Abstract

Aedes aegypti is the vector that carries Dengue Hemorrhagic Fever (DHF). Various strategies have been implemented to control the spread of the Aedes aegypti, one of which is using temephos larvicide. The use of temephos causes Aedes aegypti resistance and environmental pollution. Therefore, it is necessary to develop a bio-larvicide using ceremai leaf (Phyllanthus acidus) and zodia leaf (Evodia suaveolens). This study aimed to determine the toxicity of ceremai leaf and zodia leaf extracts on the mortality of Aedes aegypti larvae. This type of research is a pure experiment using a Completely Randomized Design. The research sample was third instar Aedes aegypti larvae. There were 7 groups consisting of 1 negative control (aquadest and tween20), 1 positive control (temephos 0.008%) and 5 treatment groups (ceremai leaf extract and zodia leaf extract). Larval mortality data were observed after 24 hours of exposure. The results of the Kruskal Wallis test showed that there was a difference in mortality between groups with a value of p : 0.020 (p < 0.05). Zodia leaf extract at 0.2% has the highest toxicity to the mortality of Aedes aegypti larvae. The probit test results of zodia leaf extract showed LC50 and LC90 values of 0.075% and 0.121% within 24 hours of exposure. Zodia leaf ethanol extract has effectiveness as larvicide of Aedes aegypti.

Abstract

Cytochrome P450 monooxygenase (CYP71AV1) is a crucial enzyme in the artemisinin biosynthesis pathway. This enzyme oxidized Amorpha 4,11 diene to produce artemisinic acid. This study aimed to in silico design high-level expression of CYP71AV1 in the E.coli system. In silico techniques are highly suitable for designing protein recombinant production before entering the laboratory. The amino acid sequence of CYP71AV1 was back-translated to the DNA sequence and adapt to E.coli codon usage by using Gene Designer. The DNA sequence of optimized CYP71AV1 was analyzed using Rare Codon Analysis to assess the expression efficiency in E.coli. The protein solubility prediction was determined using the SoDoPe tool. The optimized CYP71AV1 was determined to have a CAI 0.81, a GC content of 53.08 %, CFD with low frequency, and no negative cis or repeat elements. The result of the probability of solubility of CYP71AV1 was 0.6207 when expressed in E.coli. The MBP fusion partner can be used to increase the solubility of CYP71AV1. The in silico results showed the possibility of high-level protein expression of optimized CYP71AV1 in the E.coli system.

Abstract

HAMIN® is a self-emulsifying base composed of a mixture of hydrogenated palm kernel oil and hydrogenated palm kernel stearin. This formulation not only enhances the aesthetic quality of products but also simplifies the manufacturing process, as it eliminates the need for additional emulsifying agents to form a stable cream. Due to these properties, HAMIN® is considered highly suitable for the development of both pharmaceutical and cosmetic formulations. Despite its potential applications, no prior research has investigated the optimal ratio of HAMIN® palm fat base to distilled water distilled waterrequired to achieve desirable physical characteristics and drug release properties in cream formulations. Therefore, this study aims to determine the optimum composition of HAMIN® palm fat base and distilled water for the formulation of diphenhydramine hydrochloride cream. The optimization process was conducted using the simplex lattice design (SLD) method, a statistical approach commonly employed to evaluate and optimize multicomponent formulations. The experimental results demonstrated that increasing the concentration of HAMIN® palm fat base had a dominant effect on enhancing the pH, viscosity, adhesion, and stability of the cream. Conversely, a higher concentration of distilled water significantly improved spreadability, extrudability, and drug release flux. These findings indicate that the selection of base composition plays a crucial role in determining the overall performance of the cream formulation. The optimal formulation, as determined through SLD analysis, consisted of 41.667% HAMIN® palm fat base and 48.333% distilled water, achieving a desirability index of 0.649. This composition represents the most balanced formulation in terms of physical stability and drug release, making it a promising candidate for further pharmaceutical and cosmetic applications.

Abstract

Eksplorasi agen kemopreventif kanker masih terus dikembangkan, terutama yang berasal dari bahan alam. Hal ini didasari oleh keinginan untuk menekan angka kematian akibat kanker dan mengurangi efek samping yang ditimbulkan oleh terapi kanker yang saat ini digunakan. Penelitian ini ditujukan untuk mengetahui aktivitas sitotoksik daun beluntas (Pluchea indica Less.) terhadap sel kanker leher rahim yang merupakan kanker ginekologi peringkat pertama yang menyerang wanita. Aktivitas sitotoksik dilakukan terhadap ekstrak n-heksana, diklorometana, dan metanol daun beluntas terhadap sel HeLa dengan metode perhitungan langsung menggunakan bantuan perwarna trypan blue. Nilai IC50 dari ketiga ekstrak daun beluntas berturut turut adalah 18,06 μg/ml, 74,56 μg/ml, dan 31,21 μg/ml. Ketiganya memberikan perbedaan yang signifikan. Ketiga ekstrak yang diuji memiliki aktivitas sitotoksik dan dapat dikembangkan sebagai kandidat agen kemopreventif kanker. Namun masih perlu diteliti lebih lanjut bagaimana mekanisme aksi yang menjadi perantara aktivitas sitotoksik tersebut.

Abstract

The iler plant (Coleus atropurpureus) can be used as an efficacious medicinal plant. The chemical contents of the iler plant include essential oils, alkaloid, polyphenols, tannins and flavonoids. This content can be used as an antibacterial. This study aims to determine the antibacterial activity of iler leaves (Coleus atropurpureus) against bacterial folliculitis (Staphylococcusaureus). The NADES combination used is choline chloride:sorbitol with a ratio of 1:1, 2:1, and 3:1. The extraction method uses the UAE method and the antibacterial activity test uses the well diffusion method. The positive control used was Ciprofloxacin. The diameter of the inhibition zone for S. aureus bacteria is in a ratio of 1:1 (4,53 mm), 2:1 (6,29 mm), and 3:1 (8,12). The results of the phytochemical screening test obtained showed that the NADES extract of Iler leaves was positive for containing alkaloids, flavonoids, polyphenols and tannins.

Abstract

Diclofenac sodium, a widely used NSAID, has limited skin permeability, which reduces its topical efficacy; therefore, a gel-cream formulation combining the rapid absorption of gels with the emollient properties of creams is proposed to enhance drug penetration and patient comfort. To further improve delivery, HAMIN™, a novel natural palm oil–based base with excellent biocompatibility and lipid-enhancing properties, will be combined with HPMC K100M. This thickener stabilises viscosity and prolongs skin contact time, supporting better absorption. This study aimed to develop and optimise a topical gel cream for diclofenac sodium using HAMIN™ and HPMC K100M to achieve ideal physical properties and improved skin penetration. The formulation was statistically optimised using a Simplex Lattice Design (SLD), with HAMIN™ (X₁) and HPMC K100M (X₂) as independent variables, and pH (Y₁), spreadability (Y₂), viscosity (Y₃), extrudability (Y₄), release flux (Y₅), and permeation flux (Y₆) as dependent responses. Optimisation with Design Expert version 13 yielded the ideal composition of 16.84% HAMIN™ and 1.16% HPMC K100M, resulting in predicted values of pH 5.07, spreadability 7 cm, viscosity 4502.25 mPas, extrudability 78.98 N/s, release flux 70.61 µg/cm²√min, and permeation flux 0.4868 µg/cm²/min, with a desirability score of 0.829. Despite a slightly lower release flux, the optimised HAMIN™ and HPMC K100M-based gel cream demonstrated superior skin permeation compared to a commercial emulgel for up to 300 minutes. The incorporation of HAMIN™, a natural palm oil base, offers a novel and effective strategy to enhance the topical delivery of diclofenac sodium via a statistically optimised gel cream formulation.
