fd1

FD-IN-1 is a factor D (FD) inhibitor with an IC50 of 12 nM.FD-IN-1 also inhibits factor XIa (FXIa) and Tryptase β2 with IC50s of 7.7 and 6.5μM, respectively. Complement FD, a highly specific S1 serine protease, plays a central role in the alternative complement pathway of the innate immune system.

Tegadifur (40497S) is an orally available antitumor compound with antimetabolic effects, often used with uracil and in the treatment of rectal adenocarcinoma.

FD1024 is a potent PIM inhibitor, displaying inhibitory concentrations (IC50s) of 1.96 nM, 38.9 nM, and 4.17 nM for PIM1, PIM2, and PIM3, respectively. It demonstrates significant antiproliferative effects on several AML cell lines, with IC50 values of 0.16 μM for EOL-1, 0.12 μM for MV-4-11, 1.05 μM for KG-1, and 1.39 μM for MOLM-16. Additionally, FD1024 has shown antitumor efficacy in murine models [1].
