We designed a series of 2-methylpyrimidine derivatives as new BCR-ABL inhibitors using scaffold-hopping strategy.These synthetic compounds exhibited significant inhibition against a broad spectrum of Bcr-Abl mutants i...
The revolutionary induced pluripotent stem cell (iPSC) technology provides a new path for cell replacement therapies and drug screening. Patient-specific iPSCs and subsequent differentiated cells manifesting disease...
Phytochemical investigation on the leaves ofNeolamarckia cadamba led to the isolation of four new indole al- kaloids, spirocadambine (1), dehydraisodihydrocadambine (2), nitrocadambines A and B (3 and 4). The st...
Environmental stress-mediated adaptation plays essential roles in the evolution of life. Cellular adaptation mechanisms usually involve the regulation of chromatin structure, transcription, mRNA stability and translat...

Sixβ-carboline alkaloids including three new ones,trifilines A-C(1-3)were isolated from Trigonostemon filipes,along with a newβ-carboline alkaloid,trigonoine C(7)isolated from Trigonostemon lii.Their structures were...
Somatic cells can be reprogrammed into induced pluripotent stem cells (iPSCs) by defined factors. The low efficiency of reprogramming and genomic integration of oncogenes and viral vectors limited the potential appl...
