Numerous prior studies have identified therapeutic targets that could effectively combat severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, including the angiotensin-converting enzyme 2 (ACE2) receptor, RNA-dependent RNA polymerase (RdRp), and Main protease (Mpro). In parallel, antiviral compounds like abacavir, acyclovir, adefovir, amantadine, amprenavir, darunavir, didanosine, oseltamivir, penciclovir, and tenofovir are under investigation for their potential in drug repurposing to address this infection. The aim of the study was to determine the effect of modifying the functional groups of the aforementioned antivirals in silico. Using the genetic optimization for ligand docking algorithm on software Maestro (version 11.1), the modified antivirals were docked onto ACE2 receptor, RdRp, and Mpro. Using QuickProp (Maestro v11.1), PASS (prediction of activity spectra for the substances), and altogether with SwissADME, the ADMET (absorption, distribution, metabolism, excretion, and toxicity) of the modified antivirals, as well as their bioavailability and the predicted activity spectra, were determined. Discovery studio software was used to undertake post-docking analysis. Among the 10 antivirals, N(CH3)2 derivative of darunavir, N(CH3)2 derivative of amprenavir and NCH3 derivative of darunavir exhibited best binding affinities with ACE2 receptor (docking scores: -10.333, -9.527 and -9.695 kJ/mol, respectively). Moreover, NCH3 derivative of abacavir (-6.506 kJ/mol), NO2 derivative of didanosine (-6.877 kJ/mol), NCH3 derivative of darunavir (-7.618 kJ/mol) exerted promising affinity to Mpro. In conclusion, the results of the in silico screenings can serve as a useful information for future experimental works.

The research focused on Wedelia montana (Blume) Boerl because of its numerous medicinal applications. W. montana belongs to the Asteraceae family. This investigation is intended to analyze the phytochemical content of the methanol extract of W. montana (MEWM) and evaluate its biological features by utilizing in vitro and in vivo models. In vitro examinations determined antioxidant capability, cytotoxic, anthelmintic, and thrombolytic activity of the MEWM. Furthermore, in vivo research included testing for the effects of antidepressants (TST and FST), effects on anxiety (LDT, HBT, and EPM), activities of sedatives (HCT and OFT), and analgesic activities (formalin‐induced licking test and tail immersion test). Treatment with MEWM exhibited potent antioxidant properties, with a cytotoxicity test revealing an LC ₅₀ value of 256.2 μg/mL, in contrast to 142.28 μg/mL for the positive control. It also resulted in the shortest times for paralysis and mortality at the highest dosage in the anthelmintic assay and notable thrombolytic activity ( p < 0.0001). Moreover, MEWM has shown considerable efficacy contingent upon the FST, TST, EPM, HBT, and LDT dose and sedative effects in the OFT and HCT. A 200 mg/mL dosage in the analgesic assessment had no significant impact on the tail immersion test. However, MEWM demonstrated substantial analgesic action in the formalin‐induced paw‐licking experiment ( p < 0.0001). The data indicate that MEWM is a potential source of antioxidant, cytotoxic, anthelmintic, thrombolytic, antidepressant, anxiolytic, sedative, and antinociceptive compounds. Further research is necessary to comprehend its therapeutic benefits completely.

There has been a recent rise in the utilization of complementary herbal medicines as a means to discover efficacious alternative treatments that mitigate the negative consequences of pharmaceuticals. Colocasia affinis Schott is a member of the Araceae family, with various components such as the root, fruit, and leaves utilized for medicinal purposes. This study aims to explore the in vitro phytochemical, antioxidant, antimicrobial, anti‐inflammatory, and thrombolytic properties of the ethanolic extract obtained from the leaves of C. affinis (EECA) using an experimental approach. The extract derived from EECA revealed the presence of secondary metabolites, including alkaloids, glycosides, flavonoids, tannins, steroids, saponins, carbohydrates, amides, phenols, and reducing sugars, and demonstrated remarkable antioxidant activity in the DPPH scavenging assay (IC ₅₀ = 60.36 μg/mL). Secondly, five clinical isolates of bacteria, namely, Escherichia coli, Salmonella paratyphi, Salmonella typhi, Pseudomonas aeruginosa, and Vibrio cholerae , were employed to examine the antimicrobial properties of EECA. In the context of thrombolytic activity, EECA demonstrated a noteworthy level of clot lysis (39.086 ± 0.570% and 23.111 ± 0.398%) at doses of 500 and 250 μg/mL, respectively, when compared to streptokinase. Furthermore, EECA exhibited a significant anti‐inflammatory effect, as evidenced by the inhibition of protein denaturation (60.24 ± 1.49, 43.81 ± 1.76, and 30.83 ± 2.57) across concentration ranges of 500, 250, and 125 μg/mL. The findings indicated the presence of phytochemicals and notable free radical scavenging activity. EECA exhibited a broad range of antimicrobial activity, along with notable thrombolytic and anti‐inflammatory effects. This investigation presents empirical evidence that supports the application of EECA in traditional medicine.

Cayratia trifolia is traditionally used for treating pain, inflammation, and oxidative disorders, yet comprehensive experimental and computational validation of its pharmacological potential remains limited. The aim of this study is to investigate the phytochemical profile and evaluate antioxidant, anti‐inflammatory, and analgesic activities of methanolic and n‐hexane fractions of C. trifolia leaves using integrated in vitro, in vivo, and in silico approaches. Leaves were extracted with methanol and fractionated via a modified Kupchan method. Phytochemical screening, DPPH radical scavenging, HRBC membrane stabilization, carrageenan‐induced paw edema, acetic acid‐induced writhing, and tail immersion assays were performed. In silico analysis included PASS prediction, ADME/T profiling, and molecular docking of 40 previously documented GC–MS compounds against COX‐2 (PDB: 6COX, 1CX2, 5IKR, and 1CQE) and CYP2C9 (PDB: 1OG5 and 4L7B) protein targets. Methanolic extract demonstrated potent antioxidant activity (IC ₅₀ = 2.69  μ g/mL) and 87.46% HRBC membrane stabilization. Significant anti‐inflammatory effects were observed in vivo through reduced paw edema. The n‐hexane fraction produced notable analgesic responses, inhibiting writhing by 21.84% and increasing reaction time in the tail immersion test by 59.44% ( ^∗∗∗∗ p < 0.0001). In silico analyses identified multiple bioactive compounds—especially 2‐cyclohexylethyl isobutyl ester and lup‐20(29)‐en‐3‐yl acetate—with binding affinities surpassing diclofenac, aspirin, and ascorbic acid, along with favourable ADME/T profiles. The combined experimental and computational findings indicate that C. trifolia contains phytoconstituents with strong therapeutic potential. Its methanolic fraction, supported by in silico validation, represents a promising source for developing natural antioxidant, anti‐inflammatory, and analgesic lead molecules.
