A novel pyridothiophene inhibitor of PTP1B was discovered by rational screening of phosphotyrosine mimics at high micromolar concentrations The potency of this lead compound has been improved significantly by medicinal chem. guided by x-ray crystallog. and mol. modeling. Excellent consistency has been observed between structure-activity relationships and structural information from PTP1B-inhibitor complexes. In the experiment, the researchers used many compounds, for example, Methyl 4-bromo-2-fluorobenzoate (cas: 179232-29-2Synthetic Route of C8H6BrFO2).
Methyl 4-bromo-2-fluorobenzoate (cas: 179232-29-2) belongs to organobromine compounds. Many of the organo bromine compounds are relatively nonpolar. Bromine is more electronegative than carbon (2.8 vs 2.5) and hence the carbon in a carbon闁艰京鐗梤omine bond is electrophilic in nature. Many of the alkyl bromine derivatives are excellent alkylating agents since bromides are good leaving groups. Tribromides, like tetrabutylammonium tribromide, are used as a solid source of bromine. N-bromosuccimide (NBS) is used for the selective bromination of allylic bonds.Synthetic Route of C8H6BrFO2
