A series of 3-amino and polyaminosterol analogues of squalamine and trodusquemine were synthesized involving a new stereoselective titanium reductive amination reaction in high chemical yields of up to 95% in numerous cases. These derivatives were evaluated for their in vitro antimicrobial properties against human pathogens. Activity was highly dependent on the different compounds' structures involved and best results have been obtained with aminosterol derivatives 4b, 4e and 6i exhibiting activities against yeasts, Gram positive and Gram negative bacteria at average concentrations of 6.25-12.5 mu g/mL.
