Abstract
Angiogenesis is a crucial process in the progression of various pathologies, like solid tumors, wet age-related macular degeneration, and chronic inflammation. Current anti-angiogenic treatments still have major drawbacks like limited efficacy in diseases that also rely on inflammation. Therefore, new anti-angiogenic approaches are sorely needed, and simultaneous inhibition of angiogenesis and inflammation is desirable. Here, we show that 2-desaza-annomontine (C81), a derivative of the plant alkaloid annomontine previously shown to inhibit endothelial inflammation, impedes angiogenesis by inhibiting CDC2-like kinases (CLKs) and WNT/β-catenin signaling. C81 reduced choroidal neovascularization in a laser-induced murine in vivo model, inhibited sprouting from vascular endothelial growth factor A (VEGF-A)-activated murine aortic rings ex vivo, and reduced angiogenesis-related activities of endothelial cells in multiple functional assays. This was largely phenocopied by CLK inhibitors and knockdowns, but not by inhibitors of the other known targets of C81. Mechanistically, CLK inhibition reduced VEGF receptor 2 (VEGFR2) mRNA and protein expression as well as downstream signaling. This was partly caused by a reduction of WNT/β-catenin pathway activity, as activating the pathway induced, while β-catenin knockdown impeded VEGFR2 expression. Surprisingly, alternative splicing of VEGFR2 was not detected. In summary, C81 and other CLK inhibitors could be promising compounds in the treatment of diseases that depend on angiogenesis and inflammation due to their impairment of both processes.

HPLC- and NMR-Based Chemical Profiling, Wound-Healing Potential, Anti-Inflammatory and Antibacterial Activities of Satureja pilosa (Lamiaceae), a Neglected Medicinal-Aromatic Herb. PLANTS (BASEL, SWITZERLAND) 2023; 12:4114.

Abstract
Satureja pilosa Velen. (Lamiaceae) is a perennial and melliferous aromatic-medicinal subshrub which is range-restricted in adjacent parts of Greece and Bulgaria and locally in Italy, known in Northern Greece as wild oregano ("agriorigani") and traditionally collected from the wild for culinary purposes. Since the ethnopharmacological data and modern biological activities of Satureja spp. suggest promising applications in skin conditions, the present study aimed to investigate the hitherto unknown phenolic content of cultivated S. pilosa and its potential biological activities, focusing mainly on wound-healing and anti-inflammatory effects. An HPLC-PDA-MS-targeted phytochemical investigation, along with NMR, allowed for the isolation and characterization of the main constituents, resulting in 18 compounds. Representative extracts and purified compounds were tested for wound-healing activity on NIH/3T3 fibroblasts. The butanol extract exhibited a significantly higher cell migration rate (73.4%) compared to aqueous (50.6%) and methanolic (49.6%) ones, enhancing the cell migration more rapidly at both concentration levels, whilst rosmarinic acid was the most potent among the isolated compounds, with a migration rate of 64.0% at the concentration level of 10-5 mg/mL, followed by 3,4-dihydrophenyllactic acid (54.7%). Moreover, potential effects on endothelial activation processes were explored, including the leukocyte-endothelial cell interaction during inflammatory processes and the migratory capacity during angiogenic actions, since these processes are commonly associated with skin diseases. Finally, extracts and purified compounds demonstrated weak antibacterial potential against two important pathogens (Staphylococcus aureus and Pseudomonas aeruginosa), suggesting that further investigation is warrented.

Front Pharmacol 2022; 13:844767. [PMID: 35281937 PMCID: PMC8914105 DOI: 10.3389/fphar.2022.844767] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2021] [Accepted: 01/31/2022] [Indexed: 12/15/2022] Open
Abstract
Rhizomes from Zingiber officinale Roscoe are traditionally used for the treatment of a plethora of pathophysiological conditions such as diarrhea, nausea, or rheumatoid arthritis. While 6-gingerol is the pungent principle in fresh ginger, in dried rhizomes, 6-gingerol is dehydrated to 6-shogaol. 6-Shogaol has been demonstrated to exhibit anticancer, antioxidative, and anti-inflammatory actions more effectively than 6-gingerol due to the presence of an electrophilic Michael acceptor moiety. In vitro, 6-shogaol exhibits anti-inflammatory actions in a variety of cell types, including leukocytes. Our study focused on the effects of 6-shogaol on activated endothelial cells. We found that 6-shogaol significantly reduced the adhesion of leukocytes onto lipopolysaccharide (LPS)-activated human umbilical vein endothelial cells (HUVECs), resulting in a significantly reduced transmigration of THP-1 cells through an endothelial cell monolayer. Analyzing the mediators of endothelial cell–leukocyte interactions, we found that 30 µM of 6-shogaol blocked the LPS-triggered mRNA and protein expression of cell adhesion molecules. In concert with this, our study demonstrates that the LPS-induced nuclear factor κB (NFκB) promoter activity was significantly reduced upon treatment with 6-shogaol. Interestingly, the nuclear translocation of p65 was slightly decreased, and protein levels of the LPS receptor Toll-like receptor 4 remained unimpaired. Analyzing the impact of 6-shogaol on angiogenesis-related cell functions in vitro, we found that 6-shogaol attenuated the proliferation as well as the directed and undirected migration of HUVECs. Of note, 6-shogaol also strongly reduced the chemotactic migration of endothelial cells in the direction of a serum gradient. Moreover, 30 µM of 6-shogaol blocked the formation of vascular endothelial growth factor (VEGF)-induced endothelial sprouts from HUVEC spheroids and from murine aortic rings. Importantly, this study shows for the first time that 6-shogaol exhibits a vascular-disruptive impact on angiogenic sprouts from murine aortae. Our study demonstrates that the main bioactive ingredient in dried ginger, 6-shogaol, exhibits beneficial characteristics as an inhibitor of inflammation- and angiogenesis-related processes in vascular endothelial cells.
