Structural Insights into the Hydrogen-Bonding and Folding Pattern in Ant-Ant-Pro-Gly Tetrapeptides

In this paper, we provide structural insights into the hydrogen-bonding and folding pattern in Ant-Ant-Pro-Gly tetrapeptides (Ant: anthranilic acid; Pro: proline; and Gly: glycine). Comparison of the C-terminal esters and their amide analogs revealed strikingly different H-bonding networks. Whereas the ester analogs displayed an open structure without terminal H-bonding interactions, the amide analogs showed a completely folded structure. Structural details were revealed by using a combination of X-ray crystal structure studies and NOE-based molecular dynamics (MD) simulation studies.

Synthesis of 2-Aryl-4H-3,1-Benzoxazin-4-ones: A Class of α-Chymotrypsin Inhibitors

Twenty one derivatives of 2-aryl-4H-3,1-benzoxazin-4-one were synthesized and their potential therapeutically significance and structureactivity relationship were tested against α-chymotrypsin. Majority of synthesized compounds showed significant in vitro α-chymotrypsin inhibitory properties having IC50values in the range of 5.42 ± 1.66 - 41.27 ± 1.33 μM, whereas standard inhibitor chymostatin have IC50 value 7.13 ± 1.06 μM. In the present series compounds 2-(2-fluorophenyl)-4H-3,1-benzoxazin-4-one (3h), 2-(2-bromophenyl)-4H-3,1- benzoxazin-4-one (3n) and 2-(1-naphthyl)-4H-3, 1-benzoxazin-4-one (3t) with IC50values 7.22 ± 0.75, 6.99 ± 0.29 and 5.42 ± 1.66 μM, respectively were found to be most active members of series, even better than standard inhibitor a-chymostatin.
