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.

    May 21, 2010 · A number of studies have systematically addressed determinants of BH3 peptide binding to pro-survival Bcl-2 family members, and a few have addressed differential interactions with Bcl-x L vs. Mcl-1. 16; 18; 19 Alanine and hydrophile scanning studies have been used to examine the effects of substitutions in several BH3 domains on binding to ...

    For example, draw the major product(s) of the following reaction: For the regiochemistry, we know that according to the Markovnikov’s rule, the Br will be added to the more substituted carbon: Notice that the carbon where the Cl had added became a chiral center, therefore we need to address whether it has an R or S absolute configuration .

    B.Anshuman has given a short answer, but I felt more explanation is needed to understand this situation. This reaction can be done in kineticlly controlled conditions (e.g., using $\ce{LDA/THF}$ as a base at $\pu{-78 ^\circ C}$) or in thermodynamically controlled conditions as in this case. Each case may give totally different major products.

Both glycation and Amadori product formation are completely reversible reactions. But the formation of Advanced Glycation End-products ( AGEs ) by oxidation of Amadori products is irreversible. AGEs in tissues increase the rate of free radical production to 50-times the rate of free-radical production by unglycated proteins.
