Background: Breast cancer (BC) is among the leading causes of death among women worldwide. Medical interest has focused on quinazolinone derivatives approved and utilized in antitumor medications. Objective: Novel quinazolinone-based oxobutanonitrile derivatives were designed, synthesized, and screened for in vitro anti-BC activity. Methods: The antiproliferative activities were determined using MTT assay against MCF-7 and MDA-MB-231 cell lines. EGFR, ARO, and caspase-9 enzymes were selected to explore the mechanism of action of the most potent compounds. Results: Tested compounds showed better EGFRIs than ARIs. In addition, significant overexpression in caspase-9 level in treated MCF-7 breast cell line samples was observed with the most active compounds. The thienyl derivative 5 induced the greatest activation in caspase-9 level in treated MCF-7 breast cancer samples. The o-tolylhydrazone 3b, exhibiting promising ARO inhibition and weak EGFR inhibition, produced a noticeable high overexpression of caspase-9 and showed pre-G1 apoptosis and cell cycle arrest at G2/M phase for MCF-7 cells and at S-phase for MDA-MB-231 cells. Docking results revealed that 3b, elicited binding affinities to ARO comparable to those of letrozole. Conclusion: The obtained results support the therapeutic importance of some of these compounds as anti-BC agents in light of the simple methodology used for their synthesis. Their design offered a way for the optimization and development of apoptotic quinazolinone-based ARO and EGFR inhibitors.

Breast cancer is still considered a high-incidence disease, and numerous are the research efforts for the development of new useful and effective therapies. Among anticancer drugs, carbazole compounds are largely studied for their anticancer properties and their ability to interfere with specific targets, such as microtubule components. The latter are involved in vital cellular functions, and the perturbation of their dynamics leads to cell cycle arrest and subsequent apoptosis. In this context, we report the anticancer activity of a series of carbazole analogues 1–8. Among them, 2-nitrocarbazole 1 exhibited the best cytotoxic profile, showing good anticancer activity against two breast cancer cell lines, namely MCF-7 and MDA-MB-231, with IC50 values of 7 ± 1.0 and 11.6 ± 0.8 μM, respectively. Furthermore, compound 1 did not interfere with the growth of the normal cell line MCF-10A, contrarily to Ellipticine, a well-known carbazole derivative used as a reference molecule. Finally, in vitro immunofluorescence analysis and in silico studies allowed us to demonstrate the ability of compound 1 to interfere with tubulin organization, similarly to vinblastine: a feature that results in triggering MCF-7 cell death by apoptosis, as demonstrated using a TUNEL assay.

Abstract A progression of novel thiadiazoline spiro quinoline derivatives were synthesized from potent thiadiazoline spiro quinoline derivatives . The synthesized compounds portrayed by different spectroscopic studies and single X-ray crystallographic studies. The compounds were assessed for in vitro anticancer properties towards MCF-7 and HeLa cells. The compounds showed superior inhibition action MCF-7 malignant growth cells. Amongst, the compound 4a showed significant inhibition activity, the cell death mechanism was evaluated by fluorescent staining, and flow cytometry, RT-PCR, and western blot analyses. The in vitro anticancer results revealed that the compound 4a induced apoptosis by inhibition of estrogen receptor alpha (ERα) and G2/M phase cell cycle arrest. The binding affinity of the compounds with ERα and pharmacokinetic properties were confirmed by molecular docking studies.

A series of 2-arylidene-N-(quinolin-6-yl)hydrazine-1-carboxamides 5a–5o were synthesized and characterized. The synthesized compounds (5a–5o) were screened in vitro against three breast cancer cell lines: SKBR3, MDA-MB-231, and MCF-7 cancer cell lines by the MTT assay. According to MTT results, compounds 5k and 5l showed better antiproliferative activities over MCF-7 cell lines with IC50 values of 8.50 and 12.51 μM. Colony formation assay indicated 5k/5l treatment obviously inhibited the growth of MCF-7 cells and 5k/5l-induced cell cycle was arrested in the G2-M phase. Moreover, 5k/5l significantly increased the level of cleaved PARP and induced the apoptosis in MCF-7 cells. In addition, compared to Hela cells, MCF-7 cells were more sensitive to 5k/5l treatment.

Abstract Keeping in view the emerging need of potent and safer anti-breast cancer agents as well as pharmacological attributes of isatin, quinoline and morpholine derivatives, novel hydrazone linked morpholinated isatin-quinoline hybrids has been designed, synthesized and evaluated as anti-breast cancer agents. Synthesized hybrid compounds were preliminary screened against two breast cancer cell lines (MCF-7 and MDA-MB-231). Almost all synthetics showed potent inhibitory potential against hormone positive MCF-7 cells while inactive against hormone negative MDA-MB-231 cells. Potent compounds were further evaluated against L929 (noncancerous skin fibroblast) cell line and found highly selective for MCF-7 cells over L929 cells. Cell cycle analysis confirmed that most potent compound AS-4 (MCF-7: GI50 = 4.36 µM) cause mitotic arrest at G2/M-phase. Due to higher selectivity toward estrogen receptor alpha (ERα) dependent MCF-7 cells various binding interactions of AS-4 with ERα are also streamlined, suggesting the capability of AS-4 in completely blocking ERα. Overall study suggest that, AS-4 can act as a potential lead for further development of potent and safer anti-breast cancer agents.

Diverse indoles and bis-indoles extracted from marine sources have been identified as promising anticancer leads. Herein, we designed and synthesized novel bis-indole series 7a–f and 9a–h as Topsentin and Nortopsentin analogs. Our design is based on replacing the heterocyclic spacer in the natural leads by a more flexible hydrazide linker while sparing the two peripheral indole rings. All the synthesized bis-indoles were examined for their antiproliferative action against human breast cancer (MCF-7 and MDA-MB-231) cell lines. The most potent congeners 7e and 9a against MCF-7 cells (IC50 = 0.44 ± 0.01 and 1.28 ± 0.04 μM, respectively) induced apoptosis in MCF-7 cells (23.7-, and 16.8-fold increase in the total apoptosis percentage) as evident by the externalization of plasma membrane phosphatidylserine detected by Annexin V-FITC/PI assay. This evidence was supported by the Bax/Bcl-2 ratio augmentation (18.65- and 11.1-fold compared to control) with a concomitant increase in the level of caspase-3 (11.7- and 9.5-fold) and p53 (15.4- and 11.75-fold). Both compounds arrested the cell cycle mainly in the G2/M phase. Furthermore, 7e and 9a displayed good selectivity toward tumor cells (S.I. = 38.7 and 18.3), upon testing of their cytotoxicity toward non-tumorigenic breast MCF-10A cells. Finally, compounds 7a, 7b, 7d, 7e, and 9a were examined for their plausible CDK2 inhibitory action. The obtained results (% inhibition range: 16%–58%) unveiled incompetence of the target bis-indoles to inhibit CDK2 significantly. Collectively, these results suggested that herein reported bis-indoles are good lead compounds for further optimization and development as potential efficient anti-breast cancer drugs.
