A clickable melphalan for monitoring DNA interstrand crosslink accumulation and detecting ICL repair defects in Fanconi anemia patient cells. Nucleic Acids Res 2023; 51:7988-8004.

Abstract
Fanconi anemia (FA) is a genetic disorder associated with developmental defects, bone marrow failure and cancer. The FA pathway is crucial for the repair of DNA interstrand crosslinks (ICLs). In this study, we have developed and characterized a new tool to investigate ICL repair: a clickable version of the crosslinking agent melphalan which we name click-melphalan. Our results demonstrate that click-melphalan is as effective as its unmodified counterpart in generating ICLs and associated toxicity. The lesions induced by click-melphalan can be detected in cells by post-labelling with a fluorescent reporter and quantified using flow cytometry. Since click-melphalan induces both ICLs and monoadducts, we generated click-mono-melphalan, which only induces monoadducts, in order to distinguish between the two types of DNA repair. By using both molecules, we show that FANCD2 knock-out cells are deficient in removing click-melphalan-induced lesions. We also found that these cells display a delay in repairing click-mono-melphalan-induced monoadducts. Our data further revealed that the presence of unrepaired ICLs inhibits monoadduct repair. Finally, our study demonstrates that these clickable molecules can differentiate intrinsic DNA repair deficiencies in primary FA patient cells from those in primary xeroderma pigmentosum patient cells. As such, these molecules may have potential for developing diagnostic tests.

Abstract
Platinum-acridine anticancer agents (PAs) containing acyclic (1 and 3) and heterocyclic (R)-3-aminopiperidine (2) and 2-iminopyrrolidine (4) based linker moieties were studied. Similar to 1, rigidified 2 shows a strong positive correlation between potency and SLC47A1 (multidrug and toxin extrusion protein 1, MATE1) gene expression levels across the NCI-60 panel of cancer cell lines. All derivatives show nanomolar activity in HepG2 (liver), NCI-H460 (lung), and MDA-MB-436 (breast), which express high levels of SLC47A1 (Cancer Cell Line Encyclopedia, CCLE). The PAs are up to 350-fold more potent than cisplatin. In a MATE1 inhibition assay, a significant reduction in activity is observed in the three cancer cell lines (4000-fold lower for HepG2). Molecular docking experiments provide insight into the compatibility of the structurally diverse set of PAs with MATE1-mediated transport. MATE1 is a predictive marker and actionable target that sensitizes cancer cells regardless of the tissue of origin to PAs.

Abstract
In this study, we provide crystallographic (Protein Data Bank (PDB) inspection) and theoretical (RI-MP2/def2-TZVP//PBE0-D3/def2-SVP level of theory) evidence of the involvement of nucleobases in Regium-π bonds (RgBs). This noncovalent interaction involves an electrophilic site located on an element of group 11 (Cu, Ag, and Au) and an electron-rich species (lone pair, LP donor, or π-system). Concretely, an initial PDB search revealed several examples where RgBs were undertaken involving DNA bases and Cu(II), Ag(I), and Au(I/III) ions. While coordination positions (mainly at the N atoms of the base) are well known, the noncovalent binding force between these counterparts has been scarcely studied in the literature. In this regard, computational models shed light on the strength and directionality properties of the interaction, which was also further characterized from a charge-density perspective using Bader's "atoms in molecules" (AIM) theory, noncovalent interaction plot (NCIplot) visual index, and natural bonding orbital (NBO) analyses. As far as our knowledge extends, this is the first time that RgBs in metal-DNA complexes are systematically analyzed, and we believe the results might be useful for scientists working in the field of nucleic acid engineering and chemical biology as well as to increase the visibility of the interaction among the biological community.

Abstract
NCI-60 growth inhibition and gene expression profiles were analyzed using Pearson correlation and functional enrichment computational tools to demonstrate critical mechanistic differences between a nucleolus-targeting platinum-acridine anticancer agent (PA) and other DNA-directed chemotherapies. The results support prior experimental data and are consistent with DNA being a major target of the hybrid agent based on the negative correlations observed between its potency and expression levels of genes implicated in DNA double-strand break (DSB) repair. Gene ontology terms related to RNA processing, including ribosome biogenesis, are also negatively enriched, suggesting a mechanism by which these processes render cancer cells more resistant to the highly cytotoxic agent. The opposite trend is observed for oxaliplatin and other DNA-targeted drugs. Significant functional interactions exist between genes/gene products involved in ribosome biogenesis and DSB repair, including the ribosomal protein (RPL5)-MDM2-p53 surveillance pathway, as a response to the nucleolar stress produced by PAs.

Abstract
DNA G-quadruplexes in human telomeres and gene promoters are being extensively studied for their role in controlling the growth of cancer cells. G-quadruplexes have been unambiguously shown to exist both in vitro and in vivo, including in the guanine (G)-rich DNA genes encoding pre-ribosomal RNA (pre-rRNA), which is transcribed in the cell's nucleolus. Recent studies strongly suggest that these DNA sequences ("rDNA"), and the transcribed rRNA, are a potential anticancer target through the inhibition of RNA polymerase I (Pol I) in ribosome biogenesis, but the structures of ribosomal G-quadruplexes at atomic resolution are unknown and very little biophysical characterization has been performed on them to date. In the present study, circular dichroism (CD) spectroscopy is used to show that two putative rDNA G-quadruplex sequences, NUC 19P and NUC 23P and their counterpart rRNAs, predominantly adopt parallel topologies, reminiscent of the analogous telomeric quadruplex structures. Based on this information, we modeled parallel topology atomistic structures of the putative ribosomal G-quadruplexes. We then validated and refined the modeled ribosomal G-quadruplex structures using all-atom molecular dynamics (MD) simulations with the CHARMM36 force field in the presence and absence of stabilizing K+. Motivated by preliminary MD simulations of the telomeric parallel G-quadruplex (TEL 24P) in which the K+ ion is expelled, we used updated CHARMM36 force field K+ parameters that were optimized, targeting the data from quantum mechanical calculations and the polarizable Drude model force field. In subsequent MD simulations with optimized CHARMM36 parameters, the K+ ions are predominantly in the G-quadruplex channel and the rDNA G-quadruplexes have more well-defined, predominantly parallel-topology structures as compared to rRNA. In addition, NUC 19P is more structured than NUC 23P, which contains extended loops. Results from this study set the structural foundation for understanding G-quadruplex functions and the design of novel chemotherapeutics against these nucleolar targets and can be readily extended to other DNA and RNA G-quadruplexes.

Abstract
To study the DNA damage caused by a potent platinum-acridine anticancer agent (PA) in cancer cells, an assay based on biorthogonal post-labeling using a click chemistry-enabled, azide-modified derivative (APA) was developed. The method involves biotinylation, affinity capture, and bead-based enrichment of APA-modified genomic DNA. The key steps of the assay were validated and optimized in model duplexes, including full-length plasmids, restriction fragments, and a DNA ladder. Native DNA treated with APA and subsequently subjected to post-labeling with a biotin affinity tag was enzymatically digested and fragments were analyzed by in-line LC-MS and MS/MS. The monofunctional-intercalative adducts formed by APA in 5´-pyrimidine/guanine sequences in double-stranded DNA are quantitatively biotinylated by strain-promoted 1,3-dipolar cycloaddition chemistry. When applied to DNA extracted from A549 lung cancer cells, the assay in combination with qPCR amplification demonstrates that platinum-acridines form adducts in the gene sequences encoding pre-ribosomal RNA, a potential pharmacological target of these agents.

Abstract
A structure-activity relationship study was performed for a set of rigidified platinum-acridine anticancer agents containing linkers derived from chiral pyrrolidine and piperidine scaffolds. Screening a library of microscale reactions and selected resynthesized compounds in non-small-cell lung cancer (NSCLC) cells showed that cytotoxicities varied by more than three orders of magnitude. A potent hit compound was discovered containing a (R)-N-(piperidin-3-yl) linker (P2-6R), which killed NCI-H460 and A549 lung cancer cells 100 times more effectively than the S enantiomer (P2-6S). P2-6R accumulated in A549 cells significantly faster and produced 50-fold higher DNA adduct levels than P2-6S. Ligand similarity analysis suggests that only module 6R may be compatible with strainless monofunctional intercalative binding. NCI-60 screening and COMPARE analysis highlights the spectrum of activity and potential utility of P2-6R for treating NSCLC and other solid tumors.

Abstract
Click chemistry is fundamentally important to medicinal chemistry and chemical biology. It represents a powerful and versatile tool, which can be exploited to develop novel Pt-based anticancer drugs and to better understand the biological effects of Pt-based anticancer drugs at a cellular level. Innovative azide-alkyne cycloaddition-based approaches are being used to functionalise Pt-based complexes with biomolecules to enhance tumour targeting. Valuable information in relation to the mechanisms of action and resistance of Pt-based drugs is also being revealed through click-based detection, isolation and tracking of Pt drug surrogates in biological and cellular environments. Although less well-explored, inorganic Pt-click reactions enable synthesis of novel (potentially multimetallic) Pt complexes and provide plausible routes to introduce functional groups and monitoring Pt-azido drug localisation.

Abstract
The majority of cancer-associated deaths are related to secondary tumor formation. This multistep process involves the migration of cancer cells to anatomically distant organs. Metastasis formation relies on cancer cell dissemination and survival in the circulatory system, as well as adaptation to the new tissue notably through genetic and/or epigenetic alterations. A large number of proteins are clearly identified to play a role in the metastatic process but the structures and modes of action of these proteins are essentially unknown or poorly described. In this review, we detail the involvement of members of the transmembrane (TMEM) protein family in the formation of metastases or in the mechanisms leading to cancer cell dissemination such as migration and extra-cellular matrix remodelling. While the phenotype associated with TMEM over or down-expression is clear, the mechanisms by which these proteins allow cancer cell spreading remain, for most of them, unclear. In parallel, the 3D structures of these proteins are presented. Moreover, we proposed that TMEM proteins could be used as prognostic markers in different types of cancers and could represent potential targets for cancer treatment. A better understanding of this heterogeneous family of poorly characterized proteins thus opens perspectives for better cancer patient care.

Abstract
Aberrant ribosome biogenesis and enlarged nucleoli have long been used by pathologists as a marker of aggressive tumors. Suppression of RNA polymerase I (Pol I) transcription machinery within the nucleolus could be a direct way to trigger the nucleolar stress and to inhibit the rapid proliferation of cancer cells. Here we modified cisplatin with an analogue of the selective inhibitor of RNA polymerase I-mediated transcription BMH-21 to develop a novel platinum-based Pol I selective inhibitor. We show that this novel monofunctional platinum-based agent, P1-B1, had enhanced antitumor activity of up to 17-fold greater than the clinical drug cisplatin in cisplatin-resistant non-small cell lung cancer cells. P1-B1 also had significantly lower cytotoxicity compared to cisplatin as well as the Pol I selective inhibitor BMH-21 in MRC-5 normal lung fibroblast cells, and the selectivity index (SI) greatly increases. Mechanistic investigations revealed that P1-B1 displayed significant nucleolar accumulation, selectively inhibited Pol I transcription, and induced nucleolar stress, leading to S-phase arrest and apoptosis. Our results suggest that the effects of P1-B1 are mechanistically distinct from those of conventional platinum agents and the recently described non-classical platinum compounds and that functionalizing platinum-based agents with directly Pol I transcription inhibition properties may represent an improved modality for cancer treatment.

Abstract
Cisplatin derivatives can form various types of DNA lesions (DNA‐Pt) and trigger pleiotropic DNA damage responses. Here, we report a strategy to visualize DNA‐Pt with high resolution, taking advantage of a novel azide‐containing derivative of cisplatin we named APPA, a cellular pre‐extraction protocol and the labeling of DNA‐Pt by means of click chemistry in cells. Our investigation revealed that pretreating cells with the histone deacetylase (HDAC) inhibitor SAHA led to detectable clusters of DNA‐Pt that colocalized with the ubiquitin ligase RAD18 and the replication protein PCNA. Consistent with activation of translesion synthesis (TLS) under these conditions, SAHA and cisplatin cotreatment promoted focal accumulation of the low‐fidelity polymerase Polη that also colocalized with PCNA. Remarkably, these cotreatments synergistically triggered mono‐ubiquitination of PCNA and apoptosis in a RAD18‐dependent manner. Our data provide evidence for a role of chromatin in regulating genome targeting with cisplatin derivatives and associated cellular responses.

Abstract
Click chemistry provides fast, convenient, versatile, and reliable chemical reactions that take place between pairs of functional groups of small molecules that can be purified without chromatographic methods. Due to the fast kinetics and low or no elimination of byproducts, click chemistry is a promising approach that is rapidly gaining acceptance in drug discovery, radiochemistry, bioconjugation, and nanoscience applications. Increasing use of click chemistry in synthetic procedures or as a bioconjugation technique in diagnostic imaging is occurring because click reactions are fast, provide a quantitative yield, and produce a minimal amount of nontoxic byproducts. This review summarizes the recent application of click chemistry in magnetic resonance imaging and discusses the directions for applying novel click reactions and strategies for further improving magnetic resonance imaging performance.

Abstract
The platinum drugs, cisplatin, carboplatin, and oxaliplatin, prevail in the treatment of cancer, but new platinum agents have been very slow to enter the clinic. Recently, however, there has been a surge of activity, based on a great deal of mechanistic information, aimed at developing nonclassical platinum complexes that operate via mechanisms of action distinct from those of the approved drugs. The use of nanodelivery devices has also grown, and many different strategies have been explored to incorporate platinum warheads into nanomedicine constructs. In this Review, we discuss these efforts to create the next generation of platinum anticancer drugs. The introduction provides the reader with a brief overview of the use, development, and mechanism of action of the approved platinum drugs to provide the context in which more recent research has flourished. We then describe approaches that explore nonclassical platinum(II) complexes with trans geometry or with a monofunctional coordination mode, polynuclear platinum(II) compounds, platinum(IV) prodrugs, dual-threat agents, and photoactivatable platinum(IV) complexes. Nanoparticles designed to deliver platinum(IV) complexes will also be discussed, including carbon nanotubes, carbon nanoparticles, gold nanoparticles, quantum dots, upconversion nanoparticles, and polymeric micelles. Additional nanoformulations, including supramolecular self-assembled structures, proteins, peptides, metal-organic frameworks, and coordination polymers, will then be described. Finally, the significant clinical progress made by nanoparticle formulations of platinum(II) agents will be reviewed. We anticipate that such a synthesis of disparate research efforts will not only help to generate new drug development ideas and strategies, but also will reflect our optimism that the next generation of approved platinum cancer drugs is about to arrive.

Abstract
To enhance the functionality of Pt-based reagents, several strategies have been developed that utilize Pt compounds modified with small, reactive handles. This Account encapsulates work done by us and other groups regarding the use of Pt(II) compounds with reactive handles for subsequent elaboration with fluorophores or other functional moieties. Described strategies include the incorporation of substituents for well-known condensation or nucleophilic displacement-type reactions and their use, for example, to tether spectroscopic handles to Pt reagents for in vivo investigation. Other chief uses of displacement-type reactions have included tethering various small molecules exhibiting pharmacological activity directly to Pt, thus adding synergistic effects. Click chemistry-based ligation techniques have also been applied, primarily with azide- and alkyne-appended Pt complexes. Orthogonally reactive click chemistry reactions have proven invaluable when more traditional nucleophilic displacement reactions induce side-reactivity with the Pt center or when systematic functionalization of a larger number of Pt complexes is desired. Additionally, a diverse assortment of Pt-fluorophore conjugates have been tethered via click chemistry conjugation. In addition to providing a convenient synthetic path for diversifying Pt compounds, the use of click-capable Pt complexes has proved a powerful strategy for postbinding covalent modification and detection with fluorescent probes. This strategy bypasses undesirable influences of the fluorophore camouflaged as reactivity due to Pt that may be present when detecting preattached Pt-fluorophore conjugates. Using postbinding strategies, Pt reagent distributions in HeLa and lung carcinoma (NCI-H460) cell cultures were observed with two different azide-modified Pt compounds, a monofunctional Pt(II)-acridine type and a difunctional Pt(II)-neutral complex. In addition, cellular distribution was observed with an alkyne-appended difunctional Pt(II)-neutral complex analogous in structure to the aforementioned difunctional azide-Pt(II) reagent. In all cases, significant accumulation of Pt in the nucleolus of cells was observed, in addition to broader localization in the nucleus and cytoplasm of the cell. Using the same strategy of postbinding click modification with fluorescent probes, Pt adducts were detected and roughly quantified on rRNA and tRNA from Pt-treated Saccharomyces cerevisiae; rRNA adducts were found to be relatively long-lived and not targeted for immediate degradation. Finally, the utility and feasibility of the alkyne-appended Pt(II) compound has been further demonstrated with a turn-on fluorophore, dansyl azide, in fluorescent detection of DNA in vitro. In all, these modifications utilizing reactive handles have allowed for the diversification of new Pt reagents, as well as providing cellular localization information on the modified Pt compounds.

Abstract
DNA interstrand crosslinks (ICLs) represent physical obstacles to advancing replication forks and transcription complexes. A range of ICL-inducing agents have successfully been incorporated into cancer therapeutics. While studies have adopted UVA-activated psoralens as model ICL-inducing agents for investigating ICL repair, direct detection of the lesion has often been tempered by tagging the psoralen scaffold with a relatively large reporter group that may perturb the biological activity of the parent psoralen. Here a minimally-modified psoralen probe was prepared featuring a small alkyne handle suitable for click chemistry. The psoralen probe, designated 8-propargyloxypsoralen (8-POP), can be activated by UVA in vitro to generate ICLs that are susceptible to post-labeling with an azide-tagged fluorescent reporter via a copper-catalyzed reaction. A modified alkaline comet assay demonstrated that UVA-activated 8-POP proficiently generated ICLs in cells. Cellular 8-POP-DNA lesions were amenable to click-mediated ligation to fluorescent reporters in situ, which permitted their detection and quantitation by fluorescence microscopy and flow cytometry. Small molecule DNA repair inhibitors to 8-POP-treated cells attenuated the removal of 8-POP-DNA lesions, validating 8-POP as an appropriate probe for investigating cellular ICL repair. The post-labeling strategy applied in this study is inexpensive, rapid and highly modular in nature with the potential for multiple applications in DNA repair studies.

Abstract
Tracking of Pt(II) complexes is of crucial importance toward understanding Pt interactions with cellular biomolecules. Post-treatment fluorescent labeling of functionalized Pt(II)-based agents using the bioorthogonal Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) reaction has recently been reported as a promising approach. Here we describe an azide-functionalized Pt(II) complex, cis-[Pt(2-azidobutyl)amido-1,3-propanediamine)Cl2] (1), containing the cis geometry and difunctional reactivity of cisplatin, and present a comparative study with its previously described alkyne-functionalized congener. Single-crystal X-ray diffraction reveals a dramatic change in the solid-state arrangement with exchange of the alkyne for an azide moiety wherein 1 is dominated by a pseudo-chain of Pt-Pt dimers and antiparallel alignment of the azide substituents, in comparison with a circular arrangement supported by CH/π(C≡C) interactions in the alkyne version. In vitro studies indicate similar DNA binding and click reactivity of both congeners observed by fluorescent labeling. Interestingly, complex 1 shows in vitro enhanced click reactivity in comparison to a previously reported azide-appended Pt(II) complex. Despite their similar behavior in vitro, preliminary in cellulo HeLa studies indicate a superior imaging potential of azide-functionalized 1. Post-treatment fluorescent labeling of 1 observed by confocal fluorescence microscopy shows nuclear and intense nucleolar localization. These results demonstrate the potential of 1 in different cell line localization studies and for future isolation and purification of Pt-bound targets.

Abstract
The cellular recognition and processing of monofunctional-intercalative DNA adducts formed by [PtCl(en)(L)](NO3)2 (P1-A1; en = ethane-1,2-diamine; L = N-[2-(acridin-9-ylamino)ethyl]-N-methylpropionamidine, acridinium cation), a cytotoxic hybrid agent with potent anticancer activity, was studied. Excision of these adducts and subsequent DNA repair synthesis were monitored in plasmids modified with platinum using incubations with mammalian cell-free extract. On the basis of the levels of [α-(32)P]-dCTP incorporation, P1-A1-DNA adducts were rapidly repaired with a rate approximately 8 times faster (t1/2 ≈ 18 min at 30 °C) than the adducts (cross-links) formed by the drug cisplatin. Cellular responses to P1-A1 and cisplatin were also studied in NCI-H460 lung cancer cells using immunocytochemistry in conjunction with confocal fluorescence microscopy. At the same dose, P1-A1, but not cisplatin, elicited a distinct requirement for DNA double-strand break repair and stalled replication fork repair, which caused nuclear fluorescent staining related to high levels of MUS81, a specialized repair endonuclease, and phosphorylated histone protein γ-H2AX. The results confirm previous observations in yeast-based chemical genomics assays. γ-H2AX fluorescence is observed as a large number of discrete foci signaling DNA double-strand breaks, pan-nuclear preapoptotic staining, and unique circularly shaped staining around the nucleoli and nuclear rim. DNA cleavage assays indicate that P1-A1 does not act as a typical topoisomerase poison, suggesting the high level of DNA double-strand breaks in cells is more likely a result of topoisomerase-independent replication fork collapse. Overall, the cellular response to platinum-acridines shares striking similarities with that reported for DNA adduct-forming derivatives of the drug doxorubicin. The results of this study are discussed in light of the cellular mechanism of action of platinum-acridines and their ability to overcome resistance to cisplatin.

Abstract
The platinum drugs cisplatin, carboplatin, and oxaliplatin are highly utilized in the clinic and as a consequence have been extensively studied in the laboratory setting, sometimes by generating fluorophore-tagged analogs. Here, we synthesized two Pt(II) complexes containing ethane-1,2-diamine ligands linked to a BODIPY fluorophore, and compared their biological activity with previously reported Pt(II) complexes conjugated to carboxyfluorescein and carboxyfluorescein diacetate. The cytotoxicity and DNA damage capacity of Pt-fluorophore complexes was compared to cisplatin, and the Pt-BODIPY complexes were found to be more cytotoxic with reduced cytotoxicity in cisplatin-resistant cells. Microscopy revealed a predominately cytosolic localization, with nuclear distribution at higher concentrations. Spheroids grown from parent and resistant cells revealed penetration of Pt-BODIPY into spheroids, and retention of the cisplatin-resistant spheroid phenotype. While most activity profiles were retained for the Pt-BODIPY complexes, accumulation in resistant cells was only slightly affected, suggesting that some aspects of Pt-fluorophore cellular pharmacology deviate from cisplatin.
