Eighteen novel chalcone derivatives containing indole and naphthalene moieties (2?19) were synthesized and characterized by 1H-NMR, 13C-NMR and high resolution (HR)-MS spectra. All compounds were evaluated for their in vitro cytotoxic potential against human hepatocellular carcinoma (HepG2), human colon carcinoma (HCT116) and human breast adenocarcinoma (MCF-7) cell lines. Among them, compound 2, 3, 4 and 7 showed potent activities against tested cancer cell lines. More significantly, compound 7 exhibited the most potent cytotoxic activity against HepG2, HCT116 and MCF-7 with IC50 values of 0.65, 1.13 and 0.82muM, respectively. Furthermore, flow cytometry analysis indicated that compound 7 arrested cancer cells in G2/M phase. The compound 7 also displayed significant inhibition of tubulin polymerization (IC50=3.9muM). Finally, molecular docking studies were performed to explore the possible interactions between compound 7 and tubulin binding pockets.

We report herein an efficient gold(I)-catalyzed post-Ugi domino dearomatization/ipso-cyclization/Michael sequence that enables access to libraries of diverse (hetero)arene-annulated tricyclic heterocycles. This process affords novel complex polycyclic scaffolds in moderate to good yields from readily available acyclic precursors with excellent chemo-, regio-, and diastereoselectivity. The power of this strategy has been demonstrated by the rapid synthesis of 40 highly functionalized polyheterocycles bearing indole, pyrrole, (benzo)furan, (benzo)thiophene, pyrazole, and electron-rich arene groups in two operational steps.

2,2?,4,4?-tetrahydroxybenzophenone (Uvinul D50), a sunscreen used in cosmetics, has two effects in the melanin biosynthesis pathway. On the one hand, it acts a weak inhibitor of tyrosinase and on the other, it accelerates the conversion of dopachrome to melanin. Uvinul D50 was seen to behave as a weak competitive inhibitor: apparent constant inhibition = 2.02 ± 0.09 mM and IC50 = 3.82 ± 0.39 mM established in this work. These values are higher than those in the bibliography, which tend to be undersetimated. This discrepancy could be explained by the reaction of Uvinul D50 with the dopachrome produced from L-tyrosine or L-dopa, which would interfere in the measurement. Based on studies of its docking to tyrosinase, it seems that Uvinul D50 interacts with the active site of the enzyme (oxytyrosinase) both in its protonated and deprotonated forms (pKa = 7). However, it cannot be hydroxylated, meaning that it acts as a weak inhibitor, not as an alternative substrate, despite its resorcinol structure. Uvinul D50 can be used as sunscreen, in low concentrations without significant adverse effects on melanogenesis.

Multimodal imaging provides distinct advantages over traditional single modal imaging. The combined modalities of magnetic resonance imaging (MRI) and near-infrared imaging (NIR), in particular, provide a powerful tool for tumor diagnosis. In this study, a bimodal MRI and NIR self-assembled supramolecular nanoparticle was developed via the self-assembly of host-guest interactions between hyaluronic acid?beta-cyclodextrin (HA?CD) and amantadine (Ad)-modified imaging agents (Gd?DOTA and NIR cyanine dye Cy7). The supramolecular HA?CD?GC nanoparticles (NPs) were characterized by transmission electron microscopy (TEM), Zeta potential, and dynamic light-scattering (DLS) experiments. The relaxivity and fluorescent properties of the NPs were also determined. HA?CD?GC NPs exhibited an enhanced relaxivity of 11.4 mM?1S?1, which was three-fold higher than that of clinical Gd3+-chelated complex, for MRI imaging. Moreover, HA?CD?GC NPs displayed excellent fluorescence. In addition, HA?CD?GC NPs were internalized into tumor cells via HA-receptor CD44-mediated endocytosis. Therefore, the self-assembled HA?CD?GC NPs are effective targeted tumor cell imaging systems and have potential applications in cancer diagnosis and treatment.

Molecules labeled with fluorine-18 (18F) are used in positron emission tomography to visualize, characterize and measure biological processes in the body. Despite recent advances in the incorporation of 18F onto arenes, the development of general and efficient approaches to label radioligands necessary for drug discovery programs remains a significant task. This full account describes a derisking approach toward the radiosynthesis of heterocyclic positron emission tomography (PET) radioligands using the copper-mediated 18F-fluorination of aryl boron reagents with 18F-fluoride as a model reaction. This approach is based on a study examining how the presence of heterocycles commonly used in drug development affects the efficiency of 18F-fluorination for a representative aryl boron reagent, and on the labeling of more than 50 (hetero)aryl boronic esters. This set of data allows for the application of this derisking strategy to the successful radiosynthesis of seven structurally complex pharmaceutically relevant heterocycle-containing molecules.

An efficient synthesis of tetrahydrocarboline-type products and polycyclic spiroindolines has been achieved. The transformation proceeds via rhodium(II)-catalyzed intramolecular annulations of indolyl- and pyrrolyl-tethered N-sulfonyl-1,2,3-triazoles. The reaction could be tuned toward either the formal [3 + 2] cycloaddition or the C-H functionalization reaction depending on the electronic and structural features of the substrates, leading to the production of a variety of structurally related heterocyclic compounds.

Background: Among the different types of cancers, breast cancer, bone cancer and cervical cancer are the most common gender specific cancer types that are affecting the women worldwide. Currently, many enzymatic and cellular pathways are known as drug targets for the treatment of cancer. Even though many improvements have been made in the therapy of various types of cancer, but the major disadvantage of available anti-cancer drugs is their non-selective behavior towards cancer cells as well as normal cells. Objectives: In the light of this fact, the searching of new compounds with selective behavior only towards cancer cells is critically important. Previously, we have identified several series of compounds as the potential inhibitors of these families. Methods: Herein, we investigate quinolones and quinolines for their anti-cancer activity against breast cancer cells (MCF?7), bone marrow cancer cells (K?562) and cervical cancer cells (HeLa) by MTT assay. The most effective derivatives were further subjected to flow cytometry analysis followed by fluorescence microscopic analysis by using 4´,6-diamidine-2´-phenylindole (DAPI) and propidium staining (PI) staining. Results: All the tested compounds were found selective only towards cancer cells. The identified compounds also induced either G2 or S-phase cell cycle arrest within the respective cancer cell line, chromatin condensation and the nuclear fragmentation, as well as maximum interaction with DNA. Conclusions: These results provide evidence that the characteristic chemical features of attached groups are the key factors for their anticancer effects and play a useful role in revealing the mechanisms of action in relation to the known compounds in future research programs.

The antioxidant, anti-microbial activity and potential application of oil palm (Elaeis guineensis) leaf extract (OPLE) as a skin lightening and sunscreen agent in topical application were evaluated. Currently, there are no evidence of skin lightening effect and protection against ultraviolet (UV) irradiation of OPLE. OPLE contains 9.84±0.06 mg gallic acid equivalent per gram of dry extract and shows antioxidant activity through 2,2-diphenyl-1-picrylhydrazyl assay with IC50 of 247±0.58 mug ml-1. OPLE was effective only against gram-positive bacteria and the minimum inhibitory concentration was 12.5 mg ml-1. OPLE also inhibited mushroom tyrosinase enzyme with IC50 254.88 mug ml-1. Determination of UV spectrophotometric and in vitro sun protection factor (SPF) indicated that OPLE provides a protection against ultraviolet B (UVB) and ultraviolet A (UVA) irradiation. OPLE were mixed with glycerine at 1%, 5% and 10% concentrations and showed slightly increase in SPF values from 0.96, 1.48 and 1.87, respectively. The U VA/UVB ratios were significantly increase from 0.076 for glycerine to 0.645, 0.906 and 0.910 for OPLE at 1%, 5% and 10% in glycerine, respectively. OPLE showed potentially good UV absorbance at UVB and U VA range wavelength and can be used as natural sunscreen and skin lightening agent for topical application.
