Tri-substituted imidazole analogues of SB203580 as inducers for cardiomyogenesis of human embryonic stem cells
摘要:
The p38 alpha mitogen-activated protein kinase (MAPK) inhibitor SB203580 had been reported to enhance the cardiomyogenesis of human embryonic stem cells (hESCs). To investigate if tri-substituted imidazole analogues of SB203580 are equally effective inducers for cardiomyogenesis of hESCs, and if there is a correlation between p38 alpha MAPK inhibition and cardiomyogenesis, we designed and synthesized a series of novel tri-substituted imidazoles with a range of p38 alpha MAPK inhibitory activities. Our studies demonstrated that suitably designed analogues of SB203580 can also be inducers of cardiomyogenesis in hESCs and that cell growth is affected by changes in the imidazole structures.

This invention relates to a method for inducing or enhancing the differentiation of pluripotent stem cells into cardiomyocyte via casein kinase 1 inhibition said method comprising culturing the stem cells in the presence of a medium comprising a casein kinase 1 inhibitor of the formula (I) or (II) or a stereoisomer, tautomer, or a salt thereof wherein R

, O or S; and R

represents hydrogen, optionally substituted alkyl, alkenyl, alkynyl, heterocyclyl, heteroaryl or aryl. The method can be used in the late phase of stem cell differentiation and in the compounds of formula (I) or (II) in combination with other small molecules can lead to especially high differentiation of stem cells into cardiomyocytes. The invention further relates to novel compounds which can be used in the method of the invention and kits for stem cell differentiation.
