SRPIN340 is primarily utilized in the field of medical research, particularly in studies focusing on the regulation of serine/arginine-rich protein kinases (SRPKs). It acts as an inhibitor of SRPK1, which plays a significant role in the splicing of pre-mRNA. By inhibiting SRPK1, SRPIN340 can modulate alternative splicing events, making it a valuable tool in understanding the molecular mechanisms underlying diseases such as cancer and viral infections. Researchers use SRPIN340 to explore potential therapeutic strategies, as abnormal splicing is often associated with various pathological conditions. Additionally, it aids in the investigation of angiogenesis, as SRPK1 is involved in the regulation of vascular endothelial growth factor (VEGF) splicing, a key factor in blood vessel formation. This makes SRPIN340 a promising compound for developing treatments targeting angiogenesis-dependent diseases.
