The present disclosure provides small molecule drugs and pharmaceutical compositions for the treatment and prevention of diseases related to the formation of Aβ42 oligomers in a subject. It further provides a method of reducing formation of or disrupting Aβ42 oligomers in a subject, the method comprising the step of administering to the subject in need thereof a therapeutically effective amount of a pharmaceutical composition. One such compound is a compound of formula 120: ##STR00001##

A compound of formula (I) or a salt thereof are provided:

##STR00001##

wherein R.sup.1, X and R.sup.3 are defined in the specification, useful in the treatment of disorders mediated by KMO such as acute pancreatitis, chronic kidney disease, other conditions associated with systemic inflammatory response syndrome (SIRS), Huntington's disease, Alzheimer's disease, spinocerebellar ataxias, Parkinson's disease, AIDS-dementia complex, amylotrophic lateral sclerosis (ALS), depression, schizophrenia, sepsis, cardiovascular shock, severe trauma, acute lung injury, acute respiratory distress syndrome, acute cholecystitis, severe burns, pneumonia, extensive surgical procedures, ischemic bowel, severe acute hepatic disease, severe acute hepatic encephalopathy or acute renal failure.

A compound of formula (I) or a salt thereof are provided:
