Evrys Bio LLC


Biotechnology company developing host-directed, broad‑spectrum small‑molecule antivirals that modulate human sirtuin enzymes (especially SIRT2) to enhance intrinsic cellular antiviral defenses. Activities focus on preclinical discovery, in‑vitro and in‑vivo efficacy testing across multiple virus families, intellectual property licensing, and government‑funded program development for clinical translation and biodefense applications.
