Pteridines CII Synthesis and Characterization of Dimeric Lumazines

Pteridines, 1994
Reduction of 1.3-dimethyllumazine (1) by zinc dust in Ac2O/AcOH leads to the formation of 6-7 connected bis-Iumazinyl derivatives. Depending on the reaction conditions either 7 -(5-acetyl-5,6, 7,8-tetrahydro-1.3-dimethyllumazin- 6-yl)-l, 3 ...

Thyroid hormone regulates distinct paths to maturation in pigment cell lineages [PDF]

, 2019
Thyroid hormone (TH) regulates diverse developmental events and can drive disparate cellular outcomes. In zebrafish, TH has opposite effects on neural crest derived pigment cells of the adult stripe pattern, limiting melanophore population expansion, yet
