Enamine and H. Lundbeck A/S (Lundbeck) announced the expansion of their research collaboration. Enamine will support Lundbeck’s in-house discovery chemistry competencies with three principal assets enabling Lundbeck to optimally identify and develop hit series in its multiple research programs. A large diverse library of 100 000 new screening compounds was done for hit finding activities on numerous therapeutic targets. Enamine’s make-on-demand REAL compounds are for efficient access to billions of novel chemical compounds. Enamine FTE increased dedicated team of chemists to effectively support Lundbeck on all hit related follow-up activities backed by immediate access to over 170 000 building blocks in Enamine’s inventory.
Scientists at the UCSF, together with colleagues at the UNC, created the largest “docking-friendly” database of molecules, based on the Readily Accessible (REAL) compounds from Enamine. Practical validation of the new database was recently published in Nature magazine, demonstrating that it is capable of identifying extremely powerful and synthetically available new hits.
EU-funded project PELICO, under Enamine’s coordination, reports promising results in synthesis of peptides, their pharmacokinetic and toxicity studies, and coupling with photo-controlled building blocks to yield new photo-controlled peptidomimetics.

Wnt/sFRP-1 Interaction Inhibitors Library

1 346 compounds
This selection of small molecules takes into consideration Wnt/sFRP-1 (Secreted Frizzled Related Proteins) interaction. sFRP-1 family of proteins include endogenous molecules that bind both Wnt ligands and Fz receptors.
Fig. 1.Epigenetic inactivation of negative regulators of WNT signaling. (a) In cancer cells, epigenetic inactivation of SFRP and DKK enables β-catenin to translocate to the nucleus, which leads to activation of WNT signaling. (b) In normal cells, SFRP and DKK are associated with key WNT signaling molecules such as WNT ligands and LRP5/6, which prevent translocation of β-catenin to the nucleus (from
Tohoku J. Exp. Med.2010, 221, 11–17).
It is believed that inhibition of sFRP-1 would result in vicarious activation of Wnt signaling. In adition, WAY-316606 is a sFRP-1 inhibitor (K
i= 80 nM) that was described to increase total bone area in a murine calvarial organ culture assay at < 1 nM concentration. It is also reported to be antiosteoporotic agent. WAY-262611 is a Wnt pathway agonist that increases bone formation rate with EC
50 of 0.63 uM in TCF-Luciferase assay. WAY-262611 exhibits good pharmacokinetic properties and a dose dependent increase in the trabecular bone formation rate in ovariectomized rats following oral administration. Specific attention needs to be paid to monitoring specific organ toxicity associated with a long-term perturbation of Wnt pathway including neoplasia(s), although recent data suggest otherwise. Current (sub)library size is 1 346 compounds.
