rac-(6S)-6-Hy­droxy-6-{2-[2-(propan-2-yl­idene)hydrazinyl­idene]prop­yl}indolo[2,1-b]quinazolin-12(6H)-one

The chiral title compound, C(21)H(20)N(4)O(2), crystallizes as a racemic mixture. In the crystal, mol-ecules form centrosymmetric π-overlapping dimers [inter-planar distance = 3.338 (6) Å], which are further connected along the a axis forming centrosymmetric dimers via O-H⋯N hydrogen bonds. C-H⋯O inter-actions are also observed. The indolo[2,1-b]quinazoline group is somewhat bent, with a small ...

rac-2-Amino-1,2-diphenyl­ethanol

In the title compound, C(14)H(15)NO, the torsion angle about the two Csp(3) atoms adopts a partially eclipsed conformation [-61.5 (1)°]. The dihedral angle between the two rings is 48.1 (1)°. In the crystal, the mol-ecules are connected by O-H⋯N and N-H⋯O hydrogen bonds into zigzag chains running along [010]. One of the amino H atoms is not involved in hydrogen bonding.

Stereogenic boron in 2-amino-1,1-diphenylethanol-based boronate–imine and amine complexes

Racemic boronate-imine and boronate-amine complexes 8 and 10, both featuring a stereogenic boron atom were synthesized from 2-amino-1,1-diphenylethanol (5) and characterized by crystal structure analyses. Proof of enantiomerism at the boron center for the novel boronate-amine complex 10 was established by separation of the enantiomers. Racemization barriers were found to be in the same range fo...

RAC 2 ( ras - related C 3 botulinum toxin substrate 2 ( rho family , small GTP binding protein Rac 2 ) ) Teresa

The Rac2 gene sequence contains 7 exons (Courjal et al., 1997) and is expressed specifically in hematopoietic cells. Human Rac2 gene locus is silenced in non-hematopoietic cells by a mechanism that involves DNA methylation (Ladd et al., 2004). Cells that lack Rac2 expression exhibit increased cytosine methylation in the sequences flanking the gene, whereas cells that express Rac2 exhibit increa...
