The present disclosure is related to the field of enzyme inhibitors, and in particular to a hydroxamic acid derivative, a method for producing the same and use thereof. The hydroxamic acid group of the hydroxamic acid derivative can be chelated with zinc ions in the LpxC active area, and the derivative has a hydrophobic side chain which can bind to hydrophic channels in the enzyme LpxC. These guarantee that the hydroxamic acid derivative has good bactericidal activity against Gram-negative bacteria and low toxicity. The present disclosure also provides a method for producing the hydroxamic acid derivative, which requires a shorter reaction time and can provide the derivative with a high yield.

The present invention relates to compounds of formula (I):

##STR00001##

or a pharmaceutically acceptable salt, hydrate, solvate, or prodrug thereof, wherein U, J, V, X, R.sup.1a, R.sup.2b, R.sup.2c, R.sup.5 and t are as described herein. The present invention relates generally to inhibitors of histone deacetylase and to methods of making and using them. These compounds are useful for promoting cognitive function and enhancing learning and memory formation. In addition, these compounds are useful for treating, alleviating, and/or preventing various conditions, including for example, neurological disorders, memory and cognitive function disorders/impairments, extinction learning disorders, fungal diseases and infections, inflammatory diseases, hematological diseases, and neoplastic diseases in humans and animals.
