L 888607 Racemate is a selective antagonist of prostaglandin D2 receptor subtype 1 (DP1) (Kis: 132 nM and 17 nM for DP1 and thromboxane A2 receptor (TP), respectively).
R-82913 is a RNA-directed DNA polymerase inhibitor. R 82913 reduce 5-HT2 receptor-mediated DOI-head-shakes in mice. R82913 inhibited the replication of thirteen different strains of HIV-1 in CEM cells with a median IC50 of 0.15 microM. R82913 was 20-fold
I-SAP is a high affinity TPreceptor antagonist. At physiologic pH, I-SAP produces platelet shape change, but not aggregation, with an EC50 value of 9.7 nM. I-SAP binds to human platelets with the maximum binding obtained between pH 6.5 and pH 7.4. In washed human platelets, the Kd for I-SAP is 468 pM at pH 7.4 and 490 pM at pH 6.5.
