Preparation and application of monodisperse polyethylene glycol monomethyl ether modified propofol prodrug

Belonging to the field of organic chemistry and pharmaceutical chemicals, the invention discloses preparation and application of a monodisperse polyethylene glycol monomethyl ether modified propofol prodrug with a novel structure. Monodisperse polyethylene glycol monomethyl ether and propofol can be connected by an in-vivo degradable chemical bond to prepare a series of carbonic ester type and acetic ester type prodrugs respectively. By adjusting the length of the monodisperse polyethylene glycol monomethyl ether chain, the method can synthesize corresponding water-soluble propofol prodrugs, the longer the monodisperse polyethylene glycol monomethyl ether chain is, the better the water solubility is, along with the improvement of the water solubility, the prodrug can be made into aqueous solution preparations so as to avoid the defects of fat emulsion in propofol fat emulsions. The method provided by the invention has the advantages of simple reaction, mild conditions and low cost, andis convenient for industrial production.

Gold nanoparticles generated by thermolysis of "all-in-one" gold(i) carboxylate complexes

Consecutive synthesis methodologies for the preparation of the gold(i) carboxylates [(Ph3P)AuO2CCH2(OCH 2CH2)nOCH3] (n = 0-6) (6a-g) are reported, whereby selective mono-alkylation of diols HO(CH2CH 2O)nH (n = 0-6), Williamson ether synthesis and metal carboxylate (Ag, Au) formation are the key steps. Single crystal X-ray diffraction studies of 6a (n = 0) and 6b (n = 1) were carried out showing that the P-Au-O unit is essentially linear. These compounds were applied in the formation of gold nanoparticles (NP) by a thermally induced decomposition process and hence the addition of any further stabilizing and reducing reagents, respectively, is not required. The ethylene glycol functionalities, providing multiple donating capabilities, are able to stabilise the encapsulated gold colloids. The dependency of concentration, generation time and ethylene glycol chain lengths on the NP size and size distribution is discussed. Characterisation of the gold colloids was performed by TEM, UV/Vis spectroscopy and electron diffraction studies revealing that Au NP are formed with a size of 3.3 (±0.6) to 6.5 (±0.9) nm in p-xylene with a sharp size distribution. Additionally, a decomposition mechanism determined by TG-MS coupling experiments of the gold(i) precursors is reported showing that 1 st decarboxylation occurs followed by the cleavage of the Au-PPh 3 bond and finally release of ethylene glycol fragments to give Au-NP and the appropriate organics.
