• Examining the structure-activity relationship of benzopyran-based inhibitors of the hypoxia inducible factor-1 pathway

  Many forms of solid tumor have a characteristic feature known as hypoxia, which describes a low or nonexistent presence of oxygen in the cellular microenvironment. This decrease in oxygen causes activation of the hypoxia inducible factor (HIF) pathway, which activates the transcription of many genes that cause cell proliferation, metastasis, increased glycolysis and angiogenesis. Increased HIF expression has been linked with poor patient prognosis, increased malignancy, and therapeutic resistance. Previous work in our lab has identified 1 and 2 as inhibitors of the HIF pathway, specifically as disrupters of the p300-HIF-1 alpha complex formation. A library of sulfonamide analogs has been designed and synthesized with the intent of examining the SAR of this series of compounds and improving potency and physicochemical properties as compared with lead compounds 1 and 2. At the end, we have achieved a thorough understanding of the structural features critical for future optimization work. (C) 2017 Elsevier Ltd. All rights reserved.

  The metabolic stability and selectivity of a series of CCR8 antagonists against binding to the hERG ion channel and cytochrome Cyp2D6 are studied by principal component analysis. It is demonstrated that an efficient way of increasing metabolic stability and selectivity of this series is to decrease compound lipophilicity by engineering nondesolvation related attractive interactions with CCR8, as rationalized by three-dimensional receptor models. Although Such polar interactions led to increased compound selectivity, such a strategy could also jeopardize the DMPK profile of compounds. However, once increased potency is found, the lipophilicity can be readjusted by engineering hydrophobic substituents that fit to CCR8 but do not fit to hERG. Several such lipophilic fragments are identified by two-dimensional fragment-based QSAR analysis. Electrophysiological measurements and site-directed mutagenesis studies indicated that the repulsive interactions of these fragments with hERG are caused by steric hindrances with residue F656.
