Viral Infection
FGI-103 (20 µM; overnight pretreatment-48 h post-infection) inhibits ZEBOV-GFP infection in Vero E6 cells in a dose-dependent manner[1].
FGI-103 (overnight pretreatment-incubation for 48 h) inhibits the replication of wild-type ZEBOV, SEBOV, MARV-Ravn, and MARV-Ci67 in the Vero E6 virus yield assay, with EC50 values of 100 nM, 420 nM, 2.5 μM, and 2.5 μM, respectively[1].

Viral Infection
FGI-103 (10 mg/kg; i.p.; administered 1 h before infection and on days 2 and 5 after infection; observed for 14 days) completely protects C57BL/6 mice against lethal mouse-adapted ZEBOV challenge[1].
FGI-103 (5-10 mg/kg; i.p.; administered once on day 1 post-infection; 14-day observation) exhibits activity in the C57BL/6 mouse model infected with the mouse-adapted ZEBOV strain, providing complete protection (100% survival in the 10 mg/kg group) or partial protection (60% survival in the 5 mg/kg group) of mice from lethal infection when administered therapeutically[1].
FGI-103 (5-10 mg/kg; i.p.; administered once on day 1 post-infection; 14-day observation) exhibits activity in the BALB/c mouse model infected with the mouse-adapted strain MARV-Ravn, providing complete protection (100% survival in the 10 mg/kg group) or partial protection (40% survival in the 5 mg/kg group) of mice against lethal Marburg virus challenge when administered therapeutically[1].

Cytokines & Chemokines
FGI-103 (10 mg/kg; i.p.; administered once on day 1 post-infection; days 2-8) delays viral appearance, reduces viral load in the kidney/liver/spleen and serum, inhibits pro-inflammatory cytokine secretion, lowers liver enzyme levels, and attenuates histopathological damage in the liver and spleen in the ZEBOV-infected C57BL/6 mouse model[1].

Animal Model:C57BL/6 mice (8-10 weeks old) were established with a lethal infection
model via intraperitoneal (i.p.) injection of 1,000 PFU of mouse-adapted Zaire ebolavirus
(ZEBOV)[1] -
Dosage:10 mg/kg
-
Administration:i.p.; day 0 (1 h before infection), day 2, and day 5 postinfection; 14 days
-
Result:Vehicle-treated mice had 90% mortality.
Completely protected mice against lethal EBOV challenge (100% survival).
Transient overt signs of EBOV infection occurred in 5 of 10 mice beginning on day 8; all mice were healthy beginning 10 days after infection.

Animal Model:C57BL/6 mice (8-10 weeks old) were established with a lethal infection
model via intraperitoneal (i.p.) injection of 1,000 PFU of mouse-adapted Zaire ebolavirus
(ZEBOV); BALB/c mice (8-12 weeks old) were established with a lethal infection model
via intraperitoneal injection of 1,000 PFU of mouse-adapted Marburg virus (MARV-Ravn)[1] -
Dosage:5 mg/kg;10 mg/kg
-
Administration:i.p.; once at day 1 postinfection; 14 days
-
Result:Completely protected mice infected with EBOV or MARV (100% survival), while
the 5 mg/kg dose provided 60% (EBOV) and 40% (MARV) protection rates, respectively.

Animal Model:C57BL/6 mice (8-10 weeks old) were established with a lethal infection
model via intraperitoneal (i.p.) injection of 1,000 PFU of mouse-adapted Zaire ebolavirus
(ZEBOV)[1] -
Dosage:10 mg/kg
-
Administration:i.p.; once at day 1 postinfection; 2, 4, 6, 8 days
-
Result:Delayed the time at which the virus was detected in kidneys, liver, spleen, and serum.
Significantly reduced the viral load in tissues and serum, with titer levels often 1 to 2 logs (10- to 100-fold) lower than those in the control group.
Suppressed the cytokine storm, significantly lowering the levels of MCP-1 and IL-6 in the serum, which never reached the peak levels observed in the control group.
Protected liver function, significantly reducing the surge in concentrations of liver damage marker enzymes (ALT, AST, ALP) at day 6 postinfection.
Alleviated histopathological damage, mitigating hepatocellular necrosis in the liver and lymphocytolysis in the spleen, and restricted the widespread dissemination of viral antigens by day 6.
