摘要:
The cationic lipid pcTG90 has been prepared from (S)-1-aminopropane-2,3-diol by N-acylation with N-protected 18-amino-3,7,11,15-tetraazaoctadecanoic acid and O-acylation with oleic acid. The former acid could be obtained from 1,3-propanediamine via tetraprotected caldopentamine. The stability of the cationic lipid in HEPES buffer has been studied. (C) 1999 Elsevier Science Ltd.
