pih

PIH is a ciliogenesis inhibitor by microtubule destabilization that acts by antagonizing Hh signaling by repressing cilia biogenesis and disassembly of alpha-tubulin in its stabilized form.

pyridoxal isonicotinoyl hydrazone (PIH) 是亲脂的三价铁螯合剂，具有高铁螯合特性。

6-Epiharpagide is a natural product from Scrophularia ningpoensis Hemsl.

6-Epiharpagoside 是一种天然产物，可用于生命科学领域的相关研究。其产品编号为 TN3167，CAS号为 1151862-67-7。

NDPIH，源自猴头菇（Hericium erinaceus），具有显著的神经营养活性，可在无血清的条件下促进培养的海马神经元中大量轴突生长和神经突触分支。尽管药理学上抑制肌动蛋白受体激酶B（TrkB）只能部分阻止NDPIH诱导的活性，NDPIH还是能独立于TrkB激活ERK1 2信号通路。

p-MPPI hydrochloride 是一种选择性的，具有高亲和力的5-HT1A 受体拮抗剂，能穿过血脑屏障，具有抗抑郁和抗焦虑样作用。

FIPI is an effective and selective phospholipase D inhibitor that reduces mercury-induced lipid signaling and thus protects aortic endothelial cells from cytotoxicity.

Potent positive allosteric modulator of α4β2 nAChRs (EC50 values are 20 and 18 nM for rat and human, respectively). Selective for hα4β2 over hα3β2, hα3β4 and hα7. Inhibits (α4)2(β2)3, muscle-type and Torpedo nAChRs (IC50 values are 0.5, 0.7 and 0.2 μM, respectively), but not (α4)3(β2)2 receptors. Exhibits ability to photoincorporate into aliphatic and nucleophilic amino acid side chains.
