ATIC-IN-1 (compound 14) acetate is an ATIC dimerization inhibitor with a K i value of 685 nM, essential for AICAR transformylase activity. It demonstrates anti-tumor effects by decreasing cell proliferation and division rates [1].

ATIC-IN-1 acetate at concentrations of 10 µM and 50 µM is a specific inhibitor that exhibits non-specific aggregation mechanisms whether in the presence or absence of bovine serum albumin (BSA) at 1 mg/mL and 10 mg/mL [1]. At higher concentrations ranging from 100-500 µM over 48 hours, ATIC-IN-1 acetate inhibits the proliferation of MCF-7 cells [1]. Additionally, at 250 µM over a period of 24 to 72 hours, it leads to a reduction in cell division rather than an increase in cell death [1].
