Table 5 summarizes these inhibitors and their biological effects. In terms of the cGAS–STING pathway agonists, studies have concentrated on the STING agonists due to their anti-tumor effect. These agonists include CDN, non-CDN, and indirect agonists [200]. Table 6 displays the typical STING agonists and their preclinical effects. Here, NT5C is linked to neoplasm.
