Abstract
Herein, we report the development of a diastereoselective and efficient route to construct sugar-derived pyrano[3,2-c]quinolones utilizing 1-C-formyl glycal and 4-hydroxy quinolone annulation. This methodology will open a route to synthesize nature inspired pyrano[3,2-c]quinolones. This is the first report for the stereoselective synthesis of sugar-derived pyrano[3,2-c]quinolones, where 100% stereoselectivity was observed. A total of sixteen compounds have been synthesized in excellent yields with 100% stereoselectivity. The molecular docking of the synthesized novel natural product analogues demonstrated their binding modes within the active site of type II topoisomerase. The results of the in-silico studies displayed more negative binding energies for the all the synthesized compounds in comparison to the natural product huajiosimuline A, indicating their affinity for the active pocket. Ten out of the sixteen novel synthesized compounds were found to have comparative or relatively more negative binding energy in comparison to the standard anti-cancer drug, doxorubicin. Additionally, the scalability and viability of this protocol was illustrated by the gram scale synthesis.

Abstract
Phosphodiesterases (PDEs) are vital in signal transduction, specifically by hydrolyzing cAMP and cGMP. Within the PDE family, PDE10A is notable for its prominence in the striatum and its regulatory function over neurotransmitters in medium-spiny neurons. Given the dopamine deficiency in Parkinson's disease (PD) that affects striatal pathways, PDE10A inhibitors could offer therapeutic benefits by modulating D1 and D2 receptor signaling. This study was motivated by the successful history of quinazoline/quinazoline scaffolds in the inhibition of PDE10A. This study involved detailed in silico evaluations through docking followed by pharmacological, pharmacophoric, and pharmacokinetic analyses, prioritizing central nervous system (CNS)-active drug criteria. Seven cyclic peptides, those featuring the quinazoline/quinazoline moiety at both termini, exhibited notably enhanced docking scores compared to those of the remaining alkaloids within the screened library. We identified 7 quinolines and 1 quinazoline including Lepadin G, Aspernigerin, CJ-13536, Aurachin A, 2-Undecyl-4(1H)-quinolone, Huajiaosimuline 3-Prenyl-4-prenyloxyquinolin-2-one, and Isaindigotone that followed the standard CNS active drug criteria. The dominant quinoline ring in our study and its related quinazoline were central to our evaluations; therefore, the pharmacophoric features of these scaffolds were highlighted. The top alkaloids met all CNS-active drug properties; while nonmutagenic and without PAINS alerts, many indicated potential hepatotoxicity. Among the compounds, Huajiaosimuline was particularly significant due to its alignment with lead-likeness and CNS-active criteria. Aspernigerin demonstrated its affinity for numerous dopamine receptors, which signifies its potential to alter dopaminergic neurotransmission that is directly related to PD. Interestingly, the majority of these alkaloids had biological targets primarily associated with G protein-coupled receptors, critical in PD pathophysiology. They exhibit superior excretion parameters and toxicity end-points compared to the standard. Notably, selected alkaloids demonstrated stability in the binding pocket of PDE10A according to the molecular dynamic simulation results. Our findings emphasize the potential of these alkaloids as PDE10A inhibitors. Further experimental studies may be necessary to confirm their actual potency in inhibiting PDE10A before exploring their therapeutic potential in PD.

Abstract
Zanthoxylum bungeanum Maxim. has been included in "The Plant List" (http://www.theplantlist.org) is a plant of the Rutaceae family of Zanthoxylum bungeanum, also named Chinese prickly ash. It is a resource for both medicinal and edible reasons. Traditional Chinese medicine claims that its main functions are: warming, and easing pain, destroying insects and soothing itching. Modern study has established that it possesses anti-inflammatory, antibacterial, insecticidal, anti-tumor, and other pharmacological characteristics effect. As a traditional condiment, Chinese prickly ash is the soul of Sichuan cuisine. Its numb flavor is the main characteristic and one crucial indicator of its quality. Studies have proven that the numb flavor of Chinese prickly ash stems from its abundant volatile oil. The research on the exact components of its volatile oil is becoming a hot spot. Sichuan, the central core-producing area of Chinese prickly ash, cultivates numerous species of prickly ash and is rich in resources. By planting Chinese prickly ash, the income level of local farmers has been enhanced, the villagers' quality of life has been considerably improved, and poverty has been lifted. This study briefly explains the planting status and production area distribution of prickly ash in Sichuan Province and reviews the recent research on the chemical components, volatile oil extraction methods, pharmacological effects, etc. Reasonable development prospects are projected to reference the in-depth research of prickly ash, the development and usage of resources, and the development of associated items.

Abstract
AbstractIn this work, new chitosan-based Schiff bases were synthesized by the reaction of chitosan with quinolinone and pyranoquinolinone giving CSQ, and CSP, respectively. The novel Chitosan Schiff bases were grafted on silver nanoparticles providing CSQ/Ag, CSP/Ag structures. Characterization of isolated compounds was carried out by FT-IR, TGA, XRD, SEM, and TEM. The target compounds CSQ, CSP, CSQ/Ag, and CSP/Ag were evaluated as antitumor agents against three cancer cell lines, liver (HepG-2), colon (HCT-116), and breast (MCF-7). Compound CSQ/Ag disclosed potent cytotoxic effect with IC50 values in the range of 41.9–55.1 μg/ml in comparison with 5-fluorouracil against different cancer cell lines. Besides, the antioxidant activity of chitosan and its quinolinone and pyranoquinolinone analogues was assessed as radical scavengers versus 1,1-diphenyl-2-picrylhydrazyl radicals (DPPH%). The compound CSQ/Ag emerged as the most active member in scavenging the DPPH radicals. The obtained findings proved that the new Schiff bases/silver nanoparticles of chitosan showed higher antiproliferative and antioxidant activities than the blank CS and would be highly applicable in biomedical fields.

Abstract
A series of 1,3-cyclodiketone- and tetrahydroepoxyisoindole-fused β-enamino dicarbonyl heterocycles were synthesized via a 1,4-diazabicyclo[2.2.2]octane-catalyzed, CH3NO2-mediated three-component reaction of 1,3-cyclodiketone, furfural, and allylamine in toluene. The target compounds were generated via the formation of β-enamino diketone as a key intermediate, followed by intramolecular Diels-Alder cycloaddition. The prepared molecules bearing a quinoline-2,4-dione moiety could be further brominated with N-bromosuccinimide and diastereoselectively reduced by NaBH4 to afford pyrano[3,2-c]quinolin-5-one-derived heterocycles with six vicinal stereogenic centers.

Abstract
Two acid-catalyzed tandem reactions between 4-hydroxy-1-methylquinolin-2(1H)-one and propargylic alcohols are described. Depending mainly on the propargylic alcohol used, these tandem reactions proceed via either a Friedel–Crafts-type allenylation followed by 6-endo-dig cyclization sequence to form pyrano[3,2-c]quinolones or a Friedel–Crafts-type alkylation and 5-exo-dig ring closure sequence to afford furo[3,2-c]quinolones in moderate-to-high yields. The pyrano[3,2-c]quinolones products could be further transformed to tetracyclic 4,9-dihydro-5H-cyclopenta[lmn]phenanthridin-5-one derivatives. Two acid-catalyzed tandem reactions between 4-hydroxy-1-methylquinolin-2(1H)-one and propargylic alcohols are described.![]()

It is de-regulated in several cancers, including breast cancer, where it is highly expressed and phosphorylated. Thus, targeting Src by a small molecule is a feasible strategy for managing different breast cancer types. Several Src kinase inhibitors are available, including the FDA-approved drug (dasatinib). However, they are primarily ATP-competitive inhibitors that have been reported to lack specificity towards Src. We have a long-time interest in discovering protein kinase inhibitors that are non-competitive for ATP. In this project, three groups of 2'-aminospiro[pyrano[3,2-c]quinoline]-3'-carbonitrile derivatives were designed and synthesized, hypothesizing that small molecules with a spiro scaffold appended to a pyrano[3,2-c]quinoline analog could act as non-ATP competitive Src kinase inhibitors. 3b, 3c, and 3d inhibited Src kinase activity with IC50s of 4.9, 5.9, and 0.9 μM, respectively. At the same time, they did not impact the MDM2/p53 interaction in HEK293 cells, which has been reported to be affected by some spirocyclic compounds. 25 µM of 3b, 3c, or 3d did not inhibit the kinase activity of ERK2, JNK1, or p38-alpha in an in-vitro kinase assay. Steady-state kinetic studies for the effect of 3d on the ability of recombinant Src to phosphorylate its substrate (Srctide) revealed a non-ATP competitive inhibition mechanism. 1.6 µM of 3d was enough to diminish Src, Fak, and paxillin phosphorylation in the breast cancer cell lines MDA-MB-231 and MCF7. In the NCI screening, 3d induced broad tumor cytotoxicity for the NCI-60 cell lines, including all the breast cancer cell lines. The potency of 3b, 3c, and 3d to inhibit migration, proliferation, and colony formation of MDA-MB-231 and proliferation of MCF7 cells correlates with their potency to suppress Src kinase activity in the same cell line. Noticeably, the cell growth suppression and apoptosis induction in the tested cell lines can be attributed to the ability of the new derivatives to suppress the ERK and Akt survival pathways downstream of Src.

Abstract
INTRODUCTION Quaternary alkaloids (QAs) are the major alkaloids in several traditional Chinese medicines, especially in Zanthoxylum simulans. However, few studies on enrichment of QAs from Z. simulans were conducted due to their high polarity and low content. OBJECTIVE To develop a weak cation exchange (WCX) solid-phase extraction (SPE) coupled with liquid chromatography mass spectrometry (LC-MS) method to enrich and identify QAs from Z. simulans. Meanwhile, the qualitative and quantitative analyses of QAs were carried out based on the optimum conditions of the method. METHODS Fresh stem bark of Z. simulans was extracted with 70% aqueous methanol and enriched by WCX-SPE. A high-performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS) with an electrospray ionisation (ESI) source was used for the qualitative and quantitative analyses of QAs. RESULTS Significant improvements were observed in resolution and abundance of the peaks with WCX-SPE. The linearity, limit of detection (LOD) and limit of quantification (LOQ) were determined for this analytical method. The linear relationship (A = 338.85C - 187.72, R2 = 0.99) was explored in the range of 0.5 to 312.5 μg/mL for chelerythrine. The LOD and LOQ for chelerythrine standard solutions were 0.0539 μg/mL and 0.1798 μg/mL, respectively. In addition, 22 peaks were detected successfully with WCX-SPE and nine of them are undetectable without the processing of WCX-SPE. CONCLUSION A highly selective and efficient method for simultaneous enrichment and identification of QAs from crude extract of Z. simulans was developed for the first time by combining WCX-SPE with LC-MS.

Abstract
Background:
Quinoline analogues exhibited diversified biological activities depending on the structure
type. A number of natural products with pyrano[3,2-c]quinolone structural motifs and patented chromenes
were reported as promising cytotoxic agents.
Objective:
The present study is aimed to evaluate a new series of pyrano[3,2-c]quinoline scaffolds derived from
the fusion of bioactive quinolone pharmacophore with structurally diverse aryl substituted chromene for its
cytotoxicity.
Methods:
A library of pyrano[3,2-c]quinoline analogues was prepared from one-pot multi component synthesis
using various aromatic aldehydes, malononitrile and 2,4-dihydroxy-1-methylquinoline. The new synthetics were
primarily screened for its cytotoxicity (IC50) against different human cancer cell lines in vitro. The promising
synthetics were further evaluated in vitro for their potency against different kinase activity. The promising compounds
were finally tested for their in vivo efficacy in SCID type mice HCT-116 tumor model.
Results:
The screening results revealed that compounds 4c, 4f, 4i and 4j showed promising activity in in vitro
study. However, compound 4c was found to be the most potent candidate with 23% tumor growth inhibition in
HCT-116 tumor mice model.
Conclusion:
The structure activity relationship suggested that 3-substitution on the aryl ring at C4 position of
the pyrano[3,2 c]quinolone moiety seems to have an important position for cytotoxicity activity. However, 3-
chloro substitution at C4 aryl ring showed a significant alteration of the bioactive conformer of the parent scaffold
and outcome with compound 4c as the most potent candidate of the series.

Abstract
Natural products (NPs) are important sources of clinical drugs due to their structural diversity and biological prevalidation. However, the structural complexity of NPs leads to synthetic difficulties, unfavorable pharmacokinetic profiles, and poor drug-likeness. Structural simplification by truncating unnecessary substructures is a powerful strategy for overcoming these limitations and improving the efficiency and success rate of NP-based drug development. Herein, we will provide a comprehensive review of the structural simplification of NPs with a focus on design strategies, case studies, and new technologies. In particular, a number of successful examples leading to marketed drugs or drug candidates will be discussed in detail to illustrate how structural simplification is applied in lead optimization of NPs.

Abstract
A series of novel pyranoquinolinone-based Schiff's bases were designed and synthesized. They were evaluated for topoisomerase IIβ (TOP2B) inhibitory activity, and cytotoxicity against breast cancer cell line (MCF-7) for the development of novel anticancer agents. A molecular docking study was employed to investigate their binding and functional properties as TOP2B inhibitors, using the Discovery Studio 2.5 software, where they showed very interesting ability to intercalate the DNA-topoisomerase complex. Compounds 2a, 2c and 2f showed high docking score values (82.36% -29.98 kcal mol-1 for compound 2a, 78.18% -26.98 kcal mol-1 for compound 2c and 78.65, -28.11 kcal mol-1 for compound 2f) and revealed the highest enzyme inhibition activity. The best hit compounds exhibited highly potent TOP2B inhibitors with submicromolar IC50 at 5 µM compared to the reference doxorubicin.

Abstract
BACKGROUND To investigate the antidiabetic effect of Himalayan Medicinal plants from India viz. Melia azedarach (Family: Meliaceae), Zanthoxylum alatum (Family: Rutaceae), Tanacetum nubigenum (Family: Asteraceae) using in-vitro as well as in-vivo approaches. METHODS Their effects were examined on stimulation of glucose uptake by C2C12 cultured cell line, inhibitory effect on human recombinant Protein tyrosine phosphatase-1B (PTP-1B) and followed by the hypoglycaemic activity of extracts in Streptozotocin (STZ) induced diabetic rats. RESULTS All prepared extracts had been found to enrich with polyphenolic, flavonoids, terpenoids, anthraquinones and saponins type of compounds. n-Butanol fraction of Zanthoxylum alatum showed maximum PTP-1B inhibition (61.9%) whereas ethanol extract of Tanacetum nubigenum showed strong stimulation of glucose uptake (+61.2%) in C2Cl2 myotubes. In STZ induced Sprague-Dawley rats, significant decrease in blood glucose level was observed in ethanol extract of Melia azaderach treated group as 14.8% (p < 0.01) whereas in the ethanol extract of Tanacetum nubigenum treated group, it was observed as 15.5% (p < 0.01) compare to metformin which showed 26.8% (p < 0.01) lowering of blood glucose in the same time duration of 5 h study. CONCLUSION This study demonstrated that these plants have a significant therapeutic value in type-2-diabetes mellitus and related complications thus supporting their traditional uses in Indian traditional system of medicine.

Abstract
Quinoline and quinazoline alkaloids, two important classes of N-based heterocyclic compounds, have attracted tremendous attention from researchers worldwide since the 19th century. Over the past 200 years, many compounds from these two classes were isolated from natural sources, and most of them and their modified analogs possess significant bioactivities. Quinine and camptothecin are two of the most famous and important quinoline alkaloids, and their discoveries opened new areas in antimalarial and anticancer drug development, respectively. In this review, we survey the literature on bioactive alkaloids from these two classes and highlight research achievements prior to the year 2008 (Part I). Over 200 molecules with a broad range of bioactivities, including antitumor, antimalarial, antibacterial and antifungal, antiparasitic and insecticidal, antiviral, antiplatelet, anti-inflammatory, herbicidal, antioxidant and other activities, were reviewed. This survey should provide new clues or possibilities for the discovery of new and better drugs from the original naturally occurring quinoline and quinazoline alkaloids.

Abstract
A series of pyrano[3,2-c]quinoline based structural analogues was synthesized using one-pot multicomponent condensation between 2,4-dihydroxy-1-methylquinoline, malononitrile, and diverse un(substituted) aromatic aldehydes. The synthesized compounds were evaluated for their anti-inflammatory and cytotoxicity activity. Initially, all the compounds were evaluated for the percent inhibition of cytokine release, and cytotoxicity activity and 50% inhibitory concentrations (IC50) were also determined. Based on the primary results, it was further studied for their ability to inhibit TNF-α production in the human peripheral blood mononuclear cells (hPBMC) assay. The screening results revealed that compound 4c, 4f, 4i, and 4j were found most active candidates of the series against both anti-inflammatory and anticancer activity. The structure-activity relationship is discussed and suggested that 3-substitution on the aryl ring at C4 position of the pyrano[3,2-c]quinolone structural motif seems to be an important position for both TNF-α and IL-6 inhibition and anticancer activity as well. However, structural diversity with electron withdrawing, electron donating, sterically hindered, and heteroaryl substitution sincerely affected both the inflammation and anticancer activities.

Abstract
Background Zanthoxylum armatum DC has been an important traditional plant known for its medicinal properties. It is well known for its antimicrobial, larvicidal and cytotoxic activities. Methods The potential anticancer effects of the methanol extract and the crude saponins from fruit, bark and leaves of Z. armatum on breast (MDA-MB-468 and MCF-7) and colorectal (Caco-2) cancer cell lines using MTT, neutral red uptake(NRU) and DAPI stain assays were evaluated. Results In MTT assay the methanol extract of fruit (Zf), bark (Zb) and leaves (Zl) of Zanthoxylum armatum, showed significant and dose dependent growth inhibition of MCF-7, MDA MB-468 and Caco-2 cancer cell lines in a dose of 200 μg/ml and above. The saponins (Zf.Sa, Zb.Sa and Zl.Sa) showed significant activity against MDA MB-468 (95, 94.5 and 85.3%) as compared to MCF-7 (79.8, 9.43, 49.08%) and Caco-2 (75.8, 61.8, 68.62%) respectively. The extracts were further tested in more sensitive NRU assay and its was found that Zf extract showed higher cytotoxic activity as compared to Zb and Zl extracts with 100 μg/ml concentration. The breast cancer cell lines showed more sensitivity toward the crude saponins from fruit and bark with maximum inhibition of up to 93.81(±2.32) % with respect to 71.19(± 2.76) of Actinomycin-D. DAPI staining experiment showed that saponins from fruit induced apoptosis mode of cell death in all three types of cell lines while saponins form leaves and bark showed similar results against MDA MB-468 indicated by nuclear fragmentation and chromatin condensation. The effect of saponins from fruit, bark and leaves (Zf.Sa, Zb.Sa and Zl.Sa) against Caco-2 cell lines inhibited the growth of Caco-2 by 53.16 (±3.31) %, 66.43 (± 3.24) and 45.96 (± 10.67) respectively with respect to Actinomycin-D (4 μM) which showed the growth inhibition of 65.40(±4.29) %. Conclusion The current study clearly demonstrates that the extract and crude saponins from fruit, bark and leaves of traditional medicinal plant Zanthoxyllum armatum DC., has the potential to exert its cytotoxic effect on cancer cell lines isolated form human by a mechanism involving apoptosis. The overall finding demonstrate that this plant specially fruits, could be potential source of new anticancer compounds for possible drug development against cancer.

Abstract
A new class of pyrazolo[4,3-c]quinoline (5a-i, 7a-b) and pyrano[3,2-c]quinoline (9a-i) derivatives were designed and synthesized in moderate to good yields by microwave conditions. To enhance the yield of pyrano[3,2-c]quinoline derivatives, multicomponent one-pot synthesis has been developed. The synthesized compounds were identified by spectral and elemental analyses. Compounds 9a and 9i showed good antibacterial activity against Gram-positive and Gram-negative bacterial strains. All of the new compounds exhibited weak to moderate antioxidant activity, compound 9d exerted significant antioxidant power. The cytotoxicity of these compounds were also evaluated against MCF-7 (breast) and A549 (Lung) cancer cell lines. Most of the compounds displayed moderate to good cytotoxic activity against these cell lines. Compound 9i was found to be significantly active in this assay and also induced cell death by apoptosis. Molecular docking studies were carried out using EGFR inhibitor in order to determine the molecular interactions.

Abstract
Zanthoxylum armatum fruits are used traditionally as a spice in various food preparations. The aim of this study was analysis of antimicrobial, cytotoxic, phytotoxic, insecticidal, and anti-leishmanial activity. The crude extract showed 86 ± 10% antifungal activity (Agar tube dilution method) against Trichophyton longifusis while n-hexane, chloroform, and aqueous-methanol fractions inhibited this pathogen by 90 ± 7, 85 ± 10 and 70 ± 9% respectively. The n-hexane and aqueous-methanol fraction also, respectively, showed 40 ± 10 and 87 ± 9% inhibition of Microsporum canis. Chloroform fraction also displayed antifungal activity against Aspergillus flavus (60 ± 10%) and aqueous-methanol fraction against F. solani (40 ± 8%). The crude ethanolic extract and its chloroform and aqueous-methanol fraction exhibited significant toxicity (Brine shrimps lethality assay) against brine shrimps having LC50 value of 6.66 ± 1.1, 21.4 ± 3.3 and 29.6 ± 3.9 μg/ml, respectively. The crude ethanolic extract and its n-hexane soluble portion exhibited good anti-leishmanial activity (well serial dilution method) each having IC50 values of 50 ± 5 μg/ml. The crude extract and various fractions possessed excellent herbicidal activity (Lemna minor assay), and caused more than 90% inhibition of the plant growth at 1000 μg/mL. The ethanolic extract, n-hexane and chloroform soluble portions caused 90% mortality in insecticidal activity (direct contact method) of Rhyzopertha dominica. The ethanolic extract and its n-hexane soluble portion, respectively, caused 80 and 90% mortality of Callosobruchus analis. The present study showed that the tested fruit extracts of Z. armatum exhibited strong antifungal, cytotoxic, phytotoxic, insecticidal, and anti-leishmanial effects.
