ASH1L histone methyltransferase regulates the handoff between damage recognition factors in global-genome nucleotide excision repair

Nature Communications, 2017
UV-induced mutagenic cyclobutane pyrimidine dimers on nucleosomal DNA are sensed by the damage recognition factors DDB2 and XPC via an unknown mechanism. Here, the authors show that the histone methyltransferase ASH1L regulates the DDB2 to XPC handoff by

1-(3-Mesityl-3-methylcyclobutyl)-2-phenoxyethanone

Acta Crystallographica Section E, 2010
In the title compound, C22H26O2, the cyclobutane ring is puckered, with a dihedral angle of 24.97 (9)° between the two C3 planes. In the crystal, intermolecular non-classical C—H...O interactions between the methylcyclobutyl ...

The autoignition of cyclopentane and cyclohexane in a shock tube

, 2007
Ignition delay times of cyclohexane-oxygen-argon and cyclopentane-oxygen-argon mixtures have been measured in a shock tube, the onset of ignition being detected by OH radical emission.

DNA damage [PDF]

, 2008
Even under the best of circumstances, DNA is constantly subjected to chemical modifications. Several types of DNA damage such as SSB (single strand break), DSB (double strand break), CPDs (cyclobutane pyrimidine dimers), 6-4PPs (6-4 photoproducts) and ...

A modular approach to prepare enantioenriched cyclobutanes: synthesis of (+)-rumphellaone A [PDF]

, 2019
A modular synthesis of enantioenriched polyfunctionalized cyclobutanes was developed that features an 8-aminoquinolinamide directed C–H arylation reaction. The C–H arylation products were derivatized through subsequent decarboxylative coupling processes.

Mechanochemistry of cyclobutanes

Science China Chemistry
AbstractThe field of polymer mechanochemistry has been revolutionized by implementing force-responsive functional groups—mechanophores. The rational design of mechanophores enables the controlled use of force to achieve constructive molecular reactivity and material responses.

Some remarks on the use of experimental bond lengths in the maximum overlap method [PDF]

, 1970
The hybridization in norbornane, ethane, acetylene, cyclo- propane, cyclobutane and cyclopentane has been reexamined by the maximum overlap calculations based on experimental bond lengths.
