“…The compound was also docked against three proteins encoded by protooncogenes: tyrosine protein kinase ABL (PDB ID: 1IEP), tyrosine-protein kinase c-Src (PDB ID: 2SRC), and fmslike tyrosine kinase 3 (FLT3) (PDB ID: 4RT7). Inhibition of these known anticancer drug targets have been reported to either agree with in vitro cytotoxicity evaluation of compounds against K-562 or exhibit significant homology with Abl whose kinase domain mutation on chromosome 9 promotes bone marrow cell proliferation and eventually causes CML (Manetti et al 2006;Cherukupalli et al 2018;Gokhale et al 2019;Alimohammadi et al 2020). Imatinib was used as a control.…”

Tuberculosis (TB) and cancer are among the maladies with high morbidity and mortality rates to date. This prompted the utilization of natural products in the discovery and development of new anti-TB and anticancer derivatives. In this study, we explored the antitubercular and antiproliferative activities of extracts and tetrahydrobisbenzylisoquinoline alkaloids tetrandrine (1) and limacusine (2) from the Philippine medicinal plant Phaeanthus ophthalmicus. Antitubercular evaluation using colorimetric MABA (microplate Alamar blue assay) assays revealed antitubercular activities of the extracts and fractions [minimum inhibitory concentration (MIC) = 15.6 to < 64 μg/mL]. Among the two isolated alkaloids, limacusine (2) exhibited inhibitory activity against Mycobacterium tuberculosis (MIC = 42.6 μg/ml). In addition, CellTiter-Blue cell viability assay showed antiproliferative activity for limacusine (2) against K-562. Both tetrahydrobisbenzylisoquinoline alkaloids exhibited cytotoxicity on HeLa cells. To probe the binding mechanisms of 1 and 2 against putative protein targets, molecular docking simulations were carried out. Limacusine (2) showed high binding propensities to mycobacterial enzymes ATP-dependent murE ligase and enoyl acyl carrier protein reductase, thus illustrating possibilities of cell wall and mycolic biosynthesis inhibitory mechanisms, respectively. High binding affinity was also observed in 2 vs. FLT3, a protein target implicated in myeloid leukemia cell proliferation. Additionally, the limacusine-InhA and limacusine-FLT3 complexes were found to be dynamically stable as per molecular dynamics (MD) simulations. The results of in vitro

“…Besides the known anticancer activity of aminoaryl-based 1,4 naphthoquinones (examples of which have already been discussed in some hybridization protocols), Alimohammadi et al [ 39 ] regarded the diaminodiphenyl sulfone structure of dapsone, a synthetic compound with antibacterial and antifungal activities, also used as pharmacophore in the design of anticancer agents. The N -methyl piperazine 25 ( Figure 9 ) showed the highest activity against human leukemia cell line, and was shown to be more effective than dapsone against the S. epidermidis bacterium.…”

In recent decades, molecular hybridization has proven to be an efficient tool for obtaining new synthetic molecules to treat different diseases. Based on the core idea of covalently combining at least two pharmacophore fragments present in different drugs and/or bioactive molecules, the new hybrids have shown advantages when compared with the compounds of origin. Hybridization could be successfully applied to anticancer drug discovery, where efforts are underway to develop novel therapeutics which are safer and more effective than those currently in use. Molecules presenting naphthoquinone moieties are involved in redox processes and in other molecular mechanisms affecting cancer cells. Naphthoquinones have been shown to inhibit cancer cell growth and are considered privileged structures and useful templates in the design of hybrids. The present work aims at summarizing the current knowledge on antitumor hybrids built using 1,4- and 1,2-naphthoquinone (present in natural compounds as lawsone, napabucasin, plumbagin, lapachol, α-lapachone, and β -lapachone), and the related quinolone- and isoquinolinedione scaffolds reported in the literature up to 2021. In detail, the design and synthetic approaches adopted to produce the reported compounds are highlighted, the structural fragments considered in hybridization and their biological activities are described, and the structure–activity relationships and the computational analyses applied are underlined.

Inhibition studies of enzymes in the pentose phosphate pathway (PPP) have recently emerged as a promising technique for pharmacological intervention in several illnesses. Glucose 6-phosphate dehydrogenase (G6PD) and 6-phosphogluconate dehydrogenase (6PGD) are the most important enzymes of the PPP. For this purpose, in the current study, we examined the effect of some fluorophenylthiourea on G6PD and 6PGD enzyme activity. These compounds exhibited moderate inhibitory activity against G6PD and 6PGD with K I values ranging from 21.60 ± 8.42 to 39.70 ± 11.26 μM, and 15.82 ± 1.54 to 29.97 ± 5.72 μM, respectively.2,6-difluorophenylthiourea displayed the most potent inhibitory effect for G6PD, and 2-fluorophenylthiourea demonstrated the most substantial inhibitory effect for 6PGD. Furthermore, the molecular docking analyses of the fluorophenylthioureas, competitive inhibitors, were performed to understand the binding interactions at the enzymes' binding site.6-phosphogluconate dehydrogenase, fluorophenylthiourea, glucose 6-phosphate dehydrogenase, molecular docking | INTRODUCTIONOne of the main intracellular reducing agents, nicotinamide adenine dinucleotide phosphate (NADPH), is mainly produced by the pentose phosphate pathway (PPP) and is crucial for the thioredoxin and glutathione systems. 1-4 PPP is the main pathway for glucose catabolism and the biosynthesis of aromatic amino acids, nucleic acids, glucose 6-phosphate dehydrogenase (G6PD), and 6-phosphogluconate dehydrogenase (6PGD) enzymes. These enzymes are the most important enzymes of the PPP play an essential role in the formation of NADPH. [5][6][7][8] On the other hand, an activated PPP affects tumor metabolism, such as angiogenesis, favoring tumor metastasis, promoting malignant transformation, protecting cells from apoptosis, and increasing tumor progression. [9][10][11][12] In recent years, overexpression of PPP enzymes in many types of cancer has been the focus of interest for researchers. The mechanism of PPP enzymes associated with cancer progression is still under investigation. The research found that 6PGD was regulated in many types of cancer, such as colon, leukemia, breast, ovarian, liver, and thyroid. [13][14][15] Thiourea structures have several biological activities, like anticancer and antibacterial activities, and especially on the central nervous system of rodents, they have a high impact. [16][17][18] The thiourea skeleton has an essential role in pharmaceutical chemistry. Studies have shown solid cytotoxic activity against cancer cells. [19][20][21] The desired inhibitory activity of these drugs against various inhibitors is crucial in the death of cancer cells. Recently, evaluation of novel derivatives of thiourea as anti-angiogenic and antitumor agents has been published. [22][23][24]
