Application

(S)-2-Aminobutane-1,4-dithiol hydrochloride (DTBA), also known as dithiobutylamine, is a biological reducing reagent with enhanced properties over other commonly used reagents. DTBA was shown to reduce small molecule disulfides 3-5x faster than DTT and was able to reduce (activate) the cysteine dependent protease papain 14x faster than DTT. In addition, due to the presence of the primary amine group, removal of DTBA from mixtures after use is simplified and can be achieved using cation exchange resin.

Ovarian cancer is considered to be the most fatal reproductive cancers. Melphalan is used to treat ovarian cancer as an intraperitoneal chemotherapy agent. However, elucidating its pharmacokinetic behavior and preparing it for administration are challenging since it undergoes spontaneous hydrolysis.
