  Synthesis and Biological Investigation of Oxazole Hydroxamates as Highly Selective Histone Deacetylase 6 (HDAC6) Inhibitors

  摘要：

  Histone deacetylase 6 (HDAC6) catalyzes the removal of an acetyl group from lysine residues of several nonhistone proteins. Here we report the preparation of thiazole-, oxazole-, and oxadiazole-containing biarylhydroxamic acids by a short synthetic procedure. We identified them as selective HDAC6 inhibitors by investigating the inhibition of B recombinant HDAC enzymes and the protein acetylation in cells by Western blotting (tubulin vs histone acetylation). The most active compounds exhibited nanomolar potency and high selectivity for HDAC6. For example, an oxazole hydroxamate inhibits HDAC6 with an IC50 of 59 nM and has a selectivity index of >200 against HDAC1 and HDAC8. This is the first report showing that the nature of a heterocycle directly connected to a zinc binding group (ZBG) can be used to modulate subtype selectivity and potency for HDAC6 inhibitors to such an extent. We rationalize the high potency and selectivity of the oxazoles by molecular modeling and docking.

  The invention relates to compounds of formula I wherein R is hydrogen or lower alkyl; R1 is -(CH2)n-(O)o-heterocycloalkyl or -C(O)-heterocycloalkyl, wherein the heterocycloalkyl group is optionally substituted by lower alkyl, hydroxy, halogen or by -(CH2)p-aryl; n is 0, 1 or 2; o is 0 or 1; p is 0, 1 or 2; R2 is CF3, cycloalkyl, optionally substituted by lower alkoxy or halogen, or is indan-2-yl, or is heterocycloalkyl, optionally substituted by heteroaryl, or is aryl or heteroaryl, wherein the aromatic rings are optionally substituted by one or two substituents, selected from lower alkyl, halogen, heteroaryl, hydroxy, CF3, OCF3, OCH2CF3, OCH2-cycloalkyl, OCH2C(CH2OH)(CH2C1)(CH3), S-lower alkyl, lower alkoxy, CH2-lower alkoxy, lower alkinyl or cyano, or by-C(O)-phenyl, -O-phenyl, -O- CH2-phenyl, phenyl or -CH2-phenyl, and wherein the phenyl rings may optionally be substituted by halogen, -C(O)-lower alkyl, -C(O)OH or -C(O)O-lower alkyl, or the aromatic rings are optionally substituted by heterocycloalkyl, OCH2-oxetan-3-yl or O-tetrahydropyran-4-yl, optionally substituted by lower alkyl; X is a bond, -NR'-, -CH2NH-, -CHR''-, -(CHR'')q-O-, -O-(CHR'')q- or -(CH2)2-; Y is a bond or -CH2- R' is hydrogen or lower alkyl, R'' is hydrogen, lower alkyl, CF3, lower alkoxy, q is 0, 1, 2 or 3; or to a pharmaceutically suitable acid addition salt thereof. It has now been found that the compounds of formula I have a good affinity to the trace amine associated receptors (TAARs), especially for TAAR1. The compounds may be used for the treatment of depression, anxiety disorders, bipolar disorder, attention deficit hyperactivity disorder (ADHD), stress-related disorders, psychotic disorders such as schizophrenia, neurological diseases such as Parkinsons disease, neurodegenerative disorders such as Alzheimers disease, epilepsy, migraine, hypertension, substance abuse and metabolic disorders such as eating disorders, diabetes, diabetic complications, obesity, dyslipidemia, disorders of energy consumption and assimilation, disorders and malfunction of body temperature homeostasis, disorders of sleep and circadian rhythm, and cardiovascular disorders.
