Ojha, K. G. published the artcileSynthesis and antibacterial activity of some substituted phenothiazin-3-ones, Related Products of pyridine-derivatives, the publication is International Journal of Chemical Sciences (2003), 1(4), 347-350, database is CAplus.
1,2,4-Trihalophenothiazin-3-ones were prepared by condensing 2-aminobenzenethiols with chloranil/bromanil in 1:1 molar ratio. These compounds on refluxing with aryl amine and anhydrous NaOAc in EtOH gave substituted 2-arylaminophenothiazin-3-ones, which exhibited antibacterial activity.
International Journal of Chemical Sciences published new progress about 18437-58-6. 18437-58-6 belongs to pyridine-derivatives, auxiliary class Pyridine,Amine, name is 4-Amino-2-picoline, and the molecular formula is C6H8N2, Related Products of pyridine-derivatives.
