Abstract
Katekin merupakan senyawa polifenol yang memiliki aktivitas biologis, termasuk sebagai antikanker. Namun, keterbatasan sifat fisikokimia katekin seperti kelarutan dan stabilitas dapat menghambat aplikasinya. Penelitian ini bertujuan untuk melakukan derivatisasi katekin melalui reaksi esterifikasi dengan asam salisilat menggunakan metode steglich serta menguji aktivitas antikankernya secara in silico. Esterifikasi dilakukan dengan pereaksi DCC (N,Ndisikloheksilkarbodiimida) sebagai aktivator dan DMAP (4-dimetilaminopiridin) sebagai katalis. Hasil reaksi dimonitor dengan Kromatografi Lapis Tipis (KLT), dan identifikasi senyawa dilakukan menggunakan spektrofotometri uv-vis dan FTIR. Analisis FTIR menunjukkan terbentuknya gugus C=O ester pada bilangan gelombang 1720–1740 cm⁻¹ yang mengindikasikan keberhasilan esterifikasi, dengan kerangka aromatik flavonoid tetap terjaga. Hasil docking molekuler menunjukkan bahwa pada dua turunan ester katekin salisilat memiliki afinitas yang baik terhadap protein target, pada kedua target 3ERT dan 1QKM memiliki dua jenis ikatan sehingga membentuk kompleks yang kuat dan stabil. Hal ini menunjukkan bahwa ester katekin salisilat berpotensi memiliki aktivitas antikanker lebih baik dibandingkan katekin murni. Penelitian ini memberikan dasar pengembangan lebih lanjut melalui uji aktivitas in vitro maupun in vivo. ------ Catechins are polyphenolic compounds that have biological activity, including anticancer activity. However, the limitations of the physicochemical properties of catechins, such as solubility and stability, can hinder their application. This study aims to derivatize catechins through esterification reactions with salicylic acid using the Steglich method and to test their anticancer activity in silico. Esterification was carried out with DCC (N,N-dicyclohexylcarbodiimide) as an activator and DMAP (4-dimethylaminopyridine) as a catalyst. The reaction results were monitored by Thin Layer Chromatography (TLC), and compound identification was performed using UV-Vis spectrophotometry and FTIR. FTIR analysis showed the formation of C=O ester groups at a wavelength of 1720–1740 cm⁻¹, indicating successful esterification, with the flavonoid aromatic framework remaining intact. Molecular docking results showed that the two catechin salicylate ester derivatives had good affinity for the target protein. Both 3ERT and 1QKM had two types of bonds, forming a strong and stable complex. This indicates that catechin salicylate esters have the potential to have better anticancer activity than pure catechin. This study provides a basis for further development through in vitro and in vivo activity testing.
