Pantoyl-taurine

Bacterial inhibition by metabolites analogs pantoyl taurine. Brit. J... 

Since the antibiotin factor does not inhibit those bacteria which synthesize biotin, the antibiotin factor appears to combine only with the externally supplied biotin and cannot penetrate effectively to the sites of biotin synthesis and utilization. This is analogous to the findings with the synthetic inhibitory growth factor analogs (e.g., pyrithiamin and thiamin, pantoyl taurine and pantothenic acid, pyridine-2-sulfonamide and nicotinamide) where the inhibitory action is largely confined to those otgan-isms which do not synthesize the growth factor.
