体外研究 (In Vitro) | Neflamapimod (VX-745) exhibits PBMC IL-1β and TNFα IC50values of 45 and 51 nM, respectively. Neflamapimod is also effective in whole blood, blocking IL-1β and TNFα release with IC50values of 150 and 180 nM, respectively[1]. Neflamapimod shows a promising selectivity profile, with 20-fold selectivity for p38α over p38β (Ki=220 nM)[1]. Neflamapimod (VX-745) solutions in DMSO/DMEM inhibits the IL-6 production with IC50of 15±9 nM[2]. Neflamapimod (VX-745; 5.0 nM) displays potent activity and 1000-fold selectivity over closely related kinases, including ERK1, JNK1-3 and MK2. Neflamapimod (10 nM-50 μM) increasingly inhibits the anisomycin-induced activity of p38α[3]. Neflamapimod (VX-745; 0.06 μM-20 μM) inhibits IL-6 and VEGF secretion in BMSCs. Neflamapimod can inhibit cytokine (TNF-α, IL-6, VEGF)-induced paracrine MM cell growth, survival, and drug resistance in the BM microenvironment. Neflamapimod induces modest growth inhibition of MM.1S, RPMI8226, and U266 cell lines in a dose-dependent fashion, with inhibitory concentration of 50% (IC50) of 10 μM[4].

体内研究 (In Vivo) | Neflamapimod (VX-745; 2.5, 5, and 10 mg/kg) improves the inflammatory scores in mice by 27%, 31%, and 44%, respectively[1]. Neflamapimod (VX-745; 1.06 mg/kg) significantly decreases the inflammation score from 2.07±0.29 for the control group to 1.42±0.06[2].
