Unripe Carica papaya Protects Methylglyoxal-Invoked Endothelial Cell Inflammation and Apoptosis via the Suppression of Oxidative Stress and Akt/MAPK/NF-κB Signals. Antioxidants (Basel) 2021; 10:antiox10081158. [PMID: 34439407 PMCID: PMC8388906 DOI: 10.3390/antiox10081158] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2021] [Revised: 07/16/2021] [Accepted: 07/19/2021] [Indexed: 12/24/2022] Open
Abstract
Methylglyoxal (MGO), a highly reactive dicarbonyl compound, causes endothelial oxidative stress and vascular complications in diabetes. Excessive MGO-induced ROS production triggers eNOS uncoupling, inflammatory responses, and cell death signaling cascades. Our previous study reported that unripe Carica papaya (UCP) had antioxidant activities that prevented H2O2-induced endothelial cell death. Therefore, this study investigated the preventive effect of UCP on MGO-induced endothelial cell damage, inflammation, and apoptosis. The human endothelial cell line (EA.hy926) was pretreated with UCP for 24 h, followed by MGO-induced dicarbonyl stress. Treated cells were evaluated for intracellular ROS/O2•− formation, cell viability, apoptosis, NO releases, and cell signaling through eNOS, iNOS, COX-2, NF-κB, Akt, MAPK (JNK and p38), and AMPK/SIRT1 autophagy pathways. UCP reduced oxidative stress and diminished phosphorylation of Akt, stress-activated MAPK, leading to the decreases in NF-kB-activated iNOS and COX-2 expression. However, UCP had no impact on the autophagy pathway (AMPK and SIRT1). Although UCP pretreatment decreased eNOS phosphorylation, the amount of NO production was not altered. The signaling of eNOS and NO production were decreased after MGO incubation, but these effects were unaffected by UCP pretreatment. In summary, UCP protected endothelial cells against carbonyl stress by the mechanisms related to ROS/O2•− scavenging activities, suppression of inflammatory signaling, and inhibition of JNK/p38/apoptosis pathway. Thus, UCP shows considerable promise for developing novel functional food and nutraceutical products to reduce risks of endothelial inflammation and vascular complications in diabetes.

Abstract
Azoles are a family of five-membered azacyclic compounds with relevant biological and pharmacological activity. Different subclasses of azoles are defined depending on the atomic arrangement and the number of nitrogen atoms present in the ring: pyrazoles, indazoles, imidazoles, benzimidazoles, triazoles, benzotriazoles, tetrazoles and pentazoles. The complete characterization of their structure and the knowledge about their crystal packing and physical and chemical properties are of vital importance for the advancement in the design of new azole-containing drugs. In this review, we report the latest recent contributions to azole chemistry, in particular, those in which theoretical studies have been performed.

Abstract
Curcumin is an admired, plant-derived compound that has been extensively investigated for diverse range of biological activities, but the use of this polyphenol is limited due to its instability. Chemical modifications in curcumin are reported to seize this limitation; such efforts are intensively performed to discover molecules with similar but improved stability and better properties. Focal points of these reviews are synthesis of stable pyrazole and isoxazole analogs of curcumin and application in various biological systems. This review aims to emphasize the latest evidence of curcumin pyrazole analogs as a privileged scaffold in medicinal chemistry. Manifold features of curcumin pyrazole analogs will be summarized herein, including the synthesis of novel curcumin pyrazole analogs and the evaluation of their biological properties. This review is expected to be a complete, trustworthy and critical review of the curcumin pyrazole analogs template to the medicinal chemistry community.

Abstract
BACKGROUND A set of 2,5-diaryl-1,2,4-triazol-3-ones was synthesized in two steps and evaluated as regards their activity in some relevant biological targets related to cancer. OBJECTIVE This study is focused on the synthesis and the biological evaluation of 2,5-diaryl-1,2,4- triazol-3-ones. In this sense, the effect of the synthetic triazolones on the proliferation of HT-29 and A549 cancer cells and on HEK non-cancer cells has been measured. In addition, the effects of triazolones on the expression of hTERT, c-Myc and PD-L1 genes and on the production of c-Myc and PD-L1 proteins have also been evaluated. METHOD A set of 2,5-diaryl-1,2,4-triazol-3-ones was synthesized in two steps. Firstly, N- (aminocarbonyl)-3-methoxybenzamide was prepared by coupling 3-methoxybenzoic acid and cyanamide followed by aqueous HCl hydrolysis. Then, the 2,5-diaryl-1,2,4-triazol-3-ones were obtained upon reaction of N-(aminocarbonyl)-3-methoxybenzamide with arylhydrazines in decaline at 170ºC. The ability of the triazolones to inhibit cell proliferation was measured against two human carcinoma cell lines (colorectal HT-29 and lung A549), and one non-tumor cell line (HEK- 293) by MTT assay. The downregulation of the synthetic triazolones on the expression of the hTERT, c-Myc and PD-L1 genes was measured by an RT-qPCR analysis. Their ability to regulate the expression of the c-Myc and PD-L1 proteins, as well as their direct interaction with c-Myc protein, was determined by the ELISA method. Finally, the direct interaction of triazolones with PD-L1 protein was assessed by the thermal shift assay. RESULTS Ten 2,5-diaryl-1,2,4-triazol-3-ones were synthesized and characterized by spectroscopic methods. A thorough study by 1H, 13C, 15N and 19F NMR spectroscopy showed that all the synthetic compounds exist as 4H-triazolones and not as hydroxytriazoles or 1H-triazolones. Some triazolones showed relatively high activities together with very poor toxicity in non-tumor cell line HEK-293. 2-(2-fluorophenyl)-5-(3-methoxyphenyl)-2,4-dihydro-3H-1,2,4-triazol-3-one (4) was particularly active in downregulating c-Myc and PD-L1 gene expression although 2-(4- chloro-2-fluorophenyl)-5-(3-methoxyphenyl)-2,4-dihydro-3H-1,2,4-triazol-3-one (8) is the one that combines the best downregulatory activities in the three genes studied. Considering protein expression, the most active compounds are 2-(4-fluorophenyl)-5-(3-methoxyphenyl)-2,4-dihydro- 3H-1,2,4-triazol-3-one (5) and 2-(2,4,6-trifluorophenyl)-5-(3-methoxyphenyl)-2,4-dihydro-3H- 1,2,4-triazol-3-one (10) (c-Myc expression) and 2-(2,3,5,6-tetrafluorophenyl)-5-(3-methoxyphenyl)- 2,4-dihydro-3H-1,2,4-triazol-3-one (11) and (8) (PD-L1 expression). CONCLUSION Some of the triazolones studied have shown relevant activities in the inhibition of the hTERT, c-Myc and PD-L1 genes, and in the inhibition of c-Myc and PD-L1 protein secretion, the 2-(4-chloro-2-fluorophenyl)-5-(3-methoxyphenyl)-2,4-dihydro-3H-1,2,4-triazol-3-one (8) was found to be a particularly promising lead compound.

Abstract
Gardenia jasminoides is a plant that has been used in traditional Chinese medicine. It has four key active components (genipin gentiobioside, geniposide, crocin 1 and crocin 2). The aim of the present study was to determine the anti‑hypertension effects of Gardenia jasminoidesin vivo. The chemical composition of Gardenia jasminoides was determined using liquid chromatography. The anti‑hypertensive effects of Gardenia jasminoides were determined by a L‑NG‑nitroarginine (L‑NNA)‑induced hypertension animal model. Both Gardenia jasminoides plants of the Jiangjin County variety (CJGJ) and the Lichuan City variety (HLGJ) were used. HLGJ contained more geniposide than CJGJ. L‑NNA was used to induce hypertension in mice, and the mice were subsequently treated with CJGJ and HLGJ. The Gardenia jasminoides‑treated mice exhibited lower systolic (SBP), diastolic (DBP) and mean blood pressure (MBP) than the experimental control mice. Additionally, HLGL has a more potent effect on SBP, MBP and DBP than CJGJ. Following Gardenia jasminoides treatment, the nitric oxide contents in serum, heart, liver, kidney and stomach of mice were higher than the L‑NNA‑induced control mice, and the malondialdehyde contents were lower; the levels in HLGJ‑treated mice were closer to those normal mice than the levels in CJGJ‑treated mice were. Serum levels of endothelin‑1 and vascular endothelial growth factor were reduced by HLGJ treatment in hypertensive mice, whereas the calcitonin gene‑related peptide level was raised. Reverse transcription‑polymerase chain reaction analysis of mouse heart and vessel tissue demonstrated that HLGJ‑treated mice exhibited higher heme oxygenase‑1, neuronal nitric oxide synthase (nNOS), endothelial NOS, Bax, caspase‑3, caspase‑8, caspase‑9 mRNA expression levels and lower adrenomedullin, receptor activity modifying protein, interleukin‑1β, tumor necrosis factor‑α, inducible NOS, Bcl‑2, monocyte chemoattractant protein‑1, nuclear factor‑κB and matrix metalloproteinase‑2 and ‑9 mRNA expression compared with control hypertensive mice and CJGJ‑treated mice. In conclusion, Gardenia jasminoides has anti‑hypertensive effects, and these effects may be associated with the active component, geniposide.
