the 1,4-dihydropyridine (dhp) derivatives are a known class of calcium channel blockers. some derivatives of dhp showed significant cytotoxicity. it was shown that this effect may not be the result of interaction with ca2+ channels. in this study, we performed an investigation about the intrinsic cytotoxicity of some derivatives of dhp containing nitroimidazole moiety on their c4 position on fo...

abstractferulago angulata boiss. known in iran as chavir, has some bioactive compounds having antioxidant activity. because of its antioxidant activities, it sounded chavir extract can be a good candidate for finding chemopreventive agents having inductive apoptosis properties on cancer cells. in this study, the cytotoxic effects and proapoptotic activities of chavir’s leaf and flower extracts ...

phytochemical investigations of piper sarmentosum roxb., yielded four compounds; three amides, identified as 3-(3’,4’,5’-trimethoxyphenylpropanoyl) pyrrolidine, 3-(4’-methoxyphenylpropanoyl) pyrrole, n -(3-phenylpropanoyl) pyrrole and a sterol namely β -sitosterol . 3-(4’-methoxyphenylpropanoyl) pyrrole was found for the first time in this piper species. all chemical constituents were tested fo...

Although Ginsenosides are a major physiological component of red ginseng (RG), some isolated ginsenosides known to have cytotoxic activity. This study was intended reduce cytotoxicity and promote anti-inflammatory activity by mixing the crude (RG-CG) polysaccharides (RG-CP). RG-CG-CM, fractionated from RG-CG, not only had higher than that RG-CG at 100 μg/mL, but also showed increased cytotoxici...

dacarbazine is an antitumor prodrug which is used for the treatment of malignant metastatic melanoma and hodgkin’s disease. it requires initial activation in liver through an n-demethylationreaction. the active metabolite prevents the progress of disease via alkylation of guanine bases in dna strands. in order to investigate the importance of imidazole ring and its dynamictautomerization in ant...

Keywords: N-(5-methyl-[1,3,4]thiadiazol-2-yl)-propionamide, cytotoxicity in vitro, anticancer activity

cancer is a group of diseases characterized by uncontrolled proliferation of abnormal cells. because of the severe side effects and resistance to the traditional chemotherapeutic agents, the necessity for discovery of new anticancer drugs is a crucial topic. in the present study we synthesized new derivatives of 2-(4-fluorophenyl)- n -halophenylacetamide and assessed their cytotoxicity against ...
