Hypoxia, a reduction in partial oxygen pressure, is a salient property of solid tumors. Hypoxia drives malignant progression and metastasis in tumors and participates in tumor resistance to radio- and chemotherapies. Hypoxia activates the hypoxia-inducible factor (HIF) family of transcription factors, which induce target genes that regulate adaptive biological processes such as anaerobic metabolism, cell motility and angiogenesis. Clinical evidence has demonstrated that expression of HIF-1 is strongly associated with poor patient prognosis and activation of HIF-1 contributes to malignant behavior and therapeutic resistance. Consequently, HIF-1 has become an important therapeutic target for inhibition by small molecules. Herein, we describe the design and synthesis of small molecules that inhibit the HIF-1 signaling pathway. Many of these compounds exhibit inhibitory activity in the nanomolar range. Separate mechanistic studies indicate that these inhibitors do not alter HIF-1 levels, but interfere with the HIF-1α/HIF-1β/p300/CBP complex formation by interacting with p300 and CBP.

“…[45][46][47][48][49] In particular, structural elaboration on heterocyclic compounds with terminal alkynyl/alkenyl functionalities using Sonogashira and Heck coupling reactions is quite interesting. [50][51][52][53][54][55][56] However, attempts are not made to investigate the structural elaboration of cyanopyridine derivatives using Pd-mediated Sonogashira and Heck coupling reactions via a one-pot multicomponent reaction (MCR).…”
