Abstract

Estrogen-α (ER-α) is the main target for ER + therapy. Inhibition of ER-α is known to slow the proliferation of ER + breast cancer cells. Quinoline derivatives are known to have anticancer activity by inhibiting several types of receptors. It is not known whether quinoline can inhibit ER-α. This study aims to determine the interaction between ER-α with quinoline derivative compounds. Molecular docking of ER-α showed that quinine gave the most negative bond-free energy and the smallest inhibition constant, respectively -8.73 kcal/mol and 0.398 μM. These results provide predictions that quinine has activity as an ER-α inhibitor and has the potential to be developed in the treatment of ER + breast cancer. However, the affinity shown by quinine was lower than that of 4-hydroxytamoxifen, a potent inhibitor of ER-α.

Abstract

Observation of molecular docking results was generally performed by analyzing the docking score and the interacting amino acid residues separately either in tables or graphs. Sometimes it was not easy to rank the tested ligands’ docking results, especially if there were many ligands. This study aims to introduce a new way to analyze docking results with a two‐dimensional graph between the difference in docking score and the similarity of ligand‐receptor interactions. Molecular docking was performed with one reference ligand and several test ligands. The docking score difference was obtained between the test and the reference ligands as the graph’s x‐axis. Meanwhile, the y‐axis contains the similarity of ligand‐receptor interactions, obtained from the ratio of amino acid residues and the types of interactions between the test and reference ligands. Docking result analysis was more straightforward because two critical parameters were presented in one graph. This graph could be used to support the analysis of the docking results.

Abstract

Background:Acetaminophen (PCT) is known for its pro-oxidant properties, which neutralized by the presence of internal antioxidants such as glutathione (GSH). GSH has two forms: monomers and dimers, mainly distinguished by the presence of thiol group. Purpose:This study aims to see the difference in interaction between PCT with both forms of GSH. Method:Molecular docking was performed using Autodock Vina 1.1.2 on whole GSH surfaces. The main parameter used was the free energy of binding as affinity marker, as well as the position of PCT toward GSH. Result:The docking results show that PCT has a slightly higher affinity to the dimeric form of GSH than its monomeric form with the free energy of binding -2.7 kcal/mol and -2.2 kcal/mol, respectively. The interesting thing is the acetyl group of PCT is in a position far from the thiol group in the monomeric form of GSH, in contrast to its dimeric form. Conclusion:These results show that difference in affinity of PCT to both GSH forms is influenced by the position of the acetyl group against the thiol group of cysteine in GSH. The proximity of the pro-oxidant group to the thiol group leads to an increase in the affinity of the pro-oxidant to GSH.

Abstract

Proto-oncogene tyrosine-protein kinase Src is also known as simply Src is a tyrosine kinase protein which is one of the targets in various cancer therapies such as leukemia. Meanwhile, akar kuning (Arcangelisia flava) has gained significant attention as a medicinal plant that has a cytotoxic effect on various types of cancer cells. This study aims to determine the potential of secondary metabolites of akar kuning as Src inhibitors. Molecular docking was carried out using Autodock Vina 1.1.2 with 2HCK receptors, that quercetin and dasatinib were used as reference ligands. The docking results showed that the highest affinity was shown by berberine with a ΔG value of -9.0 kcal/mol, exceeded quercetin and dasatinib. However, the highest amino acid similarity to quercetin and dasatinib was produced by jatrorrhizine, with 93.33% and 73.91%, respectively. Interestingly, berberine is the ligand with the third-highest similarity after jatrorrhizine and palmatine, while jatrorrhizine has the second-highest affinity after berberine. The results concluded that the combination of berberine and jatrorrhizine is predicted to be optimally used as an Src inhibitor in cancer therapy.

Abstract

Previous research has shown that berberine, an alkaloid found in several plants such as akar kuning (Arcangelisia flava) shows the potential for inhibition of Human epidermal receptor-2 (HER2). Pharmacophore modification on the berberine was predicted could increase the affinity of berberine derivatives against HER2. The present study aims to determine the main pharmacophore of berberine with the highest influence towards berberine affinity against HER2. Molecular docking was performed on several modified pharmacophore of berberine against HER2. The docking results show that O atom at position number 23 has the most important influence on the berberine affinity towards HER2, where modification of O atom resulting in a decrease of berberine affinity. The highest affinity showed by derivate berberine-6 with the free energy of binding score and dissociation constant -10.80 kcal/mol and 12.17 nM, respectively. In contrast with other berberine derivatives, the berberine-6 derivate does not interact with the amino acid threonine at position 862. It provides a prediction that interaction of that amino acid potentially decrease the berberine activity towards active site of HER2. Further, derivate berberine-6 could be developed into HER2 inhibitor and should be potential to be developed as HER2-positive breast cancer therapy.

Abstract

This study discusses the development of small and medium micro enterprises (MSMEs) in Central Kalimantan with rattan woven craft industries being used as samples to represent other MSME sectors. The purpose of this study is to describe the improvement in the performance and strategy of the MSME group covering various aspects such as job training, capital support, equipment/technology assistance, and access to information and communication. The findings of this study indicate that the development of MSMEs carried out by regional governments in Central Kalimantan has gone in the right direction, with several factors still making improvements possible. Support in the form of training should be conducted regularly and scheduled with the topic of continuous training and productive participants. Aid in the form of equipment requires periodic evaluations, such as a reward-punishment system for business groups that have received various support to ensure the support provided is on target. Another strategy is to form the centre of the MSME industry in the Capital of the Province, to facilitate the access of tourists who just want to visit looking for typical Central Kalimantan souvenirs. The easiest way to do this now is to implement a movement of love for standard Central Kalimantan handicraft products to be displayed in various offices, offices, and government agencies as well as different infrastructure and public facilities.
