Abstract: Serine proteases are involved in the blood coagulation cascade- composed
of intrinsic, extrinsic, and common pathways affecting coagulation responses. Among
the three pathways of the blood coagulation cascade involving serine proteases, this
review focuses on serine protease inhibitors of the understudied extrinsic pathway,
which is responsible for bleeding and bleeding complications targeting the (activated
factor VII-Tissue Factor) fVIIa-TF complex. In lieu of our search for fVIIa-soluble TF
(fVIIa-sTF) inhibitors or scaffolds, we review the serine protease inhibitors present as
synthetic and natural products, which are involved in the blood coagulation cascade, and compare them with the serine
protease peptide inhibitors found in toxic Microcystis cyanobacteria. Some scaffolds for the extrinsic pathway as inhibitors
from the toxic Microcystis cyanobacteria will be identified in the review.
