Background: ß-carbolines, harmaline and harmine, are the major alkaloids presenting in the seeds of the Peganum harmala L. These alkaloids are known as herbal active principals with potential use in pharmaceutical and medicine. Objectives: To assess the growth inhibitory effect of phyto-alkaloids, harmaline and harmine, on cancer cell lines. Method...

Background: Both mitochondrial dysfunction and aerobic glycolysis are signs of growing aggressive cancer. If altered metabolism of cancer cell is intended, using the glycolysis inhibitor (2-deoxyglucose (2DG)) would be a viable therapeutic method. The AMP-activated protein kinase (AMPK), as a metabolic sensor, could be activated with metformin and it can also launch a p53-dependent metabolic ch...

a new series of n-(5-mercapto-1,3,4-thiadiazol-2-yl)-2-phenylacetamide derivatives (3a-3j) were synthesized via an amidation reaction using edc and hobt in acetonitrile solvent at room temperature condition. chemical structures were characterized by 1h nmr, ir and ms spectroscopic methods and related melting points were also determined. the anticancer activity was evaluated using mtt procedure ...

Background and Purpose: Patulin is a mycotoxin produced by some molds,especially Aspergillus and Penicilium, and is responsible for mycotoxicosis in animals and humans.There is still not very detailed data about the anti-cancer potency of patulin, but some reports demonstrated that it induces cellular apoptosis and toxicity. Materials and Methods: To determine the efficacy of patulin as a ther...

Background: Breast cancer is the most common female malignancy and the leading cause of cancer mortality in women worldwide. The human epidermal growth factor receptor2 (HER2) is a transmembrane tyrosine kinase receptor that is usually overexpressed in human breast cancers. Stable cell lines heterogeneously overexpressing HER2 are highly required as in vitro models for breast cancer research. T...

Background: Cancer refers to the abnormal growth of cells and is still the most common cause of morbidity in world. The purpose of this study was to determine cytotoxicity effect of high molecular weight (HMWC) and low molecular weight of chitosan (LMWC) on three cancerous cell lines MCF-7, HeLa and Saos-2 with different histological origin. Methods: The anticancer property of two types of chi...

cancer cell-stromal cell interaction plays a crucial role in the growth and invasion of tumor cells of various organs. it has been recently suggested that adipocytes and preadipocytes, two specific types of stromal cells, affect the biological behavior of variety of breast cancer cell lines. in spite of few investigations, there is a controversy in the literatures about the effects of adipocyte...

Cancer is a big global problem and is one of the top and main causes of mortality in developed countries. Many of the current treatments and anticancer therapeutics have problems with severe side effects and on the other hand, the drug resistance is also another obstacle in the cancer chemotherapy. Hence, there is a strong demand for the discovery and development of effective new antineopla...

background: during the past few years, hesa-a, a herbal-marine mixture, has been used to treat cancer as an alternative medicine in iran. however, weight of the evidence is not sufficient to accept or refuse the use of this compound as a cytotoxic drug. we investigated the selective anticancer effects of hesa-a on breast, prostate, colon, and glioblastoma multiforme (gbm) neoplastic cell lines....
