Two new processes were developed for the synthesis of 2,6-dichloro-3-methylaniline-Ph-UL-14C (1), a key intermediate in the synthesis of a DowElanco experimental product presently being considered for commercialization. Both processes afford product in much higher yields than that previously reported in the literature. One of the processes was subsequenly applied to the synthesis of methyl 6-chloroanthranilate-Ph-14C (12), used as an intermediate for a second potential product.
Efficient nitriding reagent and application thereof
-
Paragraph 0161-0163, (2021/03/31)
The invention discloses an efficient nitriding reagent and application thereof, wherein the nitriding reagent comprises nitrogen oxide, an active agent, a reducing agent and an organic solvent. By applying the nitriding reagent, nitrogen-containing compounds such as amide, nitrile and the like can be produced, and the method is simple in condition, low in waste discharge amount and simple in reaction equipment.

A new series of quinoline derivatives of combretastatin A-4 have been designed, synthesised and demonstrated as tubulin polymerisation inhibitors. These novel compounds showed significant antiproliferative activities, among them, 12c exhibited the most potent inhibitory activity against different cancer cell lines (MCF-7, HL-60, HCT-116 and HeLa) with IC50 ranging from 0.010 to 0.042 μM, and with selectivity profile against MCF-10A non-cancer cells. Further mechanistic studies suggest that 12c can inhibit tubulin polymerisation and cell migration, leading to G2/M phase arrest. Besides, 12c induces apoptosis via a mitochondrial-dependant apoptosis pathway and caused reactive oxygen stress generation in MCF-7 cells. These results provide guidance for further rational development of potent tubulin polymerisation inhibitors for the treatment of cancer.Highlights A novel series of quinoline derivatives of combretastatin A-4 have been designed and synthesised. Compound 12c showed significant antiproliferative activities against different cancer cell lines. Compound 12c effectively inhibited tubulin polymerisation and competed with [3H] colchicine in binding to tubulin. Compound 12c arrested the cell cycle at G2/M phase, effectively inducing apoptosis and inhibition of cell migration.
