Scaffold hopping via ANCHOR.QUERY:beta-lactams as potent p53-MDM2 antagonists
Using the pharmacophore-based virtual screening platform ANCHOR.QUERY, we morphed our recently described Ugi-4CR scaffold towards a beta-lactam scaffold with potent p53-MDM2 antagonizing activities. 2D-HSQC and FP measurements confirm potent MDM2 binding. Molecular modeling studies were used to understand the observed SAR in the beta-lactam series
Versatile multicomponent reaction macrocycle synthesis using α-isocyano-Ï-carboxylic acids
The
direct macrocycle synthesis of α-isocyano-Ï-carboxylic
acids via an Ugi multicomponent reaction is introduced. This multicomponent
reaction (MCR) protocol differs by being especially short, convergent,
and versatile, giving access to 12â22 membered rings
Instant Macrocyclizations via Multicomponent Reactions
Macrocycles fascinate chemists due to both their structure
and
their applications. However, we still lack efficient and sustainable
synthetic methods, giving us straightforward access to them. Herein,
a rapid macrocyclization utilizing a two-step, one-pot approach based
on orthogonal multicomponent reaction (MCR) tactics is introduced.
This synthetic protocol, which is based on Ugi and GroebkeâBlackburnâBienaymeÌ
reactions with isocyanides tethered to alkyl tosylates, yields medium
sized macrocycles that are otherwise difficult to achieve. Single
crystal structures reveal conformational reorganization via intramolecular
hydrogen bonding, and modeling studies profile the synthesized libraries
