Phenolic acids and its methoxy derivatives are known to induce caspase-mediated apoptosis activity and exhibit cytotoxic effect towards various cancer cell lines. However, their low stability and poor bioavailability in the human organism extensively restrict the utility of this group of compounds as anticancer and health-promoting agents. In this report, a series of eight novel phosphatidylcholines (3a-b, 5a-b, 7a-b, 8a-b) containing anisic or veratric acids (1a-b) at sn-1 and/or sn-2 positions were synthesized. The phenoylated phospholipids were obtained in good yields 28–66%. The structures of novel compounds were determined by their spectroscopic data. All synthesized compounds were evaluated for their antiproliferative activity towards six cancer cell lines and normal cell line Balb/3T3. Lipophilization of phenolcarboxylic acids significantly increased their anticancer properties. The asymmetrically substituted phenoylated phosphatidylcholines exhibited higher antiproliferative effect than free acids. Lysophosphatidylcholine (7b) effectively inhibited the proliferation of human leukaemia (MV4-11), breast (MCF-7), and colon (LoVo) cancer cell lines at concentrations of 9.5–20.7 µm and was from 19 to 38-fold more active than corresponding free veratric acid. The conjugation of anisic/veratric acids with the phosphatidylcholine have proved the anticancer potential of these phenolcarboxylic acids and showed that this type of lipophilization is an effective method for the production of active biomolecules.

Background: Hybrid molecules furnished by merging two or more pharmacophores is an emerging concept in the field of medicinal chemistry and drug discovery. Currently, coumarin hybrids have attracted the keen attention of researchers to discover their therapeutic capability against cancer. Objective: The present study aimed to evaluate the in vitro antitumor activity of a new series of hybrid molecules containing coumarin and quinolinone moieties 4 and 5 against four cancer cell lines. Materials and Methods: A new series of hybrid molecules containing coumarin and quinolinone moieties, 4a-c and 5a-c, were synthesized and screened for their cytotoxicity against prostate PC-3, breast MCF-7, colon HCT- 116 and liver HepG2 cancer cell lines as well as normal breast Hs-371 T. Results: All the synthesized compounds were assessed for their in vitro antiproliferative activity against four cancer cell lines and several compounds were found to be active. Further in vitro cell cycle study of compounds 4a and 5a revealed MCF-7 cells arrest at G2 /M phase of the cell cycle profile and induction apoptosis at pre-G1 phase. The apoptosis-inducing activity was evidenced by up-regulation of Bax protein together with the downregulation of the expression of Bcl-2 protein. The mechanism of cytotoxic activity of compounds 4a and 5a correlated to its topoisomerase II inhibitory activity. Conclusion: Hybrid molecules containing coumarin and quinolinone moieties represents a scaffold for further optimization to obtain promising anticancer agents.

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.

Abstract Acovenoside A and acobioside A were isolated from Acokanthera oblongifolia. Their anticancer properties were explored regarding, antiproliferative and antiangiogenic activities. The study included screening phase against six cancer cell lines followed by mechanistic investigation against HepG2 cancer cell line. The sulforhodamine-B (SRB) was used to determine their growth inhibitory power. In the other hand, flow cytometry techniques were recorded the cell death type and cell cycle analysis. The clonogenic (colony formation) and wound healing assays, enzyme-linked immunosorbent assay (ELISA) and molecular docking, were performed to evaluate the antiangiogenesis capability. Both compounds were strongly, inhibited four cancer cell lines at GI50 less than 100 nM. The in vitro mechanistic investigation against HepG2 resulted in cell accumulations at G2M phase and induction of apoptosis upon treating cells separately, with 400 nM Acov-A and 200 nM Acob-A. Interestingly, the same concentrations were able to activate caspase-3 by 7.2 and 4.8-fold, respectively. Suppressing the clonogenic capacity of HepG2 cells (20 and 40 nM) and inhibiting the migration of the colon Caco-2 cancer cells were provoke the results of vascular endothelial growth factor receptor2 (VEGFR2) kinase enzyme inactivation. The docked study was highly supportive, to the antiangiogenic approach of both cardenolides. The isolated cardenolides could orchestrate pivotal events in fighting cancer.

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.

A one-pot, single-step, and an atom-economical process towards the synthesis of highly functionalized spirooxindoles analogues was efficiently conducted to produce a satisfactory chemical yields (70–93%) with excellent relative diastereo-, and regio-selectivity. An in vitro antiproliferative assay was carried out on different cancer cell lines to evaluate the biological activity of the synthesized tetrahydro-1’H-spiro[indoline-3,5’-pyrrolo[1,2-c]thiazol]-2-one 5a–n. The prepared hybrids were then tested in vitro for their antiproliferative effects against three cancer cell lines, namely, HepG2 (liver cancer), MCF-7 (breast cancer), and HCT-116 (colon cancer). The spirooxindole analogue 5g exhibited a broad activity against HepG2, MCF-7, and HCT-116 cell lines of liver, breast, and colorectal cancers when compared to cisplatin. Modeling studies including shape similarity, lipophilicity scores, and physicochemical parameters were calculated. The results of this study indicated that spirooxindole analogue 5g retained a good physiochemical parameters with acceptable lipophilicity scores.

The in vitro antiproliferative and antioxidant studies of the leaf extract and fractions of Conyza sumatrensis was investigated by applying the Sulforhodamine-B and 2, 2-diphenyl-1-picrylhydrazyl assays (DPPH-RSA) respectively. While the antiproliferative activity was carried out at 1-250 and 1-100 μg/ mL for the extract and fractions against breast (MCF-7) and lung (NCI-H460) cancer cell lines, the antioxidant study was conducted using DPPH at 31.25 -500 μg/ mL with the total phenolic and flavonoid contents calculated as well with reference to quercetin and gallic acid respectively. The extract and fractions were observed to elicit cytotoxic and growth inhibitory effects against breast (MCF-7) and lung cancer cell lines (NCI-H460) respectively. At 250 μg/mL, the extract of C. sumatrensis gave cytotoxicity of –1.76 ± 0.20 % against MCF-7 cell lines and inhibited growth of NCI-H460 at +94.40 ± 1.0 % respectively. While the chloroform fraction at 100 μg/mL gave -5.38 ± 0.33 % and 91 ± 1.61 % against MCF-7 and NCI-H460 cell lines, the aqueous fraction was observed to be inactive. For the DPPH-RSA activity, the chloroform fraction demonstrated an IC50 value of 125.5 μg/ mL compare to quercetin at 62.5 μg/ mL. The bioactivities were more pronounced in the chloroform fraction. This work has shown that C.  sumatrensis has antiproliferative and antioxidant activities which could be tied to the secondary metabolites present in the plant.
