Abstract
Target engagement and the biodistribution of exogenously administered small molecules is rarely homogenous. Methods to determine the biodistribution at the cellular level are limited by the ability to detect the small molecule and simultaneously identify the cell types or tissue structures with which it is associated. The highly multiplexed nature of mass cytometry could facilitate these studies provided a heavy isotope label was available in the molecule of interest. Here we show it is possible to append a tellurophene to a known chemotherapeutic, teniposide, to follow this molecule in vivo . A semi-synthetic approach offers an efficient route to the teniposide analogue which is found to have indistinguishable characteristics when compared with the parent teniposide in vitro . Using mass cytometry and imaging mass cytometry we find the teniposide analogue has significant non-specific binding to cells. In vivo the tellurium bearing teniposide produces the expected DNA damage in a PANC-1 xenograft model. The distribution of Te in the tissue is near the limits of detection and further work will be required to characterize the localization of this analogue with respect to cell type distributions.

Abstract
Aim: This paper presents the reported dermatological adverse events (AEs) associated with approved combinations of immunotherapy with drugs of the same class, or in combination with targeted therapy or chemotherapy. Materials & methods: PubMed was used as an electronic database, and a total of 29 articles were reviewed which reported dermatological AEs following combination therapies with nivolumab, ipilimumab, axitinib, pembrolizumab, lenvatinib, avelumab, atezolizumab, carboplatin, etoposide, paclitaxel, bevacizumab, pemetrexed, cisplatin and durvalumab. Results: The dermatological AEs reported were mutually inclusive and the highest incidence of specific AEs was seen in the following combinations: rash in the nivolumab/ipilimumab and lenvatinib/pembrolizumab combinations, pruritus in the atezolizumab/nab-paclitaxel combination, dry skin and palmar-plantar erythrodysesthesia in the axitinib/pembrolizumab combination, and alopecia and severe skin reactions in the pembrolizumab/carboplatin/paclitaxel combination. Conclusion: Knowledge of such side effects is of benefit when choosing an optimal treatment regimen and should be integrated into the monitoring and follow-up phases of treatment.

Abstract
DNA-protein crosslinks (DPCs) and DNA double-stranded breaks (DSBs), including those produced by stalled topoisomerase 2 cleavage complexes (TOP2ccs), must be repaired to ensure genome stability. The basic mechanisms of TOP2cc repair have been characterized in other eukaryotes, but we lack information for plants. Using CRISPR/Cas-induced mutants, we show that Arabidopsis thaliana has two main TOP2cc repair pathways: one is defined by TYROSYL-DNA-PHOSPHODIESTERASE 2 (TDP2), which hydrolyzes TOP2-DNA linkages, the other by the DNA-dependent protease WSS1A (a homolog of human SPARTAN/yeast weak suppressor of smt3 [Wss1]), which also functions in DPC repair. TDP1 and TDP2 function nonredundantly in TOP1cc repair, indicating that they act specifically on their respective stalled cleavage complexes. The nuclease METHYL METHANESULFONATE AND UV-SENSITIVE PROTEIN 81 (MUS81) plays a major role in global DPC repair and a minor role in TOP2cc repair. DSBs arise as intermediates of TOP2cc repair and are repaired by classical and alternative nonhomologous end joining (NHEJ) pathways. Double-mutant analysis indicates that "clean" DNA ends caused by TDP2 hydrolysis are mainly religated by classical NHEJ, which helps avoid mutation. In contrast, the mutagenic alternative NHEJ pathway mainly processes nonligateable DNA ends. Thus, TDP2 promotes maintenance of plant genome integrity by error-free repair of TOP2cc.

Abstract
Etoposide is a semi-synthetic glycoside derivative of podophyllotoxin, also known as VP-16. It is a widely used anticancer medicine in clinics. Unfortunately, high doses or long-term etoposide treatment can induce therapy-related leukemia. The mechanism by which etoposide induces secondary hematopoietic malignancies is still unclear. In this article, we review the potential mechanisms of etoposide induced therapy-related leukemia. Etoposide related leukemogenesis is known to depend on reactive oxidative metabolites of etoposide, notably etoposide quinone, which interacts with cellular proteins such as topoisomerases II (TOP2), CREB-binding protein (CREBBP), and T-Cell Protein Tyrosine Phosphatase (TCPTP). CYP3A4 and CYP3A5 metabolize etoposide to etoposide catechol, which readily oxidizes to etoposide quinone. As a poison of TOP2 enzymes, etoposide and its metabolites induce DNA double-stranded breaks (DSB), and the accumulation of DSB triggers cell apoptosis. If the cell survives, the DSB gives rise to the likelihood of faulty DNA repair events. The gene translocation could occur in mixed-lineage leukemia (MLL) gene, which is well-known in leukemogenesis. Recently, studies have revealed that etoposide metabolites, especially etoposide quinone, can covalently bind to cysteines residues of CREBBP and TCPTP enzymes, . This leads to enzyme inhibition and further affects histone acetylation and phosphorylation of the JAK-STAT pathway, thus putatively altering the proliferation and differentiation of hematopoietic stem cells (HSC). In brief, current studies suggest that etoposide and its metabolites contribute to etoposide therapy-related leukemia through TOP2 mediated DSB and impairs specific enzyme activity, such as CREBBP and TCPTP.

Abstract
1,2-Naphthoquinone, a secondary metabolite of naphthalene, is an environmental pollutant found in diesel exhaust particles that displays cytotoxic and genotoxic properties. Because many quinones have been shown to act as topoisomerase II poisons, the effects of this compound on DNA cleavage mediated by human topoisomerase IIα and IIβ were examined. The compound increased the levels of double-stranded DNA breaks generated by both enzyme isoforms and did so better than a series of naphthoquinone derivatives. Furthermore, 1,2-naphthoquinone was a more efficacious poison against topoisomerase IIα than IIβ. Topoisomerase II poisons can be classified as interfacial (which interact noncovalently at the enzyme-DNA interface and increase DNA cleavage by blocking ligation) or covalent (which adduct the protein and increase DNA cleavage by closing the N-terminal gate of the enzyme). Therefore, experiments were performed to determine the mechanistic basis for the actions of 1,2-naphthoquinone. In contrast to results with etoposide (an interfacial poison), the activity of 1,2-naphthoquinone against topoisomerase IIα was abrogated in the presence of sulfhydryl and reducing agents. Moreover, the compound inhibited cleavage activity when incubated with the enzyme prior to the addition of DNA and induced virtually no cleavage with the catalytic core of the enzyme. It also induced stable covalent topoisomerase IIα-DNA cleavage complexes and was a partial inhibitor of DNA ligation. Findings were also consistent with 1,2-naphthoquinone acting as a covalent poison of topoisomerase IIβ; however, mechanistic studies with this isoform were less conclusive. Whereas the activity of 1,2-naphthoquinone was blocked in the presence of a sulfhydryl reagent, it was much less sensitive to the presence of a reducing agent. Furthermore, the reduced form of 1,2-naphthoquinone, 1,2-dihydroxynaphthalene, displayed high activity against the β isoform. Taken together, results suggest that 1,2-naphthoquinone increases topoisomerase II-mediated double-stranded DNA scission (at least in part) by acting as a covalent poison of the human type II enzymes.

Abstract
Etoposide is an extensively prescribed anticancer drug that, unfortunately, causes therapy-related leukemia. The mechanisms by which etoposide induces secondary hematopoietic malignancies are poorly documented. However, etoposide-related leukemogenesis is known to depend on oxidative metabolites of etoposide, notably etoposide quinone, that can react with protein cysteine residues such as in topoisomerases II. CREBBP is a major histone acetyltransferase that functions mainly as a transcriptional co-activator. This epigenetic enzyme is considered as a tumor suppressor that plays a major role in hematopoiesis. Genetic alterations affecting CREBBP activity are highly common in hematopoietic malignancies. We report here that CREBBP is impaired by etoposide quinone. Molecular and kinetic analyses show that this inhibition occurs through the rapid and covalent (kinhib = 16.102 M-1. s-1) adduction of etoposide quinone with redox sensitive cysteine residues within the RING and PHD Zn2+-fingers of CREBBP catalytic core leading to subsequent release of Zn2+. In agreement with these findings, experiments conducted in cells and in mice treated with etoposide showed irreversible inhibition of endogenous CREBBP activity and decreased H3K18 and H3K27 acetylation. As shown for topoisomerases II, our work thus suggests that the leukemogenic metabolite etoposide quinone can impair the epigenetic CREBBP acetyltransferase through reaction with redox sensitive cysteine residues.

Abstract
We developed a new strategy to overcome the MDR of etoposide using self-assembling nanofibers. Compared with the original etoposide, the inhibitory activity of Nap-GFFpYK-etoposide1/2 against murine Lewis lung cancer or breast cancer cells was increased 10 times, and 20 times on these cells with artificially overexpressed MDR1. Our method to synthesize and separate etoposide isomers provides a new strategy for the modification of this drug.

Abstract
FAM122A is a housekeeping gene and highly conserved in mammals. More recently, we have demonstrated that FAM122A is essential for maintaining the growth of hepatocellular carcinoma cells, in which we unexpectedly found that FAM122A deletion increases γH2AX protein level, suggesting that FAM122A may participate in the regulation of DNA homeostasis or stability. In this study, we continued to investigate the potential role of FAM122A in DNA damage and/or repair. We found that CRISPR/Cas9-mediated FAM122A deletion enhances endogenous DNA damages in cancer cells but not in normal cells, demonstrating a significant increase in γH2AX protein and foci formation of γH2AX and 53BP1, as well as DNA breaks by comet assay. Further, we found that FAM122A deletion greatly increases TOP2α protein level, and significantly and specifically enhances TOP2 poisons (etoposide and doxorubicin)-induced DNA damage effects in cancer cells. Moreover, FAM122A is found to be interacted with TOP2α, instead of TOP2β. However, FAM122A knockout doesn't affect the intracellular ROS levels and the process of DNA repair after removal of etoposide with short-term stimulation, suggesting that FAM122A deletion-enhanced DNA damage does not result from endogenous overproduction of ROS and/or impairment of DNA repair ability. Collectively, our study provides the first demonstration that FAM122A is critical for maintaining DNA stability probably by modulating TOP2α protein, and FAM122A deletion combined with TOP2-targeted drugs may represent a potential novel chemotherapeutic strategy for cancer patients.

Abstract
Etoposide is a widely-used anticancer agent that targets human type II topoisomerases. Evidence suggests that metabolism of etoposide in myeloid progenitor cells is associated with translocations involved in leukemia development. Previous studies suggest halogenation at the C-2' position of etoposide reduces metabolism. Halogens were introduced into the C-2' position by electrophilic aromatic halogenation onto etoposide (ETOP, 1), podophyllotoxin (PPT, 2), and 4-dimethylepipodophyllotoxin (DMEP, 3), and to bridge the gap of knowledge regarding the activity of these metabolically stable analogs. Five halogenated analogs (6-10) were synthesized. Analogs 8-10 displayed variable ability to inhibit DNA relaxation. Analog 9 was the only analog to show concentration-dependent enhancement of Top2-mediated DNA cleavage. Dose response assay results indicated that 8 and 10 were most effective at decreasing the viability of HCT-116 and A549 cancer cell lines in culture. Flow cytometry with 8 and 10 in HCT-116 cells provide evidence of sub-G1 cell populations indicative of apoptosis. Taken together, these results indicate C-2' halogenation of etoposide and its precursors, although metabolically stable, decreases overall activity relative to etoposide.

Abstract
![]()
We
previously reported a first set of hybrid topoisomerase II (topoII)
poisons whose chemical core merges key pharmacophoric elements of
etoposide and merbarone, which are two well-known topoII blockers.
Here, we report on the expansion of this hybrid molecular scaffold
and present 16 more hybrid derivatives that have been designed, synthesized,
and characterized for their ability to block topoII and for their
overall drug-like profile. Some of these compounds act as topoII poison
and exhibit good solubility, metabolic (microsomal) stability, and
promising cytotoxicity in three cancer cell lines (DU145, HeLa, A549).
Compound 3f (ARN24139) is the most promising drug-like
candidate, with a good pharmacokinetics profile in vivo. Our results indicate that this hybrid new chemical class of topoII
poisons deserves further exploration and that 3f is a
favorable lead candidate as a topoII poison, meriting future studies
to test its efficacy in in vivo tumor models.

Abstract
Topoisomerase II is a nuclear enzyme involved in the maintenance of DNA and is an effective anticancer drug target. However, several clinical topoisomerase II-targeted agents display significant off-target toxicities and adverse events. Thus, it is important to continue characterizing compounds with activity against topoisomerase II. We previously analyzed α-(N)-heterocyclic thiosemicarbazone copper(II) complexes against human topoisomerase IIα (TOP2A), but humans also express topoisomerase IIβ (TOP2B), which has distinct functional roles. Therefore, we examined two α-(N)-heterocyclic thiosemicarbazone copper [Cu(II)] complexes for activity against TOP2B in a purified system. The Cu(II) complexes, Cu(APY-ETSC)Cl and Cu(BZP-ETSC)Cl, were examined using plasmid DNA cleavage, supercoiled DNA relaxation, enzyme inactivation, protein cross-linking, DNA ligation, and ATP hydrolysis assays with TOP2B to determine whether these compounds act similarly against both enzymes. Both of the Cu(II) thiosemicarbazone (Cu-TSC) complexes we tested disrupted the function of TOP2B in a way similar to the effect on TOP2A. In particular, TOP2B DNA cleavage activity is increased in the presence of these compounds, while the relaxation and ATPase activities are inhibited. Further, both Cu-TSCs stabilize the N-terminal DNA clamp of TOP2A and TOP2B and rapidly inactivate TOP2B when the compounds are present before DNA. Our data provide evidence that the Cu-TSC complexes we tested utilize a similar mechanism against both isoforms of the enzyme. This mechanism may involve interaction with the ATPase domain of TOP2A and TOP2B outside of the ATP binding pocket. Additionally, these data support a model of TOP2 function where the ATPase domain communicates with the DNA cleavage/ligation domain.

Abstract
![]()
Human
type II topoisomerases (TopoII) are essential for controlling
DNA topology within the cell. For this reason, there are a number
of TopoII-targeted anticancer drugs that act by inducing DNA cleavage
mediated by both TopoII isoforms (TopoIIα and TopoIIβ)
in cells. However, recent studies suggest that specific poisoning
of TopoIIα may be a safer strategy for treating cancer. This
is because poisoning of TopoIIβ appears to be linked to the
generation of secondary leukemia in patients. We recently reported
that enzyme-mediated DNA cleavage complexes (in which TopoII is covalently
linked to the cleaved DNA during catalysis) formed in the presence
of the anticancer drug etoposide persisted approximately 3-fold longer
with TopoIIα than TopoIIβ. Notably, enhanced drug-target
residence time may reduce the adverse effects of specific TopoIIα
poisons. However, it is still not clear how to design drugs that are
specific for the α isoform. In this study, we report the results
of classical molecular dynamics (MD) simulations to comparatively
analyze the molecular interactions formed within the TopoII/DNA/etoposide
complex with both isoforms. We also used smoothed potential MD to
estimate etoposide dissociation kinetics from the two isoform complexes.
These extensive classical and enhanced sampling simulations revealed
stabilizing interactions of etoposide with two serine residues (Ser763
and Ser800) in TopoIIα. These interactions are missing in TopoIIβ,
where both amino acids are alanine residues. This may explain the
greater persistence of etoposide-stabilized cleavage complexes formed
with Topo TopoIIα. These findings could be useful for the rational
design of specific TopoIIα poisons.

Targeting DNA Replication Stress and DNA Double-Strand Break Repair for Optimizing SCLC Treatment. Cancers (Basel) 2019; 11:cancers11091289.

Abstract
Small cell lung cancer (SCLC), accounting for about 15% of all cases of lung cancer worldwide, is the most lethal form of lung cancer. Despite an initially high response rate of SCLC to standard treatment, almost all patients are invariably relapsed within one year. Effective therapeutic strategies are urgently needed to improve clinical outcomes. Replication stress is a hallmark of SCLC due to several intrinsic factors. As a consequence, constitutive activation of the replication stress response (RSR) pathway and DNA damage repair system is involved in counteracting this genotoxic stress. Therefore, therapeutic targeting of such RSR and DNA damage repair pathways will be likely to kill SCLC cells preferentially and may be exploited in improving chemotherapeutic efficiency through interfering with DNA replication to exert their functions. Here, we summarize potentially valuable targets involved in the RSR and DNA damage repair pathways, rationales for targeting them in SCLC treatment and ongoing clinical trials, as well as possible predictive biomarkers for patient selection in the management of SCLC.

Abstract
The formation of o-quinones from direct 2-electron oxidation of catechols and/or two successive one electron oxidations could explain the cytotoxic/genotoxic and/or chemopreventive effects of several phenolic botanical extracts. For example, poison ivy contains urushiol, an oily mixture, which is oxidized to various o-quinones likely resulting in skin toxicity through oxidative stress and alkylation mechanisms resulting in immune responses. Green tea contains catechins which are directly oxidized to o-quinones by various oxidative enzymes. Alternatively, phenolic botanicals could be o-hydroxylated by P450 to form catechols in vivo which are oxidized to o-quinones. Examples include, resveratrol which is oxidized to piceatannol and further oxidized to the o-quinone. Finally, botanical o-quinones can be formed by O-dealkylation of O-alkoxy groups or methylenedioxy rings resulting in catechols which are further oxidized to o-quinones. Examples include safrole, eugenol, podophyllotoxin and etoposide, as well as methysticin. Once formed these o-quinones have a variety of biological targets in vivo resulting in various biological effects ranging from chemoprevention - > no effect - > toxicity. This U-shaped biological effect curve has been described for a number of reactive intermediates including o-quinones. The current review summarizes the latest data on the formation and biological targets of botanical o-quinones.

Abstract
Topoisomerase II is a critical enzyme in replication, transcription, and the regulation of chromatin topology. Several anticancer agents target topoisomerases in order to disrupt cell growth. Cannabidiol is a major non-euphoriant, pharmacologically active component of cannabis. Previously, we examined the cannabidiol derivative HU-331 in order to characterize the mechanism of the compound against topoisomerase IIα. In this current work, we explore whether cannabidiol (CBD) impacts topoisomerase II activity, and we additionally examine the activity of these compounds against topoisomerase IIβ. CBD does not appear to strongly inhibit DNA relaxation and is not a poison of topoisomerase II DNA cleavage. However, oxidation of CBD allows this compound to inhibit DNA relaxation by topoisomerase IIα and β without poisoning DNA cleavage. Additionally, we found that oxidized CBD, similar to HU-331, inhibits ATP hydrolysis and can result in inactivation of topoisomerase IIα and β. We also determined that oxidized CBD and HU-331 are both able to stabilize the N-terminal clamp of topoisomerase II. Taken together, we conclude that while CBD does not have significant activity against topoisomerase II, both oxidized CBD and HU-331 are active against both isoforms of topoisomerase II. We hypothesize that oxidized CBD and HU-331 act against the enzyme through interaction with the N-terminal ATPase domain. According to the model we propose, topoisomerase II inactivation may result from a decrease in the ability of the enzyme to bind to DNA when the compound is bound to the N-terminus.

Abstract
DNA replication is a highly demanding process regarding the energy and material supply and must be precisely regulated, involving multiple cellular feedbacks. The slowing down or stalling of DNA synthesis and/or replication forks is referred to as replication stress (RS). Owing to the complexity and requirements of replication, a plethora of factors may interfere and challenge the genome stability, cell survival or affect the whole organism. This review outlines chemical compounds that are known inducers of RS and commonly used in laboratory research. These compounds act on replication by direct interaction with DNA causing DNA crosslinks and bulky lesions (cisplatin), chemical interference with the metabolism of deoxyribonucleotide triphosphates (hydroxyurea), direct inhibition of the activity of replicative DNA polymerases (aphidicolin) and interference with enzymes dealing with topological DNA stress (camptothecin, etoposide). As a variety of mechanisms can induce RS, the responses of mammalian cells also vary. Here, we review the activity and mechanism of action of these compounds based on recent knowledge, accompanied by examples of induced phenotypes, cellular readouts and commonly used doses.
