With the exception of very simple aliphatic acids such as valproic acid (VPA), these molecules conform to a common pharmacophore (Figure 1C), comprising a linker mimicking a lysine side chain, and a cap structure of variable size that makes additional interactions around the rim of the enzyme active site

Red or purple chromaturia is a side effect of hydroxocobalamin, typically resolving over several weeks.2 Additional causes of red urine include blood (e.g., traumatic catheterization, malignancy, infection), dietary ingestion (e.g., beets), and medications (e.g., rifampin, phenothiazines).3 Although benign and not warranting further evaluation by itself, hydroxocobalamin-induced discolouration of body fluids may interfere with colorimetric sensors
