Astin C (Asterin), a naturally occurring cyclic peptide that can be extracted from Aster tataricus, specifically blocks IRF3 recruitment at the STING signalosome inhibiting cGAS-STING signaling and innate inflammatory responses triggered by cytoplasmic dna, resulting in mice that are more susceptible to HSV-1 infection and significantly attenuating autoinflammatory responses.

Diversoside is a natural product from Aster subspicatus.

Astin A has antitumor activity.
