Description: SGC-CBP30 is a potent and selective inhibitor of CREBBP (CBP) and EP300; which are general transcriptional co-activators. CREBBP has also been associated with Amyotrophic Lateral Sclerosis (ALS) or Lou GehrigÂ’s disease, a neurodegenerative disease with progressive degeneration of motor neurons in the brain and spinal cord, Alzheimer's disease and poly glutamine repeat diseases such as Spinal and Bulbar Muscular Atrophy and HuntingtonÂ’s disease.

| Biological target: | SGC-CBP30 is a potent and highly selective CBP/p300 bromodomain (Kds of 21 nM and 32 nM for CBP and p300, respectively) inhibitor, displaying 40-fold selectivity over the first bromodomain of BRD4 [BRD4(1)] bound. |
| In vitro activity: | In order to know whether SGC-CBP30 treatment has an effect on IL6 autocrine secretion in XG1LenRes cells, we measured IL6 in the culture media of XG1LenRes in the absence and presence of drug treatment. As shown in Fig,6c, SGC-CBP30 treatment reduced IL6 autocrine production from XG1LenRes in either the absence or presence of lenalidomide. Accordingly, STAT3 activation was inhibited by SGC-CBP30 treatment (Fig.6b). Finally, we demonstrated that SGC-CBP30 also increased the sensitivity to lenalidomide in three IMiD-sensitive HMCLs (supplementary Figure 9D–F). SGC-CBP30 treatment could change the chromatin structure in the IRF4 and MYC regulatory regions or regulate other genes in IMiDs-mediated activity, therefore inducing increased sensitivity to IMiD-induced signals (such as downregulation of IKZF1/IKZF3).

| In vivo activity: | Lung injury in septic mice was characterized by alveolar septal thickening, extensive edema, massive infiltration of inflammatory cells, and alveolar congestion/collapse. In lungs from the SGC-CBP30-8 h therapy group, LPS- or CLP-induced histopathological damage and accumulation of inflammatory cells were attenuated (Figures 2A, B, first-line). Semi-quantitative assessment of lung histology revealed that administration of SGC-CBP30 at 8 h following LPS or CLP significantly decreased tissue injury in the lung, similar to the positive control DEX-0.5 h. In the SGC-CBP30-8 h treatment group, infiltrated inflammatory cells were significantly reduced and liver architecture was significantly improved (Figures 2A, B, third-line). As shown in Semi-quantitative statistics, administration of SGC-CBP30 at 8 h or DEX at 0.5 h after septic modeling markedly reduced liver injury scores. It is clear that the delayed SGC-CBP30 administration at 8 h significantly attenuated the histopathological deterioration and inflammatory cell infiltration in renal tissues. Together, these results demonstrate that selective CBP bromodomain inhibitors such as SGC-CBP30 may be effective not only to suppress inflammatory response in organs, but also to ameliorate organ injury caused by LPS-induced endotoxemia and CLP-induced sepsis.

CREBBP (CBP) and EP300 are involved in many biological processes like maintenance of genomic stability by affecting DNA replication and DNA repair as well as cell growth, transformation and development. They also play and essential role in neuronal plasticity/ memory formation hematopoiesis and energy homeostasis as demonstrated in a variety of mouse models. They possess both acetyl-transferase enzymatic and bromodomain containing regions. Through acetylation of non-histone proteins CREBBP can have a positive or negative effect on transcriptional regulation by affecting protein- protein interactions, protein-DNA interactions, nuclear retention or protein half-life.
