Anti-breast cancer bioactive compounds and in-silico molecular prediction of Crassostrea angulata (Lamarck, 1819): Prediksi senyawa bioaktif antikanker payudara dan molekuler in-silico Crassostrea angulata (Lamarck, 1819)

Abstract

Kanker payudara merupakan penyebab kematian kedua terbanyak di Indonesia. Bioprospeksi senyawa bioaktif dari organisme laut diharapkan dapat menjadi salah satu solusi pencegahan kanker payudara. Crassostrea angulata merupakan salah satu spesies tiram laut yang biasa dikonsumsi dan memiliki sejarah etnomedik di kalangan masyarakat Indonesia. Penelitian ini bertujuan untuk mengevaluasi potensi senyawa bioaktif antikanker dari ekstrak metanol C. angulata menggunakan analisis in-silico. Identifikasi senyawa aktif C. angulata menggunakan LC-HRMS melalui pendekatan molecular docking dengan mengombinasikan program-program KNApSAcK, CLC-Pred, SEA, STRING, PubChem, UniProt, PyMOL, PyRx, and PoseView. Hasil penelitian menunjukkan 12 senyawa aktif antikanker pada C. angulata, namun hanya 2 senyawa antikanker payudara (Flufenamic Acid, FA dan Hymenamide C, HC). Hasil molecular docking menunjukkan bahwa binding affinity yang kuat antara senyawa aktif Flufenamic Acid (FA) dengan protein target kanker payudara (CSF1R, PLK4, MKNK2, dan ABL1) dan senyawa Hymenamide C (HC) dengan protein target kanker payudara (GRB2 dan OXTR). Senyawa bioaktif FA menunjukkan nilai RMSD yang lebih rendah (mendekati 0Å) dengan ligan asli dari masing-masing protein target. FA memiliki potensi sebagai senyawa antikanker payudara yang lebih baik dari HC. Senyawa FA dan HC berpotensi sebagai penghambat protein target kanker payudara, namun masih memerlukan penelitian lebih lanjut terutama untuk penggunaan senyawa tersebut pada manusia.Breast cancer is the second leading cause of death in Indonesia. Bioprospecting bioactive compounds from marine organisms is expected to be one of the solutions for breast cancer prevention. Crassostrea angulata is one of the species of sea oysters that is commonly consumed, and it has an ethnomedical history among Indonesian people for decades. The aim of this study is to use in silico analysis to find out how well bioactive compounds from C. angulata methanol extract can fight breast cancer. To find compounds that work in C. angulata, LC-HRMS and a molecular docking method that mixed KNApSAcK, CLC-Pred, SEA, STRING, PubChem, UniProt, PyMOL, PyRx, and PoseView were used. The result showed at least 12 active anti-cancer compounds in C. angulata, but only 2 of them are anti-breast cancer compounds (Flufenamic Acid, FA, and Hymenamide C, HC). Molecular docking results showed a strong binding affinity between the active compound Flufenamic Acid (FA) with its breast cancer target proteins (CSF1R, PLK4, MKNK2, and ABL1) and the Hymenamide-C (HC) compound with its breast cancer target proteins (GRB2 and OXTR). FA bioactive compounds also showed lower RMSD values (close to 0 Å) with native ligands for each target protein. FA has the potential to be a better anti-breast cancer compound than HC. However, these two compounds still hold potential as inhibitors of breast cancer target proteins, and further research on marine bio-natural products for human use is necessary
