disease caused by Trypanosomabruceirhodesiense and Trypanosomabrucei gambiense which seriously affects human health in Africa. Current therapies present limitations in their application, parasite resistance, or require further clinical investigation for wider use. Our work herein describes the design and syntheses of novel antitrypanosomal 4-phenyl-6-(pyridin-3-yl)pyrimidines, with compound 13, the 4-
Combination of the Claisen-Schmidt reaction, the Michael addition, and the Hantzsch reaction in the synthesis of 2,6′-bis-aryl-3,4′-bipyridines

Pyridine-3-carbaldehyde reacted with 1-(aryl)ethan-1-ones to give 1,5-diaryl-3-(pyridin-3-yl)pentane-1,5-diones, which were further converted to 2′,6′-bis-aryl-3,4′-bipyridines.
Several substituted3‐aryl‐1‐(4‐aryl‐2‐thiazolyl)‐5‐(3‐pyridyl)‐2‐pyrazolines were synthesized by reacting substituted3‐aryl‐5‐(3‐pyridyl)‐1‐thiocarbamoyl‐2‐pyrazolines with phenacyl bromide in ethanol. The structures of all compounds were confirmed by IR, 1H‐NMR, mass spectral data and elemental analyses. The antihypertensive activity of compounds was examined by the tail‐cuff method and compared
