Unlike the low solubility of uric acid formed by catabolism of purines, the end products of pyrimidine catabolism (carbon dioxide, ammonia, β-alanine, and γ-aminoisobutyrate) are highly water soluble. A ZnCl 2-catalyzed three-component coupling reaction allows the synthesis of various 4,5-disubstituted pyrimidine derivatives in a single step from functionalized enamines, triethyl orthoformate, and ammonium acetate. Using in vitro and in vivo metabolic profiling of TNBC cells, we show that an increase in the abundance of pyrimidine nucleotides occurs in response to chemotherapy exposure.
