carbazole/breast neoplasms

Chemotherapeutics used in cancer treatment may elicit pleiotropic effects interfering, for instance, directly on DNA metabolism or on endoplasmic organelles functions. Recently there has been a trend towards the use of molecular-targeted therapies as alternative treatments of cancer, arising from

The objective of this study was to explore whether the conversion of the 2-phenylindole system into the tetracyclic benzo[a]carbazole changes the endocrine profile when the side chain structure was kept constant. Five different sulfur-containing side chains were linked to the nitrogen of the

The current optimization of IG-105 (3) on the carbazole-ring provided a series of new carbazole sulfonamides derivatives 13a-13m. All of the compounds have been evaluated against HepG2 cells (hepatoma cancer) for antiproliferative activity. Compounds that showed activity better or comparable to that

The carbazole ligand 3 was synthesized, characterized and its binding interactions with human telomeric (22HT) G-quadruplex DNA in Na⁺ and K⁺-containing buffer were investigated by ultraviolet-visible (UV-Vis) spectrophotometry, fluorescence, circular dichroism (CD) spectroscopy, and DNA

A series of unknown 3-(alkyl(dialkyl)amino)benzofuro[2,3-f]quinazolin-1(2H)-ones 4-17 has been synthesized as new ellipticine analogs, in which the carbazole moiety and the pyridine ring were replaced by a dibenzofuran residue and a pyrimidine ring, respectively. The synthesis of these

Two recently synthesized, trisubstituted dihydrobenzo(a)carbazoles were investigated regarding their anti-HIV and antitumoral activity. The compounds showed some activity against melanoma, renal cancer and breast cancer cell lines.

A number of 11-alkylbenzo[a]carbazoles and their 5,6-dihydro derivatives with one or two hydroxy groups in the aromatic rings were synthesized and studied for their binding affinities for the estrogen receptor. Best conditions for the receptor binding are provided by one hydroxy group at C-3 and a

For a newly synthesized compound, identifying its target protein is a slow but pivotal step toward understand its pharmacologic mechanism. In this study, we systemically synthesized novel manzamine derivatives and chose 1-(9'-methyl-3'-carbazole)-3, 4-dihydro-β-carboline (MCDC) as an example to

Estrogens control a wide number of aspects of human physiology and play a key role in multiple diseases, including cancer. Estrogens act by binding to and activating the cognate receptor (ER), however numerous studies have revealed that the G protein-coupled receptor named GPR30/GPER mediates also

BACKGROUND Indole-3-carbinol (I3C) and related compounds have been identified in vegetables of the Brassica genus. I3C and its acid-derived condensation product, indolo[3,2-b]carbazole (ICZ), bind to the aryl hydrocarbon (Ah) receptor and induce CYP1A1/1A2 gene expression in both in vivo and in

A causal link between overexpression of aryl hydrocarbon receptor (AHR) and its target cytochrome P450 1A1 (CYP1A1) and metastatic outgrowth of various cancer entities has been established. Nevertheless, the mechanism how AHR/CYP1A1 support metastasis formation is still little understood. In vitro

This paper deals with the characterization and aryl hydrocarbon receptor (AhR) agonist activities of a series of chlorinated, brominated, and mixed bromo/chlorocarbazoles, some of which have been identified in various environmental samples. Attention is directed here to the possibility that

Naphtho[2,1-α]pyrrolo[3,4-c]carbazole-5,7(6H,12H)-dione (NPCD) is known to be a very potent and selective cyclin D1-CDK4 inhibitors and could induce strong G1 phase arrest in breast tumor cell lines. In this work, the synthesis of five NPCD glycosides and their cytotoxic activities against eight

Based on the efficacy of EHop-016 as an inhibitor of migration and Rac1 activation, a new series of carbazole derivatives has been synthesized. Cytotoxic and anti-migratory effects of these compounds were evaluated in MCF-7 and MDA-MB-231 breast cancer cell lines. Preliminary investigations of their

Carbazole derivatives show anti-cancer activity and are of great interest for drug development. In this study, we synthesized and analyzed several new alkylamide derivatives of racemocin B, a natural indolo[3,2-a]carbazole molecule originally isolated from the green alga Caulerpa racemose. Several
