In the present work, we described convenient methods for the synthesis of N‐thiophosphorylated 3‐(4‐aminophenyl)‐coumarin‐7‐O‐sulfamates as steroid sulfatase (STS) inhibitors. To design the structures of the potential STS inhibitors, molecular modeling techniques were used. A computational docking method was used to determine the binding modes of the synthesized inhibitors as well as to identify potential
Synthesis and Properties of 2-S-[2'-(N,N-Dialkylamino)ethyl]thio-1,3,2-dioxaphosphorinane 2-Oxide and of the Corresponding Quaternary Derivatives as Potential Nontoxic Antiglaucoma Agents
A new series of cyclic organophosphorus esters, 2-S-[2'-N,N-dialkylamino)ethyl]thio-1,3,2-dioxaphosphorinane 2-oxide and their quaternary derivatives, was synthesized and studied as potential antiglaucoma agents. Thes compounds inhibit acetylcholinesterase (E.C.3.1.1.7)at a bimoecular rate constant (ki) in the range of 10(3)-10(4) M-1 min-1. Values of the affinity (K) and phosphorylation (k') rate constants for this enzyme indicate that k' is responsible for the relatively low values of ki as compared with similar data for the open-chain analogues, O,O-diethyl phosphorothiolates (10(6) M-1 min-1). The mammalian toxicity of the new compounds in terms of acute LD50 values in mice is 1-3 x 10(3) less than that of phospholine, an open-chain analogue. In an initial clinical trial, one member of the new series (alkyl = C2H5) caused a significant decrease of intraocular pressure in aphakic glaucoma, while phospholine proved to be ineffective.

Thiophosphorylated derivatives of meta- and ortho-hydroxybenzaldehydes take part in one-step, acid-catalyzed condensations with resorcinol and its derivatives. As a result, new calix[4]resorcinols, which contain four 2-thioxo-1,3,2-dioxaphosphorinane fragments on the aromatic substituents of the calixarene matrix, have been synthesized. In this case, macrocyclic products are formed as rccc- (cone or boat conformation) and/or rctt- (chair conformation) diastereomers, the ratio of which depends on the structure of the starting reagents. The obtained products have been isolated and their structures determined by NMR methods and single-crystal X-ray diffraction. The spectral differences of conformational isomers of the prepared macrocycles have been demonstrated. (C) 2014 Elsevier Ltd. All rights reserved.
