      Abstract
      Kanker merupakan salah satu jenis penyakit berbahaya yang mengalami peningkatan kasus setiap tahunnya. Radikal bebas merupakan penyebab mutasi gen yang dapat memicu kanker. Kanker akan berkembang tanpa terkendali karena terjadinya disregulasi siklus sel dan adanya senyawa pemicu proliferasi sel serta penghambat proses apoptosis. Pengobatan kanker dilakukan dengan memberikan inhibitor cyclin dependent kinase2 (CDK2) dan cyclooxygenase-2 (COX-2) untuk menghambat perkembangan kanker, serta inhibitor lipoxygenase (LOX) untuk menghambat pembentukan radikal bebas. Tanaman temu ireng diketahui memiliki potensi sebagai antioksidan dan antikanker. Penelitian ini bertujuan mengetahui interaksi molekuler antara senyawa dominan ekstrak etanol temu ireng dengan CDK2, COX-2, dan LOX sebagai reseptor. Jenis interaksi ligan dengan reseptor ditentukan melalui parameter energi afinitas (ΔG), konstanta inhibisi (Ki), jenis interaksi dan persentase binding site similarity (%BSS). Hasil penelitian menunjukkan bahwa senyawa uji gajutsulacton A memiliki potensi terbaik dalam menghambat CDK2. Senyawa uji cucumenol berpotensi sebagai inhibitor COX-2 tetapi tidak terdapat senyawa yang dapat menghambat LOX dengan baik sebagai antioksidan.
       
      Cancer is one type of dangerous disease that is increasing every year. Free radicals are the cause of gene mutations which can lead to cancer. Cancer will develop uncontrollably due to the dysregulation of the cell cycle and the presence of compounds which trigger cell proliferation and inhibit the process of apoptosis. Cancer treatment is carried out by giving cyclin-dependent kinase2 (CDK2) and cyclooxygenase-2 (COX-2) inhibitor drugs to inhibit cancer development, as well as lipoxygenase (LOX) inhibitor drugs for the formation of free radicals. The temu ireng plant is known to have the potential as an antioxidant and anticancer. This study aims to determine the molecular interaction between the dominant compound of temu ireng ethanol extract with CDK2, COX-2, and LOX receptors. The type of ligand interaction with the receptor was determined through the parameters of affinity energy (ΔG), inhibition constant (Ki), type of interaction, and percentage of binding site similarity (%BSS). The results showed that the test compound gajutsulacton A had the best potential in inhibiting CDK2. The test compound cucumenol may be a COX-2 inhibitor and there are no compounds that can inhibit LOX well as an antioxidant.
