SRPIN340 is a highly selective inhibitor of SR protein phosphorylation with a Ki value of 0.89μM for SRPK1 [1].
SRPIN340 has been revealed to inhibit replication of HIV-1 and other viruses that require SR protein-dependent RNA processing for the propagation in HIV-1 transfected or infected Flp-In293 cell lines. In addition, SRPIN340 has been reported to significantly inhibit SRPK1 and SRPK2 kinase activity but not potently inhibit other SRPKs, such as Clk1 and Clk4 with a Ki value of 0.89μM for SRPK1. Besides, SRPIN340 has been exhibited to dose-dependently promote degradation of SRp75 which is necessary for HIV expression. Moreover, SRPIN340 has shown the inhibition of propagation of Sindbis virus with an IC50 of 60μM and the protection against the cytopathic effect of Sindbis virus [1].
