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...
Numerous studies have been focused on natural anticarcinogenic agents. Many antioxidants have been identified as anticarcinogens. Antimutagens have also been proposed as cancer chemopreventive agents. The use of natural products as anticancer has a long history that began with traditional medicine. The aim of this study was to evaluate cytotoxicity and antioxidant activity of twenty-three plant...
جهت بهینه سازی شرایط تولید پروتئین هیدرولیز شده (شامل نسبت آنزیم به سوبسترا، دما و زمان) به منظور دستیابی به بالاترین خواص آنتی اکسیدانی، مینس تهیه شده از ضایعات میگوی ببری سبز (penaeus semisulcatus) پس از تعیین درصد پروتئین آن (13%، بر اساس وزن تر) با استفاده از دو پروتئاز تجاری آلکالاز و فلاورزایم بر اساس 18 تیمار تعیین شده با طرح آزمایشات سطح پاسخ برای هر آنزیم، هیدرولیز شده و با خشک کن انجم...

The cytotoxicity of a high purity Cornish kaolinite toward mouse peritoneal macrophages in vitro was examined. The material was cytotoxic towards these cells, the activity could be decreased substantially by pretreating the dust with poly(2-vinylpyridine N-oxide). Pretreatment of the dusts with poly(acrylic acid) had a small effect on cytotoxicity, but combinations of the polymer treatments vir...
Graph theory had wide applications in developing silico tools and it is widely used to calculate topological indices establish structural activity relations of chemicals/compounds. However, usage Zagreb with respect natural compounds activity/toxicity prediction needs more attention. Many available online are using atom bond connectivity index (ABC Index), first second indices. The the Hyper ve...
Ribonuclease (RNase) A can be endowed with cytotoxic activity by enabling it to evade the cytosolic ribonuclease inhibitor protein (RI). Enhancing its conformational stability can increase further its cytotoxicity. Herein, the A4C/K41R/G88R/V118C variant of RNase A was created to integrate four individual changes that greatly decrease RI affinity (K41R/G88R) and increase conformational stabilit...
