An in vitro model of acquired melphalan resistance was developed by serial incubation of an MCF-7 human breast cancer cell line in increasing concentrations of melphalan. The resulting derivative cell line, Me1R MCF-7, was 30-fold resistant to melphalan. Uptake studies demonstrated decreased initial
Identification of a new class of antitumor agent capable to induce apoptosis without triggering necrotic cell death event is challenging. The present communication describes the multicomponent synthesis of seven new (1S,4S)-2,5-diazabicyclo[2.2.1]heptane-dithiocarbamates and their in vitro
OBJECTIVE
L-type amino acid transporter 1 (LAT1) is essential for the transport of large neutral amino acids. However, its role in breast cancer growth remains largely unknown. The purpose of the study is to investigate whether LAT1 is a potential biomarker for the diagnosis and treatment of breast
The synthesis of 3-(cyclohexymethyl)-1-(4-aminophenyl)-3-azabicyclo[3.1.0]hexane-2, 4-dione (1h), with its optical enantiomers, and a series of novel achiral 1-(4-aminophenyl)-3-azabicyclo[3.1.1]haptane-2,4-diones (2a-i,k) is described. These compounds were tested in vitro for inhibition of human
Three extracts of Calendulae officinalis flos (Asteraceae): heptane, ethyl acetate and methanol were introduced to a human skin fibroblast (HSF) cells culture and a culture of human breast cancer cells (T47D), cell culture collection ECACC number 85102201. The ethyl acetate but not the heptane and
Over the years, ionic liquids (ILs) have gained tremendous importance because of their unique properties and plethora of applications. In this work, we have developed a new nanoscale hybrid gel consisting of 1-ethyl-3-methylimidazolium dimethyl phosphate, [C2mim][dmp], and self-assembled
Estrogen receptors (ERs) play a major role in the growth of human breast cancer cells. A selective estrogen receptor down-regulator (SERD) that acts as not only an inhibitor of ligand binding, but also induces the down-regulation of ER, would be useful for the treatment for ER-positive breast
Compounds that block estrogen action through the estrogen receptor (ER) or downregulate ER levels are useful for the treatment of breast cancer and endocrine disorders. In our search for structurally novel estrogens having three-dimensional core scaffolds, we found some compounds with a
In human tumor cells freshly obtained from patients with breast cancer, ovarian cancer, or adenocarcinoma of unknown etiology and in normal human bone marrow cells, the cell-to-medium ratio (intracellular/extracellular concentration) in vitro of 5.42 microM melphalan rose rapidly to levels of 6-17
The anti-cancer therapeutic promise of cantharidin is limited because of its high mammalian toxicity. In order to find new anti-cancer lead compounds with reduced toxicity of the cantharidin prototype, the following seven derivatives were screened against the human SH-SY5Y neuroblastoma and MCF-7
The lipophilic anticancer drug prednimustine was incorporated into model low-density-lipoprotein (m-LDL) using a novel modified method. The major steps of this procedure involve the preparation of a microemulsion containing the drug and the complexing of this emulsion with apolipoprotein B (apo B)
The increasing rate of cancer incidence has encouraged the search for novel natural sources of anticancer compounds. The presence of small quantities of taxol and taxanes in Corylus avellana L. has impelled new potential applications for this plant in the field of biomedicine. In the present work,
