Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 142-25-6, Name is N1,N1,N2-Trimethylethane-1,2-diamine, molecular formula is C5H14N2, belongs to amides-buliding-blocks compound, is a common compound. In a patnet, author is Li, Hu, once mentioned the new application about 142-25-6, Computed Properties of https://www.ambeed.com/products/142-25-6.html.
Novel derivatives of quinolizidine alkaloid (-)-cytisine were synthesised. ADME properties, cytotoxicity against HEK293 cells and activity against viruses of influenza A/California/07/09(H1N1)pdm09 virus (IAV) and human parainfluenza virus type 3 (HPIV3) were evaluated. It was shown, that 9-carboxamides of methylcytisine (with phenyl and allyl urea’s fragments) are most active compounds against IAV probably due to predicted in silico peculiarity of their interactions with the 4R7B active site of IAV neuraminidase. Indexes of selectivity (SI) calculated as ratio of CC50/IC50 of these ureas are 47 and 59 correspondingly. It was also found, that derivatives obtained from allyl isocyanate and (-)-cytisine or 9,11-dibromocytisine are able to inhibit a reproduction of HPIV3 with SI = 58 and 95. Moreover, last compound – (1 R,5R)-N-allyl-9,11-dibromo-8-oxo-1,5,6,8-tetrahydro-2H-1,5-methanopyrido[1,2-a][1,5]diazocine-3(4H)-carboxamide with two bromine atom in 2-pyridone core of starting (-)-cytisine molecule, demonstrated high activity against HPIV3 (SI = 95) and moderate activity against IAV (SI = 16).
We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 142-25-6. The above is the message from the blog manager. Computed Properties of https://www.ambeed.com/products/142-25-6.html.
