Small Molecule Modulators of Lithium for Treatment of Fragile X Syndrome

With a $219,500 grant from FRAXA Research Foundation, Dr. Stephen Haggarty from Havard/MIT developed a high-throughput drug screen to find compounds that inhibit GSK3, a critical enzyme in fragile X. He looked for compounds that can accomplish this either alone or in combination with lithium, offering the possibility of enhancing the effectiveness of lithium as a treatment. His drug screen used patient-specific neural progenitor (NP) cells derived from human induced pluripotent stem cells (iPSCs) – which are created from cells in a skin biopsy from people with fragile X syndrome (FXS) and other autism spectrum disorders.
