pb1

PB1 is a highly-effective intracellular disulfide reducing agent with notable attributes such as excellent cell permeability, the capacity to generate a substantial intracellular concentration gradient, and remarkable stability. It serves as a borane-protected TCEP (tris(2-carboxyethyl)phosphine) analogue. PB1 demonstrates the potential to enhance the survival of retinal ganglion cells following axotomy in vitro at concentrations in the nanomolar and picomolar range. Consequently, PB1 has proven instrumental in the study of neuroprotective properties[1][2][3].

Jegosapogenol A is a type of triterpenoid. Triterpenoids are terpene molecules containing six isoprene units. Barringtogenol C is a very weakly acidic compound (based on its pKa) and practically insoluble (in water). Barringtogenol C exists in tea. It can

PP7 is a potent inhibitor of PB1-PB2 interaction(IC50 of 8.6 μM).

PB118 has the capacity to effectively clear Aβ deposits by augmenting phagocytosis, enhance the tubulin/microtubule network through increased acetyl α-tubulin levels, modulate various inflammation-associated cytokines and chemokines, and notably diminish phospho-tau (p-tau) levels linked to Alzheimer's disease (AD). The IC50 of PB118 for HDAC6 is 5.6 nM.

PB131, a selective and brain-permeable HDAC6 inhibitor, exhibits high binding affinity (IC50: 1.8 nM) and potent anti-inflammatory activity, making it suitable for inflammation research, particularly in neuroinflammation [1].

TPB15 is an orally active inhibitor of Hh (Hedgehog) signalling. TPB15 significantly blocks the MDA-MB-468 cell cycle and induces apoptosis. TPB15 blocks Smo (Smoothened) translocation into cilia and reduces Smo protein and mRNA expression. TPB15 has good anti-tumour effects and low toxicity.

SGC-SMARCA-BRDVIII is a potent and selective inhibitor of SMARCA2, SMARCA4, PB1(2), PB1(3), and PB1(5) with Kds of 35 nM, 36 nM, 3.7 μM, 2.0 μM, and 13 nM, respectively.

NSC 80538 is an inhibitor of MEK Kinase PB1 Domains in multiplex HTS assays.

3-Phenylbutyric acid undergoes metabolism through initial oxidation processes involving both its benzene ring and side chain. It serves as an effective agent for the isolation of Rhodococcus rhodochrous PB1 from compost soil.

RdRP-IN-4 (compound 11q) is an arylbenzohydrazide analogue, an orally active inhibitor of influenza A virus RNA-dependent RNA polymerase (RdRp) that directly binds the PB1 subunit of RdRp. RdRP-IN-4 inhibited H1N1 (A/PR/8/34) Flu A and Flu B strains (B/Lee/1940) in a dose-dependent manner with EC50 values of 53 nM and 20 nM, respectively. RdRP-IN-4 had a significant antiviral effect in infected mice.
