D-Arabinopyranos-13C5 is 13C labeled D-Arabinopyranos (HY-N7082). D-Arabinopyranose is a rare aldehyde pentose, and its ring-opened form is 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].
