The synthesis of heterocyclic analogues of the platelet activating factor is described. The preparation starts with acylating rac-tetrahydro-1,3-thiazine-4-carboxylic acid ethyl ester, with palmitoyl chloride to form the amide linkage. Following ester reduction, the phosphocholine part is introduced via 2-chloro-2-oxo-1,3,2-dioxaphospholane and subsequent ring opening with trimethylamine under pressure

The synthesis of ten proline-modified analogues of the neuroprotective tripeptide GPE is described. Five of the analogues incorporate a proline residue with a hydrophobic group at C-2 and two further analogues have this side chain locked into a spirolactam ring system. The pyrrolidine ring was also modified by replacing the gamma-CH2 group with sulfur and/or incorporation of two methyl groups at C-5. (c) 2005 Elsevier Ltd. All rights reserved.

Thiazolidine and pyrrolidine compounds containing a thiourea moiety were prepared using boric acid as a coupling agent in a multicomponent methodology. In addition, the antioxidant activity, as reflected by free radical scavenging, was evaluated. Some compounds were selected and tested in different antioxidant experiments and all of them were shown to be useful for the prevention of oxidative stress in biological systems and thus capable of reducing cellular injury.
