摘要:
Following the promising activity of Q(2)FA15 on axonal growth, two new series of N/O-substituted QFAs were synthesized, based on a S(N)2-type reaction. O-alkylated QFA bearing 14 carbon atoms on the side chain (n = 14) shows a very potent activity on axonal growth though lowered when compared to Q(2)FA15. While O-alkylation allows good retention of the biological activity, N-alkylation abolishes it nonetheless. A solid-phase-supported synthesis of Q(2)FA15 allowing the conception of new hybrid compounds is also described. (c) 2006 Elsevier Ltd. All rights reserved.
