Synthesis and biological evaluation of 3-substituted-indolin-2-one derivatives containing chloropyrrole moieties.
Eighteen novel 3-substituted-indolin-2-ones containing chloropyrroles were synthesized and their biological activities were evaluated. The presence of a chlorine atom on the pyrrole ring was crucial to reduce cardiotoxicity. The presence of a 2-(ethyl-amino)ethylcarbamoyl group as a substituent at the C-4' position of the pyrrole enhanced the antitumor activities notably. IC50 values as low as ...
متن کاملTetramethylguanidiniumtriflate catalyzed Henry reaction of isatins: An efficient synthesis of 3-hydroxy-3-(nitromethyl)indolin-2-one derivatives and their anti-diabetic activity
The ionic liquid, N,N,N,N-tetramethylguanidiniumtriflate (TMGTf) was found to be an efficient catalyst solvent for Henry reaction between nitromethane and isatin derivatives to provide 3-hydroxy-3-(nitromethyl)indolin-2-one under mild conditions. The ionic liquid amenable to successive recycling without appreciable decrease in activity. Synthesized compounds have been screened for their anti-di...

متن کاملSynthesis of 3- Benzylidene, 5-Substituted 3-Benzylidene, 3- Hetarylmethylene and 5-Substituted Hetarylmethylene Derivatives of In- dolin-2-ones
A wide variety of titled compounds, several of which have neuro-protecting properties has been prepared in yields ranging between 70 to 90%. The compounds were identified by 1 HNMR, 13 C NMR, 1D and 2D NOE analysis, and HRMS. An investigation of the effect of certain 5-substitutuents on the E to Z ratios in DMSO-d6 was carried out. The 5nitro and 5-acetyl substituents were not isomerized, where...
متن کامل3-(Phenylimino)indolin-2-one
The imino C=N double bond in the title compound, C(14)H(10)N(2)O, exists in an E conformation, with the phenyl ring being twisted by 80.7 (1)° in one independent mol-ecule and by 81.4 (1)° in the other with respect to the plane of the indoline fused-ring system. The two independent mol-ecules are linked by N-H⋯O hydrogen bonds, forming a zigzag chain running along the a axis.
