WebFluorescence polarization binding studies and nuclear magnetic resonance structural analyses have revealed that racemic gossypol binds to the BH3 binding pocket of Bcl-xl with a K i of ~0.3 μM and to the BH3 binding pocket of Bcl-2 with a K i of ~10 μM. 29 AT-101 inhibits Bcl-2 and disrupts heterodimerization of Bcl-2, myeloid cell leukemia 1 ... The standard enthalpy of dimerization of BH 3 is estimated to be −170 kJ mol −1. [6] The boron atom in BH 3 has 6 valence electrons. Consequently, it is a strong Lewis acid and reacts with any Lewis base ('L' in equation below) to form an adduct: BH 3 + L → L—BH 3 in which the base donates its lone pair, forming a … See more Trihydridoboron, also known as borane or borine, is an unstable and highly reactive molecule with the chemical formula BH 3. The preparation of borane carbonyl, BH3(CO), played an important role in exploring the … See more Molecular BH3 is believed to be a reaction intermediate in the pyrolysis of diborane to produce higher boranes: B2H6 ⇌ 2BH3 BH3 +B2H6 → B3H7 +H2 (rate determining step) BH3 + B3H7 ⇌ B4H10 B2H6 + B3H7 → BH3 + B4H10 ⇌ B5H11 + H2 See more BH3 is a trigonal planar molecule with D3h symmetry. The experimentally determined B–H bond length is 119 pm. In the absence of other chemical species, it reacts with itself to form diborane. Thus, it is an intermediate in the preparation of diborane according … See more • Butterfly cluster compound See more
