One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, SDS of cas: 166591-85-1, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 166591-85-1, Name is 2-(tert-Butoxycarbonyl)-1,2,3,4-tetrahydroisoquinoline-1-carboxylic acid, molecular formula is C15H19NO4
Semi-synthesis and antitumor activity of 6-isomers of 5, 8-O-dimethyl acylshikonin derivatives
We recently discovered that 5, 8-O-dimethyl acylshikonin derivatives displayed the selectivity towards MCF-7 and no toxicity to normal cells. Herein, a series of the corresponding 6-isomers of 5, 8-O-dimethyl acylshikonin derivatives were synthesized starting from shikonin. In vitro evidence of the cytotoxicities indicated that most of thecompounds were more active than or comparative to shikonin and retained the selectivity against MCF-7, MDA-MB-231 besides no toxicity in the normal cells. Also, in vivo anticancer activity of the positional isomers 5p, 6c further showed that 6-isomers of 5, 8-O-dimethyl acylshikonin derivatives were more active than their corresponding 2-isomers. Thus, we may conclude that the position of the side chain of shikonin attached to 5,8-dimethoxy -1,4-naphthoquinone is associated with the antitumor activity.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. SDS of cas: 166591-85-1, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 166591-85-1, in my other articles.
