摘要
(Chemical Equation Presented) A new tool for developmental biology: A screen of combinatorial chemical libraries identified the 2-amino-4,6- disubstituted pyrimidine 1 as a dose-dependent agonist of Wnt signaling. Tadpoles that developed from embryos treated with 1 had substantial head defects (see right-hand image; left = control). Compound 1 appears to mimic the effects of a Wnt ligand in a Xenopus model and may be a useful tool in the study of physiological processes that involve the Wnt pathway. © 2005 Wiley-VCH Verlag GmbH & Co.
