Information
AR-42 AR-42 (HDAC-42) is an HDAC inhibitor with IC50 of 30 nM. Phase 1.
In vitro
AR-42 treatment induces histone hyperacetylation and p21WAF/CIP1 overexpression, and inhibits the growth of DU-145 cells with IC50 of 0.11 μM. HDAC42 is potent in suppressing the proliferation of U87MG and PC-3 cells, in part, because of its ability to down-regulate Akt signaling. AR-42 inhibits the growth of PC-3 and LNCaP cells with IC50 of 0.48 μM and 0.3 μM, respectively. Compared to SAHA, AR-42 exhibits distinctly superior apoptogenic potency, and causes markedly greater decreases in phospho-Akt, Bcl-xL, and survivin in PC-3 cells. AR-42 treatment induces growth inhibition, cell- cycle arrest, apoptosis, and activation of caspases-3/7 in malignant mast cell lines. AR-42 treatment induces down-regulation of Kit via inhibition of Kit transcription, disassociation between Kit and heat shock protein 90 (HSP90), and up-regulation of HSP70. AR-42 treatment down-regulates the expression of p-Akt, total Akt, phosphorylated STAT3/5 (pSTAT3/5), and total STAT3/5. AR-42 potently inhibits the growth of JeKo-1, Raji, and 697 cells with IC50 of <0.61 μM. AR-42 also sensitizes CLL cells to TNF-Related Apoptosis Inducing Ligand (TRAIL), potentially through reduction of c-FLIP. AR-42 treatment also induces autophagy through downregulation of Akt/mTOR signaling and inducing ER stress in hepatocellular carcinoma (HCC) cells.
In vivo
The growth of PC-3 tumor xenografts is suppressed by 52% and 67% after treatment with AR-42 at 25 mg/kg and 50 mg/kg, respectively, whereas SAHA at 50 mg/kg suppresses growth by 31%. In contrast to mice treated with SAHA, intratumoral levels of phospho-Akt and Bcl-xL are markedly reduced in AR-42 treated mice. In the transgenic adenocarcinoma of the mouse prostate (TRAMP) model, administration of AR-42 not only decreases the severity of prostatic intraepithelial neoplasia (PIN) and completely prevents its progression to poorly differentiated carcinoma, but also shifts tumorigenesis to a more differentiated phenotype, suppressing absolute and relative urogenital tract weights by 86% and 85%, respectively. AR-42 significantly reduces leukocyte counts, and prolongs survival in three separate mouse models of B-cell malignancy without evidence of toxicity.
