SART2 Inhibitors

Bisindolylmaleimide I is a potent and selective inhibitor of protein kinase C (PKC), which is involved in various signaling pathways. SART2, being implicated in cell cycle regulation and apoptosis, would have its function inhibited as PKC phosphorylation events necessary for the regulation of proteins involved in these processes are blocked.

Staurosporine is a potent inhibitor of many protein kinases, particularly those involved in cell cycle control and apoptosis, pathways where SART2 is involved. Its broad kinase inhibition profile would include kinases that phosphorylate SART2 or regulate its activity, leading to a functional inhibition of SART2's role in cell cycle progression.

LY294002 is a specific inhibitor of PI3K, a kinase involved in the AKT signaling pathway that contributes to cell survival and proliferation. Inhibition of PI3K would reduce AKT activation, thereby inhibiting downstream proteins that may include SART2 or its regulators, leading to a functional inhibition of SART2.

SP600125 is an inhibitor of c-Jun N-terminal kinase (JNK), which is involved in stress responses and apoptosis. By inhibiting JNK, the phosphorylation of proteins regulated by this kinase is reduced, which could include proteins that interact with or regulate SART2, thus inhibiting SART2 activity in the process.

SB203580 is a selective inhibitor of p38 MAP kinase, a protein involved in inflammatory responses and cell cycle arrest. Inhibition of p38 MAP kinase could lead to a reduction in the phosphorylation of substrates involved in these pathways, which could include SART2 or its regulatory proteins, thus resulting in a functional inhibition of SART2.

PD98059 is a selective inhibitor of the MAP kinase kinase (MEK), which is upstream of ERK in the MAPK/ERK pathway. This pathway is involved in cell division and differentiation, where SART2 may play a role. Inhibiting MEK would lead to decreased ERK activity, potentially inhibiting the phosphorylation of SART2 or its associated proteins.

Wortmannin is a potent inhibitor of PI3K like LY294002, and it exerts its inhibitory effects on the AKT pathway. Through the inhibition of this pathway, wortmannin would lead to decreased phosphorylation and activation of downstream proteins, which could include SART2 or its regulatory elements, inhibiting SART2's function.

Leflunomide is an inhibitor of dihydroorotate dehydrogenase (DHODH), which is important for pyrimidine synthesis. As pyrimidine synthesis is crucial for DNA synthesis and cell proliferation, leflunomide could lead to reduced availability of pyrimidines, which would functionally inhibit SART2 activity in proliferating cells.

Rapamycin inhibits the mTOR pathway, which is crucial for cell growth and proliferation. By inhibiting mTOR, rapamycin would reduce the activity of downstream targets that are essential for cell cycle progression, and this could include the functional inhibition of SART2 if it is involved in this pathway.

U0126 is an inhibitor of MEK like PD98059 and works to inhibit the MAPK/ERK pathway. By inhibiting MEK, U0126 prevents the activation of ERK and the subsequent phosphorylation of proteins involved in cell cycle regulation and differentiation, potentially including the inhibition of SART2 or its regulatory proteins.
