Background: As reported EGFR is a sialoglycoprotein with tyrosine kinase activity involved in control of cellular survival, multiplication, differentiation and metastasis. Dysregulation or aberrant expression of EGFR has been implicated in cell transformation and having oncogenic roles in a number of human cancers. Therefore EGFR has become a significant target for developing targeted therapy for cancer. Methods: A novel series of indole-3-carboxamide derivatives as EGFR inhibitors were designed, synthesized and evaluated for the anticancer activity in vitro against three EGFR high-expressed cancer cell lines (A549, HeLa, and SW480), one EGFR low-expressed cell line (HepG2) and one human liver normal cell line (HL7702) by MTT assay. Results: The target compounds 6c, 6f, 6i, 6j, 6l, 6r, 6u and 6x exhibited potent anticancer activities against the three tested cancer cell lines and weak cytotoxic effects on HepG2, which imply that the target compounds are probably effective in inhibiting EGFR. And they also did not show measurable activities in HL7702, which imply the target compounds are likely to overcome the nonspecific toxicity against normal cells. Particularly, the target compound 6x indicated equal to the positive control erlotinib. In addition, molecular docking studies demonstrated the target compound 6x may be the potential inhibitor to EGFR. Conclusion: A new EGFR inhibitor scaffold and a preliminary discussion on their SARs provide promising opportunities to guide further research on indole-3-carboxamide derivatives as novel anticancer agents.
Lead derivatization of ethyl 6-bromo-2-((dimethylamino)methyl)-5-hydroxy-1-phenyl-1H-indole-3-carboxylate and 5-bromo-2-(thiophene-2-carboxamido) benzoic acid as FabG inhibitors targeting ESKAPE pathogens

Our previous studies on FabG have identified two compounds 5-bromo-2-(thiophene-2-carboxamido) benzoic acid (A) and ethyl 6-bromo-2-((dimethylamino)methyl)-5-hydroxy-1-phenyl-1H-indole-3-carboxylate(B) as best hits with allosteric mode of inhibition. FabG is an integral part of bacterial fatty acid biosynthetic system FAS II shown to be an essential gene in most ESKAPE Pathogens. The current work is focussed on lead expansion of these two hit molecules which ended up with forty-three analogues (twenty-nine analogues from lead compound A and fourteen compounds from lead compound B). The enzyme inhibition studies revealed that compound 15 (effective against EcFabG, AbFabG, StFabG, MtFabG1) and 19 (inhibiting EcFabG and StFabG) had potency of broad-spectrum inhibition on FabG panel.

This disclosure generally relates to treating anemias. More specifically, the disclosure relates to use of muscarinic acetylcholine receptor subtype 4 antagonists, such as small molecule compounds, to promote self-renewal of burst forming unit erythroid (BFU-E) cells and treat anemias.
