A series of novel quinazolinone derivatives (2–13) was synthesized and examined for their cytotoxicity to HepG2, MCF-7, and Caco-2 in an MTT assay. Among these derivatives, compounds 4 and 9 exhibited significant cytotoxic activity against Caco-2, HepG2, and MCF-7 cancer cells. Compound 4 had more significant inhibitory effects than compound 9 on Caco-2, HepG2, and MCF-7 cell lines, with IC50 values of 23.31 ± 0.09, 53.29 ± 0.25, and 72.22 ± 0.14µM, respectively. The AKT pathway is one of human cancer’s most often deregulated signals. AKT is also overexpressed in human cancers such as glioma, lung, breast, ovarian, gastric, and pancreas. A molecular docking study was performed to analyze the inhibitory action of newly synthetic quinazolinone derivatives against Homo sapiens AKT1 protein. Molecular docking simulations were found to be in accordance with in vitro studies, and hence supported the biological activity. The results suggested that compounds 4 and 9 could be used as drug candidates for cancer therapy via its potential inhibition of AKT1 as described by docking study.

Background and Purpose: Gambogic acid (GA), a promising anti-cancer agent isolated from the resin of Garcinia species in Southeast Asia, exhibits high potency in inhibiting a wide variety of cancer cells growth. Moreover, the fact that it is amenable to chemical modification makes GA an attractive molecule for the development of anticancer agents. Methods: Gambogic acid-3-(4-pyrimidinyloxy) propyl ester (compound 4) was derived from the reaction between 4-hydroxypropoxy pyrimidine and GA. Its structure was elucidated by comprehensive analysis of ESIMS, HRESIMS, 1 D NMR data. Antitumor activities of compound 4 and GA in vitro against HepG-2, A549 and MCF-7 cells were investigated by MTT assay. FITC/PI dye were used to test apoptosis. The binding affinity difference of compound 4 and GA binding to IKKβ was studied by using Discovery Studio 2016. Results: Compound 4 was successfully synthesized and showed strong inhibitory effects on HepG-2, A549 and MCF-7 cells lines with IC50 value of 1.49 ± 0.11, 1.37 ± 0.06 and 0.64 ± 0.16μM, respectively. Molecular docking study demonstrated that four more hydrogen bonds were established between IKKβ and compound 4, compared with GA. Conclusion: Our results suggested that compound 4 showed significant effects in inducing apoptosis. Further molecular docking study indicated that the introduction of pyrimidine could improve GA’s binding affinity to IKKβ. Compound 4 may serve as a potential lead compound for the development of new anticancer drugs.

Annual mortality of 8.2 million could be attributable to cancer globally, posing a serious health issue; particularly, the high number of nonsmall cell lung cancer (NSCLC) diagnosed cases in recent years highlight the need for development in anticancer agents. In NSCLC, a number of specific inhibitors of phosphatidylinositol-3-kinase (PI3K), Protein kinase B (AKT), and mammalian target of rapamycin are currently under development; however, the early evidence has yielded disappointing results. Ent-kaurane diterpenoid compounds from Cronton tonkinensis have been investigated for several bioactivities such as antibacterial, cytotoxic activity, and so on;; however, lung cancer is not yet studied. In this study, we conducted a molecular docking study of 7 ent-kaurane diterpenoids from C tonkinensis against PI3K targeted anticancer therapies; furthermore, their cytotoxicity effects against A549 lung cancer cells were also evaluated. Obtained results indicated that compounds 7, 6, 2, and 1 exhibited significant inhibitory results in comparison to the reference drug oxaliplatin which suggests further in vitro assay for drug development.

A new series of 5-(3,5-dinitrophenyl)-1,3,4-thiadiazole derivatives were prepared and evaluated for their in vitro antimicrobial, antitumor, and DHFR inhibition activity. Compounds 9, 10, 13, and 16 showed strong and broad-spectrum antimicrobial activity comparable to Amoxicillin and Fluconazole as positive antibiotic and antifungal controls, respectively. Compounds 6, 14, and 15 exhibited antitumor activity against four human cancer cell lines, CCRF-CEM leukemia, HCT-15 colon, PC-3 prostate, and UACC-257 melanoma cell lines using Doxorubicin as a reference drug. Compounds 10, 13, 14, and 15 proved to be the most active DHFR inhibitors with an IC50 range of 0.04 ± 0.82–1.00 ± 0.85 µM, in comparison with Methotrexate (IC50 = 0.14 ± 1.38 µM). The highly potent DHFR inhibitors shared a similar molecular docking mode and made a critical hydrogen bond and arene‒arene interactions via Ser59 and Phe31 amino acid residues, respectively.

In connection with our research program concerning development of novel effective benzimidazole-based anticancer candidates, herein we describe a new unexpected synthetic route to obtain a series of 2–((imidazole/benzimidazol2–yl)thio)1–arylethanones endowed with promising anti-breast cancer and Cyclin-dependent kinase 2 (CDK2) inhibitory activities. Contrary to expectations, products for the reaction of 2–mercaptoimidazole/benzimidazole 2a,b with β–keto esters 6a–c were unambiguously assigned as 2–((imidazol/benzimidazol2–yl)thio)1–arylethanones 10a–f based on NMR spectroscopy and single-crystal X-ray crystallographic analyses. In vitro anticancer activities for herein reported imidazole/benzimidazoles 10a–f were assessed through a cell-based assay against human breast cancer T4–7D and MCF–7 cell lines. Benzimidazoles 10d–f exerted better anti-proliferative action towards T4–7D and MCF–7 cell lines than their corresponding imidazole counterparts 10a–c. Furthermore, a molecular docking study suggested CDK2 kinase as a potential enzymatic target for benzimidazoles 10d–f, and investigated their possible binding pattern and interactions within CDK2 active site. Thereafter, benzimidazoles 10d–f were in vitro examined for their CDK2 inhibitory action, where they exerted good activity. Finally, several key ADME and druglikeness properties were predicted by the SwissADME online tool. Interestingly, benzimidazoles 10d–f were found to have no violations in all druglikeness rules (Veber, Lipinski, Ghose, Muegge, and Egan). In addition, they had neither PAINS nor structural alerts (Brenks). In conclusion, benzimidazoles 10d–f demonstrated not only a promising anticancer activities but also an acceptable ADME and physicochemical properties especially benzimidazole 10e.

In an effort to improve and achieve biologically active anticancer agents, a novel series of 1,2,3-triazole-containing hybrids were designed and efficiently synthesized via the Cu-catalyzed azide-alkyne cycloaddition (CuAAC) reaction of substituted-arylazides with alkyne-functionalized pyrazole-[1,2,4]-triazole hybrids. The structure geometry of these new clicked 1,2,3-triazoles was explored by density functional theory (DFT) using the B3LYP/6-311++G(d,p) level; also, the potential activity of the compounds for light absorption was simulated by time-dependent DFT calculations (TD-DFT). The antitumor impacts of the newly synthesized compounds were in vitro estimated to be towards the human liver cancer cell line (HepG-2), the human colon cancer cell line (HCT-116), and human breast adenocarcinoma (MCF-7). Among the tested compounds, conjugate 7 was the most potent cytotoxic candidate towards HepG-2, HCT-116, and MCF-7, with IC50 = 12.22, 14.16, and 14.64 µM, respectively, in comparison to that exhibited by the standard drug doxorubicin (IC50 = 11.21, 12.46, and 13.45 µM). Finally, a molecular docking study was conducted within the epidermal growth factor receptor (EGFR) active site to suggest possible binding modes. Hence, it could conceivably be hypothesized that analogies 7, 6, and 5 could be considered as decent lead candidate compounds for anticancer agents.

In the present paper, new pyrimidine derivatives were designed, synthesized and analyzed in terms of their anticancer properties. The tested compounds were evaluated in vitro for their antitumor activity. The cytotoxic effect on normal human dermal fibroblasts (NHDF) was also determined. According to the results, all the tested compounds exhibited inhibitory activity on the proliferation of all lines of cancer cells (colon adenocarcinoma (LoVo), resistant colon adenocarcinoma (LoVo/DX), breast cancer (MCF-7), lung cancer (A549), cervical cancer (HeLa), human leukemic lymphoblasts (CCRF-CEM) and human monocytic (THP-1)). In particular, their feature stronger influence on the activity of P-glycoprotein of cell cultures resistant to doxorubicin than doxorubicin. Tested compounds have more lipophilic character than doxorubicin, which determines their affinity for the molecular target and passive transport through biological membranes. Moreover, the inhibitory potential against topoisomerase II and DNA intercalating properties of synthesized compounds were analyzed via molecular docking.
