DOI: 10.1039/C5CC04813C, CommunicationAlexander W. Beebe, Emma F. Dohmeier, Gustavo Moura-Letts
Diastereopure substituted diaziridines from simple ketones, aldehydes and amines are here reported. These important chemical scaffolds are obtained in the presence of a weak inorganic base and hydroxylamine O-sulfonic acid (HOSA). This method provides a wide variety of substituted diaziridines with high yields and diastereoselectivities.

A fluorescent G-quadruplex probe for the assay of base excision repair enzyme activity

29 July, 2015 - 11:17

Chem. Commun., 2015, Advance Article
DOI: 10.1039/C5CC05010C, CommunicationChang Yeol Lee, Ki Soo Park, Hyun Gyu Park
A G-quadruplex probe incorporating 2-AP is utilized to develop a novel strategy to accurately determine UDG activity. The excision reaction promoted by UDG is designed to trigger the formation of G-quadruplex structure with significant fluorescence enhancement of 2-AP within the probe. By employing this strategy, UDG activity can be reliably determined with high sensitivity and specificity.
