Candida albicans is a polymorphic human microflora species, which caused a candidiasis. This disease frequently occurred in immunocompromised patients with considerable medical outcomes due to the damage from its infections. Secreted Aspartic Proteinase (SAP) 4–6 regulated the virulence of C. albicans. Thus, inhibiting those protenases may useful to obtain a better prognosis. On the other hand, Cinnamomum zeylanicum reported to have anti-cadidiasis. However, the mechanism of action on the anti-cadidiasis activity remains unclear. This study will explain the possible mechanism of anti-candidiasis from the bioactives of C. zeylanicum through SAP 4–6 inhibion. A computational analysis was employed by molecular docking coupled with molecular dynamics simulation to comprehend the interaction among C. zeylanicum bioactives to SAP 4–6. Positive docking outcomes were observed, with Cinnamaldehyde, Pyrantel Hydrochloride, and Hexadecenoic Acidbecame showed promising binding affinity against SAP 4–6. However, those compounds interacted with different residues of each proteinase. Only Hexadenoic Acid bound to the catalytic residues of SAP5-6. Molecular dynamics simulated the stable binding of Hexadecenoid Acid to the SAP5-6. Not only has stable structural integrity, the binding of Hexadecenoic Acidalso showed minimum alterations on the structural stability of SAP5-6, which suggested a stable inhibitory activity. The stable binding of Hexadecenoid Acid also displayed by the prominent number of hydrogen bond and the free-binding energy simulations. In conclusion, the anti-candidiasis activity of C. zeylanicum may take place in the SAP5-6 inhibition, mainly by Hexadecenoic Acid.

The estrogen hormone dependent accounts for a major cause in the incidence of women breast cancer. Thus, their receptor, especially the estrogen receptor α (ER-α), is becoming a target in endocrine treatment. These ligand-inducible nuclear functions are regulated by an array of phytochemical and synthetic compounds, such as 17 β-estradiol and tamoxifen (4-hydroxytamoxifen [4OHT]). The Chinaberry (Melia azedarach) leaves are known naturally for relieving internal and external diseases. Previous studies revealed the potency of Melia's ethanolic extract and ethyl acetate fractions as anticancer; furthermore, this study aimed to resolve possible ER-α antagonist's mechanism and safety from M. azedarach leaves ethyl acetate fraction contents. Melia's phytochemical content was analyzed with electrospray ionization liquid chromatography-mass spectrometry, while its ER-α antagonist's potency was investigated by in silico. The computational docking was used to 3ERT (a human ER-α-4OHT binding domain complex) with Autodock Vina and related programs. The results presented Energy binding (ΔG) of Melia's quercetin 3-O-(2'',6''-digalloyl)-β-D-galactopyranoside was similar to 4OHT, and lower than its agonist 17 β-estradiol. Furthermore, the toxicity prediction of these compounds were revealed safer than 4OHT. The Melia's leaves ethyl acetate fraction, therefore, is a potential pharmacological material for further studies.

The issue of Candida albicans resistance to antifungal agents in the management of candidiasis has emerged as a significant concern, necessitating the development of novel antifungal alternatives to ensure efficacy in the treatment of candidiasis. A notable manifestation of C. albicans pathogenicity is the development of biofilms, which are facilitated by the presence of certain genes known as agglutinin-like sequence (ALS) genes, specifically ALS1 and ALS3. The utilisation of Cinnamomum zeylanicum extract as a potential alternative antifungal agent has promise in addressing fungal resistance, particularly in the context of C. albicans, for the treatment of candidiasis. Bioactive compounds such as cinnamonaldehyde, cyclopentane, eugenic acid, hexadecenoid acid and Pyrantel Hydrochloride are present in C. zeylanicum. This research investigates the mechanistic plausibility of the bioactive chemicals found in C. zeylanicum as agents for combating candidiasis. The study specifically examines the inhibitory effects of these compounds on the Agglutinin-like sequence-1 (ALS1) and ALS3 proteins. The study employs a combination of molecular docking and molecular dynamics simulations to elucidate the complex interactions between the bioactive constituents of C. zeylanicum and ALS1/ALS3 proteins. The ligand exhibited notable binding affinity towards the molecules Cinnamaldehyde, Pyrantel Hydrochloride and Hexadecenoic Acid derived from C. zeylanicum, as seen by their binding affinity values ranging from - 4.873 to -6.03 kcal/mol. This indicates their potential effectiveness in altering the activities of the target proteins. The investigation reveals distinct interaction patterns between each chemical and the proteases. Significantly, Pyrantel Hydrochloride establishes binding interactions with essential catalytic residues in both ALS1 and ALS3. The stability of the Pyrantel Hydrochloride-ALS1/ALS3 complexes is further supported by molecular dynamics simulations, which suggest that these complexes possess a strong inhibitory capacity. The preservation of protein structures appears to be minimally impacted, indicating a prolonged inhibitory effect. The effectiveness of Pyrantel Hydrochloride is emphasized by the numerous hydrogen bonds that are formed and confirmed using free-binding energy calculations. Collectively, the results highlight the plausibility of C. zeylanicum anti-candidiasis action, principally mediated through the inhibition of ALS1 and ALS3. This activity is predominantly facilitated by Pyrantel Hydrochloride. This comprehensive understanding provides a valuable foundation for the development of innovative antifungal strategies in the battle against C. albicans infections. [ABSTRACT FROM AUTHOR]

Ventilator-associated pneumonia (VAP) caused by Pseudomonas aeruginosa poses a significant clinical challenge due to its robust biofilm formation and resistance mechanisms. Chlorhexidine (CHX), an antiseptic agent, has shown potential in inhibiting biofilm formation, though its mechanism is not fully understood. To elucidate the mechanism of action and potential of chlorhexidine in mitigating biofilm formation, we conducted reverse docking analyses targeting key quorum-sensing proteins in P. aeruginosa. Protein structures of six quorum sensing and biofilm proteins were obtained from the Protein Data Bank. The structure of CHX was retrieved from PubChem and prepared for docking. Potential binding pockets in the protein structures were identified using Fpocket, and docking simulations were performed with SMINA. We generated 395 docking poses across all proteins. The highest binding affinity was observed at PslG. Additionally, CHX's high binding affinities with RhlR and LasR indicate its potential to interfere with quorum sensing pathways. CHX shows strong binding affinities to key quorum-sensing proteins, particularly PslG, RhlR, and LasR. This suggests CHX could disrupt biofilm formation and quorum sensing in P. aeruginosa.

The occurrence of antibacterial resistance has become a global concern. The results of previous studies revealed many cases of antibacterial resistance of levofloxacin in H. pylori strains originating from Indonesia. Conventional attempts to obtain new antibacterial agents usually take a long time, other efforts are needed to speed up discovery. Databases that provide the structure of DNA gyrases cannot fully provide what is needed. This study aims to obtain the three-dimensional structure of DNA gyrase of the Indonesian H. pylori strain so that it can be used to simulate the interaction process of compounds that have the potential to be anti-H. pylori through in silico studies. This study used in silico methods to predict the absorption, distribution, metabolism, excretion, and toxicology of potential compounds. The next process involves screening for drug similarity based on criteria set by Muegge, Egan, Veber, Lipinski, and Ghose. The three-dimensional structure of DNA gyrase is formed from several samples of amino acid sequences from the Indonesian gyrA and gyrB H. pylori strains. Eligible potential compounds were subjected to molecular docking studies on gyrA and gyrB to obtain the best score. The three-dimensional structure of the Indonesian gyrA and gyrB H. pylori strains has been obtained. Eugenol, cinnamaldehyde, and ethyl p-methoxycinnamate were more easily absorbed compared to curcumin and levofloxacin as controls. Curcumin and hesperidin show poor absorption and longer distribution in the gastric mucosa, thus allowing long-term interaction with H. pylori. All compounds do not inhibit cytochrome P450, can be excreted by the body, and are non-toxic. The prediction of drug similarity passes only through curcumin and ethyl p-methoxycinnamate. The results of molecular docking concluded that curcumin and hesperidin had better scores than levofloxacin. Curcumin has the most potential as an anti-H. pylori. [ABSTRACT FROM AUTHOR]

This study aims to investigate the phytochemical compounds present in the 70% ethanol extract of Arcangelesia flava stems by LC-MS/MS and to elucidate the ligand-protein interactions through in-silico studies. The extract was found to contain alkaloids, flavonoids, furanoditerpene, hydroxyquinoline, phenylpropanoid, phenol, and fatty acids. According to molecular docking of the 15 compounds analyzed by LC-MS/MS, the compounds 3-hydroxy-3',4',5'-trimethoxyflavone (ΔG=-7.72 kcal/mol), fisisaine (ΔG=-6,91 kcal/mol), and demethyleneberberine (ΔG=-6.85 kcal/mol), which demonstrated the highest affinity for binding to the protein target. In addition, active amino acids contribute to this interaction by creating strong hydrogen bonds, such as MET148, LYS 103, and THR300. Phytochemical compounds from Arcangelesia flava may serve as adjunctive therapy or a promising source of advanced structures in drug discovery for treatments targeting interleukin-1β.

Background: Clove (Eugenia caryophyllata Thunberg) and lime (Citrus aurantifolia) are medicinal plants traditionally used to treat various diseases such as gastritis. Some studies reported that cloves leaf and lime leaf extract showed a gastroprotective effect by decreasing the gastric acid secretion and increasing the gastric mucus. Aim: This study aims to investigate the anti-gastritis activity of the combination of ethanolic extract of cloves leaf and lime leaf extract in alcohol absolute-induced mice. Methods: Mice were treated with the combination extract 0.7 g/kg BW, 1.4 g/kg BW, and 2.8 g/kg BW. Famotidine was used as a positive control, and Na CMC suspension was used as a negative control. After 45 minutes of oral administration, 0.14 ml/20g BW alcohol absolute was given to all mice. All groups were sacrificed one hour later. The evaluation showed that extract combination in all doses significantly decreased ulcer index (UI) compared to a negative control group (p<0.005) in macroscopic evaluation. Results: In histopathologic evaluation, all doses significantly decreased mucosal edema and epithelial cell loss (p<0.005), but in gastric bleeding evaluation, only 0.7 and 1.4 g/kg BW doses showed a significant decrease. Conclusion: This study showed that a combination of clove and lime leaf extracts has anti-gastritis activity and could be a possible therapeutic of anti-gastritis. The most effective dose is 1.4 g/kg BW in mice which showed the lowest ulcer index and gastric mucosal edema, bleeding and epithelial cells loss reduction on histopathological observation.

Indonesia, with its biodiversity, is overgrown by various kinds of plants that have medicinal potential, including Terap (Artocarpus odoratissimus Blanco). The leaves of A. odoratissimus are empirically used by local people of Borneo Island to treat gout. The purpose of this study was to determine the antigout activity of the active compound from A. odoratissimus leaves through xanthine oxidase inhibition using the molecular docking method and to determine the ADMET properties of these compounds. Phytochemical screening showed that A. odoratissimus leaf extract contained alkaloids, flavonoids, steroids/triterpenoids, and phenolics. The results of TLC showed that A. odoratissimus leaf extract contained steroid and flavonoid compounds in the form of stigmasterol and rutin. The results of molecular docking showed that flavan-3-ol provided the lowest bond-free energy against xanthine oxidase with a ΔG value of -8.3 kcal/mol, lower than allopurinol and hypoxanthine as reference ligands. Flavan-3-ol interacts with xanthine oxidase through hydrogen bonding with amino acid residues in the form of Arginine 912 and Lysine 1045. The prediction of ADMET properties from flavan-3-ol shows that the compound can be absorbed and has good permeability. Overall, the flavan-3-ol found in A. odoratissimus leaves shows the potential to be developed as a xanthine oxidase inhibitor for use in gout therapy. [ABSTRACT FROM AUTHOR]

The estrogen hormone dependent accounts for a major cause in the incidence of women breast cancer. Thus, their receptor, especially the estrogen receptor α (ER-α), is becoming a target in endocrine treatment. These ligand-inducible nuclear functions are regulated by an array of phytochemical and synthetic compounds, such as 17 β-estradiol and tamoxifen (4-hydroxytamoxifen [4OHT]). The Chinaberry (Melia azedarach) leaves are known naturally for relieving internal and external diseases. Previous studies revealed the potency of Melia's ethanolic extract and ethyl acetate fractions as anticancer; furthermore, this study aimed to resolve possible ER-α antagonist's mechanism and safety from M. azedarach leaves ethyl acetate fraction contents. Melia's phytochemical content was analyzed with electrospray ionization liquid chromatography-mass spectrometry, while its ER-α antagonist's potency was investigated by in silico. The computational docking was used to 3ERT (a human ER-α-4OHT binding domain complex) with Autodock Vina and related programs. The results presented Energy binding (ΔG) of Melia's quercetin 3-O-(2'',6''-digalloyl)-β-D-galactopyranoside was similar to 4OHT, and lower than its agonist 17 β-estradiol. Furthermore, the toxicity prediction of these compounds were revealed safer than 4OHT. The Melia's leaves ethyl acetate fraction, therefore, is a potential pharmacological material for further studies. [ABSTRACT FROM AUTHOR]

The cytotoxic activity of flavonoid from Temu Kunci (Kaempferia pandurata) was tested by brine shrimp lethality test and cell culture of human mammary carcinoma. This compound is pinostrobin, and has antitumor activity. However, the critical biochemical target of these pinostrobin has not been identified. In our present studies, we used DNA topoisomerase I which was isolated from human tumor. This result showed that pinostrobin inhibited DNA topoisomerase I activity. Pinostrobin may be interfere with DNA breakage-reunion reaction by stabilizing a key covalent intermediate between DNA and the enzyme, resulting in the cleavage DNA. An inhibition in the activity of DNA topoisomerase I is suggesting that this could be a possible mechanism of pinostrobin from Temu Kunci for the cytotoxicity observed in cell culture of human mammary carcinoma.
