Introduction

Aging is an inevitable process. However, prevention of age-related diseases that often follows can be done by modifying its main risk factors, including inflammation. One approach that can be used is to utilize plants that are rich in antioxidants. Rosella (Hibiscus sabdariffa Linn.), has been shown to have high antioxidant activity. However, there is currently no specific study that assesses its impact on a specific aging biomarker like Sirtuin 1.

Method:

This in vivo experimental study was conducted on 18 male Sprague Dawley rats that were randomly divided into 3 groups: control (K) which were normal young rats that are fed with standard feed; Accelerated Aging (AA) which were fed high fat feed and D-galactose; and Hibiscus sabdariffa Linn. (HSL) which were fed high fat feed, D-galactose, and the ethanol extract of H. sabdariffa flowers at a dose of 400 mg/KgBW. The treatment was carried out for 6 weeks. At the end of the study, SIRT1 levels were measured using a standard ELISA kit.

Results:

The difference in mean SIRT1 levels obtained between groups was not statistically significant.

Conclusion:

HSL extract has not yet been able to increase SIRT1 levels."

"Pendahuluan: Data Susenas tahun 2022 yang dikeluarkan oleh Badan Pusat Statistik (BPS) mencatat bahwa 10,48% penduduk Indonesia adalah lansia dengan 2 dari 5 lansia memiliki keluhan kesehatan. Hal ini bisa disebabkan karena banyaknya faktor ekstrinstik maupun intrinsik yang menyebabkan kerusakan seluler sehingga menginduksi protein p53 untuk melakukan cellular senescence. Senyawa thymol, carvacrol, dan flavonoid (quercetin, luteolin, apigenin, rutin, eriodictyol) dalam ekstrak tanaman Plectranthus amboinicus yang kaya akan antioksidan dipercaya dapat menghambat proses cellular senescence sehingga dapat menekan proses penuaan. Dengan itu, tujuan dari penelitian ini adalah untuk mengetahui interaksi antara komponen ligan pada senyawa aktif thymol, carvacrol, dan flavonoid yang terkandung dalam Plectranthus amboinicus dengan protein target p53 yang berkaitan dengan aktivitas cellular senescence pada proses penuaan. Metode: Studi in silico melalui molecular docking (penambatan molekuler) untuk menguji interaksi molekuler dari ligan senyawa thymol, carvacrol, dan flavonoid (quercetin, luteolin, apigenin, rutin, eriodictyol) dari tanaman Plectranthus amboinicus terhadap reseptor protein target p53 yang bertanggung jawab dalam proses cellular senescence. Hasil interaksi yang didapat merupakan sebuah histogram yang akan dianalisis dan diinterpretasikan untuk mengetahui afinitas ikatan (binding affinity) dari interaksi yang terjadi. Hasil: Terjadi interaksi antara ligan senyawa thymol, carvacrol, dan flavonoid (quercetin, luteolin, apigenin, rutin, eriodictyol) dari tanaman Plectranthus amboinicus terhadap reseptor protein target p53. Kesimpulan: Plectranthus amboinicus berpotensi menjadi agen anti-aging yang dapat menghambat dan memperlambat proses dari penuaan melalui studi in silico. Akan tetapi, perlu dilakukan penelitian lebih lanjut mengenai mengenai sifat-sifat dari Plectranthus amboinicus untuk mengetahui potensi tanaman ini terhadap tubuh manusia yang belum diketahui.

Introduction: The 2022 Susenas data stated by the Central Statistics Agency (BPS) notes that 10.48% of Indonesia’s population are elderly with 2 out of 5 having health complaints. This could be due to the many extrinsic and intrinsic factors that causes cellular damage thereby inducing the p53 protein to perform cellular senescence. Compounds of thymol, carvacrol, and flavonoids (quercetin, luteolin, apigenin, rutin, eriodictyol) from the extract of the Plectranthus amboinicus plant which are rich in antioxidants are believed to have the potential to inhibit the cellular senescence process so as to suppress the aging process. The purpose of this research is to investigate the interaction between the ligand of thymol, carvacrol, and flavonoid compounds from Plectranthus amboinicus with the p53 target protein which is associated with cellular senescence activity in the aging procress. Methods: In silico study through molecular docking to examine the molecular interactions of the ligands of thymol, carvacrol, and flavonoids (quercetin, luteolin, apigenin, rutin, eriodictyol) from the Plectranthus amboinicus plant against the target protein receptor p53 which is responsible for the process of cellular senescence. The interaction results obtained is a histogram which will be analyzed and interpreted to determine the binding affinity of the interactions that occured. Results: Interactions existed between the ligands of thymol, carvacrol, and flavonoids (quercetin, luteolin, apigenin, rutin, eriodictyol) from the Plectranthus amboinicus plant against the target protein receptor p53. Conclusion: Plectranthus amboinicus has the potential to be an anti-aging agent that can inhibit and slow down the process of aging through in silico studies. However, it is necessary to carry out further research regarding the properties of Plectranthus amboinicus to determine the unknown potential of this plant to the human body.

"Pendahuluan. Proses penuaan merupakan kondisi gangguan fungsi akibat penurunan integritas fisiologis yang dapat menjadi faktor risiko penyakit utama lain. Proses penuaan diakibatkan radikal bebas dan kondisi stres oksidatif sehingga dapat mempercepat proses penuaan. Kondisi ini menyebabkan peningkatan mediator proinflamasi, penurunan kognisi dan kekuatan otot. Berdasarkan studi, Acalypha indica Linn (AI) menunjukkan efek antioksidan dan antiinflamasi. Ekstrak tanaman herbal AI juga diketahui dapat menekan sitokin proinflamasi, meningkatkan kognisi dan kekuatan otot. Penelitian ini dilakukan untuk mengetahui pengaruh AI dalam proses penuaan melalui perlakuan terhadap tikus Sprague-Dawley (SD) tua. Metode. Tikus SD terdiri dari Tikus SD tua (n=21) dan Tikus SD muda sebagai pembanding (n=6). Tikus SD tua dibagi menjadi tiga kelompok, yaitu kelompok perlakuan (ekstrak etanol AI 250 mg/kg berat badan), kontrol negatif, dan kontrol positif (vitamin E 6 IU). Kognisi tikus SD diuji menggunakan metode Y-maze sebelum dan selama perlakuan melalui uji setiap minggu. Perlakuan diberikan tikus selama 28 hari. Pada hari ke-29, kekuatan otot tikus dilakukan dengan metode grip test, setelah itu tikus diterminasi dan dilakukan pengukuran kadar interleukin-6 darah menggunakan enzyme-linked immunosorbent assay (ELISA). Hasil. Ditemukan penurunan kadar IL-6 darah (p=0,02) dan peningkatan kekuatan otot (p=0,032) yang signifikan pada kelompok perlakuan (AI) dibandingkan dengan kontrol negatif. Namun, tidak memperlihatkan perbedaan yang signifikan pada kognisi tikus (p>0,05). Kesimpulan. Ekstrak etanol AI dapat menurunkan kadar IL-6 darah dan meningkatkan kekuatan otot tikus SD tua, tetapi tidak memberikan efek yang signifikan terhadap kognisi tikus SD tua. Dibutuhkan penelitian lanjutan untuk melihat lebih jauh dan mendalam mengenai potensi AI sebagai agen antipenuaan.

Objectives. Aging is a condition of impaired function due to the decrease of physiological" "integrity that can be a risk factor for another disease. Aging process is caused by free radicals and oxidative stress that can increase proinflammatory mediators, such as interleukin-6. Acalypha indica Linn (AI), is widely used as a herbal medicine. Studies have shown that AI have antioxidant and antiinflammatory effects and known to suppress proinflammatory cytokines, improve cognition and muscle strength. We aimed to study the effects of AI in the aging process through treatment on aged Sprague-Dawley (SD) rats.

Methods. Old (n=21) and young SD rats as a comparison group (n=6). Aged rats were divided into treatment group (AI ethanolic extract 250mg/kg bodyweight), negative control, and positive control (6IU vitamin E). SD rats cognition was tested (Y-maze method) before and during treatment every week. Treatment was given for 28 days. On the 29th day, muscle strength was tested (grip test). SD rats were terminated and measured for its blood interleukin-6 levels using enzyme-linked immunosorbent assay (ELISA).

Results. Decrease in blood IL-6 levels (p=0.02) and an increase in muscle strength (p=0.032) significantly was found in the treatment group (AI) compared to negative control. Statistics did not show significant differences in rats cognition (p>0.05).

Conclusions. AI ethanolic extracts can reduce blood IL-6 levels and increase muscle strength on aged SD rats, but did not have a significant effect on its cognition. More research is needed to look further about the potential of AI as an antiaging agent."
