CVT-313
CVT-313 is a potent inhibitor of cyclin-dependent kinase 2 (CDK2) with IC50 value of 0.5 μM [1].
CDK2 is a serine/threonine kinase that is essential for the G1-S phase during cell division. CDK2 is an important target for prevention of aberrant cell proliferation [1].
In MRC-5 cells, CVT-313 inhibited Rb hyperphosphorylation in a time-dependant way and the cell cycle was arrested at the G1/S phase. Also, CVT-313 inhibited the growth of mouse, rat and human cells with IC50 values from 1.25 to 20 mM [1]. In human diffuse large B-cell lymphoma (DLBCL) cells, CVT-313 reduced CDK2-mediated phosphorylation of the retinoblastoma gene product (Rb) on T821. Also, CVT-313 reduced the anti-apoptotic factor Myeloid cell leukemia-1 (Mcl-1) and induced apoptosis [2].
In the injured rat carotid artery model of restenosis, CVT-313 (1.25 mg/kg) reduced neointima formation by 80%. Moreover, Treatment animals with CVT-313, the neointimal areas were inhibited by at least 70%. These suggested that CDK2 was an antiproliferative target and CVT-313 is an ideal candidate for the treatment of proliferative diseases [1].

Applications |
CVT-313 inhibited cdk2 in several human DLBCL cells. Incubation of DLBCL cells with 25 μM CVT-313 reduced phosphorylation of endogenous Rb on Thr821. CVT-313 (48 and 72 hr) induced cell apoptosis in human DLBCL cells in a time-dependent manner. CVT-313 treatment did not result in cell cycle arrest at 20 hr or at 48 hr. Treatment of LY3, LY8 cells and LY18 cells with CVT-313 led to parallel changes in XIAP and Mcl-1 mRNA levels. In normal and tumor human/murine cell lines, CVT-313 inhibited cell proliferation with the IC50 ranged from 1.25 to 20 μM. CVT-313 (12.5 μM, 18 h) induced cell arrest at the G1/S and G2/M boundary. In nonsynchronized MRC-5 cells, treatment with CVT-313 (6.25 μM) for 36 h induced a 2 N DNA content. Treatment with CVT-313 (6.25 μM) for 4 or 8 h after serum stimulation inhibited Rb hyperphosphorylation. |

0.75 and 0.25 mg/kg |
|
Application |
In the injured rat carotid artery model of restenosis, lower doses of CVT-313 (0.75 and 0.25 mg/kg) were less efficacious, reducing mean neointimal area by about 30%, whereas the lowest dose tested (0.025 mg/kg) did not achieve any significant reduction in neointimal area. Treatment with CVT-313 for 14 days blocked restenosis in the rat carotid model. |

Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
