In the title compound, C(4)HCl(2)NO(3), the essentially planar (maximum deviation = 0.023 Å for the ring O atom) mol-ecules form N-H⋯O hydrogen bonds between mol-ecules lying about inversion centers, forming eight-membered rings with an R(2) (2)(8) motif in graph-set notation.

Unlabelled: Mesenchymal‒epithelial transition factor (c-Met), a receptortyrosine kinase (RTK), plays a vital role in cell proliferation, migration and invasion, and tumour metastasis.

Objective: With increasing duration of treatment, many tumours gradually develop drug resistance. Therefore, novel antitumour drugs need to be developed to treat patients with tumours.

ETV2/ER71, an ETS (E-twenty six) transcription factor, is critical for hematopoiesis and vascular development. However, research about the molecular mechanisms behind ETV2-mediated gene transcription is limited. Herein, we demonstrate that ETV2 and KDM4A, an H3K9 demethylase, regulate hematopoietic and endothelial genes.

Background: Amyotrophic lateral sclerosis (ALS) is a chronic, progressive disease that affects both upper and lower motor neurons. Some physicians have used traditional Chinese therapies (TCT) to treat ALS. However, there has been no systematic review or meta-analysis to evaluate the effectiveness and safety of TCT interventions.
