Abstract
The discoveries recommend that the photoinduced conditions of fluorescein-determined go about as impetus for photochemically combining polysubstituted quinolines in ethanol at room temperature under air environment by means of revolutionary Friedländer hetero-annulation of 2-aminoaryl ketone and α-methylene carbonyl compound. This study lays out an original capability for photochemically orchestrating fluorescein. This non-metallic organic dye is economically accessible and modest, producing great outcomes, accelerating the cycle, and achieving a high compound economy. The turnover number (TON) and turnover recurrence (TOF) of polysubstituted quinolines have been determined. This cycle will likewise run on a gram scale, demonstrating the chance of modern applications.

Mohamadpour F. The development of Friedländer heteroannulation through a single electron transfer and energy transfer pathway using methylene blue (MB +). Sci Rep 2022; 12:7253. [PMID: 35508509 PMCID: PMC9068815 DOI: 10.1038/s41598-022-11349-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2022] [Accepted: 04/22/2022] [Indexed: 11/08/2022] Open
Abstract
The radical Friedländer hetero-annulation of 2-aminoaryl ketone and -methylene carbonyl compound was used to develop a green tandem approach for the metal-free synthesis of polysubstitutedquinolines. At room temperature in an ethanol solvent, photo-excited state functions generated from MB+ were used as single-electron transfer (SET) and energy transfer (EnT) catalysts, utilizing visible light as a renewable energy source in the air atmosphere. The purpose of this research is to increase the use of a nonmetal cationic dye that is both inexpensive and widely available. High yields, energy-effectiveness, high atom economy, time-saving features of the reaction, and operational simplicity, and the least amount of a catalyst are the benefits of this study. As a result, a wide range of ecological and long-term chemical properties are obtained. Polysubstitutedquinolines' turnover number (TON) and turnover frequency (TOF) have been calculated. Surprisingly, such cyclization can be accomplished on a gram scale, indicating that the process has industrial potential.

Novel hydroxybenzylamine-deoxyvasicinone hybrids as anticholinesterase therapeutics for Alzheimer's disease. Bioorg Med Chem 2021; 45:116311. [PMID: 34304133 DOI: 10.1016/j.bmc.2021.116311] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2021] [Revised: 07/09/2021] [Accepted: 07/10/2021] [Indexed: 12/31/2022]
Abstract
A series of novel 2-hydroxybenzylamine-deoxyvasicinone hybrid analogs (8a-8n) have been synthesized and evaluated as inhibitors of acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE), and as inhibitors of amyloid peptide (Aβ1-42) aggregation, for treatment of Alzheimer's disease (AD). These dual acting compounds exhibited good AChE inhibitory activities ranging from 0.34 to 6.35 µM. Analogs8g and 8n were found to be the most potent AChE inhibitors in the series with IC50values of 0.38 µM and 0.34 µM, respectively. All the analogs (8a-8n) exhibited weak BuChE inhibitory activities ranging from 14.60 to 21.65 µM. Analogs8g and 8n exhibited BuChE with IC50values of 15.38 µM and 14.60 µM, respectively, demonstrating that these analogs were greater than 40-fold more selective for inhibition of AChE over BuChE. Additionally, compounds8g and 8n were also found to be the best inhibitors of self-induced Aβ1-42 peptide aggregation with IC50values of 3.91 µM and 3.22 µM, respectively; 8g and 8n also inhibited AChE-induced Aβ1-42 peptide aggregation by 68.7% and 72.6%, respectively. Kinetic analysis and molecular docking studies indicate that analogs 8g and 8n bind to a new allosteric pocket (site B) on AChE. In addition, the observed inhibition of AChE-induced Aβ1-42 peptide aggregation by 8n is likely due to allosteric inhibition of the binding of this peptide at the CAS site on AChE. Overall, these results indicate that 8g and 8n are examples of dual-acting lead compounds for the development of highly effective anti-AD drugs.

Peganum spp.: A Comprehensive Review on Bioactivities and Health-Enhancing Effects and Their Potential for the Formulation of Functional Foods and Pharmaceutical Drugs. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2021; 2021:5900422. [PMID: 34257813 PMCID: PMC8260309 DOI: 10.1155/2021/5900422] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/06/2021] [Revised: 06/06/2021] [Accepted: 06/09/2021] [Indexed: 11/18/2022]
Abstract
The genus Peganum includes four species widely distributed in warm temperate to subtropical regions from the Mediterranean to Mongolia as well as certain regions in America. Among these species, Peganum harmala L., distributed from the Mediterranean region to Central Asia, has been studied and its phytochemical profile, traditional folk use, and application in pharmacological and clinical trials are well known. The review is aimed at presenting an insight into the botanical features and geographical distribution of Peganum spp. along with traditional folk uses. This manuscript also reviews the phytochemical profile of Peganum spp. and its correlation with biological activities evidenced by the in vitro and in vivo investigations. Moreover, this review gives us an understanding of the bioactive compounds from Peganum as health promoters followed by the safety and adverse effects on human health. In relation to their multipurpose therapeutic properties, various parts of this plant such as seeds, bark, and roots present bioactive compounds promoting health benefits. An updated search (until December 2020) was carried out in databases such as PubMed and ScienceDirect. Chemical studies have presented beta-carboline alkaloids as the most active constituents, with harmalol, harmaline, and harmine being the latest and most studied among these naturally occurring alkaloids. The Peganum spp. extracts have shown neuroprotective, anticancer, antimicrobial, and antiviral effects. The extracts are also found effective in improving respiratory disorders (asthma and cough conditions), dermatoses, and knee osteoarthritis. Bioactivities and health-enhancing effects of Peganum spp. make it a potential candidate for the formulation of functional foods and pharmaceutical drugs. Nevertheless, adverse effects of this plant have also been described, and therefore new bioproducts need to be studied in depth. In fact, the design of new formulations and nanoformulations to control the release of active compounds will be necessary to achieve successful pharmacological and therapeutic treatments.

Abstract
Phytophenols are important bioactive food based chemical entities, largely present in several natural sources. Among them, sesamol is one of the key natural phenols found in sesame seeds, Piper cubeba etc. Several studies have reported that sesame oil is a potent cardioprotective functional food. Papers on the utility of sesamol in sesame oil (the chemical name of sesamol is methylenedioxyphenol, MDP) have appeared in the literature, though there is no single concise review on the usefulness of sesamol in sesame oil in CVD in the literature. Cardiovascular disease (CVD) is the most challenging health problem encountered by the global population. There has been increasing interest in the growth of effective cardiovascular therapeutics, specifically of natural origin. Among various natural sources of chemicals, phytochemicals are micronutrients and bio-compatible scaffolds having an extraordinary efficacy at multiple disease targets with minimal or no adverse effect. This review offers a perspective on the existing literature on functional ingredients in sesame oil with particular focus on sesamol and its derivatives having nutritional and cardioprotective properties. This is demonstrated to have shown a specifically modulating oxidative enzyme myeloperoxidase (MPO) and other proteins which are detrimental to human well-being. The molecular mechanism of cardioprotection by this food ingredient is primarily attributed to the methylenedioxy group present in the sesamol component.

Abstract
Cell cycle dysregulation is the mainstay of aberrant cell proliferation, which leads to tumor progression. Mutations in tumor cells initiate various dysregulated pathways and spontaneous over-proliferation with genomic/chromosomal instability. Despite advances in cancer therapy, it has remained a medicinal challenge to treat. Besides, the complexity of pathophysiological pathways behind cancer raises the need for novel multi-target agents, possessing fewer side effects. Alkaloid-based therapies have been explored so far to target cell division in cancer, including vinca alkaloids. As a class of hopeful β-carboline derivatives, growing evidence has indicated their auspicious roles in combating cancer by inhibiting topoisomerase (TOPO), kinesin Eg5, telomerase, cyclin-dependent kinase (CDK), IκB kinase (IKK), and polo-like kinase-1 (PLK1) in the transition phases of cell cycle. In this review, in vitro potential of β-carboline has been revealed through targeting cell division cycle at different phases. In conclusion, β-carboline alkaloids could be introduced as novel candidates in cancer therapy.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The plants of the genus Peganum have a long history as a Chinese traditional medicine for the treatment of cough, hypertension, diabetes, asthma, jaundice, colic, lumbago, and many other human ailments. Additionally, the plants can be used as an amulet against evil-eye, dye and so on, which have become increasingly popular in Asia, Iran, Northwest India, and North Africa. AIM OF THE REVIEW The present paper reviewed the ethnopharmacology, phytochemistry, analytical methods, biological activities, metabolism, pharmacokinetics, toxicology, and drug interaction of the genus Peganum in order to assess the ethnopharmacological use and to explore therapeutic potentials and future opportunities for research. MATERIALS AND METHODS Information on studies of the genus Peganum was gathered via the Internet (using Google Scholar, Baidu Scholar, Elsevier, ACS, Pudmed, Web of Science, CNKI and EMBASE) and libraries. Additionally, information was also obtained from some local books, PhD and MS's dissertations. RESULTS The genus Peganum has played an important role in traditional Chinese medicine. The main bioactive metabolites of the genus include alkaloids, flavonoids, volatile oils, etc. Scientific studies on extracts and formulations revealed a wide range of pharmacological activities, such as cholinesterase and monoamine oxidase inhibitory activities, antitumor, anti-hypertension, anticoagulant, antidiabetic, antimicrobial, insecticidal, antiparasidal, anti-leishmaniasis, antioxidant, and anti-inflammatory. CONCLUSIONS Based on this review, there is some evidence for extracts' pharmacological effects on Alzheimer's and Parkinson's diseases, cancer, diabetes, hypertension. Some indications from ethnomedicine have been confirmed by pharmacological effects, such as the cholinesterase, monoamine oxidase and DNA topoisomerase inhibitory activities, hypoglycemic and vasodilation effects of this genus. The available literature showed that most of the activities of the genus Peganum can be attributed to the active alkaloids. Data regarding many aspects of the genus such as mechanisms of actions, metabolism, pharmacokinetics, toxicology, potential drug interactions with standard-of-care medications is still limited which call for additional studies particularly in humans. Further assessments and clinical trials should be performed before it can be integrated into medicinal practices.

Investigation of the alkaloids from Peganum harmala seeds yielded two pairs of unique racemic pyrroloindole alkaloids, (±)-peganines A-B (1-2); two rare thiazole derivatives, peganumals A-B (3-4); six new β-carboline alkaloids, pegaharmines F-K (5-10); and 12 known analogues. Their structures, including stereochemistry, were elucidated through spectroscopic analyses, quantum chemistry calculations, and single-crystal X-ray diffraction. Notably, the incorporation of pyrrole and indole moieties in peganines A-B, thiazole fragments in peganumals A-B, and a C-1 α,β-unsaturated ester motif in pegaharmine F (5) are all rare, and their presence in the genus Peganum were demonstrated for the first time. All isolates were tested for antiproliferative activities against the HL-60, PC-3, and SGC-7901 cancer cell lines, and compounds 9, 11, 12, and 13 exhibited moderate cytotoxicity against HL-60 cancer cell lines with IC50 values in the range of 4.36-9.25 μM.

Abstract
Bioactivity-guided fractionation was used to determine the cytotoxic alkaloids from the toxic plant Peganum harmala. Two novel indole alkaloids, together with ten known ones, were isolated and identified. The novel alkaloids were elucidated to be 2-(indol-3-yl)ethyl-α-L-rhamnopyranosyl-(1 → 6)-β-D-glucopyranoside (2) and 3-hydroxy-3-(N-acetyl-2-aminoethyl)-6-methoxyindol-2-one (3). The cytotoxicity against human leukemia cells was assayed for the alkaloids and some of them showed potent activity. Harmalacidine (compound 8, HMC) exhibited the highest cytotoxicity against U-937 cells with IC50 value of 3.1 ± 0.2 μmol/L. The cytotoxic mechanism of HMC was targeting the mitochondrial and protein tyrosine kinase signaling pathways (PTKs-Ras/Raf/ERK). The results strongly demonstrated that the alkaloids from Peganum harmala could be a promising candidate for the therapy of leukemia.

Abstract
Canthinones are natural substances with a wide range of biological activities, including antipyretic, antiparasitic, and antimicrobial. Antiproliferative and/or cytotoxic effects of canthinones on cancer cells have also been described, although their mechanism of action remains ill defined. To gain better insight into this mechanism, the antiproliferative effect of a commercially available canthin-6-one (1) was examined dose-dependently on six cancer cell lines (human prostate, PC-3; human colon, HT-29; human lymphocyte, Jurkat; human cervix, HeLa; rat glioma, C6; and mouse embryonic fibroblasts, NIH-3T3). Cytotoxic effects of 1 were investigated on the same cancer cell lines by procaspase-3 cleavage and on normal human skin fibroblasts. Strong antiproliferative effects of the compound were observed in all cell lines, whereas cytotoxic effects were very dependent on cell type. A better definition of the mechanism of action of 1 was obtained on PC-3 cells, by showing that it decreases BrdU incorporation into DNA by 60% to 80% and mitotic spindle formation by 70% and that it causes a 2-fold accumulation of cells in the G2/M phase of the cell cycle. Together, the data suggest that the primary effect of canthin-6-one (1) is antiproliferative, possibly by interfering with the G2/M transition. Proapoptotic effects might result from this disturbance of the cell cycle.

Abstract
Screening for suppressors of canthin-6-one toxicity in yeast identified Yap1, a transcription factor involved in cell response to a broad range of injuries. Although canthin-6-one did not promote a significant oxidative stress, overexpression of YAP1 gene clearly increased resistance to this drug. We demonstrated that Yap1-mediated resistance involves the plasma membrane major-facilitator-superfamily efflux pump Flr1 but not the vacuolar ATP-binding-cassette transporter Ycf1. FLR1 overexpression was sufficient to reduce sensitivity to the drug, but strictly dependent on a functional YAP1 gene.

Abstract
Non-specific lipid transfer proteins (ns-LTPs), ubiquitously found in various types of plants, have been well-known to transfer amphiphilic lipids and promote the lipid exchange between mitochondria and microbody. In this study, an in silico analysis was proposed to study ns-LTP in Peganum harmala L., which may belong to ns-LTP1 family, aiming at constructing its three-dimensional structure. Moreover, we adopted MEGA to analyze ns-LTPs and other species phylogenetically, which brought out an initial sequence alignment of ns-LTPs. In addition, we used molecular docking and molecular dynamics simulations to further investigate the affinities and stabilities of ns-LTP with several ligands complexes. Taken together, our results about ns-LTPs and their ligand-binding activities can provide a better understanding of the lipid-protein interactions, indicating some future applications of ns-LTP-mediated transport.

Abstract
Luotonins are alkaloids from the aerial parts of Peganum nigellastrum Bunge. that display three major skeleton types. Luotonins A, B, and E are pyrroloquinazolino-quinoline alkaloids, luotonins C and D are canthin-6-one alkaloids, and luotonin F is a 4(3H)-quinazolinone alkaloid. All six luotonins have shown promising cytotoxicities towards selected human cancer cell lines, especially against leukemia P-388 cells. Luotonin A is the most active one, with its activity stemming from topoisomerase I-dependent DNA-cleavage. Such intriguing biological activities and unique structures have led not only to the development of synthetic methods for the efficient synthesis of these compounds, but also to interest in structural modifications for improving the biological properties. Recent progress in the study of luotonins is covered.

Abstract
Four lupane-type triterpenoids (1–4) and seven alkaloids (5–11) were isolated from the roots of Peganum nigellastrum. On the basis of spectroscopic and chemical evidence, the structures of the compounds were elucidated as 3α-hydroxy-27- trans-caffeoyloxylup-20(29)-en-28-oic acid methyl ester (1), 3β-hydroxy-27- trans-caffeoyloxylup-20(29)-en-28-oic acid methyl ester (2), 3α-acetoxy-27- trans-caffeoyloxylup-20(29)-en-28-oic acid methyl ester (3), 3β-acetoxy-27- trans-caffeoyloxylup-20(29)-en-28-oic acid methyl ester (4), luotonin C (5), luotonin D (6), harmine (7), harmol (8), harmaline (9), deoxyvasicinone (10) and vasicinone (11). Compounds 1, 3 and 4 are novel triterpenoids, and these pentacyclic triterpenoids were evaluated for their cytotoxicity against the androgen-sensitive LNCaP and androgen-independent PC-3 human prostate cancer cells.

Abstract
The Rutaceae continues to be the primary source of new alkyl-, aryl-, and alkylarylquinolin/ones. In the past 17 years, the overall distribution of these alkaloid types within the family has changed little since the chemosystematics reviews by Waterman (270), Mester (40), and da Silva et al. (279). Alkylquinolones dominate the reported isolations with about 51% of the total, with arylquinolones (16%), alkylquinolines (15%), alkylarylquinolines (11%), arylquinolines (3%), alkylarylquinolones (2%), and quinolines (2%) as the significant structural groups contributing to the remainder of this class of alkaloids. The alkyl-, aryl-, and alkylarylquinolin/one alkaloids occur in 50 species belonging to 24 genera and 6 subfamilies. Despite the intensive chemical exploration of many species from other plants in the Rutales family, but not in the family Rutaceae, the first alkaloid alkylquinolone from a simaroubaceous plant (160) was not reported until 1997. Although many additional alkaloids have been reported, some of new structural types (Bo.4), substantial biosynthetic work on plant-derived alkylquinolin/ones has not yet been carried out. The biosynthesis of some of these alkaloids in bacteria was firmly established as being derived from anthranilic acid. Outside of the Rutales, alkyl-, aryl-, and alkylarylquinolin/ones have not been found, except for simple quinoline (A.1; only one) and 2-methylquinoline derivatives in the Zygophyllaceae, and only an atypical quinolone derivative (Ao.1) in the Asteraceae family. A few 3-phenylquinolines (2), 3-(1H-indol-3-yl)quinoline (1), and quinoline-quinazoline (1) alkaloids have been reported from only a single genus in the Zygophyllaceae. Tryptophan-derived quinolines in higher plants are confined to a few 2-carboxylicquinolin/ones (6) and 4-carbaldehydequinolines (5); the former found in the Ephedraceae (5), Boraginaceae (1), Fagaceae (1), Ginkgoaceae (1), Plumbaginaceae (1), Solanaceae (1), and Apiaceae (1), and the latter in the Moraceae (3), Alliaceae (1), and Pontederiacae (1). The number of quinolones derived from glycine and a polyketide is also limited. 5-Alkyl-2-methylquinolin-4(1H)-ones (8) occur in the Euphorbiaceae, and 5-alkyaryl-2-methylquinolin-4(1H)-ones ((3) in the Sterculiaceae. Alkylquinolin/ones are well-known as typical alkaloids of three Proteobacteria and three Actinobacteria; the genus Pseudomonas yielded the majority (46%) of the total number of alkaloids reported (39). 2-Carboxylicquinolin/ones (4) and 4-carbaldehydequinolines (6) are minor constituents in both divisions of bacteria. More interesting are the quinolactacins (7), in which the second nitrogen is derived from L-valine or L-isoleucine, recently reported to occur only in the fungus Penicillium. Many of these diverse alkaloids have served directly as medicines or as lead compounds for the synthesis (258) of derivatives with an improved biological profile. It is apparent from the summary view of the alkyl-, aryl-, and alkylarylquinolin/ones reported in the Rutaceae that they help to confirm the affinity between Rutoideae tribes and provide firm support for placing the Spathelioideae and the Dictyolomatoideae close to the more primitive Zanthoxyleae tribe. On the other hand, the bacteria and fungi are needed for more substantial chemical studies. When more data become available, it is likely that useful systematic correlations will emerge. More detailed studies regarding the biosynthetic pathways of the alkyl-, aryl-, and alkylarylquinolin/ones in the Rutaceae and in bacteria are needed. Such studies would clarify the differences in the pathways based on their derivation from anthranilic acid in bacteria and in rutaceous plants. Finally, this survey indicates that the Rutaceae, and various bacterial and fungal species offer considerable potential for the discovery of new or known alkaloids with significant and possibly valuable biological activities.

Abstract
A regioselective quinazolinone-directed ortho lithiation on an adjacent quinoline moiety has been used as a key step for a short, efficient, and practical synthesis of the human DNA topoisomerase I poison luotonin A and luotonins B and E. The quinazolinoylquinoline 5 on treatment with in situ-generated nonnucleophilic mesityllithium furnished the desired dilithiated intermediate 6, which on treatment with formaldehyde followed by Mitsunobu ring closure reaction gave luotonin A (1a) in very good yield. The reaction of dilithiated intermediate 6 with DMF directly furnished luotonin B (1b) in 81% yield. Luotonin B (1b) on methylation with p-TSA/methanol gave luotonin E (1c) in 82% yield.

Abstract
An alkaloidal extract of the stem barks of Zanthoxylum chiloperone var. angustifolium exhibited antifungal activity against Candida albicans, Aspergillus fumigatus and Trichophyton mentagrophytes var. interdigitale using a TLC bioautographic method. Bioassay-guided fractionation of this extract resulted in the isolation of two active compounds identi fi ed as canthin-6-one and 5-methoxycanthin-6-one. Canthin-6-one exhibited a broad spectrum of activities against Aspergillus fumigatus, A. niger, A. terreus, Candida albicans, C. tropicalis, C. glabrata, Cryptococcus neoformans, Geotrichum candidum, Saccharomyces cerevisiae, Trichosporon beigelii, Trichosporon cutaneum and Trichophyton mentagrophytes var. interdigitale with MICs values between 5.3 and 46 micro mol/L. 5-methoxy-canthin-6-one was active against only Trichophyton mentagrophytes var. interdigitale with a MIC value of 12.3 micro mol/L.

Abstract
The crude alkaloidal extract of Zanthoxylum chiloperone stem bark exhibited in vitro activity against various strains of Leishmania ssp. at 100 microg/ml. Two active major constituents were isolated and identified as canthin-6-one and 5-methoxycanthin-6-one. The effect of these compounds was also tested in an in vivo assay using BALB/c mice infected with Leishmania amazonensis. The mice were treated for 5 weeks postinfection with these alkaloids by oral (14 days) or intralesional route (4 days) at 10 mg/kg daily. The reference drug, N-methylglucamine antimonate was administered by subcutaneous injections at 100 mg/kg for 10 days. Intralesional administration of canthin-6-one reduced the parasite burden but not significantly when it was compared with the untreated group, while the reference drug reduced by 91% the parasite loads in the lesion.
