Abstract

Neem plant is rich in bioactive constituents, which make it massively discussed the treatment of various diseases. A study on the immunomodulatory activities of neem is given here. This current work aimed to investigate the effects of neem leaf extract on immunocompetent cells. In vivo experiment was carried out using mice (Mus musculus)  induced with DMBA, comprising positive control, negative control, and treatments of neem leaf extracts (250, 500, and 1000 ppm). Data obtained from flow cytometric analysis were evaluated using BD Cellquest ProTM software, then statistically analyzed in SPSS version 21. Parametric analysis in one-way ANOVA was performed at a significance level of 5%. The significant difference was compared in the Duncan test. The results showed that administration of neem leaf extracts significantly affected the expression of CD4+, CD8+, CD25+, CD62L, IL-10, and IL-17 cells .Neem leaf extract has immunomodulatory activities by increasing pressure molecules and decreasing pro-inflammatory molecules

Abstract

Akway (Drimys piperita Hook f.) was known as an endogenous plant of Indonesia. This plant was investigated as free radical scavenger based on paramagnetic properties. This study aimed to identify the bioactive compound and the role of Fe metals ions to enhance the free radical scavenger capacity as Low molecular weight antioxidant (LWMA) of akway. This study was designed by ultra-performance liquid chromatography (UPLC) coupled with ultra-high-resolution time of flight-mass spectrometry detector (TOF-MS), docking (Pyrex and Discovery Studio 2016 Client) and pharmacokinetic properties prediction (SwissADME). UPLC-TOF-MS analysis showed that herbal akway bark has five molecular formula (C4H3N10O21-, C14H19N4O91-, C4H7N6O51-, C15H28NO31+, and C23H32NO71+). The docking was illustrated the complex binding akway formula with Fe and its role as a metal donor and metal acceptor. It also confirmed on pharmacokinetics properties prediction which molecular compounds of akway have aqueous solubility. It meant the herbal akway bark complexed to Fe could be a low molecular weight antioxidant and it could be escalated free radical scavenger capacity.

Abstract

Bacterial infection and antibiotic resistance are popular issues nowadays. Several pre[1]vious reports performed antibacterial screening activities involving natural herbs and synthetic drugs. Alanine racemase and transglycosylase are essential proteins for peptidoglycan membrane synthesis in bacteria and an alternative target for antibacterial performance. This study identified six flavonoid compounds in Syzygium myrtifolium to perform the antibacterial activity. In silico study was conducted for modelling flavonoids – protein complexes. Five flavonoids from S. myrtifolium were taken out of he canonical smiles from the PubChem database and modelled three-dimensional structure using ChemDraw and molView. Targeted protein, alanine racemase and transglycosylase were downloaded from Protein Data Bank with ID 4WR3 and 1SLY. Ligands and proteins were interacted by Molegro virtual Docker 5.0 and visualized by Discovery studio version 21.1.1. Five flavonoids showed inhibition with alanine racemase and transglycosylase in the same active sites of control and sodium benzo[1]ate. According to the binding energy, calopiptin performed the lowest binding energy value in alanine racemase complexes, while 2-Propanone, 1,3-bis(5-nitro-2-furanyl) showed the lowest value of four other flavonoids at transglycosylase complexes. The type of interactions were electrostatic, hydrogen bonds, hydrophobic interactions and unfavorable ones. Low binding energy and varied interaction types indicated tight of ligand-protein interaction. In summary, five flavonoids inhibited alanine racemase and transglycosylase, and the peptidoglycane membrane synthesis in bacteria might be inferred.
