HDB-1 is a selective inhibitor of the P2Y14 receptor ( P2Y14R ) with an IC50 of 26 pM. HDB-1 shows no significant inhibition on P2Y1R, P2Y2R, P2Y4R, P2Y6R, and P2Y12R. HDB-1 blocks the activation of hepatic stellate cells (HSC) by inhibiting the PKA/Raf1/MEK/ERK signaling pathway mediated by P2Y14R, thereby alleviating the core pathological process of liver fibrosis. HDB-1 can be used for the study of liver fibrosis [1].
