Abstract

Niosomes  are  vesicles  system  that  have  applications in  the  delivery  of lipophilic,hydrophilic  and  amphiphilic  drugs.  Ketoprofen,  is  very  insoluble  in water  and  cause  gastric  irritation  when  taken  orally.  It  is  very  important  to develop a transdermal delivery system for ketoprofen. This research was aimed to  design  niosomes  which  can  deliver  ketoprofen  via transdermal  route. Experiments  were  designed  to  incorporate  ketoprofen into  niosomes   with  lipid film  hydration  method.  Lipid  mixture  consist  of  cholesterol  and  sorbitan  ester (span  20,  60,  80).  Niosomes  which  can  deliver  ketoprofen  trough  the  skin barrier  determined  by  calculating  amount  of   ketoprofen  in  the  blood  of  rabbit. The  type  of  sorbitan  ester  was  chosen  based  on  the  highest  drugs  entrapment and  ketoprofen  as  drugs  model.  Preparation  of  niosomes  was  optimized  for  the highest  percent  drug  entrapment  by  increasing   molar  concentration  of  lipidmixture  with  the  stable  comparison  of  1:1.  This  research  result  are  niosomes with  lipid  mixture  span  60  and  cholesterol  have  the highest  drug  entrapment efficiency  of  niosomes  66.16%  with  range  size  1–6  µm.  Niosomes  can  deliver ketoprofen  to  the  systemic  circulation  via  transdermal  route  with  plasma  level concentration achieved in 1.5 hour.Key words: niosomes, ketoprofen, transdermal

Abstract

Glochidion philippicum has been suggested to exhibit considerable pharmacological potential, yet its chemical composition and bioactivity remain inadequately explored. The aim of this study was to investigate the chemical fingerprint and antioxidant properties of G. philippicum leaf extracts using Fourier-transform infrared spectroscopy (FTIR) with chemometric analyses, and in vitro and in vivo evaluations. Four extraction methods (maceration, reflux, ultrasound-assisted extraction (UAE), and microwave-assisted extraction (MAE)) were optimized with water, 70% ethanol, ethyl acetate, and n-hexane as solvents. FTIR profiles were analyzed with principal component analysis (PCA), hierarchical cluster analysis, and orthogonal partial least squares discriminant analysis. An in vitro study assessing the free radical scavenging capacity was conducted using the 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), 2,2-diphenyl-1-picrylhydrazyl (DPPH), and ferric-reducing antioxidant power (FRAP) methods, while in vivo evaluations were conducted using Drosophila melanogaster to measure antioxidant enzyme activity and expression of endogenous antioxidant-related genes. FTIR profiles identified functional groups contributing to antioxidant activity. In vitro assays using ABTS and FRAP methods revealed that extracts obtained with 70% ethanol and water exhibited the highest antioxidant activity, attributed to key functional groups such as C=C (aromatic), O−H (acidic), N=O (nitro), and C−O (ester). In vivo studies showed that ethanol-based MAE extracts (MAEEO) significantly improved the survival of autoinflammatory PGRP-LBΔ mutant larvae exposed to heat-killed Escherichia coli. Real-time quantitative PCR analysis indicated this effect was dependent on endogenous antioxidant gene activation. The study highlights that G. philippicum leaf extracts as a natural source of bioactive compounds with exogenous antioxidant properties, offering potential for therapeutic applications.

Abstract

This study aimed to compare the effects of simvastatin, rosuvastatin, and fenofibrate therapies on the body weight and lipid profiles of the female rats receiving a combination of oral contraceptives (COC) and a high-fat diet (HFD). Twenty female Wistar rats (130-200 g) were divided equally into four groups. The rats received a standard diet for seven days, and their baseline lipid profiles were analyzed. All rats also received COC containing 15.1 g/kg levonorgestrel/3.1 g/kg estradiol with HFD for 60 days. Starting on day 31, the rats were given the respected treatment. The control group received the vehicle, whereas the others were treated with either simvastatin (2.1 mg/kg), rosuvastatin (0.5 mg/kg), or fenofibrate (8.2 mg/kg). Blood samples were taken on days 30 and 60. The results showed that the administration of COC+HFD and vehicle for 30 days increased the rats body weight and dyslipidemia, characterized by a significant decrease in Low-Density Lipoprotein (HDL) and an increase in total cholesterol (TC) and triglycerides (TG) levels (P0.05). Among the treatments, only fenofibrate was found to be able to prevent a significant weight gain in rats. Both fenofibrate and rosuvastatin inhibited a significant rise in TG and TC levels. Meanwhile, the simvastatin administration failed to do the same. Although statistically insignificant, all treatments increased rats HDL levels. Thus, it can be concluded fenofibrate was the most effective treatment among all in reducing weight gain and improving the lipid profile of dyslipidemic rats induced by oral contraceptives and a high-fat diet.
