Synthesis and in vitro antitumor activity of novel 2-alkyl-5-methoxycarbonyl-11-methyl-6H-pyrido[4,3-b]carbazol-2-ium and 2-alkylellipticin-2-ium chloride derivatives
摘要:
Twenty-one types of novel ellipticine derivatives and pyridocarbazoles (5-methoxycarbonyl-11-methyl-6H-pyrido[4,3-b]carbazoles) with a nitrosourea moiety, linked by an oxydiethylene unit at the 2 position, were synthesized, and their cytotoxicity against HeLa S-3 cells was evaluated. Some of these new compounds exhibited potent antitumor activity by comparison with that of ellipticine. (C) 2014 Elsevier Masson SAS. All rights reserved.

resistance of bacteria to current antibiotics, novel compounds are urgently needed to treat bacterial infections. Streptozotocin (STZ) is a natural product that has broad-spectrumantibiotic activity, albeit with limited use because of its toxicity to pancreatic β cells. In an attempt to derivatize STZ through structural modification at the C3 position, we performed the synthesis of three novel STZ analogues
Synthesis and cytotoxic activity of novel 11-methyl-6H-pyrido[4,3-b]carbazole derivatives linked to amine, N-methylurea, and N-methyl-N-nitrosourea moieties with various types of carbamoyl tethers at the C-5 atom

A novel macroreticular-type fluorous polystyrene resin and its application to the synthesis of a 3-amino-β-carboline derivative with N-methyl-N-nitrosourea conjugation via fluorous solid-phase reaction: a comparative study of fluorous solid-, solid-, and liquid-phase reactions
A novel fluorous polystyrene (FPS) MR-resin was applied to a fluorous solid-phase (FSP) reaction. The MR-FPS resin actually was developed previously and possessed excellent chemical resistance to acids and alkalis, and a fluorous-tagged compound was homogeneously and loosely immobilized on the resin. The synthesis of an antitumor drug, an N-methyl-N-nirosourea conjugated 3-amino-beta-carboline derivative, was accomplished with a high yield by using this new fluorous reaction system. Using only filtration, the fluorous 3-amino-beta-carboline derivatives immobilized on the MR-FPS resin were easily recovered from the reaction mixtures. As an extention of this approach, a diversity synthesis of 3-amino-9-benzyl-beta-carboline derivatives was applied to the FSP method giving high yields. Finally, the FSP synthesis was compared with the corresponding conventional solid- and liquid-phase methods of synthesis. The FSP reaction was superior in terms of the reactivity of the substrate and the ease of product separation. (C) 2015 Elsevier Ltd. All rights reserved.
