Thia- and Sulfonyl-Calix[4]Arene Methylphosphonous Acids: Synthesis, Structure, and Amino Acids Binding
摘要:
Thia- and sulfonyl-calix[4]arene methylphosphonous acids have been synthesized by hydrolysis of corresponding alkyl esters. Host-Guest complexation of the thiacalix[4]arene tetrakis-methylphosphonous acid with a series of 12 amino acids has been investigated by HPLC and molecular modeling methods. Stability constants of the complexes are within 53010,140M(1) in water contained solution.

Effect of thiacalix[4]arene platform on inhibition of alkaline phosphatase by macrocyclic phosphonate is presented in this article. Using tetrakis(dihydroxyphosphorylmethyl) derivatives we have found that phosphonate inhibitor on thiacalix[4]arene platform has displayed stronger inhibition properties towards alkaline phosphatases from bovine intestine mucosa, shrimp and human placenta than its structural calix[4]arene analogue. For elucidation of the molecular mechanism of the inhibition the tested macrocyclic compounds were docked computationally to the active site of alkaline phosphatase from shrimp. The role of thiacalix[4]arene platform in formation of the enzyme-inhibitor complex is discussed. Thiacalix[4]arene as molecular platform for design of alkaline phosphatase inhibitors
