Abstract
BACKGROUND Chelerythrine is an important alkaloid used in agriculture and medicine. However, its structural complexity and low abundance in nature hampers either bulk chemical synthesis or extraction from plants. Here, we reconstructed and optimized the complete biosynthesis pathway for chelerythrine from (S)-reticuline in Saccharomyces cerevisiae using genetic reprogramming. RESULTS The first-generation strain Z4 capable of producing chelerythrine was obtained via heterologous expression of seven plant-derived enzymes (McoBBE, TfSMT, AmTDC, EcTNMT, PsMSH, EcP6H, and PsCPR) in S. cerevisiae W303-1 A. When this strain was cultured in the synthetic complete (SC) medium supplemented with 100 µM of (S)-reticuline for 10 days, it produced up to 0.34 µg/L chelerythrine. Furthermore, efficient metabolic engineering was performed by integrating multiple-copy rate-limiting genes (TfSMT, AmTDC, EcTNMT, PsMSH, EcP6H, PsCPR, INO2, and AtATR1), tailoring the heme and NADPH engineering, and engineering product trafficking by heterologous expression of MtABCG10 to enhance the metabolic flux of chelerythrine biosynthesis, leading to a nearly 900-fold increase in chelerythrine production. Combined with the cultivation process, chelerythrine was obtained at a titer of 12.61 mg per liter in a 0.5 L bioreactor, which is over 37,000-fold higher than that of the first-generation recombinant strain. CONCLUSIONS This is the first heterologous reconstruction of the plant-derived pathway to produce chelerythrine in a yeast cell factory. Applying a combinatorial engineering strategy has significantly improved the chelerythrine yield in yeast and is a promising approach for synthesizing functional products using a microbial cell factory. This achievement underscores the potential of metabolic engineering and synthetic biology in revolutionizing natural product biosynthesis.

Abstract
An efficient ruthenium(II)-catalyzed tandem C-C/C-N bond formation with aryl amides and 7-azabenzonorbornadienes has been developed to synthesize cis-fused dihydrobenzo[c]phenanthridinones. The amide group functions as a directing group as well as a leaving group and provides an easy access to the pharmaceutically useful benzo[c]phenanthridine alkaloids such as nitidine and fagaronine analogues. The present methodology is compatible with various functional groups with respect to azabicyclic alkenes and aromatic amides. The reaction mechanism involving directing-group-assisted C-H activation was proposed and supported by the deuterium labeling studies.

Abstract
Tyrosyl-DNA phosphodiesterase 1 (TDP1) is an enzyme that repairs DNA lesions caused by the trapping of DNA topoisomerase IB (TOP1)-DNA break-associated crosslinks. TDP1 inhibitors have synergistic effect with TOP1 inhibitors in cancer cells and can overcome cancer cell resistance to TOP1 inhibitors. Here, we report the synthesis of 11-aminoalkoxy substituted benzophenanthridine derivatives as selective TDP1 inhibitors and show that six compounds 14, 16, 18, 20, 25 and 27 exhibit high TDP1 inhibition potency. The most potent TDP1 inhibitor 14 (IC50 = 1.7 ± 0.24 μM) induces cellular TDP1cc formation and shows synergistic effect with topotecan in four human cancer cell lines MCF-7, A549, H460 and HepG2.

Abstract
A modularly convergent and divergent strategy was established for the family synthesis of both protoberberine and protonitidine alkaloids. The robust, scalable, and flexible synthetic route featured a collective preparation of protoberberine and protonitidine alkaloids from a common isoquinoline assembled from pyridyne as the key synthon, which was based on the selective N-C or C-C cyclization via distinct processes. Through the strategy, 20 protoberberine alkaloids, 5 protonitidine alkaloids, and 11 analogues with diverse substituents were comprehensively aquired.

Abstract
In a screening of an extract library from plants used in Traditional Chinese Medicine the MeOH extract of Toddalia asiatica inhibited proliferation of human primary T cells with an IC50 of 25.8 μg/mL. Activity in the extract was tracked by HPLC activity profiling, and a total of 15 compounds were characterized. Three compounds, toddalic acid (6) and both enantiomers (7a and 7b) of toddanolic acid (7), were new natural products, and two recently published compounds, (2'R)-toddalolactone 3'-O-β-d-glucopyranoside (10) and (2'S)-toddalolactone 2'-O-β-d-glucopyranoside (11), were described in detail for the first time. The absolute configurations of compounds 8, 9, 10, 12, 13, and 15 were determined by comparison of experimental and calculated ECD spectra. For glucosides 9 and 10, ECD data and chiral-phase HPLC of the aglycones after enzymatic hydrolysis confirmed the results. Nitidine chloride (4) inhibited proliferation of primary human T cells with an IC50 of 0.4 μM.

Abstract
In spite of their various pharmacological properties the anti-inflammatory potential of benzo[c]phenanthridines remained underexplored. Thus, for the first time PDE4 inhibitory potential of 11,12-dihydro benzo[c]phenanthridine/benzo[c]phenanthridine was assessed in vitro. Elegant synthesis of these compounds was performed via a multi-step sequence consisting of a Pd-catalyzed unusual construction of 4-allyl isocoumarin ring and FeCl3-mediated intramolecular regio- as well as site-selective arene-allyl cyclization as key steps. The overall strategy involved Sonogashira coupling followed by isocoumarin and isoquinolone synthesis, then chlorination and subsequent cyclization to afford a range of 11,12-dihydro derivatives. One of these dihydro compounds was converted to the corresponding benzo[c]phenanthridine that showed concentration dependent inhibition of PDE4B affording an initial hit molecule. The SAR study suggested that 11,12-dihydro analogs were less potent than the compound having unsaturation at the same part of the ring.

Abstract
Multifactorial neurodegenerative disorders such as Alzheimer's disease (AD) are considered a growing public health problem due the rising incidence and low effectiveness of current treatments [6]. Since pharmacotherapy based on a single target has been insufficient for drug development in complex diseases, the emerging multi-target approach is a promising strategy for the search of new anti-AD drug candidates. Herein described natural isoquinoline alkaloids were investigated for multi-target activity on key mechanisms associated with the AD's pathogenesis, i.e. cholinergic depletion, beta amyloid (Aβ) aggregation and oxidative stress. Alkaloid isolation from root extract of Zanthoxylum rigidum was carried out using multi-step chromatography and TLC-bioautography against acetylcholinesterase (AChE) giving eight purified isoquinoline alkaloids. Isolated compounds were tested for inhibitory activity against cholinesterase (AChE and BChE), monoamine oxidase (MAO-A and B) and Aβ aggregation. Our study revealed two benzophenanthridine alkaloids, nitidine (5) and avicine (7), as the most potent multi-target candidates. Both showed dual cholinesterase inhibition, being more active against AChE over BChE, with IC50 values in sub-micromolar range in AChE. Kinetic analysis with cholinesterase showed, that both compounds are reversible-mixed inhibitors, where avicine (7) presented highest potency with Ki values of 0.063 µM (EeAChE), 0.511 µM (HrAChE) and 0.123 µM (EqBChE). In addition, these alkaloids presented moderate Aβ1-42 anti-aggregation activity and MAO-A inhibition with IC50 values between 0.5 and 2 µM. Our findings suggest that avicine (7) is a promising natural compound and multifunctional candidate representing a suitable starting point for the development of new therapeutic agents for Alzheimer's disease.

Abstract
A facile and diversity-oriented synthetic strategy toward aminocyclitol natural products from inexpensive C2-symmetric l-tartaric acid was developed. The pivotal epoxide was used as a common intermediate to accomplish eight diverse target molecules in six to eleven steps. Various allyl-amine-type conduramines were synthesized in a diastereoselective manner. Heck arylation was explored to construct a phenanthridone ring in a concise synthesis of (+)-lycoricidine. In addition, a highly efficient formal synthesis of (-)-laminitol was developed.

Abstract
A Pd-catalyzed synthesis of 3,4,5-trisubstituted cyclopentenes from diazabicyclic olefins and o-iodobenzoates has been developed. The hitherto unknown cascade process involves three stages: carbopalladation, oxypalladation and a Tsuji-Trost reaction. We have also developed a facile route involving a novel benzylic C-H activation towards cyclopentenoindane moieties.

Abstract
A new type of three-component reaction of air-stable isochromenylium tetrafluoroborates with electron-rich stilbenes in acetonitrile has been developed under catalyst-free conditions in this work. This cascade multibond-formation reaction is initiated by an intermolecular oxa [4 + 2]-cycloaddition, relayed with a nucleophilic addition of acetonitrile, and terminated by an intramolecular Friedel-Crafts reaction, affording the corresponding benzo[c]phenanthridine analogues in one step.

Abstract
A novel procedure for the Cu-catalyzed systematic synthesis of phenanthridinium bromide is reported. This transformation was achieved with direct construction of central pyridinium core by using an in situ formed biaryl imine as a substrate. Tolerance of a very wide variety of N-substituents is indicated; this has never previously been disclosed by other reports. Application of this method to synthesis of the natural alkaloid bicolorine, and its derivatives, was also carried out in only three synthetic steps from commercially available compounds.

Abstract
Diverse and controllable pathways induced by palladium-catalyzed intramolecular Heck reaction of N-vinylacetamides for the synthesis of nitrogen-containing products in reasonable to high yields via tuning the phosphine ligands and bases are reported. Domino reactions including unique β-N-Pd elimination, 1,4-Pd migration, or direct acyl C-H bond functionalization were found to be involved forming different products, respectively. Given the ability of using the same starting material to generate diverse products via completely different chemoselective processes, these current methodologies offer straightforward access to valuable nitrogen-containing products under mild reaction conditions as well as inspire the discovery of novel reactions.

Abstract
Allylic trichloroacetimidates bearing a 2-vinyl or 2-allylaryl group have been designed as substrates for a one-pot, two-step multi-bond-forming process leading to the general preparation of aminoindenes and amino-substituted 1,4-dihydronaphthalenes. The synthetic utility of the privileged structures formed from this one-pot process was demonstrated with the total synthesis of four oxybenzo[c]phenanthridine alkaloids, oxychelerythrine, oxysanguinarine, oxynitidine, and oxyavicine. An intramolecular biaryl Heck coupling reaction, catalyzed using the Hermann-Beller palladacycle was used to effect the key step during the synthesis of the natural products.

Abstract
A new benzo[c]phenanthridine, oxynorchelerythrine (1), and two new benzenoid derivatives, methyl 4-(2-hydroxy-4-methoxy-3-methyl-4-oxobutoxy)benzoate (2) and (E)-methyl 4-(4-((Z)-3-methoxy-3-oxoprop-1-enyl)phenoxy)-2-methylbut-2-enoate (3), have been isolated from the twigs of Zanthoxylum ailanthoides, together with 11 known compounds (4–14). The structures of these new compounds were determined through spectroscopic and MS analyses. Among the isolated compounds, decarine (4), (−)-syringaresinol (6), (+)-episesamin (8), glaberide I (9), (−)-dihydrocubebin (10), and xanthyletin (11) exhibited potent inhibition (IC50 values ≤ 4.79 μg/mL) of superoxide anion generation by human nutrophils in response to N-formyl-l-methionyl-l-leucyl-l-phenylalanine/cytochalasin B (fMLP/CB). Compounds 4, 8, and 11 also inhibited fMLP/CB-induced elastase release with IC50 values ≤ 5.48 μg/mL.

Abstract
Nitidine Chloride (NC) has been shown to have anti-cancer effects on various tumors. However, whether NC could exert anti-metastasis activity in renal cancer cells and the underlying mechanisms have not been elucidated. In this work, our data demonstrated the anti-metastasis effects of NC on renal cancer cells in vitro. With scratch assay and transwell assays, we found that NC potently suppressed the migration and invasion of 786-O and A498 cells. Mechanistically, we presented that NC significantly decreased phosphorylation of AKT, accompanied by down-regulation of MMP-2 and MMP-9. Furthermore, a specific AKT inhibitor, LY294002, could enhance the anti-metastasis effects of NC, which indicated that NC suppressed metastasis of renal cancer cells partly via inhibition of AKT activity. Taken together, our results imply that NC can be developed as a potential anti-metastasis agent to renal cancer.
