  摘要：

  已经制备了一系列的2，4-二氨基-5-（叠氮芳基）-6-烷基嘧啶。叠氮化物（36）（MZP）可以通过硫醇试剂还原为相应的胺（28），但是当一系列叠氮基苯基衍生物与水合肼一起加热时，会发生还原脱叠作用。在三氟乙酸-三氟甲磺酸混合物中于0°C降解叠氮化物（36）提供了一种将庞大的三氟甲基磺酰氧基取代基引入到5-芳基取代基的受阻邻位中的方法。由叠氮化物（36）和平面类似物2,4-二氨基-6-叠氮喹啉（70）的热解和光解形成的产物）衍生自三重态腈反应性中间体。

  Development of 2,4-Diaminopyrimidines as Antimalarials Based on Inhibition of the S108N and C59R+S108N Mutants of Dihydrofolate Reductase from Pyrimethamine-Resistant Plasmodium falciparum

  摘要：

  The reduced binding of pyrimethamine to Ser 108Asn (S108N) mutants of parasite dihydrofolate reductase (DHFR), which forms the basis of resistance of Plasmodium falcipartum to pyrimethamine, is largely due to steric constraint imposed by the bulky side chain of N108 on Cl of the 5-p-Cl-phenyl group. This and other S108 mutants with bulky side chains all showed reduced binding to pyrimethamine and cycloguanil. Less effect on binding to some bulky mutants was observed for trimethoprim, with greater flexibility for the 5-substituent. S108N DHFR also binds poorly with other pyrimethamine derivatives with bulky groups in place of the p-Cl, and the binding was generally progressively poorer for the double (C59R+S108N) mutant. Removal of the p-Cl or replacement with m-Cl led to better binding with the mutant DHFRs. Pyrimethamine analogues with unbranched hydrophobic 6-substituents showed generally good binding with the mutant DHFRs. A number of compounds were identified with high affinities for both wild-type and mutant DHFRs, with very low to no affinity to human DHFR. Some of these compounds show good antimalarial activities against pyrimethamine-resistant P. falciparum containing the mutant DHFRs with low cytotoxicity to three mammalian cell lines.

  A series of 2,4-diamino-5-(azidoaryl)-6-alkylpyrimidines has been prepared. The azide (36)(MZP) can be reduced by thiol reagents to the corresponding amine (28) but reductive deazidation occurred when the series of azidophenyl derivatives was heated with hydrazine hydrate. Degradation of azide (36) in a trifluoroacetic acid–trifluoromethanesulphonic acid mixture at 0 °C affords a means of introducing
