Abstract
The quest for novel, physiologically active imidazoles remains an exciting topic of research among medicinal chemists. The imidazole ring is a five-membered aromatic heterocycle that is found in both natural and synthesized compounds. Multiple anticancer drug classes are currently available on the market, but concerns including toxicity, limited efficacy and solubility have lowered the overall therapeutic index. Therefore, the hunt for new potential chemotherapeutic agents persists. The development of imidazole as a reliable and safer alternative to anticancer treatment is generating much attention among experts. Tubulin or microtubule polymerization inhibition and changes in the structure and function of DNA, VEGF, topoisomerase, kinases, histone deacetylases and certain other proteins that affect gene expression are among the putative targets.

Abstract
Tubulin inhibitors can interfere with normal cell mitosis and inhibit cell proliferation through interfering with the normal structure and function of microtubules, forming spindle filaments. Indole, as a privileged pharmacological skeleton, has been widely used in anti-cancer inhibitors. A variety of alkaloids containing an indole core obtained from natural sources have been proven to inhibit tubulin polymerization, and an ever-increasing number of synthetic indole-based tubulin inhibitors have been reported. Among these, several kinds of indole-based derivatives, such as TMP analogues, aroylindoles, arylthioindoles, fused indole, carbazoles, azacarbolines, alkaloid nortopsentin analogues and bis-indole derivatives, have shown good inhibition activities towards tubulin polymerization. The binding modes and SARs investigations of synthetic indole derivatives, along with a brief mechanism on their anti-tubulin activity, are presented in this review.

Abstract
Tubulin inhibitors are conjugates that interfere with the dynamic equilibrium of the polymerization and depolymerization of microtubules. Among all the reported conjugates, indole moiety is one of the most significant classes for the development of new drug candidates for cancer therapy. Due to their presence in a wide range of natural as well as synthetic antitubulin agents, indole has become a versatile scaffold in research, and various synthetic and semisynthetic indole-based antitubulin agents have been identified and reported. The present article focuses on the reported indole-based tubulin inhibitors of synthetic origin from last the decade. Synthesis, structure-activity relationships and biological activities of synthetic indole derivatives along with brief updates on their antitubulin activity are presented.

Abstract
In previous research, a series of cytotoxic anticancer analogues related to 2-acylamino-1,4-naphthoquinone derivatives has been demonstrated. As microtubule plays an important role in many essential cellular processes such as mitosis, tubulin is an important target of anticancer drug. This study performed molecular docking simulation, pharmacophore model, comparative force field analysis model and comparative similarity indices analysis model to investigate the relationship between inhibitory activities and the properties of compounds, in order to further progress the development of cytotoxic anticancer analogues. These compounds have common H-bond interactions with key residues Lys254 and Lys352, but compounds with large R2 substituent have different docking poses than compounds with small R2 substituent. Some of derivatives such as compound 18 formed the H-bonds with residue Lys254 using the oxygen atoms in R1 substituent and formed π-cation interactions with residue Lys352 using phenyl moiety of 1,4-naphthoquinone. The R1 substituent of these compounds preferred to have disfavoured hydrophobic fields and favourable space towards the direction of residue Asn258, while the R2 substituent of these compounds preferred to have about 2-3 carbon chain length hydrophobic substituent towards the direction of residues Ala316 and Lys352. These results offer some beneficial advices for further study in anticancer drug development process.

Abstract
The new derivatives based on (Z)-3-(arylamino)-1-(3-phenylimidazo[1,5-a]pyridin-1-yl)prop-2-en-1-one scaffold was synthesized and evaluated for their in vitro cytotoxic potential against a panel of cancer cell lines, viz., A549 (human lung cancer), HCT-116 (human colorectal cancer), B16F10 (murine melanoma cancer), BT-474 (human breast cancer), and MDA-MB-231 (human triple-negative breast cancer). Among them, many of the synthesized compounds exhibited promising cytotoxic potential against the panel of tested cancer cell lines with IC50 <30 µM. Based on the preliminary screening results, the structure-activity relationship (SAR) of the compounds was established. Among the synthesized compounds, 15i displayed a potential anti-proliferative activity against HCT-116 cancer cell line with an IC50 value of 1.21 ± 0.14 µM. Flow cytometric analysis revealed that compound 15i arrested the G0/G1 phase of the cell cycle. Moreover, increased reactive oxygen species (ROS) generation, clonogenic assay, acridine orange staining, DAPI nuclear staining, measurement of mitochondrial membrane potential (ΔΨm), and annexin V-FITC assays revealed that compound 15i promoted cell death through apoptosis.

Abstract
A series of unique dispiro analogues containing an oxindole pyrrolidine 8-nitroquinolone hybrid has been obtained through a one-pot three-component 1,3-dipolar cycloaddition of azomethine ylides generated in situ from the condensation of isatins and benzylamine with (E)-3-arylidene-2,3-dihydro-8-nitro-4-quinolones. The structures of the newly synthesized compounds were characterized by using different spectroscopic techniques and by X-ray diffraction studies of their regio- and stereochemistry. All the synthesized compounds were screened for in vitro cytotoxic activity against the human cervical cancer cell line HeLa. The compounds have exhibited potent inhibition against human cervical cancer cells and insignificant toxicity to normal cells. The compounds 6d, 6a, 6h, 6b, and 6e induced apoptosis of HeLa cells, through ROS influx. The expression levels of proteins involved in the mitochondrion-related pathways were detected, and Western blot analysis showed that apoptosis occurred via activation of caspase-3.
