Enantioconvergent Deacylative Functionalization toward α‐Quaternary Nitriles

Angewandte Chemie, EarlyView.
An enantioconvergent quaternary‐to‐quaternary synthesis of α‐chiral nitriles has been enabled. By replacing the acyl group with a variety of allyl, propargyl, and benzyl motifs, the functional group swap can convert easily available β‐ketonitriles to assorted quaternary stereocenters en route to bioactive molecules of broad interests.

Tailored Fluorescent Metal–Organic Frameworks Hybrid Membrane Sensor Arrays: Simultaneous and Selective Quantification of Multiple Antibiotics

Advanced Science, EarlyView.
A filterable paper‐based fluorescent metal–organic frameworks (MOFs) sensor array is developed for one‐to‐one recognition and simultaneous quantification of multiple antibiotics. Three representative MOFs are strategically designed to exhibit exceptional affinity and specificity for the target antibiotic.

Fast and Autonomous Mannosylated Nanomotors for Dynamic Cancer Cell Targeting

Angewandte Chemie, EarlyView.
An enzyme‐loaded nanomotor decorated with mannose polymers shows a synergistic effect with respect to cell targeting. The mannose units interact with mannose receptors (MRs) on the cell surface, whereas the presence of the glycopolymer on the motor surface also leads to a more effective motile behavior in cell medium. Abstract An attractive strategy in

Mutations In RAD27 Define A Potential Link Between G₁ Cyclins And DNA Replication [PDF]

, 1995
The yeast Saccharomyces cerevisiae has three G1 cyclin (CLN) genes with overlapping functions. To analyze the functions of the various CLN genes, we examined mutations that result in lethality in conjunction with loss of cln1 and cln2.
