Prodrugs of hydroxamate-based GCPII inhibitors and methods of their use for treating a disease or condition are disclosed.

Prodrugs of hydroxamate-based GCPII inhibitors and methods of their use for treating a disease or condition are disclosed.

The present invention provides compounds of formula (I): ##STR00001##
or a pharmaceutically acceptable salt, solvate, or prodrug thereof, wherein W, X, n, s, t, and R.sup.a are as described herein. The present invention relates generally to selective inhibitors of histone deacetylase and to methods of making and using them.

The present disclosure describes novel compounds of the general Formula (I), their analogs, tautomeric forms, stereoisomers, polymorphs, hydrates, solvates, pharmaceutically acceptable salts, pharmaceutical compositions, metabolites, and prodrugs thereof. These compounds can inhibit both LSD and HDAC and are useful as therpeautic or ameliorating agent for diseases that are involved in cellular growth such as malignant tumors, schizophrenia, Alzheimer's disease, parkinson's disease and the like.

Triterpenoid derivatives and compositions comprising said triterpenoids derivatives of Formula (I) are described, wherein RC(O)NHOH. Said triterpenoids and compositions show capacity to bind PHD2, stabilize HIF-1 and HIF-2 proteins, activate the HIF pathway in different cell types, induce angiogenesis in human endothelial vascular cell, show neuroprotective activity in vitro and in vivo, antidiabetic activity and reduce the levels of lipids in vivo, and increase the plasma levels of Erythropoietin in vivo. The triterpenoid derivatives described act also in a selective manner and do not induce Nrf2 activation, NF-B inhibition, STAT3 inhibition, and TGR5 activation, which are known activities of the natural triterpenoid precursors. Said triterpenoid derivatives are useful in the treatment of conditions and diseases which are responsive to HIF activation such as stroke, cerebral palsy, traumatic injuries and neurodegenerative diseases; and also IBD, myocardial ischaemia-reperfusion injury, acute lung injury, diabetic and chronic wounds, organ transplantation, acute kidney injury or arterial diseases. ##STR00001##
