BPN-15477
Based on 1 Customer Validation
BPN-15477 is an orally active, blood-brain barrier-permeable splicing modulator compound (SMC). BPN-15477 restores the correct splicing of exon 20 of the elongator complex protein 1 (ELP1) (EC50 = 1.9 μM), thereby significantly increasing the in vivo functional protein levels in all tissues including the brain. BPN-15477 can be used in the research of familial dysautonomia, such as frontotemporal dementia.

Biological Activity
BPN-15477 (24 h) potently increases the inclusion rate of ELP1 exon 20 in HEK293T cells transfected with Rluc-FD-Fluc, with an EC50 of 1.9 μM[1].
BPN-15477 (0.3-60 μM; 24 h) dose-dependently increases the inclusion rate of ELP1 exon 20 in fibroblasts from FD patients, reaching up to 99.6% after treatment with 60 μM for 24 h[1].
BPN-15477 (30 μM; 7 days) selectively regulates genome-wide transcriptome splicing in wild-type human fibroblasts, altering the inclusion or exclusion of 934 exon triplets after 7 days of treatment at 30 μM, and RT-PCR validates the results of RNA-seq[1].
BPN-15477 (60 μM; 24 h) regulates the splicing of intermediate exons in HEK293T cells transfected with PARP6 and SETD5 minigenes, which is consistent with the prediction results of the CNN model; specifically, treatment with 60 μM for 24 h increases the inclusion rate of PARP6 exons and decreases that of SETD5 exons[1].
BPN-15477 (60 μM; 24-5 days) corrects aberrant splicing in disease-related models: after treatment at 60 μM for 24 to 5 days, it increases the inclusion rate of LIPA exon 8 in fibroblasts from patients with c.894G > A, elevates the inclusion rate of CFTR exon 18 in minigene cells with c.2988G > A, enhances the inclusion rate of MLH1 exon 17 in minigene cells with c.1989G > A, and reduces the inclusion rate of MAPT exon 10 in minigene cells with c.1866 and 16C > T[1].
BPN-15477 (60 μM; 5-7 days) increases the level of functional LIPA protein in fibroblasts from patients with c.894G > A, as well as the level of mature CFTR protein in Flp-In-293 cells expressing the c.2988G > A minigene following treatment with 60 μM for 5 to 7 days[1].
BPN-15477 (0.3-10 μM; 3 days) dose-dependently restores the function of CFTR chloride channels in CFBE cells, with maximal function achieved at a concentration of 3 μM after 3 days of treatment[1].
