pih

pyridoxal isonicotinoyl hydrazone (PIH) is a cell-permeable and relatively non-toxic iron (Fe3+) chelator that shows high iron chelation efficacy both in vitro and in vivo.

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.

Epihygromycin is a glycoside antibiotic with relatively weak activity against Gram-positive bacteria.

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

6-Epiharpagoside is a natural product for research related to life sciences. The catalog number is TN3167 and the CAS number is 1151862-67-7.

NDPIH, derived from Hericium erinaceus (monkey head mushroom), exhibits significant neurotrophic activity. It enhances extensive axonal growth and synaptic branching in cultured hippocampal neurons under serum-free conditions. Although pharmacological inhibition of actin receptor kinase B (TrkB) partially blocks the activity induced by NDPIH, the compound can independently activate the ERK1/2 signaling pathway, bypassing TrkB.

p-MPPI hydrochloride is a selective 5-HT1A receptor antagonist with antidepressant and anxiolytic-like effects.

UCN-02 (7-epi-Hydroxystaurosporine) is a selective and highly potent protein kinase C (PKC) inhibitor produced by Streptomyces N-126 strain, inhibiting PKA. UCN-02 has antitumor activity.

VU0360172 is a positive allosteric modulator of mGlu5 receptors (EC50 = 16 nM; Ki = 195 nM).

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.

CMPI hydrochloride, a potent and selective nAChR agonist, functions as a positive allosteric modulator (PAM) specifically targeting the α4:α4 subunit interface of the nAChR. It enhances the response of the (α4)3(β2)2 nAChR to acetylcholine (ACh) (10 μM) with an EC 50 of 0.26 μM. With its potential for researching nicotine dependence and various neuropsychiatric conditions linked to reduced brain cholinergic activity, CMPI hydrochloride stands as a significant compound in neurological research.

8-epi-Helenalin, a sesquiterpene lactone with anti-tumor properties, is derived from Inula britannica L. var. chinensis (Rupr.) Reg. It demonstrates cytotoxic activity against a range of cancer cell lines, with ED50 values of 12.2 μM for HL-60, 53.8 μM for A549, 9.1 μM for MCF7, 8.7 μM for HCT-15, 18.7 μM for SK-OV-3, and 8.3 μM for Malme-3M, indicating its potential for anti-tumor research [1].

2-Methyl-α-pyrrolidinoisohexanophenone (hydrochloride) (2-Methyl-α-PiHP (hydrochloride)) is a type of ksyton compound.

VH-N412 is a carrier-modified neurotrophin (NT) known for its excellent ability to penetrate the blood-brain barrier. This compound actively binds to both low-density lipoprotein receptor (LDLR) and neurotropin receptor 1 (NTSR-1), acting as an inducer of pharmacologically induced hypothermia (PIH). Additionally, VH-N412 exhibits anticonvulsant and neuroprotective properties, making it a valuable agent for research in neurological disorders such as epilepsy.
