Background:
TAPI-1 is an inhibitor of tumour necrosis factor with IC50 value of 8.09 μM [1].
TAPI-1 is an inhibitor of TACE/ADAM17 which catalyzes the cleavage of full-length APP to the soluble N-terminal fragment (sAPPα). The release of sAPPα has been reported to be a receptor-coupled process increased by the stimulation of muscarinic receptors. In HEK293 cells, treatment of TAPI-1 resulted in an inhibition of increased sAPPα which was induced by the expressing of M3 subtype. The IC50 values of TAPI-1 in the inhibition of M3-increased sAPPα and constitutive release of sAPPα were 3.61 μM and 8.09 μM, respectively. Besides APP, TAPI-1 was also found to have inhibitory effects on the release of TNF-α, IL6R, TNFRI and TNFRII with IC50 values of 50-100, 5-10, 5-10 and 25-50 mM, respectively [1, 2].
