The first asymmetric total synthesis of ophiorrhisine A (1), a new cyclic tetrapeptide isolated from Ophiorrhiza nutans, was accomplished via an intramolecular aromatic nucleophilic substitution reaction (IMSNAr) of a linear tripeptide to construct a 14-membered paracyclophane ring, resulting in confirmation of its structure and absolute configuration. The structure-activity relationship study of 1 and its derivatives demonstrated that some derivatives possessed cytotoxicity toward human cancer cell lines A549, HT29, and HCT116.
4-([1,2,4]Triazolo[1,5-a]pyridin-6-yl)-5(3)-(6-methylpyridin-2-yl)imidazole and -pyrazole derivatives as potent and selective inhibitors of transforming growth factor-β type i receptor kinase

A series of 4-([1,2,4]triazolo[1,5-a]pyridin-6-yl)-5(3)-(6-methylpyridin-2- yl)imidazoles and -pyrazoles 14a-c, 15a-c, 16a, 16b, 19a-d, 21a, and 21b has been synthesized and evaluated for their ALK5 inhibitory activity in an enzyme assay and in a cell-based luciferase reporter assay. Among them, the pyrazole derivative 21b inhibited ALK5 phosphorylation with an IC50 value of 0.018 μM and showed 95% inhibition at 0.03 μM in a luciferase reporter assay using HaCaT cells permanently transfected with p3TP-luc reporter construct. The 21b showed a high selectivity index of 284 against p38α MAP kinase. The binding pose of 21b generated by docking analysis reveals that it fits well into the ATP binding cavity of ALK5 by forming several hydrogen bond interactions.
