AR-42 is an orally active inhibitor of histone deacetylases (HDACs) in clinical trials for multiple myeloma, leukemia, and lymphoma. It has few hydrogen bond donors and acceptors but is a chiral 2-arylbutyrate and potentially prone to racemization. We report achiral AR-42 analogues incorporating a cycloalkyl group linked via a quaternary carbon atom, with up to 40-fold increased potency against human class I HDACs (e.g., JT86, IC50 0.7 nM, HDAC1), 25-fold increased cytotoxicity against five human cancer cell lines, and up to 70-fold less toxicity in normal human cells. JT86 was ninefold more potent than racAR-42 in promoting accumulation of acetylated histone H4 in MM96L melanoma cells. Molecular modeling and structure-activity relationships support binding to HDAC1 with tetrahydropyran acting as a hydrophobic shield from water at the enzyme surface. Such potent inhibitors of class I HDACs may show benefits in diseases (cancers, parasitic infections, inflammatory conditions) where AR-42 is active.

This invention pertains to certain carbamic acid compounds of the formula (I), which inhibit HDAC (histone deacetylase) activity: wherein: J is a linking functional group and is independently: -O-C(=O)- or -C(=O)-O- or - C(=O)-; Cy is a cyclyl group and is independently: C3-20carbocyclyl, C3-20heterocyclyl, or C5-20aryl; and is optionally substituted; Q1 is a cyclyl leader group, and is independently a divalent bidentate group obtained by removing two hydrogen atoms from a ring carbon atom of a saturated monocyclic hydrocarbon having from 4 to 7 ring atoms, or by removing two hydrogen atoms from a ring carbon atom of saturated monocyclic heterocyclic compound having from 4 to 7 ring atoms including 1 nitrogen ring atom or 1 oxygen ring atom; and is optionally substituted; Q2 is an acid leader group, and is independently: C1-8alkylene; and is optionally substituted; or: Q2 is an acid leader group, and is independently: C5-20arylene; C5-20arylene-C1-7alkylene; C1-7alkylene-C5-20arylene; or C1-7alkylene-C5-20arylene-C1-7alkylene; and is optionally substituted; and pharmaceutically acceptable salts, solvates, amides, esters, ethers, chemically protected forms, and prodrugs thereof. The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, to inhibit HDAC,and in the treatment of conditions mediated by HDAC, cancer, proliferative conditions, psoriasis, etc.
