Sintesis Dan Studi Molecular Docking Senyawa 4-(1-(4-Fluorofenil)-5-(3-Metoksifenil)-4,5-Dihidro-1h-Pirazol-3-Il) Fenol Sebagai Antikanker Payudara
Pyrazoline has two nitrogen atoms adjacent to each other in its ring and possess only one endocyclic double bond. This compound has bioactivity such as antibacterial, antitumor, antidiabetic, anti-inflammatory and anticancer and others. Pyrazoline, which has functional groups such as chloro, fluoro, bromo, and methoxy, has various pharmacological activities, such as being an anticancer agent. The pyrazoline compound 4-(1-(4-Fluorophenyl)-5-(3-Methoxyphenyl)-4,5-Dihydro-1H-Pirazol-3-yl) phenol and named as P3OME-4OH-4F has been successfully synthesized through three stages reaction. The first stage is the formation of the chalcone compound (10) through the Claisen-Schmidt condensation reaction, the second stage is the formation of the hydrazine compound (13) through diazotation and reduction reactions and the third stage is the formation of the P3OME-4OH-4F compound (14) through the cyclization reaction with each yields of 54%, 84% and 52%. The purity analysis of each synthesized compound was conducted using techniques such as thin-layer chromatography (TLC), determination of melting points, and high-performance liquid chromatography (HPLC). Based on spectroscopy data of UV, FTIR, LC-MS, 1H-NMR, and 13C-NMR, the P3OME-4OH-4F compound was confirmed to match the intended structure. The P3OME-4OH-4F compound showed remarkable efficacy in in-silico bioactivity analysis through the molecular docking method as an inhibitor of alpha-estrogen protein (ER-α). It exhibited more potent values for binding free energy (ΔG) and inhibition constant (Ki) than its positive control which the values were -9,9 kcal/mol and 0,0548 µM for P3OME-4OH-4F, whereas they were -9,3 kcal/mol and 0,151 µM for 4-hydroxytamoxifen.
