Reactants and reagents were used as received.
Commercial HU-331 was purchased from Abcam.
Compound homogeneity was monitored by ascending thin-layer chromatography, performed on Merck 0.2 mm aluminium-backed silica gel 60 F254 plates and visualised using ultraviolet irradiation (254 nm) or by using aqueous alkaline potassium permanganate. Flash column chromatography was performed using Merck silica gel 60 of particle size 33-70 mm. Evaporation refers to the removal of solvent under reduced pressure. Melting points were determined using an Optimet apparatus and are uncorrected. Infrared (IR) spectra were recorded on a Bruker alpha FT-IR spectrometer using neat samples.

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.
