Enantioselective synthesis and antiproliferative properties of an ilmofosine analog, 2'-(trimethylammonio)ethyl 3-(hexadecyloxy)-2- (methoxymethyl)propyl phosphate, on epithelial cancer cell growth

An asymmetric synthesis of the 1-alkyloxy analog of the thioether phosphocholine ilmofesine (BM 41.440, rac-1), 2'-(trimethylammonio)ethyl 3- (hexadecyloxy)-2-(methoxymethyl)propyl phosphate (2), is described. Stereoselectivity was obtained in an asymmetric hydroborationoxidation sequence carried out on a 2,2-disubstituted 1-alkene, 3-(hexadecyloxy)-2- (methoxymethyl)-1-propene (9), which was prepared by starting with either ethyl acrylate or ethyl α-(hydroxymethyl)acrylate (3). (R)- and (S)-2 and rac-1 were highly effective in inhibiting the proliferation of the breast adenocarcinoma cell line MCF-7 (IC50, 2 μM), moderately effective against A549 (non-small-cell lung adenocarcinoma) (IC50, 8-10 μM), and less effective against A427 (large cell lung carcinoma) (IC50, ~20 μM). The in vitro cytotoxicity against the three epithelial cancer cell lines was independent of the configuration about C-2 of the glycerol backbone of 2 and was also not altered by substitution of oxygen for sulfur in the sn-1 ether linkage of ilmofosine.

THE SYNTHESIS OF VOLATILE STREPTOMYCES LACTONES

A synthetic pathway to the volatile streptomyces lactones has been developed using as a key step sequential addition / alkylation to anions generated from 2,2-dimethyl-5-methylene-1,3-dioxane.

Method for preparing 2-methyl-1, 3-propylene glycol from isobutene

The invention discloses a method for preparing 2-methyl-1, 3-propylene glycol from isobutene. The method comprises the following steps: mixing isobutene with acetic acid and oxygen, and carrying out an oxyacetylation reaction under the action of a supported palladium-molybdenum catalyst to obtain 2-methylene propane-1, 3-diacetoxy, namely a compound (C); carrying out transesterification on the compound (C) under the action of a basic catalyst to obtain 2-methylene-1, 3-propylene glycol, namely a compound (D); and carrying out hydrogenation reaction on the compound (D) to obtain the 2-methyl-1,3-propylene glycol. According to the method, the 2-methyl-1, 3-propylene glycol can be generated with high selectivity, and the whole process is high in atom utilization rate, environmentally friendly and suitable for large-scale industrial application.

Synthesis of isofagomine and a new C6 pyrrolidine azasugar with potential biological activity

An efficient asymmetric synthesis of isofagomine, based on a precursor containing three differentiated hydroxyl functions, is described. The side product in the key alkylation step is converted into (2S,3R,4R)-2,4- bis(hydroxymethyl)-3-hydroxypyrrolidine, a new C6 pyrrolidine azasugar, which inhibits α-glucosidase from yeast.
