The present invention provides a compound for treating or preventing diseases caused by mitochondrial hyperfission.

The present invention provides a compound represented by formula (1):

##STR00001## wherein R.sub.1 and R.sub.1 are each independently hydrogen, an optionally substituted lower alkyl, an optionally substituted lower cycloalkyl, and the like; R.sub.2 is an optionally substituted lower alkyl, an optionally substituted lower cycloalkyl, and the like; R.sub.3 and R.sub.4 are each independently hydrogen, halogen, hydroxy, nitro, cyano, an optionally substituted lower alkyl, and the like; R.sub.5 and R.sub.6 are each independently an optionally substituted lower alkyl; an optionally substituted lower cycloalkyl, and the like; X is nitrogen or oxygen; Y is carbon, nitrogen or oxygen; and a broken line represents the presence or absence of a bond; or a pharmaceutically acceptable salt, a solvate, or a prodrug thereof.

Ketamine derivatives and pharmaceutical compositions thereof are disclosed. When administered orally the ketamine derivatives provide increased bioavailability of ketamine in the systemic circulation. The ketamine derivatives can be used to treat neurological diseases, psychological diseases and pain.

Disclosed herein are compounds for activating the Reelin signaling system for the treatment of neurological disorders. Further provided are compounds and methods for activating a lipoprotein receptor, such as ApoER2 or VLDLR.
