Abstract

Breast cancer is the most common cancer among women and a major cause of cancer-related death worldwide, including Indonesia. Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer, characterized by high mortality and resistance to standard treatments. Cancer stem cells (CSCs) is known to be a key factor of drug resistance in TNBC, mediated by the signal tranducer and activator of transcription factor 3 (STAT3). This study aims to explore the bioactive compounds from Indonesian’s natural product which potentially target CSCs by inhibiting STAT3. We used in silico methods, consist of literature review, followed by selection of promising compounds, ADMET analysis and selection using Lipinski’s rules, and molecular docking simulation. Our results found curcumin, quercetin, α-mangostin, gingerol, and rocalglamide as the bioactive candidates which target CSCs. ADMET testing showed that only curcumin, quercetin, and gingerol meet the Lipinski’s criteria. The molecular docking results showed that quercetin exhibited the strongest binding affinity (-8.3 kcal/mol) compared to curcumin (-6.9 kcal/mol) and gingerol (-5.9 kcal/mol). The results indicate that quercetin binds effectively at the active site of STAT3. The findings suggest that quercetin has potential as a STAT3 inhibitor. Further research is needed to determine the significant efficacy and potential as an anticancer.

Abstract

This study aims to determine the unconfined compressive strength of recycled materials based on variations in cement content of 1%, 3%, and 5%, as well as the percentage of emulsified asphalt. This study is urgently needed because the massive development of road infrastructure drives an increase in the need for road materials. Utilization of recycled waste from existing asphalt layers and foundation layers is an alternative sustainable and environmentally friendly material. Reusing this material is more efficient if the road damage has not reached the structural stage. Testing in the study was conducted experimentally at the Road Materials Center Laboratory, Bandung, using materials from existing asphalt layers and foundations. Testing includes physical analysis of the material, compaction to determine the optimum water content and maximum dry density, and unconfined compressive strength. The results showed that the unconfined compressive strength with cement content of 1%, 3%, and 5% were 0.70 MPa, 1.70 MPa, and 2.09 MPa, respectively, with primary displacement values ​​of 20 mm, 25.8 mm, and 24.7 mm. Meanwhile, the residual strength value decreased with increasing cement content, namely 76.3%, 66.3%, and 64.3%.
