Abstract

Research on marine natural resources as an excipient material of pharmaceutical product is still rare. One of the marine products is the green algae, Cladophora sp. High cellulose content causes Cladophora sp. which can be used as an alternative material of microcrystalline cellulose (SM). There are two stages to produce SM, namely delignification and hydrolysis. Delignification is the process of removing the lignin of complex compounds. The delignification process is carried out chemically in alkaline situation using a NaOH solution which dissolves lignin, carbohydrates, organic acids, and resins so that cellulose is released from its bonds. This is important because the presence of lignin may inhibit acid penetration prior to hydrolysis. Therefore, the purpose of this study is to investigate the effect of delignification by using NaOH solution at various concentrations (2, 4, and 6%) to cellulose content and physical character of microcrystalline cellulose from Cladophora sp. (SMC). In the hydrolysis process, 5% HCl solution was used. SMCs of various concentrations of NaOH were observed and the cellulose levels included alpha, beta and gamma levels. While the physical character observation is done on Scanning Electron Microscopy (SEM) test. Based on the cellulose content, the higher the concentration of NaOH used, the higher the alpha cellulose will increase. The opposite result occurs on the measurement of beta and gamma cellulose. Based on SEM test, it appears that there is no effect of increasing NaOH concentration on physical character of SMC.

Abstract

The stability of pharmaceutical preparations is a very important criterion for a good production result where the stability of the drug can be influenced by external factors such as temperature. The sample used was a vitamin C solution with another name Acidum Ascorbicum (ascorbic acid) with a molecular formula of C6H8O6 and a molecular weight of 176.13 g / mol where the solution was tested for stability using the Iodometric titration method. Based on the calculation results, the vitamin C levels obtained in sample I (without heating) were 0.16644% w/v, in sample II (heating for 30 minutes) was 0.06376% w/v, in sample III (heating for 60 minutes) which is 0.15675% w/v, in sample IV (heating for 90 minutes) is 0.15288% w/v, and in sample V (heating for 120 minutes) is 0.16063% w/v. Thus, an increase in temperature can accelerate the occurrence of reactions that can disturb a substance's stability. Vitamin C The longer the heating time, the more vitamin C is oxidized, so that the remaining vitamin C levels will decrease due to the decomposition process.

Abstract

Pemanfaatan limbah hasil pertanian yang berupa jerami padi varietas IR64 di Bali belum optimal. Jerami padi yang merupakan suatu biomassa lignoselulosa dengan kandungan selulosa sekitar 40% dapat dikembangkan sebagai bahan baku pembuatan microcrystalline cellulose (MCC). Penelitian ini dilakukan untuk mengetahui kandungan alfa, beta dan gamma selulosa dari selulosa mikrokristal yang dihasilkan. Kandungan alfa selulosa merupakan komponen selulosa utama yang berpengaruh terhadap tingkat kemurnian dari suatu selulosa mikrokristal. Metode pembuatan selulosa mikrokristal dari jerami padi dilakukan dengan proses delignifikasi dengan NaOH 15% dan proses hidrolisis menggunakan variasi konsentrasi HCl yaitu 1,5N; 2N; 2,5N; 3N dan 3,5N. Hasil penelitian menunjukkan bahwa kadar alfa selulosa tertinggi yang diperoleh adalah 91,95%. Dari hasil penelitian ini, terlihat bahwa penggunaan NaOH dalam proses delignifikasi dan HCl 3,5N sebagai agen penghidrolisis pada jerami padi varietas IR64 mampu menghasilkan selulosa mikrokristal dengan kandungan alfa selulosa tertinggi.

Abstract

Introduction: Hypertension is one of the biggest health problems for Indonesian people. Celery leaves are a plant that can be used to treat hypertension. Research shows that the ethanol extract of celery leaves at a dose of 150 mg / day can reduce blood pressure. Antihypertensive drugs have low oral bioavailability due to first pass metabolism in the liver. The use of transdermal patches can improve patient comfort and may improve low oral bioavailability. One of the important components in the patch preparation is a polymer matrix consisting of hydrophilic (PVP K-30) and hydrophobic (EC N-20) polymers. Methods: this review article using literature review and evaluation results from research journals. Results: Optimization of the formula for transdermal patch preparations was carried out using three variations of the ratio of PVP K-30 and EC N-20 for the transdermal patch polymer matrix, namely 1: 2, 2: 3, and 1: 3. The best transdermal patch formula of celery leaf ethanol extract in terms of physical characteristics parameters and has the potential to provide optimal release of active ingredients to reduce blood pressure, namely the formula with a combination of polymer matrix PVP K-30 and EC N-20 2: 3. Conclusion: The writing of this review article is to obtain the best comparison of hydrophilic polymer (PVP K-30) and hydrophobic polymer (EC N-20) in celery leaf extract patch preparations (Apium graveolens) which have the potential to provide optimal release of active ingredients to lower blood pressure.

Abstract

Abstract Alpha-mangostin is a xanthonoid compound contained in mangosteen rind (Garcinia mangostana L.) and has an antibacterial effect against Staphylococcus aureus, the bacterium that causes acne. In this study, mangosteen rind extract is formulated in a gel dosage form. This study aimed to determine the optimum formula, the physical and chemical properties as well as the optimum formula release profile of the gel dosage form of mangosteen rind extract. The mangosteen rind extract gel formula consists of viscolam, propylene glycol, glycerin, microcare®, ethyl acetate extract of mangosteen rind, and distilled water. The formula was optimized by varying the concentrations of viscolam (2% and 5%), propylene glycol (5% and 20%) and glycerin (2% and 15%) using a factorial experimental design program called Design Expert 7.0.0. The 8 formulas were developed into gel dosage form and the physical and chemical properties were then evaluated. The evaluation tests include viscosity, dispersive power, and pH tests. The evaluation results were processed using the Design Expert 7.0.0 program to determine the optimum formula. The results of the analysis showed the optimum formula of gel dosage form of mangosteen rind extract with viscolam percentage of 4.97%, propylene glycol of 9.91%, glycerin of 12.23%, microcare® of 0.3%, TEA (q.s), ethyl acetate extract of mangosteen rind of 1%, and distilled water of 45%. The evaluation results of the physical and chemical properties of the gel optimum formula revealed the viscosity of 2,345 cps, dispersive power of 6.59 cm, and pH of 6.74. Alpha-mangostin release test on the optimum formula revealed a flux value of 41.327 ?g/cm2/t1/2. From these results, it is concluded that the optimum formula has met the physical and chemical characteristics of a good gel.

Abstract

Familial hypercholesterolemia is a genetic disorder caused by mutations in the low-density lipoprotein receptor gene (LDLR) and the current treatment still focuses on symptom management. The aim of this study was to develop a lipid nanoparticle (LNP)-based delivery system for the CRISPR/Cas9 component in correcting LDLR gene mutations. LNPs were prepared using an ultrasonic-solvent emulsification technique by varying the surfactant: oil ratio (SOR), homogenization speed and time, and sonication time. Next, the LNP surface was modified by adding DSPE-PEG2000-NH2 and polyethyleneimine. The next stage is to design the single guide RNA (sgRNA) and Donor DNA wildtype (Donor DNA wt). This genetic material was complexed with LNP and then transfected into Hepa1-6 LDLR mt cells, an in vitro representation of cells suffering from familial hypercholesterolemia. This optimization process produced LNPs with a particle size of 118.6±0.8 nm and a polydispersity index of 0.34±0.03. The LNP surface modification resulted in a zeta potential of +7.5 mV. A transmission electron microscope (TEM) analysis howed spherical morphology with size distribution following a regular pattern. LNP cell viability tests showed good biocompatibility at concentrations <15 mM with a half-maximal inhibitory concentration (IC50) value of 27.7 mM. The dominant cellular uptake mechanism of LNP was through the clathrin-mediated endocytosis (CME) pathway. The Hepa1-6 LDLR mt cell model was successfully produced with the transfecting agent Lipofectamine 3000 by homology-directed repair (HDR) mechanism. The LNP-genetic material complex with a ratio of sgRNA:Cas9:Donor DNA wt (1:1:0.04) showed an increase in LDLR gene expression of 3.3±0.2 times and LDLR protein levels reached 12.95±0.25 ng/mL on day 4 after transfection. The results of this study indicate that the developed LNP-based delivery system has the potential for gene therapy applications in familial hypercholesterolemia.
