ITE is a potent endogenous agonist of aryl hydrocarbon receptor (AhR), which directly binding to AHR with a Ki of 3 nM. ITE potently inhibits human pulmonary artery endothelial (HPAECs) growth at 10 and 20 µM. ITE (20 µM) elevates CYP1A1 and CYP1B1 mRNA levels and decreases the levels of AhR protein in HPAECs.
In vivo, ITE (200 μg, i.p.) significantly suppresses the development of experimental autoimmune uveitis (EAU) in mice. ITE reduces the proportions of cells expressing IFN-γ, IL-17, or IL-10 in mice. ITE also suppresses the secretion of inflammatory cytokines by LN cells in mice.

Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.

Belatacept
Belatacept (BMS 224818) is a fusion protein composed of the Fc fragment of a human IgG1 immunoglobulin linked to the extracellular domain of CTLA-4, which is a molecule crucial in the regulation of T cell costimulation, selectively blocking the process of T-cell activation. Belatacept binds to CD 80/86 ligands and thereby inhibits the CD-28-mediated T-cell costimulation. Belatacept can be used in the research of Immunosuppression in organ transplants. |
MK-4830
MK-4830 is a novel, first-in-class human IgG4 monoclonal antibody targeting the myeloid-specific ILT4 (immunoglobulin-like transcript 4) receptor. MK-4830 catalyzes reprogramming of tumour-associated macrophages, relieving myelosuppression and enhancing T cell function. |
