Design, synthesis and biological evaluation of 6-aryl-1,6-dihydro-1,3,5-triazine-2,4-diamines as antiplasmodial antifolates

One-pot multistep synthesis of 1,6-dihydro-1,3,5-triazines displaying potent antiplasmodial activity in vitro.

Synthesis and Anti-Plasmodial Activity of 8β, 13β-Dihydroxypodocarpane Derivatives

8β,13β-Dihydroxypodocarpane and eight C-13 substituted derivatives were prepared from the precursor 8β-hydroxy-13-podocarpanone synthesised from the naturally occurring diterpene (+)-manool. The synthetic compounds exhibited a range of anti-plasmodial activities (IC501–29 μM) and only induced minimal haemolysis of erythrocytes at concentrations 50 and 100 μM. No changes in the morphology of erythrocytes were detected at sub-haemolytic concentrations.

Angiogenesis induced by "normal" human breast tissue: a probable marker for precancer

Normal human breast lobules, freshly isolated by precision microdissection of tissue stained with methylene blue chloride, were assayed for their ability to induce neovascularization (angiogenesis) in rabbit irises. Histologically, normal lobules from cancerous breast induced angiogenesis twice as often as lobules from noncancerous breasts, suggesting that preneoplastic transformation is diffuse.
