Tankyrase 1/2 Inhibitor VI, G007-LK-Calbiochem

半岛bd体育手机客户端 说明

一般描述

A cell-permeable, triazolyl-vinyl-oxadiazole compound that targets adenosine site of the NAD⁺pocket in the TNKS PARP domain and acts as a potent and highly selective tankyrase inhibitor (IC₅₀= 33 and 26 nM, respectively, against TNKS1/PARP5a/ARTD5 and TNKS2/PARP5b/ARTD6 in auto-PARsylation assays), effectively inhibiting murine Wnt3a-induced reporter activity in human HEK293 and murine 10T1/2 cultures (IC_max~300 and 600 nM, respectively). Shown to display little or no inhibitory potency (IC₅₀>10 ?M) toward 7 other PARP enzymes (PARP1, 2, 3, 6, 7,10,11), 90 kinases, 16 phosphatases, and 75 GPCRs (IC₅₀>10 ?M). Shown to inhibit two CRC lines, COLO-320DM & SW403, colony formationin vitro(200 nM) and tumor expansion in micein vivo(20 mg/kg via daily i.p.), although G007-LK toxicity is observed at higher dosages (≥30 mg/kg/12 h or 60 mg/kg/d via i.p.).

Please note that the molecular weight for this compound is batch-specific due to variable water content.

In addition to being more selective over PARP1/2 (IC₅₀>10 ?M vs 116 nM/47 nM with XAV939) than the nicotinamide site-targeting XAV939 (Cat. No. 575545), G007-LK is also shown to display little or no inhibitory potency (IC₅₀>10 ?M) toward 5 other PARP enzymes (PARP3, 6, 7,10,11), 90 kinases, 16 phosphatases, and 75 GPCRs (IC₅₀>10 ?M). Wnt signaling inhibition upon G007-LK treatment in 11 APC (Adenomatous polyposis coli/deleted in polyposis 2.5/DP2.5) mutatant CRC (colorectal cancer) lines ranges from no effect to varying degrees of partial blockages that do not correlate with the observed CRC colony formation inhibitions.Two CRC lines, COLO-320DM & SW403, whose colony formation are affected by G007-LKin vitro(by 70% and 27%, respectively, at 200 nM in 7 to 13 d) are also inhibited by G007-LK for their tumor expansion in micein vivo(by 47% and 42%, respectively, on d21; 20 mg/kg per daily i.p.), while G007-LK toxicity is observed at high dosages in mice (≥30 mg/kg/12 h or 60 mg/kg/d via i.p.) due to small intestine damage as a result of on-target wnt signaling inhibition in normal tissue. Exhibits favorable pharmacokinetic properties in mice when administered via i.p. ( Plasmat_1/2≥2.73 h;C_max≥2.358 ?g/mL; 5 mg/kg) or p.o. ( Plasmat_1/2≥2.8 h;C_max≥871 ng/mL; 5 mg/kg).
