Ro 13-3978
Ro 13-3978 is an orally active antischistosomal agent. Ro 13-3978 exhibits excellent in vivo antischistosomal activity against juvenile and adult Schistosoma mansoni infections. Ro 13-3978 shows no in vivo activity against E. caproni and F. hepatica. Ro 13-3978 blocks dihydrotestosterone-induced proliferation of androgen-dependent cells. Ro 13-3978 can be used in research related to schistosomiasis.

Biological Activity
|
Schistosome |
Ro 13-3978 (100 μg/mL; 72 h) moderately reduces the motility of newly transformed S. mansoni schistosomula in vitro without causing tegument damage[1].
Ro 13-3978 (0.12-90 μM; 70 h) shows no cytotoxicity against rat skeletal myoblast L6 cells at concentrations up to 90 μM after 70 h of incubation, with an IC50 greater than 90 μM[1].
Ro 13-3978 (25-100 μg/mL; 72 h) causes mild tegumentary changes in adult S. mansoni worms in vitro, including wrinkling in males and sloughing in a subset of females[1].

Ro 13-3978 (100 mg/kg; p.o.; single dose) shows stage-specific antischistosomal activity in NMRI mice, with high efficacy (64.3-94.6% total WBR) against S. mansoni from day 22 post-infection onwards, no activity against 7-14 day-old worms, and moderate efficacy when administered pre-infection[1].

Dosage:12.5-100 mg/kg (adult infections); 50-200 mg/kg (juvenile infections)
-
Administration:p.o.; single dose

Result:Reduced total adult S.
mansoni worm burden by 37.1%, 82.6%, 78.2%, and 94.6% at 12.5 mg/kg, 25 mg/kg, 50 mg/kg, and 100 mg/kg respectively.
Reduced female adult S.
mansoni worm burden by 33.8%, 84.5%, 57.3%, and 88.0% at 12.5 mg/kg, 25 mg/kg, 50 mg/kg, and 100 mg/kg respectively.
Calculated an ED50 of 14.6 mg/kg for 49 day-old S. mansoni infections.
Reduced total juvenile S.
mansoni worm burden by 0%, 63.8%, and 88.1% at 50 mg/kg, 100 mg/kg, and 200 mg/kg respectively.
Reduced female juvenile S.
mansoni worm burden by 0%, 57.3%, and 85.4% at 50 mg/kg, 100 mg/kg, and 200 mg/kg respectively.
Calculated an ED50 of 138.9 mg/kg for 22 day-old S. mansoni infections.
