We report herein comprehensive investigations of alkylation/sulfur exchange reactions of sulfur-containing substrates including nucleosides such as s2U, m5s2U, s4U, s2A and s2T-incorporated DNA enable by comprehensive screenings of the reagents (2a–2h). It has been proven that iodoacetamide (2a) displays the most promising feasibility toward sulfur-containing substrates including s2T, s2U, m5s2U, s4U and s2A. In sharp contrast, the alkylation process with S-benzyl methanethiosulfonate (BMTS, 2h) displays the best application potential only for s4U. Based on these results, the fluorescent labeling of s2T-incorporated DNA and m5s2U-modified RNA has been achieved.

Labile zinc plays various roles in cells at low concentrations which most fluorescent probes are not able to detect. Here we report a cephem-based probe which coordinates to zinc and zinc-bound water cleaves the scaffold and releases the fluorophore. In addition, the zinc is recycled and reacts with multiple probes, amplifying the signal. This signal amplification system is useful for the detection of intracellular zinc at low concentrations and has potential for further development of probes with a similar molecular design.

In order to improve the antitumor potency of the natural product evodiamine, novel boron-containing evodiamine derivatives were designed by incorporating boronic acid and boronate as trigger units. Boronate derivative 13a could be triggered by reactive oxygen species (ROS) in the HCT116 colon cancer cell line and showed excellent antitumor activity in vitro and in vivo. It induced apoptosis in HCT116 cancer cells in a dose-dependent manner and cell growth arrest at the G2 phase.
