Abstract:
An innovative and efficient reagent- and scaffold-based diversity oriented synthesis (DOS) of a fragment set was developed for fragment-based drug discovery (FBDD) programs. Twelve diverse, functionalized and bicyclic scaffolds were rapidly accessed by adopting a convenient synthetic toolkit around three privileged azine cores in order to effectively modulate biomolecules. These structures are characterized by both key motifs for interacting with diverse biological targets via hydrogen bonds and useful points of growth for subsequent fragment optimization.

Lagging Strand Synthesis
There are several major differences between synthesis of the leading strand and synthesis of the lagging strand. 1) Leading strand synthesis happens in the direction of replication fork opening, whereas lagging strand synthesis happens in the...
