The transformation of simple hydrocarbons into more complex and valuable products has revolutionised modern synthetic chemistry. This type of reactivity has quickly become one of the cornerstones of modern catalysis . 92420-89-8, Name is (2S,3S,4S,5R,6R)-2-(Methoxycarbonyl)-6-(2,2,2-trichloro-1-iminoethoxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate, molecular formula is C15H18Cl3NO10. In a Article,once mentioned of 92420-89-8, Application of 92420-89-8
The synthesis and biological evaluation of novel prodrugs based on the cytotoxic antibiotic duocarmycin SA (1) for a selective treatment of cancer using a prodrug monotherapy (PMT) are described. Transformation of the phenol 8 with the glucuronic acid benzyl ester trichloroacetimidate 9b followed by reaction with DMAI·HCl (10) gives the glucuronide 11b, which is deprotected to afford the desired prodrug 4a containing a glucuronic acid moiety. In addition, the prodrug 4b with a glucuronic methyl ester unit is prepared. The cytotoxicity of the glucuronides is determined using a HTCFA-assay with IC50 values of 610 nM for 4a and 3300 nM for 4b. In the presence of beta-glucuronidase, 4a expresses an IC50 value of 0.9 nM and 4b of 2.1 nM resulting in QIC50 values of about 700 for 4a and 1600 for 4b.
