sym-Homospermidine
sym-Homospermidine is a triamine polyamine and a structural analog of spermidine derived from plants. sym-Homospermidine can be taken up by bacteria and promotes the growth of Spe auxotrophic strains of Escherichia coli without inhibiting the growth of wild-type strains. sym-Homospermidine can be used in Escherichia coli-related research.

Biological Activity
sym-Homospermidine (100 μM) does not support growth of spermidine-auxotrophic Agrobacterium tumefaciens ΔCASDH and ΔCASDC strains when supplied at 100 μM in chemically defined medium[1].
sym-Homospermidine (0.125-12.5 μg/mL; over at least a ten-fold increase in cell density or after growth to A450 of 0.095 to 0.105) is taken up efficiently by Escherichia coli spermidine auxotrophs DR112 and EWH319 and wild-type strain 3000, stimulates growth of EWH319 with similar efficacy to spermidine at comparable intracellular levels, but is far less effective at stimulating growth of DR112 even at three-fold higher intracellular levels, and does not inhibit growth of wild-type E. coli[2].
