A convenient synthesis of 5-deaza nonclassical antifolates: Reaction of cyanothioacetamide with sodium salts of 2-(hydroxymethylene)-1-cycloalkanones
摘要:
Condensation of cyanothioacetamide with sodium salts of 2-(Hydroxymethylene)-1-cycloalkanones afforded the corresponding pyridine-2(1H)-thiones 4. Compounds 4 served as a key intermediates for the synthesis of condensed 2,4-diaminopyrido[2,3-d]pyridines 7. Compounds 7 were of interest as potential inhibitors of dihydrofolate reductase.
Synthesis and antiproliferative activity of 2-chlorophenyl carboxamide thienopyridines
摘要:
3-Amino-2-arylcarboxamide-thieno[2,3-b]pyridines are a known class of antiproliferative compounds with activity against the phospholipase C enzyme. To further investigate the structure activity relationships of these derivatives a series of analogues were prepared modifying key functional groups. It was determined that modification of the 3-amino and 2-aryl carboxamide functionalities resulted in complete elimination of activity, whilst modification at C-5 allowed compounds of greater activity to be prepared.
