• Synthesis of diphenyl phosphonate analogues of tyrosine and tryptophan and derived peptides as chymotrypsin inhibitors
  作者：Carol Bergin、Robert Hamilton、Brian Walker、Brian J. Walker

  DOI：10.1039/cc9960001155

  日期：——

  The synthesis of α-aminophosphonate analogues of tyrosine and tryptophan, e.g. 4 and 5 respectively, and their incorporation into proline-containing dipeptides is reported; of the sequences synthesised, the dipeptide Z-Pro-TrpP(OPh)2 is the only derivative that functions as an irreversible inactivator of the serine proteinase chymotrypsin, in contrast, the tyrosine analogue 4 behaves as a competitive reversible inhibitor of the enzyme and the tryptophan analogue 5 behaves as a slow-binding inhibitor.

  报告了酪氨酸和色氨酸的 α-氨基膦酸盐类似物（如 4 和 5）的合成及其与含脯氨酸二肽的结合；在合成的序列中，二肽 Z-Pro-TrpP(OPh)2 是唯一的衍生物。在合成的序列中，Z-Pro-TrpP(OPh)2 是唯一一种可作为丝氨酸蛋白酶糜蛋白酶不可逆灭活剂的衍生物，相反，酪氨酸类似物 4 是该酶的竞争性可逆抑制剂，而色氨酸类似物 5 则是一种慢结合抑制剂。
• Towards the identification of unknown neuropeptide precursor-processing enzymes: Design and synthesis of a new family of dipeptidyl phosphonate activity probes for substrate-based protease identification

  Specific proteolytic processing of inactive precursors is an exquisite cellular mechanism that triggers the activation of numerous physiologic peptides and proteins. This process ensures the generation of biologically active peptides, such as many neuropeptides and peptide hormones, in the appropriate cellular compartments at the right time, and its failure leads to several pathological conditions. Identification of the proteases involved in this limited proteolysis is, therefore, an essential step for the subsequent establishment of new therapeutic targets. As a first effort along this line, we synthesized eight new dipeptidyl phosphonate activity-based probes and used them to explore the soluble proteome from mouse brain and pituitary gland for substrate-based protease identification both by in-gel analysis and mass spectrometry.

  Provided are phosphorus nitrogen flame retardants represented by Formula III, a method of preparing the flame retardants without using any solvent, and various materials comprising the flame retardants. Rb and Rc are independently of each other selected from hydrogen, substituted or unsubstituted alkyl such as C1-C18 alkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocyclic alkyl, substituted or unsubstituted heterocycles, substituted or unsubstituted aryl such as C6˜C18 aryl, substituted or unsubstituted heteroaryl such as C3˜C18 heteroaryl, and acyl radical. The invention exhibits numerous technical merits such as excellent flame retardant efficacy, good compatibility with polymers, lower migration to material surface, excellent hydrolysis resistance, low smoke and low toxicity during burning, simpler preparation process, fewer by-products, shorter reaction time, higher yield, and no environmental impact, among others.
