Adaptive resistance of myeloma to proteasome inhibition represents a clinical challenge, whose biology is poorly understood. Proteasome mutations were implicated as underlying mechanism, while an alternative hypothesis based on low activation status of the unfolded protein response was recently suggested (IRE1/XBP1-low model). We generated bortezomib- and(More)
In the search of a potential backup for clopidogrel, we have initiated a HTS campaign designed to identify novel reversible P2Y12 antagonists. Starting from a hit with low micromolar binding activity, we report here the main steps of the optimization process leading to the identification of the preclinical candidate SAR216471. It is a potent, highly(More)
Proteasome inhibitor (PI) carfilzomib (CFZ) has activity superior to bortezomib (BTZ) and is increasingly incorporated in multiple myeloma (MM) frontline therapy and relapsed settings. Most MM patients ultimately experience PI-refractory disease, an unmet medical need with poorly understood biology and dismal outcome. Pharmacologic targeting of ABCB1(More)
Stem cell biology is one of the most exciting subjects in life science nowadays. The major point in stem cell biology is the extraordinary capacity of these cells to self-renew and to give rise to different cell types. Nevertheless, major issues remain to be cleared and very few diseases can actually be cured based on stem cell therapy. Adult stem cells(More)
EDO-S101 is a first-in-class alkylating, histone deacetylase inhibitor (HDACi) fusion molecule with dual activity. It structurally combines the strong DNA damaging effect of bendamustine with a fully functional pan-HDAC inhibitor, vorinostat (Supplementary Figure S1) that is intended to simultaneously deliver DNAdamaging activity while inhibiting DNA repair(More)
