title: Synthesis of 7 alpha- and 7 beta-spermidinylcholesterol, squalamine analogues.
abstract: Stereoselective synthesis of squalamine dessulfates analogues, 7 alpha and 7 beta-N-[3N-(4-aminobutyl) aminopropyl]aminocholesterol are reported, using 7 alpha and 7 beta-aminocholesterol as a key intermediate. It's the first example in which the position of spermidine is modified at the steroid ring. These molecules showed a comparable antibacteria and fungi activities to squalamine. Then, they have a cytotoxic activity on a human non-small cell bronchopulmonary carcinoma line (NSCLC-N6).
