exportin 1

Leptomycin B (LMB) 是一种抗真菌抗生素，可阻断真核细胞周期，抑制蛋白出核转运。Leptomycin 通过半胱氨酸残基处的共价修饰使 CRM1 exportin 1失活。

KPT-251 是一种选择性核输出抑制剂。

Eltanexor (ONO-7706) 是一种具有口服活性的 exportin-1 (XPO1) 抑制剂。它具有有效的抗白血病活性。 Eltanexor 通过直接靶向 XPO1 抑制 XPO1 依赖性核输出 (EC50=60.9 nM)。 Eltanexor 在一组白血病细胞系中引起半胱天冬酶依赖性细胞凋亡。

Leptomycin A, a metabolite derived from Streptomyces, acts as an inhibitor of CRM1 (exportin 1) and effectively suppresses HIV-1 replication. Compared to Leptomycin B, it exhibits lesser potency. Leptomycin A hampers the interaction between CRM1 and nuclear export signals, effectively hindering the nuclear export of a wide array of proteins.

Leptomycin B (GMP)是 Leptomycin B 的 GMP 级别试剂。Leptomycin B 是一种抗真菌抗生素，可阻断真核细胞周期，抑制蛋白出核转运。Leptomycin B (GMP) 通过半胱氨酸残基处的共价修饰使 CRM1 exportin 1失活。

LFS-829 is a a small-molecule antagonist of exportin-1. LFS-829 showed low-range nanomolar activities. Oral administration of LFS-829 can significantly reverse the pathological features of colitis model mice. LFS-829 can attenuate dual NF-κB signaling and the Nrf2 cytoprotection pathway via targeting exportin-1 in colitis mice. Moreover, LFS-829 has a very low risk of cardiotoxicity and acute toxicity. LFS-829 holds great promise for the treatment of colitis and may warrant translation for use in clinical trials.
