CRM1-IN-2 (Compound KL2) is a noncovalent inhibitor of CRM1, localizing it to the nuclear periphery, reducing its nuclear presence, and inhibiting its nuclear export function. It effectively inhibits the growth of colorectal cancer cells and induces apoptosis [1].

CRM1-IN-1 (Compound KL1), a noncovalent inhibitor of CRM1, promotes nuclear degradation of CRM1 with an IC50 of 0.27 μM, inhibits CRM1-mediated nuclear export, suppresses cell proliferation, and induces apoptosis in colorectal cancer cells [1].

Leptomycin B (LMB) is a potent inhibitor of the nuclear export of proteins and is a potent antifungal antibiotic blocking the eukaryotic cell cycle. Leptomycin B inactivates CRM1 exportin 1 by covalent modification at a cysteine residue.

CRM1-IN-3 (B28), a noncovalent inhibitor of CRM1, is utilized in the research of protein localization and tumor studies [1].

CRM1 degrader 1 (1l) is a low-toxicity CRM1 degrader that induces apoptosis in gastric carcinoma and selectively inhibits the proliferation of gastric cancer[1].

LFS-1107, a reversible CRM1 inhibitor (Kd: 12.5 pM), selectively targets and eliminates ENKTL cells, offering potential for cancer research applications [1].

XPO1-ligand-1 is a target protein ligand for XPO1, and it can be utilized in the synthesis of PROTAC XPO1 degrader-1.

PROTAC XPO1 degrader-1 (Compound 2c) is an XPO1 degrader. It exhibits anti-proliferative effects, induces apoptosis, inhibits NF-κB activity, and causes cell cycle arrest at the G1 phase. PROTAC XPO1 degrader-1 is applicable to research on hematological malignancies.

Verdinexor (KPT-335) (KPT-335), a specific XPO1 CRM1 inhibitor, are orally bioavailable.

(E)-KPT330 is a CRM1-selective inhibitor of nuclear export. It inhibits protein trafficking from the nucleus and induces cell cycle arrest and apoptosis in mesothelioma cells.

KPT276 (KPT 276) is an orally bioavailable selective inhibitor of nuclear export (SINE) that irreversibly bind to CRM1 and block the function of CRM1.

CBS9106 (SL-801) is a reversible oral CRM1 inhibitor with CRM1 degrading and antitumor activity.CBS9106 inhibits CRM1-dependent nuclear export and reduces CRM1 protein levels.CBS9106 inhibits tumor growth and prolongs the survival of mice bearing tumor xenografts.CBS9106 is an inhibitor of CRM1-dependent nuclear export and reduces CRM1 protein levels.

KPT185 (KPT 185) is a selective CRM1 inhibitor, inducing apoptosis, cell-cycle arrest.

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.

SP100030 analogue 1 (compound 11) is a selective transcription activation (SITA) inhibitor within the SP100030 class, capable of inhibiting XPO1-dependent upregulation of IL2 in a Jurkat-based IL2-Luc reporter assay, with an EC50 of 137 nM.

PKF050-638 inhibits the CRM1-mediated Rev nuclear export by disrupting CRM1-NES interaction. PKF050-638 is an effective and selective inhibitor of HIV-1 Rev (IC50=0.04 μM).

Eltanexor Z-isomer exhibits different inhibitory effects on Z138, MM15, 3T3 cell lines, with IC50s of 100 nM-50 μM, < 100 nM, > 30 μM, respectively.Eltanexor Z-isomer is the less active isomer of KPT-8602. KPT-8602 is a potent CRM1 inhibitor.

AN-988 (compound 6) is a covalent CRM1 inhibitor.

Leptomycin B (GMP) refers to the GMP grade reagents of Leptomycin B. Leptomycin B (LMB) is a potent inhibitor of the nuclear export of proteins and is a potent antifungal antibiotic blocking the eukaryotic cell cycle. Leptomycin B inactivates CRM1 exportin 1 by covalent modification at a cysteine residue.
