Abstract

Breast cancer is one of the deathliest cancer diseases for women, with high mortality cases. Since breast cancer cells overexpressed HER2 receptors, a computerized structure-based screening was conducted to identify potential HER2 inhibitors as an anti-breast cancer agent. This method can investigate the potency of proposed compounds as potential protein inhibitors. Researchers were interested in studying some synthetic macromolecules, i.e., allyl-modified calix[4]resorcinarenes, through in silico studies as HER2 inhibitors using molecular docking studies. Prospective protein-ligand complexes for HER2 inhibition were further investigated by molecular dynamics simulations for 200 ns on different binding pockets. The allyloxycalix[4]resorcinarene derivative (5A) was identified as the most potential HER2 inhibitor through a computational approach, including molecular docking studies and molecular dynamics simulations. The HER2-5A complex was relatively stable during the 200 ns molecular dynamics run. In addition, the hydrogen bonds formed between blind docking and molecular dynamics simulations are almost unchanged for the HER2-5A complex. The HER2-5A formed with two crucial amino acid residues, i.e., Asp845 and Asn850. Moreover, the data of the molecular dynamics simulations of compounds 5A and 2A demonstrate the stability of both complexes in different binding sites of HER2. These computational results are preliminary data for further synthesis and in vitro evaluation.

Abstract

Indonesia's rich flora has long been used in traditional herbal medicine, and scientific research is now confirming the health benefits of these plants. Among them, Papuan Red Fruit is gaining attention for its potential in treating various ailments, including COVID-19, due to its antioxidant and antibacterial properties. This study focuses on using in silico methods to investigate how Papuan Red Fruit might inhibit COVID-19, specifically by targeting the papain-like protease (PLpro), a key protein in viral replication. Molecular docking and molecular dynamics (MD) simulations were used to assess the binding affinity and stability of compounds from the fruit. The compound quercetin 3'-glucoside showed the lowest binding energy, indicating strong interactions with PLpro. MD simulations at 300 K for 100 ns confirmed the stability of the quercetin 3'-glucoside-PLpro complex, revealing hydrogen bonds with residues like GLN169. The simulations showed an average delta RMSD of 0.2702 Å, indicating the complex's stability. Overall, this research highlights the potential of Papuan Red Fruit as a natural treatment for COVID-19, opening the door for further studies in drug development.

Abstract

Tanaman Obat Keluarga (TOGA) are a valuable local resource that can be cultivated as an alternative approach to maintaining family health independently. However, public knowledge and practical skills related to the types of TOGA and proper cultivation techniques remain limited. This community service program aimed to improve community awareness and skills in cultivating TOGA within household environments. The program was implemented through socialization activities using educational pamphlets, instructional videos, and interactive door-to-door discussions across three target areas: urban settlements, rural villages, and residential complexes. The results demonstrated a significant improvement in participants' knowledge of TOGA varieties. Before the program, only about 40% of participants were familiar with more than five types of TOGA, which increased to 85% after the socialization activities. Furthermore, over 75% of participants could correctly describe the basic steps of TOGA cultivation, and approximately 60% of households had already begun planting TOGA in their yards or using simple containers such as pots and polybags. Evaluation also revealed strong enthusiasm and active involvement, as evidenced by participants' engagement in discussions and their initiative to form small groups for continuous TOGA development. In conclusion, this community service activity successfully enhanced participants' knowledge, skills, and motivation to cultivate TOGA. The program is expected to contribute to long-term community self-reliance in herbal-based health maintenance and foster the establishment of sustainable TOGA communities within local neighborhoods.
