D-Arabinose-d5 is the deuterium labeled D-Arabinose (HY-N0059). D-Arabinose is is an orally active antidepressant and a growth inhibitor of C. elegans (IC50 is 7.5 mM). D-Arabinose can penetrate the blood-brain barrier, selectively interfere with the metabolism of D-ribose and D-fructose, and inhibit the growth of nematodes. D-Arabinose can also inhibit the synthesis of cell biofilm and exert antibacterial activity. D-Arabinose activates the ACSS2-PPARgamma/TFEB-CRTC1 axis through the lysosomal AXIN-LKB1-AMPK pathway, inducing CRTC1 transcription, exerts antidepressant-like activity. D-Arabinose is the ring-opened form of the aldopentose D-?Arabinose (HY-N7082)[1][2][3][4][5].
