生物活性

QL-X-138 is a potent and selective BTK/MNK dual kinase inhibitor, exhibits covalent binding to BTK and non-covalent binding to MNK. QL-X-138 shows IC50s of 9.4 nM, 107.4 nM and 26 nM for BTK, MNK1 and MNK2 kinases respectively. QL-X-138 also shows anti-dengue virus 2 activity, with an IC50 of 3.5 μM. QL-X-138 can be used for the research of B-cell malignancies[1][2].

体外研究
(In Vitro)

QL-X-138 (72 h) exhibits anti-proliferation activity against lymphoma and leukemia cell lines, with an GI50s of 0.31, 1.2, 0.49,1.4, 0.4, 0.23, 0.95, 1.2, 1.4, 0.23, 1.3, 0.93, 1, and 2.4 μM for TMD8, U2932, Ramos, OCI-AML3, SKM-1, NOMO-1, NB4, HEL, U937, NALM6, MEC-1, MEC-2, Hs 505.T and REC-1 cells, respectively[1].
QL-X-138 (0.5-5 μM; 24-72 h) arrests the progression of Ramos, OCI-AML-3, U937 and U2932 cells cycle in a dose dependent manner[1].
QL-X-138 (0.5-5 μM; 8-72 h) induces apoptosis of Ramos, OCI-AML-3, U937 and U2932 cells in a time- and dose-dependent manner[1].
QL-X-138 (3-10000 nM; 4 h) blocks BTK- and MNK-mediated signaling in lymphoma and leukemia cell[1].

Shanghai Jinpan Biotech Co Ltd has not independently confirmed the accuracy of these methods. They are for reference only.
