Abstract: We report for the first time that pterostilbene, a natural analog of resveratrol, shows anxiolytic-like action by downregulating phosphorylated levels of ERKs in the hippocampus of mice. Mice administered pterostilbene (1-10 mg/kg BW) by oral gavage were subjected to the Elevated-plus maze (EPM) test. Pterostilbene manifested anxiolytic activity at 1 and 2 mg/kg doses, demonstrated by an increase in percent permanence time and number of entries in open arms, critical determinants correlated with anxiety. This anxiolytic activity of pterostilbene was comparable to that of diazepam at 1 and 2 mg/kg in the EPM. The percent traveled distance and the percent permanence time in the enclosed arms were decreased with the 1 and 2 mg/kg doses. The 5 and 10 mg/kg doses did not show any anxiolytic effect. Locomotor activity was unaffected in all doses.

Abstract: The sponges were collected from a variety of locations in the Florida Keys and separated based on morphology and color. The samples were identified as three species, two of which are well known: V. rigida (Esper, 1794) (order Verongida, family Aplysinidae) and S. aurea (Hyatt, 1875) (order Dictyoceratida, family Thorectidae), and a third S. cerebriformis (Duchassaing & Michelotti, 1864), is less common and separated based on subtle differences of morphology and coloration, from the other two species. Several compounds were isolated and were evaluated in established animal models predictive of neurological related drug function, namely, the rodent FST and the chick anxiety-depression model.
