Abstract
In this study, a series of new hybrid molecules containing two important functional groups on the same skeleton were designed. 4-Hydroxybenzaldehyde and its two different derivatives were converted into their respective sulphonates by interacting with tosylchloride and methanesulfonyl chloride. Then, the desired molecules were synthesized by adding diethoxyphosphonate to the aldehyde group. Also, novel synthesis of hybrid compounds (4a-c and 5a-c) were tested toward some metabolic enzymes like carbonic anhydrase I and II isoenzymes (hCA I and hCA II) and acetylcholinesterase (AChE) enzyme. The synthesis of hybrid compounds (4a-c and 5a-c) showed Ki values of in range of 25.084±4.73-69.853±15.19 nM against hCA I, 32.325±1.67-82.761±22.73 nM against hCA II and 1.699±0.25 and 3.500±0.91 nM against AChE. For these compounds, compound 4c showed maximum inhibition effect against hCA I and hCA II isoenzymes and compound 5b showed maximum inhibition effect against AChE enzyme. By performing docking studies of the most active compounds for their binding modes and interactions were determined.

Abstract
The potentialities of condensation of α-ketophosphonates with primary amines for direct
synthesis of α-iminophosphonates have been revealed. Diesters of α-ketophosphonic acids react with
the primary amines by two competitive pathways: with a formation of α-iminophosphonates or a C-P
bond cleavage resulting in a hydrogen phosphonate and an acylated amine. In many cases, the latter
undesirable pathway is dominant, especially for more nucleophilic alkyl amines. Using metallic salts
of α-ketophosphonates avoids the C-P bond cleavage, allowing direct preparation of α-phosphorylated
imines by the reaction with primary amines. This strategy provides an atom economy single-stage synthesis
of iminophosphonates – precursors of bio relevant phosphorus analogs of α-amino acids. Methyl
sodium iminophosphonates, bearing aryl or heteryl substituents at the imino carbon atom exist in
solutions at room temperature as an equilibrium mixture of Z- and E-isomers. A configuration of the
C=N bond can be controlled by the solvent: changing the aprotic dipolar solvent DMSO-d6 by water
or alcohols leads to the change from a predominant Z-isomer to almost an exclusive E-form. In contrast,
diesters of the respective iminophosphonates exist in non-protic solvents predominantly in Econfiguration.
The solvent effect on E-Z stereochemistry is demonstrated by DFT calculations.

Phosphonic Acid Analogues of Phenylglycine as Inhibitors of Aminopeptidases: Comparison of Porcine Aminopeptidase N, Bovine Leucine Aminopeptidase, Tomato Acidic Leucine Aminopeptidase and Aminopeptidase from Barley Seeds. Pharmaceuticals (Basel) 2019; 12:ph12030139. [PMID: 31533309 PMCID: PMC6789573 DOI: 10.3390/ph12030139] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2019] [Revised: 09/13/2019] [Accepted: 09/16/2019] [Indexed: 12/22/2022] Open
Abstract
The inhibitory activity of 14 racemic phosphonic acid analogs of phenylglycine, substituted in aromatic rings, towards porcine aminopeptidase N (pAPN) and barley seed aminopeptidase was determined experimentally. The obtained patterns of the inhibitory activity against the two enzymes were similar. The obtained data served as a basis for studying the binding modes of these inhibitors by pAPN using molecular modeling. It was found that their aminophosphonate fragments were bound in a highly uniform manner and that the difference in their affinities most likely resulted from the mode of substitution of their phenyl rings. The obtained binding modes towards pAPN were compared, with these predicted for bovine lens leucine aminopeptidase (blLAP) and tomato acidic leucine aminopeptidase (tLAPA). The performed studies indicated that the binding manner of the phenylglycine analogs to biLAP and tLAPA are significantly similar and differ slightly from that predicted for pAPN.
