Synthesis and Crystal Structure of 9,12-Bis-(4-acetylphenyl)-1,2-dicarbadodecaborane(12):  Self-Assembly Involving Intermolecular Carboranyl C−H Hydrogen Bonding

Stabilization of α-helix structure by polar side-chain interactions: Complex salt bridges, cation–π interactions, and C–H … O H-bonds

“…O H-bonds. 105 However, when Sutor proposed the existence of this general type of H-bonding bility and specificity of transmembrane helices, 130 the mechanism of serine protease catalysis, 68, 131 crystal engineering, [133][134] and superamolecular assemblies. 135 There is still a lack of experimental data concerning the energetics of these nonconventional noncovalent interactions in protein or polypeptides.…”

Exploring the C–H…O Interactions in Glycoproteins

“…C-H…O interactions are now understood to be present in many biological systems, including proteins [18][19][20][21][22], nucleic acids [23][24][25][26][27][28][29], and carbohydrates [30]. C-H…O interactions have also been implicated in the interaction of nucleic acids with proteins [31,32], drug binding [33][34][35], the stability and specificity of trans-membrane helices [36], the mechanism of serine protease catalysis [37], crystal engineering [38][39][40], and super-molecular assemblies [16].…”

Contribution of CH· · ·X Hydrogen Bonds to Biomolecular Structure

“…The decade of the 1990s saw what could arguably be termed an explosion of studies of the CHÁ Á ÁX interaction that broadened the sorts of systems that engage in this phenomenon, while better defining it [31,32]. Alkynes and alkenes were found to participate in such bonds [33][34][35][36], as did aryl groups [37][38][39][40][41][42], and even CH groups present in smaller rings [43,44], carboranes [45] and even cubyl arrangements [46]. Organometallic systems were also found to contain such bonds on a regular basis [47][48][49].…”
