Highly convergent synthesis of a rebeccamycin analog with benzothioeno(2,3-a)pyrrolo(3,4-c)carbazole as the aglycone

A highly convergent, scalable synthesis of the rebeccamycin analog 2 was demonstrated in seven steps and 31% overall yield based on the N-protected building block dibromomaleimide 7. The practical synthesis of other two building blocks, 5,6-difluoro-3-ben

Novel 2-amino-4-oxo-5-arylthio-substituted-pyrrolo[2,3-d]pyrimidines as nonclassical antifolate inhibitors of thymidylate synthase

A series of 17 novel 2-amino-4-oxo-5-[(substituted phenyl)thio]pyrrolo[2,3- d]pyrimidines were synthesized as potential inhibitors of thymidylate synthase (TS) and as antitumor agents. The analogues contain a variety of electron withdrawing substituents on the phenyl ring of the side chain and were evaluated as inhibitors of human TS (hTS) and Escherichia coli TS and of human and E. coli dihydrofolate reductase (DHFR). The analogues 14, 17, and 18 were potent inhibitors of hTS with IC50 values of 0.28, 0.21, and 0.22 μM, respectively, and were more potent than the clinically used ZD1694, 2 and LY231514, 3 against human TS.
