Clitorin ameliorates western diet-induced hepatic steatosis by regulating lipogenesis and fatty acid oxidation in vivo and in vitro
Sci Rep 2022 Mar 9;12(1):4154.PMID:35264693DOI:10.1038/s41598-022-07937-3.
Nonalcoholic fatty liver disease (NAFLD) is usually correlated with metabolic diseases, such as obesity, insulin resistance, and hyperglycemia. Herein, we investigated the inhibitory effects and underlying governing mechanism of Clitorin in a western diet (WD)-induced hepatic steatosis mouse model, and in oleic acid-stimulated HepG2 cells. Male C57BL/6 mice were fed a normal diet, WD, WD + 10 or 20 mg/kg orlistat, and WD + 10 or 20 mg/kg Clitorin. HepG2 cells were treated with 1 mM oleic acid to induce lipid accumulation with or without Clitorin. Clitorin significantly alleviated body weight gain and hepatic steatosis features (NAFLD activity score, micro-, and macro-vesicular steatosis) in WD-induced hepatic steatosis mice. Additionally, Clitorin significantly decreased protein expressions of sterol regulatory element-binding protein 1 (SREBP1), peroxisome proliferator-activated receptor γ (PPARγ), and CCAAT/enhancer binding protein α (C/EBPα) in WD-induced hepatic steatosis mice. Moreover, Clitorin significantly diminished the mRNA levels of SREBP1, acetyl-CoA carboxylase (ACC), fatty acid synthase (FAS), and hydroxy-3-methylglutaryl coenzyme A reductase (HMGCR) and enhanced the mRNA levels of peroxisome proliferator-activated receptor α (PPARα) and carnitine palmitoyltranserase-1 (CTP-1), as well as adenosine monophosphate-activated protein kinase (AMPK) in the liver of WD-induced hepatic steatosis mice and oleic acid-stimulated HepG2 cells. Overall, our findings demonstrated that Clitorin can be a potentially efficacious candidate for NAFLD management.

Chemical constituents from Carica papaya Linn. leaves as potential cytotoxic, EGFRwt and aromatase (CYP19A) inhibitors; a study supported by molecular docking
RSC Adv 2022 Mar 23;12(15):9154-9162.PMID:35424860DOI:10.1039/d1ra07000b.
The phytochemical investigation of the hydromethanolic extract of Carica papaya Linn. leaves (Caricaceae) resulted in the isolation and characterization of ten compounds, namely; carpaine (1), methyl gallate (2), loliolide (3), rutin (4), Clitorin (5), kaempferol-3-O-neohesperidoside (6), isoquercetin (7), nicotiflorin (8) and isorhamnetin-3-O-β-d-glucopyranoside (9). The compounds 2, 3, 5-7 and 9 were isolated for the first time from the genus Carica. An in vitro breast cancer cytotoxicity study was evaluated with an MCF-7 cell line using the MTT assay. Methyl gallate and Clitorin demonstrated the most potent cytotoxic activities with an IC50 of 1.11 ± 0.06 and 2.47 ± 0.14 μM, respectively. Moreover, methyl gallate and nicotiflorin exhibited potential EGFRwt kinase inhibition activities with an IC50 of 37.3 ± 1.9 and 41.08 ± 2.1 nM, respectively, compared with the positive control erlotinib (IC50 = 35.94 ± 1.8 nM). On the other hand, Clitorin and nicotiflorin displayed the strongest aromatase kinase inhibition activities with an IC50 of 77.41 ± 4.53 and 92.84 ± 5.44 nM, respectively. Clitorin was comparable to the efficacy of the standard drug letrozole (IC50 = 77.72 ± 4.55). Additionally, molecular docking simulations of the isolated compounds to EGFR and human placental aromatase cytochrome P450 (CYP19A1) were evaluated. Methyl gallate linked with the EGFR receptor through hydrogen bonding with a pose score of -4.5287 kcal mol-1 and RMSD value of 1.69 Å. Clitorin showed the strongest interaction with aromatase (CYP19A1) for the breast cancer receptor with a posing score of -14.2074 and RMSD value of 1.56 Å. Compounds (1-3) possessed a good bioavailability score with a 0.55 value.
HPLC-based activity profiling for antiplasmodial compounds in the traditional Indonesian medicinal plant Carica papaya L
J Ethnopharmacol 2014 Aug 8;155(1):426-34.PMID:24892830DOI:10.1016/j.jep.2014.05.050.
Ethnopharmacological relevance: Leaf decoctions of Carica papaya have been traditionally used in some parts of Indonesia to treat and prevent malaria. Leaf extracts and fraction have been previously shown to possess antiplasmodial activity in vitro and in vivo. Materials and methods: Antiplasmodial activity of extracts was confirmed and the active fractions in the extract were identified by HPLC-based activity profiling, a gradient HPLC fractionation of a single injection of the extract, followed by offline bioassay of the obtained microfractions. For preparative isolation of compounds, an alkaloidal fraction was obtained via adsorption on cationic ion exchange resin. Active compounds were purified by HPLC-MS and MPLC-ELSD. Structures were established by HR-ESI-MS and NMR spectroscopy. For compounds 5 and 7 absolute configuration was confirmed by comparison of experimental and calculated electronic circular dichroism (ECD) spectroscopy data, and by X-ray crystallography. Compounds were tested for bioactivity in vitro against four parasites (Trypanosoma brucei rhodesiense, Trypanosoma cruzi, Leishmania donovani, and Plasmodium falciparum), and in the Plasmodium berghei mouse model. Results: Profiling indicated flavonoids and alkaloids in the active time windows. A total of nine compounds were isolated. Four were known flavonols--manghaslin, Clitorin, rutin, and nicotiflorin. Five compounds isolated from the alkaloidal fraction were piperidine alkaloids. Compounds 5 and 6 were inactive carpamic acid and methyl carpamate, while three alkaloids 7-9 showed high antiplasmodial activity and low cytotoxicity. When tested in the Plasmodium berghei mouse model, carpaine (7) did not increase the survival time of animals. Conclusions: The antiplasmodial activity of papaya leaves could be linked to alkaloids. Among these, carpaine was highly active and selective in vitro. The high in vitro activity could not be substantiated with the in vivo murine model. Further investigations are needed to clarify the divergence between our negative in vivo results for carpaine, and previous reports of in vivo activity with papaya leaf extracts.
Antihypertensive effect of Carica papaya via a reduction in ACE activity and improved baroreflex
Planta Med 2014 Nov;80(17):1580-7.PMID:25295669DOI:10.1055/s-0034-1383122.
The aims of this study were to evaluate the antihypertensive effects of the standardised methanolic extract of Carica papaya, its angiotensin converting enzyme inhibitory effects in vivo, its effect on the baroreflex and serum angiotensin converting enzyme activity, and its chemical composition. The chemical composition of the methanolic extract of C. papaya was evaluated by liquid chromatography-mass/mass and mass/mass spectrometry. The angiotensin converting enzyme inhibitory effect was evaluated in vivo by Ang I administration. The antihypertensive assay was performed in spontaneously hypertensive rats and Wistar rats that were treated with enalapril (10 mg/kg), the methanolic extract of C. papaya (100 mg/kg; twice a day), or vehicle for 30 days. The baroreflex was evaluated through the use of sodium nitroprusside and phenylephrine. Angiotensin converting enzyme activity was measured by ELISA, and cardiac hypertrophy was evaluated by morphometric analysis. The methanolic extract of C. papaya was standardised in ferulic acid (203.41 ± 0.02 µg/g), caffeic acid (172.60 ± 0.02 µg/g), gallic acid (145.70 ± 0.02 µg/g), and quercetin (47.11 ± 0.03 µg/g). The flavonoids quercetin, rutin, nicotiflorin, Clitorin, and manghaslin were identified in a fraction of the extract. The methanolic extract of C. papaya elicited angiotensin converting enzyme inhibitory activity. The antihypertensive effects elicited by the methanolic extract of C. papaya were similar to those of enalapril, and the baroreflex sensitivity was normalised in treated spontaneously hypertensive rats. Plasma angiotensin converting enzyme activity and cardiac hypertrophy were also reduced to levels comparable to the enalapril-treated group. These results may be associated with the chemical composition of the methanolic extract of C. papaya, and are the first step into the development of a new phytotherapic product which could be used in the treatment of hypertension.
