Poly(ADP-ribose) polymerase (PARP) enzymes use nicotinamide adenine dinucleotide (NAD+) to modify up to seven different amino acids with a single mono(ADP-ribose) unit (MARylation deposited by PARP monoenzymes) or branched poly(ADP-ribose) polymers (PARylation deposited by PARP polyenzymes). To enable the development of tool compounds for PARP monoenzymes and polyenzymes, we have developed active site probes for use in in vitro and cellular biophysical assays to characterize active site-directed inhibitors that compete for NAD+ binding. These assays are agnostic of the protein substrate for each PARP, overcoming a general lack of knowledge around the substrates for these enzymes. The in vitro assays use less enzyme than previously described activity assays, enabling discrimination of inhibitor potencies in the single-digit nanomolar range, and the cell-based assays can differentiate compounds with sub-nanomolar potencies and measure inhibitor residence time in live cells. Wigle et al. describe a versatile set of NAD+-competitive probes for PARP enzymes that are used to build high-throughput in vitro and cellular biophysical assays that enable inhibitor screening and determination of residence time.

The preparation method of 3 - (t-butoxycarbonylamino) propionic acid comprises the following steps: Step S1, reacting methylaminopropanol with Boc anhydride to generate 3 - (t-butoxycarbonylamino) propanol. Step S2: The 3 - (t-butoxycarbonyl) propanol is subjected to an oxidation reaction under the action of a catalyst to generate the 3 - (t-butoxycarbonylamino) propionic acid. To the preparation method disclosed by the embodiment of the invention, the steps are simple, and the reaction is easy to process. Can be suitable for a pot method, can effectively reduce the waste water that is difficult to handle. The method is more suitable for industrial production.
