Synthesis of 2,3-disubstituted derivatives of pyrano-, thiopyrano-, and benzoannelated pyrido[2,3-b]thieno[3,2-d]pyrimidines
摘要:
A new methods have been developed for the synthesis of condensed pyrido[2,3-b]thieno[3,2-d]pyrimidines based on cyclic derivatives of 4-cyanopyridine-3-thiones. The presence of two different reactive functional groups NH2 and CONH gives the possibility of carrying out different conversions of thieno[2,3-b]pyridines.

The disclosure relates to aryl hydrocarbon receptor antagonists as well as methods of modulating aryl hydrocarbon receptor activity and expanding hematopoietic stem cells by culturing hematopoietic stem or progenitor cells in the presence of these agents. Additionally, the disclosure provides methods of treating various pathologies, such as cancer, by administration of these aryl hydrocarbon receptor antagonists. Additionally, the disclosure provides methods of treating various pathologies in a patient by administration of expanded hematopoietic stem cells. The disclosure further provides kits containing aryl hydrocarbon receptor antagonists that can be used for the expansion of hematopoietic stem cells. The disclosure further relates to pharmaceutical compositions comprising the compounds and methods of treating or preventing a disease in which aryl hydrocarbon receptor plays a role.
