Abstract
A facile and direct intramolecular indolinone-quinolone rearrangement was developed for the synthesis of quinolino[3,4-b]quinoxalin-6-ones from spiro[indoline-3,2'-quinoxaline]-2,3'-diones, which are readily available with use of isatines, malononitrile, and 1,2-phenylenediamines under quite mild conditions. This efficient approach provides excellent yields and could potentially be used for the construction of a diverse library of quinolino[3,4-b]quinoxalin-6-ones for high-throughput screening in medicinal chemistry. The reaction mechanism is explored by extensive DFT calculations.

Abstract
A metal-free C-H [5 + 1] annulation reaction of 2-arylanilines with diazo compounds has been achieved, giving rise to two types of prevalent phenanthridines via highly selective C-C cleavage. Compared to the simple N-H insertion manipulation of diazo, this method elegantly accomplishes a tandem N-H insertion/SEAr/C-C cleavage/aromatization reaction, and the synthetic utility of this new transformation is exemplified by the succinct syntheses of trisphaeridine and bicolorine alkaloids.

Abstract
The association of a putative bioactive alkaloid nitidine (NIT) with blood protein bovine hemoglobin (BHb) was investigated by employing various biophysical and molecular docking techniques. NIT binding to BHb was first characterized by hypochromic effect on the Soret band absorption of BHb from spectrophotometric studies. Spectrofluorimetric titration and unchanged fluorescence lifetime of BHb confirmed ground state complexation followed by the static nature of the emission quenching mechanism of the protein induced by NIT. Substantial conformational changes in the protein structure were established from circular dichroism study. Conformational perturbation results a lowering in the α-helical organization of the tetrameric protein structure. Thermodynamics of the binding suggest that the binding is exothermic with a favourable small positive entropy change and negative enthalpy change making a sense of electrostatic interaction as the major acting force. Experimentally calculated free energy change for the NIT-BHb interaction was found to be -7.50 kcal mol-1 which is in well agreement to the theoretical docking energy value of -6.36 kcal mol-1. AutoDock based molecular docking suggests the internal cavity of BHb as the preferred binding position of NIT. Overall this manuscript depicts consequences on the molecular interaction of NIT with BHb from structural and energetic standpoints providing a profound insight into protein-ligand association.

Abstract
Context: The resistance of Plasmodium species to many available antimalarials calls for a continuous search for newer antimalarial agents. One possible source of new antimalarials is from natural sources such as Fagara zanthoxyloides Lam (Rutaceae), a medicinal plant used traditionally for treating malaria in South-Eastern Nigeria, Uganda and Asia. Objectives: To investigate the application of methanol extracts of F. zanthoxyloides in combating malaria infection and its associated disorders. Materials and methods: Methanol extracts of F. zanthoxyloides leaves (MEFZ) were evaluated for in vivo antimalarial activity. MEFZ at doses of 200, 400, and 600 mg/kg/d were administered orally for 4 consecutive days (days 0-4) to P. berghei-infected mice. The possible ameliorative effects of MEFZ on malaria-associated organ malfunctions were also assessed. Results: At 200, 400 and 600 mg/kg b.w., respectively, MEFZ produced 82.37% and 68.39%, 84.84%, and 90.75%, 95.95% and 92.67% chemosuppression and inhibition of P. berghei, respectively, comparable to 98.67% and 97.29% by combisunate, a standard antimalarial. The IC50 of MEFZ was estimated to be 235.23 mg/kg b.w. Similarly, treatment of parasitized mice with MEFZ significantly restored the malaria-modified haematological and biochemical status of the parasitized-MEFZ-treated mice compared with parasitized-untreated mice. MEFZ was tolerable up to 5000 mg/kg b.w dose; hence, the LD50 is above 5000 mg/kg b.w. Discussion and conclusions: The results of this curative assay demonstrated that MEFZ has antimalarial effects and normalized haematological and biochemical aberrations generated by malaria. The isolation of the antimalarial principles in MEFZ is warranted; they could be lead molecules for the development of new antimalarials.

Abstract
The aim of the present study was to determine the role of topoisomerase 1 (TOP1) and topoisomerase 2A (TOP2A) in liver cancer (LC), and to investigate the inhibitory effect of nitidine chloride (NC) on these two topoisomerases. Immunohistochemistry (IHC) staining and microarray or RNA sequencing data mining showed markedly higher expression of TOP1 and TOP2A at the protein and mRNA levels in LC tissues compared with that in control non-tumor tissues. The prognostic values of TOP1 and TOP2A expression were also estimated based on data from The Cancer Genome Atlas. The elevated expression levels of TOP1 and TOP2A were closely associated with poorer overall survival and disease-free survival rates. When patients with LC were divided into high- and low-risk groups according to their prognostic index, TOP1 and TOP2A were highly expressed in the high-risk group. Bioinformatics analyses conducted on the co-expressed genes of TOP1 and TOP2A revealed that the topoisomerases were involved in several key cancer-related pathways, including the 'p53 pathway', 'pathway in cancer' and 'apoptosis signaling pathway'. Reverse transcription-quantitative polymerase chain reaction and IHC performed on triplicate tumor tissue samples from LC xenografts in control or NC-treated nude mice showed that NC treatment markedly reduced the protein and mRNA expression of TOP1 and TOP2A in LC tissues. Molecular docking studies further confirmed the direct binding of NC to TOP1 and TOP2A. In conclusion, the present findings indicate that TOP1 and TOP2A are oncogenes in LC and could serve as potential biomarkers for the prediction of the prognosis of patients with LC and for identification of high-risk cases, thereby optimizing individual treatment management. More importantly, the findings support TOP1 and TOP2A as potential drug targets of NC for the treatment of LC.

Abstract
Traditional Chinese medicines (TCMs) have important therapeutic value in long-term clinical practice. However, because TCMs contain diverse ingredients and have complex effects on the human body, the molecular mechanisms of TCMs are poorly understood. In this work, we determined the gene expression profiles of cells in response to TCM components to investigate TCM activities at the molecular and cellular levels. MCF7 cells were separately treated with 102 different molecules from TCMs, and their gene expression profiles were compared with the Connectivity Map (CMAP). To demonstrate the reliability and utility of our approach, we used nitidine chloride (NC) from the root of Zanthoxylum nitidum, a topoisomerase I/II inhibitor and α-adrenoreceptor antagonist, as an example to study the molecular function of TCMs using CMAP data as references. We successfully applied this approach to the four ingredients in Danshen and analyzed the synergistic mechanism of TCM components. The results demonstrate that our newly generated TCM data and related methods are valuable in the analysis and discovery of the molecular actions of TCM components. This is the first work to establish gene expression profiles for the study of TCM components and serves as a template for general TCM research.

Abstract
Nitidine chloride (NC), a bioactive alkaloid isolated from Zanthoxylum nitidum, has been used as a herbal ingredient in toothpaste that prevents cavities for decades. It also displays potential antitumor and anti-inflammation properties. However, its anticatabolic effect on bone is not known. We investigated the effect of NC on osteoclastogenesis, bone resorption and RANKL-induced NF-κB and NFATc1 signalling. In mouse-derived bone marrow monocytes (BMMs), NC suppressed RANKL-induced multinucleated tartrate-resistant acid phosphatase (TRAP)-positive osteoclast formation and bone resorption in a dose dependent manner. NC attenuated the expression of osteoclast marker genes including cathepsin K, D2, calcitonin receptor, NFATc1, and TRAP. Further, NC inhibited RANKL-activated NF-κB and NFATc1 signalling pathways. In vivo study revealed that NC abrogated oestrogen deficiency-induced bone loss in ovariectomized mice. Histological analysis showed that the number of osteoclasts was significantly lower in NC-treated groups. Collectively, our data demonstrate that NC suppressed osteoclastogenesis and prevented OVX-induced bone loss by inhibiting RANKL-induced NF-κB and NFATc1 signalling pathways. NC may be a natural and novel treatment for osteoclast-related bone lytic diseases.

Abstract
A study concerning design, synthesis, structure and in vitro antimycobacterial and anticancer evaluation of new fused derivatives with pyrrolo[2,1-c][4,7]phenanthroline skeleton is described. The strategy adopted for synthesis involves a [3 + 2] dipolar cycloaddition of several in situ generated 4,7-phenanthrolin-4-ium ylides to different substituted alkynes and alkenes. Stereo- and regiochemistry of cycloaddition reactions were discussed. The structure of the new compounds was proven unambiguously, single-crystal X-ray diffraction studies including. The antimycobacterial and anticancer activity of a selection of new synthesized compounds was evaluated against Mycobacterium tuberculosis H37Rv under aerobic conditions and 60 human tumour cell line panel, respectively. Five of the tested compounds possess a moderate antimycobacterial activity, while two of the compounds have a significant antitumor activity against renal cancer and breast cancer.

Abstract
We report herein a feasible study concerning the design, synthesis, structure and in vitro antimycobacterial and anticancer activity of two new classes (containing four and five fused rings) of indolizine with phenanthroline skeleton. The preparation is straight and efficient, involving a Huisgen [3+2] dipolar cycloaddition of cycloimmonium ylides to alkynes or alkenes dipolarophiles. The cycloaddition reactions are highly stereo- or regioselective, according with the dipolarophiles nature. The structure of the new compounds was assigned unambiguously, X-ray analysis including. The primary antimycobacterial screening reveals that one of the thirteen tested compounds had a good activity against Mycobacterium tuberculosis H37Rv under aerobic conditions. The antiproliferative evaluation against a NCI 60 human tumor cell line panel, revealed that two indolizine with phenanthroline skeleton exhibit a selective and significant antitumor growth inhibitory activity against Breast Cancer (MCF7 and T-47D) and a slightly moderate activity against some forms of Leukemia, Non-Small Cell Lung Cancer, Renal Cancer and Breast Cancer (MDA-MB-468). The X-ray diffraction study of the indolizines with phenanthroline skeleton prove a flat coplanar structure which, corroborated with their anticancer activity, allow us to suggest that an interaction with DNA (via an intercalation mechanism) would be reasonable.

Abstract
A novel procedure for hydride-induced anionic cyclization has been developed. It includes the reduction of a biaryl bromo-nitrile with a nucleophilic aromatic substitution (S(N)Ar). A range of polysubstituted 6-H-phenanthridines were so obtained in moderate to good yield with good substrate tolerance. This method involves a concise transition-metal-free process and was applied to synthesize natural alkaloids.

Recently, a number of compounds with biological and pharmacological activities have been extracted from the plant and used as chemotherapeutic candidates to treat a range of diseases such as cancer. OBJECTIVE The current study was designed to isolate the alkaloid compounds from ethyl acetate extraction of Broussonetia papyrifera fruits, and to evaluate the cytotoxic activity of total alkaloids as well as individual isoquinoline alkaloids from B. papyrifera fruits. METHODS Alkaloid compounds were isolated from the ethyl acetate extraction by silica gel column chromatography methods using CHCl3/MeOH as eluents. The compounds' structures were determined by detailed analysis of NMR, MS spectral data, and chemical methodology. Cytotoxic activity was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) methods against human A375, Hela, BEL-7402 cancer cells, and non-cancer cells. RESULTS Two isoquinonline alkaloids were isolated and characterized as N-norchelerythrine and dihydrosanguinarine. The total alkaloids and seven individual alkaloids had higher activities on BEL-7402 and Hela cell lines with low IC50 values 6.61-47.41 and 5.97-40.17 μg/mL (<50 μg/mL). Nitidine, broussonpapyrine, and chelerythrine had strong toxic on non-cancer cells with IC50 value 18.01, 19.91, and 22.31 μg/mL, respectively. DISCUSSION N-Norchelerythrine and dihydrosanguinarine were isolated from this plant for the first time. Our data implicated that seven isoquinoline alkaloids had cytotoxity with structure-activity relationships, which provided fundamental information for further modification of their anticancer effect.

Abstract
Benzophenanthridine alkaloids represent a very interesting and significant group of natural products that exhibit a broad range of biological and pharmacological properties. Among this group of alkaloids, sanguinarine, nitidine, fagaronine, and chelerythrine have the potential to form molecular complexes with DNA structures and have attracted recent attention for their possible clinical and pharmacological utility. This review focuses on the interaction of these alkaloids with polymorphic DNA structures (B-form, Z-form, HL-form, and triple helical form) reported by several research groups employing various physical techniques such as spectrophotometry, spectrofluorimetry, circular dichroism, NMR spectroscopy, thermal melting, viscometry as well as thermodynamic analysis by isothermal titration calorimetry and differential scanning calorimetry to elucidate the mode and mechanism of action at the molecular level to determine the structure-activity relationship. DNA binding properties of these alkaloids are interpreted in relation to their biological activity.

Abstract
In the context of the design and synthesis of minor groove binding and intercalating DNA ligands some new oligopyrrole carboxamides were synthesized. These hybrid molecules (combilexins) possess a variable and conformatively flexible spacer at the N-terminal end. As intercalating tricyclic systems acridone, acridine, anthraquinones and in a special case iminostilbene terminate the N-terminal end of the pyrrole chain. The cytotoxicity was examined by the NCI antitumor screening, furthermore, biophysical as well as biochemical studies were performed in order to get some information about the DNA binding properties and topoisomerase inhibition effect of this new series of molecules.

Abstract
A comparative study on the intercalating binding of sanguinarine, chelerythrine, and nitidine with CT DNA, poly(dG-dC).poly(dG-dC), poly(dA-dT).poly(dA-dT), and seven sequence-designed double-stranded oligodeoxynucleotides has been performed using fluorometric and spectrophotometric techniques, aiming at providing insights into their sequence selectivity for DNA-binding. The results show that both sanguinarine and nitidine bind preferentially to DNA containing alternating GC base pairs [d(TGCGCA)(2)], while chelerythrine exhibits quite distinct sequence selectivity from sanguinarine, which shows a high specificity for DNA containing contiguous GC base pairs [5'-TGGGGA-3'/3'-ACCCCT-5'].

Abstract
The development of resistance by Plasmodium falciparum to conventional drugs poses a threat to malaria control. There is therefore a need to find new, effective, and affordable remedies for malaria, including those derived from plants. This study demonstrates that crude, reverse-phase high-pressure liquid chromatography (RP-HPLC)-semipurified, and RP-HPLC-purified root extracts of Fagara zanthoxyloides inhibit the growth of P. falciparum in vitro, with 50% inhibitory concentrations (IC(50)s) of 4.90, 1.00, and 0.13 microg/ml, respectively. Roots of F. zanthoxyloides, known as chewing sticks, are widely used for tooth cleaning in West Africa. Microscopic examination of Giemsa-stained slides showed a virtual absence of schizonts in ring-stage synchronized cultures treated with crude extracts at concentrations of 30 to 60 microg/ml during 36 to 48 h of incubation. These observations suggest that the active constituent in the extract may be cytotoxic for P. falciparum trophozoites, thereby inhibiting their development to the schizont stage. A pure bioreactive fraction was subsequently obtained from the chromatographic separations. When this fraction was mixed with pure fagaronine, the mixture coeluted as a single peak on the analytical RP-HPLC column, suggesting that fagaronine may be the active antimalarial constituent of Fagara root extracts. Additional experiments showed that fagaronine also inhibited P. falciparum growth, with an IC(50) of 0.018 microg/ml. The results of this study suggest that the antimalarial activity of fagaronine deserves further investigation.

Abstract
Luotonin A is a cytotoxic alkaloid that has been shown to inhibit topoisomerase I via stabilization of the binary complex topoisomerase-DNA in the same fashion as camptothecin. The synthesis and the cytotoxic activity on the lung carcinoma cell line H460 of a series of derivatives of Luotonin A is reported. The compounds inhibit topoisomerase I but show weak cytotoxic activity, thus confirming the peculiarity of ring E of camptothecin for antitumor activity.
