Flavones Inhibit the Activity of AKR1B10, a Promising Therapeutic Target for Cancer Treatment

AKR1B10 is an NADPH-dependent reductase that plays an important function in several physiological reactions such as the conversion of retinal to retinol, reduction of isoprenyl aldehydes, and biotransformation of procarcinogens and drugs. A growing body of evidence points to the important role of the enzyme in the development of several types of cancer (e.g., breast, hepatocellular), in which it is highly overexpressed. AKR1B10 is regarded as a therapeutic target for the treatment of these diseases, and potent and specific inhibitors may be promising therapeutic agents. Several inhibitors of AKR1B10 have been described, but the area of natural plant products has been investigated sparingly. In the present study almost 40 diverse phenolic compounds and alkaloids were examined for their ability to inhibit the recombinant AKR1B10 enzyme. The most potent inhibitors-apigenin, luteolin, and 7-hydroxyflavone-were further characterized in terms of IC50, selectivity, and mode of action. Molecular docking studies were also conducted, which identified putative binding residues important for the interaction. In addition, cellular studies demonstrated a significant inhibition of the AKR1B10-mediated reduction of daunorubicin in intact cells by these inhibitors without a considerable cytotoxic effect. Although these compounds are moderately potent and selective inhibitors of AKR1B10, they constitute a new structural type of AKR1B10 inhibitor and may serve as a template for the development of better inhibitors.

One new alkaloid from Chelidonium majus L

One new alkaloid, together with 10 known compounds were isolated from the aerial parts of Chelidonium majus L. by repeated silica gel column chromatography. Their chemical structures were elucidated on the basis of physicochemical and spectroscopic data. Among them, 6-acetonyldihydrochelerythrine (4), 6-acetonyldihydrosanguinarine (5), 6-ketenesanguinarine (6), demethylchelerythrine (7) and demethylsanguinarine (11) were isolated for the first time from this plant. Compound 6 was identified as a new compound. These compounds were screened for cytotoxicity against human non-small lung carcinoma (H1299), breast cancer (MCF-7) and liver cancer (SMMC-7721). In a series of cytotoxic tests, compounds 9 and 10 displayed potent cytotoxic activity against H1299, MCF-7 and SMMC-7721, with the IC50values of 8.16-35.25 mug/mL.

New anti-Alzheimer drugs from biodiversity: The role of the natural acetylcholinesterase inhibitors

Alzheimer’s disease (AD) is a progressive neurodegenerative pathology with severe economic and social impact. There is currently no cure, although cholinesterase inhibitors provide effective temporary relief of symptoms in some patients. Nowadays, drug research and development are based on the cholinergic hypothesis that supports the cognition improvement by regulation of the synthesis and release of acetylcholine in the brain. There are only four commercial medicines approved for treatment of AD, and natural products have played an important alternative role in the research for new acetylcholinesterase inhibitors, as exemplified through the discovery of galantamine. This profile conducts us to give in this paper an overview relating the several classes of natural products with anti-cholinesterasic activity as potential templates to the design of new selective and powerful anti-Alzheimer drugs.

Identifying cancer-related molecular targets of Nandina domestica Thunb. by network pharmacology-based analysis in combination with chemical profiling and molecular docking studies

Ethnopharmacological relevance: The fruits of Nandina domestica Thunb. have served as folk medicines in Chinese and Japanese tradition for treatment of several tumors including pharynx tumor and tooth abscess for many years, yet its exact mechanism of action is not yet known. Aim of the study: The study targets the identification of the main constituents of the fruits extracts and investigation of their mode of action in cancer therapy via pharmacology-based analysis and molecular docking. Materials and methods: The different extracts of N. domestica Thunb. were analyzed via UPLC?MS/MS for identification of their active constituents. STITCH, DAVID, KEGG and STRING database were utilized for construction of compound-target and compound-target-pathway networks using Cytoscape 3.2.1. Molecular docking analysis of the top hit compounds was performed against the identified top hit molecular targets in the constructed networks. In vitro-testing of Nandina domestica Thunb. against colorectal cancer cell lines was carried out and correlated to the chemical profile of the extract to identify important biomarkers. The ADME properties of the active compounds were also evaluated. Results: 22 compounds were identified by UPLC?MS/MS analysis and were forwarded to network pharmacology-based analysis. Results showed the enrichment of 5 compounds and 4 molecular targets in the network namely; AKT1, CASP3, MAPK1 and TP53. The pathway analysis of the identified targets revealed that 15 cancer-related pathways were enriched including colorectal cancer, endometrial cancer and small-cell lung cancer. In-vitro testing of the extracts against colo-rectal cancer cell lines revealed the fractions enriched in the identified hit compounds were indeed the most active as revealed from the HCA-heat-map. ADME results showed that all compounds were drug-like candidates showing acceptable values according to Lipinski’s rule. Conclusions: Network pharmacology analysis revealed that the compounds isoquercitrin, quercitrin, berberine, chlorogenic acid and caffeic acid showed strong synergistic interactions with the cancer-related targets and pathways. It could be concluded that N. domestica Thunb. constituents affect both apoptosis and Akt-signaling pathways during the stages of early and intermediate adenoma through interaction with the targets CASP3 and MAPK1 (ErC2) while during the stages of late adenoma and carcinoma, the compounds acts through the p53 and ErbB signaling pathways.

Characterization of isoquinolin alkaloids from Fumaria agraria and evaluation of their antiproliferative activity against human breast cancer cell lines

Fumaria agraria (Fumariaceae) is an annual plant used traditionally in Algeria for various medicinal purposes. Alkaloids extracts from areal parts were subjected to solvent fractionation and GCMS analysis. Rates of alkaloids recorded were respectively of 700 mg/100 g of Dry Weight of total alkaloids ?TA?, 400 mg/100 g DWof neutral fraction ?NF?, 40 mg/100 g DW of acid fraction ?AF? and 250 mg/100 g DWof the basic fraction ?BF?. Protopine was found to be the most potent alkaloid of the total extract (41.55%). Fractionation showed that Protopine was found essentially in the BF fraction (60.7%). Antiproliferative activities of total alkaloids extract and BF fraction were assessed on MCF-7 and MDAMB- 231 breast cancer and MCF10A mammary normal cell lines, by trypan blue exclusion essay. Both TA extract and BF fraction showed potent antiproliferative activities against MCF-7 breast cancer cells in varying degrees with respective IC50 of 47.8 ¡À 1.8 mug/ml and 17.6 ¡À 0.4 muM, without cell death induction but no impact was observed on normal MCF-10A cell growth. MCF7 Cell line was most sensitive (IC50 of 17,6 ¡À 0,4muM) to BF fraction effect than MDAMB-231 one (IC50 of 36,4 ¡À 0,6muM). Isoquinolein alkaloids of Fumaria agraria and specially the fraction which contain Protopine showed potent antiproliferative activity against breast cancer cells.
