IC50, namely conc. of 50% of cells death. It is important to note that the results reported in Table 5 have been obtained on specific cell lines (in some cases cancer cell lines), therefore they are only a preliminary indication and can not substitute the more complete studies that must ...
The mxiture is heated to convert the isomers to the compound (IV), which is hydrolysed to (I) in the presence of conc. H2SO4, at below degree C.GOSTELI,JACQUES,DR.

dilute H2SO4 or HCl. In the examples the copolymers are made in the above manner from (1) vinyl acetate, maleic acid and HgO in the presence of conc. H2SO4; (2, 4) as in (1) but with the addition of styrene and mercuric acetate instead of HgO; (3) as in (2) except maleic...
soln. of 1.1 mole L-phenylalanine methyl ester. HCl was neutralised with 71 g (Na2(CO3)2 extd. with (ClCH2)2 to give 1.05 mole L- phenylalanine methyl ester, which mixed with MeSO4H, prepd. by addn. of 0.105 mole conc. H2SO4 to 2.46 mole MeOH, and 0.258 mole I -HCl added ...
