Glycolipids are important structural components of biological membranes and perform crucial functions in living systems, including signaling transduction and interaction with extracellular environment. However, the mechanistic exploration of glycolipids in vivo is challenging because they are not genetically encoded. Herein, we designed and synthes...

Natural products have been extensively used to treat diseases throughout human history. These are mainly because natural products normally target biological macromolecules selectively. Target identification could help us to develop new therapeutic agents and discover new biological pathways underlying human diseases. Herein, we highlight some recen...

The use of chemoprotective agents to minimize the side effects of the chemotherapy, primarily via activation of the Nrf2 pathway, is an emerging research field, which has attracted broad attention from both academia and pharmaceutical industry. Through high-throughput chemical screens we have disclosed that pterisolic acid B (J19), a naturally occu...

Genetically programmed cell death is a universal and fundamental cellular process. Apoptosis and necrosis are two common features of programmed cell death that play vital roles in maintainance of homeostasis in metazoans. Dysfunction in the regulatory machinery of these processes can lead to carcinogenesis or autoimmune diseases. On the other hand,...

Bioorthogonal ligations play a crucial role in labeling diverse types of biomolecules in living systems. Herein, we describe a novel class of ortho-quinolinone quinone methide (oQQM) precursors that show faster kinetic rate in the "click cycload-dition" with thio-vinyl ether (TV) than the first generation TQ-ligation in both chemical and biological...

Aberrant activation of NF-κB is associated with the development of cancer and autoimmune and inflammatory diseases. IKKs are well recognized as key regulators in the NF-κB pathway and therefore represent attractive targets for intervention with small molecule inhibitors. Herein, we report that a complex natural product ainsliadimer A is a potent in...

Herein, we report an efficient approach for exploring the novel anticancer mechanism of (−)-ainsliatrimer A, a structurally complex and unique trimeric sesquiterpenoid, through a combined strategy of diverted total synthesis (DTS) and bioorthogonal ligation (TQ ligation), which allowed us to visualize the subcellular localization of this natural pr...

Bioorthogonal ligations have found widespread use in biomedical research for site selective labeling of biomolecules in living systems. Discovering new reactions to expand the toolbox of bioorthogonal chemistry remains an important, yet challenging task as most reactions do not meet the stringent requirements of bioorthogonal reaction. As highly us...

There is an increasing interest in the use of bioorthogonal ligation to advance biomedical research through selective labeling of biomolecules in living systems. Accordingly, discovering new reactions to expand the toolbox of bioorthogonal chemistry is of particular interest to chemical biologists. Herein we report a new bioorthogonal ligation enab...

Ainsliatrimers A and B are two recently isolated complex sesquiterpenoid natural products that display the unprecedented chemical motifs and remarkable anti-cancer activities. The exact structures as well as the mechanism of anti-cancer action for ainsliatrimers A and B remain to be elucidated. Here we report the first concise and biomimetic synthe...

Microbial transformation of the steroidal sapogenin diosgenin (1) by resting cells of the filamentous fungus, Cunninghamella echinulata CGMCC 3.2716 was studied. Four metabolites were isolated and unambiguously characterized as (25R)-spirost-5-ene-3β,7β-diol-11-one (2), (25R)-spirost-5-ene-3β,7β-diol (3), (25R)-spirost-5-ene-3β,7β,11α-triol (4), an...
