New pyridine, pyrazoloyridine, and furopyridine derivatives substituted with naphthyl and thienyl moieties were designed and synthesized starting from 6-(naphthalen-2-yl)-2-oxo-4-(thiophen-2-yl)-1,2-dihydropyridine-3-carbonitrile (1). The chloro, methoxy, cholroacetoxy, imidazolyl, azide, and arylamino derivatives were prepared to obtain the pyridine-−C2 functionalized derivatives. The derived pyrazolpyridine-N-glycosides were synthesized via heterocyclization of the C2-thioxopyridine derivative followed by glycosylation using glucose and galactose. The furopyridine derivative 14 and the tricyclic pyrido[3′,2′:4,5]furo[3,2-d]pyrimidine 15 were prepared via heterocyclization of the ester derivative followed by a reaction with formamide. The newly synthesized compounds were evaluated for their ability to in vitro inhibit the CDK2 enzyme. In addition, the cytotoxicity of the compounds was tested against four different human cancer cell lines (HCT-116, MCF-7, HepG2, and A549). The CDK2/cyclin A2 enzyme inhibitory results revealed that pyridone 1, 2-chloro-6-(naphthalen-2-yl)-4-(thiophen-2-yl)nicotinonitrile (4), 6-(naphthalen-2-yl)-4-(thiophen-2-yl)-1H-pyrazolo[3,4-b]pyridin-3-amine (8), S-(3-cyano-6-(naphthaen-2-yl)-4-(thiophen-2-yl)pyridin-2-yl) 2-chloroethanethioate (11), and ethyl 3-amino-6-(naphthalen-2-yl)-4-(thiophen-2-yl)furo[2,3-b]pyridine-2-carboxylate (14) are among the most active inhibitors with IC50 values of 0.57, 0.24, 0.65, 0.50, and 0.93 µM, respectively, compared to roscovitine (IC50 0.394 μM). Most compounds showed significant inhibition on different human cancer cell lines (HCT-116, MCF-7, HepG2, and A549) with IC50 ranges of 31.3–49.0, 19.3–55.5, 22.7–44.8, and 36.8–70.7 μM, respectively compared to doxorubicin (IC50 40.0, 64.8, 24.7 and 58.1 µM, respectively). Furthermore, a molecular docking study suggests that most of the target compounds have a similar binding mode as a reference compound in the active site of the CDK2 enzyme. The structural requirements controlling the CDK2 inhibitory activity were determined through the generation of a statistically significant 2D-QSAR model.

Zanthoxylum nitidum (Roxb.) DC (Rutaceae) is a traditional medicine used for the treatment of various diseases like toothache, gingivitis, fever, colic vomiting, diarrhea, and cholera. Three new alkaloids, zanthocadinanine C (1), 7-methoxy-8-demethoxynitidine (2), and zanthonitiside I (3) were isolated from the stems and twigs of Z. nitidum. Their structures were determined on the basis of extensive spectroscopic, including 1-dimensional and 2-dimensional nuclear magnetic resonance and mass spectroscopy data. Compounds 1–3 were evaluated for cytotoxic activity against 5 human cancer cell lines, KB, MCF-7, LNCaP, HepG-2, and LU-1. Compound 2 showed significant cytotoxic activity against all tested human cancer cell lines with IC50 values ranging from 10.3 to 12.6 µM.

Abstract Novel glucosylated (-)-epigallocatechin-3-gallate derivatives 10 – 13 having the EGCG analogues conjugated to the D-glucosyl azide were synthesized by carrying out the copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction, and were evaluated for their cytotoxicities against a panel of five human cancer cell lines (HL-60, SMMC-7721, A-549, MCF-7 and SW480) using MTT assays. Compounds 10 and 11 showed the highest levels of cytotoxicity against the HL-60 cells with IC50 values of 4.57 μM and 3.78 μM, respectively, and showed moderate selectivity towards cancer cell lines. Compound 11 was also shown to induce apoptosis in HL-60 cells. Most notably, inclusion of the perbutyrylated glucose residue in an EGCG derivative was concluded to lead to increased anticancer activity.

Their structures were established on the basis of spectral and chemical evidence. The cytotoxicity of all compounds was evaluated by MTT assay on four human cancer cell lines, HepG2, KB, LU-1, and MCF-7. Compounds 1 and 2 exhibited moderate cytotoxic activities on the four human cancer cell lines with IC50 values ranging of 20.7 - 28.9 μg/mL.

In continuation of our study on anticancer compounds, a series of novel artemisinin dimers have been synthesized and evaluated for their cytotoxic effects against three human cancer cell lines, including HepG2 (liver cancer), MCF-7(breast cancer) and HL-60 (leukemia cancer). The assay results showed that most of the compounds displayed inhibitory effects against all three human cancer cell lines tested, and seemed to be more cytotoxic toward the blood cancer cells (HL-60) than liver (HepG2), and breast (MCF-7) cancer cells. Among the synthesized artemisinin dimers, the compound 10d with a double bond bridge exhibited the most potent cytotoxicity with IC50 values of 5.08, 4.82 and 1.32 µg/mL against the HepG2, MCF-7, and HL-60 cell lines, respectively.

Using various chromatographic methods, one new sesquiterpene quinone named smenohaimien F (1) and five known, neodactyloquinone (2), dactyloquinone C (3), dactyloquinone D (4), isoamijiol (5), and amijiol (6), were isolated from the marine sponge Smenospongia cerebriformis Duchassaing & Michelotti, 1864. Their structures were elucidated by 1D-, 2D-NMR spectroscopic analysis, HR-ESI-MS, and by comparing with the NMR data reported in the literature. The cytotoxic activities of the all compounds were evaluated on five human cancer cell lines, LU-1, HL-60, SK-Mel-2, HepG-2, and MCF-7. Compound 4 was found to exhibit significant cytotoxic activities on all tested human cancer cell lines with IC50 values ranging from 0.7 to 1.6 μg/mL.
