摘要:
The invention relates to α-galactoceramide analogs, their methods of manufacture, intermediate compounds useful in these methods. It also relates to pharmaceutical compositions containing the α-galactoceramide analogs. The methods of manufacture of the invention involve the use of unsaturated intermediate compounds which enable to synthesize α-galactoceramide analogs by a mere metathesis reaction. The α-galactoceramide analogs of the invention are useful as active ingredients of pharmaceutical compositions, particularly in pharmaceutical compositions having anti-cancerous properties.
