HIV-1 inhibitor 5b is a novel anti-HIV-1 compound that inhibits HIV-1 JR-CSF with EC50 of 1 nM without significant cytotoxicity (CC50>20 uM), also shows potency against NRTI- and NNRTI-resistant HIV-1 (EC50=1-3 nM); shows a chemical backbone similar to the clinically used integrase (IN) strand transfer inhibitor (INSTI) elvitegravir, but has no detectable INSTI activity; various drug-resistant HIV-1 strains did not display cross resistance to HIV-1 inhibitor 5b; remains its anti-HIV-1 activity even after the viral integration stage, significantly suppresses p24 antigen production in HIV-1 latently infected cells exposed with TNF-alpha; demonstrates favorable pharmacokinetic profiles in mice.

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.
