DL-alanine is employed both as a reducing and a capping agent, used with silver nitrate aqueous solutions for the production of nanoparticles. DL-alanine can be used for the research of transition metals chelation, such as Cu(II), Zn(II), Cd(11). DL-alanine, a sweetener, is classed together with glycine and sodium saccharin. DL-alanine plays a key role in the glucose-alanine cycle between tissues and liver .

rac-Vofopitant-d3

rac-Vofopitant-d₃ (rac-GR 205171-d₃) is a racemic form of deuterated Vofopitant (HY-12142). Vofopitant (GR 205171A) is a blood-brain barrier-permeable NK1 receptor inhibitor with a pKi of 9.02 in mice. Vofopitant blocks vomiting-related responses and inhibits pseudoptyalism. Vofopitant exerts anxiolytic effects, regulates 5-HT receptor function and increases central 5-HT release. Vofopitant improves hyperarousal symptoms of post-traumatic stress disorder. Vofopitant can be used in research related to depression, anxiety, vomiting and postoperative nausea and vomiting .
