Some biological properties of thiaminic acid and O-benzoylthiaminic acid were investigated. When orally administered, the thiaminic acids had no effect on survival time of thiamine deficient love birds (Uroloncha domestica), showing no thiamine activity. However, these compounds had no action of anti-thiamine even when they were administered equivalent to 600 μg thiamine hydrochloride a day, with or without 3μg of thiamine hydrochloride. The acute toxicity for mice by intravenous injection was much lower than those of known thiamine related compounds.
