“…HDACi have also been combined with several inhibitors of known targets. Combination of PAN with some of the compounds listed in Table 3, such as A-1331952, AZD6244, cyclosporine A (CsA), everolimus (EVL), NVP-AUY922, picropodophyllin (PPP), pterostilbene (Pter), RAD001, S63845, tacrolimus (FK506), venetoclax (Ven) and zolendronic acid (ZOL), led to decreased proliferation in various MM cells, 35,78,80,81,83,[85][86][87][88] including patientderived cells, which was synergistic in some cases 78,80,81,83,[85][86][87][88] (Table 2). Interestingly, decreased proliferation was also seen in MM.1S cells co-cultured with BMSCs, in the presence of PAN and AZD6244, as well as PAN and RAD001, suggesting that the BM microenvironment could not stimulate proliferation, while no effect of the combination was observed in BMSCs alone.…”
