| Bioactivity | SRI-37240 is a potent premature termination codons (PTCs) inhibitor. SRI-37240 suppresses CFTR nonsense mutations. SRI-37240 alters cellular translation termination at PTCs in HEK293T cells. SRI-37240 can also restore CFTR function in primary bronchial epithelial cells when combination with G418[1]. | ||||||||||||
| Target | Premature termination codons, CFTR | ||||||||||||
| Invitro | SRI-37240 (1, 3, 10 and 30 µM; 48 h) induces concentration-dependent increases in CFTR-dependent (Forskolin-stimulated and sensitive to the inhibitor CFTRInh-172) chloride conductance[1].SRI-37240 (10 µM; 72 h) significantly increases the amount of full-length, fully glycosylated form of CFTR protein, and the unprocessed, immature form of full-length CFTR protein in 16HBEge cells when co-treated with G418 (100 µM)[1].SRI-37240 (10 µM; 24 h) alters cellular translation termination at PTCs in HEK293T cells, also increases global densities of ribosomes at normal stop codons without affecting densities of ribosomes in 3-UTRs[1].SRI-37240 (10 µM; 72 h) restores CFTR function in primary bronchial epithelial cells when combination with G418[1].
