A new family of diverse skin peptides from the microhylid frog genus phrynomantis [PDF]

, 2020
A wide range of frogs produce skin poisons composed of bioactive peptides for defence against pathogens, parasites and predators. While several frog families have been thoroughly screened for skin-secreted peptides, others, like the Microhylidae, have ...

Identification of tumor-related genes via RNA sequencing of tumor tissues in Xenopus tropicalis

Scientific Reports, 2023
Cancer treatment is still challenging because the disease is often caused by multiple mutations. Although genomic studies have identified many oncogenes and tumor suppressor genes, gene sets involved in tumorigenesis remain poorly understood.

Convergent Total Synthesis of 16β‐Hydroxylpseudobufarenogin

Angewandte Chemie, EarlyView.
We present a novel convergent strategy that integrates Pd/Ag‐promoted Suzuki–Miyaura coupling with Ir‐catalyzed radical‐relay cyclization, enabling the first total synthesis of 16β‐hydroxylpseudobufarenogin. This approach is broadly applicable to the total synthesis of various oxygenated bufadienolides by simply modifying the fragment structures ...

Development of swimming speed-based biomarker reveals interactive toxicity of TCEP and TCPP in amphibian larvae

Ecotoxicology and Environmental Safety
Tris(2-chloroethyl) phosphate (TCEP) and tris(2-chloro-1-methylethyl) phosphate (TCPP) are increasingly co-detected in various aquatic environments, yet their combined toxicity remains poorly understood.
