Abstract

Cancer therapy through conventional chemotherapy has been widely applied; however, one of the main disadvantages of chemotherapy is the non-selective targeting of cancer cells which causes various adverse side effects. The development of drug delivery agents that are more selective and effective in cancer therapy needs to be performed so that the drugs have a therapeutic effect and minimize side effects. In this study, the compound C-phenylcalyx[4]resorcinarene epoxide (CFKRE) has acted as a drug delivery agent because it can form host complex interactions with ligands. The CFKRE compound was synthesized through two reaction steps: the condensation and alkylation reactions of the epoxide. The structure was analyzed using FTIR, 1H-, and 13C-NMR spectrophotometers and then tested for in vitro cytotoxicity using the MTT assay. The results showed that 70% yield of CFKRE was obtained. Molecular docking analysis of CFKRE compounds against PDGFR and EGFR proteins showed high binding energy compared to conventional chemotherapeutic agents. Molecular dynamic studies showed that CFKRE compounds could form a host-ligand complex with a −350.4 kcal/mol binding energy. Cytotoxic assay of CFKRE compound against MCF-7 breast cancer cells and Vero cells gave IC50 values of 4.04 and 29.59 μg/mL, respectively. These results indicated that CFKRE compounds are not toxic and have the potential to be utilized as new candidates for drug delivery agents.

Abstract

Telah dilakukan sintesis senyawa antara 3-(3,4-dimetoksifenil) propanal dalam pembuatan turunan antibiotik C-9154 sebagai upaya perluasan poemanfaatan minyak kayu cengkeh. Eugenol merupakan komponen utama minyak daun cengkeh yang dapat diisolasi menggunakan pelarut natrium hidroksida. Pemanfaatan senyawa ini masih sangat terbatas, sehingga perlu dilakukan upaya pengubahan eugenol menjadi senyawa turunannya yang lebih berdaya guna. Salah satunya, eugenol dapat diubah menjadi senyawa 3-(3,4-dimetoksifenil)-propanal, senyawa tersebut digunakan sebagai bahan untuk mensintesis senyawa turunan antibiotik C-9154. Dalam penelitian ini digunakan bahan dasar metileugenol hasil metilasi eugenol. Reaksi hidroborasi metileugenol menggunakan reagen H3B:dietileter secara in situ dengan mereaksikan NaBH4 dan BF3:dietileterat pada suhu 0 „aC dan kondisi inert yang dibuat dengan mengalirkan gas nitrogen ke dalam sistem. Hasil reaksi dianalisis menggunakan metode spektroskopi inframerah dan spektroskopi massa. Oksidasi 3-(3,4-dimetoksifenil)-1-propanol menjadi 3-(3,4-dimetoksifenil)-propanal menggunakan oksidator piridinium klorokromat menggunakan pelarut diklorometan, dan direfluks selama 3 jam pada suhu reaksi 30 oC. Hasil reaksi dianalisis mengunakan metode spektroskopi inframerah, spektroskopi massa dan 1H-NMR. Hasil reaksi hidroborasi metileugenol merupakan cairan berwarna kekuningan dengan rendemen 81,29%, analisis spektra inframerah dan spektroskopi massa menunjukkan senyawa hasil adalah 3-(3,4-dimetoksifenil)-propanol. Hasil reaksi oksidasi 3 -(3,4-dimetoksifenil)-propanol didapat cairan berwarna coklat kehitaman dengan rendemen sebesar 71,3 %. Hasil analisis menunjukkan bahwa senyawa hasil adalah 3-(3,4-dimetoksifenil)-propanal. Selanjutnya senyawa ini dapat digunakan sebagai bahan dasar sintesis turunan antibiotic C-9154.Kata kunci: Eugenol, 3-(3,4-dimetoksifenil)-propanal dan turunan antibiotik C-9154

Abstract

Urea levels in urine play an important parameter in diagnosing bodily conditions through liver and kidney examinations. The typical reagent for detecting urea content in urine is para-dimethylaminobenzaldehyde (pDMAB). However, it has a drawback related to the instability of color in the resulting Schiff base compound (pDMAB-urea). In this study, the synthesized vanillin compound derived from clove oil serves as the foundational material for a urea chemosensor based on the colorimetric concept. The synthesized vanillin was characterized using FTIR, GC-MS, and 1H-NMR. The formulation of the vanillin compound as a sensor was conducted by assessing the suitable solvent, determining the optimal mass of vanillin, and evaluating the acid-base conditions of the sensor formulation system both qualitatively and quantitatively. Subsequently, the most effective formulation was selected for detecting urea in urine samples. The synthesis of vanillin yielded a purity level of 95%. The optimal formulation was obtained at an optimum mass of vanilla of 0.75 g in 50 mL of 96% ethanol and 10 mL of 10% NaOH. The color change in the sample was from colorless to greenish yellow (436 nm). The vanillin obtained was applied to urine samples with the best results at a sample dilution level of 10,000×.
