Niacinamide transport through the blood-brain barrier

Authors: Reynold Spector;

Niacinamide transport through the blood-brain barrier

Abstract

The unidirectional influx of niacinamide across cerebral capillaries, the anatomical locus of the blood-brain barrier, was measured with an in situ rat brain perfusion technique employing [14C]niacinamide. Niacinamide was transported rapidly across the blood-brain barrier by a system that was not saturable with 10 mM niacinamide in the perfusate. However, with periods of perfusion longer than 30 seconds, there was substantial backflow of [14C]niacinamide into the perfusate. Niacinamide (1.7 microM) transport through the blood-brain barrier was not significantly inhibited by 3-acetylpyridine. Thus, niacinamide is transported rapidly and bidirectionally through the blood-brain barrier by a high capacity transport system. Although involved in the transfer of niacinamide between blood and brain, this transport system does not play an important regulatory role in the synthesis of NMN, NAD, and NADP from niacinamide in brain.
