Rats treated with oxindole (10-100 mg/kg i.p.), a putative tryptophan metabolite, showed decreased spontaneous locomotor activity, loss of the righting reflex, hypotension, and reversible coma. Brain oxindole levels were 0.05 +/- 0.01 nmol/g in controls and increased to 8.1 +/-

A highly enantioselective alpha-amination of 3-substituted oxindoles with azodicarboxylates catalyzed by a chiral Sc(OTf)(3)/N,N'-dioxide complex (Tf: triflate) has been developed and affords the corresponding 3-amino-2-oxindole derivatives in high yields (up to 98%) with excellent enantioselectivities (up to 99% ee).

An enantioselective direct α-alkylation of 2-oxindoles with Michler's hydrol via an S(N)1-type pathway in the non-covalent activation mode using the bis-cinchona alkaloid and Brønsted acid as a co-catalyst was developed and good to high yields and enantioselectivities were obtained.
Oxindole in pathogenesis of hepatic encephalopathy.
It has previously been shown that the neurodepressant L-tryptophan metabolite oxindole is increased in the blood and brain of rats with fulminant hepatic failure and in the blood of cirrhotic patients affected by chronic hepatic encephalopathy. In the present investigation
