Abstract

Disinfectant products with excessive chlorine could be dangerous for health and need quality control. It is important to develop an analytical method for monitoring product quality. The main objective of this work is to develop an alternative method and evaluate the analytical performance of visible spectrophotometry for determining free chlorine in disinfectant products based on the Prussian blue decomposition process. The capability of chlorine to oxidize ferrous to ferric ions makes the Prussian blue generated by ferrosulfate and potassium ferricyanide is decomposed and measured by spectrophotometer. The formation of Prussian blue was improved by optimizing some reaction conditions and assessing incubation time. Linearity, analytical concentration range, precision, accuracy, detection limit, and quantitation limit parameters were among the examined analytical parameters. The results showed that the optimum concentration of ferrosulfate, potassium ferysianide, and hydrochloric acid for Prussian blue formation was 2.0 mmol L-1, 3.0 mmol L-1, and 0.5 mol L-1, respectively, with 15 minutes incubation time after chlorine addition. Analytical performance parameters seemed appropriate for routine analysis purposes. The developed method can also be applied as an alternative analytical method to determine the free chlorine concentration of disinfection products in the market.

Abstract

Background: Calophyllum soulattri Burm F. is widely utilized in traditional medicine. It is necessary to identify secondary metabolites from C. soulattri leaves to determine the pharmacologically active chemicals. Objective: This study aimed to screen the phytochemical content and purify the n-hexane fraction of C. soulattri leaves from Banyumas, Indonesia. Methods: The n-hexane fraction was macerated with methanol, followed by liquid-liquid fractionation with n-hexane. The n-hexane fraction was tested for flavonoids, triterpenoids/steroids, saponins, and phenols using the test tube method. In addition, the compounds were purified using column chromatography. The purified compound was identified by the Liebermann-Burchard reagent, which was compared with commercially available steroid drugs as reference. Results: Phytochemical analysis revealed that the n-hexane fraction of C. soulattri leaves contained secondary metabolites such as flavonoid, steroid, and phenol compounds. Analyses with the Liebermann-Burchard reagent indicated that the purified compound was potentially a steroid. Conclusion: The compound extracted from the n-hexane fraction of C. soulattri leaves was expected as a steroid.

Abstract

Breast cancer remains one of the most common cancers worldwide, with VEGFR-2 (KDR) playing a key role in tumor angiogenesis. Inhibiting VEGFR-2 is a promising therapeutic strategy. Natural compounds are increasingly studied for their potential to inhibit VEGFR-2. This study aims to assess the binding affinity of 11 natural compounds (andrographolide, alpha-mangostin, pinostrobin, pinocembrin, ethyl-p-methoxycinnamate (EPMS), xanthorrhizol, galangin, gamma-mangostin, curcumin, cinnamaldehyde, and alashanoid B) to the VEGFR-2 protein through molecular docking and Lipinski's rule analysis, identifying promising candidates for breast cancer treatment. Molecular docking simulations were performed for 11 compounds and sunitinib as a control, with binding energies and interactions analyzed. The compounds were also evaluated for drug-likeness using Lipinski’s rule of five. Curcumin showed the highest binding affinity to VEGFR-2 with a binding energy of -9.9 kcal/mol, surpassing sunitinib (-9.4 kcal/mol). Key interactions were observed with active site residues Cys919 and Asp1046. All tested compounds met the criteria for oral bioavailability per Lipinski’s rules. Curcumin demonstrates potential as a VEGFR-2 inhibitor due to its favorable binding affinity and drug-like properties. Enhancing curcumin’s bioavailability is recommended for effective therapeutic application.

Abstract

Kecombrang flower (Etlingera elatior) is widely used in traditional medicine and contains various metabolites. High-performance liquid chromatography (HPLC) fingerprinting can be employed as an analytical technique to comprehensively reveal the metabolite profile, while ultrasound-assisted extraction (UAE) was developed to optimize metabolite extraction. This study aims to determine the optimal extraction conditions for E. elatior and apply these conditions in HPLC fingerprinting. This study utilized central composite design (CCD) and response surface methodology (RSM) to optimize the extraction of E. elatior flowers, focusing on extraction time and the simplicia-to-solvent ratio. The optimal extraction results were applied to HPLC fingerprints of the flowers, leaves, and stems of E. elatior. The chromatograms were further analyzed using chemometric methods, namely principal component analysis (PCA), partial least squares discriminant analysis (PLSDA), and hierarchical cluster analysis (HCA) to classify and interpret the variability of metabolite profiles in different parts of E. elatior. The optimal UAE conditions were determined to be a time of 46 minutes and a simplicia-to-solvent ratio of 1:25 (g/mL). Chemometric analysis revealed that the samples were well clustered, which reflects the similarity of metabolites among them. The HCA further showed that the metabolite profile of E. elatior flowers is closely related to that of the stems.

Abstract

Breast cancer is a second deadly cancer after lung cancer worldwide. Progression of cancer is driven by mutated cancer drive gene such as ARHGAP35. This study aims to analyze the role of ARHGAP35 in the growth and development of breast cancer cells. ARHGAP35 expression level was analyzed using Oncomine (p-value<1E-4; gene rank top 10%). Overall survival (OS) and disease-free survival (DFS) were evaluated by using GEPIA (median cutoff; HR displayed with 95% CI). STRING was used for analyzing the protein-protein interaction network, while WEBGESTALT for KEGG pathway and gene ontology (GO) of ARHGAP35 and associated proteins and cBioPortal for gene mutation. ARHGAP35 was overexpressed in several types of breast cancer, namely invasive ductal breast carcinoma (IDC), invasive ductal and lobular breast carcinoma (IDLC), invasive lobular breast carcinoma (ILC), male breast carcinoma, and mixed ductal and lobular carcinoma (MDLC). High expression of ARHGAP35 had significantly lower OS (p=0.045) compared to low expression of ARHGAP35 and the difference in DFS was not significant (p=0.98). ARHGAP35 interacted with RHOA, RHOB, RHOC, RHOD, RASA1, RND1, RAC1, CDC42, FYN and SRC. KEGG pathway and GO analysis showed that these proteins are highly involved in actin-based processes through adherent junction, axon guidance, focal adhesion, regulation of actin cytoskeleton, and tight junction. Mutation rate analysis showed 34 missense, 29 truncating, 3 fusion, and 1 in frame on ARHGAP35. Taken together, ARHGAP35 may involve in the growth and development of breast cancer through regulation of actin cytoskeleton pathway.Keywords: ARHGAP35, breast cancer, KEGG pathway, mutation rate, actin cytoskeleton.

Abstract

Chalcones, a class of naturally occurring compounds, exhibit a broad spectrum of biological activities, including anticancer properties. In this study, a series of methoxylated chalcones were synthesized via Claisen-Schmidt condensation and evaluated for cytotoxic activity against breast cancer MCF-7 and prostate cancer DU-145 cell lines. The synthetic route involved Claisen-Schmidt condensation, leading to various methoxy-substituted chalcone derivatives. The structures of the synthesized chalcones were confirmed through NMR and mass spectrometry. Cytotoxicity was assessed using the PrestoBlue assay, with 4-bromochalcone (compound 2) displaying the highest cytotoxic activity against MCF-7 cancer cell lines (IC50 = 26.99 µM). These results indicate that methoxylated chalcones hold promise as potential lead compounds for the development of new anticancer agents targeting breast and prostate cancer.
