Abstract
While organophosphorus chemistry is gaining attention in a variety of fields, the synthesis of the phosphorus derivatives of amino acids remains a challenging task. Previously reported methods require the deprotonation of the nucleophile, complex reagents or hydrolysis of the phosphonate ester. In this paper, we demonstrate how to avoid these issues by employing phosphonylaminium salts for the synthesis of novel mixed n-alkylphosphonate diesters or amino acid-derived n-alkylphosphonamidates. We successfully applied this methodology for the synthesis of novel N-acyl homoserine lactone analogues with varying alkyl chains and ester groups in the phosphorus moiety. Finally, we developed a rapid, quantitative and high-throughput bioassay to screen a selection of these compounds for their herbicidal activity. Together, these results will aid future research in phosphorus chemistry, agrochemistry and the synthesis of bioactive targets.

Abstract
With the rapid increase in the population of obese individuals, obesity has become a global problem. Many kinds of chronic metabolic diseases easily caused by obesity have received increasing attention from researchers. People are also striving to find various safe and effective treatment methods as well as anti-obesity medicines. Pancreatic lipase (PL) inhibitors have received substantial attention from researchers in recent years, and PL inhibitors from natural products have attracted much attention due to their structural diversity, low toxicity and wide range of sources. They have been used in the intestinal tract, blood, and the central nervous system with no side effects, and these advantages could lead to a new generation of diet pills or health care products with great development potential. This article is mainly aimed at discussing the research of obesity drug treatment with PL inhibitors and offers a brief review of related properties and the use of PL inhibitors in the field of weight loss.

Kinetically-controlled mechanism-based isolation of metabolic serine hydrolases in active form from complex proteomes: butyrylcholinesterase as a case study. RSC Adv 2019; 9:38505-38519. [PMID: 35540231 PMCID: PMC9075836 DOI: 10.1039/c9ra07583f] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2019] [Accepted: 11/18/2019] [Indexed: 12/02/2022] Open
Abstract
In this work an activity-based probe containing a carbamate group was designed to isolate human butyrylcholinesterase (hBChE), a metabolic serine hydrolase (mSH), from complex proteomes. The method took advantage of the native interaction mechanism of mSHs with carbamate pseudo-substrates for temporarily capturing the enzyme on a resin functionalized with the carbamate probe and releasing the enzyme in active form after removal of the contaminating proteins. The isolation relied on the possibility of manipulating the carbamylation and decarbamylation kinetics favoring the former during the capture and wash steps and the latter in the release step. The designed probe captured and released all the active hBChE isoenzymes present in plasma with high selectivity (up to ∼2000-fold purification) and reasonable yields (17% to 36%). The parameters affecting the performance were the incubation time used in the load and elution steps, the plasma to resin volumetric ratio, the elution temperature and the nature and concentration of the eluting agent. The carbamate resin could be prepared either by coupling a fully synthesized probe with an activated resin or by building the probe onto the resin by a step-by-step procedure, without major differences in performance between the two routes. The prepared resins allowed to process up to about 8.5 mL of plasma per g of resin with constant performance. Since the method was based on the general catalytic cycle of mSHs, we expect this approach to be applicable to other enzymes of the family, by selecting a suitable target-selective feature to link to the carbamate group. The modulation of the equilibrium between carbamylation and decarbamylation kinetics is used to isolate a model metabolic serine hydrolase.![]()
