Abstract
Due to the high conversion properties, azide compounds are widely utilized in organic synthesis. For instance, azide compounds readily release nitrogen to form a new N-C bond when they function as radical acceptors for the active intermediates in the reaction. Over the past decade, strategies employing azides as radical acceptors to construct nitrogen heterocycles have been extensively developed. This approach has emerged as a crucial method for synthesizing nitrogen heterocycles. Therefore, this paper provides a review of the research advancements in tandem cyclization reactions using azides as radical acceptors, summarizing the process of reaction design, exploration, reasoning of the mechanism, and prospects for further research of these reactions.

Abstract
Camptothecin and its analogues show important antitumor activity and have been used in clinical studies. However, hydrolysis of lactone in the E ring seriously attenuates the antitumor activity. To change this situation, aromathecin alkaloids are investigated in order to replace camptothecins. Potential antitumor activity has obtained more and more attention from organic and pharmaceutical chemists. As a member of the aromathecin alkaloids, rosettacin has been synthesized via different methods. This review summarizes recent advances in the synthesis of rosettacin.

Abstract
Camptothecin-like compounds are actively employed as anticancer drugs in clinical treatments. The aromathecin family of compounds, which contains the same indazolidine core structure as the camptothecin family of compounds, is also expected to display promising anticancer activity. Therefore, the development of a suitable and scalable synthetic method of aromathecin synthesis is of great research interest. In this study, we report the development of a new synthetic approach for constructing the pentacyclic scaffold of the aromathecin family by forming the indolizidine moiety after synthesizing the isoquinolone moiety. Thermal cyclization of 2-alkynylbenzaldehyde oxime to the isoquinoline N-oxide, followed by a Reissert-Henze-type reaction, forms the key strategy in this isoquinolone synthesis. Under the optimum reaction conditions for the Reissert-Henze-type reaction step, microwave irradiation-assisted heating of the purified N-oxide in acetic anhydride at 50 °C reduced the formation of the 4-acetoxyisoquinoline byproduct to deliver the desired isoquinolone at a 73% yield after just 3.5 h. The eight-step sequence employed afforded rosettacin (simplest member of the aromathecin family) at a 23.8% overall yield. The synthesis of rosettacin analogs was achieved by applying the developed strategy and may be generally applicable to the production of other fused indolizidine compounds.

Abstract
DNA topoisomerases are a group of enzymes omnipresent in all organisms. They maintain the DNA topology during replication, repair, recombination, and transcription. However, the structure of topoisomerase in protozoan parasites differs significantly from that of human topoisomerases; thus, this enzyme acts as a crucial target in drug development against parasitic diseases. Although the therapeutic potential of drugs targeting the parasitic topoisomerase is well known, to manage the shortcomings of currently available therapeutics and the emergence of drug resistance, the discovery of novel antiparasitic molecules is an urgent need. In this review, we describe various investigational and repurposed topoisomerase inhibitors developed against protozoan parasites over the past few years. Teaser: Fatal parasitic diseases are an increasing cause for concern; here, we provide a compilation of different inhibitors targeting DNA topoisomerases, enzymes that are essential for, and unique to, protozoan parasites; therefore, inhibitors are efficient and have few adverse effects.

Abstract
Reaction rate acceleration using green methods is an intriguing area of research for chemists. In this regard, water as a "green solvent" plays a crucial role in the acceleration of some organic transformations and reveals exclusive selectivity and reactivity in comparison with conventional organic solvents. In particular, multicomponent reactions (MCRs) as sustainable tools lead to the rapid generation of small-molecule libraries in water and aqueous media due to the prominent role of the hydrophobic effect. MCRs, as diversity-oriented synthesis (DOS) methods, have great efficiency with simple operations, atom, pot, and step economy synthesis, and mechanistic beauty. Among diverse classes of MCRs, isocyanide-based multicomponent reactions (I-MCRs), as sustainable and versatile reactions, have gained considerable attention in the synthesis of diverse heterocycle rings, especially in drug design because of the peculiar nature of isocyanide as a particular active reactant. I-MCRs that are performed in water are mild, environmentally friendly, and easily controlled, and have a reduced number of workup, purification, and extraction steps, which fit well with the advantages of "green" chemistry. Performing these powerful organic transformations in water and aqueous media is accompanied by acceleration owing to negative activation volumes, which originate from connecting several reactants together to generate a single product. It should be noted that the combination of MCR strategy and aqueous phase reaction is of growing interest for the development of sustainable synthetic techniques in organic conversions. However, an exclusive account focusing on the recent progress in eco-friendly I-MCRs for the construction of heterocycles in water and aqueous media is particularly lacking. This review highlights the progress of various kinds of I-MCRs in water and aqueous media as benign methods for the efficient construction of vital heterocyclic scaffolds, with a critical discussion of the subject in the period 2000-2021. We hope that this themed collection will be of interest and beneficial for organic and pharmaceutical chemists and will inspire more reaction development in this fascinating field.

Abstract
Thirty-eight new 3-arylaminoquinoxaline-2-carboxamide derivatives were in silico designed, synthesized and their cytotoxicity against five human cancer cell lines and one normal cells WI-38 were evaluated. Molecular mechanism studies indicated that N-(3-Aminopropyl)-3-(4-chlorophenyl) amino-quinoxaline-2-carboxamide (6be), the compound with the most potent anti-proliferation can inhibit the PI3K-Akt-mTOR pathway via down regulating the levels of PI3K, Akt, p-Akt, p-mTOR and simultaneously inhibit the phosphorylation of Thr308 and Ser473 residues in Akt kinase to servers as a dual inhibitor. Further investigation revealed that 6be activate the P53 signal pathway, modulated the downstream target gene of Akt kinase such p21, p27, Bax and Bcl-2, caused the fluctuation of intracellular ROS, Ca2+ and mitochondrial membrane potential to induce cell cycle arrest and apoptosis in MGC-803 cells. 6be also display moderate anti-tumor activity in vivo while displaying no obvious adverse signs during the drug administration. The results suggest that 3-arylaminoquinoxaline-2-carboxamide derivatives might server as new scaffold for development of PI3K-Akt-mTOR inhibitor.

Abstract
The advent of multicomponent reactions in the synthesis of heterocycles and their ever burgeoning applications in drug development, materials chemistry, and catalysis, have attracted a great deal of current scientific interest. In particular, the metal-free multicomponent synthesis of six membered N-heterocycles has undergone intensive research over the last two decades offering an environmentally benevolent means contrary to traditional metal catalysed reactions. To the best of our knowledge, there exists no exclusive review on the metal-free multicomponent synthesis of six membered N-heterocyles, and hence the present report highlights the progress on metal-free multicomponent reactions with their advantages and mechanistic insights to access monocyclic six-membered N-heterocycles including pyridine, pyrimidine, pyrazine, triazine and their hydrogenated derivatives. The literature is covered since 2000, and the contents offer not only striking methods for divergent synthesis of six-membered N-heterocycles but also put forward some new insights into the exploration of metal-free multicomponent chemistry.

Pyridazino[1,6-b]quinazolinones as new anticancer scaffold: Synthesis, DNA intercalation, topoisomerase I inhibition and antitumor evaluation in vitro and in vivo. Bioorg Chem 2020; 99:103814. [PMID: 32278208 DOI: 10.1016/j.bioorg.2020.103814] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2019] [Revised: 02/26/2020] [Accepted: 03/31/2020] [Indexed: 12/21/2022]
Abstract
A new anticancer N-containing heterocyclic scaffold was designed and 30 pyridazino[1,6-b]quinazolinone derivatives were synthesized and characterized. Antiproliferation evaluation in vitro against four human cancer cell lines including SK-OV-3(ovarian cell), CNE-2(nasopharyngeal cell), MGC-803(gastric cell) and NCI-H460(lung cell) indicated that most of them exhibited potent anticancer activity and the IC50 value of the most potent compound lowered to sub-μM. DNA interaction assay indicated that compounds 4e, 4g, 6o, 6p, 8o can intercalate into DNA. Compounds 6 and 8 also demonstrated potent topoisomerase I (topo I) activity. Annexin V- FITC/propidium iodide dual staining assay and cell cycle analysis indicated that 2-(4-bromophenyl)-4-((3-(diethylamino)propyl)amino) -10H-pyridazino [1,6-b]quinazolin- 10-one (8p) could induce arrest cell cycle at G2 phase and apoptosis in MGC-803 cells in a dose-dependent manner. The in vivo antitumor efficiency of compound 8p was also evaluated on MGC-803 xenograft nude mice, and the relative tumor growth inhibition was up to 55.9% at a dose of 20 mg/kg per two days. The results suggested that pyridazino[1,6-b]-quinazolinones might serve as a promising novel scaffold for the development of new antitumor agents.

Abstract
Background Canine leishmaniasis is a zoonotic disease caused by Leishmania infantum, being the dogs one of the major reservoirs of human visceral leishmaniasis. DNA topology is a consolidated target for drug discovery. In this regard, topoisomerase IB – one of the enzymes controlling DNA topology – has been poisoned by hundreds of compounds that increase DNA fragility and cell death. Aromathecins are novel molecules with a multiheterocyclic ring scaffold that have higher stability than camptothecins. Results Aromathecins showed strong activity against both forms of L. infantum parasites, free-living promastigotes and intra-macrophagic amastigotes harbored in ex vivo splenic explant cultures obtained from infected BALB/c mice. However, they prevented the relaxation activity of leishmanial topoisomerase IB weakly, which suggests that the inhibition of topoisomerase IB partially explains the antileishmanial effect of these compounds. The effect of aromathecins was also studied against a strain resistant to camptothecin, and results suggested that the trafficking of these compounds is not through the ABCG6 transporter. Conclusions Aromathecins are promising novel compounds against canine leishmaniasis that can circumvent potential resistances based on drug efflux pumps.

Abstract
Topoisomerases are DNA processing enzymes that relieve supercoiling (torsional strain) in DNA, are necessary for normal cellular division, and act by nicking (and then religating) DNA strands. Type 1B topoisomerase (Top1) is overexpressed in certain tumors, and the enzyme has been extensively investigated as a target for cancer chemotherapy. Various chemical agents can act as "poisons" of the enzyme's religation step, leading to Top1-DNA lesions, DNA breakage, and eventual cellular death. In this review, agents that poison Top1 (and have thus been investigated for their anticancer properties) are surveyed, including natural products (such as camptothecins and indolocarbazoles), semisynthetic camptothecin and luotonin derivatives, and synthetic compounds (such as benzonaphthyridines, aromathecins, and indenoisoquinolines), as well as targeted therapies and conjugates. Top1 has also been investigated as a therapeutic target in certain viral and parasitic infections, as well as autoimmune, inflammatory, and neurological disorders, and a summary of literature describing alternative indications is also provided. This review should provide both a reference for the medicinal chemist and potentially offer clues to aid in the development of new Top1 poisons.

Abstract
African sleeping sickness is responsible for thousands of deaths annually, and new therapeutics are needed. This study evaluated aromathecins, experimental inhibitors of mammalian topoisomerase IB, against Trypanosoma brucei African trypanosomes. The compounds had selectively toxic antiparasitic potency, in situ poisoning activity against the phylogenetically unique topoisomerase in these parasites, and a representative compound intercalated into DNA with micromolar affinity. DNA intercalation and topoisomerase poisoning may contribute to the antitrypanosomal activity of aromathecins.

Abstract
Protein arginine deiminase 4 (PAD4) is a calcium-dependent enzyme that catalyzes the conversion of arginine to citrulline within target proteins. Dysregulation of PAD4 has been implicated in a number of human diseases, including rheumatoid arthritis and other inflammatory diseases as well as cancer. In this study, we report on the design, synthesis, and evaluation of a new class of haloacetamidine-based compounds as potential PAD4 inhibitors. Specifically, we describe the identification of 4,5,6-trichloroindazole 24 as a highly potent PAD4 inhibitor that displays >10-fold selectivity for PAD4 over PAD3 and >50-fold over PAD1 and PAD2. The efficacy of this compound in cells was determined by measuring the inhibition of PAD4-mediated H4 citrullination in HL-60 granulocytes.

Abstract
A novel and practical procedure for the preparation of isoindolo[2,1- b]isoquinoline-7-carboxylate derivatives through a Rh(III)-catalyzed oxidative [4 + 1] cycloaddition of isoquinolones with diazoketoesters followed by an in situ deacylation reaction is disclosed. Intriguingly, the title compounds could be easily converted into isoindolo[2,1- b]isoquinolin-5(7 H)-ones via de-esterification, which are rosettacin analogues and frequently found in various natural alkaloids and synthetic drug molecules.

Abstract
An efficient Ru(ii)-catalyzed site-selective C-H arylation of 2-pyridones and 1-isoquinolinones was achieved with boronic acids by using pyridine as a directing group. The developed protocol is general and provides rapid access to an array of C6-arylated 2-pyridones and C3-arylated 1-isoquinolinones in excellent yields. These designed arylated 2-pyridones and 1-isoquinolinones can serve as key structural motifs for accessing functionalized pyridines and isoquinolines.

Abstract
A divergent synthesis of fused-quinolines has been explored by performing Ugi four-component condensation and sulfuric acid promoted deprotection/Povarov-type reaction in one-pot. The process involves Ugi condensation of propiolic acids, aldehydes/ketones, aminoaldehyde acetals and isocyanides followed by sulfuric acid promoted deprotection and Povarov-type reaction with anilines in ethanol. This method enables straightforward access to the structurally diverse 2,3-dihydro-1H-pyrrolo[3,4-b]quinolin-1-ones (DHPQ), 3,4-dihydrobenzo[b][1,6]naphthyridin-1(2H)-ones (DHBN), and 2,3,4,5-tetrahydro-1H-azepino[4,3-b]quinolin-1-ones (THAQ), starting from readily available starting materials.

Abstract
The synthesis of various substituted triazole-indenoisoquinoline hybrids was performed based on a CuI-catalyzed 1,3-cycloaddition between propargyl-substituted derivatives and the azide-containing indenoisoquinoline. Besides, a variety of N-(alkyl)propargylindenoisoquinolines was used as substrates for the construction of triazole-indenoisoquinoline-AZT conjugated via a click chemistry-mediated coupling with 3'-azido-3'-deoxythymidine (AZT). Thus, twenty three new indenoisoquinoline-substituted triazole hybrids were successfully prepared and evaluated as cytotoxic agents, revealing an interesting anticancer activity of four triazole linker-indenoisoquinoline-AZT hybrids in KB and HepG2 cancer cell lines.

Abstract
Tilorone dihydrochloride (1) has great potential for inducing interferon against pathogenic infection. In this paper, we describe a convenient preparation method for 2,7-dihydroxyfluoren-9-one (2), which is a usual pharmaceutical intermediate for preparing tilorone dihydrochloride (1). In the novel method, methyl esterification of 4,4′-dihydroxy-[1,1′-biphenyl]-2-carboxylic acid (4) was carried out under milder conditions with higher yield and played an important role in the preparation of compound 2. The structures of the relative intermediates and target compound were characterized by melting point, IR, MS, and 1H-NMR. Furthermore, the synthesized tilorone dihydrochloride exhibited an obvious effect on induction of interferon-α (IFN-α) in mice within 12 h, and the peak level was observed until 24 h. This fruitful work has resulted in tilorone dihydrochloride becoming available in large-scale and wide application in clinics, which has a good pharmaceutical development prospects.

Abstract
To investigate the cytotoxic effects of β-carboline alkaloids on human gastric cancer SGC-7901 cells. Human gastric cancer SGC-790s1 cells were treated with β-carboline alkaloids at the concentration of 0, 10, 20, 30 and 40 μg/ml for 48 hr. Cell viability was measured by Cell Counting Kit-8 assay. Cell apoptosis was detected by Hoechst 33258 staining and DNA fragmentation analysis. The expression of phosphatase and tensin homolog (PTEN) and extracellular signal-regulated kinase (ERK) was examined by quantitative real-time PCR (qRT-PCR) assay and western blot analysis. β-carboline alkaloids inhibited the growth of SGC-7901 cells concentration dependently. β-carboline alkaloids treated SGC-7901 cells displayed apoptotic nuclei as detected using Hoechst 33258 staining. β-carboline alkaloids also induced DNA ladder, indicative of apoptosis in SGC-7901 cells concentration-dependently. Furthermore, β-carboline alkaloids increased PTEN and decreased ERK mRNA expression in SGC-7901 cells in a concentration dependent manner. They also increased PTEN and decreased ERK protein expression. β-carboline alkaloids inhibit the growth and induce apoptosis of SGC-7901 cells. The cytotoxic effects of β-carboline alkaloids might correlate with increased PTEN expression and decreased ERK expression in SGC-7901 cells.

Abstract
Intramolecular cyclization of the heteroenyne-allene, 2-((phenylimino)methyleneamino)-benzonitrile (1) in the presence of HCl to produce 2-chloro-3-phenyl-4(3H)-quinazoliniminium chloride (Qz) involves the formation of two new bonds: a C-Cl bond and a C-N bond. We propose five pathways for this reaction. Four of these pathways involve chloride capture to form the C-Cl bond prior to the intramolecular nucleophilic attack to form the C-N bond, while one pathway involves ring closure to form the C-N bond prior to C-Cl bond formation. All calculations were carried out at B3LYP and MP2 levels of theory and employed the 6-311G* basis set. The solvent effects were considered using a Polarized Continuum Model with dichloromethane as the solvent. The calculations at both levels show that the mechanism involves initial protonation of 1, preferentially at Nα to give 2 which rapidly captures the chloride ion to form 5. This intermediate is protonated at the -CN group to form 8ROT, which then tautomerizes to its more stable isomer 9ROT. The latter undergoes intramolecular nucleophilic attack from Nβ to the protonated -CN group to form the cyclized intermediate 12, which tautomerizes to its most stable isomer 13. The coordination of Cl(-) ion present in the solution with 13 gives the final product Qz.

Abstract
The continued interest in designing novel topoisomerase I (Topo I) inhibitors and the lack of adequate ligand-based computer-aided drug discovery efforts combined with the drawbacks of structure-based design prompted us to explore the possibility of developing ligand-based three-dimensional (3D) pharmacophore(s). This approach avoids the pitfalls of structure-based techniques because it only focuses on common features among known ligands; furthermore, the pharmacophore model can be used as 3D search queries to discover new Topo I inhibitory scaffolds. In this article, we employed the HipHop module using Discovery Studio to construct plausible binding hypotheses for clinically used Topo I inhibitors, such as camptothecin, topotecan, belotecan, and SN-38, which is an active metabolite of irinotecan. The docked pose of topotecan was selected as a reference compound. The first hypothesis (Hypo 01) among the obtained 10 hypotheses was chosen for further analysis. Hypo 01 had six features, which were two hydrogen-bond acceptors, one hydrogen-bond donor, one hydrophob aromatic and one hydrophob aliphatic, and one ring aromatic. Our obtained hypothesis was checked by using some of the aromathecin derivatives which were published for their Topo I inhibitory potency. Moreover, five structures were found to be possible anti-Topo I compounds from the DruglikeDiverse database. From this research, it can be suggested that our model could be useful for further studies in order to design new potent Topo I-targeting antitumor drugs.

Abstract
3-Nitroindenoisoquinoline human topoisomerase IB (Top1) poisons have potent antiproliferative effects on cancer cells. The undesirable nitro toxicophore could hypothetically be replaced by other functional groups that would retain the desired biological activities and minimize potential safety risks. Eleven series of indenoisoquinolines bearing 3-nitro bioisosteres were synthesized. The molecules were evaluated in the Top1-mediated DNA cleavage assay and in the National Cancer Institute's 60 cell line cytotoxicity assay. The data reveal that fluorine and chlorine may substitute for the 3-nitro group with minimal loss of Top1 poisoning activity. The new information gained from these efforts can be used to design novel indenoisoquinolines with improved safety.

Abstract
PURPOSE Development and evaluation of camptothecin-loaded-microemulsion (ME) and -magnetic microemulsion (MME) for passive/active-targeted delivery to BALB/c mice-bearing breast cancer. METHODS Based on the pseudo-ternary phase diagrams camptothecin-loaded-MEs and -MMEs were developed using benzyl alcohol:Captex 300 (3:1), TPGS:Tween 80 (2:1) and water. Furthermore, characterized for their droplet size distribution, magnetic susceptibility and effect of droplet size in plasma and evaluated for in vitro and in vivo targeting potential, drug release, haemolytic potential, cytotoxicity, genotoxicity, in vivo biodistribution and lactone ring stability. RESULTS Drug-loaded MEs showed uniform droplet distribution, extended drug release (76.07 ± 4.30% at 24 h), acceptable level of haemolytic activity (<20%), significant cytotoxicity (129 ± 3.9 ng/mL) against MCF-7 cancer cells and low DNA damage in lymphocytes. Targeting potential of MMEs was documented in 4T1 breast cancer-induced BALB/c mice. MMEs were concentrated more at the target tissue on introduction of external magnetic field. In vivo biodistribution study documented the active targeting of 5067.56 ± 354.72 ng/gm and passive targeting of 1677.58 ± 134.20 ng/gm camptothecin to breast cancer from MME and ME, respectively. Lactone stability study shows around 80% of the lactone stable at 24 h. CONCLUSIONS Developed ME and MME may act as a promising nanocarrier for efficient targeting of breast cancer tissues.

Abstract
![]()
Topoisomerase
IB (Top1) is a key eukaryotic nuclear enzyme that
regulates the topology of DNA during replication and gene transcription.
Anticancer drugs that block Top1 are either well-characterized interfacial
poisons or lesser-known catalytic inhibitor compounds. Here we describe
a new class of cytotoxic redox-stable cationic Au3+ macrocycles
which, through hierarchical cluster analysis of cytotoxicity data
for the lead compound, 3, were identified as either poisons
or inhibitors of Top1. Two pivotal enzyme inhibition assays prove
that the compounds are true catalytic inhibitors of Top1. Inhibition
of human topoisomerase IIα (Top2α) by 3 was
2 orders of magnitude weaker than its inhibition of Top1, confirming
that 3 is a type I-specific catalytic inhibitor. Importantly,
Au3+ is essential for both DNA intercalation and enzyme
inhibition. Macromolecular simulations show that 3 intercalates
directly at the 5′-TA-3′ dinucleotide sequence targeted
by Top1 via crucial electrostatic interactions, which include π–π
stacking and an Au···O contact involving a thymine
carbonyl group, resolving the ambiguity of conventional (drug binds
protein) vs unconventional (drug binds substrate) catalytic inhibition
of the enzyme. Surface plasmon resonance studies confirm the molecular
mechanism of action elucidated by the simulations.

Abstract
The DNA-relaxing enzyme topoisomerase I (Top1) can be inhibited by heterocyclic compounds such as indolocarbazoles and indenoisoquinolines. Carbohydrate and hydroxyl-containing side chains are essential for the biological activity of indolocarbazoles. The current study investigated how similar functionalities could be "translated" to the indenoisoquinoline system and how stereochemistry and hydrogen bonding affect biological activity. Herein is described the preparation and assay of indenoisoquinolines substituted with short-chain alcohols, diols, and carbohydrates. Several compounds (including those derived from sugars) display potent Top1 poisoning and antiproliferative activities. The Top1 poisoning activity of diol-substituted indenoisoquinolines is dependent upon stereochemistry. Although the effect is striking, molecular modeling and docking studies do not indicate any reason for the difference in activity due to similar calculated interactions between the ligand and Top1-DNA complex and ambiguity about the binding mode. A stereochemical dependence was also observed for carbohydrate-derived indenoisoquinolines. Although similar trends were observed in other classes of Top1 inhibitors, the exact nature of this effect has yet to be elucidated.
