A tripodal amide based ligand, tris-{(2-carbamoyl-5-carbomethoxy-pyridine)- 2-ethyl}amine (H3L, 1), was synthesized and structurally characterized by single crystal X-ray diffraction. Investigation of the cation recognition behavior showed that the ligand has selective colorimetric sensing properties for cobalt(ii) ions by an obvious color change from colorless to yellow. To investigate the sensing mechanism of H3L for Co 2+ ions, UV-vis absorption spectroscopy and single-crystal structural analysis were performed. The mixture of the ligand and cobalt(ii) ions displayed selective colorimetric sensing properties for weak acid anions, such as CO32-, Ac-, HCO3-, SO32-, and PO43-. Detailed 1H NMR experiments revealed that the basicity of the anions played an important role in the intensity of the interaction between the ligand and anions. The structures of compounds CoL (2), Co-Ac-HL (3), H4L- NO3 (4), and H4L-ClO4 (5) were also determined by single crystal diffraction studies. This journal is the Partner Organisations 2014.

DNA-encoded combinatorial chemical library (DEL) technology, an approach that combines the power of genetics and chemistry, has emerged as an invaluable tool in drug discovery. Skeletal diversity plays a fundamental importance in DEL applications, and relies heavily on novel DNA-compatible chemical reactions. We report herein a phylogenic chemical transformation strategy using DNA-conjugated benzoyl hydrazine as a common versatile precursor in azole chemical expansion of DELs. DNA-compatible reactions deriving from the common benzoyl hydrazine precursor showed excellent functional group tolerance with exceptional efficiency in the synthesis of various azoles, including oxadiazoles, thiadiazoles, and triazoles, under mild reaction conditions. The phylogenic chemical transformation strategy provides DELs a facile way to expand into various unique chemical spaces with privileged scaffolds and pharmacophores.

Hypoxia-inducible factor-1 (HIF-1) is the chief transcription factor regulating hypoxia-driven gene expression. HIF-1 overexpression is associated with poor prognosis in several cancers and therefore represents an attractive target for novel antitumor agents. We explored small molecule inhibitors of the HIF-1 pathway. Using high-throughput-screening, we identified benzanilide compound 1 (IC50= 560 nM) as a seed. Subsequent extensive derivatization led to the discovery of compounds 43a and 51d, with anti-HIF-1 activities in vitro (IC50= 21 and 0.47 nM, respectively), and in vivo. Additionally, 43a (12.5-100 mg/kg) also displayed in vivo anti-tumor efficacy, without influencing body weight.
