Abstract In the present study, the various 28 hybrid molecules containing hydrazone and sulfonate moiety were synthesized and characterized by FTIR, 1H-NMR, 13C-NMR spectroscopy and LC-MS spectrometry, besides elemental analysis. The compounds were evaluated for their antiproliferative effects against six cancer cell lines, namely A549 (non-small cell lung cancer), MCF-7 (breast cancer), HT-29 (colorectal adenocarcinoma cancer), PC-3 (androgen-independent prostate adenocarcinoma), Hep3B (hepatocellular carcinoma cancer), and HeLa (epitheloid cervix carcinoma cancer). Among all the target compounds, compounds 4g and 4h exhibited more promising effects on MCF-7 cell lines (IC50=17.8 mM and 21.2 mM, respectively) with high selectivity. Further mechanistic studies proposed that compounds 4g and 4h induced apoptosis is mediated through the intrinsic apoptotic pathway with changes in mitochondrial membrane potential by finally activating caspase-9 and caspase-3. The results have been encouraging enough to merit further investigation.

Abstract Many studies have shown that hederacolchiside A1 (HA1) is an important anticancer saponin, although its mechanism of action and in vivo investigations are still lacking. Our previous results revealed that HA1 may have the potential to treat breast cancer. Therefore, we attempted to verify the potential anti-breast cancer effect of HA1 in vitro and in vivo. MTT, flow cytometry, DCFH-DA fluorescence microscopy, and western blotting were used to evaluate the activities and mechanisms of action of HA1. Athymic nude mice were used to demonstrate the antitumor activity of HA1 in vivo. HA1 exhibited significant cytotoxic effects on HepG2, MCF-7, MDA-MB-231, SKBr-3, HT-29, and HCT-116 cells, especially MCF-7 cells. HA1 blocked the sub-G1 and G0/G1 phases, induced apoptosis, promoted reactive oxygen species (ROS) generation, and decreased the mitochondrial membrane potential of MCF-7 cells. HA1 upregulated Bax and downregulated Bcl-2 levels and activated caspase-9 and caspase-3 in MCF-7 cells Meanwhile, HA1 inhibited the phosphorylation of JAK2/STAT3 in MCF-7 cells. In addition, 50 and 100 mg/kg HA1 significantly inhibited the growth of transplanted tumors with inhibition rates of 46.95 ± 26.72% and 48.45 ± 22.36%, respectively. This preliminary study demonstrated that HA1 could inhibit proliferation and induce the apoptosis of MCF-7 cells via ROS-mediated activation of the mitochondrial apoptotic pathway and JAK2/STAT3 inactivation. HA1 may therefore be developed as a novel agent for breast cancer therapy.

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.

Apoptotic Effects

Background and Objective: Histone deacetylases (HDACs) are important therapeutic targets for many types of human cancers. A derivative of valproic acid, N-(2-hydroxyphenyl)-2-propylpentanamide (HO-AAVPA), has antiproliferative properties on some cancer cell lines and inhibits the HDAC1 isoform. Materials and Methods: In this work, HO-AAVPA was tested as an antiproliferative agent in U87-MG (human glioblastoma) and U-2 OS cells (human osteosarcoma), which are types of cancer that are difficult to treat, and its antiangiogenic properties were explored. Results: HO-AAVPA had antiproliferative effects at 48 h with an IC50 = 0.655 mM in U87-MG cells and an IC50 = 0.453 mM in U-2 OS cells. Additionally, in the colony formation assay, HO-AAVPA decreased the number of colonies by approximately 99% in both cell lines and induced apoptosis by 31.3% in the U-2 OS cell line and by 78.2% in the U87-MG cell line. Additionally, HO-AAVPA reduced the number of vessels in chorioallantoid membranes (CAMs) by approximately 67.74% and IL-6 levels in both cell lines suggesting that the biochemical mechanism on cancer cell of HO-AAVPA is different compared to VPA. Conclusion: HO-AAVPA has antiproliferative effects on glioblastoma and osteosarcoma and antiangiogenic properties.

A novel series of 4-anilinoquinazoline analogues, DW (1–10), were evaluated for anticancer efficacy in human breast cancer (BT-20) and human colorectal cancer (CRC) cell lines (HCT116, HT29, and SW620). The compound, DW-8, had the highest anticancer efficacy and selectivity in the colorectal cancer cell lines, HCT116, HT29, and SW620, with IC50 values of 8.50 ± 2.53 µM, 5.80 ± 0.92 µM, and 6.15 ± 0.37 µM, respectively, compared to the non-cancerous colon cell line, CRL1459, with an IC50 of 14.05 ± 0.37 µM. The selectivity index of DW-8 was >2-fold in colon cancer cells incubated with vehicle. We further determined the mechanisms of cell death induced by DW-8 in SW620 CRC cancer cells. DW-8 (10 and 30 µM) induced apoptosis by (1) producing cell cycle arrest at the G2 phase; (2) activating the intrinsic apoptotic pathway, as indicated by the activation of caspase-9 and the executioner caspases-3 and 7; (3) nuclear fragmentation and (4) increasing the levels of reactive oxygen species (ROS). Overall, our results suggest that DW-8 may represent a suitable lead for developing novel compounds to treat CRC.

AbstractAmmonium benzyldithiocarbamate, represented as NH4L, was prepared and used in the complexation reaction involving three organotin(iv) salts, represented as R2SnCl2 (R = CH3, C4H9, and C6H5). The structures of the synthesized complexes [(CH3)2SnL2] (1), [(C4H9)2SnL2] (2), and [(C6H5)2SnL2] (3) were established using various spectroscopic techniques (Fourier transform infrared spectroscopy, 1H NMR, 13C NMR, and 119Sn NMR) and elemental analysis. Thermal decomposition of the complexes using thermogravimetric analysis under nitrogen showed no definite pathway in the pattern of the complexes even though they are structurally related. X-ray diffraction studies of the final residue showed a common diffraction pattern for the complexes and confirmed SnS as the product of the thermal treatment. Cytotoxicity studies of these complexes against the human tumor cell lines (HeLa and MCF-7) compared favorably with the used standard 5-fluorouracil drug, with complexes 2 and 3 showing very good activity toward the used cell lines.

Among women worldwide, ovarian cancer is one of the most dangerous cancers. Patients undergoing platinum-based chemotherapy might get adverse side effects and develop resistance to drugs. In recent years, natural compounds have aroused growing attention in cancer treatment. Galangin inhibited the growth of two cell lines, A2780/CP70 and OVCAR-3, more strongly than the growth of a normal ovarian cell line, IOSE 364. The IC50 values of galangin on proliferation of A2780/CP70, OVCAR-3 and IOSE 364 cells were 42.3, 34.5, and 131.3 μM, respectively. Flow cytometry analysis indicated that galangin preferentially induced apoptosis in both ovarian cancer cells with respect to normal ovarian cells. Galangin treatment increased the level of cleaved caspase-3 and -7 via the p53-dependent intrinsic apoptotic pathway by up-regulating Bax protein and via the p53-dependent extrinsic apoptotic pathway by up-regulating DR5 protein. By down-regulating the level of p53 with 20 μM pifithrin-α (PFT-α), the apoptotic rates of OVCAR-3 cells induced by galangin treatment (40 μM) were significantly decreased from 18.2% to 10.2%, indicating that p53 is a key regulatory protein in galangin-induced apoptosis in ovarian cancer cells. Although galangin up-regulated the expression of p21, it had little effect on the cell cycle of the two ovarian cancer cell lines. Furthermore, the levels of phosphorylated Akt and phosphorylated p70S6K were decreased through galangin treatment, suggesting that the Akt/p70S6K pathways might be involved in the apoptosis. Our results suggested that galangin is selective against cancer cells and can be used for the treatment of platinum-resistant ovarian cancers in humans.

Dihydrochalcone derivatives are active compounds that have been purified from the Thai medicinal plant Cyathostemma argenteum. The objectives of this study were to investigate the effects of two dihydrochalcone derivatives on human breast cancer MDA-MB-231 and MCF-7 cell proliferation and to study the relevant mechanisms involved. The two dihydrochalcone derivatives are 4′,6′-dihydroxy-2′,4-dimethoxy-5′-(2″-hydroxybenzyl)dihydrochalcone (compound 1) and calomelanone (2′,6′-dihydroxy-4,4′-dimethoxydihydrochalcone, compound 2), both of which induced cytotoxicity toward both cell lines in a dose-dependent manner by using MTT assay. Treatment with both derivatives induced apoptosis as determined by annexin V-FITC/propidium iodide employing flow cytometry. The reduction of mitochondrial transmembrane potential (staining with 3,3′-dihexyloxacarbocyanine iodide, DiOC6, employing a flow cytometer) was established in the compound 1-treated cells. Compound 1 induced caspase-3, caspase-8, and caspase-9 activities in both cell lines, as has been determined by specific colorimetric substrates and a spectrophotometric microplate reader which indicated the involvement of both the extrinsic and intrinsic pathways. Calcium ion levels in mitochondrial and cytosolic compartments increased in compound 1-treated cells as detected by Rhod-2AM and Fluo-3AM intensity, respectively, indicating the involvement of the endoplasmic reticulum (ER) stress pathway. Compound 1 induced cell cycle arrest via enhanced atm and atr expressions and by upregulating proapoptotic proteins, namely, Bim, Bad, and tBid. Moreover, compound 1 significantly inhibited the EGFR/MAPK signaling pathway. In conclusion, compound 1 induced MDA-MB-231 and MCF-7 cell apoptosis via intrinsic, extrinsic, and ER stress pathways, whereas it ameliorated the EGFR/MAPK pathway in the MCF-7 cell line. Consequently, it is believed that compound 1 could be effectively developed for cancer treatments.

2′-hydroxyflavanone (2HF) is a dietary flavonoid with anticancer activity towardsmultiple cancers. Here, we report that topically applied 2HF inhibits the growth of intradermalimplants of melanoma in immunocompetent mice. 2HF induced apoptosis and inhibited the growthof the human SK-MEL-24 as well as murine B16-F0 and B16-F10 melanoma cell lines in vitro.Apoptosis was associated with depletion of caspase-3, caspase-9, and PARP1 in B16-F0 and SKMEL-24 cells. Caspase-9 and MEKK-15 were undetected even in untreated B16-F10 cells. Signalingproteins TNFα, and phospho-PDGFR-β were depleted in all three cell lines; MEKK-15 was depletedby 2HF in SK-MEL-24 cells. 2HF enhanced sunitinib (an MEK and PDGFR-β inhibitor) and AZD2461 (a PARP1 inhibitor) cytotoxicity. 2HF also depleted the Ral-regulated, stress-responsive,antiapoptotic endocytic protein RLIP76 (RALBP1), the inhibition of which has previously beenshown to inhibit B16-F0 melanoma growth in vivo. Functional inhibition of RLIP76 was evidentfrom inhibition of epidermal growth factor (EGF) endocytosis by 2HF. We found that topicallyapplied 2HF–Pluronic Lecithin Organogel (PLO) gel inhibited B16-F0 and B16-F10 tumorsimplanted in mice and caused no overt toxicity despite significant systemic absorption. 2HFtreatment reduced phospho-AKT, vimentin, fibronectin, CDK4, cyclinB1, and BCL2, whereas itincreased BIM and phospho-AMPK in excised tumors. Several cancer signals are controlled byendocytosis, a process strongly inhibited by RLIP76 depletion. We conclude that 2HF–PLO gel maybe useful for topical therapy of cutaneous metastases of melanoma and could enhance theantineoplastic effects of sunitinib and PARP1 inhibitors. The mechanism of action of 2HF inmelanoma overlaps with RLI76 inhibitors.

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.
