Express Lead Library

Please contact us at

Development of the lead-oriented synthesis as a solution to provide large arrays of quality lead generating screening libraries with strictly controlled properties is dependent on access to the novel molecular scaffolds. Such starting points must be small enough to enable significant diversity of the derivatives and, at the same time, must possess molecular properties allowing for wide variations of the substituents within lead-like chemical space.

Express Lead Library is a new product of Enamine that offers unprecedented fast access to the novel lead-like libraries at affordable prices. Such libraries can be synthesized and delivered in only 2-3 weeks. We have carefully selected 3 758 most interesting core building blocks from our stock collection to compose a basis of Express Lead Library. They fall in the following categories:

Bridged 137
Spiro 306
Medium-sized rings 239
Fused saturated rings 152
Fused aromatic & saturated rings 507
 
Saturated rings 175
Aromatic-saturated rings 1 058
Isolated rings 470
Aromatic rings 247
Monocyclic 467

The core building blocks can be grouped in clusters sharing common or bioisosteric cores. Each such cluster can yield diverse multidimensional screening libraries in just one synthesis step! Express lead library or any part of it can be also provided as SDF so that one can run virtual screening to identify the most promising synthesis candidates. Cherry picking will not influence price. Examples of the core building block clusters are pictured below.
