Abstract

The aims of the study was to determine antihyperuricemic activity of ethyl acetate and ethanol extractsof snake fruit (Salacca edulis Reinw.) var. Bongkok on Wistar male rats. Wistar male rats administered with 100 and 200 mg/kg b.w ethyl acetat extract and 200 mg/kg b.w ethanol extract and simulationsly induced with potassium oxonate peritoneally and uric acid orally showed descreased uric acid serum level significantly as compared to control group at 6th and 7thhour (p < 0.05). Meanwhile ethanol extract at 100 mg/kg bw did not affect uric acid serum level significantly. Determination of uric acid level in urine of the rats, indicated that administration ofethanol extract at 200 mg/kg bw, orprobenecid as a standard at 45 mg/kg bw, increased excretion of urine uric acid level significantly as compared to control group at 7thhour (p < 0.05). Additionally, administration of ethyl acetate extract at 100 and 200 mg/kg bw did not show an increase of uric acid excretion in urine. Mechanism of action of the ethyl acetate extract and ethanol extract as an antihyperuricemic agent has been proposed by inhibition of xanthine oxidase activity wich decrease the synthesis of uric acid. Hence, the mechanism of action of antihyperuricemia of the ethanol extract was suggested to be an uricosuric i.e. increases the excretion of urine uric acid and xanthine oxidase inhibitory.

Abstract

Andrographolide,  a  bioactive  component  of  Andrographis  paniculata (Burm.F)  Nees,  is  the  major  lactone  diterpenoidal  bicyclic  constituent  in  this plant  which  has  proven  to  exert  anti-inflammatory  activity  in  vitro  which  was occurred via  several mechanism, e.g inhibition of inducible nitric oxide synthase (iNOS),  inhibition  of  radical  oxygen  species,  and  inhibition  of  NF-kappaB activation. The labeling with radionuclide is often used for therapy, detection and quantification of metabolites in the body. Even though the metabolites are very low  in  concentration  they  can  be  detected  by  the  energy  they  emitted. Radionuclide  can  be  used as  radiotracer  to  detect  whether  drug  really interacts with  its  target.  The  objective  of  this  research  is  to  synthesize 131I-labelled andrographolide  and  to  study  its  biodistribution  in  mice  to  understand  the location  of  its  organ  target.  Indirect  radioiodination  of  andrographolide  wascarried  out  by  using  bromine  as  the  leaving  group  and  followed  by  fast iodination  at  40oC,  yielded  72.6  %  purity  of  the  labeled  compound.  Iodination was occurred through proton substitution at C-12. Then the andrographolide-131I was  injected  into  lateral  vein  of  mice’s  tail  to  study  its  biodistribution.  The compound  was  distributed  in  all organs  with the  highest  accumulation  occurred in  the  stomach  (16.87  %/gram  organ).  The  result  showed  that  inducing  the animals  with  LPS  caused  inflammation  in  the  stomach  and  increased  the production  of  prostaglandin  as  proven  by  the  distribution  of  the  radioligand  in that organ.Key words: andrographolide, radioiodination, anti-inflammatory, biodistribution

Abstract

Quantitative analysis of bioactive peptide mostly conducted by measuring the activity. While the determination of peptide content in natural sources has been conducted using various instruments, vibrational spectroscopy remains underutilized. Here, we attempted new developed method in peptide quantification and degradation kinetic analysis using Fourier-Transform Infrared Spectroscopy. Bovine Serum Albumin was used as standard protein in method development and validation. Peptide content was estimated by converting peak area to concentration. The method was used to estimate peptide content in Canarium nut protein and its hydrolysates, which potentially hold biological activity. Kinetic study was conducted with microwave as an accelerator for hydrolysis, an apparatus rarely used in peptide study. Amide I band on wavenumber range of 1724.05-1619.91 cm-1 was selected for analysis, considering its selectivity and linearity. The method also met other validation requirement, including accuracy and precision. When applied in quantitative analysis, the method was able to calculate peptide content decrease in Canarium nut protein after hydrolysis using papain (38.24%), pepsin (33.67%) and alkaline reagent (28.53%). In kinetic study, microwave-assisted peptide degradation exhibited logarithmic profile with the equation of y=-0.148ln(x)+0.9591 and R² value of 0.963. Based on these results, FTIR is useful in estimating peptide content and in analyzing degradation kinetic profile.
