Abstract

Background: Nowadays, a lot of new active substances as anticancer agents have been developed. One of the protein targets of anticancer is selective cyclooxygenase-2 (COX-2). Selective COX-2 is the regulator of cell proliferation. Objective: In this research, quinazoline derivatives were used to design the anticancer agent through a selective COX-2 inhibition. The potential activity of quinazoline derivatives could be increased by substitution in position 2 and 3 of quinazolinone. Molecular docking of selective COX-2 inhibition was required to predict their antiproliferation activity. Methods: The molecular docking of quinazoline derivatives was carried out using Molegro Virtual Docker (MVD) Ver.5.5. Twenty-one of quinazoline derivatives were docked into selective COX-2 with PDB code 3LN1. The interaction was evaluated based on the re-ranked score comparison between quinazoline derivatives with co-crystallized ligand CEL_682. Celecoxib was used as the reference to this research. Results: The result indicated that 18 of 21 quinazoline derivatives showed the approximately re-ranked score -131.508 to -108.418 kcal/mol. Eight of these 18 new quinazoline derivatives have re-ranked score better than Celecoxib. Conclusions: In conclusion, 8 of the new quinazoline derivatives are feasible to be synthesize and performed their in vitro evaluation.

Abstract

Background: Synthetic curcumin analogs have been widely studied due to their pharmacological activity. One of the curcumin analog compounds, namely 2,5-bis(4-hydroxy-3-methoxybenzylidene)cyclopentanone (HM-BCP), which has more potent anti-inflammatory activity than curcumin.. In the synthesis process, the presence of the OH-phenolic group is still a problem to maximize the reaction condition. The use of strong base catalysts may cause unwanted side reactions with the phenolic OH group present in the substrate. Therefore, barium hydroxide was used as the catalyst because it has lower basicity than NaOH, which is commonly used in this reaction. Objective: This study aims to synthesize HM-BCP using Ba(OH)2.8H2O as a catalyst in several concentrations. The reaction was assisted by microwave irradiation. Methods: Synthesis of HM-BCP from cyclopentanone and vanillin via Claisen-Schmidt condensation in alkalis condition. Cyclopentanone, vanillin, and Ba(OH)₂·8H₂O were mixed for 15 min, followed by microwave irradiation (480 W, 10 min). The reaction mixture was stirred for 5 min after each minute of irradiation. The reaction product was analyzed by TLC to determine the area percent ratio of the starting material (vanillin), and HM-BCP. The purity of the synthesized products were tested using TLC and melting point determination, while structure identification by IR and H-NMR spectroscopic methods. Results: The use of 2–4 molEq of Ba(OH)₂ as the catalyst in the synthesis of HM-BCP produced relative percentage areas of 11.4%, 15.8%, and 20.9%, respectively. Conclusion: Barium hydroxide has been shown to act as a catalyst in the synthesis of HM-BCP via Claisen-Schmidt condensation but optimization of reaction conditions is needed.
