Scaffold hopping is a powerful approach for scientists in their quest for a novel molecule from among the complex maze of patents.

Conventional combinatrorial library generation technologies generate library through substitution of groups on a given molecule template. The template in such a library remians unchanged, significantly limitating the diversity in the library generated.

LeadGrow+ removes this limitation and allows even the template to be substituted, thus enabling systematic exploration of chemical space for different scaffolds. This allows exploration of various scaffolds in library enumeration. Further LeadGrow+ provides scaffold hopping as a strategy to design new molecules and ensuring significant chemical diversity in the generated library.

LeadGrow+ thus creates diverse libraries that systematically explore available chemical space and helps researchers in the quest of novelty and uniqueness in new molecule design.

Advantages of LeadGrow+
Explore a wider chemical universe
LeadGrow+ enables an unprecedented ability to explore a larger chemical space by generating combinatorial libraries based on multiple templates. The ability to explore not only multiple templates but also individual groups on each fragment provides an unprecedented coverage of the working chemical space.
Allows substitutions on individual groups within a fragment
LeadGrow+ enables a rigorous scanning of the chemical space by allowing library generation with substitutions on individual groups on each fragment of a template.
Library creation based on screening criteria
The multiple screening functions in LeadGrow+ provide an ability to generate a focused combinatorial library satisfying the particular screening critera.

"This new QSAR methodology gives QSARpro, a decisive edge over conventional QSAR. The ability to combine kNN with MFA is a unique approach which I came across only in QSARpro from VLife. It is now a method of choice in my research."
