Inflammation is a dysregulated immune response characterized by an excessive release of proinflammatory mediators, such as cytokines and prostanoids, leading to tissue damage and various pathological conditions. Natural compounds, notably phenolic acid phytocompounds from plants, have recently garnered substantial interest as potential therapeutic agents to bolster well-being and combat inflammation recently. Based on previous research, the precise molecular mechanism underlying the anti-inflammatory activity of phenolic acids remains elusive. Therefore, this study aimed to predict the molecular mechanisms underpinning the anti-inflammatory properties of selected phenolic acid phytocompounds through comprehensive network pharmacology, molecular docking, and dynamic simulations. Network pharmacology analysis successfully identified TNF-α convertase as a potential target for anti-inflammatory purposes. Among tested compounds, chlorogenic acid (-6.90 kcal/mol), rosmarinic acid (-6.82 kcal/mol), and ellagic acid (-5.46 kcal/mol) exhibited the strongest binding affinity toward TNF-α convertase. Furthermore, phenolic acid compounds demonstrated molecular binding poses similar to those of the native ligand, indicating their potential as inhibitors of TNF-α convertase. This study provides valuable insights into the molecular mechanisms that drive the anti-inflammatory effects of phenolic compounds, particularly through the suppression of TNF-α production via TNF-α convertase inhibition, thus reinforcing their anti-inflammatory attributes.

Chemical conversion of the extract of natural resources is a very attractive way to expand the chemical space to discover bioactive compounds. In order to search for new medicines to treat parasitic diseases that cause high morbidity and mortality in affected countries in the world, the ethyl acetate extract from the rhizome of Alpinia galanga (L.) has been chemically converted by epoxidation using dioxirane generated in situ. The biological activity of chemically converted extract (CCE) of A. galanga (L.) significantly increased the activity against Leishmania major up to 82.6 ± 6.2 % at 25 μg/mL (whereas 2.7 ± 0.8% for the original extract). By bioassay-guided fractionation, new phenylpropanoids (1–6) and four known compounds, hydroquinone (7), 4-hydroxy(4-hydroxyphenyl)methoxy)benzaldehyde (8), isocoumarin cis 4-hydroxymelein (9), and (2S,3S,6R,7R,9S,10S)-humulene triepoxide (10) were isolated from CCE. The structures of isolated compounds were determined by spectroscopic analyses of 1D and 2D NMR, IR, and MS spectra. The most active compound was hydroquinone (7) with IC₅₀ = 0.37 ± 1.37 μg/mL as a substantial active principle of CCE. In addition, the new phenylpropanoid 2 (IC₅₀ = 27.8 ± 0.34 μg/mL) also showed significant activity against L. major compared to the positive control miltefosine (IC₅₀ = 7.47 ± 0.3 μg/mL). The activities of the isolated compounds were also evaluated against Plasmodium falciparum, Trypanosoma brucei gambisense and Trypanosoma brucei rhodeisense. Interestingly, compound 2 was selectively active against trypanosomes with potent activity. To the best of our knowledge, this is the first report on the bioactive “unnatural” natural products from the crude extract of A. galanga (L.) by chemical conversion and on its activities against causal pathogens of leishmaniasis, trypanosomiasis, and malaria.

Antibiotic and antifungal resistance problems have been prevalent in recent decades. One of the efforts to solve the problems is to develop new medicines with more potent antibacterial and antifungal activity. N-phenylbenzamides have the potential to be developed as antibacterial and antifungal medicine. This study aimed to synthesize N-phenylbenzamides and evaluate their in silico and in vitro antibacterial and antifungal activities. The in silico studies conducted absorption, distribution, metabolism, excretion and toxicity (ADMET) predictions along with molecular docking studies. ADMET predictions used pkCSM software online, while the docking studies used MVD software (Molegro ^® Virtual Docker version 5.5) on Aminoglycosid-2 ″-phosphotransferase-IIa (APH2 ″-IIa) enzyme with protein data bank (PDB) ID code 3HAV as antibacterial and aspartic proteinases enzyme (Saps) with PDB ID code 2QZX as an antifungal. In vitro, antibacterial and antifungal tests were carried out using the zone of inhibition (ZOI) method. The five N-phenylbenzamides (3a–e) were successfully synthesized with a high yield. Based on in silico and in vitro studies, compounds 3a–e have antibacterial and antifungal activities, where they can inhibit the growth of Gram-positive bacteria (Staphylococcus aureus), Gram-negative (Escherichia coli), and Candida albicans. Therefore, compounds 3a–e can be developed as a topical antibacterial and antifungal agent.

Objectives: This study aims to synthesize a series of benzoxazines ( 1 – 5 ) to be examined as an epidermal growth factor receptor (EGFR) inhibitor by in-silico study. The overexpression of EGFR causes the growth of normal lung cells to become uncontrollable, which may lead to cancer formation. We also conducted the absorption, distribution, metabolism, excretions and toxicity (ADMET) properties evaluation and also examined in vitro anticancer assay on human lung cancer cells line, which is A549. Methods: Benzoxazines ( 1 – 5 ) were synthesized by reacting anthranilic acid and benzoyl chlorides. The structures of the compounds were determined with ¹ H, ¹³ C-NMR, HRMS, UV and FT-IR spectrometric methods. Prediction of ADMET was using online pkCSM, and the molecular docking studies were using MVD with EGFR-TKIs as the target (PDB ID: 1M17). In vitro assay of anticancer activity was performed by MTT assay. Results: Compounds 1 – 5 were successfully synthesized in good yields (71–84%). The ADMET prediction showed that benzoxazines are able to be absorbed through GIT, metabolized by CYP 450, and not hepatotoxic. The title compounds have a greater Moldock Score than Erlotinib, and 3 has the highest activity against A549 compared with other benzoxazines, IC ₅₀ =36.6 μg/mL. Conclusions: Compound ( 3 ) more active as anticancer against Human cancer cells line compared with other benzoxazines.

This study aims to discover the immunomodulatory potential of the ethanol extract (EE) and the ethyl acetate fraction (EAF) of Curcuma heyneana Valeton and Zijp (Indonesian name: temu giring) rhizome using mice models. The affinity of the curcuminoid (curcumin, dimethoxy-, and bisdemethoxy-) through the Transient Receptor Potential Vanilloid 1 (TRPV1) was determined using Mollegro molecular docking in silico. The curcuminoid concentration of the EE and EAF of C. heyneana rhizome were determined using thin-layer chromatography densitometry. In vivo studies in mice models were conducted using the carbon clearance method to determine the phagocytosis index, and the number of leukocytes in the blood and spleen. Forty mice were divided into eight groups, including negative control (given 1% CMC-Na), positive control (given Stimuno Forte® suspension at a dose of 6.5 mg/kg BW), three groups given the EAF of C. heyneana rhizome extract at a dose of 125 mg/kg BW, 250 mg/kg BW, and 500 mg/kg BW, respectively, and three groups were given EE of temu giring rhizome extract with doses of 125 mg/kg BW, 250 mg/kg BW, and 500 mg/kg BW, respectively. E.E. and E.A.F. of C. heyneana (temu giring) rhizome extract contained dimethoxy curcumin (0.176 ± 0.01 and 4.53 ± 0.02 %b/b) greater than another curcuminoid, bisdemetoxy curcumin and curcumin. EE at 125 mg/kg BW and EAF dose at 500 mg/kg B W. of temu giring rhizome have immunostimulant activity with a phagocytosis index value of >1 compared to the negative control (p < 0.05). Additionally, both increase the number of lymphocytes, monocytes, and neutrophil cells in peripheral blood and spleen compared to the negative control (p < 0.05). Their activity was seen as similar to the positive control. Therefore, the EE of C. heyneana rhizome has immunostimulant activity, and the EAF of C. heyneana rhizome has immunosuppressant activity at 125 mg/kg BW and immunostimulant at a higher dose. The activity of temu giring as an immunomodulator was associataed with its affinity to TRPV1.
