The Role of the Acidity of N-Heteroaryl Sulfonamides as Inhibitors of Bcl-2 Family Protein–Protein Interactions
摘要:
Overexpression of the antiapoptotic members of the Bcl-2 family of proteins is commonly associated with cancer cell survival and resistance to chemotherapeutics. Here, we describe the structure-based optimization of a series of N-heteroaryl sulfonamides that demonstrate potent mechanism-based cell death. The role of the acidic nature of the sulfonamide moiety as it relates to potency, solubility, and clearance is examined. This has led to the discovery of novel heterocyclic replacements for the acylsulfonamide core of ABT-737 and ABT-263.

The novel 7-transmembrane receptor MrgX1 is located predominantly in the dorsal root ganglion and has consequently been implicated in the perception of pain. Here we describe the discovery and optimization of a small molecule agonist and initial docking studies of this ligand into the receptor in order to provide a suitable lead and tool compound for the elucidation of the physiological function of the receptor.
Adenosine receptors: synthesis, structure-activity relationships and biological activity of new 6-amino purine derivatives
The synthesis and evaluation of the biological activity of a series of pyridazin-3(2H)-one derivatives is reported. The compounds were tested in radioligand binding assays for affinity at A(1) and A(2A) adenosine receptors in bovine brain cortical membranes, and bovine brain striatal membranes, respectively. None of the compounds shows any affinity towards A(2A) receptor, while compounds in which the 6-chloro-pyridazin-3(2H)-one or 6-phenyl-pyridazin-3(2H)-one group is linked through a chain of two carbon atoms in the 6 position of the adenosine, show a good affinity towards A(1) adenosine receptor, particularly compound 8 in which a phenyl-pyridazinone group is present shows highest affinity with K-i values 6.6 nM.
