  A novel approach to functionalised 5,7,8,9-tetrahydropyrimido[4,5-b][1,4]diazepin-6-ones using intramolecular palladium-catalysed amidation

  摘要：

  The development of a novel palladium-catalysed amidation approach towards 5,7,8,9-tetrahydropyrimido[4,5-b][1,4]diazepin-6-one templates is highlighted. The route proceeds through the reaction of an amino amide, generated by 1,4-addition of an amine to an acrylamide, with 5-bromo-2,4-dichloropyrimidine and final palladium-catalysed cyclisation to provide the functionalised scaffold in up to 60% isolated yield over three steps. The route offers efficiency advantages over the previously reported nitro-reduction cyclisation approach to these molecules. It also provides alternative means to introduce bulky alkyl substituents at the amide nitrogen. The application of this route in the synthesis of a variety of analogues is described.

  The present invention relates to improved methods for inhibiting aberrant cell proliferation involving the scheduling of administration of Chk1 activators (e.g., chemotherapeutic agents) and Chk1 inhibitors. At least one Chk1 activator is administered at a dose and for a time sufficient to induce substantial synchronization of cell cycle arrest in proliferating cells. Upon achieving substantial phase synchronization, at least one Chk1 inhibitor is administered to abrogate the cell cycle arrest and induce therapeutic cell death. The invention is useful with any Chk1 activator and any Chk1 inhibitor, and finds application in treating or preventing cancerous and non-cancerous aberrant cell proliferation.
