Vinylogous Amide Analogues of Diaminopimelic Acid (DAP) as Inhibitors of Enzymes Involved in Bacterial Lysine Biosynthesis
摘要:
[GRAPHICS]Vinylogous amides 5 and 6 have been synthesized from L-propargyl glycine and tested against diaminopimelate (DAP) enzymes involved in bacterial lysine biosynthesis, Both are reversible inhibitors of DAP D-dehydrogenase and DAP epimerase with IC50 values in the 500 muM range, Compound 5 shows competitive inhibition against the L-dihydrodipicolinate (DHDP) reductase with a K-i value of 32 muM, which is comparable to the planar dipicolinate 16 (K-i = 26 muM), the best known inhibitor of the enzyme.
