bax

Bax inhibitor peptide V5 (BIP-V5) is a Bax-mediated apoptosis inhibitor exhibiting anticancer activity.

The compound is a negative control peptide for the Bax inhibitor peptides V5 and P5.

Bax BH3 peptide (55-74), wild type is a 20-amino acid peptide (Bax 1) known for its apoptosis-inducing capability in various cell line models.

Bax inhibitor peptide V5 acetate (Bax inhibitor peptide V5 acetate（579492-81-2 free base)) is a Bax-mediated apoptosis inhibitor, used for cancer treatment.

Bid BH3 (80-99) is a biologically active peptide and a pro-apoptotic member of the 'BH3-only' (BOPS) subset within the BCL-2 protein family, crucial in apoptosis regulation. It interacts with Bcl-2, Bax, and Bak to initiate their activation or inactivation, inducing cell death. Bid translocates from the cytosol to the mitochondrial membrane as part of its mechanism. Pyroglutamyl (pGlu) peptides, which can arise from Glutamine (Q) or Glutamic acid (E) at the N-terminus, have a hydrophobic γ-lactam ring that enhances stability and provides resistance to gastrointestinal proteases. These peptides are recognized variants in peptide analyses, including HPLC purity assessments.

Humanin, a 24-amino acid anti-apoptotic peptide and Bax inhibitor, prevents Bax translocation from the cytosol to mitochondria and obstructs its activation. This mitochondria-associated peptide has neuroprotective properties against Alzheimer's Disease (AD)-related neurotoxicity and enhances insulin sensitivity in animals, linking it to aging processes [1] [2]. An analogue named HNG, with serine at position 14 substituted for glycine, has been developed [2].

BH3 hydrochloride, a peptide that crosses the blood-brain barrier, induces apoptosis either through direct activation of the pro-apoptotic proteins Bax Bak or by inhibiting anti-apoptotic Bcl-2 proteins (Bcl-2, Bcl-XL, Bcl-w, Mcl-1, and A-1) through their BH3 domain [1][2].
