One of the world's silent killer diseases is hypertension. Hypertension occurs when angiotensin I is converted to angiotensin II, causing vasoconstriction and decreasing sodium and water excretion. The mechanism of angiotensin I conversion to angiotensin II appears in the presence of the Angiotensin-Converting Enzyme (ACE). Dayak onion is widely used as an antihypertensive in traditional medicine. This study aims to identify secondary metabolites, determine total flavonoid content, determine extract quality parameters, and ACE inhibitory activity of the Dayak onion herb. Dayak onion herb was extracted with 70% ethanol by kinetic maceration, followed by phytochemical screening, extract quality assessment, and ACE inhibitory test. The results show that the Dayak onion extract has a good properties with total ash content of 4.49%, water-soluble ash content of 4.00%, acid-insoluble ash content of 0.41%, drying shrinkage of 9.70%, water content of 5.72%, solvent residue of 0.67%, Pb heavy metal content of 0.2908 mg/kg, Cd heavy metal content of 0.0880 mg/kg, total plate number ≤103 colonies/g, and yeast mold numbers ≤103 colonies/g. Dayak onions herbs extract contains flavonoid, alkaloid, saponin, tannin, triterpenoid, quinone, steroid and essential oil compounds. The total flavonoid content was 2.24% and the IC50 in ACE inhibitory test was 98.5 ± 0.77 ppm, making it two times more potent than Veronica biloba and Schoenoplectus triqueter. The result of this study indicates that the Dayak onion herb can be used as an alternative for antihypertensive treatment.

Antibiotic resistance is a critical issue that threatens global health. Streptococcus pneumoniae, a common respiratory pathogen, has developed resistance to β-lactam antibiotics, which is of great concern. The primary mechanism of β-lactam resistance in S. pneumoniae is the acquisition of PBP genes from related species through recombination, resulting in changes in penicillin-binding proteins that affect cell wall synthesis. This mini-review summarized the understanding of β-lactam resistance in S. pneumoniae, focusing on the mechanisms and factors influencing resistance development. We conducted a comprehensive literature search using PubMed and Google Scholar, with the keywords ‘Resistant Streptococcus pneumonia’, ‘Mechanism of Streptococcus pneumoniae resistant’, and ‘Penicillin Resistant on Binding Protein of Streptococcus pneumonia’. Our literature review revealed that the prevalence of β-lactam resistance in S. pneumoniae has increased, leading to treatment failures and mortality rates. In addition to acquiring PBP genes, mutations in other PBP and non-PBP genes can contribute to resistance. Furthermore, S. pneumoniae has intrinsic resistance to various antibiotics, including first-generation polypeptides, aminoglycosides, and quinolones. Our review highlights the importance of understanding the complex mechanisms of β-lactam resistance and the need for continued efforts to monitor and control antibiotic resistance in S. pneumoniae. Further research is needed to explore novel strategies for combating antibiotic resistance in this pathogen.

Compatibility is one of the quality characteristics of intravenous (IV) preparations that influences the effectiveness of patient therapy in the intensive care Unit (ICU). This study aimed to determine the compatibility profile of IV medication formulations given to ICU patients. This prospective observational research was undertaken on patients in the ICU of a private hospital in Samarinda. The data on the intravenous combination of drugs were compared in this study utilizing the ASHP Injectable Drug Information literature 21st edition, Injectable drug guide, and Manual Book. Injectable Drug Mixing was published in 2009 as a resource for determining the compatibility of intravenous formulations. Using certain criteria, combinations of intravenous medicines and their solvents are classed as compatible (C), incompatible (I), and unknown (U). The ICU had 25 patients, 15 of whom were male, and 10 of them were female. There is no mixing of drug compounds containing incompatible solvents. All drugs were carried out with 100% compatible solvents. The limited information related to the compatibility and stability of these intravenous preparations encourages continuous monitoring of the patient's condition and drug levels.

Tamoxifen is the most commonly used anti-estrogen adjuvant therapy for estrogen receptor-positive breast cancer. However, it is associated with an increased risk of some serious side effects, such as uterine cancer, stroke, and pulmonary embolism. The flavonoid compounds in the leaves of A. manihot inhibited the growth of 4T1 breast cancer cells at a CTC50 concentration of 185.06 μg/ml. Therefore, this study aims to examine the molecular interactions and pharmacophore modeling based on the interaction of 4-OHT with human ER, followed by the molecular docking of the flavonoid derivatives with human ERα. The molecular docking simulations and 3D structure-based pharmacophore models were used to identify the molecular interactions of flavonoid derivatives in A. manihot on estrogen receptors (ERα) (PDB ID: 3ERT). The results showed that the binding energies of the flavonoid derivatives in isorhamnetin and isoquercitrin were -8.68 kcal/mol and -8.75 kcal/mol, respectively. This compound also interacted with Arg394 and Glu353 important amino acid residues in the ERα-binding pocket. Meanwhile, the pharmacophore fit scores of isorhamnetin and isoquercitrin were 82.36% and 84.91%, respectively. The flavonoid derivatives in A. manihot had pharmacophore fit resulting from the 4-OHT complex with ER, and therefore they had potential as ERα antagonists. Out of the 10 flavonoid derivatives, isorhamnetin and isoquercitrin showed the best docking scores and could be used as candidates for new anti-breast cancer drugs with antagonistic activity against ERα.

The co-amorphous solid dispersion system is one of the methods to improve the physicochemical characteristics and stability of a drug. With the appropriate material ratio and preparation method, a co-amorphous solid dispersion system can increase the bioavailability of the drug due to an increase in solubility. In addition, the co-amorphous system will maintain its amorphous shape longer than a single compound. However, using unsuitable materials and methods for co-amorphous fabrication will precipitate them and diminish their bioavailability. As a result, exploring the fundamentals of co-amorphous manufacturing methods is essential. This article discusses the physicochemical properties and solubility of co-amorphous mixtures prepared by solvent evaporation, milling, and quenching methods. Scopus, PubMed, and Google Scholar literature were obtained using the keywords 'co-amorphous preparation', 'co-amorphous method', 'solvent evaporation for co-amorphous preparation', 'milling methods for co-amorphous preparation', and 'quenching method for co-amorphous preparation'. We excluded literature whose application was not in the medical field. Based on the findings, the co-amorphous preparation methods have their respective advantages and disadvantages. Solvent evaporation can only be used on a small scale. Milling techniques are laborious and time-consuming but have a large yield and less chemical destruction, while the quenching method is only intended for thermostable compounds.

A pharmaceutical industry is highly regulated by a quality policy in its management. The principles of Quality by Design (QbD) must be applied to ensure the development of pragmatic and systematic methods while managing the risks associated with analytical methods. Quality by Design (QbD) is a scientific way to develop easy and robust analytical techniques for critical analysis. Quality by Design (QbD) is a systematic approach to product or method development that starts with predetermined goals and uses a science and risk management approach to achieve product and method understanding. The concept of risk management is deeply integrated into the quality assurance system to ensure pharmaceutical quality and patient safety. In the context of quality control, detecting impurities in raw materials and finished products is a major concern. Analytical Quality by Design (AQbD) aims to achieve quality in measurement. The main objectives are to explain the various steps involved in developing a method using a Quality by Design (QbD) approach for the development of analytical methods and to explain the implementation of Quality by Design (QbD) in the validation of analytical procedures. The advantages of applying Quality by Design (QbD) principles to analytical techniques include finding and minimizing sources of variability that could lead to poor method robustness and ensuring that the method meets the desired performance requirements over the product and method life cycle. The Analytical Quality by Design (AQbD) strategy is increasingly being adopted as it allows an early understanding of the method and guarantees the determination of a wider set of experimental conditions.
