PhI(OAc)<sub>2</sub>-mediated one-pot oxidative decarboxylation and aromatization of tetrahydro-β-carbolines: synthesis of norharmane, harmane, eudistomin U and eudistomin I
A new strategy for synthesis of β-carbolines via one-pot oxidative decarboxylation at room temperature is developed for the first time.
首次开发了一种在室温下通过一锅法氧化脱羧合成β-咔啉的新策略。
Design and synthesis of β-carboline linked aryl sulfonyl piperazine derivatives: DNA topoisomerase II inhibition with DNA binding and apoptosis inducing ability
A series of new β-carboline linked aryl sulfonylpiperazine congeners have been synthesized by coupling various β-carboline acids with substituted aryl sulfonylpiperazines. Evaluation of their anticancer activity against a panel of human cancer cell lines such as colon (HT-29), breast (MDA-MB-231), bone osteosarcoma (MG-63), brain (U87 MG), prostate (PC- 3) and normal monkey kidney (Vero) cell line
Design and synthesis of dithiocarbamate linked β-carboline derivatives: DNA topoisomerase II inhibition with DNA binding and apoptosis inducing ability
Further, the induction of apoptosis by these derivatives was confirmed by Annexin V-FITC and Hoechst staining assays. However, both biophysical as well as molecular docking studies suggested a combilexin-type of interaction between these derivatives and DNA, unlike simple β-carbolines. With a view to understand their mechanism of action, DNA topoisomerase II (topo II) inhibition assay was also performed.
A series of new podophyllotoxin linked β-carboline congeners have been synthesized by coupling various substituted β-carboline acids with 4β-aminopodophyllotoxin. Evaluation of their anticancer activity against a panel of human cancer cell lines such as lung cancer (A549), prostate cancer (DU-145), MDA MB-231 (breast cancer), HT-29 (colon cancer) and HeLa (cervical cancer) suggested that 7i and 7j
Design and synthesis of thiadiazolo-carboxamide bridged β-carboline-indole hybrids: DNA intercalative topo-IIα inhibition with promising antiproliferative activity
impressive cytotoxicity against A549 cell line (IC50: 3.00 ± 1.40 μM). Further target-based assay of these two compounds 12c and 12a revealed their potential as DNAintercalative topoisomerase-IIα inhibitors. Additionally, the antiproliferative activity of compound 12c was measured in A549 cells by traditional apoptosis assays revealing the nuclear, morphological alterations, and depolarization of membrane
