  Quinoxaline chemistry Part 9. Quinoxaline analogues of trimetrexate (TMQ) and 10-propargyl-5,8-dideazafolic acid (CB 3717) and its precursors. Synthesis and evaluation of in vitro anticancer activity

  摘要：

  Eighteen quinoxalines bearing a methyleneanilino or methyleneaminobenzoylglutamate group on position 6 of the ring and various lipophilic substituents on positions 2 and 3 were prepared in order to discover if their structural analogy with both trimetrexate (TMQ) and 10-propargyl-5,8-dideazafolic acid (CB 3717) might display in vitro anticancer activity. Among these, 12 compounds were selected at the National Cancer Institute, Bethesda, MD, USA; they exhibited moderate (4b,d,i,l,m and 8) to strong (4f,h and 5a,e) cell-growth inhibition at a concentration of 10(-4) M. Interesting selectivities were also recorded between 10(-8) and 10(-6) M. These analogues proved to be less potent inihibitors of tumor cells than other classical and non-classical antifolate analogues previously described by us. (C) 1998 Elsevier Science S.A.

• Synthesis of 2-Aminoquinoxalines via One-Pot Cyanide-Based Sequential Reaction under Aerobic Oxidation Conditions

  日期：2014.2.7

  A highly efficient synthesis of 2-aminoquinoxalines has been developed via the one-pot two-step cyanide-mediated sequential reactions of ortho-phenylenediamines with aldehydes under aerobic oxidation conditions. A variety of substrates, including aliphatic aldehydes bearing acidic a-protons, are applicable to this protocol and afford the desired 2-aminoquinoxalines in high yields.
