The library consists of more than 4,000 members belonging 22 scaffolds (average 180 compounds per scaffold).The library includes the following sub-libraries:Cytisine-based sub-libraryMatrine-based sub-libraryPodophyllotoxin-based sub-librarySub-library based on naturally occurring privileged BBS such ashydroxy-prolines, triptamine, nor-tropolone etc.TargetMol “Beyond RO5” filters have been applied for the library population (See Phys-chem parameters for the library members).NO Med-Chem restrictions (widely accepted and proprietary TargetMol substructure filters on reactive functionalities, toxicophoric, instability suspicions etc.).More than 90% purity for each library member confirmed by LC-MS or NMR analysis.
