Fundam Clin Pharmacol 2024; 38:410-464. [PMID: 38146774 DOI: 10.1111/fcp.12974] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2023] [Revised: 09/25/2023] [Accepted: 11/10/2023] [Indexed: 12/27/2023]
Abstract
BACKGROUND Benzothiazole derivatives have been reported to possess a wide range of biological activities, including antimalarial activity. This systematic review aims to summarize and evaluate the antimalarial activities of benzothiazole analogs. METHODS We conducted an electronic search using nine databases in October 2017 and subsequently updated in September 2022. We included all original in vitro and in vivo studies that documented the antimalarial activities of compounds containing benzothiazole analogs with no restriction. The risk of bias of each included study was assessed by ToxRTool. RESULTS Twenty-eight articles were included in our study, which are in vitro, in vivo, or both. Of these, 232 substances were identified to have potent antiplasmodial activity against various strains of the malaria parasite. Benzothiazole analogs show different antimalarial mechanisms, including inhibition of Plasmodium falciparum enzymes in in vitro studies and inhibition of blood parasites in in vivo studies. CONCLUSIONS Benzothiazole derivatives are promising substances for treating malaria. The structure-activity relationship studies suggest that the substitution pattern of the benzothiazole scaffold plays a crucial role in determining the antimalarial activity of the analog.

BMC Chem 2024; 18:9. [PMID: 38191485 PMCID: PMC10775556 DOI: 10.1186/s13065-023-01111-0] [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: 02/17/2023] [Accepted: 12/22/2023] [Indexed: 01/10/2024] Open
Abstract
Pyrazole-bearing compounds are known for their diverse pharmacological effects including potent antileishmanial and antimalarial activities. Herein, some hydrazine-coupled pyrazoles were successfully synthesized and their structures were verified by employing elemental microanalysis, FTIR, and 1H NMR techniques. The in vitro antileishmanial and in vivo antimalarial activities of the synthesized pyrazole derivatives (9-15) were evaluated against Leishmania aethiopica clinical isolate and Plasmodium berghei infected mice, respectively. The result revealed that compound 13 displayed superior antipromastigote activity (IC50 = 0.018) that was 174- and 2.6-fold more active than the standard drugs miltefosine (IC50 = 3.130) and amphotericin B deoxycholate (IC50 = 0.047). The molecular docking study conducted on Lm-PTR1, complexed with Trimethoprim was acquired from the Protein Data Bank (PDB ID:2bfm), justified the better antileishmanial activity of compound 13. Furthermore, the target compounds 14 and 15 elicited better inhibition effects against Plasmodium berghei with 70.2% and 90.4% suppression, respectively. In conclusion, the hydrazine-coupled pyrazole derivatives may be considered potential pharmacophores for the preparation of safe and effective antileishmanial and antimalarial agents.

Abstract
Malaria poses a severe public health risk and a significant economic burden in disease-endemic countries. One of the most severe issues in malaria control is the development of drug resistance in malaria parasites. The standard treatment for malaria is artemisinin-combination therapy (ACT). Nevertheless, the Plasmodium parasite's extensive resistance to prior drugs and reduced ACT efficiency necessitates novel drug discovery. The progress in discovering novel, affordable, and effective antimalarial agents is significant in combating drug resistance, and the hybrid drug concept can be used to covalently link two or more active pharmacophores that may act on multiple targets. Pyrazole and pyrazoline derivatives are considered pharmacologically necessary active heterocyclic scaffolds that possess almost all types of pharmacological activities. This review summarized recent progress in antimalarial activities of synthesized pyrazole and pyrazoline derivatives. The studies published since 2000 are included in this systematic review. This review is anticipated to be beneficial for future study and new ideas in searching for rational development strategies for more effective pyrazole and pyrazoline derivatives as antimalarial drugs.

Abstract
Malaria remains a major vector borne disease claiming millions of lives worldwide due to infections caused by Plasmodium sp. Discovery and development of antimalarial drugs have previously been dominated majorly by single drug therapy. The malaria parasite has developed resistance against first line and second line antimalarial drugs used in the single drug therapy. This has drawn attention to find ways to alleviate the disease burden supplanted by combination therapy with multiple drugs to overcome drug resistance. Emergence of resistant strains even against the combination therapy has now mandated the revision of the current antimalarial pharmacotherapy. Research efforts of the past decade led to the discovery and identification of several new structural classes of antimalarial agents with improved biological attributes over the older ones. The following is a comprehensive review, addressed to the new structural classes of heterocyclic and natural compounds that have been identified during the last decade as antimalarial agents. Some of the classes included herein contain one or more pharmacophores amalgamated into a single bioactive scaffold as antimalarial agents, which act upon the conventional and novel targets.

Abstract
A new family of pyrazole-based compounds (1–15) was synthesized and characterized using different physicochemical analyses, such as FTIR, UV-Visible, 1H, 13C NMR, and ESI/LC-MS. The compounds were evaluated for their in vitro antifungal and antibacterial activities against several fungal and bacterial strains. The results indicate that some compounds showed excellent antibacterial activity against E. coli, S. aureus, C. freundii, and L. monocytogenes strains. In contrast, none of the compounds had antifungal activity. Molecular electrostatic potential (MEP) map analyses and inductive and mesomeric effect studies were performed to study the relationship between the chemical structure of our compounds and the biological activity. In addition, molecular docking and virtual screening studies were carried out to rationalize the antibacterial findings to characterize the modes of binding of the most active compounds to the active pockets of NDM1 proteins.

Abstract
Two novel chemotherapeutic chalcones were synthesized and their structures were confirmed by different spectral tools. Theoretical studies such as molecular modeling were done to detect the mechanism of action of these compounds. In vitro cytotoxicity showed a strong effect against all tested cell lines (MCF7, A459, HepG2, and HCT116), and low toxic effect against normal human melanocytes (HFB4). The lung carcinoma cell line was chosen for further molecular studies. Real-time PCR demonstrated that the two compounds upregulated gene expression of (BAX, p53, casp-3, casp-8, casp-9) genes and decreased the expression of anti-apoptotic genes bcl2, CDK4, and MMP1. Flow-cytometry indicated that cell cycle arrest of A459 was induced at the G2/M phase and the apoptotic percentage increased significantly compared to the control sample. Cytochrome c oxidase and VEGF enzyme activity were detected by ELISA assay. SEM tool was used to follow the morphological changes that occurred on the cell surface, cell granulation, and average roughness of the cell surface. The change in the number and morphology of mitochondria, cell shrinkage, increase in the number of cytoplasmic organelles, membrane blebbing, chromatin condensation, and apoptotic bodies were observed using TEM. The obtained data suggested that new chalcones exerted their pathways on lung carcinoma through induction of two pathways of apoptosis. Graphical abstract Novel chalcones were prepared and confirmed by different spectral tools. Docking simulations were done to detect the mechanism of action. In vitro cytotoxicity indicated a strong effect against different cancer cell lines and low toxic effects against normal human melanocytes (HFB4). The lung carcinoma cell line was chosen for further molecular studies that include Real-time PCR, Flow-cytometry, Cytochrome c oxidase, and ELISA assay. SEM and TEM tool were used to follow the morphological changes occurred on the cell surface.

Abstract
Pyrazole derivatives are known to be as non-steroidal anti-inflammatory drugs (NSAID). Celecoxib is the pioneer sulfonamide being pyrazole derivative COX-2 inhibitors, which used to treat pain and inflammation; they may also have a role in cancer prevention. In the present investigation, a series of arylidene analogues (NDP-4011 to NDP-4016) were synthesized by the condensation of 4-(3-methyl-5-oxo-4,5-dihydro-1H-pyrazol-1-yl) benzenesulfonamide (I) with various substituted aromatic aldehydes in ethanol using a catalytic amount of piperidine. All the synthesized compounds were well characterized by IR, 1H NMR, 13C NMR and mass spectrometry. The cytotoxicity of synthesized compounds was tested on the NRK-52E cell line. From which NDP-4011, NDP-4012, NDP-4013, NDP-1015 and NDP-4016 were found to have higher cytotoxicity whereas NDP-4014 showed less cytotoxicity compared to Celecoxib. The in silico pharmacokinetic parameters of compounds were evaluated to check their candidature as a drug. Molecular docking was carried out on COX-2 structures, which revealed that NDP-4011 to NDP-4016 targets allosteric binding site similar to the binding mode of the selective COX inhibitor Celecoxib. Furthermore, results of in vitro COX-2 inhibition assay supports arylidene analogues as COX-2 inhibitors.

The development of multidrug resistance in the malarial parasite has sabotaged majority of the eradication efforts by restraining the inhibition profile of first line as well as second line antimalarial drugs, thus necessitating the development of novel pharmaceutics constructed on appropriate scaffolds with superior potency against the drug-resistant and drug-susceptible Plasmodium parasite. Over the past decades, the infectious malarial parasite has developed resistance against most of the contemporary therapeutics, thus necessitating the rational development of novel approaches principally focused on MDR malaria. This review presents an epigrammatic collation of the epidemiology and the contemporary antimalarial therapeutics based on the 'azole' motif.

Abstract
Background:
This paper describes the synthesis of novel thiazolidin-4-one substituted
pyrazole derivatives from the condensation reaction of hydrazide with acetophenone derivatives.
Herein we describe the synthesis of fourteen compounds by microwave irradiation method. The synthesized
compounds are in excellent yield by utilizing microwave irradiation heating.
Objective:
Compounds using different aromatic or heteroaromatic compounds should be synthesized
and screened for their antibacterial activity to explore the possibility of pyrazole substituted thiazolidin-
4-ones as a novel series of antimicrobials.
Method:
Synthesis of thiazolidin-4-one substituted pyrazole derivatives was carried out under microwave
radiation.
Result:
These compounds were identified on the basis of melting point range, Rf values, IR, 1HNMR
and mass spectral analysis. These compounds were evaluated for their in vitro antimicrobial
activity and their Minimum Inhibitory Concentration (MIC) was determined. Among them Comp. 4b
and Comp. 4k possess appreciable antimicrobial and antifungal activities.
Conclusion:
A novel series of Thiazolidin-4-one substituted pyrazole were synthesized under microwave
irradiation method and identified on the basis of melting point range, Rf values, IR, 1HNMR,
mass spectral data and elemental analysis. The compounds were subjected to in vitro antimicrobial
screening and their Minimum Inhibitory Concentrations (MIC) were determined. Among all
the tested compounds, two compounds 4b and 4k exhibited moderate to significant activity against
all the tested strains of bacteria and fungus were found to have appreciable antimicrobial activities.
The results of antibacterial activity showed that compounds containing electron withdrawing groups
were found to be more active than the compounds containing electron releasing groups.

Abstract
BACKGROUND Pyrazol-5-amine derivatives are an important class of heterocyclic compounds. However, there are less 4-alkyl substituted pyrazoles reported. OBJECTIVE Here reported are the design, synthesis and biological evaluation of 3-aryl-4- alkylpyrazol-5-amines derivatives. METHODS A serials of 3-aryl-4-alkylpyrazol-5-amines were designed and the biological action targets were screened by target fishing function of Discovery Studio software. The synthesis route involved 3-oxo-3-arylpropanenitrile formation, alkylation, pyrazole formation, and amides formation. The antitumor activities of these compounds were carried out by thiazolyl blue tetrazolium bromide (MTT) method using U-2 OS (osteosarcoma) and A549 (lung cancer) tumor cells. RESULTS Eight 3-aryl-4-alkylpyrazol-5-amines were synthesized, and their structures were verified by 1H NMR, 13C NMR, and HRMS. Thirteen pharmacophores were mapped out by target fishing. Compound 5h showed anti-proliferation activities against U-2 OS and A549 tumor cell with IC50 value of 0.9 μM and 1.2 μM, respectively. CONCLUSION Compound 5h might represent a promising scaffold for the further development of novel antitumor drugs.

Abstract
Aim: Novel open chain and cyclized derivatives containing pyrazole scaffold were designed, synthesized and evaluated as antileishmanial compounds. Methodology & results: In silico reverse docking experiment suggested Leishmania major pteridine reductase (Lm-PTR1) as a putative target for the synthesized compounds. In vitro antileishmanial screening against L. major promastigotes and amastigotes using miltefosine and amphotericin B as references showed that the majority of the compounds displayed activity higher than miltefosine. Compounds 3i and 5 showed the highest antileishmanial activity with IC50 values of 1.45 ± 0.08 μM and 2.30 ± 0.09 μM, respectively, for the amastigote form. In silico drug-likeness and toxicity predictions showed acceptable profiles for most of the compounds, which were validated by experimental toxicity studies. Conclusion: This study offers promising entities for antileishmanial activity.

Abstract
A library of short di-, tri-, and tetra-peptides with an s-triazine moiety at the N terminus and either an amide or ethyl ester C terminus was prepared in solution and on the solid phase. The two remaining positions of the s-triazine moiety were substituted with methoxy, morpholino, or piperidino groups. All the synthesized peptide derivatives were analyzed by HPLC and fully characterized by IR spectroscopy, 1 H and 13 C NMR spectroscopy, elemental analysis, and mass spectrometry (MALDI TOF/TOF). A preliminary study of the antileishmanial activity of the 1,3,5-triazinyl peptide derivatives revealed that four dipeptide amide derivatives showed higher antipromastigote or antiamastigote activity than the reference standard drug miltefosine with no significance acute toxicity.

Abstract
Depravity of malaria in terms of morbidity and mortality in human beings makes it a major health issue in tropical and subtropical areas of the globe. Drug counterfeiting and non-adherence to the treatment regimen have significantly contributed to development and spread of multidrug resistance that has highlighted the need for development of novel and more efficient antimalarial drugs. Complexity associated with cancer disease and prevalence of diversified cell populations vindicates highly specific treatment options for treatment of cancer. Resistance to these anticancer agents has posed a great hindrance in successful treatment of cancer. Pondering this ongoing situation, it was speculated to develop novel compounds targeting malaria and cancer. Moving on the same aisle, we synthesized pyrazole acrylic acid based oxadiazole and amide derivatives using multi-step reaction pathways (6a-x; 6a'-h'). Schizont maturation inhibition assay was employed to determine antimalarial potential. Compound 6v emerged as the most potent antimalarial agent targeting falcipain-2 enzyme. Anticancer activity was done using sulforhodamine B assay. Compounds 6b' and 6g' demonstrated promising results against all the tested cell lines. Further, Microscopic view clearly indicated formation of apoptotic bodies, chromatin condensation, shrinkage of cells and bleb formation. Validation of the results was achieved using molecular docking studies. From the obtained results, it was observed that cyclization (oxadiazole) favored antimalarial activity while non-cyclized compounds (amides) emerged as better anticancer agents.

Abstract
BACKGROUND Acyl hydrazones are an important class of heterocyclic compounds promising pharmacological characteristics. Malaria is a life-threatening mosquito-borne blood disease caused by a plasmodium parasite. In some places, malaria can be treated and controlled with early diagnosis. However, some countries lack the resources to do this effectively. RESULTS The present work involves the design and synthesis of some novel acyl hydrazone based molecular hybrids of 1,4-dihydropyridine and pyrazole (5a-g). These molecular hybrids were synthesised by condensation of 1,4-dihydropyridin-4-yl-phenoxyacetohydrazides with differently substituted pyrazole carbaldehyde. The final compound (5) showed two conformations (the major, E, s-cis and the minor, E, s-trans) as revealed by NMR spectral data and further supported by the energy calculations (MOPAC2016 using PM7 method). All the synthesised compounds were screened for their in vitro antimalarial activities against chloroquine-sensitive malaria parasite Plasmodium falciparum (3D7) and antimicrobial activity against Gram positive bacteria i.e. Bacillus cereus, Gram negative bacteria i.e. Escherichia coli and antifungal activity against one fungus i.e. Aspergillus niger [corrected]. All these compounds were found more potent than chloroquine and clotrimazole, the standard drugs. CONCLUSIONS In vitro antiplasmodial IC50 value of the most potent compound 5d was found to be 4.40 nM which is even less than all the three reference drugs chloroquine (18.7 nM), pyrimethamine (11 nM) and artimisinin (6 nM). In silico binding study of compound 5d with plasmodial cysteine protease falcipain-2 indicated the inhibition of falcipain-2 as the probable reason for the antimalarial potency of compound 5d. All the compounds had shown good to excellent antimicrobial and antifungal activities.

Abstract
Aim: A new series of pyrazolo[1,5-c]pyrimidines were synthesized by different hybridization strategies. Methodology: All structures were confirmed by IR, 1H, 13C, 1H-13C heteronuclear multiple-quantum correlation (HMQC) spectra and microanalysis. They were evaluated for their in vitro antileishmanial activity against miltefosine and amphotericin B deoxycholate as reference drugs. Results: The most active compounds 2a and 9a demonstrated superior potencies to miltefosine by ten- and six-fold, respectively, for the promastigote form, and by 5.5-fold for the amastigote form. Their binding scenario to Leishmania major pteridine reductase was rationalized by docking experiments. In addition, all compounds were safe for the experimental animals orally up to 150 mg/kg and parenterally up to 75 mg/kg. Conclusion: This study provides novel chemotype class for antileishmanial activity. [Formula: see text]

Abstract
An efficient synthesis of 10 4,4′-(arylmethylene)bis(3-carboxymethyl-1-phenyl-1 H-pyrazol-5-ol)s, eight of which are novel, was achieved by a one-pot three-component reaction of phenylhydrazine, dimethyl acetylenedicarboxylate and an arylaldehyde using bis(1(3-methoxysilylpropyl)-3-methyl-imidazolium) copper tetrachloride tethered to colloidal silica nanoparticles as catalyst under microwave irradiation in water. The advantages of the present process are atom economy, high catalytic activity, excellent yields, short reaction times and utilisation of microwave heating as a clean procedure. The catalyst was recyclable.

Abstract
Synthesis of pyrazole-linked triazolo-pyrimidine hybrids was achieved by employing Biginelli-type reaction methodology in an ionic liquid (triethylammonium acetate) under microwave irradiation. This method proved to be highly efficient and the ionic liquid employed was found recyclable for up to five consecutive cycles. The synthesized molecules were further screened for their antimalarial efficacy screening out the active scaffolds J15, J18, J21, J24, J27, and J30. The active molecules were evaluated in an enzyme inhibition study against the active Plasmodium falciparum dihydrofolate reductase (Pf-DHFR), computationally as well as in vitro, demonstrating their potency as DHFR inhibitors. The active entities were also investigated for their oral bioavailability by predicting ADME properties in silico, indicating good bioavailability.

Abstract
By using molecular docking studies, the practice of fragment based drug discovery is conceptualized by introducing oxindole and iso-propanol moieties in our previous lead molecule 1. The resulting compound 2 exhibited competitive inhibition and favorable Ka and Ki for hDHFR. The screening of compound 2 at 60 cell line panel of human tumor cell lines showed its considerably better efficacy than compound 1 and hence put the candidature of 2 on stronghold for further studies.

Abstract
From reactions of arylhydrazines with R2COCH2CONHPh or R2COCH2CO2Me, different tautomeric pyrazolinone forms, 1-aryl-3-R2-4,5-dihydro-1H-pyrazol-5-ones (IIa), 1-aryl-3-R2-1H-pyrazol-5-ols (IIb) and 2-aryl-5-R2-1,2-dihydro-3H-pyrazol-3-ones (IIc)], can be isolated. The crystal structures of monoclinic- and triclinic-3-phenyl-1-(3-nitrophenyl)-4,5-dihydro-1H-pyrazol-5-one (IIa forms), tautomeric 1-(4-methylphenyl)-3-phenyl-4,5-dihydro-1H-pyrazol-5-one (IIa form), and 1-(4-methylphenyl)-3-phenyl-1H-pyrazol-5-ol (IIb form), as well as1-(4-methoxyphenyl)-3-phenyl-1H-pyrazo-5-ol (IIb form) and 2-(4-methoxyphenyl)-5-methyl-1,2-dihydro-3H-pyrazol-3-one (IIc form) are reported.
The data suggest thatthe most electron withdrawing aryl group [3-nitrophenyl] generates IIa forms, while the most electron releasing aryl group [4-methoxyphenyl] generates IIb and IIc forms and that the aryl group with the intermediate electronic effect [4-methylphenyl] provides both IIa and IIb forms. This trend is supported by the reported isolations of 1-(4-chlorophenyl)-3-phenyl-4,5-dihydro-1H-pyrazol-5-one and 1-(2,4-nitrophenyl)-3-methyl-4,5-dihydro-1H-pyrazol-5-one [both IIa-forms] with electron-withdrawing chloro and nitro groups respectively and by the isolation of IIb and co-crystallised IIb/IIc forms from use of phenylhydrazine as the reactant.

Abstract
In the title compound, C24H26N4O2, the complete molecule is generated by the application of twofold symmetry. The pyrazole ring is approximately planar [r.m.s. deviation = 0.026 Å] and the benzene ring is twisted out of this plane [dihedral angle = 21.94 (7)°]. A twist in the molecule about the central C—C bond [1.566 (3) Å] is also evident [C—C—C—C torsion angle = 44.30 (14)°]. Supramolecular layers in the bc plane are formed in the crystal packing via C—H⋯O and C—H⋯π interactions.

Abstract
In the title pyrazole derivative, C11H11N3O2, the benzene ring is twisted [dihedral angle = 31.38 (12)°] with respect to the pyrazole ring (r.m.s. deviation = 0.009 Å). The nitro group is effectively coplanar with the benzene ring to which it is attached [O—N—C—C torsion angle = −6.5 (3)°]. Supramolecular chains along the b axis are formed owing to π–π interactions [3.8653 (2) Å] between translationally related molecules involving both the five- and six-membered rings.

Abstract
In the title pyrazolone derivative, C15H12N2O, the five-membered ring is approximately planar (r.m.s. deviation = 0.018 Å), and the N- and C-bound benzene rings are inclined to this plane [dihedral angles = 21.45 (10) and 6.96 (10)°, respectively] and form a dihedral angle of 20.42 (10)° with each other. Supramolecular layers are formed in the crystal structure via C—H⋯O and C—H⋯N interactions, and these are assembled into double layers by C—H⋯π and π–π interactions between the pyrazole and C-bound benzene rings [ring centroid–centroid distance = 3.6476 (12) Å]. The double layers stack along the a axis being connected by π–π interactions between the N- and C-bound benzene rings [ring centroid–centroid distance = 3.7718 (12) Å].
