Design, synthesis and biochemical evaluation of novel ethanoanthracenes and related compounds to target burkitt’s lymphoma

Lymphomas (cancers of the lymphatic system) account for 12% of malignant diseases worldwide. Burkitt’s lymphoma (BL) is a rare form of non-Hodgkin’s lymphoma in which the cancer starts in the immune B-cells. We report the synthesis and preliminary studies on the antiproliferative activity of a library of 9,10-dihydro-9,10-ethanoanthracene based compounds structurally related to the antidepressant drug maprotiline against BL cell lines MUTU-1 and DG- 75. Structural modifications were achieved by Diels-Alder reaction of the core 9-(2- nitrovinyl)anthracene with number of dienophiles including maleic anhydride, maleimides, acrylonitrile and benzyne. The antiproliferative activity of these compounds was evaluated in BL cell lines EBV? MUTU-1 and EBV+ DG-75 (chemoresistant). The most potent compounds 13j, 15, 16a, 16b, 16c, 16d and 19a displayed IC50 values in the range 0.17–0.38 μM against the BL cell line EBV? MUTU-1 and IC50 values in the range 0.45–0.78 μM against the chemoresistant BL cell line EBV+ DG- 75. Compounds 15, 16b and 16c demonstrated potent ROS dependent apoptotic effects on the BL cell lines which were superior to the control drug taxol and showed minimal cytotoxicity to peripheral blood mononuclear cells (PBMCs). The results suggest that this class of compounds merits further investigation as antiproliferative agents for BL.

Design, synthesis and biological evaluation of novel 3,4-dihydro-2(1H)-quinolinone derivatives as potential chitin synthase inhibitors and antifungal agents

A series of 3,4-dihydro-2(1H)-quinolinone derivatives contained butenediamide fragment were designed and synthesized. Their inhibition potency against chitin synthase and antimicrobial activities were screened in vitro. The enzymatic assays showed that all the synthesized compounds had inhibition potency against chitin synthase at concentration of 300 μg/mL. Compound 2d displayed excellent potency with inhibition percentage (IP) value of 82.3%, while IP value of the control polyoxin B was 87.5%. Compounds 2b, 2e and 2s whose IP values were above 70% showed good inhibition potency against chitin synthase. Moreover, the IC50 value of 2b was comparable with that of polyoxin B (0.09 mM). The Ki of compound 2b was 0.12 mM and the result from Lineweaver-Burk plot showed that 2b was non-competitive inhibitor to bind chitin synthase. The antifungal experiment showed that these compounds had excellent antifungal activity against fungal strains, especially for candida albicans. The antifungal activities against C .albicans of compounds 2b, 2d, 2e and 2l were comparable with that of fluconazole and were superior to that of polyoxin B. Meanwhile, the other compounds against C. albicans showed better antifungal activity (MIC 2 μg/mL) than polyoxin B except for compound 2n (MIC 4 μg/mL). The trial of drug combination use showed that these synthesized compounds had synergistic effects with fluconazole and polyoxin B. It indicated that these compounds were not competing with polyoxin B to bind with chitin synthase, which was also consistence with the result of enzymatic assays. The antibacterial experiment showed that these compounds had no activity against selected strains including three Gram-positive and three Gram-negative bacteria. These results showed that the designed compounds were chitin synthase inhibitors and had selective antifungal activity.

Alizarin red S-TiO2-catalyzed cascade C(sp3)-H to C(sp2)-H bond formation/cyclization reactions toward tetrahydroquinoline derivatives under visible light irradiation

A very low amount of organic dye (Alizarin red S) sensitized TiO2 and it was successfully used to catalyze cascade C(sp3)-H to C(sp2)-H bond formation/cyclization reactions under visible light irradiation. The modified TiO2 photocatalyst efficiently, for the first time, advanced [4+2] cyclization of N,N-dimethylanilines and maleimides to the corresponding tetrahydroquinolines in air atmosphere. The reaction proceeds through α-amino radicals without additional oxidant at ambient temperature to afford products in good to excellent yields.

Solvent-free and room temperature visible light-induced C-H activation: CdS as a highly efficient photo-induced reusable nano-catalyst for the C-H functionalization cyclization of: T -amines and C-C double and triple bonds

Nano-sized CdS was successfully prepared, fully characterized and applied as a highly efficient reusable photocatalyst for the synthesis of pyrrolo[3,4-c]quinolone and pyrrolo[2,1-a]isoquinoline-8-carboxylate derivatives through a condensation reaction of N,N-dimethylanilines or alkyl 2-(3,4-dihydroisoquinolin-2(1H)-yl)acetates with maleimides via a C-H activation approach under benign and eco-friendly conditions at room temperature without using any solvent and oxidant under visible light irradiation. Besides, the prepared photocatalyst has been successfully applied for the condensation reaction of N,N-dimethylanilines with alkyl but-2-ynedioates or phenyl acetylenes for the synthesis of novel 1,2-dihydroquinoline-3,4-dicarboxylate and aryl-1,2-dihydroquinoline derivatives for the first time. Using this method, all favourable products were obtained in good yields and relatively short reaction times under benign conditions with the application of visible light irradiation, a renewable energy source. The catalyst was easily recovered and reused several times without any loss of its activity.

Graphene Oxide as a Carbocatalyst for a Diels–Alder Reaction in an Aqueous Medium

The Diels–Alder (DA) reaction, a [4+2] cycloaddition reaction, is highly important in synthetic organic chemistry and is frequently used in the synthesis of natural products containing six-membered rings. Herein, we report an efficient protocol for the DA reaction between 9-hydroxymethylanthracene and N-substituted maleimides using two-dimensional graphene oxide (GO) as a heterogeneous carbocatalyst in an aqueous medium at room temperature. High yields, a wide substrate scope, low temperature, excellent functional group tolerance, atom economy, and water as a green solvent are noteworthy features of this protocol. The heterogeneous GO catalyst can be easily recovered and used multiple times without any significant loss in catalytic activity.

Chemical reactivity and antimicrobial activity of N-substituted maleimides

Several N-substituted maleimides containing substituents of varying bulkiness and polarity were synthesised and tested for antimicrobial and cytostatic activity. Neutral maleimides displayed relatively strong antifungal effect minimum inhibitory concentrations (MICs in the 0.54 g ml-1 range); their antibacterial activity was structure dependent and all were highly cytostatic, with IC50 values below 0.1 g ml-1. Low antimicrobial but high cytostatic activity was noted for basic maleimides containing tertiary aminoalkyl substituents. Chemical reactivity and lipophilicity influenced antibacterial activity of neutral maleimides but had little if any effect on their antifungal and cytostatic action. N-substituted maleimides affected biosynthesis of chitin and β(1,3)glucan, components of the fungal cell wall. The membrane enzyme, β(1,3)glucan synthase has been proposed as a putative primary target of N-ethylmaleimide and some of its analogues in Candida albicans cells.
