Correlation of chemical structure with reproductive and developmental toxicity as it relates to the use of the threshold of toxicological concern

Bixa orellana L., popularly known as “urucum,” has been used by indigenous communities in Brazil and other tropical countries for several biological applications, which indicates its potential use as an active ingredient in pharmaceutical products. The aim of this work was to report the main evidence found in the literature, concerning the ethnopharmacology, the biological activity, and the phytochemistry studies related to Bixa orellana L. Therefore, this work comprises a systematic review about the use of Bixa orellana in the American continent and analysis of the data collected. This study shows the well-characterized pharmacological actions that may be considered relevant for the future development of an innovative therapeutic agent.

Traditional Uses, Chemical Constituents, and Biological Activities of Bixa orellana L.: A Review

Antibacterial activities of medicinal plants used in Mexican traditional medicine.

Vitamin E was first discovered in 1922 as a substance necessary for reproduction. Following this discovery, vitamin E was extensively studied, and it has become widely known as a powerful lipid-soluble antioxidant. There has been increasing interest in the role of vitamin E as an antioxidant, as it has been discovered to lower body cholesterol levels and act as an anticancer agent. Numerous studies have reported that vitamin E exhibits anti-proliferative, anti-survival, pro-apoptotic, and anti-angiogenic effects in cancer, as well as anti-inflammatory activities. There are various reports on the benefits of vitamin E on health in general. However, despite it being initially discovered as a vitamin necessary for reproduction, to date, studies relating to its effects in this area are lacking. Hence, this paper was written with the intention of providing a review of the known roles of vitamin E as an antioxidant in female reproductive health.

Vitamin E as an Antioxidant in Female Reproductive Health

Carotenoids are regarded as effective antioxidants, antimutagenic and anticarcinogenic agents. Annatto, a red-yellow extract obtained from seeds of Bixa orellana L. is a mixture of several carotenoids and one of them bixin (BXN), is known as its major coloring compound. Studies on BXN clastogenicity and anticlastogenicity in cultured human lymphocytes have not been reported so far. Therefore, the present study was undertaken to investigate the ability of BXN to induce chromosomal aberrations in human lymphocytes in vitro and to examine the possible anticlastogenic effect of this carotenoid in chromosomal damage induced by the clastogen cisplatin (cDDP). Human blood samples were obtained from six healthy, non-smoking volunteers; two females and four males aged 18–35 years. The concentrations of BXN (1.0; 2.5; 5.0 or 10 μg/mL) tested in combination with cDDP were established on the basis of mitotic index (MI) measurements. The data showed that BXN was not cytotoxic or clastogenic, when compared to untreated control. A marked decrease in the MI values compared to the untreated control and an increased percentage of aberrant metaphases was seen in all cultures treated with cDDP. The carotenoid efficiency in reducing the inhibitory effect of cDDP on lymphocyte MI is concentration-dependent. Cultures simultaneously treated with BXN and cDDP showed a statistically significant reduction in total chromosomal aberrations and aberrant metaphases. In our experiments, BXN may have acted as an antioxidant by intercepting free radicals generated by cDDP. The data obtained in the present study suggest that dietary carotenoids may act as protective agents against clastogenic effects of antitumor agents. However, extensive studies are necessary to elucidate the mechanism of action of BXN before its therapeutic use.
