Santacruzamate A (CAY10683) is a potent and selective inhibitor of histone deacetylase with IC50 values of 0.112 and 433 nM for HDAC2 and HDAC6, respectively [1].
Histone deacetylases (HDACs) are a series of enzymes that remove acetyl groups from an ε-N-acetyl lysine amino acid on a histone and make the histones to wrap the DNA more tightly, which prevent transcription.
Santacruzamate A (CAY10683) is a potent and selective HDAC inhibitor. Natural and synthetic santacruzamate A inhibited HDAC2 with IC50 values of 119 and 112 pM respectively and inhibited HDAC6 with IC50 values of 434 and 433 nM, respectively. Santacruzamate A was 700-fold more potent than SAHA for HDAC2. However, santacruzamate A inhibited HDAC4 with IC50 values of >1 µM. In HCT-116 colon carcinoma cells, natural and synthetic santacruzamate A inhibited cell growth with GI50 values of 29.4 and 28.3 µM, respectively. In HuT-78 cutaneous T-cell lymphoma cells, both inhibited cell growth with GI50 values of 1.4 and 1.3 µM, respectively [1].

Pharmacological or transcriptional inhibition of both HDAC1 and 2 leads to cell cycle blockage and apoptosis via p21(Waf1/Cip1) and p19(INK4d) upregulation in hepatocellular carcinoma.[Pubmed:29484736]
Cell Prolif. 2018 Jun;51(3):e12447.
OBJECTIVES: Histone deacetylases (HDACs) are commonly dysregulated in cancer and represent promising therapeutic targets. However, global HDAC inhibitors have shown limited efficacy in the treatment of solid tumours, including hepatocellular carcinoma (HCC). In this study, we investigated the therapeutic effect of selectively inhibiting HDAC1 and 2 in HCC. METHODS: HDAC1 inhibitor Tacedinaline (CI994), HDAC2 inhibitor Santacruzamate A (CAY10683), HDAC1/2 common inhibitor Romidepsin (FK228) and global HDAC inhibitor Vorinostat (SAHA) were used to treat HCC cells. Cell cycle, apoptosis and the protein levels of CDKs and CDKNs were performed to evaluate HCC cell growth. Inhibition of HDAC1/2 by RNAi was further investigated. RESULTS: Combined inhibition of HDAC1/2 led to HCC cell morphology changes, growth inhibition, cell cycle blockage and apoptosis in vitro and suppressed the growth of subcutaneous HCC xenograft tumours in vivo. p21(Waf1/Cip1) and p19(INK)(4d) , which play roles in cell cycle blockage and apoptosis induction, were upregulated. Inhibition of HDAC1/2 by siRNA further demonstrated that HDAC1 and 2 cooperate in blocking the cell cycle and inducing apoptosis via p19(INK)(4d) and p21(Waf1/Cip1) upregulation. Finally, H3K18, H3K56 and H4K12 in the p19(INK)(4d) and p21(Waf1/Cip1) promoter regions were found to be targets of HDAC1/2. CONCLUSIONS: Pharmacological or transcriptional inhibition of HDAC1/2 increases p19(INK)(4d) and p21(Waf1/Cip1) expression, decreases CDK expression and arrests HCC growth. These results indicated a potential pharmacological mechanism of selective HDAC1/2 inhibitors in HCC therapy.
