Uses
NMS-P937 is a quinazoline derivative that is a potent and selective Polo-like kinase 1 inhibitor. Antitumor, anti-cancer.
Biological Activity
nms-1286937 (nms-p937) is a potent and selective inhibitor of polo-like kinase 1 (plk1) with ic50 value of 2 nm [1].plk1 is a serine/threonine protein kinase and plays an important role in the cell cycle control machinery. plk1 is involved in mitotic entry, bipolar mitotic spindle formation, centrosome duplication, transition from metaphase to anaphase, maintenance of genomic stability and cytokinesis [1].nms-1286937 is an orally bioavailable plk1 inhibitor. in cell lines established from solid tumors, leukemias and lymphomas, nms-p937 inhibited tumor cell proliferation. in a2780 cells, nms-p937 caused a g2-m cell-cycle block. in the mitotic phase, nms-p937 induced apoptotic death with misaligned chromosomes and an aberrant number of spindles poles [2]. in human osteosarcoma (os) cell lines, nms-p937 inhibited migration and clonogenic ability of cell lines. in abcb1-overexpressing, doxorubicin (dx)-resistant cell lines, combination of nms-p937 and dx reverted dx-resistance by inhibiting abcb1 transport activity [3].in harlan nu/nu mice, nms-p937 exhibited a good pharmacokinetic profile with low clearance, high auc and cmax, and acceptable oral bioavailability. in mice xenografted with human hct116 colon adenocarcinoma cells, nms-p937 (45 mg/kg) inhibited tumor growth by 83% and reduced body weight by 16% [1].

Check Digit Verification of cas no
The CAS Registry Mumber 1034616-18-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,4,6,1 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1034616-18:
(9*1)+(8*0)+(7*3)+(6*4)+(5*6)+(4*1)+(3*6)+(2*1)+(1*8)=116
116 % 10 = 6
So 1034616-18-6 is a valid CAS Registry Number.

As part of our drug discovery effort, we identified and developed 4,5-dihydro-1H-pyrazolo[4,3-h]quinazoline derivatives as PLK1 inhibitors. We now report the optimization of this class that led to the identification of NMS-P937, a potent, selective and orally available PLK1 inhibitor. Also, in order to understand the source of PLK1 selectivity, we determined the crystal structure of PLK1 with NMS-P937. The compound was active in vivo in HCT116 xenograft model after oral administration and is presently in Phase I clinical trials evaluation.
