S03-01 An emerging toolbox for Botanical risk assessment
The HESI Developmental and Reproductive Toxicology (DART) Working Group of the Botanical Safety Consortium is dedicated to developing reliable screening strategies to identify botanicals with potential developmental or reproductive toxicity. Our mission encompasses the selection of in silico and in vitro tools capable of accommodating the complex mixtures inherent in botanicals, as well as the evaluation of candidate botanicals based on suspected DART endpoints. We have established a series of botanical case studies to assess the efficacy of a NAM toolbox based on functional as well mechanistic assays.
In our recent evaluations, we identified several botanicals that have been studied for DART effects. Blue cohosh (Caulophyllum thalictroides), traditionally used to induce labour, was associated with fetal bovine cardiac defects. Usnea Lichen affected estrous cycling in a 90-day rodent study, and usnic acid demonstrated teratogenic effects in rats and zebrafish. Conversely, ashwagandha, Asian ginseng, and milk thistle are not expected to cause DART effects.
Selected assays, such as Devtox Quick Predict and transcriptional profiling with Connectivity Mapping, were employed to explore their utility in identifying DART-relevant botanicals. Notably, the Devtox assay revealed significant changes in cystine and ornithine metabolism for blue cohosh and usnea lichen, indicating a high potential for developmental toxicity. Ginseng showed changes in cystine metabolism alone, and no response was detected with ashwagandha. Although milk thistle exhibited changes in both metabolites, these occurred at concentrations affecting cell viability. Connectivity Mapping (CMap) analysis linked blue cohosh to compounds like GABA receptor antagonists, acetylcholinesterase inhibitors, and mycophenolic acid, all of which are associated with adverse reproductive outcomes. Ginseng connections included ginsenosides and various agents with potential stimulating and hormonal effects.
The data generated from this research will be made publicly available via the NIEHS database. As we continue, we aim to refine our data analysis and expand our assays and botanical repertoire to enhance safety decision-making processes in botanical evaluation.
