Abstract

Degenerative disease caused by decreasing organ function in old people has become the biggest death cause in the world. This aging process marked by senescence activity. An anti-aging agent from the medicinal plant has high potency to be developed, such as pumpkin seed (Cucurbita moschata) which contain tocopherol as antioxidant. The aim of this study is to investigate the anti-aging effect of pumpkin seed extract (PSE) on NIH 3T3 fibroblast normal cell induced by doxorubicin. This anti-aging effect was observed using MTT assay continued by SA- βgal (Senescence-Associated Beta-Galactosidase) activity detection test. The stability of  molecular interaction between tocopherol and doxorubicin to CYP 3A4 as the oxidase enzyme was conducted using molecular docking. Based on in vitro test, PSE is not cytotoxic to NIH 3T3. PSE at the dose of 100,200,400, and 800 μg/mL decreased % cell senescence by 2,77; 4,5; 6; and 18 times respectively. Meanwhile, in silico test indicated that tocopherol (-107,409) has a higher interaction to CYP 3A4 compared to doxorubicin (-70,52). Both compounds have a similar binding site in Leu 364; Phe 435; Pro 434; Cys 442; Ile 369; Thr 309; dan Ala 305. The overall result of this study showed that PSE has anti-aging effect by decreasing SA- βgal activity. This anti-aging activity possibly due to the interaction between tocopherol to CYP 3A4 based on molecular docking.Keywords: anti-aging, Cucurbita moschata, tocopherol, SA-βgal, molecular docking

Abstract

Cyclophosphamide (CPA) is an effective chemotherapeutic agent, but has side effect, causing DNA damage (genotoxic). Papaya leaf (Carica papaya L.) is known has flavonoid compound, quercetin. Quercetin is known has DNA protecting effect (antigenotoxic effect) by metabolism modulation. Thus, the aim of this research is to investigate the antigenotoxic effect of ethanolic extract of papaya (Carica papaya L.) leaf (EEPL) on CPA induced mice. The antigenotoxic effect was evaluated by mammalian in vivo micronucleus test. EEPL was orally administered as single treatment at dose 1000 mg/kgBW and in combination with CPA 50 mg/kgBW at dose 250 mg/kgBW; 500 mg/kgBW; and 1000 mg/kgBW. Molecular docking using PLANTS on CYP 3A4 was performed to explore the antigenotoxic effect mechanism. The three different combination dose of EEPL with CPA significantly (P<0.05) decreased the amount of micronucleated polychromatic erytrhocyte (MNPCE)/1000 polychromatic erythrocyte (PCE) and also increased % PCE/(PCE+normochromatic erythrocyte (NCE)), compared with single dose of CPA. Nevertheless, the antigenotoxic effect wasn’t significant compared with each combination dose. The docking score result showed quercetin (-82,41) has more potent interaction to CYP 3A4 than cyclophosphamide (-70,16) and both of them has similar active site at amino acid residue Ile 369 and Thr 309. The results obtained indicated that EEPL at dose 250 mg/KgBB is the optimal dose as antigenotoxic agent by interaction between quercetin with CYP 3A4 based on molecular docking.Keywords: antigenotoxic, Carica papaya L., MNPCE, in vivo
