rTRD01
Based on 1 Customer Validation
rTRD01 is an orally active, specific TDP-43 binder that targets the RRM1 and RRM2 domains of TDP-43. rTRD01 partially disrupts the interaction between TDP-43 and c9orf72 repeat RNA, but does not affect the binding of TDP-43 to canonical binding sequences. rTRD01 exhibits significant neuroprotective effects in zebrafish models, improves motor function and protects against paraquat (a widely used herbicide)-induced neurodegeneration, with no teratogenicity at high concentrations. rTRD01 is not a general antioxidant and cannot counteract Rotenone (HY-B1756)-induced neuronal death. rTRD01 can be used to study amyotrophic lateral sclerosis and other TDP-43 proteinopathies.

生物活性
Kd: 89 uM (TDP-43102–269)[1]
rTRD01 (500 μM) binds specifically to recombinantly purified human TDP-43(102-269)-His protein[1].
rTRD01 (0.03 μM-1 mM) binds to recombinantly purified human TDP-43(102-269)-His protein with an apparent dissociation constant of 89.4 μM, as measured by MST[1].
rTRD01 (0.01 mM-1 mM; 30 min pre-incubation with TDP-43 proteins, 90 min incubation with RNA) selectively inhibits the interaction of recombinantly purified human TDP-43 proteins with disease-linked (GGGGCC)4 c9orf72 RNA, with an IC50 of ~150 μM for TDP-43(102-269)-His, while sparing interactions with canonical (UG)6 RNA[1].
rTRD01 binds to the RNA recognition motifs of human TDP-43 and partially disrupts its interaction with disease-associated (GGGGCC)4 RNA[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
rTRD01 (10-75 μM; incubated in E3 medium; starting at 12 hpf) protects against paraquat-induced neurodegeneration in zebrafish embryos by a non-general antioxidant mechanism, as evidenced by rescue of spinal curvature and brain morphology metrics with no effect on rotenone-induced neuronal death[2].

Animal Model:D42 GAL4 driver line (crossed with w1118 genetic background control, or lines expressing human TDP-43G298S/TDP-43WT; motor neuron expression of human G298S mutant TDP-43 via GAL4-UAS system)[1]
-
Dosage:20 μM
-
Administration:feeding; single exposure
-
Result:Reduced larval turning time in TDP-43G298S-expressing larvae from 19.3 s to 12.3 s.
Showed no significant improvement in larval turning time in TDP-43WT-expressing larvae.
-
Animal Model:Tübingen driver line (TDL6)[2]
-
Dosage:10 μM, 25 μM, 50 μM, 75 μM
-
Administration:incubated in E3 medium; starting at 12 hpf; media refreshed every 24 hours (co-treatment); washed at 18 hpf (sequential treatment)
-
Result:Reduced spine deformity prevalence from ~70% with paraquat alone to ~10% with 50 μM rTRD01 co-treatment or sequential treatment.
Eliminated statistically significant reductions in brain cross-sectional area, mean fluorescence, and fluorescence density caused by paraquat alone with 50 μM rTRD01 co-treatment.
Showed no protective effect against rotenone-induced gray brain phenotype at doses of 10, 25, 50, or 75 μM.
Was well-tolerated up to 75 μM, with no discernable morphological defects and >90% survival through 5 dpf at all tested doses.
