Cell experiment:

The HIV-1 strains A012 and A018 are used in the assay. Inhibition of p24 antigen is measured. Briefly, PHA-stimulated peripheral blood mononuclear (PBMCs) are incubated with either HIV-1 strain for 1 h at 37°C at 200-fold the 50% tissue culture infectious dose (TCID50) of the virus stock per 2 × 105 PBMC cells. The TCID50 is defined as the amount of virus stock at which 50% of the inoculated wells are positive. Cells are then grown in microtiter plates with different drug concentrations at 2 × 105 cells per well. On day 4, cells are resuspended and split 1:3 with fresh media and 3-Deazaadenosine. Supernatant p24 antigen is determined on day 7 by ELISA[1].

3-Deazaadenosine is an inhibitor of S-Adenosylhomocysteine (SAH) hydrolase.

S-Adenosylhomocysteine (SAH) hydrolase can catalyze the reversible hydrolysis of SAH to adenosine and homocysteine. The inhibition of SAH hydrolase result in the intracellular accumulation of SAH, elevating the ratio of SAH to S-adenosylmethionine (SAM) and also inhibiting SAM-dependent methyltransferases.

In vitro: 3-Deazaadenosine showed inhibitory values against the EBO-Z viruses, EBO, and Marburg virus in various cell lines of primate (SW13, Vero 76, FRhL, LLC-MK2, MRC-5, Vero E6) and mouse (BALB/3T3 clone A31) origin. 3-Deazaadenosine at 2 μg/mL could reduce viral replication by 3 logs in a dose-dependent manner. However, there was no further inhibition even with a 100-fold increase in concentration [1].

In vivo: In vehicle control group, adult BALB/c mice lethally infected with mouse-adapted Ebola virus die 5–7 days after infection. In contrast, 3-deazaadenosine treatment initiated on day 0 or 1 led to a dose-dependent protection, with mortality completely prevented at doses around 0.7 mg/kg every 8 h. Moreover, there was significant protection when 3-deazaadenosine treatment was begun on day 2, at which time, the spleen had an average titer of 2 × 106 pfu/g and the liver had 3 × 105pfu/g virus. Treatment with 3-aeazaadenosine at 2.2 mg/kg initiated on day 3 resulted in 40% survival [1].

Clinical trial: Up to now, 3-deazaadenosine is still in the preclinical development stage.
