HGF/c-Met signalling pathway plays an important role in the development of cancers. A series of 6,7-dimethoxy-4-anilinoquinolines possessing benzimidazole moiety were synthesised and identified as potent inhibitors of the tyrosine kinase c-Met. Their in vitro biological activities against three cancer cell lines (A549, MCF-7, and MKN-45) were also evaluated. Most of these compounds exhibited moderate to remarkable potency. Among them, compound 12n showed the most potent inhibitory activity against c-Met with IC50 value of 0.030 ± 0.008 µM and it also showed excellent anticancer activity against the tested cancer cell lines at low micromolar concentration. Molecular docking verified the results and revealed the possible binding mode of the most promising compound 12n into the ATP-binding site of c-Met kinase.
X-linked hypohidrotic ectodermal dysplasia (XLHED) is a rare congenital genetic disorder caused by mutations in the ectodysplasin A gene, resulting in dysplasia or complete absence of teeth, hair, and sweat glands. XLHED is rarely diagnosed prenatally.We describe a case of XLHED diagnosed with prenatal sonography and umbilical cord blood gene testing.
Objectives: This study aimed to examine the application value of high-definition live (HDlive) flow combined with spatiotemporal image correlation (STIC) in the diagnosis of fetal inferior vena cava malformation (IVCM).Methods: Twenty cases of IVCMs were diagnosed using two-dimensional HDlive flow and HDlive flow combined with STIC and retrospectively analyzed to examine the impact of using HDlive flow combined with STIC in the diagnosis of IVCM.Results: HDlive flow combined with STIC detected one case of duplicated IVC, four cases of left IVC (two cases with complex malformations), and 15 cases of interrupted IVC (two cases of isolated IVC disconnection, five cases with left atrial heterogeneous syndrome, and eight cases with other complex malformations).
Conclusion:HDlive flow combined with STIC can help in the diagnosis of IVCM, and this technique has important clinical value.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
