A series of glycitylamines, which were prepared in few steps from readily available carbohydrates, were tested for their ability to inhibit tuberculosis growth in an Alamar Blue BCG colourimetric assay. Several derivatives, including (2R, 3R)-1-(hexadecylamine)pent-4-ene-2,3-diol, (2R, 3R)-1-(hexadecylmethylamino)pent-4-ene-2,3-diol and 5-deoxy-5-hexadecylmethylamino-D-arabinitol, were prepared in good to excellent (44-90%) overall yield and exhibited micromolar (20-41 mu M) inhibitory activity that was similar to the first line tuberculosis (TB) drug ethambutol (39 mu M) in the same assay. The ease and low cost of the synthesis of the glycitylamines offers definite advantages for their use as potential TB drugs. (c) 2016 Elsevier Ltd. All rights reserved.

was modest, several of the amines, including d-arabinitylamine 1a and d-fucitylamine 1g, exhibited low micromolar IC50 values for HL60 cells. Moreover, these two amines showed good selectivity towards HL60 cells when compared to non-cancerous HEK-293 cells. The compounds also showed low micromolar inhibition of the leukaemic cell line, THP-1. The modes of action of amines 1a and 1g were then determined
