The invention relates to acid addition salts of piperazine derivatives, as well as solid forms, such as polymorphic forms, thereof, which are useful as pharmaceutical ingredients and in particular as glycosidase inhibitors.
Provided are: useful novel compounds that exhibit antibacterial activity based on their actions for inhibiting GyrB of DNA gyrase and ParE of topoisomerase IV; and 2(1H)-quinolinone derivatives represented by formula [1]:
or pharmaceutically acceptable salts thereof.
Provided herein are compounds of the formula (I):
as well as pharmaceutically acceptable salts thereof, wherein the substituents are as those disclosed in the specification. These compounds, and the pharmaceutical compositions containing them, are useful for the treatment of diseases such as, for example, obesity, type II diabetes mellitus and metabolic syndrome.
Compounds of formula (I), and salts and pro-drugs thereof: Formula (I) wherein for example R
1
is optionally substituted aryl or heteroaryl; Y is a linking group selected from, for example, a direct bond, and a (substituted) alkyl chain; R
2
is an optionally substituted aryl, an optionally substituted cycloalkyl or an optionally substituted heterocyclic group; are described. Processes to make such compounds and their use as DGAT inhibitors, for example in the treatment of obesity, are also described.
