Synthesis of neuroprotective cyclopentenone prostaglandin analogs: Suppression of manganese-induced apoptosis of PC12 cells
摘要:
The synthesis and evaluation for anti- and proapoptotic properties of cyclopenterione prostaglandin analogs are described. Novel J-type analogs of NEPP11 with a cross-conjugated cyclopentadienone moiety and a lipophilic omega-side chain suppressed manganese ion-induced apoptosis of PC12 cells at comparable levels to NEPP11, while monoenone derivatives were inactive. The proapoptotic activities of J-type analogs were much lower than that of NEPP11. Natural 15-deoxy-Delta(12,14)-PGJ(2) and Delta(7)-PGA(1) methyl ester were highly toxic, inducing apoptosis at lower concentrations. (C) 2006 Elsevier Ltd. All rights reserved.
