Since higher lipophilicity can facilitate penetration through the cell membrane and therefore increasing cytotoxicity in vitro, tanapsin monoacetate was synthesized (Fig.
4C), and similar results were obtained with the semi-synthetic derivative tanapsin monoacetate.
To determine the effect of tanapsin and tanapsin monoacetate on these proteases, cells were incubated in the presence of these sesquiterpene lactones.
The results indicate that tanapsin and tanapsin monoacetate significantly promote cleavage of procaspases-9, -7, -6 and -3 in all cell lines tested (Fig.
Partial synthesis of pregnene-4-triol-17(0), 200), 21-dione-3, 11 and pregnene-4-diol-17(0),21-trione-3,11,20 monoacetate
Sulfur's efficacy may be enhanced by using it in combination with either 2% resorcinol or 3% resorcinol monoacetate
Alfacetoanalogos amino acid composition of dl-3-methyl-2-oxivalerato 68mg calcium, 3-methyl-2-oxy-butyrate 86mg calcium, dl-2-hydroxy-4-methylthiobutyrate calcium 59mg, l-lysine monoacetate
