The BH3 interacting-domain death agonist, or BID, gene is a pro-apoptotic member of the Bcl-2 protein family. Bcl-2 family members share one or more of the four characteristic domains of homology entitled the Bcl-2 homology (BH) domains (named BH1, BH2, BH3 and BH4), and can form hetero- or homodimers. Bcl-2 proteins act as anti- or pro-apoptotic regulators that are involved in a wide variety. The novel small molecular BH3 mimetics SM3 and its regulation of cell apoptosis and autophagy Bcl-2 family proteins play an important role in regulation of the cell survival and death.

  1. BH3-mimetics are small molecule inhibitors that neutralize the function of anti-apoptotic BCL-2 family members. BH3-mimetics have recently gained a lot of popularity in oncology because of their success in cancer treatment. However, BH3-mimetics might have a broader clinical application. Here, we established an ex vivo flow cytometric assay allowing the comparison of the impact of BH3-mimetics (ABT-199, ABT-263, WEHI-539, and S63845) on leukocyte populations of both, healthy human subjects.
  2. This prompted a model in which the BH3 domain-only molecules could be subdivided into two groups: molecules typified by BID, which can bind and appear to activate proapoptotic BAX, BAK versus molecules such as BIM, BAD, and NOXA, which preferentially bind to and thus are presumed to function by inhibiting antiapoptotic BCL-2, BCL-X L Huang and Strasser 2000, Kelekar and Thompson 1998. The proapoptotic activity of BH3 domain-only molecules is kept in check by either transcriptional.
  3. Several examples of small molecules which modulate Mcl‐1 have been reported, with a variety of reviews addressing patented compounds, 15 compounds in clinical trials 8 and pan‐Bcl‐2 inhibitors. 16 Most recently, Belmar and Fesik presented an excellent review of Mcl‐1 binders which are known to be BH3 mimetics. 17 The scope of this review will target a comprehensive overview of known.
  4. Synthetic reagents that mimic BH3 sensitizers have high therapeutic potential. For example, the small-molecule BH3 mimetic ABT-263, or Navitoclax, is being tested in humans following extremely promising results in mice. However, ABT-263 only binds Bcl-2, Bcl-x L, and Bcl-w, and cancers that also express Bfl-1 or Mcl-1 show resistance to the drug
  5. BH3‐only proteins are able to displace Bax/Bak molecules from this complex, leading to their activation and eventually apoptosis (Fig. 3B). This is consistent with the observation that proteins such as Bim and Puma are potent killers and show promiscuous high‐affinity binding of anti‐apoptotic Bcl‐2 family proteins, whereas less potent killers bind only a selected subset of pro.

The NH3 molecule can also participate in a similar catalytic process but induces a smaller reduction of the energy barrier. The kinetics of these processes was analyzed by both transition-state and RRKM theory. The catalytic effect of BH3 has also been probed by an analysis of the electronic densities of the transition structures using the atom-in-molecule (AIM) and electron localization function (ELF) approaches This prompted a model in which the BH3 domain-only molecules could be subdivided into two groups: molecules typified by BID, which can bind and appear to activate proapoptotic BAX, BAK versus molecules such as BIM, BAD, and NOXA, which preferentially bind to and thus are presumed to function by inhibiting antiapoptotic BCL-2, BCL-X To screen for small molecules that specifically target Bcl-XL, a library containing approximately 300,000 small molecules from the NCI was used to dock the structural pocket of the BH3 domain (aa90-98; accession number: 1LXL and 1MAZ) using the UCSF DOCK 6.1 program suite as described .

Abstract. BH3-mimetics are small molecule inhibitors that neutralize the function of anti-apoptotic BCL-2 family members. BH3-mimetics have recently gained a lot of popularity in oncology because. These BH3 peptides (which we term derepressor BH3s) require the presence of another molecule that can directly activate Bax, e.g., Bid or Bim. Furthermore, we found that some of the BH3 peptides differentially counteract Bcl-x L and Mcl-1, arguing that the derepression function of the peptides is determined essentially by their interactions with specific antiapoptotic family members ABT-737 is a small molecule mimetic of the proapoptotic BH3 domain that can be used as a competitive inhibitor of antiapoptotic BCL-2 function. Treatment with ABT-737 can displace prodeath BH3-containing molecules from BCL-2, allowing for the progression of death signaling. We hypothesized that if BCL-2 is protecting from cell death by binding proapoptotic BH3-containing proteins generated by EGFR inhibition, then ABT-737 should reverse the protection afforded by BCL-2.

In this context, a variety of terphenyl-based compounds that mimic the alpha-helical region of the pro-apoptotic Bak BH3 domain has already been identified. These compounds were used as lead compounds for an in silico screening in our database which contains more than four million drug-like molecules. During this screening, the compounds from the virtual database were compared with the lead compounds by 2D and 3D similarities. After additional property filtering and docking experiments, five. Wang et al. (1996) identified a gene they termed BID (BH3 Interacting domain Death agonist) that encodes a novel death agonist that heterodimerizes with either agonists (BAX) or antagonists (BCL2). BID possesses only the BH3 domain, lacks a C-terminal signal-anchor segment, and is found in both cytosolic and membrane locations.

For example, in BF 3, the It has been shown in many solid tumors that the overexpression of the pro-survival Bcl-2 family members Bcl-2/Bcl-xL and Mcl-1 confers resistance to a variety of chemotherapeutic agents. We designed the BH3 α-helix mimetic JY-1-106 to engage the hydrophobic BH3-binding grooves on the surfaces of both Bcl-xL and Mcl-1. JY-1-106-protein complexes were studied using molecular dynamics (MD. InterPro provides functional analysis of proteins by classifying them into families and predicting domains and important sites. We combine protein signatures from a number of member databases into a single searchable resource, capitalising on their individual strengths to produce a powerful integrated database and diagnostic tool

Molecule Bh3 Only Mimetic, supplied by Abbott Laboratories, used in various techniques. Bioz Stars score: 85/100, based on 1 PubMed citations. ZERO BIAS - scores, article reviews, protocol conditions and mor Functions as a proapoptotic molecule through the caspase-dependent mitochondrial pathway of cell death Purpose: Predictive biomarkers are required to identify patients who may benefit from the use of BH3 mimetics such as ABT-263. This study investigated the efficacy of ABT-263 against a panel of patient-derived pediatric acute lymphoblastic leukemia (ALL) xenografts and utilized cell and molecular approaches to identify biomarkers that predict in vivo ABT-263 sensitivity
