Ringing in new drug candidates
Chemical & Engineering News
Many compound screening collections consist primarily of molecules that do not possess the structural, stereochemical, and functional complexity equivalent to that of natural products. Prof. Paul Hergenrother’s group has reported a new ring distortion method of constructing natural-product-like libraries to address that deficiency. [Full text]

Rescuing CombiChem: Diversity-oriented synthesis aims to pick up where traditional combinatorial chemistry left off
Chemical & Engineering News
What distinguishes DOS from traditional combichem? For one thing, DOS libraries typically consist of tens to hundreds of compounds, versus the tens of thousands to millions of compounds produced in many traditional combinatorial syntheses. Also, most DOS compounds have cyclic architectures and resemble natural products-which are often designed by nature to be biologically active from the start-whereas compounds generated by traditional combichem weren't necessarily that complex.
