Effective therapeutic agents are highly desired for immune-mediated allergic diseases. Herein, we report the design, synthesis, and structure-activity relationship of an o-aminopyridinyl alkyne series as novel orally bioavailable antiallergic agents, which was identified through phenotypic screening. Compound optimization yielded a highly potent compound 36, which effectively suppressed mast cell degranulation in a dose-dependent manner (IC50, 2.54 nM for RBL-2H3 cells; 48.28 nM for peritoneal mast cells (PMCs)) with a good therapeutic index. It also regulated the activation of FcεRI-mediated downstream signaling proteins in IgE/Ag-stimulated RBL-2H3 cells. In addition, 36 exhibited excellent in vivo pharmacokinetic properties and antiallergic efficacy in both passive systemic anaphylaxis (PSA) and house dust mite (HDM)-induced murine models of pulmonary allergic inflammation. Furthermore, preliminary anal. of the kinases profile identified Src-family kinases as potential targets for 36. Compound 36 may serve as a new valuable lead compound for future antiallergic drug discovery. In the experiment, the researchers used many compounds, for example, 3-Iodo-2-methylbenzoic acid (cas: 133232-56-1Synthetic Route of C8H7IO2).
3-Iodo-2-methylbenzoic acid (cas: 133232-56-1) belongs to iodide derivatives. Organic iodides are widely used in organic synthesis. Halogenation of aromatic hydrocarbons is a very important reaction via an electrophilic aromatic substitution. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond.Synthetic Route of C8H7IO2
