Abstract
Thermally activated delayed fluorescence (TADF) material has attracted great attention as a promising metal-free organic light-emitting diode material with a high theoretical efficiency. To accelerate the discovery of novel TADF materials, computer-aided material design strategies have been developed. However, they have clear limitations due to the accessibility of only a few computationally tractable properties. Here, we propose TADF-likeness, a quantitative score to evaluate the TADF potential of molecules based on a data-driven concept of chemical similarity to existing TADF molecules. We used a deep autoencoder to characterize the common features of existing TADF molecules with common chemical descriptors. The score was highly correlated with the four essential electronic properties of TADF molecules and had a high success rate in large-scale virtual screening of millions of molecules to identify promising candidates at almost no cost, validating its feasibility for accelerating TADF discovery. The concept of TADF-likeness can be extended to other fields of materials discovery.

Yakkala PA, Penumallu NR, Shafi S, Kamal A. Prospects of Topoisomerase Inhibitors as Promising Anti-Cancer Agents. Pharmaceuticals (Basel) 2023; 16:1456. [PMID: 37895927 PMCID: PMC10609717 DOI: 10.3390/ph16101456] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2023] [Revised: 10/08/2023] [Accepted: 10/11/2023] [Indexed: 10/29/2023] Open
Abstract
Topoisomerases are very important enzymes that regulate DNA topology and are vital for biological actions like DNA replication, transcription, and repair. The emergence and spread of cancer has been intimately associated with topoisomerase dysregulation. Topoisomerase inhibitors have consequently become potential anti-cancer medications because of their ability to obstruct the normal function of these enzymes, which leads to DNA damage and subsequently causes cell death. This review emphasizes the importance of topoisomerase inhibitors as marketed, clinical and preclinical anti-cancer medications. In the present review, various types of topoisomerase inhibitors and their mechanisms of action have been discussed. Topoisomerase I inhibitors, which include irinotecan and topotecan, are agents that interact with the DNA-topoisomerase I complex and avert resealing of the DNA. The accretion of DNA breaks leads to the inhibition of DNA replication and cell death. On the other hand, topoisomerase II inhibitors like etoposide and teniposide, function by cleaving the DNA-topoisomerase II complex thereby effectively impeding the release of double-strand DNA breaks. Moreover, the recent advances in exploring the therapeutic efficacy, toxicity, and MDR (multidrug resistance) issues of new topoisomerase inhibitors have been reviewed in the present review.

Abstract
Rhenium complexes have been observed experimentally to exhibit good inhibitory activity against malignant cells. Hence, our motivation is to explore this activity from a theoretical perspective. In the present study, density functional theory (DFT) and in silico molecular docking approaches were utilized to unravel the unique properties of metal-based rhenium tricarbonyl complexes as effective anticancer drugs. All DFT calculations and geometric optimizations were conducted using the well-established hybrid functional B3LYP-GD(BJ)/Gen/6-311++G(d,p)/LanL2DZ computational method. The FT-IR spectroscopic characterization of the complexes: fac-[Re(Pico)(CO)3(Pz)] (R1), fac-[Re(Pico)(CO)3(Py)] (R2), fac-[Re(Dfpc)(CO)3(H2O)] (R3), fac-[Re(Dfpc)(CO)3(Pz)] (R4), fac-[Re(Dfpc)(CO)3(Py)] (R5), fac-[Re(Tfpc)(CO)3(H2O)] (R6), fac-[Re(Tfpc)(CO)3(Py)] (R7), and fac-[Re(Tfpc)(CO)3(Im)] (R8) was explored. To gain insights into the electronic structural properties, bioactivity, and stability of these complexes, the highest occupied molecular orbital-lowest unoccupied molecular orbital analysis, binding energy, and topological analysis based on quantum theory of atoms-in-molecules were considered. The anticancer activities of the complexes were measured via in silico molecular docking against human BCL-2 protein (IG5M) and proapoptotic (agonist) BAX 1 protein (450O). The results showed that the studied complexes exhibited good binding affinity (-3.25 to -10.16 kcal/mol) and could cause significant disruption of the normal physiological functions of the studied proteins. The results of DFT calculations also showed that the studied complexes exhibited good stability and are suitable candidates for the development of anticancer agents.

Abstract
Human DNA topoisomerase II alpha (hTopIIα) is a classic chemotherapeutic drug target. The existing hTopIIα poisons cause numerous side effects such as the development of cardiotoxicity, secondary malignancies, and multidrug resistance. The use of catalytic inhibitors targeting the ATP-binding cavity of the enzyme is considered a safer alternative due to the less deleterious mechanism of action. Hence, in this study, we carried out high throughput structure-based virtual screening of the NPASS natural product database against the ATPase domain of hTopIIα and identified the five best ligand hits. This was followed by comprehensive validation through molecular dynamics simulations, binding free energy calculation and ADMET analysis. On stringent multilevel prioritization, we identified promising natural product catalytic inhibitors that showed high binding affinity and stability within the ligand-binding cavity and may serve as ideal hits for anticancer drug development.Communicated by Ramaswamy H.

Abstract
The topoisomerases (TOPO) play indispensable roles in DNA metabolism, by regulating the topological state of DNA. Topoisomerase I and II are the well-established drug-targets for the development of anticancer agents and antibiotics. These drugs-targeting enzymes have been used to establish the relationship between drug-stimulated DNA cleavable complex formation and cytotoxicity. Some anticancer drugs (such as camptothecin, anthracyclines, mitoxantrone) are also widely used as Topo I and Topo II inhibitors, but the poor water solubility, myeloma suppression, dose-dependent cardiotoxicity, and multidrug resistance (MDR) limited their prolong use as therapeutics. Also, most of these agents displayed selective inhibition only against Topo I or II. In recent years, researchers focus on the design and synthesis of the dual Topo I and II inhibitors, or the discovery of the dual Topo I and II inhibitors from natural products. Shikonin (a natural compound with anthraquinone skeleton, isolated from the roots of Lithospermum erythrorhizon) has drawn much attention due to its wide spectrum of anticancer activities, especially due to its dual Topo inhibitive performance, and without the adverse side effects, and different kinds of shikonin derivatives have been synthesized as TOPO inhibitors for the development of anticancer agents. In this review, the progress of the shikonin and its derivatives together with their anticancer activities, anticancer mechanism, and their structure-activity relationship (SAR) was comprehensively summarized by searching the CNKI, PubMed, Web of Science, Scopus, and Google Scholar databases.

Abstract
A strategy of "Nature-to-new" with iterative scaffold-hopping was considered for investigation of privileged ring/functional motif-elaborated analogs of natural aurones. An organocatalyzed umpolung chemistry based method was established for molecular-diversity feasible synthesis of title class of chemotypes i.e. (Z)-2-Arylideneimidazo[1,2-a]pyridinones and (Z)-2-Arylidenebenzo[d]imidazo[2,1-b]thiazol-3-ones. Various biophysical experiments indicated their important biological properties. The analogs showed characteristic anticancer activities with efficiency more than an anticancer drug. The compounds induced apoptosis with arrest in the S phase of the cell cycle regulation. The compounds' significant effect in up/down-regulation of various apoptotic proteins, an apoptosis cascade, and the inhibition of topoisomerases-mediated DNA relaxation process was identified. The analysis of the structure-activity relationship, interference with biological events and the drug-likeness physicochemical properties of the compounds in the acceptable window indicated distinctive medicinal molecule-to-properties of the investigated chemotypes.

Abstract
Several anticancer agents have been developed and innovative approaches have been made toward cancer type-specific medicines for cancer treatment. As a continuous effort to develop potential chemotherapeutic agents, a novel series of 2,4-diphenyl-5,6-dihydrobenzo(h)quinolin-8-amines containing amino groups, hydroxyphenyl and fluorine functionalities were designed and synthesized. The compounds were evaluated for topo IIα inhibitory and cytotoxicity against HCT15, and HeLa human cancer cell lines. Among synthesized thirty compounds, the majority exhibited strong topo IIα inhibition and anti-proliferation against HCT15 colorectal adenocarcinoma cell line. The structure-activity relationship study revealed that compounds with -CF3 and -OCF3 substituents at 4- position and 3' or 4'-hydroxyphenyl at 2-position attached to the central pyridine ring displayed potent topo IIα and anti-proliferative activity in colorectal and cervix cancer cell line. In vitro studies provided the evidence that compounds 16, 19, 22, and 28 possess excellent topo IIα inhibition and antiproliferative activity. For a better understanding, topo IIα cleavage complex, EtBr displacement, KI quenching assays and molecular docking of compound 19 was performed and the results revealed the mode of action as a DNA intercalative topo IIα poison inhibitor. The results obtained from this study provide insight into the DNA binding mechanism of 2,4-diphenyl-5,6-dihydrobenzo(h)quinolin-8-amines and alteration in topo IIα inhibitory and antiproliferative activity with modifications in the rigid structure.

Abstract
Abstract
Various computational approaches have received ever-growing role in the design of potential inhibitors of the topoisomerase 2 (TOP2A) for cancer treatment. TOP2A plays a key role in the deoxyribonucleic acid (DNA) replication before cell division and thus facilitates the growth of cells. This TOP2A function can be suppressed by targeting it with potential inhibitors in cancer cells to terminate the uncontrolled cell division. Among potential inhibitors, cryptolepine has higher selectivity along with the ability to intercalate into DNA, effectively blocking TOP2A and ceasing cell division in cancer cells. However, this compound has drawbacks of being nonspecific and possessing relatively low affinity. Therefore, a combinatorial library of 31,114 cryptolepine derivatives was designed and virtually screened by molecular docking to predict the molecular interactions between the cryptolepine derivatives and TOP2A using cryptolepine as a standard. All the binding poses of cryptolepine derivatives for TOP2A were investigated to calculate binding energy. The compounds with the database numbers 8618, 907, 147, 16755, and 8186 scored the highest binding energies, −9.88, −9.76, −9.75, −9.73, and −9.72 kcal/mol, respectively, and the highest binding affinities while the cryptolepine binding energy is −6.09 kcal/mol. The strong binding interactions of these derivatives show that they can be used as potent TOP2A inhibitors and act as more effective anticancer agents than cryptolepine itself. The interactions of these derivatives with different amino acid residues were also observed and analyzed. A comprehensive understanding of the interactions of the proposed derivatives with TOP2A helped for searching more novel and potent drug-like molecules for anticancer therapy. This computational study suggests useful references to understand inhibition mechanisms that will help in the further modifications of TOP2A inhibitors. Moreover, the DFT study of the derivatives with the highest binding energies was performed, helping to further understand the binding affinities of these compounds.

Abstract
Long-term survivors of glioblastoma multiforme (GBM) are at high risk of developing second primary neoplasms, including leukemia. For these patients, the use of classic tyrosine kinase inhibitors (TKIs), such as imatinib mesylate, is strongly discouraged, since this treatment causes a tremendous increase of tumor and stem cell migration and invasion. We aimed to develop agents useful for the treatment of patients with GBM and chronic myeloid leukemia (CML) using an alternative mechanism of action from the TKIs, specifically based on the inhibition of tubulin polymerization. Compounds 7 and 25, as planned, not only inhibited tubulin polymerization, but also inhibited the proliferation of both GMB and CML cells, including those expressing the T315I mutation, at nanomolar concentrations. In in vivo experiments in BALB/cnu/nu mice injected subcutaneously with U87MG cells, in vivo, 7 significantly inhibited GBM cancer cell proliferation, in vivo tumorigenesis, and tumor growth, tumorigenesis and angiogenesis. Compound 7 was found to block human topoisomerase II (hTopoII) selectively and completely, at a concentration of 100 μM.

Abstract
The objective of this study was to discover potential topoisomerase (topo) targeting anticancer agents. Novel series of hydroxylated and halogenated(-F, -Cl, and -CF3) 2,4-diaryl benzofuro[3,2-b]pyridin-7-ols were systematically designed and synthesized by faster, economic, and environmentally friendly l-proline catalyzed and microwave-assisted one pot reaction method. The synthesized compounds were assessed for topo I and IIα inhibitory and anti-proliferative activities. The in vitroevaluation displayed that most of the compounds have selective topo IIα inhibitoryactivity as well as selectivity towards T47D human cancer cell line. Structure-activity relationship study suggested that the introduction of additional hydroxyl functionality at 7-positon of benzofuro[3,2-b]pyridine skeleton is crucial for selective topo IIα inhibitory activity. Placement of phenolic moiety on the 4-position of the tricyclic system imparts better topo IIα inhibitory and anti-proliferative activity.
