生物活性    
TMP269 is a novel and selective class IIa histone deacetylase (HDAC) inhibitor with IC50s of 157 nM, 97 nM, 43 nM and 23 nM for HDAC4, HDAC5, HDAC7 and HDAC9, respectively.

体外研究
(In Vitro)    
TMP269 has no impact on the mitochondrial activity and/or the viability of human CD4+ T cells at 10 μM, and may be used as tools to identify the endogenous substrates of the class IIa HDAC enzymes[1]. In IEC-18 intestinal epithelial cells, TMP269 prevents cell cycle progression, DNA synthesis, and proliferation induced in response to G protein-coupled receptor/PKD1 activation[2]. As with HDAC4 knockdown, TMP269 significantly enhances cytotoxicity induced by CFZ in MM cell lines, upregulating ATF4 and CHOP and inducing apoptosis. TMP269 does not hyperacetylate histone H3K9 or α-tubulin in MM cell lines, confirming that it has no inhibitory effects on class I or IIb HDACs. In a dosedependent manner, TPM269-induced cytotoxicity is associated with cleavage of caspase-8, -9, -3 and PARP, consistent with apoptosis[3].

体内研究
(In Vivo)    
In vivo angiogenesis assay, MDA-MB-231 cells are mixed with growth factor-reduced Matrigel and implanted subcutaneously into the flanks of nude mice. TMP269 (subcutaneous injection; 15 mg/kg; every other day; 10 days) shows an obvious antiangiogenic effect with 76% inhibition of angiogenesis in mice[4].
