ARN-75039 (ARN75039) is a potent, small molecule fusion inhibitor of arenavirus, inhibits pseudotyped entry of pGTOV and pCHAPV with EC50 of 0.13 and 4.3 nM, respectively.ARN-75039 demonstrated sub-nanomolar EC50 activity against pTCRV that further translated to native wild-and NWAs, including LASV, JUNV and MACV, in pseudotyped virus assays and against native replicative LASV and JUNV.ARN-75039 also potently inhibits mutant T434I pTCRV variant with EC50 of 29 nM.ARN-75039 dramatically improved survival outcome and potently inhibited TCRV replication in serum and various tissues at doses of 10 and 35 mg/kg, provided highly significant post-exposure protection in mice against TCRV infection.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C.
