Pharmacological inhibitors, including RU.521 (cGAS antagonist), C-176/H-151 (STING palmitoylation blockers), and the TBK1 inhibitor amlexanox, effectively lower pro-inflammatory cytokines (IL-1β, IL-6, TNF-α) and improve left ventricular ejection fraction in diabetic cardiomyopathy and ischemia–reperfusion injury models. This evidence concerns the gene IL6 and diabetic cardiomyopathy.
