Synthesis and Evaluation of Novel N-Aryl-2-Chloroacetamides

Check if the same lab product or an alternative is used in the 5 most similar protocols
Chemicals: chemicals of this work (4-(N,N-dimethylaminobenzaldhyde, Cyanothioacetamide, Piperidine, Methyl iodide, Ethyl Chloroacetate, 2-Chloroacetamide, Chloroacetonitrile or N-aryl-2-Chloroacetamides, Ethanol, Sodium acetate.3H2O, Sodium carbonate) were purchased from Sigma Aldrich Co.
Instrumentations: Melting points were determined on a Gallan-Kamp apparatus and are uncorrected. The purity of the compounds was ensured by TLC and the spectroscopic analysis.
IR spectra were recorded on a Shimadzu 470 IR-spectrophotometer (KBr; νmax in cm−1). The 1H and 13C NMR spectra were recorded on Varian A5 500 MHz spectrometer using DMSO-d6 as a solvent and tetramethylsilane (TMS) as an internal reference. Coupling constants (J values) are given in Hertz (Hz). Elemental analyses were performed on a Perkin Elmer 2400 LS Series CHN/O analyzer.
Cell lines: The in vitro human breast cancerous cell line (MCF7), lung cancerous  cell lines (A549) and normal cell lines were purchased from Serum and Vaccine formulation in Cairo-Egypt.
Molecular docking: Molecular docking studies were performed in (I Mole Lab for bioinformatics, Cairo, Egypt).
Softwares: The biological data was analyzed and plot by Graphpad prism, Cell qust, ANOVA, Origin Lab, AutoDock Vina 1.1.2, Mestrenova and Excel software.

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.
