Abstract
In this article, a new series of 2-((3,5-disubstituted-2-thioxo-imidazol-1-yl)imino)acenaphthylen-1(2H)-ones were synthesized. Imidazole-2-thione with acenaphthylen-one gave a hybrid scaffold that integrated key structural elements essential for DNA damage via direct DNA intercalation and inhibition of the topoisomerase II enzyme. All the synthesized compounds were screened to detect their DNA damage using a terbium fluorescent probe. Results demonstrated that 4-phenyl-imidazoles 5b and 5e in addition to 4-(4-chlorophenyl)imidazoles 5h and 5j would induce detectable potent damage in ctDNA. The four most potent compounds as DNA intercalators were further evaluated for their antiproliferative activity against HepG2, MCF-7 and HCT-116 utilizing the MTT assay. The highest anticancer activity was recorded with compounds 5b and 5h against the breast cancer cell line MCF-7 which were 1.5- and 3- folds more active than doxorubicin, respectively. Therefore, imidazole-2-thione tethered acenaphthylenone derivatives can be considered as promising scaffold for the development of effective dual DNA intercalators and topoisomerase II inhibitors.

Abstract
A series of novel dehydroabietic acid derivatives containing both 1,2,3-triazole and oxazolidinone 4a-4t have been synthesized and their antiproliferative activity in vitro against HeLa, HepG2, MGC-803 and T-24 cell lines evaluated. Most of them displayed cell proliferation inhibition on four tested human malignant tumour cell lines to some degree. Among them, compound 4p exhibited promising cytotoxicity with IC50 values ranging from 3.18 to 25.31 μM and weak cytotoxicity toward normal cells. The mechanism of action of 4p was then studied using flow cytometry, Hoechst 33258 staining, ROS generation assay, and JC-1 mitochondrial membrane potential staining, which illustrated that compound 4p induced apoptosis, arrested mitotic process at the G1 phase of the cell cycle, reduced the mitochondrial membrane potential, and increased intracellular ROS levels. In summary, the introduction of an oxazolidinone group via a "1,2,3-triazole" linker significantly improved the antitumor activity of dehydroabietic acid, and deserves to be further investigated.

Abstract
Cancer stands as one of the deadliest diseases, ranking second in terms of its global impact. Despite the presence of numerous compelling theories concerning its origins, none have succeeded in fully elucidating the intricate nature of this ailment. Among the prevailing concerns in today's world, breast cancer proliferation remains a significant issue, particularly affecting females. The abnormal proliferation of the PI3K pathway emerges as a prominent driver of breast cancer, underscoring its role in cellular survival and proliferation. Consequently, targeting this pathway has emerged as a leading strategy in breast cancer therapeutics. Within this context, the present article explores the current landscape of anti-tumour drug development, focusing on structural activity relationships (SAR) in PI3K targeting breast cancer treatment. Notably, certain moieties like triazines, pyrimidine, quinazoline, quinoline, and pyridoxine have been explored as potential PI3K inhibitors for combating breast cancer. Various heterocyclic small molecules are undergoing clinical trials, such as Alpelisib, the first orally available FDA-approved drug targeting PI3K; others include buparlisib, pictilisib, and taselisib, which inhibit class I PI3K. These drugs are used for the treatment of breast cancer but still have various side effects with their high cost. Therefore, the primary goal of this review is to include all current advances in the development of anticancer medicines that target PI3K over-activation in the treatment of breast cancer.

Abstract
Blocking the PI3K/Akt pathway has been widely recognized as an attractive cancer therapeutic strategy because of its crucial role in cell growth and survival. This study presents the synthesis of 24 new 5-Methoxy-6-substituted-1H-benzimidazole derivatives (4a-4x) and the evaluation of their anti-proliferative activities against A549, Siha, MCF-7, HepG2, PC3, and HCT-116 tumor cell lines through MTT assay. Compound 4w exhibited superior anti-tumor activity against the A549 cells with IC50 values of 1.55 ± 0.18 μM, and better than the BKM120 (IC50 = 9.75 ± 1.25 µM). Further studies indicated that 4w could induce G0/G1 phase arrest, cell apoptosis, and down-regulate expression of p-PI3K and p-Akt. These results indicate that 4w could be served as a lead compound of PI3K inhibitor for the treatment of human lung cancers.

Abstract
Nepetaefolin F (5), an abietane diterpenoid, showed significant inhibitory activity against human cancer cells in vitro with an IC50 value of 6.3 μM. The syntheses of nepetaefolin F and its analogues are presented herein. The cytotoxicity against various cancer cell lines was evaluated; notably, the cyclopropanecarboxylate ester 42 displayed significant antitumor activity against MGC 803 cells with an IC50 value of 20.9 μM. Further studies revealed that 42 could upregulate the expression of p62, microtubule-associated protein 1 light-chain 3 β (LC3 B-I), cleaved caspase-3, and cleaved caspase-9 and downregulate the expression of Beclin-1 and LC3B-II. Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis showed that 42 could modulate multiple signaling pathways, especially for peroxisome proliferator-activated receptor (PPAR) and AMP-activated protein kinase (AMPK), which are closely related to autophagy. These results suggested that compound 42 is a promising lead by inhibiting cell proliferation and autophagy, as inducing cell apoptosis in MGC 803 cells.

Abstract
Abstract
Cancer, one of the key health problems globally, is a group of related diseases that share a number of characteristics primarily the uncontrolled growth and invasive to surrounding tissues. Chemotherapy is one of the ways for the treatment of cancer which uses one or more anticancer agents as per chemotherapy regimen. Limitations of most anticancer drugs due to a variety of reasons such as serious side effects, drug resistance, lack of sensitivity and efficacy etc. generate the necessity towards the designing of novel anticancer lead molecules. In this regard, the synthesis of biologically active heterocyclic molecules is an appealing research area. Among heterocyclic compounds, nitrogen containing heterocyclic molecules has fascinated tremendous consideration due to broad range of pharmaceutical activity. Imidazoles, extensively present in natural products as well as synthetic molecules, have two nitrogen atoms, and are five membered heterocyclic rings. Because of their countless physiological and pharmacological characteristics, medicinal chemists are enthused to design and synthesize new imidazole derivatives with improved pharmacodynamic and pharmacokinetic properties. The aim of this present chapter is to discuss the synthesis, chemistry, pharmacological activity, and scope of imidazole-based molecules in anticancer drug development. Finally, we have discussed the current challenges and future perspectives of imidazole-based derivatives in anticancer drug development.

Abstract
Nitrogen-containing heterocyclic rings are common structural components of marketed drugs. Among these heterocycles, imidazole/fused imidazole rings are present in a wide range of bioactive compounds. The unique properties of such structures, including high polarity and the ability to participate in hydrogen bonding and coordination chemistry, allow them to interact with a wide range of biomolecules, and imidazole-/fused imidazole-containing compounds are reported to have a broad spectrum of biological activities. This review summarizes recent reports of imidazole/fused imidazole derivatives as anticancer agents appearing in the peer-reviewed literature from 2018 through 2020. Such molecules have been shown to modulate various targets, including microtubules, tyrosine and serine-threonine kinases, histone deacetylases, p53-Murine Double Minute 2 (MDM2) protein, poly (ADP-ribose) polymerase (PARP), G-quadraplexes, and other targets. Imidazole-containing compounds that display anticancer activity by unknown/undefined mechanisms are also described, as well as key features of structure-activity relationships. This review is intended to provide an overview of recent advances in imidazole-based anticancer drug discovery and development, as well as inspire the design and synthesis of new anticancer molecules.

Abstract
Cancer is characterized by an uncontrolled proliferation of cells, dedifferentiation,
invasiveness and metastasis. Endothelial growth factor (eGF), insulin-like growth factor
(IGF), platelet-derived growth factor (PDGF), Fibroblast growth factor (FGF), Vascular endothelial
growth factor (VEGF), checkpoint kinase 1 & 2 ( Chk1 & Chk2), aurora kinases,
topoisomerases, histone deacetylators (HDAC), poly(ADP-Ribose)polymerase (PARP), farnesyl
transferases, RAS-MAPK pathway and PI3K-Akt-mTOR pathway, are some of the
prominent mediators implicated in the proliferation of tumor cells. Huge artillery of natural
and synthetic compounds as anticancer, which act by inhibiting one or more of the enzymes
and/or pathways responsible for the progression of tumor cells, is reported in the literature.
The major limitations of anticancer agents used in clinics as well as of those under development
in literature are normal cell toxicity and other side effects due to lack of specificity.
Hence, medicinal chemists across the globe have been working for decades to develop potent and safe anticancer
agents from natural sources as well as from different classes of heterocycles. Benzimidazole is one of the most important
and explored heteronucelus because of their versatility in biological actions as well as synthetic applications
in medicinal chemistry. The structural similarity of amino derivatives of benzimidazole with purines makes it a fascinating
nucleus for the development of anticancer, antimicrobial and anti-HIV agents. This review article is an attempt
to critically analyze various reports on benzimidazole derivatives acting on different targets to act as anticancer so as
to understand the structural requirements around benzimidazole nucleus for each target and enable medicinal chemists
to promote rational development of antitumor agents.

Abstract
A novel series of N-1 arylidene amino imidazole-2-thiones were synthesized, identified using IR, 1H-NMR, and 13C-NMR spectral data. Cytotoxic effect of the prepared compounds was carried out utilizing three cancer cell lines; MCF-7 breast cancer, HepG2 liver cancer, and HCT-116 colon cancer cell lines. Imidazole derivative 5 was the most potent of all against three cell lines. DNA flow cytometric analysis showed that, imidazoles 4d and 5 exhibit pre-G1 apoptosis and cell cycle arrest at G2/M phase. The results of the VEGFR-2 and B-Raf kinase inhibition assay revealed that compounds 4d and 5 displayed good inhibitory activity compared with reference drug erlotinib.
