Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 50675-18-8, Name is Tetrahydropyran-4-carbaldehyde, molecular formula is C6H10O2. In a Article，once mentioned of 50675-18-8, Reference of 50675-18-8
MK-4256, a tetrahydro-beta-carboline sstr3 antagonist, was discontinued due to a cardiovascular (CV) adverse effect observed in dogs. Additional investigations revealed that the CV liability (QTc prolongation) was caused by the hERG off-target activity of MK-4256 and was not due to sstr3 antagonism. In this Letter, we describe our extensive SAR effort at the C3 position of the tetrahydro-beta-carboline structure. This effort resulted in identification of 5-fluoro-pyridin-2-yl as the optimal substituent on the imidazole ring to balance sstr3 activity and the hERG off-target liability.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 50675-18-8, help many people in the next few years., Reference of 50675-18-8
