[PMID: 38398601 PMCID: PMC10893115 DOI: 10.3390/molecules29040849] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2023] [Revised: 01/29/2024] [Accepted: 01/30/2024] [Indexed: 02/25/2024] Open
Abstract
Compounds derived from natural sources continue to serve as chemical scaffolds for designing prophylactic/therapeutic options for human healthcare. In this study, we aimed to systematically unravel the chemical profile and antioxidant and anti-inflammatory activities of myrtle methanolic extract (MMEx) using in vitro, in vivo, and in silico approaches. High levels of TPC (415.85 ± 15.52 mg GAE/g) and TFC (285.80 ± 1.64 mg QE/g) were observed. Mass spectrophotometry (GC-MS) analysis revealed the presence of 1,8-cineole (33.80%), α-pinene (10.06%), linalool (4.83%), p-dimethylaminobenzophenone (4.21%), thunbergol (4%), terpineol (3.60%), cis-geranyl acetate (3.25%), and totarol (3.30%) as major compounds. MMEx induced pronounced dose-dependent inhibition in all assays, and the best antioxidant activity was found with H2O2, with an IC50 of 17.81 ± 3.67 µg.mL-1. MMEx showed a good anti-inflammatory effect in vivo by limiting the development of carrageenan-induced paw edema. The pharmacokinetic profiles of the active molecules were determined using the SwissADME website, followed by virtual screening against anti-inflammatory targets including phospholipase A2 (PLA-2), cyclooxygenase-2 (COX-2), tumor necrosis factor alpha (TNF-α), interleukin-1β (IL-1β), and NF-κB. A pharmacokinetic study revealed that the molecules have good absorption, distribution, and metabolism profiles, with negative organ toxicity. Among the compounds identified by GC-MS analysis, pinostrobin chalcone, cinnamyl cinnamate, hedycaryol, totarol, and p-dimethylaminobenzophenone were observed to have good binding scores, thus appreciable anti-inflammatory potential. Our study reveals that MMEx from Algerian Myrtus communis L. can be considered to be a promising candidate for alleviating many health complaints associated with oxidative stress and inflammation.

Abstract
The rationale at the basis of targeted approach in oncology is radically shifting-from development of highly specific agents aiming at a single target towards molecules interfering with multiple targets. This study was performed to isolate and characterize bioactive molecules from Olax subscorpioidea stem and investigate their potentials as multi-targeted inhibitors against selected non-small cell lung cancer, breast cancer and chronic myelogenous leukemia oncogenic targets. Three compounds: β-sitosterol (1), α-amyrin (2) and stigmasterol (3) were isolated. The structures of 1 - 3 were elucidated by analysis of their spectroscopic data (NMR, MS and IR). To the best of our knowledge, this is the first time these compounds were isolated from O. subscorpioidea stems. Furthermore, integrated analysis of MS/MS data using the Global Natural Products Social Molecular Networking (GNPS) workflow enabled dereplication and identification of 26 compounds, including alkaloids (remerine, boldine), terpenoids (3-hydroxy-11-ursen-28,13-olide, oleanolic acid), flavonoids (kaempferitrin, olax chalcone A) and saponins in O. subscorpioidea stem. Molecular docking studies revealed that some of the compounds, including olax chalcone A (-9.2 to -10.9 kcal/mol), 3-Hydroxy-11-ursen-28,13-olide (-6.6 to -10.2 kcal/mol), α-amyrin (-6.6 to -10.2 kcal/mol), stigmasterol (-7.7 to -10.1 kcal/mol), β-Sitosterol (-7 to -9.9 kcal/mol) and kaempferitrin (-7.7 to -9 kcal/mol) possessed good inhibitory potentials against selected cancer targets, when compared with reference inhibitors (-8.4 to -13.7 kcal/mol). A few of these compounds were shown to have considerable to favorable pharmacokinetic and drug-likeness properties. This study provides some rationale for the use of O. subscorpioidea in ethnomedicinal management of cancer and identifies some potential anticancer agents.Communicated by Ramaswamy H. Sarma.

Essential Oils, and Exploring Molecular Docking to Predict the Inhibitory Compounds against Cyclooxygenase-2. Pharmaceuticals (Basel) 2023; 16:1343. [PMID: 37895814 PMCID: PMC10609887 DOI: 10.3390/ph16101343] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2023] [Revised: 08/31/2023] [Accepted: 09/07/2023] [Indexed: 10/29/2023] Open
Abstract
Considering the large spectrum of side effects caused by synthetic drugs and the development of natural alternatives utilizing Algerian flora, this study aimed to place a spotlight on the chemical profile and antioxidant and anti-inflammatory activities of Myrtus communis L. essential oils (MCEOs). In this study, essential oils (EOs) were collected via hydro-distillation of the plant's leaves, and a chemical constituent analysis was performed using gas chromatography-mass spectrophotometry (GC-MS). The in vitro antioxidant activity was evaluated using DPPH, ABTS, and hydroxyl radical scavenging tests. The in vitro anti-inflammatory capacity was estimated by studying the antidenaturation effect using bovine serum albumin (BSA) as a protein model. The in vivo anti-inflammatory activity was carried out by utilizing the classical model of carrageenan-induced paw edema in rats, using diclofenac (DCF) as the reference drug. Moreover, the molecular interaction of the compounds obtained from the GC-MS analysis was studied within the binding site of cyclooxygenase-2 (COX-2) using an in silico approach as the confirmatory tool of the in vitro and in vivo experiments. The GC-MS analysis revealed that MCEOs were mainly composed of oxygenated monoterpenes (70.56%), oxygenated sesquiterpenes (3.1%), sesquiterpenes (4.17%), and monoterpenes (8.75%). Furthermore, 1,8-cineole was the major compound (19.05%), followed by cis-geranyl acetate (11.74%), methyl eugenol (5.58%), α-terpineol (4.62%), and β-myrcene (4.40%). MCEOs exhibited remarkable concentration-dependent free radical scavenging activity, with an IC50 of 15.317 ± 0.340 µg/mL, 18.890 ± 2.190 µg/mL, and 31.877 ± 0.742 µg/mL for DPPH, ABTS, and hydroxyl radical, respectively. The significant in vitro anti-inflammatory activity due to the inhibition of BSA denaturation was proportional to the EO concentration, where the highest value was recorded at 100 μg/mL with an approximately 63.35% percentage inhibition and an IC50 of 60.351 ± 5.832 μg/mL. MCEOs showed a good in vivo anti-inflammatory effect by limiting the development of carrageenan-induced paw thickness. The in silico study indicated that, among the 60 compounds identified by the GC-MS analysis, 9 compounds were observed to have a high binding energy to cyclooxygenase-2 as compared to diclofenac. Our study revealed that EOs from Algerian Myrtus communis L. can be considered to be a promising candidate for alleviating many debilitating health problems and may provide new insights in the fields of drug design, agriculture, and the food industry.

Abstract
Abrus precatorius L. is a traditional remedy with a long history of use in medicine around the globe due to its diverse phytochemical composition and bioactivities which are of utmost significance to the scientific community. With the aim to provide new insights into the antioxidant, antiproliferative and antiangiogenic properties of A. precatorius aqueous seed extracts, different extraction methods were employed. Aqueous extract prepared by Soxhlet method APW (Sox) had higher total phenolics, flavonoids and tannin content. In DPPH assay, APW (Sox) had the maximum free radical scavenging activity. The maximum FRAP value was displayed by APW (Mac). The maximum inhibition was shown by APW (Sox) against HPV18 (Hep2C) cells and APW (Mac) against HPV18 (KB) cells. In cervical cancer (Hep2C) cells, catalase (CAT), glutathione-s-transferase (GST) activity, and glutathione (GSH) content were all highest in APW (Sox) extract, whereas APW (Mac) extract demonstrated the highest superoxide dismutase (SOD) activity and the lowest malondialdehyde (MDA) content. Similarly, in oral cancer (KB) cells, APW (Mac) extract showed the highest SOD, CAT, GST activity and GSH content whereas APW (Sox) extract showed the least MDA content. Docking studies showed that tannic acid and rutin had the highest binding affinity, while MD simulations showed that they were stable in complex with COX-2 for at least 90 ns. Promising antiangiogenic activities were observed in both APW (Sox) and APW (Mac) in a dose dependent manner. Therefore, aqueous seed extracts of A. precatorius could be considered promising candidates for anticancer and antiangiogenic drugs.Communicated by Ramaswamy H. Sarma.

Abstract
Abrus precatorius (Jequirity, Indian liquorice, rosary bead, Gunja, or rati) seeds are highly toxic and are often ingested as a means of suicide in India. Gastric symptoms like bleeding, diarrhea, vomiting, and epigastric pain are the common manifestations of this toxicity. Abrin, a toxic substance found in the seeds, is structurally and functionally similar to ricin and is considered even more fatal. We report the first case of Abrus precatorius poisoning, where the internet was utilized to procure a potentially deadly poison with the intention to commit suicide in north India. Such actions are relevant to the medical field, particularly regarding the potential risks associated with the unsupervised procurement and misuse of toxic substances. The case highlights the potentially fatal consequences of ingesting Abrus seeds and the need for prompt medical attention in such cases.

Abstract
Breast cancer remains a major world health challenge in women. Some Breast cancers are human epidermal growth factor receptor 2 (HER2) positive. Since this protein promotes the growth of cancer cells, it remains a therapeutic target for novel drugs. This study uses in silico model to predict HER2 inhibitors from curcumin derivatives via QSAR, e-pharmacophore, ADMET as well as structure-based virtual screening using Schrodinger suite. The molecular dynamics simulation of lead compounds, reference ligand and co-crystalized ligand was performed using GROMACS. At the end, eight active curcumin derivatives were predicted as inhibitors of HER2 with high binding affinity and better interaction compared with the reference drug (Neratinib) but lower binding affinity compared with the co-crystalized ligand (TAK-285). After prediction of the bioactivity of the molecules using AutoQSAR, the hit compounds showed appreciable inhibitory pIC50 compared with the reference and co-crystalized ligands against HER2. The pharmacokinetics profile predicted the eight hit compounds as drug-like and drug candidates. The MD simulation predicted the stability of the two top-scored compounds (10763284 and 78321412) in complex with HER2 for the final 80 ns of the trajectory period after initial equilibration with higher H-bond interactions in the protein-reference drug complex compared to the hit compounds-HER2 complexes. This study revealed that curcumin derivatives especially (1E,6E)-1,8-bis(4-hydroxy-3-methoxyphenyl)octa-1,6-diene-3,5-dione and (1E,6E)-4-ethyl-1,7-bis(4-hydroxy-3-methoxyphenyl)hepta-1,6-diene-3,5-dione were identified to demonstrate inhibitory activity against HER2 which is comparable to neratinib. Conclusively, the lead compounds require further in vitro and in vivo experimental validation for the discovery of new HER2 antagonists for breast cancer management.Communicated by Ramaswamy H.
