Several new pyridazino[1',6':1,2]pyrido[3,4-b]indol-5-inium derivatives were synthesised from beta-carboline derivatives and their cytotoxic activity and effect on the cell cycle were evaluated against L1210 cancer cells.
Synthesis of bis(indol-3-yl)methanes catalyzed by silicotungstic acid (SiO212WO324H2O) was carried out in 50-97% yield within 15-120 min in EtOH at r. t. under ultrasound irradiation.
Chemical reactivity descriptors of indol-4-ones obtained via density functional theory (DFT) and hard-soft acid-base (HSAB) principle were calculated to prove their contribution in antifungal activity [...].
Headspace solid-phase microextraction (HS-SPME) and ultrasonic solvent extraction (USE), followed by GC-MS/FID, were applied for monitoring the nectar (NE)/honey-sac (HoS)/honey (HO) pathways of the headspace, volatiles, and semi-volatiles. The major NE (4 varieties of Citrus unshiu) headspace compounds were linalool, α-terpineol, 1H-indole, methyl anthranilate, and phenylacetonitrile. Correspo...
A new series of novel triazolothiadiazepinylindole analogues were synthesized with an aim to examine possible antioxidant and antimicrobial activities. The titled compounds (3a-z) were obtained in good yield by reacting 5-(5-substituted-3-phenyl-1H-indol-2-yl)-4-amino-4H-1,2,4-triazole-3-thiols 1a-c with 3-(2,5-disubstituted-1H-indol-3-yl)-1(4-substituted phenyl)prop-2-en-1-ones 2a-i. All the n...
In the title compound, C(11)H(12)N(2)O(2)·C(7)H(5)NO(4)·C(2)H(6)O, the (2S*)-2-amino-3-(1H-indol-3-yl)propionic acid is present in the zwitterionic form. In the crystal structure, 2-amino-3-(1H-indol-3-yl)propionic acid mol-ecules and pyridine-2,4-dicarb-oxylic acid mol-ecules are linked through strong inter-molecular O-H⋯O and N-H⋯O hydrogen bonds, forming layers parallel to (100). The layers ...
Efficient one-pot synthesis of indol-3-yl-glycines via uncatalyzed Friedel-Crafts reaction in water.
The three component reaction of primary aliphatic amines, glyoxalic acid and indole or N-methylindole in water at ambient temperature affords indol-3-yl or N-methylindol-3-yl-glycine in almost quantitative yields.
