Mechanism of Cellular 3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide (MTT) Reduction
TL;DR: Results suggest that MTT is taken up by cells through endocytosis and that reduced MTT formazan accumulates in the endosomal/lysosomal compartment and is then transported to the cell surface through exocytotic.

Antioxidant abietane diterpenoids from Salvia barrelieri
TL;DR: In this paper, the root extract of Algerian Salvia species Salvia barrelieri Ettling and its diterpenoids were investigated for potential antioxidant activity, and a new natural abietane diterphenoid 7-oxoroyleanone-12-methyl ether (1) was found to have the highest superoxide anion scavenging activity while inuroyleanol (7 ) showed both the highest 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging and inhibition of lipid peroxidation in β
