- Pyrrolo[3,2-c]pyridine derivatives with potential inhibitory effect against FMS kinase: in vitro biological studies
-
A series of eighteen pyrrolo[3,2-c]pyridine derivatives were tested for inhibitory effect against FMS kinase. Compounds 1e and 1r were the most potent among all the other tested analogues (IC50 = 60 nM and 30 nM, respectively). They were 1.6 and 3.2 times, respectively, more potent than our lead compound, KIST101029 (IC50 = 96 nM). Compound 1r was tested over a panel of 40 kinases including FMS, and exerted selectivity against FMS kinase. It was further tested against bone marrow-derived macrophages (BMDM) and its IC50 was 84 nM (2.32-fold more potent than KIST101029 (IC50 = 195 nM)). Compound 1r was also tested for antiproliferative activity against a panel of six ovarian, two prostate, and five breast cancer cell lines, and its IC50 values ranged from 0.15–1.78 μM. It possesses also the merit of selectivity towards cancer cells than normal fibroblasts.

- Cell-based biological evaluation of a new bisamide FMS kinase inhibitor possessing pyrrolo[3,2-c]pyridine scaffold
-
A bisamide compound 1 possessing the pyrrolo[3,2-c]pyridine nucleus was synthesized and biologically evaluated. It was tested for kinase inhibitory activity over a panel of 47 kinases, and its selectivity toward the FMS kinase was accidentally discovered. Compound 1 was tested over a panel of seven ovarian, two prostate, and six breast cancer cell lines at a single dose concentration of 10μM and showed high activity. It was further tested in a 5-dose mode to determine its IC50 and total growth inhibition (TGI) values over the 15 cell lines. Compound 1 showed high potency on the submicromolar scale and good efficacy. The cytotoxic effect of compound 1 over peritoneal macrophages was also investigated. Compound 1 demonstrated higher selectivity against different cancer cell lines compared with HS-27 fibroblasts.

- Design, synthesis, and antiproliferative activity of new 1H-pyrrolo[3,2-c]pyridine derivatives against melanoma cell lines. Part 2
-
A new series of diarylureas and diarylamides possessing 1H-pyrrolo[3,2-c]pyridine scaffold was designed and synthesized. Their in vitro antiproliferative activities against A375P human melanoma cell line and NCI-9 human melanoma cell line panel were tested. All the target compounds, except three amino derivatives 8g, h and 9h, demonstrated superior potencies against A375P to Sorafenib. In addition, compounds 8a and 9b-f demonstrated higher potencies than Vemurafenib against A375P. Compounds 8c and 9b were 7.50 and 454.90 times, respectively, more selective towards A375P melanoma cells over NIH3T3 fibroblasts. Furthermore, compounds 8d, e and 9a-d, f demonstrated very high potencies against the nine tested melanoma cell lines at the NCI. The bisamide derivatives 9a-c, f showed 2-digit nanomolar IC50 values over different cell lines of the NCI-9 melanoma cell lines.

- Discovery of a new potent bisamide FMS kinase inhibitor
-
FMS is a type III receptor tyrosine kinase that binds to the macrophage or monocyte colony stimulating factor (M-CSF or CSF-1). Signal transduction through that binding results in survival, proliferation, and differentiation of monocyte/macrophage lineage. In this study, we report the discovery of a new potent inhibitor of FMS kinase. The synthesized pyrrolo[3,2-c]pyridine derivative (compound 1) was initially tested at a single concentration of 1 μM against 47 different kinases. At this concentration, the% inhibitions of the enzymatic activities of FMS and KDR kinases were 90% and 71%, respectively, while the inhibition in activity was less than 58% for all of the other kinases. For compound 1, the IC50 values against FMS and KDR were 96 and 1058 nM, respectively. So, compound 1 was found to be 11 times more selective for FMS kinase than KDR kinase. Compound 1 can be used as a promising lead for the development of new selective inhibitors of FMS kinase, which can be used as useful therapeutic tools for treatment of several inflammatory and cancer disorders.
