RSV-IN-14
RSV-IN-14 is an orally active pre-fusion F protein inhibitor of respiratory syncytial virus (RSV), with a Kd of 5.0 μM, and exhibits lung-targeted distribution properties. RSV-IN-14 binds to the central cavity of the trimeric pre-fusion F protein, locks it in the pre-fusion state, and inhibits the conformational changes required for membrane fusion to block viral entry. RSV-IN-14 suppresses respiratory syncytial virus-induced syncytium formation. RSV-IN-14 can be used in studies on respiratory syncytial virus infection.

Biological Activity
Description
IC50 & Target
[1]|
RSV pre-fusion F protein 5.0 μM (Kd) |
In Vitro
RSV-IN-14 (50 μM) exerts potent broad-spectrum inhibitory activity against diverse clinically isolated RSV subtype strains in in vitro[1].
RSV-IN-14 forms a stable protein-ligand complex by directly binding to the prefusion conformational epitope of the RSV F protein[1].
RSV-IN-14 (0.1-1.0 nM) effectively suppresses RSV infection, viral protein expression, and syncytium formation while restoring normal epithelial structure in aged human nasal organoids[1].

Parmacokinetics
In Vivo
RSV-IN-14 (12.5-50 mg/kg; p.o.; twice daily; 3 consecutive days) effectively inhibits pulmonary RSV replication and ameliorates RSV-induced severe lung injury in 65-week-old aged C57BL/6 mice, with the 50 mg/kg dose achieving 82% reduction in both viral titer and RSV-F gene copies[1].

-
Animal Model:BALB/c mice (4-week-old female)[1]
-
Dosage:100 mg/kg
-
Administration:p.o.; twice daily; 3 consecutive days
-
Result:Attenuated RSV-induced progressive body weight loss in infected mice.
Reduced the elevated lung index by 12.9% relative to the RSV-infected control group at 3 days post-infection.
Reduced pulmonary RSV-F protein mRNA expression by 92.98% at 3 days post-infection.
-
Animal Model:C57BL/6 mice (4-week-old female)[1]
-
Dosage:12.5 mg/kg; 50 mg/kg; 100 mg/kg
-
Administration:p.o.; twice daily; 3 consecutive days
-
Result:Produced greater than 90% reduction in RSV-F gene copy levels in lung tissue across all tested doses.
Resulted in only transient initial body weight decrease at 1 day post-infection followed by recovery over subsequent 2 days, in contrast to the 18.8% progressive body weight loss observed in untreated RSV-infected mice by 3 days post-infection.
Reduced lung index values, attenuated inflammatory cell infiltration and virus-induced lung tissue damage, and markedly suppressed pulmonary mRNA expression of the pro-inflammatory cytokines TNF-α, IL-1β, and IL-6 across all dose groups.
-
Animal Model:C57BL/6 mice (65-week-old male)[1]
-
Dosage:12.5 mg/kg; 50 mg/kg
-
Administration:p.o.; twice daily; 3 consecutive days
-
Result:Alleviated the downward trend of body weight in RSV-infected aged mice, though body weight recovery was slower than that observed in juvenile mice.
Produced an 82% reduction in lung viral titer and an 82% reduction in RSV-F gene copies at the 50 mg/kg dose level.
Reduced the elevated lung index values by 18-32% relative to RSV-infected mice.
Alleviated the severe RSV-induced lung pathology including lymphocytic/granulocytic infiltration, alveolar septal thickening, necrotic cellular debris, alveolar/bronchial hemorrhage, perivascular lymphocytic cuffing and vascular congestion, with the 50 mg/kg dose demonstrating greater efficacy than 12.5 mg/kg.
