Having gained chemical understanding at molecular level, chemistry graduates may choose to apply this knowledge in almost unlimited ways, as it can be used to analyze all matter and therefore our entire environment. 89-63-4, Name is 4-Chloro-2-nitroaniline, SMILES is NC1=CC=C(Cl)C=C1[N+]([O-])=O, belongs to naphthyridine compound. In a document, author is Chaves, Otavio Augusto, introduce the new discover, Application In Synthesis of 4-Chloro-2-nitroaniline.
The present work reports the biological assays between synthetic BF2-naphtyridine complexes and four proteins: human serum albumin (HSA). calf-thymus DNA (CT-DNA), tyrosinase and acetylcholinesterase enzymes via spectroscopic analysis at physiological conditions, combined with molecular docking simulations. The BF2-complexes presented spontaneous and moderate binding ability to HSA through the ground-state association (static fluorescence quenching mechanism). The main binding site is Sudlow’s site I (subdomain IIA) and the binding does not perturb significantly both secondary and surface structure of HSA. Despite BF2-complexes showed good binding ability with HSA, these compounds presented weak intercalative ability with CT-DNA (the most conventional and simple model to preliminary studies), except in the case of 1 h, which suggested that the presence of electronic donor groups in both aromatic ring moieties of BF2-complex structure can increase the intercalative ability for DNA strands. Competitive binding displacement assays in the presence of methyl green and molecular docking calculations indicated that the studied compounds interact preferentially in the major groove of DNA In addition, the assayed compounds presented the ability to activate or inhibit both tyrosinase (the decontrolled activity can induce melanoma carcinoma) or AChE (involved in reactions related to the function of neurotransmitters) enzymes.
