An overview of the role of Zingiber officinale as an antimicrobial resistance (AMR) solution and a source of antioxidants

2023-03-28T14:08:09+07:00

In this review, we describe the known mechanisms of antimicrobial resistance which was increasing in this era, due to the misuse of antimicrobial agents such as antibiotics, or genetic and phenotypic mechanisms. In this review, the concerns, especially addressed by designated researchers in their study and WHO in their observations and reports, regarding the types or strains of bacteria with antimicrobial resistances were described. In addition, the predicted mechanisms that promote the development and occurrence of antimicrobial resistances, such as bacterial biofilm formation, horizontal gene transfer, genetic mutations, free DNA which contains antimicrobial resistance genes, plasmids transfer through transformation or conjugation from bacterial cell to cell were well described. In addition, we also tried to describe the use of Z. officinale. The antimicrobial capabilities of this herbal plant are attributed to its capacity to create many secondary metabolites with rather complicated structures that have antibacterial and antioxidant characteristics. Z. officinale had been used for many kinds of diseases treatment traditionally. And along the way, the advance techniques of research in chemistry and biology fields had found out the composition and bioactive compound. In this review, the common online databases such as PubMed, Semantic Scholar, Crossref, Medline, Scopus, and Web of Science (WoS) were utilized to conduct literature searches. According to recent progress of antimicrobial cases observed, the efforts to strengthen the surveillance, general health systems, tightened the antimicrobial medicine distribution rules, and education for public are indeed needed.

Basil Extract (Ocimum basilicum L) Exhibits Antidiabetic and Hepatoprotective Effects via SIRT1 and Peroxisome Proliferator-Activated Receptors (PPARγ) on Gestational Diabetes Mellitus Rats Model

2023-03-27T09:43:12+07:00

Gestational Diabetes Mellitus (GDM) is a disorder of carbohydrate metabolism that causes hyperglycemia and insulin resistance during pregnancy. Sirtuin 1 (SIRT1) and Peroxisome Proliferator-Activated Receptorγ (PPARγ) are genes that play a role in glucose metabolism. Dysregulation of SIRT 1 and PPARγ is associated with the GDM. Hyperglycemia in GDM induces inflammation and oxidative stress in hepatocytes causing liver damage. Basil extract (Ocimum basilicum L) is one of indonesia medicinal plant has been used as traditional medicice in diabetic disorder. This study aims to investigate the hypoglycemic activity of basil extract by evaluating the expression of SIRT 1 and PPARγ in GDM rats and investigate the potential hepatoprotective effect of basil extract by analyzing the rat’s liver histology. Twenty-four of pregnant rats were divided into four groups; negative control, positive group induced by streptozotocin 40 mg/kg BW intraperitoneally, and two groups of GDM rats treated with 100 mg/kg BW and 200 mg/kg BW of basil extract for 14 days. Blood glucose levels were examined with a blood glucose meter. The expression of SIRT 1 and PPARγ was assessed by the RT-PCR. Histological analysis of the rat`s liver was conducted to determine the percentage of cell damage and tissue edem The data were statistically processed using SPSS. The extract of basil at a dose of 200 mg/kg BW showed an anti-diabetic effect which decreased the glucose level concentration by about two times compared to the untreated rat. It enhanced the expression of SIRT-significantly with a value of p= 0.035 (p <0.05). Basil extract-treated group showed a trend of increasing PPARγ expression, but not statistically significant. In addition, HE staining on the liver showed a tendency to improve in the group given basil extract. This Study concluded that basil extract could increase SIRT 1 and potential to be an anti-hyperglycemic therapy with a hepatoprotective effect.

Optimization of Polysorbate 80 and Sorbitan Monooleate 80 aas Emulsifiers in Foundation Makeup Containing Ethyl Cinnamate

2023-03-29T11:39:24+07:00

Cosmetic foundation is a type of decorative makeup and commonly include a sunscreen agent. Ethyl cinnamate is one of the potential organic essential oil sunscreens. Nevertheless, there is little study on ethyl cinnamate usage in cosmetics, particularly oil-in-water foundation cream. Using an emulsifier in oil-in-water foundation cream a higher concentration does not guarantee higher oil phase recovery. However, using two combinations of emulsifier such as polysorbate 80 and sorbitan monooleate 80 with the optimum combination can be the right solution. This study aims to optimize polysorbate 80 and sorbitan monooleate 80 in a cream foundation using ethyl cinnamate as an active ingredient designed to have an effective ability to protect facial skin from ultraviolet radiation and are safe to use. The optimization formulas design of the emulsifier combination in foundation cream was made using the Simplex Lattice Design method with help Design Expert version 10.0.1. Parameter optimization were the value of pH, viscosity, spreadability, adhesion, and Sun Protection Factor (SPF) value. The stability test and skin irritation test of optimum formula were also conducted. As a positive control, Revlon Colorstay Foundation as a brand cosmetic foundation was used (National Food and Drug Agency of Indonesia number : NA18140300519). The optimum ratio of polysorbate 80 and sorbitan monooleat 80 were 9.565 and 1.435 with the physical characteristics of pH 6.478+0.008; viscosity 5844.2+31.82 cPs; spreadability 6.16+0.11 cm; adhesion 3.346+0.14 seconds; SPF Value 22.385+0.48, and no irritation symptoms.

Network Pharmacological Analysis Identifies the Curcumin Analog CCA-1.1 Targeting Mitosis Regulatory Process in HER2-Positive Breast Cancer

2023-03-29T10:49:55+07:00

Recent studies present that the CCA-1.1 (a curcumin derivative) impedes the proliferation of breast cancer cells (luminal, HER2-overexpressed, and TNBC cells). Currently, we analyze the possible target of action of CCA-1.1, particularly in breast cancer cells with HER2 amplification using bioinformatics analysis. The differentially expressed genes (DEGs) of HER2-positive breast cancer were retrieved from TCGA-BRCA data (via UALCAN). We used three web-based tools (Swiss Target Prediction, BindingDB, and TargetNet) to predict the potential target of CCA-1.1 using the SMILE-similarity feature. The functional annotation and network enrichment were processed in WebGestalt. The alteration of selected genes was observed in CBioPortal. The protein-protein interaction (PPI) network was constructed in STRING, then ranked based on the degree score using Cytohubba feature in Cytoscape. The survival analysis from the hub-gene was collected in GEPIA2 with selection only for HER2-positive breast cancer cases. The correlation between the hub genes and tumor-infiltrating immune markers was determined using TIMER web tools. The pathway network analysis highlighted the cell cycle regulation in mitosis as affected signaling amid the putative CCA-1.1 targets. We denoted eight potential genes that could be responsible for inhibiting mitosis regulation upon CCA-1.1 treatment, including AURKA, AURKB, PLK1, TPX2, KIF11, MELK, CDK1, and CHEK1. Several of the potential markers (AURKB, AURKA, CDK1, and CHEK1) revealed to be correlated with the immune cells’ infiltration markers. CCA-1.1 might regulate mitosis to induce cell cycle arrest and lead to cell death. The predicted targets of CCA-1.11 gave insight into the potency of CCA-1.1 to be with immunotherapy. Further validation of the data presented in the study is essentially needed to develop CCA-1.1 for breast cancer.

Clindamycin peel-off mask film, an effective formulation for C. acnes treatment: characterization and microbiological activity

2023-03-28T14:15:17+07:00

Clindamycin is the antibiotic of choice for treating Cutibacterium acnes (C. acnes) which was presented in various dosage forms such as topical solution, gel, and foam. In this current study, clindamycin was formulated as the peel-off mask gel, intending to form film, providing the drug release profile in a sustained manner leading to better antimicrobial efficacy and enabling peel-off after use. The peel-off mask gel was designed into many formulations with varying concentrations of film-forming agents. The major film-forming agent was 10 %w/w PVA that was combined with the additional film-forming agents PVP-K30 or SA. Clindamycin 1 %w/w was loaded in the selected formulations F18 (10 %w/w PVA and 20 %w/w PVP-K30) and F21 (10 %w/w PVA and 1.5 %w/w SA). The physical property evaluation of the peel-off mask gel showed that the types and concentrations of film-forming agents influenced the viscosity, spreadability, and film-forming ability. The film’s tensile strength indicating the preference of use was also determined. There was no interaction between the ingredients in the formulation evaluated by FT-IR, XRD, and DSC. The F18 and F21 formulations showed a good to very good spreadability and film-forming ability, a suitable tensile strength with a drying time of approximately 8 min, and pH 4-5. Both formulations provided the highest antimicrobial susceptibility for C. acnes compared to the blank film and the clindamycin solution indicating the potential to be developed as the new market formulation for acne treatment.

Co-crystallization of sofosbuvir with sugars for enhanced dissolution rate

2023-03-28T14:22:55+07:00

Sofosbuvir is one of the direct acting antiviral agents which is approved in the treatment of chronic HCV in combination with other agents. The low aqueous solubility of sofosbuvir resulted in slow dissolution which is supposed to be responsible for its low and variable bioavailability after oral administration. Accordingly, the objective of this work was to investigate the effect of co-crystallization of sofosbuvir with hydrophilic sugars on its crystalline structure and dissolution rate. Mixtures of sofosbuvir with hydrophilic sugars at various molar ratios were prepared by ethanol assisted kneading followed by drying. The dry products were then characterized by attenuated total reflectance fourier transform infrared spectroscopy (ATR FTIR), differential scanning calorimetry (DSC), powder X-ray diffraction (XRD) and in vitro dissolution studies. Combined instrumental analysis reflected development of new crystalline species of co-crystal type. This was evidenced by the existence of hydrogen bonding as shown from FTIR spectra, change in the thermal behaviour and appearance of new diffraction peaks in the diffractograms recorded by XRD. The co-crystallization was associated by weakening of intermolecular bonds which resulted in significant increase in the dissolution rate of sofosbuvir. The study introduced hydrophilic sugars as co-crystal co-formers for enhanced dissolution of sofosbuvir.
