Abstract

Aim To compare the dissolution profi les of various enteric-coated low-dose acetylsalicylic acid (ASA) tablets marketed in Indonesia.Methods The dissolution study was carried out according to US Pharmacocopoeiae (USP) /European Pharmacopoeiae, method A, using USP apparatus 1 (basket) 100 rpm, with 2 media: 0.1 N HCl, 120 minutes for acid stage, and phosphate buffer pH 6.8, 90 minutes for buffer stage. The sampling points were 120 minutes for the acid stage, and every 10 minutes until 90 minutes for the buffer stage. The acetylsalicylic acid was assayed using spectrophotometry at 280 nm for the acid stage, and at 265 nm for the buffer stage. The free salicylic acid was determined only at the end of the buffer stage with HPLC method. There were 6 test products (Cardio Aspirin® 100 mg, Aptor® 100 mg, Ascardia® 80 mg, Thrombo Aspilet® 80 mg, Astika® 100 mg and Farmasal® 100 mg), 3 batches for each product, and 6 units for each batch.Results The amount of ASA released from each ASA product tested at the end of acid stage (120 minutes) ranged from 1.79% for Cardio Aspirin® to 6.92% for Thrombo Aspilet®, all conformed to the compendial requirement for enteric-coated product (< 10%). The amount of salicylic acid observed at the end of the dissolution test ranged from 3.47% for Cardio Aspirin® to 10.90% for Astika® and 11.90 % for Thrombo Aspilet®. Thrombo Aspilet® showed sustained-release properties, causing high variability in ASA release, such that one of the 3 batches tested did not fulfill the compendial requirement of more than 75% (the release was only 55.11%). High variability in ASA release between batches was also found with Farmasal® at 10, 20, and 30 minutes in buffer medium. The lowest effective dose of ASA as an antiplatelet drug for longterm use is 75 mg of plain ASA, and this is equivalent to 100 mg of enteric-coated ASA.Conclusions All of the low-dose ASA preparations marketed in Indonesia are enteric-coated products, while Thrombo Aspilet® is not only an enteric-coated but also a sustained-release product. Cardio Aspirin®, followed by Aptor®, has the right dose for low-dose enteric-coated preparation (100 mg), produces consistent ASA release between batches,and the most stable towards deacetylation (antiplatelet inactivation).

Abstract

Ketoprofen  is  one  of  non  steroidal  anti  inflammatory  drugs  (NSAID)  used for  rheumatoid  arthritis.  However,  unpleasant  taste of  ketoprofen  leads  to difficulty  in  the  formulation,  in  particular  for  oral  route.  Therefore,  in  present study, a technique to mask the unacceptable taste of ketoprofen was developed. Then,  a  fast  disintegrating  tablet  on  this  inclusion  complex  was  established  for rapid  release  and  faster  analgesic  effect  of  ketoprofen.  Taste  masking  was prepared  by  complex  inclusion  with  β-cyclodextrin.  The  ratio  of  ketoprofen  and β-cyclodextrin  was  varied.  The  fast  disintegrating  tablet  was  formulated  with direct compression using various ratios of mannitoland lactose as tablet diluent, the main factor influencing the successful of fast disintegrating tablet. Evaluation of  final  product  was  performed  according  to  compendial  standard  and  specific requirements  for  fast  disintegrating  tablet.  The  best  ratio  from  ketoprofen  and β-cyclodextrin  was  2:3  with  concentration  of  ketoprofen  in  inclusion  complex was  40.32%.  The  tablet  met  standard  requirement  was resulted  with  the composition  of  ketoprofen-cyclodextrin  equivalent  to  50  mg  of  pure  ketoprofen and mannitol and lactose (ratio 1:1) as tablet diluent. Fast disintegrating tablet of  modified  ketoprofen  in  inclusion  complex  was  fulfilled  standard  specification for ketoprofen tablet with better acceptance.Key words:ketoprofen, inclusion complex, fast disintegratingtablet, beta cyclodextrin.

Abstract

Poly (D,L-lactide acid) has been used as scaffold and controlled release device for protein such as growth factor in tissue engineering. In this study, PDLLA microparticles were made and papain was used as model protein. Protein was encapsulated in microparticles using water-oil-water (W1/O/W2) and solid-oil-water (S/O/W) emulsification-solvent evaporation. Types of encapsulation methods and ratios of papain-PEG 20000 were observed in this study to provide the highest encapsulation efficiency. The entrapment efficiency made by W1/O/W2 method was 6,38%±0,025,  whilst S/O/W using ratios of papain-PEG 20000 1:1 ; 1:4 ; and 1:5 were 6,24%±0,91 ; 30,15%±1,66 and 60,67%±4,93, respectively. To conclude, S/O/W is the best method to encapsulate protein with highest entrapment efficiency.

Abstract

Recombinant human Granulocyte Colony Stimulating Factor (G-CSF) has been produced in a soluble form in Escherichia coli BL21 (DE3) as a fusion protein. The open reading frame of G-CSF was synthetically constructed in previous work and was codon optimized for best expression in E. coli. In this research, the gene was fused to thioredoxin (Trx) at the N-terminal in pET32 vector. The purpose of this research was to optimize the overproduction and purification processes to obtain high yield recombinant protein in soluble form, and to characterize the Trx-G-CSF fusion protein. Overproduction was performed using IPTG induction method for 3 and 6 hours. The protein was purified by Ni-NTA affinity chromatography and separated using gradient concentration of imidazole. The purified protein was then characterized by SDS-PAGE and Western Blot analysis. Further, enterokinase was used to separate G-CSF from the fusion protein. The purified form of G-CSF was subsequently characterized using Western Blot and mass spectrometry using MALDI-TOF. The results showed that the fusion protein was successfully produced in soluble part as much as 48.25% were obtained after 3 hours of induction. The yield of  fusion protein was 67.37%  from total protein (229.65  mg protein/L culture). The Western Blot analysis showed the G-CSF band at around 18.6 kDa. Mass spectrometry with MALDI-TOF/ TOF revealed that 25.86% of amino acid residue was recognized as part of human G-CSF sequence.

Abstract

   The main requirement of transfection agent has to condense DNA in nanoparticle size, protect the DNA from nucleases and other degrading enzymes during its transport in cell cytoplasm and nucleus and should not toxic to target cells. In this research, lipopeptide composed of palmitoyl (C-16) and short peptide sequence have been designed fully synthesized and tested to DNA condensation capability and toxicity. The DNA condensation study was performed using EtBr exclusion assay and cytotoxicity determination was carried out by colorimetric MTT assay. It was revealed that lipopeptide-based transfection agent of Pal-CKKHH and Pal-CKKHH-YGRKKRRQRRR-PKKKRKV condensed DNA molecules efficiently. The lipopeptide was less toxic compared to Lipofectamine and Poly-L-Lysine, that shown by 90% of CHO-K1 cells remained viable when they were treated with 4.36 µM Pal-CKKHHYGRKKRRQRRR-PKKKRKV. Meanwhile, there were only ~75% and 80% of CHO-K1 viable cells when it was treated with PLL and Lipofectamine®2000, respectively. Moreover, cell viability of HepG2 was ~ 75% after treated with 2.18 µM of Pal-CKKHH-YGRKKRRQRRR-PKKKRKV and decreased to ~65% when the lipopeptide concentration increased to 8.72 M. In summary, the synthesized lipopeptide condenses DNA molecules efficiently, less toxic than Lipofectamine®2000 and PLL and has possibility to be explored as a non-viral gene delivery vehicle.

Abstract

Silimarin merupakan senyawa flavonolignan yang berasal dari tumbuhan Silybum marianum (Asteraceae). Silimarin memiliki efek farmakologi sebagai antikanker dan hepatoprotektor, tetapi senyawa ini memiliki kelarutan yang rendah dalam air. Tujuan penelitian ini adalah mengembangkan formulasi silimarin dalam sistem pembawa nano dengan teknik desolvasi. Pembawa yang digunakan adalah serum albumin (bovine serum albumin/BSA). Kombinasi silimarin dalam BSA diharapkan dapat meningkatkan efikasi silimarin sebagai anti kanker karena permeabilitas BSA yang lebih baik pada sel kanker. Evaluasi standar terhadap nanopartikel silimarin-BSA meliputi ukuran dan distribusi ukuran partikel, zeta potensial, morfologi nanopartikel, kristalinitas, sifat termal, spektroskopi inframerah, efisiensi penjeratan serta profil pelepasan silimarin dari BSA nanopartikel pada 2 media   berbeda (HCl 0,1 N & PBS pH 7,4). Nanopartikel BSA- silimarin memiliki ukuran partikel 174,23 ± 13,94 nm; distribusi ukuran partikel 0,185 ±0,052; efisiensi penjeratan 90,54 ± 0,098 %; loading capacity 30,18 ± 0,036 % dan zeta potensial -1,62 mV. Hasil analisis menggunakan DSC (differential scanning calorimetry), XRD (X-ray diffraction) dan spektroskopi inframerah menunjukan bahwa nanopartikel silimarin berhasil terenkapsulasi di dalam nanopartikel BSA, dan BSA-silimarin memiliki bentuk amorf. Setelah 1 jam uji pelepasan, terdapat sebanyak 21,89% silimarin terlepas dalam HCl 0,1 N dan 54,84% silimarin terlepas dalam PBS pH 7,4 sehingga dapat disimpulkan bahwa silimarin-BSA memiliki kelarutan yang baik dalam air. Oleh karena itu,  perlu  dilakukan  pengujian  lebih  lanjut  untuk  mengkaji  akt ivitas  serta  perilaku silimarin-BSA in vivo untuk mengkonfirmasi data in vitro.

Abstract

Digital marketing adalah salah satu cara pemasaran yang saat ini sedang diminati oleh para pelaku usaha, melalui digital marketing ini pelaku usaha bisa memasarkan produk hasil buatannya. Pelaku UMKM di Desa Muntung memproduksi snack atau makanan yang berbahan baku dari tepung terigu. Produk kembang jambu ini merupakan salah satu produk unggulan dan diminati oleh warga masyarakat di sekutar Desa Muntung. Pemasaran kembang jambu masih menggunakan pemasaran manual, seperti dititipkan di warung-warung terdekat, atau bahkan para pembeli datang langsung ke lokasi produksi kembang jambu tersebut. Hal inilah yang menjadikan Kelompok KKN Unnes yang berjumlah 13 orang untuk membantu para pelaku UMKM dalam teknik pemasarannya. Ada 2 UMKM yang sudah berjalan lancar di Desa Muntung ini, namun masih disayangkan jika teknik pemasaran dan pengemasan masih tradisional. teknik pemasaran melalui digital marketing adalah salah satu upaya untuk meningkatkan produksi karena melalui digital marketing khalayak umum akan lebih tau produk-produk yang dijual terlebih jika memang produknya merupakan produk yang berkualitas. Sementara itu, dari hasil wawancara awal dengan pelaku usaha mikro produk makanan, baik produsen maupun retailer mengakui bahwa kemasan produk mempengaruhi citra produk. Namun pemahaman mereka tentang kemasan produk masih sangat minim. Menurut mereka kemasan hanya sekedar wadah dan pembungkus makanan agar tidak rusak. Permasalahan lain yaitu mereka tidak mempunyai kemampuan dana untuk mengemas produknya dengan baik. Dengan situasi persaingan semakin tajam, desain sebuah kemasan merupakan suatu nilai tambah, dapat berfungsi sebagai media promosi dan untuk menjaring konsumen.
