Bajakah Roots to Lipolysis Activity

Posted on | by adminKR | Leave a Comment on Bajakah Roots to Lipolysis Activity

Abstract

Modulating the nucleotide cycle signaling of phosphodiesterases (PDEs) can facilitate thermogenesis. When it comes to obesity therapy, utilizing herbs as part of non-pharmacological treatment methods is highly recommended due to the lower risks involved compared to pharmacological methods. Bajakah root, a typical plant found in West Kalimantan, also known by its Latin name, Spatholobus littoralis Hassk (S. littoralis Hassk), is currently being extensively researched. Isorhynchophylline and rhynchophylline are common alkaloids found in S. littoralis Hassk. The objective of this study was to explore the potential of these two alkaloids through an in silico approach. Chem3D Pro software was used to prepare ligands with energy conformations for accurate docking results via AutoDock Vina software. The visualization was carried out in Biovia Discovery Studio. The lowest binding energy values were obtained for the PDE4C isoform, with values of -9.14, -7.61, and -5.61 kcal/mol, respectively. The interaction between isorhynchophylline and PDE4C had the lowest binding energy. In silico studies suggest that two alkaloid components, isorhynchophylline and rhynchophylline, found in S. littoralis Hassk have the potential to increase lipolysis activity.

Biofilm Management Review

Despite numerous available agents claiming anti-biofilm properties on wounds, the substantiating evidence remains inconclusive. This study aimed to assess the immediate impact of topical wound treatments on wound biofilm and healing outcomes in acute and chronic ulcers. We comprehensively searched PubMed, ClinicalTrials.gov, and Google Scholar. In addition, eligible gray literature was incorporated. English-language randomized controlled trials (RCTs), observational, cohort, and case-control studies targeting biofilm prevention, inhibition, or elimination across diverse wound types were included. Primary outcomes included biofilm presence and elimination, supplemented by secondary outcomes encompassing reduced wound size, complete closure, and diminished infection indicators. Bacterial load reduction and biofilm presence were also assessed. Twenty-eight articles met the inclusion criteria. Various modalities were identified, including biofilm-visualization techniques, such as wound blotting and handheld autofluorescence imaging. Pooled analysis for the primary outcomes was infeasible due to limited eligible studies and data-reporting challenges. As for the secondary outcomes, the pooled analysis for complete surgical wound closure (2 RCTs, yielding n=284) and presence of surgical site infections/inflammation (2 RCTs, yielding n=284) showed no significant difference, with a log odds ratio (LOD) of 0.58 (95% confidence interval [CI]: −.33, 1.50) and LOD −0.95 (95% CI: −3.54, 1.64; τ2 = 2.32, Q = 2.71, P = .10), respectively. Our findings suggest insufficient evidence to support anti-biofilm claims of topical modalities. Clinicians’ skill appears to play a pivotal role in biofilm elimination and wound healing enhancement, with potential optimization through visual-guided techniques, such as wound blotting and autofluorescence imaging. More rigorous clinical trials are warranted to ascertain the efficacy of these techniques.

Abstract

Objective: This study aimed to investigate the combined effects of caffeine and Alpha Lipoic Acid (ALA) on oxidative stress, due to chronic hyperglycemia, in a model of diabetic rats induced with streptozotocin (STZ) (in silico and in vivo approaches).
Material and Methods: This In silico study investigated the interaction between caffeine and ALA against insulin receptors and enzymes of Glutathione Peroksidase-1 (GPx-1), with molecular docking. Male, Wistar rats were included using a quasi-experimental research design, with post-test only and a control group (in vivo). This study measured the end result of a 6-week-induction on body weight, fasting blood glucose, Malondialdehyde (MDA) and GPx-1 enzyme from 25 rats.
Results: Molecular docking found the interactions of caffeine and GPx-1 consisting of an energy bond of -5,06 kcal/mol, hydrogen and hydrophobic bond. Additionally, it showed the interaction of ALA and
GPx-1 containing an energy bond of -5.16 kcal/mol, hydrogen bonding and hydrophobicity. However, there were
no significant difference in body weight, fasting blood glucose, MDA and GPx-1 levels of the ALA-caffeinated diabetic rats compared to diabetic rats.
Conclusion: Caffeine and ALA have the potential to activate GPx-1 enzymes (in silico study). However, the use of a caffeine and ALA combination resulted in no significant difference in fasting blood glucose and oxidative stress conditions when compared to diabetic rats without additional induction (in vivo study).

Mitragyna speciosa as Lipolysis Stimulator

Posted on | by adminKR | Leave a Comment on Mitragyna speciosa as Lipolysis Stimulator

Backgrounds: Mitragynine is the most popular of the more than 50 alkaloids contained in M.Speciosa. In particular, the Mitragynine alkaloid has the potential to increase lipid (fats) metabolism through specific pathways such as adenylyl cyclase signaling via adrenergic receptors. In this case, Asp Amino acid and Ser are the types of residues that can activate adenylyl cyclase to initiate a series of activities in cells. Methods: This study used Mitragynine ligand and adrenergic receptors (α1b, α2a, α2b, α2c dan β1). The receptor candidates were tested using Autodock whose test results were presented in the form of tables and 3-dimensional images using the Biovia Discovery Studio. Results: Hydrogen bonds were formed between Mitragynine and the amino acids Asp and Ser at the β1-adrenergic receptor. The binding amino acids were found in Ser20 and Asp21 with energy bond of -5.26 kcal/mol and IC50: 111.35 ppm. Meanwhile, at the adrenergic receptor α2b there was only Asp residue that formed hydrogen bond with Mitragynine namely Asp218A. The energy bond formed between the two was -5.19 kcal/mol and IC50: 125.04 ppm. Conclusion: Mitragynine has the potential to stimulate lipolysis through the pathways of α2b and β1-adrenergic receptors.
