Synthesis and antibacterial activity of aromatic and heteroaromatic amino alcohols

de Almeida, Camila G.,Reis, Samira G.,de Almeida, Angelina M.,Diniz, Claudio G.,da Silva, Vania L.,Le Hyaric, Mireille

experimental part, p. 876 - 880 (2012/06/18)

Two series of aromatic and heteroaromatic amino alcohols were synthesized from alcohols and aldehydes and evaluated for their antibacterial activities. All the octylated compounds displayed a better activity against the four bacteria tested when evaluated by the agar diffusion method and were selected for the evaluation of minimal inhibitory concentration. The best results were obtained for p-octyloxybenzyl derivatives against Staphylococcus epidermidis (minimal inhibitory concentrations = 32μm).
