Tegoprubart
Based on 1 Customer Validation
Tegoprubart (AT-1501) is a CD40 ligand inhibitor (EC50=100 ng/mL) and immunosuppressant that selectively inhibits the CD40 ligand, a co-stimulatory molecule involved in T cell activation. Tegoprubart suppresses immune rejection, prevents rejection in animal transplantation models, and reduces cell-mediated and antibody-mediated immune responses to create a more immunotolerant environment. Tegoprubart preserves renal function when combined with Mycophenolate (HY-B0421) and Corticosteroids, and maintains graft function in preclinical studies. Tegoprubart is applicable to research related to kidney transplantation and kidney transplant rejection.

CD40L |
The immune complex formed by Tegoprubart (600 nM; in vitro platelet activation assay) and soluble CD40L fails to induce PAC-1 expression on the surface of platelets from healthy individuals, does not trigger platelet aggregation, and exerts no platelet-activating effect; in contrast, the immune complex formed by Hu5C8 (HY-P99315) and soluble CD40L significantly induces platelet aggregation[1].
Tegoprubart (2 μg/mL; 1 h; CD40L binding assay) exhibits binding affinity to recombinant human CD40L comparable to that of Hu5C8, with both antibodies having an EC50 value of 100 ng/mL[1].

-
Cell Line:No specific cell line (in vitro protein binding system with recombinant human CD40L)
-
Concentration:2 μg/mL
-
Incubation Time:Overnight coating at 4°C, 1 hour of incubation
-
Result:Exhibited a binding affinity to recombinant human CD40L that was comparable to that of Hu5C8, with an EC50 value of 100 ng/mL for both antibodies.
Abatacept (HY-108829) was used as a negative control and showed no binding to CD40L.
In the cynomolgus monkey intrahepatic islet allotransplantation model, tegoprubart (25 mg/kg; intravenous injection; once on days -2, -1, 0, 1, 3, 7, 10, 18, 23, and 28 post-operation, then once every 14 days thereafter; for 182 days), when combined with thymoglobulin (5 mg/kg, intravenous injection on days -2, -1, 0, 1, and 2 post-operation), rapamycin, and anti-TNF-α, maintains islet graft function, enables insulin independence in some animals, and causes no severe cytomegalovirus (CMV) reactivation[1].

Animal Model:Cynomolgus Monkey Intrahepatic Islet Allotransplantation Model (MHC-disparate intrahepatic islet allotransplantation model, induced with 100 mg/kg IV streptozotocin to establish diabetes)[1]
-
Dosage:25 mg/kg,
-
Administration:Intravenous injection; administered on POD#−1, 0, 3, 10, 18, 23, 28, then biweekly for 182 days
-
Result:One recipient remained insulin-free until POD#182 with improved %A1C and fasting C-peptide > 1.0 ng/mL, accompanied by increased CD4+ regulatory T cell (Treg) frequencies; the other recipient rejected the first graft within 2 weeks but achieved partial graft function after a second transplant on POD#98, maintaining C-peptide > 1.0 ng/mL until POD#182; no thromboembolic events were observed throughout the study.

Immobilized CD40L/CD154/TRAP Protein, Human (His, HY-P72907) can bind Tegoprubart. The EC50 for this effect is 4.211 ng/mL. -
Flow cytometric analysis of 1X106 500 ng/mL anti-CD3 stimulated Jurkat cells(24h) with Tegoprubart (HY-P990083, red). Cells were fixed with 4% paraformaldehyde. Then stained with the primary antibody at 1/200 dilution for an hour at 4℃. Alexa Fluor 488-conjugated AffiniPure Goat Anti-Human IgG H&L (HY-P83776) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Human IgG1 kappa Isotype Control (HY-P99001, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black). -
Loaded Tegoprubart on ProA biosensor, can bind CD40L/CD154/TRAP Protein, Human (HY-P7144) with an affinity constant of 4.923E-10 M as determined in BLI assay.
