The thiocyanate cleavage of the Nα-o-nitrophenylsulfenyl group from peptides in solution or on a solid support proceeds effectively in the presence of (2-methyl-1-indolyl)acetic acid.This scavenger was prepared from 2-methylindole and sodium br

1,3-Indandiones VIII. 2-Hydroxy-2-indolyl-1,3-indandiones, 2-(indol-3-ylmethylene indandione and derivatives: search for anti-inflammatory activity.A series of 2-hydroxy-2-indolyl-1,3-indandiones, diversely substituted on the heterocycle were synthetized in order to study their anti-inflammatory activity.Catalytic hydrogenation gave 2,3-dihydroxy-1 indanones 6 and NaBH4 reduction of 3i led to the corresponding indanetriol 7i.Base-catalyzed isomerization of hydroxy-β-diketones 3 furnished 3-indololylcarbonyl phthalides 9.Only compound 3d exhibited a significant inhibition of mouse paw edema.Experimentation in the rat paw edema test confirmed the anti-inflammatory effect of 3d, but it was associated with an anti-coagulant activity. ω-Amino-alkylation of the indole nitrogen of 3d led to loss of anti-inflammatory activity.Introduction of a double bond between the indandione and indole nuclei, leading to 2-(indol-3-ylmethylene)-1,3 indandiones 12, proved ineffective in raising this activity. 2-hydroxy-2-indolyl-1,3-indandiones/ 2,3-dihydroxyindanones/ 1,2,3-indantriols/ 3-indolylcarbonyl-phthalides/ 2-(indol-3-ylmethylene)-1,3-indandiones/ anti-inflammatory activity/ anti-coagulant activity
