Calmodulin inhibitors were found in the bitter poisonous mushroom Naematoloma fasciculare (Fr.) KARST. (Strophariaceae). The active compounds, fasciculols B, C, and F, were isolated by droplet counter-current chromatography and identified on the basis of various physical and spectral data. Application of the dibenzoate chirality method to a p-bromobenzoate derivative of fasciculol C allowed the absolute configurations at the C-2 and C-3 positions to be determined as (R) and (S), respectively.
