Biological Activity

TAPI blocks the spontaneous and PMA-induced release of TNF-alpha from transfected cells. TAPI-1, an inhibitor of ADAMs, reduced constitutive and muscarinic receptor-stimulated sAPP alpha release in HEK-293 cells stably expressing M3 muscarinic receptors. TAPI-1 with the EGFR inhibitor AG1478 exhibits deactivated AREG/EGFR/ERK signaling pathway and reduces pro-inflammatory cytokines release in pSS salivary gland-derived epithelial cells.

Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
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.

Lintuzumab

Lintuzumab is a humanized monoclonal antibody directed against CD33, which is expressed on the majority of myeloblasts in acute myeloid leukemia.

Evorpacept

Evorpacept (ALX148) is a high affinity CD47-blocking fusion protein with an inactive human immunoglobulin Fc region designed to enhance the activity of other anti-neoplastic therapies, with minimal additional toxicity.

Litifilimab

Litifilimab is a humanized IgG1-κ antibody targeting to C-type lectin domain family 4 member C (CLEC4C).

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.
