Proton NMR spectra and Carbon NMR spectra were recorded with Bruker Adanve - II 400 NMR spectrophotometer using DMSO-d6 as a solvent, at Sophisticated Analytical Instrumentation Facility, Punjab University, Chandigarh. The surface analysis was performed using scanning electron microscop...
In 1H NMR data, chemical shifts are quoted in ppm and referenced to the residual solvent signals (DMSO-d6, δ = 2.49), and signal splitting patterns are described as singlet (s), doublet (d), triplet (t), quartet (q), multiplet (m), and broad (br). Coupling constants (JH-H) ...
In addition, the reaction was carried out under solventless conditions and it was found that the reaction was carried out in very shorter reaction time and in higher yield under solventless condition (Table 6, entry 9). Therefore, solvent free conditions and using water as a solvent are ...
The binding pocket is not freely accessible to the solvent but our structural analysis suggests the opening of an exit channel between 100 μs and 1 ms (Fig.3B). Reorganization of the βT7 loop, particularly through a rotation of the βLeu246 side chain, results into an 8-Å-long...

1H–, 13C-NMR Spectra: Varian 200, Bruker 300 and 50, 75 MHz spectrometer, respectively; in CDCl3 or (D6) DMSO; δ in ppm relative to TMS as internal standard, J in Hz. Mass spectra: VG Autospec; in m/z. Typical procedure Indoles (1 mmol) and formaldehyde (1 ml, 37% aqueous...
The reaction residue was purified on a silica gel column chromatography using a mixed solvent (CHCl3: CH3CN ¼ 8.5: 1.5 v/v) as the eluent, and then the main band was collected. After removal of the solvent, a black powder was obtained. The black powder was then added to CF3COOH, ...
