  Synthesis and biological evaluation of 1,9-disubstituted β-carbolines as potent DNA intercalating and cytotoxic agents

  摘要：

  A series of novel 1,9-disubstituted beta-carbolines was designed, synthesized and evaluated as cytotoxic and DNA intercalating agents. Compounds 7b, 7c, 8b and 8c exhibited the most potent cytotoxic activities with IC50 values of lower than 20 mu M against ten human tumor cell lines. The results indicated that (1) the 3-chlorobenzyl and 3-phenylpropyl substituents in position-9 of beta-carboline nucleus were the suitable pharmacophoric group giving rise to significant antitumor agents; (2) the length of the alkylamino side chain moiety affected their cytotoxic potencies, and three CH2 units were more favorable. In addition, these compounds were found to exhibit remarkable DNA intercalating effects. (C) 2011 Elsevier Masson SAS. All rights reserved.

  A series of novel beta-carbolinium bromides has been synthesized from easily accessible beta-carbolines and 1-aryl-2-bromoethanones. The newly synthesized compounds were evaluated for their in vitro anticancer activity. Among the synthesized derivatives, compounds 161, 16o and 16s exhibited potent anticancer activity with IC50 values of <10 mu M against tested cancer cell lines. The most potent analogue 161 was broadly active against all the tested cancer cell lines (IC50 = 3.16-7.93 mu M). In order to test the mechanism of cell death, we exposed castration resistant prostate cancer cell line (C4-2) to compounds 161 and 16s, which resulted in increased levels of cleaved PARP1 and AO/EB staining, indicating that a-carbolinium salts induce apoptosis in these cells. Additionally, the most potent beta-carbolines 161 and 16s were found to inhibit tubulin polymerization. (C) 2017 Elsevier Ltd. All rights reserved.
• Exploiting the Polypharmacology of ß-Carbolines to Disrupt <i>O. volvulus</i> Molting

  Onchocerciasis is an infection caused by the filarial worm Onchocerca volvulus, which can eventually result in blindness. The lack of an effective macrofilaricide and the possible development of ivermectin-resistant strains of O. volvulus necessitate the, need for alternative treatment strategies. We have shown that targeting the L3-stagespecific chitinase OvCHT1 impairs the shedding of the filarial cuticle. In our continued efforts to discover OvCHT1 inhibitors, we identified the beta-carboline alkaloid scaffolding as a chitinase inhibitor that is capable of penetrating the worm cuticle. Herein, we disclose the rich polypharmacology of the beta-carboline class of compounds as an approach to abrogate the molting of the parasite and thus the initiation of infection in the human host.

  To further our SAR study on the chemistry and antitumor activity/neurotoxicity of beta-carboline alkaloids. several series of beta-carboline derivatives with various substituents were designed and synthesized from the starting material L-tryptophan on the basis of harmine chemical structure. Cytotoxic activities of these compounds were investigated in vitro. The results showed that some beta-carboline derivatives had significant cytotoxic activities against human tumor cell lines. Among all the synthesized beta-carboline derivatives, the compounds 27, 28 and 32, having a benzyl substituent at both position-2 and 9, respectively, were found to be the most potent compounds with IC50 value lower than 50 mu M against all human tumor cell lines examined. Acute toxicities and antitumor activities of the selected beta-carboline derivatives in mice were also evaluated. The results demonstrated that a benzyl substituent at position-2 increased the antitumor activity as well as acute toxicity significantly. However an (ethoxycarbonyl)amino substituent at position-3 reduced the acute toxicity as well as antitumor activity remarkedly. These data suggested that (1) the antitumor potencies of beta-carboline derivatives were enhanced by the introduction of benzyl substituent into the position-2; (2) the acute toxicity of beta-carboline derivatives reduced dramatically by the introduction of an appropriate substituent into the position-3 and 9; (3) the beta-carboline structure might be an important basis for the design and synthesis of new antitumor drugs with significant antitumor activity and low toxicity.
