A-800141
A-800141 is an orally active, selective, sulfonamide-based MetAP2 inhibitor (IC50=12 nM) that binds reversibly to MetAP2 and interacts with its manganese ions. A-800141 induces the production of N-terminal methionine-unprocessed GAPDH variants, which in turn triggers G1-phase cell cycle arrest, elevates p21 levels, and reduces the levels of phosphorylated Rb and total cyclin A. A-800141 exhibits anti-angiogenic and tumor growth inhibitory effects, and produces synergistic effects when combined with cytotoxic inhibitors or BCL-2 inhibitors. A-800141 has been widely used in scientific research related to B-cell lymphoma, neuroblastoma, prostate cancer, colon cancer, melanoma and other fields.

A-800141 potently inhibits the proliferation of HMVEC, HT1080, HCT116, A549, NCI-H460 and B16F10 cells, and also induces quiescent G1 cell cycle arrest and alters the expression of cell cycle markers in HUVEC[1].
A-800141 (0.0004-3 μM; 48 h) inhibits N-terminal processing of GAPDH in bEND3 cells, with an EC50 of 20 nM in regular medium and 100 nM in medium containing 40 mg/mL HSA[1].
A-800141 (100 nM; 3 d) induces G1 cell cycle arrest in HUVECs and regulates cell cycle regulatory proteins including p21, p53, phosphorylated Rb and cyclin A[2].

Concentration:10 nM, 100 nM, 100 μM

Incubation Time:24 hours, 3 days

Result:Exhibited potent antiproliferative activity across all tested cell lines, with IC50 values of 10 nM (HMVEC), 26 nM (HT1080), 18 nM (HCT116), 25 nM (A549), 11 nM (NCI-H460), and 11 nM (B16F10).
Induced cytostatic G1 phase cell cycle arrest without apoptosis.
Initiated G1 arrest in HUVEC at 10 nM, with a significant increase in G1-phase cells (54% vs. 39% in controls) observed at 100 nM after 24 hours of treatment.
Produced a similar G1 arrest profile in HUVEC at 100 μM with 3 days incubation.
Elevated p21 and modestly increased p53 levels, reduced phosphorylated Rb, and decreased total cyclin A levels in HUVEC.
A-800141 (150 mg/kg per day; p.o.; twice daily; days 14-end) does not significantly inhibit tumor growth as a single agent in a male SCID beige mouse SuDHL4 B cell lymphoma xenograft model, but produces significant tumor inhibition when combined with etoposide[1].
A-800141 (50-200 mg/kg per day; p.o.; twice daily; days 1-14) produces 85% tumor growth inhibition and significant GAPDH processing blockade in both WBCs and tumor tissue in a C57BL/6 mouse B16F10 melanoma model, with efficacy correlating to the degree of MetAP2 inhibition measured by GAPDH variants[1].
A-800141 (75-150 mg/kg; p.o.; daily) achieves 70% growth inhibition of CHP-134 neuroblastoma xenografts in SCID mice with good tolerability[3].
A-800141 (100-150 mg/kg; p.o.; twice daily) causes significant growth delay of PC-3 prostate carcinoma xenografts in SCID mice[3].
