Anicequol (developmental code names NGA0187, NGD-187)^[1] is a naturally occurring ergostane steroid produced by Acremonium sp. TF-0356 which has nerve growth factor-like neurotrophic activity.^[2]^[3]^[4] It was under investigation by Taisho Pharmaceutical in Japan for the treatment of cognitive disorders in the 1990s, but development was discontinued and the drug was never marketed.^[5]
