The University of Hawaii at Manoa received a $156,500 Project Grant from the National Institute of Child Health and Human Development (NICHD) under the Child Health and Human Development Extramural Research program (CFDA 93.865), awarded September 26, 2025, with completion targeted for August 31, 2027. The project develops and applies pluripotent stem cell-based new approach methodologies (NAMs) to evaluate the reproductive and teratogenic risks of memory-enhancing dietary supplements, particularly vinpocetine. The research deliverables include characterization of vinpocetine's molecular impacts through whole-genome transcriptomic analyses and bioinformatic pathway identification; identification of specific molecular targets responsible for teratogenicity using loss-of-function studies; and assessment of alternative memory-enhancing supplements to address consumer safety concerns as regulatory warnings limit vinpocetine availability.
This project addresses a regulatory gap in the reproductive safety evaluation of dietary supplements by generating human-relevant developmental toxicity data using mouse and human stem cell models that recapitulate embryonic morphogenesis processes. The research outcomes will provide the scientific basis for FDA and consumers to evaluate the teratogenic potential of vinpocetine and related compounds, supporting evidence-based supplement safety assessments where animal study data alone have proven insufficient for human risk characterization.
