Description: SNS-032, also known as BMS-387032, is a 2-aminothiazole-derived, small-molecule cyclin dependent kinase (CDK) inhibitor with potential antineoplastic activity. CDK inhibitor SNS-032 selectively binds to CDKs 2, 7, and 9, preventing their phosphorylation and activation; inhibition of CDK activity may result in cell cycle arrest, the induction of apoptosis and decreased tumor cell proliferation in susceptible tumor cell populations. This agent has been shown to sensitize radioresistant tumor cells to ionizing radiation.

| Biological target: | SNS-032 (BMS-387032) is a potent and selective inhibitor of CDK2, CDK7, and CDK9 with IC50s of 38 nM, 62 nM and 4 nM, respectively |
| In vitro activity: | The aim of the study was to characterize the effects in vitro of SNS-032. Since there is an autocrine/paracrine stimulation of insulinlike growth factor-1 receptor (IGF-1R) in AML cells, which contribute to activation of PI3K signaling , we determined the protein expressions of IGF-1R and class I PI3K isoforms after a 6-hour exposure to increasing concentrations of SNS-032 (Figure 5A). The expression of IGF-1R and p110δ was inhibited by SNS-032 in a dose-dependent fashion. In contrast, p110α protein levels were not changed. The mRNA expression of IGF-1R and p110δ (PIK3CD) was also assessed following treatment with SNS-032 for 6 h using quantitative PCR. IGF-1R and p110δ mRNA expression were significantly inhibited by the drug (Figure 5B), suggesting posttranslational effects of SNS-032 on these target proteins. To investigate whether the suppression of IGF-1R and cell death induced by SNS-032 could be causally related, the effects of IGF-1 on SNS-032-induced cell death were examined. As shown in Figure 5C, exposure of cells to 100 ng/mL IGF-1 did not reverse SNS-032-mediated cellular inhibition. In agreement with this result, addition of IGF-1 also did not change inhibition of SNS-032 on phosphorylation of mTOR at both Ser2448 and Ser2481 even though IGF-1 alone upregulated expression of phosphor-mTOR (Figure 5D). These data supported the hypothesis that SNS-032 might directly target mTORC1/mTORC2 pathway J Hematol Oncol. 2013; 6: 18. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3599109/ |
| In vivo activity: | The in vivo antitumor effect of SNS-032 was evaluated in NOD-SCID mice bearing Omm1 xenografts subcutaneously injected. When the tumor xenografts were grown to ~ 100 mm3, the mice were randomly separated into two groups (n = 8 each) and received treatment with vehicle (PBS) or SNS-032 (15 mg/kg/day, i.p.) for 14 days. The tumor growth curve (tumor volume versus time) was significantly inhibited by SNS-032 administration (Fig. 3a). The tumor size was much smaller in SNS-032-treated group (Fig. 3b). In addition, the tumor weight was lighter in SNS-032-treated mice than vehicle-treated control ones (Fig. 3c). Furthermore, detection of proliferation marker Ki67 by IHC staining showed that the proliferation of UM cells was impaired by SNS-032 treatment (Fig. 3d). Moreover, the expression of active caspase-3 was increased in tumor tissues upon SNS-032 treatment (Fig. 3d). Cell lysates from four tumors each group were detected by Western blot analysis with the indicated antibodies. The results showed that SNS-032 inhibited the CTD phosphorylation of RNA Pol II at Ser2, 5 and 7 sites; the expression and phosphorylation at Ser127 of YAP; as well as the expression of apoptosis-related protein survivin in tumor tissues (Fig. 3e), which were consistent with the in vitro findings. No obvious side effects were observed during the treatment. Similar results were observed in MP41 PDX model which recapitulates the characteristics of human UM (Fig. 3f-j). These results demonstrate that SNS-032 inhibits the growth of UM cells in vivo. Mol Cancer. 2019; 18: 140. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6745806/ |

SNS-032 selectively inhibits CDK2, CDK7, and CDK9. CDK2 and CDK7 are active in cell-cycle progression. CDK7 is also active in promoting transcription, as is CDK9. SNS-032 therefore has dual mechanisms of action-inhibiting proliferation by blocking replication, and inducing apoptosis by blocking transcription to turn off survival and growth factors.
