pb-1

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.

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].

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.

PFI-3 is a selective chemical inhibitor for SMARCA (2/4) (Kd = 89 nM)and PBI (5) bromodomains which may result in the delay and prevention of breast cancer.

NPB-1575 is a potent, orally active anti-inflammatory agent capable of crossing the blood-brain barrier. It mitigates neuroinflammation and resists ferroptosis by activating IRS2/Nrf2/NF-κB. NPB-1575 protects against cerebral ischemic injury and improves neurological function outcomes, making it suitable for research in focal ischemic stroke.

OPB-111077 is an inhibitor of one or more signal transducers and activators of transcription (STAT) proteins.

OPB-171775 is a molecular glue that forms a ternary complex with phosphodiesterase 3A (PDE3A) and schlafen family member 12 (SLFN12). This compound induces cell death mediated by SLFN12 RNase, activates the SLFN12 RNase-associated GCN2 signaling pathway, and demonstrates antitumor activity.

Ribavirin (Tribavirin) is a synthetic nucleoside analog of ribofuranose with activity against hepatitis C virus and other RNA viruses.

GNF-2 is a highly selective non-ATP competitive inhibitor of Bcr-Abl.

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

PB17-026-01 is an effective allosteric inhibitor of SHP2, exhibiting its highest inhibitory activity with an IC50 of 38.9 nM. PB17-026-01 is applicable to cancer research.

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.

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].

PBT-1033 (PBT-2) is a potential neuroprotective agent for the treatment of Alzheimer's disease and Huntington's disease.

PB-119 is a PEGylated exenatide that lowers blood glucose levels by enhancing β cell function and reducing insulin resistance. It is applicable in studies related to type 2 diabetes.

Bentracimab (PB 2452) is a monoclonal antibody that neutralizes Ticagrelor and its primary active metabolite by binding with high affinity, rapidly reversing Ticagrelor's antiplatelet effects [1].

Pneumolysin-IN-1 (compound PB-3), characterized as a targeted small molecule inhibitor of Pneumolysin (PLY) with an IC50 value of 3.1 µM, acts as a pore-blocking agent and an anti-virulence factor. This compound is useful for researching infections caused by Streptococcus pneumoniae [1].

PB(OH)3 is an anti-HIV-1 agent utilized in antiviral research.
