Abstract
G-quadruplexes are noncanonical four-stranded DNA secondary structures. MYC is a master oncogene and the G-quadruplex formed in the MYC promoter functions as a transcriptional silencer and can be stabilized by small molecules. We have previously revealed a novel mechanism of action for indenoisoquinoline anticancer drugs, dual-downregulation of MYC and inhibition of topoisomerase I. Herein, we report the design and synthesis of novel 7-aza-8,9-methylenedioxyindenoisoquinolines based on desirable substituents and π-π stacking interactions. These compounds stabilize the MYC promoter G-quadruplex, significantly lower MYC levels in cancer cells, and inhibit topoisomerase I. MYC targeting was demonstrated by differential activities in Raji vs CA-46 cells and cytotoxicity in MYC-dependent cell lines. Cytotoxicities in the NCI-60 panel of human cancer cell lines were investigated. Favorable pharmacokinetics were established, and in vivo anticancer activities were demonstrated in xenograft mouse models. Furthermore, favorable brain penetration, brain pharmacokinetics, and anticancer activity in an orthotopic glioblastoma mouse model were demonstrated.

Eur J Med Chem 2024; 265:116061. [PMID: 38154256 DOI: 10.1016/j.ejmech.2023.116061] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Revised: 11/27/2023] [Accepted: 12/14/2023] [Indexed: 12/30/2023]
Abstract
A series of β-carboline derivatives were designed and synthesized by introducing the chalcone moiety into the harmine. The synthesized derivatives were evaluated their anti-proliferative activities against six human cancer cell lines (MCF-7, MDA-MB-231, HepG2, HT29, A549, and PC-3) and one normal cell line (L02). Among them, compound G11 exhibited the potent anti-proliferative activity against MCF-7 cell line, with an IC50 value of 0.34 μM. Further biological studies revealed that compound G11 inhibited colony formation of MCF-7 cells, suppressed MCF-7 cell migration by downregulating migration-associated protein MMP-2. In addition, it could induce apoptosis of MCF-7 cells by downregulating Bcl-2 and upregulating Cleaved-PARP, Bax, and phosphorylated Bim proteins. Furthermore, compound G11 can act as a Topo I inhibitor, affecting DNA synthesis and transcription, thereby inhibiting cancer cell proliferation. Moreover, compound G11 inhibited tumor growth in 4T1 syngeneic transplant mice with an inhibition rate of 43.19 % at a dose of 10 mg/kg, and 63.87 % at 20 mg/kg, without causing significant toxicity to the mice or their organs, achieving the goal of reduced toxicity and increased efficacy. All these results indicate of G11 has enormous potential as an anti-tumor agent and merits further investigation.

Eur J Med Chem 2024; 265:116049.

Abstract
Camptothecin is a pentacyclic natural alkaloid that inhibits the hTop1 enzyme involved in DNA transcription and cancer cell growth. Camptothecin structure pitfalls prompted us to design new congeners using a structure simplification strategy to reduce the ring extension number from pentacyclic to tetracyclic while maintaining potential stacking of the new compounds with the DNA base pairs at the Top1-mediated cleavage complex and aqueous solubility, as well as minimizing compound-liver toxicity. The principal axis of this study was the verification of hTop1 inhibiting activity as a possible mechanism of action and the elaboration of new simplified inhibitors with improved pharmacodynamic and pharmacokinetic profiling using three structure panels (A-C) of (isoquinolinoimidazoquinazoline), (imidazoquinazoline), and (imidazoisoquinoline), respectively. DNA relaxation assay identified five compounds as hTop1 inhibitors belonging to the imidazoisoquinolines 3a,b, the imidazoquinazolines 12, and the isoquinolinoimidazoquinazolines 7a,b. In an MTT cytotoxicity assay against different cancer cell lines, compound 12 was the most potent against HOS bone cancer cells (IC50 = 1.47 μM). At the same time, the other inhibitors had no detectable activity against any cancer cell type. Compound (12) demonstrated great penetrating power in the HOS cancer cells' 3D-multicellular tumor spheroid model. Bioinformatics research of the hTop1 gene revealed that the TP53 cell proliferative gene is in the network of hTop1. The finding is confirmed empirically using the gene expression assay that proved the increase in p53 expression. The impact of structure simplification on compound 12 profile, characterized by the absence of acute oral liver toxicity when compared to Doxorubicin as a standard inhibitor, the lethal dose measured on Swiss Albino female mice and reported at LD50 = 250 mg/kg, and therapeutic significance in reducing colon adenocarcinoma tumor volume by 75.36 % after five weeks of treatment with compound 12. The molecular docking solutions of the active CPT-based derivative 12 and the inactive congener 14 into the active site of hTop1 and the activity cliffing of such MMP directed us to recommend the addition of HBD and HBA variables to compound 12 imidazoquinazoline core scaffold to enhance the potency via hydrogen bond formation with the major groove amino acids (Asp533, Lys532) as well as maintaining the hydrogen bond with the minor groove amino acid Arg364.

Dual Targeting Topoisomerase/G-Quadruplex Agents in Cancer Therapy-An Overview. Biomedicines 2022; 10:biomedicines10112932.

Abstract
Topoisomerase (Topo) inhibitors have long been known as clinically effective drugs, while G-quadruplex (G4)-targeting compounds are emerging as a promising new strategy to target tumor cells and could support personalized treatment approaches in the near future. G-quadruplex (G4) is a secondary four-stranded DNA helical structure constituted of guanine-rich nucleic acids, and its stabilization impairs telomere replication, triggering the activation of several protein factors at telomere levels, including Topos. Thus, the pharmacological intervention through the simultaneous G4 stabilization and Topos inhibition offers a new opportunity to achieve greater antiproliferative activity and circumvent cellular insensitivity and resistance. In this line, dual ligands targeting both Topos and G4 emerge as innovative, efficient agents in cancer therapy. Although the research in this field is still limited, to date, some chemotypes have been identified, showing this dual activity and an interesting pharmacological profile. This paper reviews the available literature on dual Topo inhibitors/G4 stabilizing agents, with particular attention to the structure-activity relationship studies correlating the dual activity with the cytotoxic activity.

Abstract
Bromodomain-containing protein 4 (BRD4) is an emerging epigenetic drug target for intractable inflammatory disorders. The lack of highly selective inhibitors among BRD4 family members has stalled the collective understanding of this critical system and the progress toward clinical development of effective therapeutics. Here we report the discovery of a potent BRD4 bromodomain 1 (BD1)-selective inhibitor ZL0590 (52) targeting a unique, previously unreported binding site, while exhibiting significant anti-inflammatory activities in vitro and in vivo. The X-ray crystal structural analysis of ZL0590 in complex with human BRD4 BD1 and the associated mutagenesis study illustrate a first-in-class nonacetylated lysine (KAc) binding site located at the helix αB and αC interface that contains important BRD4 residues (e.g., Glu151) not commonly shared among other family members and is spatially distinct from the classic KAc recognition pocket. This new finding facilitates further elucidation of the complex biology underpinning bromodomain specificity among BRD4 and its protein-protein interaction partners.

Abstract
The discovery that certain indenoisoquinolines inhibit the religation reaction of DNA in the topoisomerase I-DNA-indenoisoquinoline ternary complex led to a structure-based drug design research program which resulted in three representatives that entered Phase I clinical trials in cancer patients at the National Cancer Institute. This has stimulated a great deal of interest in the design and execution of new synthetic pathways for indenoisoquinoline production. More recently, modulation of the substitution pattern and chemical nature of substituents on the indenoisoquinoline scaffold has resulted in a widening scope of additional biological targets, including RXR, PARP-1, MYC promoter G-quadruplex, topoisomerase II, estrogen receptor, VEGFR-2, HIF-1α, and tyrosyl DNA phosphodiesterases 1 and 2. Furthermore, convincing evidence has been advanced supporting the potential use of indenoisoquinolines for the treatment of diseases other than cancer. The rapidly expanding indenoisoquinoline knowledge base has provided a firm foundation for further advancements in indenoisoquinoline chemistry, pharmacology, and therapeutics.

Abstract
We have developed cobalt-catalyzed, bidentate 2-(1-methylhydrazinyl)pyridine (MHP)-directed C(sp2)-H alkylation/annulation of benzoic hydrazides with various alkenes. Notably, diverse cyclopenta[c]isoquinolinones and dihydroisoquinolinones were obtained via this functional group-tolerant protocol. The reaction can be performed on a gram scale while maintaining an excellent yield, and the directing group can be removed efficiently under mild conditions. Furthermore, density-functional theory (DFT) calculations provide an incisive understanding of the observed regioselectivities for different olefins.

Abstract
A concise copper catalysis strategy for the addition-cyclization of cyclic oxime esters across 1,6-enynes with high stereoselectivity to generate 1-indanones bearing an all-carbon quaternary center is reported. In this process, single-electron reduction of cyclic oxime esters enables deconstructive carbon-carbon cleavage to provide a key cyanopropyl radical poised for the addition-cyclization. This reaction is redox-neutral, exhibits good functional group compatibility, and features 100% atomic utilization. This process driven by copper catalyst makes readily available cyclic oxime esters as bifunctional reagents to demonstrate convergent synthesis.

A new copper/silver-co-mediated three-component bicyclization of benzene-linked 1,6-enynes with ICF2CO2Et with TMSN3 was reported, and used to produce a wide range of hitherto unreported difluorinated tetrahydroindeno[1,2-c]azepine-3,6-diones with moderate to good yields. The mechanistic pathway consists of radical-induced 1,6-addition-cyclization, oxidative addition, reductive elimination, nitrene insertion and N-O cleavage, resulting in continuous multiple bond-forming events including C-C and C-N bonds to build up a 6/5/7 tricyclic framework.

[PMID: 33142421 DOI: 10.1016/j.bioorg.2020.104266] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2020] [Revised: 08/14/2020] [Accepted: 08/31/2020] [Indexed: 02/06/2023]
Abstract
Replication proteins are sought as a potential targets for antimicrobial agents. Despite their promising target characteristics, only topoisomerase II inhibitors targeting DNA gyrase and/or topoisomerase IV have reached clinical use. Topoisomerases are the enzymes that are essential for cellular functions and various biological activities. A wide range of natural and synthetic compounds have been identified as potential topoisomerase inhibitors but the resistance is most commonly found in these drugs. The emergence of FQ resistance has increased the need for the development of novel topoisomerase inhibitors with efficacy and high potency against FQ-resistant strains. Besides structural modifications of existing FQ scaffolds, novel non-quinolone topoisomerase II inhibitors, known as novel bacterial topoisomerase inhibitors, have been developed which showed remarkable inhibitory activity against DNA gyrase/topoisomerase IV or both with an improved spectrum of antibacterial potency including drug-resistant strains. This review aims to summarize various recent advancements in the medicinal chemistry of topoisomerase inhibitors with the following objectives: (1) To represent inclusive data on types of topoisomerases and various marketed topoisomerase inhibitors as drugs; (2) To discuss the recent advances in the medicinal chemistry of various topoisomerase inhibitors (DNA gyrase and topo IV) belonging to different structural classes as potential antibacterial agents; (3) To summarizes the structure activity relationship (SAR) including in silico and mechanistic studies to afford ideas and to provide focused direction for the development of new chemical entities which are effective against drug-resistant bacterial pathogens and biofilms.

Abstract
Bromodomain-containing protein 4 (BRD4) represents a promising drug target for anti-inflammatory therapeutics. Herein, we report the design, synthesis, and pharmacological evaluation of novel chromone derivatives via scaffold hopping to discover a new class of orally bioavailable BRD4-selective inhibitors. Two potent BRD4 bromodomain 1 (BD1)-selective inhibitors 44 (ZL0513) and 45 (ZL0516) have been discovered with high binding affinity (IC50 values of 67-84 nM) and good selectivity over other BRD family proteins and distant BD-containing proteins. Both compounds significantly inhibited the expression of Toll-like receptor-induced inflammatory genes in vitro and airway inflammation in murine models. The cocrystal structure of 45 in complex with human BRD4 BD1 at a high resolution of 2.0 Å has been solved, offering a solid structural basis for its binding validation and further structure-based optimization. These BRD4 BD1 inhibitors demonstrated impressive in vivo efficacy and overall promising pharmacokinetic properties, indicating their therapeutic potential for the treatment of inflammatory diseases.

Abstract
DNA topoisomerases are considered consolidated druggable targets against diseases produced by trypanosomatids. Several reports indicated that indenoisoquinolines, a family of non-camptothecinic based topoisomerase poisons, have a strong leishmanicidal effect both in vitro and in vivo in murine models of visceral leishmaniasis. The antileishmanial effect of the indenoisoquinolines implies several mechanisms that include the stabilization of the cleavage complex, histone H2A phosphorylation and DNA fragmentation. A series of 20 compounds with the indenoisoquinoline scaffold and several substituents at positions N6, C3, C8 and C9, were tested both in promastigotes and in intramacrophage splenic amastigotes obtained from an experimental murine infection. The antileishmanial effect of most of these compounds was within the micromolar or submicromolar range. In addition, the introduction of an N atom in the indenoisoquinoline ring (7-azaindenoisoquinolines) produced the highest selectivity index along with strong DNA topoisomerase IB inhibition, histone H2A phosphorylation and DNA-topoisomerase IB complex stabilization. This report shows for the first time the effect of a series of synthetic indenoisoquinolines on histone H2A phosphorylation, which represents a primary signal of double stranded DNA break in genus Leishmania. N-6 indenoisoquinoline derivatives show strong antileishmanial activity. Indenoisoquinolines arrest Leishmania cell-cycle in S phase. Inhibition of leishmanial TopIB by indenoisoquinolines induces DNA fragmentation. Leishmanial H2A histone is phosphorylated at the Thr128 in response to DNA damage.

Abstract
MYC is one of the most important oncogenes and is overexpressed in the majority of cancers. G-Quadruplexes are noncanonical four-stranded DNA secondary structures that have emerged as attractive cancer-specific molecular targets for drug development. The G-quadruplex formed in the proximal promoter region of the MYC oncogene (MycG4) has been shown to be a transcriptional silencer that is amenable to small-molecule targeting for MYC suppression. Indenoisoquinolines are human topoisomerase I inhibitors in clinical testing with improved physicochemical and biological properties as compared to the clinically used camptothecin anticancer drugs topotecan and irinotecan. However, some indenoisoquinolines with potent anticancer activity do not exhibit strong topoisomerase I inhibition, suggesting a separate mechanism of action. Here, we report that anticancer indenoisoquinolines strongly bind and stabilize MycG4 and lower MYC expression levels in cancer cells, using various biochemical, biophysical, computer modeling, and cell-based methods. Significantly, a large number of active indenoisoquinolines cause strong MYC downregulation in cancer cells. Structure-activity relationships of MycG4 recognition by indenoisoquinolines are investigated. In addition, the analysis of indenoisoquinoline analogues for their MYC-inhibitory activity, topoisomerase I-inhibitory activity, and anticancer activity reveals a synergistic effect of MYC inhibition and topoisomerase I inhibition on anticancer activity. Therefore, this study uncovers a novel mechanism of action of indenoisoquinolines as a new family of drugs targeting the MYC promoter G-quadruplex for MYC suppression. Furthermore, the study suggests that dual targeting of MYC and topoisomerase I may serve as a novel strategy for anticancer drug development.

Abstract
The DNA alkylating prodrug cyclophosphamide (CPA), alone or in combination with other agents, is one of the most commonly used anti-cancer agents. As a prodrug, CPA is activated by cytochrome P450 2B6 (CYP2B6), which is transcriptionally regulated by the human constitutive androstane receptor (hCAR). Therefore, hCAR agonists represent novel sensitizers for CPA-based therapies. Among known hCAR agonists, compound 6-(4-chlorophenyl)imidazo-[2,1-b]thiazole-5-carbaldehyde-O-(3,4-dichlorobenzyl)oxime (CITCO) is the most potent and broadly utilized in biological studies. Through structural modification of CITCO, we have developed a novel compound DL5016 (32), which has an EC50 value of 0.66 μM and EMAX value of 4.9 when activating hCAR. DL5016 robustly induced the expression of hCAR target gene CYP2B6, at both the mRNA and protein levels, and caused translocation of hCAR from the cytoplasm to the nucleus in human primary hepatocytes. The effects of DL5016 were highlighted by dramatically enhancing the efficacy of CPA-based cytotoxicity to non-Hodgkin lymphoma cells.

Abstract
The topoisomerase enzymes play an important role in DNA metabolism, and searching for enzyme inhibitors is an important target in the search for new anticancer drugs. Discovery of new anticancer chemotherapeutical capable of inhibiting topoisomerase enzymes is highlighted in anticancer research. Therefore, biologists, organic chemists and medicinal chemists all around the world have been identifying, designing, synthesizing and evaluating a variety of novel bioactive molecules targeting topoisomerase. This review summarizes types of topoisomerase inhibitors in the past decade, and divides them into nine classes by structural characteristics, including N-heterocycles compounds, quinone derivatives, flavonoids derivatives, coumarin derivatives, lignan derivatives, polyphenol derivatives, diterpenes derivatives, fatty acids derivatives, and metal complexes. Then we discussed the application prospect and development of these anticancer compounds, as well as concluded parts of their structural-activity relationships. We believe this review would be invaluable in helping to further search potential topoisomerase inhibition as antitumor agent in clinical usage.

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
Tyrosyl-DNA phosphodiesterase 1 (TDP1) is a recently discovered enzyme repairing DNA lesions resulting from stalled topoisomerase IB (TOP1)-DNA covalent complex. Inhibiting TDP1 in conjunction with TOP1 inhibitors can boost the action of the latter. Herein, we report the discovery of the natural product oxynitidine scaffold as a novel chemotype for the development of TOP1 and TDP1 inhibitors. Three kinds of analogues, benzophenanthridinone, dihydrobenzophenanthridine, and benzophenanthridine derivatives, were synthesized and evaluated for both TOP1 and TDP1 inhibition and cytotoxicity. Analogue 19a showed high TOP1 inhibition (+++) and induced the formation of cellular TOP1cc and DNA damage, resulting in cancer cells apoptosis at nanomolar concentration range. In vivo studies indicated that 19a exhibits antitumor efficiency in HCT116 xenograft model. 41a exhibited additional TDP1 inhibition with IC50 value of 7 μM and synergistic effect with camptothecin in MCF-7 cells. This work will facilitate future efforts for the discovery of natural product-based TOP1 and TDP1 inhibitors.

Abstract
The 7-azaindenoisoquinolines are cytotoxic topoisomerase I (Top1) inhibitors. Previously reported representatives bear a 3-nitro group. The present report documents the replacement of the potentially genotoxic 3-nitro group by 3-chloro and 3-fluoro substituents, resulting in compounds with high Top1 inhibitory activities and potent cytotoxicities in human cancer cell cultures and reduced lethality in an animal model. Some of the new Top1 inhibitors also possess moderate inhibitory activities against tyrosyl-DNA phosphodiesterase 1 (TDP1) and tyrosyl-DNA phosphodiesterase 2 (TDP2), two enzymes that are involved in DNA damage repair resulting from Top1 inhibitors, and they produce significantly more DNA damage in cancer cells than in normal cells. Eighteen of the new compounds had cytotoxicity mean-graph midpoint (MGM) GI50 values in the submicromolar (0.033-0.630 μM) range. Compounds 16b and 17b are the most potent in human cancer cell cultures with MGM GI50 values of 0.063 and 0.033 μM, respectively. Possible binding modes to Top1 and TDP1were investigated by molecular modeling.

Abstract
Both experimental and computational studies for the cycloaddition reaction between N-(3-pyridyl)aldimines and acetylenes where 1,5-naphthyridines are obtained are reported. The reaction of benzaldimine with a methoxycarbonyl group in position 2 with phenyl acetylene, styrene, and indene afforded polycyclic isoindolone derivatives. The mechanism of reaction of N-(3-pyridyl)aldimines with olefins can be explained by an asynchronous [4+2] cycloaddition; in the case of acetylenes, the obtained results suggest a stepwise mechanism through a 3-azatriene.

Abstract
A series of novel β-elemene isopropanolamine derivatives were synthesized and evaluated for their antitumor activity. The results indicated that all of the compounds showed stronger antiproliferative activities than β-elemene as well as improved aqueous solubility. In particular dimer 6q showed the strongest cytotoxicity against four tumor cell lines (SGC-7901, HeLa, U87 and A549) with IC50 values ranging from 4.37 to 10.20μM. Moreover, combination of 6q with cisplatin exhibited a synergistic effect on these cell lines with IC50 values ranging from 1.21 to 2.94μM, and reversed the resistance of A549/DPP cells with an IC50 value of 2.52μM. The mechanism study revealed that 6q caused cell cycle arrest at the G2 phase and induced apoptosis of SGC-7901 cells through a mitochondrial-dependent apoptotic pathway. Further in vivo study in H22 liver cancer xenograft mouse model validated the antitumor activity of 6q with a tumor inhibitory ratio (TIR) of 60.3%, which was higher than that of β-elemene (TIR, 49.1%) at a dose of 60mg/kg. Altogether, the potent antitumor activity of 6qin vitro and in vivo warranted further preclinical investigation for potential anticancer chemotherapy.

Abstract
Tdp1 and Tdp2 are two tyrosyl-DNA phosphodiesterases that can repair damaged DNA resulting from topoisomerase inhibitors and a variety of other DNA-damaging agents. Both Tdp1 and Tdp2 inhibition could hypothetically potentiate the cytotoxicities of topoisomerase inhibitors. This study reports the successful structure-based design and synthesis of new 7-azaindenoisoquinolines that act as triple inhibitors of Top1, Tdp1, and Tdp2. Enzyme inhibitory data and cytotoxicity data from human cancer cell cultures establish that modification of the lactam side chain of the 7-azaindenoisoquinolines can modulate their inhibitory potencies and selectivities vs Top1, Tdp1, and Tdp2. Molecular modeling of selected target compounds bound to Top1, Tdp1, and Tdp2 was used to design the inhibitors and facilitate the structure-activity relationship analysis. The monitoring of DNA damage by γ-H2AX foci formation in human PBMCs (lymphocytes) and acute lymphoblastic leukemia CCRF-CEM cells documented significantly more DNA damage in the cancer cells vs normal cells.

Abstract
There is a continued desire in biomedical research to reduce the number and duration of design cycles required to optimize lead compounds into high-quality chemical probes or safe and efficacious drug candidates. The insightful application of impactful molecular design elements is one approach toward achieving this goal. The replacement of a CH group with a N atom in aromatic and heteroaromatic ring systems can have many important effects on molecular and physicochemical properties and intra- and intermolecular interactions that can translate to improved pharmacological profiles. In this Perspective, the "necessary nitrogen atom" is shown to be a versatile high-impact design element for multiparameter optimization, wherein ≥10-, 100-, or 1000-fold improvement in a variety of key pharmacological parameters can be realized.

Abstract
DNA topoisomerases are essential during transcription and replication. The therapeutic mechanism of action of topoisomerase inhibitors is enzyme poisoning rather than catalytic inhibition. Tyrosyl-DNA phosphodiesterases 1 or 2 were found as DNA repair enzymes hydrolyzing the covalent bond between the tyrosyl residue of topoisomerases I or II and the 3'- or 5'-phosphate groups in DNA, respectively. Tyrosyl-DNA phosphodiesterase 1 is a key enzyme in DNA repair machinery and a promising target for antitumor and neurodegenerative therapy. Inhibitors of tyrosyl-DNA phosphodiesterase 1 could act synergistically with topoisomerase I inhibitors and thereby potentiate the effects of topoisomerase I poisons. Tyrosyl-DNA phosphodiesterase 2 is an enzyme that specifically repairs DNA damages induced by topoisomerase II poisons and causes resistance to these drugs. Selective inhibition of tyrosyl-DNA phosphodiesterase 2 may be a novel approach to overcome intrinsic or acquired resistance to topoisomerase II-targeted drug therapy. Thus, agents that inhibit tyrosyl-DNA phosphodiesterases 1 and 2 have many applications in biochemical and physiological research and they have the potential to become anticancer and antiviral drugs. The structures, mechanism of action and therapeutic rationale of tyrosyl-DNA phosphodiesterase inhibitors and their development for combinations with topoisomerase inhibitors and DNA damaging agents are discussed.

Abstract
Indenoisoquinoline topoisomerase I (Top1) inhibitors are a novel class of anticancer agents with two compounds in clinical trials. Recent metabolism studies of indotecan (LMP400) led to the discovery of the biologically active 2-hydroxylated analogue and 3-hydroxylated metabolite, thus providing strategically placed functional groups for the preparation of a variety of potential ester prodrugs of these two compounds. The current study details the design and synthesis of two series of indenoisoquinoline prodrugs, and it also reveals how substituents on the O-2 and O-3 positions of the A ring, which are next to the cleaved DNA strand in the drug-DNA-Top1 ternary cleavage complex, affect Top1 inhibitory activity and cytotoxicity. Many of the indenoisoquinoline prodrugs were very potent antiproliferative agents with GI50 values below 10 nM in a variety of human cancer cell lines.

Abstract
Several indenoisoquinolines have shown promise as anticancer agents in clinical trials. Incorporation of a nitrogen atom into the indenoisoquinoline scaffold offers the possibility of favorably modulating ligand-binding site interactions, physicochemical properties, and biological activities. Four series of aza-A-ring indenoisoquinolines were synthesized in which the nitrogen atom was systematically rotated through positions 1, 2, 3, and 4. The resulting compounds were tested to establish the optimal nitrogen position for topoisomerase IB (Top1) enzyme poisoning activity and cytotoxicity to human cancer cells. The 4-aza compounds were the most likely to yield derivatives with high Top1 inhibitory activity. However, the relationship between structure and cytotoxicity was more complicated since the potency was influenced strongly by the side chains on the lactam nitrogen. The most cytotoxic azaindenoisoquinolines 45 and 46 had nitrogen in the 2- or 3-positions and a 3'-dimethylaminopropyl side chain, and they had MGM GI50 values that were slightly better than the corresponding indenoisoquinoline 64.

Abstract
Exchange proteins directly activated by cAMP (EPAC) as guanine nucleotide exchange factors mediate the effects of the pivotal second messenger cAMP, thereby regulating a wide variety of intracellular physiological and pathophysiological processes. A series of novel 2-(isoxazol-3-yl)-2-oxo-N'-phenyl-acetohydrazonoyl cyanide EPAC antagonists was synthesized and evaluated in an effort to optimize properties of the previously identified high-throughput (HTS) hit 1 (ESI-09). Structure-activity relationship (SAR) analysis led to the discovery of several more active EPAC antagonists (e.g., 22 (HJC0726), 35 (NY0123), and 47 (NY0173)) with low micromolar inhibitory activity. These inhibitors may serve as valuable pharmacological probes to facilitate our efforts in elucidating the biological functions of EPAC and developing potential novel therapeutics against human diseases. Our SAR results have also revealed that further modification at the 3-, 4-, and 5-positions of the phenyl ring as well as the 5-position of the isoxazole moiety may allow for the development of more potent EPAC antagonists.

Abstract
The structure-activity relationships and hit-to-lead optimization of dual Top1-TDP1 inhibitors in the indenoisoquinoline drug class were investigated. A series of nitrated 7-, 8-, 9-, and 10-hydroxyindenoisoquinolines were synthesized and evaluated. Several compounds displayed potent dual Top1-TDP1 inhibition. The 9-hydroxy series exhibited potencies and cytotoxicities vs Top1 that surpassed those of camptothecin (CPT), the natural alkaloid that is being used as a standard in the Top1-mediated DNA cleavage assay. One member of this series was a more potent Top1 inhibitor at a concentration of 5 nM and produced a more stable ternary drug-DNA-Top1 cleavage complex than CPT.

Abstract
![]()
Tyrosyl-DNA
phosphodiesterase I (TDP1) repairs stalled topoisomerase
I (Top1)–DNA covalent complexes and has been proposed to be
a promising and attractive target for cancer treatment. Inhibitors
of TDP1 could conceivably act synergistically with Top1 inhibitors
and thereby potentiate the effects of Top1 poisons. This study describes
the successful design and synthesis of 2-position-modified indenoisoquinolines
as dual Top1–TDP1 inhibitors using a structure-based drug design
approach. Enzyme inhibition studies indicate that indenoisoquinolines
modified at the 2-position with three-carbon side chains ending with
amino substituents show both promising Top1 and TDP1 inhibitory activity.
Molecular modeling of selected target compounds bound to Top1 and
TDP1 was used to rationalize the enzyme inhibition results and structure–activity
relationship analysis.

Abstract
Optimization of the lactam ω-aminoalkyl substituents in a series of 7-azaindenoisoquinolines resulted in new anticancer agents with improved Top1 inhibitory potencies and cancer cell cytotoxicities. The new compounds 14-17 and 19 exhibited mean graph midpoint cytotoxicity (GI50) values of 21-71 nM in the NCI panel of 60 human cancer cell cultures. Ternary 7-azaindenoisoquinoline-DNA-Top1 cleavage complexes that persist for up to 6 h were detected in HCT116 colon cancer cells. Ternary complexes containing 7-azaindenoisoquinolines were significantly more stable than those in which camptothecin was incorporated. DNA content distribution histograms showed S-phase block 3 h after drug removal. Drug-induced DNA damage in HCT116 cells was revealed by induction of the histone γ-H2AX marker. The 7-azaindenoisoquinolines were able to partially overcome resistance in several drug-resistant cell lines, and they were not substrates for the ABCB1 drug efflux transporter. Molecular modeling studies indicate that the 7-azaindenoisoquinolines intercalate at the DNA cleavage site in DNA-Top1 covalent complexes with the lactam side chain projecting into the major groove. Overall, the results indicate that the 7-azaindenoisoquinolines are promising anticancer agents that merit further development.

Abstract
Oridonin (1), a complex ent-kaurane diterpenoid isolated from the traditional Chinese herb Isodon rubescens , has demonstrated great potential in the treatment of various human cancers due to its unique and safe anticancer pharmacological profile. Nevertheless, the clinical development of oridonin for cancer therapy has been hampered by its relatively moderate potency, limited aqueous solubility, and poor bioavailability. Herein, we report the concise synthesis of a series of novel nitrogen-enriched oridonin derivatives with thiazole-fused A-ring through an efficient protecting group-free synthetic strategy. Most of them, including compounds 7-11, 13, and 14, exhibited potent antiproliferative effects against breast, pancreatic, and prostate cancer cells with low micromolar to submicromolar IC50 values as well as markedly enhanced aqueous solubility. These new analogues obtained by rationally modifying the natural product have been demonstrated not only to significantly induce the apoptosis and suppress growth of triple-negative MDA-MB-231 breast cancer both in vitro and in vivo but also effective against drug-resistant ER-positive MCF-7 clones.

Abstract
Tyrosyl-DNA phosphodiesterase I (Tdp1) plays a key role in the repair of damaged DNA resulting from the topoisomerase I (Top1) inhibitor camptothecin and a variety of other DNA-damaging anticancer agents. This report documents the design, synthesis, and evaluation of new indenoisoquinolines that are dual inhibitors of both Tdp1 and Top1. Enzyme inhibitory data and cytotoxicity data from human cancer cell cultures were used to establish structure-activity relationships. The potencies of the indenoisoquinolines against Tdp1 ranged from 5 μM to 111 μM, which places the more active compounds among the most potent known inhibitors of this target. The cytotoxicity mean graph midpoints ranged from 0.02 to 2.34 μM. Dual Tdp1-Top1 inhibitors are of interest because the Top1 and Tdp1 inhibitory activities could theoretically work synergistically to create more effective anticancer agents.
