A series of derivatives of dihydrofuran-2(3H)-one (gamma-butyrolactone, GBL) was synthesized and tested for anticonvulsant, neurotoxic and analgesic activity. In the anticonvulsant screening 10 lactones were effective in the maximal electroshock test (MES) at the highest doses (300 and 100 mg/kg, 0.5 h, ip, mice). Statistical analysis showed correlation between the anticonvulsant activity and relative lipophilicity parameters determined by experimental and computational methods (R-M0, ClogP and M log P). Preliminary antinociceptive evaluation of selected derivatives revealed strong analgesic activity. The majority of the tested compounds showed high efficacy in animal models of acute pain (hot plate and writhing tests) and strong local anesthetic activity (modified tail immersion test). The obtained ED50 values were comparable with such analgesics as acetylsalicylic acid and morphine. (C) 2012 Elsevier Ltd. All rights reserved.

Die Umsetzung entsprechender α‐Amino‐γ‐lactone mit Phenyllithium führt zu den 2‐Amino‐1,1‐diphenyl‐alkan‐1,4‐diolen 2a–f, die auch als dihydroxylierte Diphenylethylamine aufgefaßt werden können.
