CDK9 inhibitor is a small-molecule selective inhibitor of CDK9 (cyclin dependent kinase 9) with IC50 value of 39 nM [1].
CDKs are a group of serine/threonine kinases and are widely spread in all known eukaryotes. CDKs are activated through binding to cyclins and forming heterodimers. In the dimer, CDK acts as a catalytic subunit and phosphorylates the down-stream proteins such as nuclear lamina protein, nucleolin and histone H1. Through this way, CDKs take participate in the cell cycle regulation. CDK9 is a special member of the CDK family. It can affect the elongation phase of transcription through phosphorylating RNA polymerase II. The partner of it is positive elongation factor b (P-TEFb). It is reported that CDK9 is necessary for the infection of many kinds of viruses such as HIV-1 and HSV1 [1].
CDK9 inhibitor is a 4-aminophenyl derivative based on the (6-phenyl-pyrimidin-4-yl)-phenylamine structure. It showed elevated selectivity against CDK9 than the previous found inhibitors. The IC50 values of CDK9 inhibitor for CDK1/CycB, CDK2/CycE, CDK3/CycE, CDK4/CycD1, CDK5/p35, CDK6/CycD1 and CDK7/CycH are all higher than 1 μM. CDK9 inhibitor has no cytotoxicity. The treatment of CDK9 inhibitor at concentrations of 1 μM and 2 μM resulted in the cell viabilities of 101% and 115%, respectively. It also showed no significant toxicity in H9 cells. In the p24 assay, CDK9 inhibitor exerted its potency in inhibiting HIV-1 propagation with about 10% reduction of p24 production [1].

Applications |
In HIV-1 infected MT4 cells, CDK9 Inhibitor at 2.5 μM potently inhibited HIV-1 propagation due to positive elongation factor b (P-TEFb) inhibition. Moreover, in MT4 cells, CDK9 Inhibitor at the concentrations of 1 μM and 2 μM resulted in the cell viabilities of 101% and 115%, respectively, which implied CDK9 Inhibitor had no cytotoxicity. In the p24 assay, CDK9 Inhibitor down-regulated the expression of p24 protein by 10%. |

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
