The UV–visible (UV–VIS) spectra were recorded with a Hitachi U-2001 (Hitachi High-Technologies Corporation, Tokyo, Japan) in diethyl ether (Et2O). The positive ion fast atom bombardment mass spectrometry (FAB MS) spectra were recorded using a JEOL JMS-HX 110A mass spectrometer (JEOL, Tokyo, Japan) with m-nitrobenzyl alcohol as a matrix. The positive ion electro spray ionization time of flight mass (ESI-TOF MS) spectra were recorded using a Waters Xevo G2S Q TOF mass spectrometer (Waters Corporation, Milford, CT, USA). The 1H-NMR (500 MHz) and 13C-NMR (500 MHz) spectra were measured with a Varian UNITY INOVA 500 spectrometer (Agilent Technologies, Santa Clara, CA, USA) in CDCl3. The chemical sifts are expressed in ppm relative to tetramethyl silane (TMS) (δ = 0) as an internal standard for 1H-NMR and CDCl3 (δ = 77) as an internal standard for 13C-NMR. J values are given in Hz. The CD spectra were recorded in EPA [Et2O–isopentane–ethanol (5:5:2)] at room temperature with a Jasco J-500C spectropolarimeter (Jasco corporation, Tokyo, Japan). Preparative high-performance liquid chromatography (HPLC) was performed on a Shimadzu LC-6AD with a Shimadzu SPD-6AV spectrophotometer (Shimadzu Corporation, Kyoto, Japan) set at 450 nm. The column used was a 250mmX10mm i.d. 10 μm Cosmosil 5SL-II and 5C18 II (Nacalai tesque, Kyoto, Japan).
Jms hx 110a mass spectrometer
Manufactured by JEOL
Sourced in Japan
The JMS-HX 110A is a high-resolution magnetic sector mass spectrometer manufactured by JEOL. It is designed to provide precise mass analysis of a wide range of chemical compounds. The instrument utilizes a magnetic field to separate ions based on their mass-to-charge ratio, allowing for the identification and quantification of various molecules.

The experiment
utilized reagents and solvents obtained from commercial sources and
used as received unless otherwise specified. Thin-layer chromatography
(TLC) was carried out on Sigma-Aldrich TLC plates, which were silica
gel and had a plate number of 1 over the glass support with a thickness
of 0.25 μm. Flash column chromatography was performed with Alfa
Aesar silica gel, which had a particle size of 230–400 mesh.
Melting points were measured by using a MELTEMP melting point apparatus
and were uncorrected. The 1H and 13C nuclear magnetic resonance (NMR)
spectra were measured by using a Varian UNITY INOVA instrument at
400 and 100 MHz, respectively. The chemical shifts (δ) were
reported in reference to solvent residual peaks (dimethyl sulfoxide
(DMSO)-d6, 1H, δ = 2.50 ppm, 13C,
δ = 39.52 ppm). The data were reported as follows: chemical
shift, multiplicity (s = singlet, d = doublet, t = triplet, q = quartet,
and m = multiplet), coupling constant J, and integration. High-resolution
mass spectra (HR-MS) were obtained on a JEOL JMS HX 110A mass spectrometer.
UV–vis spectra were recorded on a PerkinElmer Lambda 35 UV/vis
Spectrometer equipped with a PTP 1 + 1 Peltier Temperature Programmer
accessory at 37 °C. Fluorescence spectra were obtained with a
Horiba Jobin Yvon Fluoromax-4 spectrofluorometer using an excitation
wavelength of 360 nm and slit widths of 5 nm.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
