All the reagents for the present study were purchased from commercial suppliers of Sigma-Aldrich, Spectrochem India and Himedia. Melting points were determined in an open capillary tube and were uncorrected. Thin layer chromatography (Merck silica gel 60 F254 coated aluminium plates) confirmed the purity of the products. Synthesised compounds were characterized by 1H-NMR, 13C-NMR, FT-IR, LC-MS and elemental analysis. FT-IR spectrum was recorded on Shimadzu-FTIR Infrared spectrometer (γmax in cm−1). 1H-NMR (400 MHz) and 13C-NMR spectrum, was recorded on a Bruker Advance II 400 spectrometer, with5mm PABBO BB-1H Tubes, using DMSO/CDCl3 as a solvent, using TMS as internal standard (Chemical shift in δ ppm). Elemental analysis was carried out by using VARIOEL-III (Elemental analyze system GmBH). LC-MS was obtained by using Agilent 1200 series LC and MicromasszQ spectrometer. DNA binding studies were carried out using ELICO SL 159 UV-VIS Spectrophotometer.
Ftir infrared spectrometer

All the essential chemicals used for this synthesis were procured from Merck, S.D. Fine, Sigma-Aldrich Company. The reagents and solvents were analytical grade and used without further purification. Melting points of newly synthesized compounds was determined via the open capillary technique. and was uncorrected. The complection of every steps was identified by TLC analyses on silica plates and spots were visualised via UV light, exposure to iodine vapours. Hexane:Ethyl acetate (3:1) were the adopted solvent system. FTIR spectra were recorded on Shimadzu FTIR infrared spectrometer in KBr pellets also wavenumbers are specified in cm−1. 1H NMR and 13C NMR spectra were recorded on Bruker Avance III, 400 MHz and 100 MHz spectrometers, in the CDCl3 solvent system and chemical shift values were expressed in parts per million (ppm) downfield from TMS, an internal standard. Mass spectra recorded on Water, synapt G2 high detection mass spectrometry and are uncorrected. Elemental analysis was carried out using CHNS Elementar Vario EL III. Compounds were prepared according to reported procedures.

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.
