In vitro and histological investigation of antitumor effect of some triazole compounds in colon cancer cell line

1,2,4-Triazoles are used as antifungal, antibacterial, antimicrobial, and antioxidant against some oxidative radical species. Recently, many 1,2,4-triazoles continue to be synthesized. In this study, the effect of the 1,2,4-triazole derivatives on human colon cancer (HT29) was investigated in vitro and in vivo in rats. MTT test was applied to in in vitro experiments. For in vivo study, rats were divided into seven groups as follows: Control group (negative control), azoxymethane (AOM), AOM + cisplatin 15, AOM + L1, AOM + L2, AOM + L3, and AOM + L4. To create colon cancer, the AOM injection was injected subcutaneously at a dose of 15 mg/kg, three times (once weekly). The in vivo studies were completed at 28 weeks. It was found that the 1,2,4-triazole derivatives reduced the cell viability (P < 0.05). In all animals in the experimental groups, mild dysplasia was detected in 100% of the colon mucosal epithelium. Severe dysplasia and adenocarcinoma were observed in L1 groups. As a result, this study determined that the 1,2,4-triazole derivatives exhibit antitumor activity.

This review discusses the development of studies that evaluated the essentiality and requirements of iron from the ancient to the present. The therapeutic effects of iron compounds were recognized by the ancient Greeks and Romans. The earliest recognition of the essentiality of iron was stated by Paracelsus, a distinguished physician alchemist, in the sixteenth century. Iron was included in the earliest nutritional standard prepared for the Royal Army by E. A. Parkes, the first professor of hygiene. The League of Nations Health Organisation determined average iron requirements based on literature review. In the first US Recommended Dietary Allowances (RDA), the RDA of iron was determined from the results of iron balance studies. In the current Dietary Reference Intakes, iron requirements were determined based on the factorial method with the aid of Monte Carlo simulation for combining basal and menstrual iron losses. Population data analysis is a recently developed alternative that does not use the pre-estimated iron absorption rate and requires the prevalence of inadequacy instead. Population data analysis uses the convolution integral for combining basal and menstrual iron losses to ensure the required accuracy. This review also provides new estimates of hair and nail iron losses.
