The 4-nitro-1H-indole-carboxaldehyde (NICA) molecule was characterized experimentally using FT-IR, FT-Raman and UV-Vis spectra, and it was studied theoretically using DFT calculations. The optimized structure of the NICA molecule was determined by DFT calculations using B3LYP functional with cc-pVTZ
Spectroscopic investigations are performed for 5-Bromo-1H-indole-carboxaldehyde by using experimental (FT-IR, FT-Raman) and theoretical (DFT) calculations. Vibrational assignments of the fundamental modes were assigned on the basis of Potential energy distribution (PED) calculations. Electron
The present paper reports an easy preparation of imines of N-methyl-1H-indole-3-carboxaldehyde by its condensation with alkyl and aromatic amines in ethanol without using any catalyst or dehydrating agent. The compounds have been screened for their antibacterial, antifungal, crown gall tumor
Indole-3-carbinol (I3C), a natural component of Brassica vegetables, is a promising cancer preventive agent that can reduce the incidence of tumors in reproductive organs when administered in the diet. Here we report on the metabolic fate of radiolabeled I3C in MCF-7 cells. I3C was surprisingly
A series of bis(indolyl) hydrazide-hydrazones 5a-n were synthesized and evaluated for their cytotoxicity against selected human cancer cell lines. The reaction of indole-3-carboxaldehyde 2 with indole-3-carbohydrazide 4 in presence of catalytic amount of acetic acid afforded 5a-n in good yields.
The methanol extract of an assemblage of Halimeda stuposa and a Dictyota sp., yielded three natural products characteristic of Dictyota sp., and one of Halimeda sp. These included the xenicane diterpene 4-hydroxydictyolactone (1), and the diterpenes dictyol E (2), 8a,11-dihydroxypachydictyol A (3)
A series of eleven novel bisindole derivatives were synthesized and screened for anticancer and antiobesity potentials in in vitro mode. The reaction of 1-ethoxy carbonyl 4-pyperidone 1a with indole-3-carboxaldehyde 1b in presence of catalytic amount of piperidine gave 2 which was N-alkylated with
Based on the structural elements of bioactive indole-based compounds, a series of novel 1-substituted indole-3-carboxaldehyde thiosemicarbazones were synthesized as potential antimycobacterial and anticancer agents. The derivatives were prepared via a two-step methodology including
An effective synthesis of analogs of the indole phytoalexin cyclobrassinin with NR1R2 group instead of SCH3 was developed starting from indole-3-carboxaldehyde. The target compounds were prepared by spirocyclization of 1-Boc-thioureas with the formation of isolable spiroindoline intermediates,
Bioactivity-guided fractionation of the extract from a Fijian red alga Peyssonnelia sp. led to the isolation of two novel sterol glycosides 19-O-β-d-glucopyranosyl-19-hydroxy-cholest-4-en-3-one (1) and 19-O-β-d-N-acetyl-2-aminoglucopyranosyl-19-hydroxy-cholest-4-en-3-one (2), and two known alkaloids
C-glycosides are important class of molecules exhibit diverse biological activities and present as structural motif in many natural products. Two series of new pyrazoline and isoxazole bridged indole C-glycoside molecular hybrids (n = 36) were efficiently synthesized starting from diverse indole
Indole-3-carbinol (I3C) and 3,3'-diindolylmethane (DIM) are promising cancer chemopreventive agents in rodent models, but there is a paucity of data on their pharmacokinetics and tissue disposition. The disposition of I3C and its acid condensation products, DIM,
The present study involves diversity and biological activities of the endophytic fungal community from Distylium chinense, a rare waterlogging tolerant plant endemic to the Three Gorges Reservoir. This study has been conducted hypothesizing that the microbial communities in the TGR Flavonoids are naturally occurring compounds with versatile health-promoting effects against various diseases.To synthesize and evaluate biological activity of novel flavone derivatives against cancer.A new series of
