Abstract
In this work is reported the synthesis of 16 new compounds obtained from kokusaginine and flindersiamine, the main alkaloids isolated from the bark of Balfourodendron riedelianum . The activity of the compounds against axenic cultures of Trypanosoma cruzi epimastigtotes and trypomastigotes, as well as intracellular amastigotes, is described, together with their cytotoxic activity against three different human cell lines. The synthetic strategy for the preparation of the new compounds was based on the reactivity at the position C-4 of the furoquinoline core towards nucleophiles. The new derivatives were synthesized by a Buchwald-Hartwig reaction, in most cases under green, solvent free conditions. Compounds 1c and 1e displayed better in-vitro activity against trypomastigotes than benznidazole and nifurtimox (positive controls) with IC 50 < 4 µM. In addition, both compounds were not cytotoxic activity against the three human cell lines K562 (erytroleukimia), LM2 (breast cancer) and HaCat (keratinocyte). Interestingly, when evaluated against intracellular amastigotes, compound 1c was able to significantly reduce the number of this parasite form, compared to the negative control.

Abstract
The standard-of-care treatment for metastatic prostate cancer (PCa) is androgen deprivation therapy (ADT). Nevertheless, most tumors eventually relapse and develop into lethal castration-resistant prostate cancer (CRPC). Docetaxel is a FDA-approved agent for the treatment of CRPC; however, the tumor often quickly develops resistance to this drug. Thus, there is an immediate need for novel therapies to treat docetaxel-resistant PCa. In this study, we modified the structure of CIL-102 and investigated the efficacy of the derivatives against CRPC and docetaxel-resistant PCa. These novel CIL-102 derivatives inhibit CRPC tumorigenicity, including proliferation, migration and colony formation, and importantly, selectively inhibit CRPC cell proliferation over non-cancerous prostate epithelia. Computational modeling indicated the derivatives bind to β-tubulin and immunocytochemistry revealed the depolymerization of microtubules upon treatment. Western blot analyses reveal that pro-apoptotic and anti-oxidant pathways are activated, and MitoSOX and DCF-DA analyses confirmed increased reactive oxygen species (ROS) production upon treatments. Furthermore, CIL-102 derivatives effectively reduce the proliferation of docetaxel-resistant CR PCa cell lines. Our data indicate the potential of these compounds as promising therapeutic agents for CRPC as well as docetaxel-resistant CRPC.

Abstract
CIL-102 (1-[4-(furo[2,3-b]quinolin-4-ylamino)phenyl]ethanone) is a well-known, major active agent of the alkaloid derivative of Camptotheca acuminata with valuable biological properties, including anti-tumorigenic activity. In this study, we investigated the molecular mechanisms by which CIL-102 mediated the induction of cell death, and we performed cell cycle G2/M arrest to clarify molecular changes in colorectal cancer cells (CRC). Treatment of DLD-1 cells with CIL-102 resulted in triggering the extrinsic apoptosis pathway through the activation of Fas-L, caspase-8 and the induction of Bid cleavage and cytochrome c release in a time-dependent manner. In addition, CIL-102 mediated apoptosis and G2/M arrest by phosphorylation of the Jun N-terminus kinase (JNK1/2) signaling pathway. This resulted in the expression of NFκB p50, p300 and CREB-binding protein (CBP) levels, and in the induction of p21 and GADD45 as well as the decreased association of cdc2/cyclin B. Furthermore, treatment with the JNK1/2 (SP600125), NFκB (PDTI) or the p300/CBP (C646) inhibitors abolished CIL-102-induced cell cycle G2/M arrest and reversed the association of cdc2 with cyclin B. Therefore, we demonstrated that there was an increase in the cellular levels of p21 and GADD45 by CIL-102 reduction in cell viability and cell cycle arrest via the activation of the JNK1/2, NFκB p50, p300 and CBP signaling modules. Collectively, our results demonstrated that CIL-102 induced cell cycle arrest and apoptosis of colon cancer cells by upregulating p21 and GADD45 expression and by activating JNK1/2, NFκB p50 and p300 to provide a new mechanism for CIL-102 treatment.

Abstract
A number of 3-phenylquinolinylchalcone derivatives were synthesized and evaluated in vitro for their antiproliferative activities against three breast cancer cell lines (MCF-7, MDA-MB-231, and SKBR-3), and a non-cancer normal epithelial cell line (H184B5F5/M10). Among them, (E)-3-[3-(4-methoxyphenyl)quinolin-2-yl]-1-(3,4,5-trimethoxyphenyl)prop-2-en-1-one (7) was active against the growth of MCF-7, MDA-MB-231, and SKBR-3 with IC50 values of 1.05, 0.75, and 0.78 μM respectively without significant cytotoxicity to the normal H184B5F5/M10 cell line and therefore, was selected as a new lead for further mechanism studies. Results indicated that compound 7 inhibited the polymerization of tubulins, induced G2/M cell cycle arrest via modulation of the cyclin B1, cdk1 and CDC25. Compound 7 ultimately induced cell apoptosis by the increase of apoptotic protein Bax and the decrease of anti-apoptotic protein Bcl-2. In addition, PARP was cleaved while caspase-3 and -8 activities were induced after the treatment of compound 7 for 24 h in a concentration-dependent manner. Thus, compound 7 induces cell cycle arrest at G2/M phase via cleavage of PARP, induces caspase-3 and -8 activities and consequently to cause the cell death. Further study on the structure optimization of 7 is ongoing.

Abstract
Several trifluoromethylquinoline derivatives containing a biologically active benzenesulfonamide moiety 2-14, 16, urea derivatives 15, 17, 4-isothiocyanate 18 and the corresponding carbamimidothioic acid derivatives 19-30, were synthesized from the strategic starting material 4-chloro-7-trifluoromethylquinoline 1. The structures of the newly synthesized compounds were elucidated on the basis of elemental and spectral analyses. All the prepared compounds were evaluated for their in vitro anticancer activity against various cancer cell lines. Most of the synthesized compounds showed good activity, especially compound 15 which exhibited higher activity than the reference drug doxorubicin. In order to suggest the mechanism of action for their cytotoxic activity, molecular docking for all synthesized compounds was done on the active site of PI3K and good results were obtained.

Abstract
A plant dictamine analog, 1-[4-(furo[2,3-b]quinolin-4-ylamino)phenyl]ethanone (CIL-102) has been shown to exert potent anti-tumor activity. In this study, we examined the mode of interaction of CIL-102 with tubulin and unraveled the cellular mechanism responsible for its anti-tumor activity. CIL-102 bound to tubulin at a single site with a dissociation constant ~0.4 μM. Isothermal titration calorimetry revealed that CIL-102-tubulin interaction is highly enthalpy driven and that the binding affords a large negative heat capacity change (ΔC(p) = -790 cal mol(-1) K(-1)) with an enthalpy-entropy compensation. An analysis of the modified Dixon plot suggested that CIL-102 competitively inhibited the binding of podophyllotoxin, a colchicine-binding site agent, to tubulin. Computational modeling indicated that CIL-102 binds exclusively at the β-subunit of tubulin and that CIL-102 and colchicine partially share their binding sites on tubulin. It bound to tubulin reversibly and the binding was estimated to be ~1000 times faster than that of colchicine. CIL-102 potently inhibited the proliferation of MCF-7 cells, induced monopolar spindle formation and multi-nucleation. At half-maximal inhibitory concentration, the spindle microtubules were visibly depolymerized and disorganized. CIL-102 reduced the inter-polar distances of bipolar mitotic cells indicating that it impaired microtubule-kinetochore attachments. CIL-102-treatment induced apoptosis in MCF-7 cells in association with increased nuclear accumulation of p53 and p21 suggesting that apoptosis is triggered through a p53-p21 dependent pathway. The results indicated that CIL-102 exerted anti-proliferative activity by disrupting microtubule functions through tubulin binding and provided important insights into the differential mode of tubulin binding by CIL-102 and colchicine.

Among them, (E)-6-{4-[3-(dimethylamino)propoxy]phenyl}-2-fluoro-9-hydroxy-11H-indeno[1,2-c]quinolin-11-one O-3-(dimethylamino)propyl oxime (23a) was the most active, exhibited GI(50) values of 0.64, 0.39, 0.55, 0.67, and 0.65μM against the growth of Hep G2, Hep 3B, A549, H1299, and MDA-MB-231, respectively. Compound 23a inhibited the growth of hepatoma cell lines in a dose- and time-dependent manner. The proportion of cells was decreased in the G1 and accumulated in G2/M phase after 12h treatment of 23a, while the hypodiploid (sub-G0/G1 phase) cells increased. Further investigations have shown that 23a induced cell cycle arrest at G2/M phase and induce apoptosis via activation of p53, Bax, and caspase-8 which consequently cause cell death.

Abstract
The present report describes the synthesis and antiproliferative evaluation of certain 4-anilino-8-methoxy-2-phenylquinoline and 4-anilino-8-hydroxy-2-phenylquinoline derivatives. The antiproliferative activity of 4'-COMe-substituted derivatives decreased in an order of 6-OMe (1, 3.89 microM) > 8-OMe (8, 10.47 microM) > 8-OH (9, 14.45 microM), indicating that the position of substitution at the quinoline ring is crucial. For 3'-COMe derivatives, the antiproliferative activity of 8-OH (11, 1.20 microM) is more potent than its 8-OMe counterpart (10, 8.91 microM), indicating that a H-bonding donating substituent is more favorable than that of a H-bonding accepting group. Comparison of 8-OH derivatives, the antiproliferative effect of COMe (11) is more potent than its oxime derivative (15a, 2.88 microM), which in turn is more potent than the methyloxime counterpart (15b, 5.50 microM). Compound 11 is especially active against the growth of certain solid cancer cells such as HCT-116 (colon cancer), MCF7, and MDA-MB-435 (breast cancer) with GI50 values of 0.07, <0.01, and <0.01 microM, respectively. Flow cytometric analyses revealed that growth inhibition by 11 and 15a was due to accumulation in S-phase. This result is interesting because 2-phenylquinolone derivatives have been reported to be antimitotic agents which induced cell cycle arrest in G2/M phase.

Abstract
A sensitive high-performance liquid chromatography method with electrochemical detection was developed for the purpose of determining the concentration of the new anti-tumor agent 1-[4-(furo[2,3-b]-quinolin-4-ylamino)phenyl]ethanone (FQPE) in rats. The plasma samples were spiked with the internal standard diclofenac and extracted using dichloromethane. A C(18) 250 mm x 4mm column was used for the separation of analyte with a mobile phase consisting of 50% acetonitrile and 50% pH 3.0 of sodium 1-pentansulfonate solution at a flow rate of 1.0 mL/min. FQPE was detected by electrochemical detector at 1.0 V and 20 nA. Intra-day and inter-day precision and accuracy were acceptable down to the limit of quantization of 1 ng/mL. The lower limit of detection (LOD) was 0.5 ng/mL. The pharmacokinetic parameters of FQPE in rats after intravenous administration of 2.1 and 4.2 mg/kg were determined. The apparent volume of distribution, half-life of elimination, and clearance showed no significant difference between the two dosages. The area under the plasma concentration time curve increased proportionally with dose. The half-life of FQPE was prolonged about 2.4-fold, compared with amsacrine.

Abstract
The present report describes the synthesis and anticancer evaluation of certain 11-substituted 6H-indolo[2,3-b]quinolines and their methylated derivatives. These 6H-indolo[2,3-b]quinoline derivatives 11-13 were prepared from the commercially available 1,4-dihydroxyquinoline through alkylation, chlorination, nucleophilic reaction, and ring cyclization. Depending on the ratio of 11, (MeO)2SO2, and K2CO3, alkylation occurred primarily on N-5 (1:0.8:0.8) or N-6 (1:1.5:1.5) leading to the isolation of 14a or 14b as a major product. Accordingly, major product 15a (2/(MeO)2SO2/K2CO3=1:2:2) or 15b (1:1:1), respectively, was obtained by alkylation of 12 while 16a (13/(MeO)2SO2/K2CO3=1:2:2) or 16b (1:1:1), respectively, was obtained by alkylation of 13. The in vitro anticancer assay indicated 5-methylated derivatives 14a, 15a, 16a are more cytotoxic than their respective 6-methylated counterparts 14b, 15b, 16b and 6H-indolo[2,3-b]quinoline precursors 11, 12, 13. Among them, 11-(4-methoxyanilino)-6-methyl-6H-indolo[2,3-b]quinoline (16a) was the most cytotoxic with a mean GI50 value of 0.78 microM and also exhibited selective cytotoxicities for HL-60 (TB), K-562, MOLT-4, RPMI-8226, and SR with GI50 values of 0.11, 0.42, 0.09, 0.14, and 0.19 microM, respectively.

Abstract
Certain 4-(phenylamino)furo[2,3-b]quinoline and 2-(furan-2-yl)-4-(phenylamino)quinoline derivatives were synthesized and evaluated in vitro against the full panel of NCIs 60 cancer cell lines. The preliminary results indicated these tricyclic 4-(phenylamino)furo[2,3-b]quinolines were more cytotoxic than their corresponding 2-(furan-2-yl)-4-(phenylamino)quinoline isomers. For the 4-(phenylamino)furo[2,3-b]quinolines, compounds 2a and 3d are two of the most potent with a mean GI50 value of 0.025 microM in each case. Inactivity of 2b and 2c (positional isomers of 2a) indicated that both electronic environment, and the distance between intercalating pharmacophore and H-bond-donating MeO group are important. For the 2-(furan-2-yl)-4-(phenylamino)quinoline isomers, compound 12 (a mean GI50 of 4.36 microM), which bears a para-COMe substituent, is more active than its meta-substituted counterpart 13 (10.5 microM). However, the electron-donating MeO substituent is preferred at the meta-position, and the cytotoxicity for the meta-substituted derivatives decreased in the order: MeO derivative 14b (3.05 microM) > oxime 16 (6.85 microM) > ketone 13 (10.5 microM) > methyl oxime 18 (20.6 microM).

Abstract
There have been no therapeutic agents that provide a survival advantage in hormone-refractory prostate cancer. Recently, the Food and Drug Administration approved docetaxel combined with prednisone for the treatment of patients with advanced metastatic prostate cancer, and it does show a survival benefit. Hence, anti-microtubule drugs might be of benefit in chemotherapy of hormone-refractory prostate cancer. We used metastatic hormone-refractory prostate cancer PC-3 cells to investigate potential molecular mechanisms for CIL-102, a semisynthetic alkaloid derivative. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenylte-trazolium bromide and sulforhodamine B assays indicated that CIL-102 inhibits cell growth dose-dependently. Immunofluorescence microscopy and in vitro tubulin assembly assays indicated that CIL-102 binds to tubulin and disrupts microtubule organization. Flow cytometry showed that CIL-102 causes cells to accumulate in G(2)/M phase and sub-G(0)/G(1) phase. CIL-102-induced apoptosis was also characterized by immunofluorescence microscopy. Western blotting and kinase assays showed that CIL-102 exposure induced up-regulation of cyclin B1 and p34(cdc2) kinase activity and olomoucine, a p34(cdc2) inhibitor, profoundly reduced the number of cells accumulated in mitotic phase. Moreover, Bcl-2 phosphorylation, Cdc25C phosphorylation, and survivin expression were increased. CIL-102-induced apoptosis was associated with activation of caspase-3, but a noncaspase pathway may also be involved, since benzyloxycarbonyl-VAD-fluoromethyl ketone, a pancaspase inhibitor, only partially inhibited the apoptosis, and apoptosis-inducing factor was translocated from mitochondria to cytosol. We conclude that CIL-102 induces mitotic arrest and apoptosis by binding to tubulin and inhibiting tubulin polymerization. CIL-102 causes mitotic arrest, at least partly, by modulating cyclin-dependent kinases and then apoptosis executed by caspase and noncaspase pathways.

Abstract
Mast cells, neutrophils and macrophages are important inflammatory cells that have been implicated in the pathogenesis of acute and chronic inflammatory diseases. To explore a novel anti-inflammatory agent, we have synthesized certain 4-anilinofuro[2,3-b]quinoline and 4-phenoxyfuro[2,3-b]quinoline derivatives and evaluated their anti-inflammatory activities by reaction of 3,4-dichlorofuro[2,3-b]quinoline with appropriate Ar-NH(2) or Ar-OH. Compounds 6a and 15 were proved to be more potent than the reference inhibitor, mepacrine for the inhibition of rat peritoneal mast cell degranulation with IC(50) values of 6.5 and 16.4 microM, respectively. Compounds 2b, 6a, 10, and 15 also showed potent inhibitory activity (IC(50)=7.2-29.4 microM) for the secretion of lysosomal enzyme and beta-glucuronidase from neutrophils. These results also indicated that oxime derivatives are more potent than the respective ketone precursors (6a> or =2a; 7a> or =3), and the substituent such as Me at the oxime decreased inhibitory activity (6a> or =6b; 7a> or =7b). Among these derivatives, compound 6a showed the most potent activity with IC(50) values of 6.5-11.6 microM for the inhibition of mast cell degranulation and neutrophil degranulation.
