-2 Main protease potent medicines.

Novel Investigational Anti-SARS-CoV-2 Agent Ensitrelvir "S-217622": A Very Promising Potential Universal Broad-Spectrum Antiviral at the Therapeutic Frontline of Coronavirus Species. ACS OMEGA 2023; 8:5234-5246. [PMID: 36798145 PMCID: PMC9897045 DOI: 10.1021/acsomega.2c03881] [Citation(s) in RCA: 25] [Impact Index Per Article: 25.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/21/2022] [Accepted: 08/05/2022] [Indexed: 06/06/2023]
Abstract
Lately, nitrogenous heterocyclic antivirals, such as nucleoside-like compounds, oxadiazoles, thiadiazoles, triazoles, quinolines, and isoquinolines, topped the therapeutic scene as promising agents of choice for the treatment of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections and their accompanying ailment, the coronavirus disease 2019 (COVID-19). At the same time, the continuous emergence of new strains of SARS-CoV-2, like the Omicron variant and its multiple sublineages, resulted in a new defiance in the enduring COVID-19 battle. Ensitrelvir (S-217622) is a newly discovered orally active noncovalent nonpeptidic agent with potential strong broad-spectrum anticoronaviral activities, exhibiting promising nanomolar potencies against the different SARS-CoV-2 variants. S-217622 effectively and nonspecifically hits the main protease (Mpro) enzyme of a broad scope of coronaviruses. Herein, in the present computational/biological study, we tried to extend these previous findings to prove the universal activities of this investigational agent against any coronavirus, irrespective of its type, through synchronously acting on most of its main unchanged replication enzymes/proteins, including (in addition to the Mpro), e.g., the highly conserved RNA-dependent RNA polymerase (RdRp) and 3'-to-5' exoribonuclease (ExoN). Biochemical evaluation proved, using the in vitro anti-RdRp/ExoN bioassay, that S-217622 can potently inhibit the replication of coronaviruses, including the new virulent strains of SARS-CoV-2, with extremely minute in vitro anti-RdRp and anti-RdRp/ExoN half-maximal effective concentration (EC50) values of 0.17 and 0.27 μM, respectively, transcending the anti-COVID-19 drug molnupiravir. The preliminary in silico results greatly supported these biochemical results, proposing that the S-217622 molecule strongly and stabilizingly strikes the key catalytic pockets of the SARS-CoV-2 RdRp's and ExoN's principal active sites predictably via the nucleoside analogism mode of anti-RNA action (since the S-217622 molecule can be considered as a uridine analog). Moreover, the idealistic druglikeness and pharmacokinetic characteristics of S-217622 make it ready for pharmaceutical formulation with the expected very good clinical behavior as a drug for the infections caused by coronaviruses, e.g., COVID-19. To cut it short, the current critical findings of this extension work significantly potentiate and extend the S-217622's previous in vitro/in vivo (preclinical) results since they showed that the striking inhibitory activities of this novel anti-SARS-CoV-2 agent on the Mpro could be extended to other replication enzymes like RdRp and ExoN, unveiling the possible universal use of the compound against the next versions of the virus (i.e., disclosing the nonspecific anticoronaviral properties of this compound against almost any coronavirus strain), e.g., SARS-CoV-3, and encouraging us to rapidly start the compound's vast clinical anti-COVID-19 evaluations.

Abstract
The possibility of functionalization of 2-(polyfluorophenyl)-4H-chromen-4-ones, with them having different numbers of fluorine atoms, with 1,2,4-triazole or imidazole under conditions of base-promoted nucleophilic aromatic substitution has been shown. A high selectivity of mono-substitution was found with the use of an azole (1.5 equiv.)/NaOBut(1.5 equiv.)/MeCN system. The structural features of fluorinated mono(azolyl)-substituted flavones in crystals were established using XRD analysis. The ability of penta- and tetrafluoroflavones to form persubstituted products with triazole under azole (6 equiv.)/NaOBut(6 equiv.)/DMF conditions was found in contrast to similar transformations with imidazole. On the basis of mono(azolyl)-containing polyfluoroflavones in reactions with triazole and pyrazole, polynuclear hybrid compounds containing various azole fragments were obtained. For poly(pyrazolyl)-substituted flavones, green emission in the solid state under UV-irradiation was found, and for some derivatives, weak fungistatic activity was found.

Abstract
AIMS We have established this paper to recommend a novel way for the preparation of carbohydrates encompassing a 1,2,3-triazole motif that was prepared using an efficient click chemistry synthesis. BACKGROUND The SARS-CoV-2 coronavirus epidemic continues to spread at a fast rate worldwide. The main protease (Mpro) is useful target for anti-COVID-19 agents. Triazoles are frequently found in many bioactive products, such as coronavirus inhibitors. OBJECTIVE Click reactions are facilitated via the activation of copper nanoparticles, different substrates have been tested using this adopted procedure given in all cases, in high yields and purity. Other interesting comparative docking analyses will be the focus of this article. Calculations of quantitative structure-activity relationships will be studied. METHODS Copper nanoparticles were produced by the reaction of cupric acetate monohydrate with oleylamine and oleic acid. To a solution, 5-(azidomethyl)-2,2,7,7-tetramethyltetrahydro-5Hbis([ 1,3]dioxolo)[4,5-b:4',5'-d]pyran 2 (200 mg, 0.72 mmol, 1 eq.) in toluene (15 mL) was added into a mixture of N-(prop-2-yn-1-yl)benzamide derivatives 1a-d (1.5 eq.) and copper nanoparticles (0.57 mg, 0.036 mmol, 0.05 eq.). RESULTS A novel series of 1,2,3-triazole carbohydrate skeletons were modeled and efficiently synthesized. Based on the observations, virtual screening using molecular docking was performed to identify novel compounds that can bind with the protein structures of COVID-19 (PDB ID: 6LU7 and 6W41). We believed that the 1,2,3-triazole carbohydrate derivatives could aid in COVID-19 drug discovery. CONCLUSION The formations of targeted triazoles were confirmed by different spectroscopic techniques (FT-IR, 1H NMR, 13C NMR, and CHN analyses). The docking scores of the newly synthesized triazole are attributed to the presence of hydrogen bonds together with many interactions between the ligands and the active amino acid residue of the receptor. The comparison of the interactions of the drugs, remdesivir and triazole, in the largest pocket of 6W41 and 6LU7 is also presented.

Abstract
A large number of pharmaceuticals and personal care products (PPCPs) persist in wastewater, and the consumption of PPCPs for COVID-19 control and prevention has sharply increased during the pandemic. This study investigated the occurrence, removal efficiency, and risk assessment of six typical PPCPs commonly used in China in two wastewater treatment plants (WWTPs). Ribavirin (RBV) is an effective pharmaceutical for severely ill patients with COVID-19, and the possible biodegradation pathway of RBV by activated sludge was discovered. The experimental results showed that PPCPs were detected in two WWTPs with a detection rate of 100% and concentrations ranging between 612 and 2323 ng L-1. The detection frequency and concentrations of RBV were substantially higher, with a maximum concentration of 314 ng L-1. Relatively high pollution loads were found for the following PPCPs from influent: ibuprofen > ranitidine hydrochloride > RBV > ampicillin sodium > clozapine > sulfamethoxazole. The removal efficiency of PPCPs was closely related to adsorption and biodegradation in activated sludge, and the moving bed biofilm reactor (MBBR) had a higher removal capacity than the anoxic-anaerobic-anoxic-oxic (AAAO) process. The removal efficiencies of sulfamethoxazole, ampicillin sodium, ibuprofen, and clozapine ranged from 92.21% to 97.86% in MBBR process and were relatively low, from 61.82% to 97.62% in AAAO process, and the removal of RBV and ranitidine hydrochloride were lower than 42.96% in both MBBR and AAAO processes. The discrepancy in removal efficiency is caused by temperature, hydrophilicity, and hydrophobicity of the compound, and acidity and alkalinity. The transformation products of RBV in activated sludge were detected and identified, and the biodegradation process of RBV could be speculated as follows: first breaks into TCONH2 and an oxygen-containing five-membered heterocyclic ring under the nucleosidase reaction, and then TCONH2 is finally formed into TCOOH through amide hydrolysis. Aquatic ecological risks based on risk quotient (RQ) assessment showed that PPCPs had high and medium risks in the influent, and the RQ values were all reduced after MBBR and AAAO treatment. Ranitidine hydrochloride and clozapine still showed high and medium risks in the effluent, respectively, and thus presented potential risks to the aquatic ecosystem.

Singh R, Bhardwaj VK, Das P, Bhattacherjee D, Zyryanov GV, Purohit R. Benchmarking the ability of novel compounds to inhibit SARS-CoV-2 main protease using steered molecular dynamics simulations. Comput Biol Med 2022; 146:105572. [PMID: 35551011 PMCID: PMC9052739 DOI: 10.1016/j.compbiomed.2022.105572] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2022] [Revised: 04/25/2022] [Accepted: 04/26/2022] [Indexed: 01/31/2023]
Abstract
BACKGROUND The SARS-CoV-2 main protease (Mpro) is an attractive target in the COVID-19 drug development process. It catalyzes the polyprotein's translation from viral RNA and specifies a particular cleavage site. Due to the absence of identical cleavage specificity in human cell proteases, targeting Mpro with chemical compounds can obstruct the replication of the virus. METHODS To explore the potential binding mechanisms of 1,2,3-triazole scaffolds in comparison to co-crystallized inhibitors 11a and 11b towards Mpro, we herein utilized molecular dynamics and enhanced sampling simulation studies. RESULTS AND CONCLUSION All the 1,2,3-triazole scaffolds interacted with catalytic residues (Cys145 and His41) and binding pocket residues of Mpro involving Met165, Glu166, Ser144, Gln189, His163, and Met49. Furthermore, the adequate binding free energy and potential mean force of the topmost compound 3h was comparable to the experimental inhibitors 11a and 11b of Mpro. Overall, the current analysis could be beneficial in developing the SARS-CoV-2 Mpro potential inhibitors.

Fluorinated Analogues of Lepidilines A and C: Synthesis and Screening of Their Anticancer and Antiviral Activity. MOLECULES (BASEL, SWITZERLAND) 2022; 27:molecules27113524.

Abstract
Starting with fluorinated benzylamines, a series of 2-unsubstituted imidazole N-oxides was prepared and subsequently deoxygenated in order to prepare the corresponding imidazoles. The latter were treated with benzyl halides yielding imidazolium salts, which are considered fluorinated analogues of naturally occurring imidazolium alkaloids known as lepidilines A and C. A second series of oxa-lepidiline analogues was obtained by O-benzylation of the initially synthetized imidazole N-oxides. Both series of imidazolium salts were tested as anticancer and antiviral agents. The obtained results demonstrated that the introduction of a fluorine atom, fluoroalkyl or fluoroalkoxy substituents (F, CF3 or OCF3) amplifies cytotoxic properties, whereas the cytotoxicity of some fluorinated lepidilines is promising in the context of drug discovery. All studied compounds revealed a lack of antiviral activity against the investigated viruses in the nontoxic concentrations.

Abstract
COVID-19 is a global pandemic caused by infection with the SARS-CoV-2 virus. Remdesivir, a SARS-CoV-2 RNA polymerase inhibitor, is the only drug to have received widespread approval for treatment of COVID-19. The SARS-CoV-2 main protease enzyme (MPro), essential for viral replication and transcription, remains an active target in the search for new treatments. In this study, the ability of novel thiazolyl-indazole derivatives to inhibit MPro is evaluated. These compounds were synthesized via the heterocyclization of phenacyl bromide with (R)-carvone, (R)-pulegone and (R)-menthone thiosemicarbazones. The binding affinity and binding interactions of each compound were evaluated through Schrödinger Glide docking, AMBER molecular dynamics simulations, and MM-GBSA free energy estimation, and these results were compared with similar calculations of MPro binding various 5-mer substrates (VKLQA, VKLQS, VKLQG) and a previously identified MPro tight-binder X77. From these simulations, we can see that binding is driven by residue specific interactions such as π-stacking with His41, and S/π interactions with Met49 and Met165. The compounds were also experimentally evaluated in a MPro biochemical assay and the most potent compound containing a phenylthiazole moiety inhibited protease activity with an IC50 of 92.9 μM. This suggests that the phenylthiazole scaffold is a promising candidate for the development of future MPro inhibitors.

Abstract
Cancer is one of the major causes of death across the world. Cancer is a broad word that encompasses a wide range of illnesses that can affect any part of the body. Cancer research has increased understanding of molecular biology and cellular biology, resulting in new cancer therapies. Despite of adverse effects, surgery, radiation, and anticancer medicines are the modern cancer treatments. Keeping in mind the excellent anticancer activity exhibited by various heterocyclics, various medicines with heterocyclic moiety have been developed to identify particular target regions. The chapter aims to discuss new discoveries in the field of anticancer pharmaceuticals comprising the thiazole, pyrazole, oxazole, and triazole rings over the last five years. The proposed anticancer drugs have a lot of future significance due to their high potency.

Abstract
The SARS-CoV-2 virus is highly contagious to humans and has caused a pandemic of global proportions. Despite worldwide research efforts, efficient targeted therapies against the virus are still lacking. With the ready availability of the macromolecular structures of coronavirus and its known variants, the search for anti-SARS-CoV-2 therapeutics through in silico analysis has become a highly promising field of research. In this study, we investigate the inhibiting potentialities of triazole-based compounds against the SARS-CoV-2 main protease (Mpro). The SARS-CoV-2 main protease (Mpro) is known to play a prominent role in the processing of polyproteins that are translated from the viral RNA. Compounds were pre-screened from 171 candidates (collected from the DrugBank database). The results showed that four candidates (Bemcentinib, Bisoctrizole, PYIITM, and NIPFC) had high binding affinity values and had the potential to interrupt the main protease (Mpro) activities of the SARS-CoV-2 virus. The pharmacokinetic parameters of these candidates were assessed and through molecular dynamic (MD) simulation their stability, interaction, and conformation were analyzed. In summary, this study identified the most suitable compounds for targeting Mpro, and we recommend using these compounds as potential drug molecules against SARS-CoV-2 after follow up studies.
