Retro-2
![{PARAM:[Name]}()](https://resource.bocsci.com/structure/1201652-50-7.gif)
| Category | Filovirus |
| CAS | 1201652-50-7 |
| Description | Retro-2 is a selective inhibitor of retrograde protein trafficking at the endosome-trans-Golgi network interface. Retro-2 is an ebolavirus (EBOV) infection inhibitor with an EC50 of 12.2 µM in HeLa cells. Retro-2 induces cell Autophagy. |

| In Vitro | Retro-2 (1 μM; 1-4 hours) induces Autophagy in GFP-LC3-expressing HeLa cells and promoted the dramatic cytoplasmic accumulation of large autophagosomes. Retro-2 (1 μM; 0.5-4 hours) treatment hows an increase over time of the abundance of LC3-II protein in cells. Retro-2 impairs the trafficking between autophagosomes and lysosomes. Retro-2 abolishes autolysosomes formation. Retro-2 (20 μM; pretreatment for 30 min) inhibits HeLa cell intoxication by ricin, Shiga-like toxins 1 (Stx1) and 2 (Stx2). Retro-2 blocked invasion of cells by the intracellular parasite Leishmania, as well as replication of non-enveloped viruses, including polyoma-, papilloma-, and adeno-associated viruses. |
| In Vivo | Retro-2 (2-200 mg/kg; i.p; daily; for 21 days) treatment clearly protects from lethal nasal exposure to ricin in mice. 200 mg/kg of Retro-2 fully protects mice against ricin challeng |
