  The synthesis and biological activity of a series of 2,4-diaminopyrido[2,3-D]pyrimidine based antifolates as antineoplastic and antiarthritic agents

  摘要：

  A new series of 2,4-diaminopyrido[2,3-d]pyrimidine based antifolates 1-3 were synthesized through an efficient conversion of 2-pivaloyl-4-oxo-6-ethynylpyrido[2,3-d]pyrimidine 5 to the corresponding 4-amino analog 7 via the activated 1,2,4-triazole intermediate 6. Compound 7 was used as the key intermediate for the preparation of the final products. The detailed biological evaluation of these compounds both as antineoplastic and antiarthritic agents will be discussed. (C) 1998 Elsevier Science Ltd. All rights reserved.
